Chapter 1 Introduction You need to You need to read this chapter if you want an overview of the Console Server product. read this This chapter provides introductory information about the Console Server, its chapter if associated components, software and configuration utilities. you want to... This chapter includes the following sections • About the Console Server on page 18 • Typical applications summary on page 20 • Console Server front and rear views on page 21.
About the Console Server The Console Server is a console server which allows you to communicate directly via the serial port to networked devices (such as routers, servers and so on) in order to perform system administration tasks. The Console Server allows system administrators to diagnose and fix from anywhere on the LAN/WAN or via a modem thus saving on administrator's time and costs to keep system disruption to a minimum.
See also Typical applications summary on page 20 and Console Server front and rear views on page 21.
Typical applications summary Managing devices over the LAN/WAN The Console Server allows the administrator to Telnet to the appropriate port on the console server. With the Console Server in band management functionality, administrators can gain access to attached devices from anywhere on the LAN/WAN provided they know the IP addresses. The Console Server also allows access to multiple devices simultaneously.
Console Server front and rear views The Console Server is a network access server with front-mounted RJ45 serial ports. It is designed for use in a rack. The serial ports are RS232. The product has 10/100BaseT and AUI network connections and an Administration port for system management. The next picture shows the front view of a 24 port unit. Console Server front view You can mount the Console Server in a 19 inch rack, on a wall or on a desk.

Chapter 2 Installation You need to read You need to read this chapter if you want install the Console Server. this chapter if you This chapter provides task oriented information about installing the Console Server, its associated want to... components, software and configuration utilities.
General installation procedure The general procedure for installing and setting up your Console Server is as follows; 1. Note Install your Console Server in a rack or on a desktop as required using the procedures described in Rack mounting your Console Server on page 25 and Desk mounting your Console Server on page 27. If you are stacking multiple units on a desktop see Multiple stacking your Console Server on page 28 for the maximum advisable units to stack. 2.
Rack mounting your Console Server To mount a single Console Server into a 19 inch rack, use the two mounting brackets and four screws provided with the unit. Caution When mounting several Console Server units in a 19” rack, you must not stack more than 3 units without leaving an air gap between them. Caution Observe maximum ambient operating temperatures within a rack; you may have to use forced air cooling.
Black Box Console Server user guide 26
Desk mounting your Console Server To prepare the Console Server for use on a desk use the four self-adhesive rubber feet provided with the unit. Stick the four feet to the underside of the unit, one in each corner, approximately one inch from each adjacent edge. 1 inch (2.5 cm) 1 inch (2.
Multiple stacking your Console Server When stacking your unit on a desk we recommend that you stack no more than three units high in a 0 to 40 degrees centigrade environment.This precaution ensures that you keep within the maximum operating temperatures of the units. Caution When desk mounting multiple Console Server units, make sure you fit the rubber feet to all units before stacking to assist ventilation.
LED guide During bootup you should see power and network LEDs display the following colours.
Console Server during normal operations Black Box Console Server user guide 30
RJ45 LEDs There are bi-colour LEDs on the RJ45 connectors on both the front and rear panels.
Selecting AUI or 10/100 Base T interface Before performing the initial configuration of your Console Server unit, you need to select the type of interface you want to use from either AUI or 10/100Base-T (Default setting is 10/100Base-T). To do this proceed as follows; Note To display the currently selected interface type, at the command prompt, type show hardware and press the Enter key. The resulting display will include the currently selected hardware type.
Setting up an IP address Setting up an IP address automatically using DHCP This section includes the following; • Set up procedure on page 33 • About DHCP on page 35 Set up procedure To set up an IP address automatically using DHCP proceed as follows; Note For details of the BOOTP/DHCP tags (client information items) that are supported by both BOOTP and DHCP see Appendix F BOOTP. In addition on Microsoft Windows NT, DHCP allows for the configuration of WINS server names.
2. Connect your Console Server to the network and turn on the unit. The IP address and any other configuration information will now be set up automatically.For more information see About DHCP on page 35.
About DHCP You can use DHCP to perform the following actions on a single or multiple Console Server (the ‘unit(s)’)s on its/their boot-up: auto-configure with minimal information; e.g. only an ip address auto-configure with basic setup information (ip address, subnet mask, broadcast address, etc.
The DHCP server checks the ethernet address and looks for a matching address in its DHCP tables: - if a matching ethernet address is found the DHCP server will reply to the unit; the reply will contain network configuration information. This information is listed in the DHCP tables for that particular unit (identified by its hardware address). The unit then boots using the information sent to it. - if no matching ethernet address is found the DHCP server does not reply; the unit boots from internal memory.
The major differences between BOOTP and DHCP are: • BOOTP is largely reliant on a network client's low level Ethernet address (MAC address) for client information look-up, DHCP has no such limitation, although it is still possible to associate a specific IP address to a specific MAC address. • Client information supplied by DHCP is supplied on a lease basis, that is to say that the client negotiates with the server for the lease of an IP address for a specific period of time.
Manually setting up an IP address This section includes the following; • Set up procedure on page 39 • Server form field descriptions on page 42.
Set up procedure To manually set up an IP address proceed as follows; 1. Set up a terminal or PC running terminal emulation. For examples of connection pinouts see Appendix A Cabling information. If you connect via the Admin Port you will see a display of diagnostic and bootup messages. Note that if you cannot emulate VT100, you will have to use the Command Line Interface (cli); (the cli commands are described in full in Appendix B The CLI commands). 2.
6. Within the server form, complete the fields by moving between the fields using the arrow keys. Use the key to backspace if necessary. For a description of the fields in this form see Server form field descriptions on page 42. Example settings for all the Console Server configuration fields are shown in the next picture: 7. When you have completed the form, press .
