Remote Security Officer
The Remote Security Officer (RSO) feature enables a remote user to connect to a
router via Telnet from an authorised IP address, and login using a login name
with SECURITY OFFICER privilege as if the user were at a terminal connected
directly to the router. By default the Remote Security Officer feature is disabled.
The RSO feature can be enabled or disabled using the commands:
ENABLE USER RSO
DISABLE USER RSO
Authorised IP addresses can added or deleted with the command:
ADD USER RSO IP=ipadd [MASK=ipadd]
DELETE USER RSO IP=ipadd
The MASK parameter allows a range of IP addresses to be added. The current
state of the RSO feature and the list of authorised IP addresses can be displayed
using the command:
SHOW USER RSO
All RSO commands require SECURITY OFFICER privilege and therefore must
be executed from a terminal directly attached to the router or from a Telnet
session originating from a previously configured RSO address. RSO must be
enabled, and the first address added, from a terminal directly attached to the
router. If RSO is disabled (either from a terminal or a Telnet session) it can only
be re-enabled from a terminal directly attached to the router.
Once RSO has been enabled and configured with one or more IP addresses, a
Telnet session from one of the authorised addresses will be able to login as a
user with SECURITY OFFICER privilege.
