BASH SSH Redirect on Fail

Question

I have a BASH script that logs in to multiple servers and runs a series of commands. Occasionally I'll have instances where a server is unavailable (regular maintenance, etc). How can I exit out of the SSH session cleanly without passing an error like this?:

bash-3.2$ ssh myserver3
Disconnecting: Bad packet length.

Are you asking how you could avoid the message going to stderr? — Oliver Charlesworth, Sep 27 '14 at 12:54

You may be looking for -q option:

ssh -q user@host

And you can check the return code $? afterwards.

From man bash:

-q

Quiet mode. Causes all warning and diagnostic messages to be suppressed

You can find more info about this topic in How to create a bash script to check the SSH connection?.