8. Accept the form; you will be returned to the Main Menu. You may want to save your configuration changes permanently; see Saving configuration changes on page 62 9. Reboot the unit. Rebooting will ensure that other network devices can communicate with it. Note If you set the port to authenticate by RADIUS only, users will not be able to dial in and connect if the network connection is down (no access to RADIUS server).
Server form field descriptions The server form fields are described in the next table. You can use this information to assist with setting values in Set up procedure on page 39. Parameter Description servername The familiar name for your Console Server. (also known as hostname or alias) Internet Address (IP Address) The Console Server’s unique address in the network. Broadcast Address The address used by the Console Server for sending information to all hosts on your network simultaneously.
Parameter Description both - (the default) firstly with the unit’s own user table. If the username is found in unit but the password is incorrect, an authentication request is sent to the RADIUS host. If the username is not found in the unit, authentication is passed up to the RADIUS host. (The exception is the ‘admin’ user; if you supply an incorrect password, the unit will not go to the RADIUS host; it will fail the authentication).
Parameter Description gui access this parameter controls access to the Console Server’s graphical configuration programme JETset. The default is ‘off’. When set to ‘on’ the admin user can access the JETset from a Web browser, using the unit’s internet address. Entry to the programme is then controlled by password. If you are not using the JETset to configure the unit, we suggest you set this parameter to ‘off’; access will be denied to any person who tries to connect to the unit from their browser.
Accessing the Console Server configuration software Logging onto your Console Server 1. From your host, telnet to Console Server. For example, telnet 192.65.1434.15 2. A login prompt is now displayed. 3. At the console, with the login prompt displayed, type admin and press . At the password prompt, type superuser and press . This is the default admin user password. The command line prompt will be displayed: e.g.
Setting up your network parameters Setting up the host table The Console Server needs to know the hostnames and internet addresses of the other hosts in the network (or any hosts anywhere on the Internet) which you want to communicate with on a regular basis. For example, gateways, RADIUS, servers and so on. These hostnames are added to the unit’s Host Table. You can add up to twenty hosts. To do this; 1. From the Main menu, select ‘Network Configuration’. 2.
2. Type in the name of the host (14 characters maximum) and press .
Changing a Host This option enables you to add or change a host’s internet address: To change a host (set host, show host): 1. Within the Host Table menu, Select ‘Change Host’ from the Host Table menu; This form will list all hosts added to the host table. The default internet address is 0.0.0.1. 2. Enter the correct internet address of each host. Use the key to backspace if necessary.
Deleting a host This option enables you to delete an entry from the host table. If a host is referenced by a pre-defined session, or is defined as a gateway or name server, you won’t be allowed to delete it. To delete a host (cli command delete host) 1. Within the Host Table menu, When you select ‘Delete Host’, the host table will be displayed: 2. Select the host that you want to delete and press . You will be asked to confirm the deletion: 3.
Changing the Admin Password cli syntax: set user password To change the Admin password proceed as follows; 1. 2. Within the Users menu, select ‘Set Password’. From the list now displayed, select ‘admin’ user. You will be prompted to enter a password. This can be up to sixteen characters. Use the key to backspace if necessary. 3. At the prompt, enter the password and press . You are now prompted to enter the password a second time to confirm your choice. 4.
RADIUS configuration This section includes the following: • Set up procedure on page 51 • RADIUS parameters description on page 54. Set up procedure To configure how the Console Server interacts with the RADIUS host or hosts: 1. From the Main menu, select ‘radius configuration’: 2. Within the radius configuration menu, select from one of add/delete authentication/accounting host. A list of hosts from the unit’s host table is now displayed (see Setting up the host table on page 46): : 3.
4. Key a maximum of sixteen alphanumeric characters. To change the secret you must delete the host and then add it again; when you add a host you are prompted for a secret.The first host entered becomes the primary authentication/accounting host, the next host entered becomes the secondary host. You can enter a maximum of two hosts in each of the fields. You must enter the same secret in the RADIUS host (see your RADIUS documentation); the secret is not transmitted over the network.
7. Tip Accept the form; you will be returned to the menu.
RADIUS parameters description The RADIUS parameters are as follows: retry (for authentication) the number of times the unit will re-send a request to a RADIUS authentication host, before re-presenting another login to the user. (for accounting) the number of times the unit will re-send a request to a RADIUS accounting host, before understanding that the accounting request has failed. The default retry value is 5; the unit will try the primary host up to 5.
auth_port - the UDP port number for RADIUS authentication. The default value is 1645 which should match most RADIUS implementations. Change this value if your RADIUS host is using a different UDP port number. acct_authenticator - a flag to instruct the unit to check the authenticator field in the accounting reply transmission from a RADIUS host to the unit. The authenticator field contains the secret, encrypted.
DNS configuration You can enter the addresses of two DNS hosts in the Console Server (the ‘unit’); one will be the primary host, the other a secondary host. The DNS hosts do not have to be the same hosts as entered in your unit’s host table. On a remote access connection the unit will transmit these addresses to a dial-up Windows NT/95 client. Therefore, your remote user does not have to configure DNS parameters in his/her computer. For more information on DNS see Appendix D RADIUS & Networking.
WINS configuration WINS (Windows Internet Name Service) is a database of hostnames and corresponding internet addresses. It is a Microsoft specific name resolution service. The basic function of WINS is the similar to DNS, i.e. it maps computer names to TCP/IP addresses for client computers on a network. For more information on WINS see Appendix D RADIUS & Networking. You can enter the addresses two WINS hosts in the unit; one will be the primary host, the other a secondary host.
Configuring network gateways Gateways are hosts that connect Local Area Networks (LANs) together. If you want to access a host which isn’t on your local network you will be connected via a gateway. Gateways route data via other gateways until the destination local network is reached. There are three types: • Default - this is a gateway which provides general access beyond your local network. • Host - this a gateway reserved for accessing a specific host external to your local network.
