Detailed Command
Descriptions
accessconfig
This command starts an interactive shell script that will allow the root user to configure limitation of
telnet
,
ssh
and
snmp
access to the Tempus LX. By default, the unit is configured to allow access
by all users. If you need to limit
telnet
,
ssh
or
snmp
access, e.g. for security reasons, you must run
this script as root from either the RS-232 serial I/O port or from a
telnet
or
ssh
session.
This script modifies these files:
/etc/hosts.allow
and
/etc/hosts.deny
. These are non-volatilely stored
in the FLASH disk /boot/etc directory. You must re-boot the Tempus LX after running this script for
the changes to take effect.
Set:
accessconfig
Tempus LX response: Interactive shell script is started.
