Cannot connect to the Nortel SNAS 4050 using Telnet or
SSH
Verify the current configuration
Connect with a console connection and check that Telnet or SSH access to the
Nortel SNAS 4050 is enabled. By default, remote connections to the Nortel
SNAS 4050 are disabled for security reasons. Enter the command
/cfg/sys/
adm/cur
to see whether remote access is enabled for Telnet or SSH.
Enable Telnet or SSH access
If your security policy affords enabling remote connections to the Nortel
SNAS 4050, enter the command
/cfg/sys/adm/telnet to enable Telnet
access, or the command
/cfg/sys/adm/ssh to enable SSH access. Apply your
configuration changes.
Check the Access List
If you find that Telnet or SSH access is enabled but you still cannot connect to the
Nortel SNAS 4050 using a Telnet or SSH client, check whether any hosts have
been added to the Access List. Enter the command
/cfg/sys/accesslist/
list
to view the current Access List.
>> Main# /cfg/sys/adm/cur
Collecting data, please wait...
Administrative Applications:
CLI idle timeout = 1h
Telnet CLI access = off
SSH CLI access = off
>> Main# /cfg/sys/adm/ssh
Current value: off
Allow SSH CLI access (on/off): on
