Black Box Value-Line and Advanced Console Servers, LES1332A System Services, Service Access

3.4System 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.

3.4.1Service 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.