Adding a gateway To add a gateway proceed as follows: 1. From the Network Configuration menu, select ‘Gateway’. 2. From the Gateway menu, select ‘Add Gateway’. 3. From the host table now displayed, select a host. Note that you can define a host only once as a gateway. When you have added a gateway, you must define its type. 4. From the Gateway menu, select ‘Change Gateway’. The Gateways form is now displayed (for example): This form lists all gateways defined for your network.
Deleting a Gateway delete gateway If a host on your network is retired from gateway duty, you can use this option to delete it from the list of gateways. Note that the host will NOT be deleted from the host table. To delete a gateway proceed as follows: 1. From the Network Configuration menu, select ‘Gateway’. 2. From the Gateway menu, select ‘Delete Gateway’ to list your gateways: 3. Delete the gateway you require from the list.
Verifying your network installation To check that you have installed the Console Server (the ‘unit’) successfully proceed as follows; 1. At the command prompt, try to ping a remote host by typing the following command: ping hostname Choose a host that you have defined in the host table. If no packet loss is reported, your unit is ready to use.If the command returns an error, refer to the ping cli command.
Saving configuration changes Saving to non-volatile memory To save your configuration settings to non volatile memory proceed as follows; 1. After making changes to the configuration exit the text menu screen (form) you are using. The ‘options’ form now appears: 2. Within the options form select ‘accept and exit form’ to retain your changes in RAM (volatile memory). 3.
Saving to a file cli syntax: netsave You can also save your configuration information to a file on a host. This can only be done in the cli; See Appendix B The CLI commands.
Setting date and time The Console Server (the ‘unit’) has a real-time clock which you can set and view. It is battery-backed and therefore will operate when power is off and over reboots. The clock is year 2000 compliant. To set the date and time on your unit proceed as follows; 1. From the Main Menu select Hardware. The hardware form is now displayed. Only the date and time fields are user editable. : 2. Identify your unit using the hardware information displayed.
Performing a soft reboot To perform a soft re-boot (cli syntax: reboot); 1. From the Network Configuration menu, select ‘Reboot’. You will be asked whether you wish to save your configuration changes to nonvolatile memory: 2. At the prompt, type y and press the Enter key. The unit will close all connections and then reboot.
Restoring factory default settings Resetting to factory defaults using software This feature enables you to reset the unit to its default settings. This will clear all configuration data entered by the admin user, and all user accounts, except the default admin user, will be deleted. To reset to factory default settings from within the software (cli syntax: reset factory): 1. From the Network Configuration menu, select ‘Reset’. You will be asked to confirm the reset: 2.
1. Use the tip of a pen or pencil to press the reset switch located on the rear of the unit. The Console Server will then reboot and reset itself to factory default settings.

Security The Console Server has a number of security features built in that can be enabled or disabled depending on the security level required. These features include: • Telnet access - Login and password required. See set line on page 166 in Appendix B The CLI commands. • SSH access - Makes ports only accesible via SSH connections. See Accessing devices via SSH on page 118 in Chapter 4 Using your Console Server.
Viewing and editing your line settings Lines set to reverse Telnet by default cli syntax: set line A reverse telnet connection enables a TCP/IP host on the local network to establish a login connection via a Console Server (the ‘unit’) port on a non-TCP/IP machine external to the network, such as routers, servers and so on. A Typical Reverse Telnet Configuratio n To set up a reverse telnet connection, follow these steps: 1.
3. Assign a TCP port number to the unit port using the ‘CS Port’ field. This TCP port number will be used by any host wanting to access the unit port. If you select a TCP port being used by another process, a connection will not be established (By default, lines are set to TCP port 10001 to 10024 for each port. For example, Line 1 10001, Line 16 10016). 4. Do not configure the idle and session timers; these timers have no effect on reverse telnet connections. 5.
6. The line should now be configured similar to that shown in the next picture: 7. Press to exit; if you do not wish to save your changes press the key. 8. If you want to configure all lines with the same parameters, refer to Resetting the line to default on page 111. Lost password cli syntax: set user If you are an admin user, and you lose your password, there is no way of logging in without it. This restriction is for security reasons.
Configuring a dial in line Introduction to SLIP and PPP connections This section deals with setting up SLIP and PPP connections on a line. There is also a summary of the configurable features of modems. Deciding whether to use SLIP or PPP If you require any of the features listed below, use PPP, otherwise SLIP should be sufficient. IP Address Negotiation. SLIP provides no mechanism for informing the other end of a link of its IP address, whereas PPP will do so. Error Checking.
Setting up the line cli syntax: set line, show line 1. From the Line Configuration menu, select ‘Line Settings’. 2. Within the Line settings menu, select a particular line; e.g. line 3. The line form will be displayed (default values shown in the next example): 3.
Service option Description PPP When you want a remote access service connection using PPP, or when you want to use the unit as a router with PPP. In both cases the user (whether real or dummy) will be authenticated within PPP (provided you use Security - PAP or CHAP). cslogin When you want a remote access service connection using SLIP.
Service option Description Session Timer router use only Enter a period in seconds for which the session timer will run. Use this timer to forcibly close the session (connection). When the session timer expires the unit will end the connection. The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until you kill the line. The maximum value is 4294967 seconds (equal to 49 days, approximately). 4. cli syntax: 5. add modem 6.
Configuring SLIP cli syntax: To configure the SLIP parameters proceed as follows; set slip line, 1. From the Line Configuration menu, select ‘SLIP’ and then select a line. show slip line The SLIP form is now displayed (default values shown): 2. Within the SLIP form, set the parameters listed in the next table: Option Description Local ip address This is the IP address of the unit end of the SLIP link. For routing to work you must enter an IP address in this field.
Option Description Remote ip address This is the IP address of the remote end of the SLIP link. This must be specified. Choose an address which is part of the same network or subnetwork as the unit (see comment in ‘Local ip address’ above). Enter the remote ip address in dot notation, e.g.192.101.34.146 (or in the cli, example syntax would be: set slip li 5 ripaddr 192.101.34.
