[Solved] Using SSH in bash script
Hello,

I am writing a script that has to log in to X number of servers over a full C class range.

I am only keyed on a certain number of these servers and this can change from time to time.

The part of my script that deals with this is

Code:
for i in $(cat $server_list); do
       ssh  root@$i "Run commands!"
done

If I connect to a server that I am not keyed on I get a password prompt. Is there a way (return code?) that I can detect this and then move on to the next server? Or does anyone know a way I can add some sort of timeout to the script?

Regards,
Colin

if anyone is interested
