Server User Manual

3.4 System Services
The Administrator can access and configure the console server (and connected devices) using a range of
access protocols/services and for each such access, the particular service must be running with access
through the firewall enabled. Service Access specifies which access protocols/services can be used to
access the console server (and connected serial ports).
By default HTTP, HTTPS, Telnet and SSH services are running, and these services are enabled on all
network interfaces. However, again by default, only HTTPS and SSH access to the console server is
enabled, while HTTP and Telnet access is disabled.
For other services, such as SNMP/Nagios NRPE/NUT, the service must first be started on the relevant
network interface using Service Settings. Then the Services Access can be set to allow or block access.
3.4.1 Service Access
Service Access specifies which access protocols/services can be used to access the console server (and
connected serial ports). To change the access settings:
Select the Service Access tab on the System: Services page. This will displays the services
currently enabled for the console server’s network interfaces. Depending on the particular
console server model the interfaces displayed may include :
Network interface (for the principal Ethernet connection)
Dial out (V90 and cellular modem)
Dial in (internal or external V90 modem)
OoB Failover (second Ethernet connections)
VPN (IPSec or Open VPN connection over any network interface)
Check/uncheck for each network which service access is to be enabled /disabled
In the example shown below local administrators on local Network Interface LAN have HTTP and Telnet
and HTTPS and SSH access to the console server (and attached serial consoles). However while remote
administrators using Dial In only can access using the console server using HTTPS and SSH, they can
Telnet access attached serial consoles.