Option Description VJ Compression This determines whether Van Jacobson compression is used on this link; i.e. whether you are using SLIP or C-SLIP (compressed SLIP). The choices are ‘on’ (C-SLIP) or ‘off’ (SLIP); the default is ‘on’. Select ‘on’ will turn on VJ compression. C-SLIP greatly improves the performance of interactive traffic, such as Telnet or Rlogin; see Configuring a dial in line on page 74 for more information. In the cli, example syntax would be: set slip li 1 vj on.
Configuring PPP This section describes how to configure a dial in line using PPP and includes the following: • PPP configuration procedure on page 82 • PPP form field descriptions on page 83. An example of a remote access connection using PPP, including the setup of a remote user is described in Configuring a dial in line on page 74. PPP configuration procedure cli syntax: To configure a line using PPP proceed as follows; set PPP line, show PPP 1. Within the Line Configuration menu, select ‘PPP’.
PPP form field descriptions This section describes the fields and settings used in the PPP form referred to in PPP configuration procedure on page 82. The following fields are described in this section. • Local ip address on page 84 • Remote ip address on page 84 • Subnet Mask on page 84 • ACCM on page 85 • Max.
Local ip address This is the IP address of the unit end of the PPP link. For routing to work you must enter a local IP address. Choose an address which is part of the same network or subnetwork as the remote end; e.g. if the remote end is address 192.101.34.146, your local ip address may be 192.101.34.145; (in the cli, example syntax would be: set ppp li 6 lipaddr 192.101.34.145) To see an example of ip address usage, refer to ‘Setting up an IP address on page 33’.
ACCM This allows the specification of an accm (asynchronous control character map) of characters that should be escaped from the data stream. This is entered as a 32 bit hexadecimal number with each bit specifying whether or not the corresponding character should be escaped. The bits are specified most significant bit first and are numbered 31-0. Thus if bit 17 is set, the 17th character should be escaped i.e. 0x11 (XON). So entering the value 000a0000 (in the cli, e.g.
CHAP challenges a client/device at regular intervals to validate itself with a username and a response, based on a hash of the ‘secret’ (password). A timer operates during which successful authentication must take place. If the timer expires before the remote end has been authenticated successfully the link will be terminated. With both PAP and CHAP make sure the unit and the remote client/device have the same setting. e.g.
User Complete this field only if you: • have specified PAP or CHAP (security protocols) in the ‘Security’ field, and • you wish to dedicate this line to a single remote user, and this user will be authenticated by the unit, or • you are using the unit as a router (back-to-back with another unit). ‘User’ is the name the remote device will use to authenticate a port on this unit (the opposite of the parameter ‘Remote User’).
• you wish to dedicate this line to a single remote user, and your user will be authenticated by the unit, or • you are using the unit as a router (back-to-back with another unit). ‘Remote User’ is the name the unit will use to authenticate the port on the remote device (the opposite of the parameter ‘User’). Your unit will only authenticate the port on the remote device when PAP or CHAP are operating.
Protocol This determines whether compression of the PPP Protocol field shall take place on compression this link. The choices are ‘on’ or ‘off’; the default is ‘on’. For most applications this should be enabled; i.e. ‘on’. In the cli example syntax would be: set ppp li 1 proto_comp on. VJ Comp This determines whether Van Jacobson Compression is used on this link. The choices are ‘on’ or ‘off’; the default is ‘on’. Select ‘on’ will turn on VJ compression. Select ‘on’ will turn on VJ compression.
Configure This parameter specifies the maximum time in seconds that LCP (Link Control req. timeout Protocol) will wait before it considers a ‘configure request’ packet to have been lost. (in the cli example syntax would be: set ppp li 8 cr_tmout 3). Terminate This parameter specifies the maximum time in seconds that LCP (Link Control req. timeout Protocol) will wait before it considers a ‘terminate request’ packet to have been lost; (in the cli example syntax would be: set ppp li 24 tr_tmout 3).
Configuration area PPP line parameter ROAMING CALLBACK result other actions necessary Value OFF - ON for the particular user you must set (fixed) callback to ‘on’. See Configuring a user account on page 100. Unless fixed callback is set to on for user, he/she cannot receive roaming callback. the user must initially dial into the unit on a line where roaming callback is set to ‘on’. You must therefore provide the user with the telephone number for this type of line(s).
Challenge_ sets the interval in minutes at which the unit will issue a CHAP re-challenge to the interval remote end. The default value is 0 (zero) meaning CHAP re-challenge is disabled. During CHAP authentication an initial CHAP challenge takes place, and is unrelated to CHAP re-challenges. The initial challenge takes place even if re-challenges are disabled. Some PPP client software does not work with CHAP re-challenges so you may wish to leave the parameter disabled in the unit.
Configuring a modem A summary of the configurable features for modems is listed below. Note cli syntax: • set line set line • add modem • set modem all references to modems apply equally to ISDN Terminal Adaptors you can set the ‘dial’ parameter to ‘in’, ‘out’ or ‘none’ (default ‘none’) in the line parameters sub-menu. Setting ‘in’ or ‘out’ tells the unit that there is a modem on that line. The unit will communicate with the modem through various RS232 signals.
Configuring users You need to configure user accounts on the Console Server (the ‘unit’) for those users who are tasked with administering the attached devices or Remote Access connections. If you are using a RADIUS host you may not need user accounts for those users who are authenticated by the RADIUS host; see Configuring a dial in line on page 74.
Black Box Console Server user guide 94
About user accounts and RADIUS Overview You can have a maximum of 32 user accounts on the Console Server. You will also be able to configure user accounts on the RADIUS host. Therefore some users can be authenticated by the unit, other users by RADIUS. You could have other combinations of maintaining user accounts; i.e. duplicated on both the unit and the RADIUS host or, alternatively all user accounts stored on the RADIUS host only.
