6.5.2.9 Outgoing SSH Connections
To form an SSH connection to another host from the SCS, enter the ssh command followed by the desired
host's hostname or IP address.
The first time you SSH to a remote host from the SCS, the SCS notes that the host is not recognized, but
permits the connection. If you are not the privileged user, you will be allowed to use the host's key for the
current session, but the key will not be permanently saved in the list of known hosts.

Local_9> ssh athena
%Info: The authenticity of host 'athena' can't be established.
RSA key fingerprint is 5f:d0:d7:69:39:d1:ca:fb:71:eb:g4:33:b1:ba:8c:e9.
%Warning: Failed to add the host to the list of known hosts

If you are the privileged user, the host's key is permanently added to the table of known hosts (stored in
/flash/ssh/known_hosts).

Local_9>> ssh athena
%Info: The authenticity of host 'athena' can't be established.
RSA key fingerprint is 5f:d0:d7:69:39:d1:ca:fb:71:eb:g4:33:b1:ba:8c:e9.
%Warning: Added 'athena' (RSA) to the list of known hosts.
mary@athena's password:
For each following connection between the SCS and that host, the host's key will be compared to that stored
in the known host table. If the key is authentic, the connection will automatically proceed to user
authentication.
If the key has changed, you will receive a warning and a brief list of possible explanations including a
possible man-in-the-middle attack. To successfully connect, erase that host's public key from the
known_hosts file on the SCS, then attempt the connection again. The SCS will note that the host is not
recognized.
