Configuring Subsystem Processes
Start the LISTNER process from a static or continuously available hometerm. If this
condition is not possible, (as is the case when a dynamic terminal such as a Multilan
dynamic window is used for startup operations), specify a local hometerm and IN and
OUT files or specify $ZHOME (a terminal simulator) or use the virtual hometerm
system, usually named $VHS.
You can enter the name of the PORTCONF file you have configured for the LISTNER
process to use. The default PORTCONF file is $SYSTEM.ZTCPIP.PORTCONF. After
modifying this file the LISTNER must be restarted. See PORTCONF File on page 3-40
for information on configuring the LISTNER process.
TELSERV Process
Once the NonStop TCP/IP process is started and the SUBNETs are configured, the
next step is to start your TELSERV process. TELSERV provides the facilities to bring
up terminal emulation (including TN6530) on the NonStop system. Refer to the Telserv
Guide to start your TELSERV process. (Brief examples are included in the TCPIPUP
files in Section 1, Configuration Quick Start. See also Appendix B, NonStop TCP/IP
Processes and Protocols.)
File Transfer Protocol (FTP)
The File Transfer Protocol (FTP, RFC 959) facilitates the transfer of files between
hosts. In the Guardian environment, the LISTNER process provides the FTP service.
Though a user can access FTP directly at a terminal, FTP is designed mainly for use
by programs. The objectives of FTP, as stated in RFC 959, are:
1. Promote the sharing of files (computer programs and/or data)
2. Encourage the indirect or implicit (through programs) use of remote computers
3. Shield a user from variations in file-storage systems among hosts
4. Transfer data reliably and efficiently
The FTP client allows you to transfer files to and from a remote host over a TCP
connection while working interactively at your terminal. In addition to transferring files,
you can choose and display directories on the remote host, delete and rename remote
files, and use tools such as macros to make your work easier and more efficient.
An FTP session is initiated by entering the FTP run command on your NonStop
system. FTP gives you a standard method for controlling data-transfer functions,
connection establishment, connection management, and data-transmission modes.
Note. The LISTNER process must be started by a user who has the user name
SUPER.SUPER and the user ID 255,255 in order for a remote FINGER client user to access
the information in the DOTPLAN and DOTPROJ files. Otherwise, the FINGER server cannot
locate the user's default subvolume in which these files are located. For more information on
the FINGER client and the DOTPLAN and DOTPROJ files, refer to the TCP/IP Applications
and Utilities User Guide.