Black Box Console Server user guide 96
Example RADIUS user file: telnet service davePassword = "garage" User-Service = Callback-login, Login-Host = 192.101.34.199, Login-Service = Telnet, Login-TCP-Port = 23, Class = "Indirect Sales Group", Session-Timeout = 1800, Idle-Timeout = 600, CallBack-Number = "3592" An explanation of the file shown in Example RADIUS user file: telnet service on page 98 is as follows: - the file contains a mixture of user parameters (e.g. callback-number) and line parameters (e.g. login-host).
Adding a user account To add a user account, proceed as follows; 1. Within the Users menu, select ‘Add User’ (cli syntax: add user). 2. Enter a username, maximum sixteen characters (do not use spaces). If your user is equipment allocate an appropriate name, e.g. barcode2. 3. Enter a password, maximum sixteen characters (do not use spaces). Re-enter the password. Admin users can change user passwords using the ‘Set Password’ feature described in Changing a user’s password on page 109.
Configuring a user account The section includes the following: • Configuration procedure on page 100 • User form field descriptions on page 101. • About user levels on page 108 • CLI prompts on page 108. Configuration procedure To configure a user account, proceed as follows; Tip Your configuration will only be used if the user is authenticated by the unit.
User form field descriptions This section describes the fields within the user form detailed in Configuration procedure on page 100.
Service Instructs the unit to start a user service by selecting one from the following list (once the user is authenticated successfully): csprompt: a login on the unit (the default setting). Use this service for you as the system administrator, or for users who wish to run a single or multiple sessions on Terminal Server connections; these sessions are configured within the unit. Telnet: a Telnet service provided by the unit.
TCP Port No (ignore this field unless you have selected a user Service of ‘telnet’) (telnet only) enter the TCP/IP port number of the host with which the unit should start the telnet service. The default port is 23; in most cases you should leave the value at default. phone number Enter a telephone number for the unit to call back the user; do not use spaces. You must also have ‘callback’ set to on. (The number you enter is unrelated to the ‘phone_number’ or ‘dial’ parameters you can set for a line).
255.255.255.255 - specified by user. The unit will prompt the user for an IP address or hostname, when the telnet or rlogin service is started. When the user service is set to Telnet, Rlogin or TCP Clear, the unit will give the user two attempts the enter the required information. callback n.n.n.n - (where ‘n’ is a number) you specify in this field the IP address of a host with which the unit should start the telnet or rlogin service for this user.
Configu ration area Callback for a user User parameter CALLBACK (fixed) result other actions necessary Value OFF - ON the line must have authentication: for SLIP, set line service to CS_login (set user service to slip) for PPP, set line service to PPP, and turn on either PAP or CHAP (set user service to PPP) enter a telephone number for the unit to dial the user The unit will not provide any type of callback to the user, neither fixed nor roaming.

framed ip (use only when the user service field is set to ‘slip’ or ‘ppp’) this is the ip address of the remote user. Enter the address in dot decimal notation as follows: 255.255.255.254 (default) - if you enter this value, the unit will use the remote ip address set for the line; see Configuring SLIP on page 78 or Configuring PPP on page 82. 255.255.255.
framed (use only when the user service field is set to ‘slip’ or ‘ppp’) this parameter compression determines whether Van Jacobsen Compression is used on the link. Select either ‘on’ or ‘off’ (default is ‘off’). VJ compression is a means of reducing the standard TCP/IP header from 40 octets to approximately 5 octets. This gives a significant performance improvement particularly when interactive applications are being used.
Changing a user’s password To change a user’s password, proceed as follows; 1. Within the Users menu, select ‘Set Password’ (cli syntax set user). 2. Select a user from the list displayed. You will be prompted to enter a password. This can be up to sixteen characters long (do not use spaces). Use the key to backspace if necessary. 3. Enter the password and press . 4. When prompted, re-enter the password and press .
Configuring Break Pass Through The Console Server will not send break signals on power cycles. It is also configured not to allow break signals to be sent through to attached devices by default. However, some administrators may wish to be able to send the break signal i.e. to take a Sun Solaris system to the Open Boot prompt. To enable this feature, please use the following CLI command to enable/disable proprietary inband SSH break signal processing as well as existing Reverse Telnet break signal.
Resetting the line to default This feature enables you to reset the serial line which you are configuring to the default settings. It is available in the Line Settings form (under the Line Configuration Menu). To reset the line to the default settings proceed as follows; 1.

Chapter 4 Using your Console Server You need to You need to read this chapter if you want information on how to use the Console read this Server as a console server. chapter if This chapter provides task orientated information on using the Console Server as a you want to... console server.
Introduction Once the unit has been configured and users added using the procedures given in Chapter 2 Installation and Chapter 3 System administration, you can begin to use it as a console server. There are three methods of accessing the devices attached to the serial ports: • Accessing devices via telnet from the LAN. See page 117 • Accessing devices via SSH from the LAN. See page 118 • Accessing devices via modems on a dial in link using PPP.
Accessing devices via Telnet from the LAN Terminal emulators In order to perform this function you must have a system capable of running a telnet session. Microsoft Windows does have an implementation of telnet but it is limited. You may wish to use a terminal emulator package such as: Term - Century Software - www.censoft.
Accessing devices via SSH In order to perform this function you must have a system capable of running an SSH session. The Console Server supports both SSH version 1 and SSH version 2. You may wish to use a SSH client software such as : PuTTY - PuTTY is a free implementation of Telnet and SSH for Win32 platforms available from the web. SSH Setup Procedure To connect to a specific device using SSH you must configure the Console Server to support the SSH protocol. By default, the SSH protocol is disabled.
