Select the System: Services option, then select/deselect for the service to be enabled/disabled.
The following access protocol options are available:
HTTPS This ensures secure browser access to all the Management Console menus. It also
allows appropriately configured Users secure browser access to selected
Management Console Manage menus. If you enable HTTPS, the Administrator will be
able to use a secure browser connection to the Console server’s Management
Console. For information on certificate and user client software configuration, refer
to Chapter 9Authentication. By default, HTTPS is enabled, and we recommend that
that you only use HTTPS access if the console server will be managed over any public
network (for example, the Internet).
HTTP By default HTTP is disabled. We recommend that the HTTP service remain disabled if
the console server will be remotely accessed over the Internet.
Telnet This gives the Administrator Telnet access to the system command line shell (Linux
commands). This may be suitable for a local direct connection over a management
LAN. By default, Telnet is disabled. We recommend that this service remain disabled
if you will remotely administer the console server.
SSH This service provides secure SSH access to the Linux command line shell. We
recommend that you choose SSH as the protocol where the Administrator connects
to the console server over the Internet or any other public network. This will provide
authenticated communications between the SSH client program on the remote
PC/workstation and the SSH sever in the console server. By default SSH is enabled.
For more information on SSH configuration refer Chapter 9Authentication.
You can configure related service options at this stage:
SNMP This will enable netsnmp in the console server, which will keep a remote log of all
posted information. SNMP is disabled by default. This SNMP service is only available
in rackmount models. To modify the default SNMP settings, the Administrator must
make the edits at the command line as described in Chapter 15Advanced
Configuration.
TFTP This service will set up the default tftp server on the USB flash card (and is relevant
to LES1208A, LES1216A and LES1248A console servers only). This server can be used
to store config files, and maintain access and transaction logs, etc.
Ping This allows the console server to respond to incoming ICMP echo requests. Ping is
enabled by default. For security reasons, you should disable this service after initial
configuration.
And there are some serial port access parameters that you can configure on this menu:
Base The console server uses specific default ranges for the TCP/IP ports for the various
access services that Users and Administrators can use to access devices attached to
serial ports (as covered in Chapter 4Configuring Serial Ports). The Administrator
can also set alternate ranges for these services, and these secondary ports will then
be used in addition to the defaults.
The default TCP/IP base port address for telnet access is 2000, and the range for
telnet is IP Address: Port (2000 + serial port #) i.e. 2001 2048. If the Administrator
