Descriptions
accessconfig
This command starts an interactive script that will allow the root user to configure access limitation
via
telnet

ssh
and
snmp
to Meridian II. 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

changes to take effect.