3. You will be prompted to generated the SSH keys associated with the version of SSH selected. This initial generation of key takes a few minutes and you will be asked to confirm if you want to proceed with the key generation. The SSH key generation is only performed once unless the Console Server is reset back to factory default. 4. During key generation, an indicator at the bottom of the screen shows the keys being generated.
5. Once the keys have been generated, you will be prompted to save your settings. 6. Each line which you require secure access to will have to be configured for reverse ssh. Go to the appropriate line configuration setting to set the line service to rev ssh NOTE: the line will only support the SSH protocol which was selected in the server configuration. 7. Save your line configuration settings and SSH protocol is now supported.
• SSH protocol enabled and associated key generated on the Console Server • Disable decompression on SSH client software – feature is not supported on Console Server Access procedure To access a device over a secure SSH session, proceed as follows: 1. Set up your SSH client software to connect to the ip address of the Console Server and set socket number for the correct port. 2. Setup your SSH client software to match the SSH protocol version that is configured on the Console Server unit. 3.
Accessing devices via modems using PPP For this method you will need to setup one of the serial ports for PPP (see Configuring a dial in line on page 74 in Chapter 3 System administration). With a line configured for PPP you will be able to dial in for a PC using Microsoft's dial up networking. A remote user will dial up by using dial up networking and once authenticated by the Console Server will be connected to the network.
Accessing devices via modems using a dumb device For this method you will be using either a PC with a terminal emulator or a dumb terminal. To setup a serial port for this method proceed as follows: 1. Login in to Console Server as admin. 2. At Console Server prompt type screen and press enter. The Main menu now appears. 3. From the Main menu, select Line settings. 4. Select the line number you wish to configure. 5. Set the service to cslogin. 6.

gui-status use this parameter to control access to the unit’s graphical configuration programme, JETset . The default is ‘off’. When set to ‘on’ the user with username ‘admin’ can access the JETset program from a Web browser, using the unit’s internet address. Entry to the programme is controlled by password. If you are not using JETset to configure the unit, we suggest you set this parameter to ‘off’; access will be denied any person trying to connect to the unit.
OEM-mode The OEM_mode field is a 4 digit hexadecimal number. The number is defined as a bit field, each bit being a different option that is either enabled or disabled. The following options are currently used :Bit Value Option 0 1 Login prompt uses OEM1 string When set, and a custom language file is in use, the login prompt will use the string defined in the language file as the login prompt instead of the 'login: ' default prompt. Note that this option applies to ealier versions of the software only.
OEMmode 8 also enables a per-connection keepalive TCP keepalive feature - after approx 3 minutes of network connection idle time, the connection will send a gratuitous ACK to the network peer – thus either ensuring the connection stays active OR causing a dropped connection condition to be recognised by the reverse raw service. Without OEM mode 8 set the software continues to work as before.
services This command allows the ability to enable/disable specific processes in the Console Server.The services field is a 4 digit hexidecimal number. The number is defined as a bit field, each bit being a different process that is either enabled or disabled. By default, all processes are enabled with the flag set FFFF). This service flag will be saved when configuration is saved to FLASH.

Appendix C SNMP You need to You need to read this appendix if you want information on the Console Server read this support of SNMP. appendix if This appendix describes the Console Server support of SNMP. you want to... This appendix includes the following sections; • Overview on page 204 • Configuring SNMP support on page 205 • Summary of objects in the private MIB on page 207 • Private MIB definitions on page 209 • Network management on page 213.
Overview The Simple Network Management Protocol (SNMP) is a protocol for access and control of network management information on TCP/IP networks. Console Server (the ‘unit’) provides an SNMP agent, able to respond to SNMP requests generated by SNMP Managers. The unit’s implementation of SNMP is compatible with MIB II (RFC 1213) as specified by the SNMP SMI document (RFC1155). For a full description of SNMP, refer to your SNMP documentation.
Configuring SNMP support To configure for SNMP support proceed as follows; 1. cli syntax: 2. set contact set location From the Main Menu select ‘network configuration’ and then ‘snmp’. Select ‘snmp contact information’ to configure the SNMP sysContact and sysLocation objects; an example screen is shown below: add trap delete trap Select ‘edit traps’ to create up to four trap communities; an example screen is shown below: add community delete community 3.
The unit’s SNMP Agent will only provide information to hosts defined by an SNMP community.

Appendix D Upgrading your firmware You need to You need to read this appendix if you want information on upgrading the Console read this Server firmware. appendix if This appendix provides task orientated information on upgrading the Console Server you want to... firmware.
Introduction If you have been supplied with a software upgrade this appendix shows you how to install it. To check the version of software your unit is running see the information displayed at the top of any menu display, that is: user [admin] xxxxxx 1.0 telnet 1 Compare this with the version number of software which you have obtained. If you have a more recent version of software, you should install it.
Saving your existing Configuration Saving the existing configuration will allow the configuration information in the unit to be restored at a later date. Note Upgrading the software on the unit does not alter the stored configuration information which will be preserved during the upgrade. The procedure requires the presence of a write enabled empty file on a suitable network fileserver. The fileserver must have the TFTP (Trivial File Transport Protocol) service enabled and running.
TFTP configuration cli syntax: You can configure TFTP in the Console Server (the ‘unit’). It is used for transferring set server tftpfiles to/from a host; the files could be, for example, configuration, new software or custom language files. From the Network Configuration Menu, select ‘tftp’; you should see the following: tftp retry [5 timeout[3 ] ] retry should tftp fail, retry is the number of retries the unit will make to transfer a file to/from a host. Enter a value between 0 and 255.
Writing to FLASH memory The Console Server will load the software into RAM, perform checks, and then write the software into FLASH memory. The writing to FLASH will take a few minutes and during this time the unit will not respond to user input. While the new software is being loaded into FLASH memory, the power and network LEDs on the front of the unit display a pattern.
Using BOOTP from a boothost When installing with BOOTP, the SW_FILE parameter in your BOOTFILE will need to be changed to point to the new software image. We recommend that you keep the name of the image file as supplied as this will guarantee that the software is recognised as a new version by the existing software installation. Reboot your unit. The new software will download and write to FLASH memory, see Writing to FLASH memory on page 219.
Upgrade using JETset, the web browser interface 1. Start JETset by pointing your network browser at the Internet Address of your the unit. 2. Log in as the Admin user and select file transfer from the main menu. 3. Complete the file transfer form by selecting software download from the pulldown menu, and completing the internet address of the TFTP server and the download software image filename. 4. Select save from the main menu to start the download process.
After any software upgrade you should always check that DHCP is set to ON if you require BOOTP/DHCP to configure your unit.
Appendix E Summary of Line Service Types You need to You need to read this appendix if you want a summary of line service types for the read this Console Server. appendix if This appendix provides a list of line service types for the Console Server. you want to... This appendix includes the following sections; • List of line service types on page 224.
List of line service types When you are configuring a line on the Console Server (the ‘unit’) you will find a parameter for a line called ‘service’. The detail of types of line service available are shown below. Note do not confuse line ‘service’ with user ‘service’. User ‘service’ is a completely different parameter from line ‘service’ and is used by the unit in different ways.
Line Service Type Description/Uses Example Reverse Raw Simple pipe between a TCP/IP To access printers or dialout modems host and a machine/device (with separate host-based print/modem attached to a port on the unit. handling software). The connection is set up from the TCP/IP host on the local network to the unit (the opposite of Direct Raw and Silent Raw). Reverse Telnet (Default) Enables a TCP/IP host to To access machines like routers, establish a login connection on firewalls, servers and so on.

Appendix F BOOTP You need to You need to read this appendix if you require information about BOOTP for the read this Console Server. appendix if This appendix provides information about BOOTP for the Console Server. you want to...
Introduction You can use BOOTP to perform the following actions on a single or multiple Console Server (the ‘unit(s)’)s on its/their boot-up: • auto-configure with minimal information; e.g. only an ip address • auto-configure with basic setup information (ip address, subnet mask, broadcast address, etc.
How BOOTP works On bootup or power-up, the unit will send a broadcast request to the BOOTP server(s) on the network. The request contains the ethernet address of the unit; it asks for network configuration details (internet address, subnet mask, etc.). This process is shown on page 229.You can stop the BOOTP server from replying to the unit; see page 236.
A configuration file (if you specify one) contains general configuration parameters; these parameters will have been created from another unit and saved to a file. In the bootp response the minimum parameters to specify are :ht and :ha There is no minimum number of parameters to specify in the bootfile or configuration file; unspecified parameters will remain unchanged in the unit’s memory. After processing the BOOTP response the unit will download additional files.
How to setup BOOTP Your nominated BOOTP server should be on the same network as the unit(s). The BOOTP server can also be on a different segment of the same network, provided that segment is connected by a bridge. You can locate your BOOTP server on another network to the unit; this means that the bootp request and replies have to pass through a router or gateway.
ht (hardware type) set to 1 (=10Mb ethernet). ha (hardware address) the ethernet address of the unit. ip (internet address) enter the ip address to assign to the unit. sm (subnet mask) enter the subnet mask of the unit. hn (host name) enter as :hn:\ which causes the name at the start of the file (Console Server_blue) to be allocated to this unit. bf (bootfile name) enter the name of the file containing specific configuration information; see An example bootfile on page 234.
Gateways are detailed in Section Chapter 2 Installation.
The bootfile If you wish to download basic configuration information to the unit you must create a bootfile. This file is a text file formatted in a particular style; an example is shown at An example bootfile on page 234. Note An example bootfile The bootfile must be located on the same host as the bootptab file # cat xxxxxxp.bfc SW_FILE192.65.144.95:/src/pscx/sw/xxxxxx.bin CONFIG_FILE192.65.144.95:/src/pscx/cfg/jconfig.0183 GUI_ACCESSyes AUTH_TYPE0 IP_HOST192.101.34.
6. If a domain name and nameserver are configured, either in the bootptab entry or in the unit’s memory, you can replace ip addresses with hostnames in lines specifying additional files; e.g. SW_FILEsophocles:/src/pscx/sw/xxxxx.
Parameter Value Brief Meaning Fuller explanation TFTP_RETRY numeric; e.g. 5 number of tftp attempts before aborting TFTP configuration on page 218 TFTP_TMOUT numeric; e.g.
• in bootptab file entry for a single unit on page 231 on page 231, place a hash before all the lines, e.g. # :ht=1:\ # :ha=0080ba000057:\ .. # :gw=192.101.35.254:\ • in bootptab file entry for multiple units on page 238 you would place a hash before the line referring to each unit; e.g: # xxxxx_2:ht=1:ha=0080ba000025:\ # ip=192.101.34.
Booting multiple units You can boot mutliple unit’s simultaneously using BOOTP; we recommend you alter the format of your bootptab file entry, as shown in bootptab file entry for multiple units on page 238. You make one set of parameters in a single area (in this example ‘common’) and point each unit’s entry to this area called ‘common’. bootptab file entry for multiple units common is the collective name for the list of information in this file common:\ :bf=/usr/js/xxxxxxp.cus:\ :sm=255.255.255.
4. You will see that all the unit’s are being directed towards the same bootfile (as listed in the ‘bf’ field in the area ‘common’). This is acceptable - however all your the unit’s will have the same configuration parameters. 5. The bootfile must be on the same host as the bootptab file entry.
Multiple BOOTP servers You may well wish to have a secondary BOOTP server as a back-up to the primary BOOTP server. The unit will operate with BOOTP when you have a second, third or more BOOTP servers on your network. During a reboot the unit processes the first BOOTP reply received and ignores subsequent replies. If the bootptab file entries are identical on all your BOOTP servers the first reply received by the unit will be the same as the other replies.
Our example entry in a BOOTPTAB file xxxxxx_3:\ :ht=1:\ :ha=0080BA00004b:\ :ip=192.65.146.120:\ :ds=192.165.144.6:\ :sm=255.255.255.0:\ :hn:\ :bf=/test:\ :dn=xxxx.co.uk 5. Create the bootfile specified in the above entry; i.e. file ‘test’: Our example bootfile # cat test SW_FILE192.65.146.71:/xxxxxx.fls GUI_ACCESSyes AUTH_TYPE0 IP_HOST192.65.146.71 SECURITYno TFTP_RETRY3 EXTRA_TERM1homer:/src/pscx/et/et1.0183 EXTRA_TERM2homer:/src/pscx/et/et2.0183 EXTRA_TERM3homer:/src/pscx/et/et3.0183 # 6.
7. Reboot the unit. After receiving details from the bootptab file, the unit should download the bootfile and the software file. The unit should then place the new software file into FLASH memory.
Appendix G JETset You need to You need to read this appendix if you want information on the Console Server JETset read this utility. appendix if This appendix provides task orientated information on using the describesConsole you want to... Server JETset utility.
Introduction to JETset Once you have allocated an ip address, you can use the Graphical User Interface, named ‘JETset’. This is a web-based program which you access from the web browser on your networked PC/computer. See JETsethome page on page 244. A summary of the program is in JETset program summary on page 249.
To access JETset 1. Make sure you set ‘gui_access’ to ‘on’, see Chapter 2 Installation 2. Open your web browser and enter the ip address of your Console Server; e.g. http://192.101.34.211 You should be presented with the login page: The program prompts you for a password (for user of name ‘admin’). Caution the only access permitted is username ‘admin’. Console Server assumes this username and so prompts you for the password for this user.
Using JETset using JETset Navigate by selecting these buttons If you have made changes, remember to save them before moving to another option Note the following guidelines about JETset: • JETset uses the ‘Frames’ feature of HTML, which allows you to see four different ‘windows’ simultaneously inside your main browser window. This viewing method will make configuration easier.
• press the JETset ‘Save’ button before moving from one area, e.g. ‘line’ to another area, e.g. ‘user’; see using JETset on page 246. This action will save your changes in volatile memory (RAM); the saving process is instantaneous. • to save your configuration changes to non-volatile memory, press the ‘Admin’ button and then select the ‘Save to FLASH’ button. The unit will spend a few seconds writing to FLASH memory, so we suggest you save to FLASH periodically (e.g.
• if you visit another URL (address on the World Wide Web) and then wish to return to JETset you can either: use the ‘JETset’ bookmark/favourite entry (the JETset home page), or use the ‘Go’ feature of your browser (if ‘JETset’ is listed - this is the JETset home page), or re-type the ip address of the unit in your ‘location’ field; e.g. http://192.101.34.211 the login page will be displayed; you will need to login again.
JETset program summary • compatible with Microsoft Internet Explorer® or Netscape Navigator®, both at version 3 or more recent versions • you can configure most Console Server parameters • access is restricted to the person with username ‘admin’ • although you can configure Console Server sessions, you cannot run them from JETset (sessions are character-based features suited to terminals) • you can use the ‘bookmark/add to favourites’ feature of your browser only with the login and home pages • y

Introduction This appendix contains solutions for problems that may arise while Console Server (the ‘unit’). - if you bought your unit from a registered Black Box Supplier, you must contact their Technical Support department; they are qualified to deal with your problem. - if you are a registered Black Box Supplier, and bought your unit from Black Box, please contact the Technical Support department of your nearest Black Box office.
•if your network is congested, subnet it with a bridge; however, bear in mind the recommendations in the previous paragraph. Host problems Cannot access a host by name •if using DNS or if DNS is required, ensure a nameserver is configured on your unit and is accessible (ping it). •if not using DNS, ensure the host is configured in the host table. Check access to the host by pinging it using the host’s IP address. Cannot access a host on a local network ensure: •the network address is correct.
Access to host lost after a few minutes •If the route to this host goes through routers, make sure those routers are all sending RIP packets across the networks. You see a message saying your host is in use. •delete your host as either, a DNS or WINS host, or a gateway, then retry the ‘delete host’ command/menu item. You may have configured your host as a DNS or WINS host, or a gateway. The connection fails when the user ‘ip_host’ parameter is set to 0.0.0.
Login problems User is waiting up to 60 seconds before login is accepted or denied other factors: authentication is set to ‘both’ or ‘RADIUS’. User has entered username and password, and has pressed key. • check RADIUS configuration of primary and secondary authentication/accounting hosts specified, and you have retry and timeout values greater than the default, the unit will be spending time trying each of these hosts and keeping the user waiting.
You have lost or don't know your password (as ‘admin’ user) • you must reset the unit to its factory default settings using the ‘reset’ switch on the rear panel. There is no procedure to access the unit without a password. at the remote end the client software locks up other factors: security (CHAP) is enabled on the line. • disable CHAP re-challenge parameter (challenge_interval) in the unit. Some PPP client software does not work when receiving CHAP re-challenges.
Problems with terminals see also: Login problems on page 255. The following section concerns problems with the appearance of data on your terminal screen: The unit logs me out after a few minutes •Change the idle timeout value set for the user. The idle timeout for all users is set to 300 seconds (5 minutes) by default, because the unit is designed for remote access connections (using SLIP or PPP). Corrupt data •check your line settings (baud rate, stop bits, etc.
Emergency recovery Problem: You have a unit already configured and, - you do know your password, but - have lost, misconfigured or don't know the IP address of the unit, and - you cannot obtain a login on any port (including the console port) The emergency recovery method is to use BOOTP (see Appendix F BOOTP). •Setup a host machine on your network to run BOOTP. Using the ethernet address of the unit (printed on the base of the product) BOOTP will assign the unit a known IP address.
