Question

I want to to check a Nortel Router by running ./script:

#!/bin/ksh
print "IP:"
read ip;
ping ${ip};
ssh -l default ${ip} "sho mod; en; sho int; sho node-e; sho node-a";

I can ssh normaly with
ssh -l [user] [ip].

But not with
ssh -l [user] [ip] ‘[cmd1], [cmd2]’ it says automatically “Conection to [ip] closed.”

Answer 1

There’s application called expect which can do that kind of interaction / terminal simulation for you. Otherwise, you could write a script using fabric or even straight in python using paramiko

Running commands this way would be better of course, but if your router doesn’t accept commands this way, you’ll need to simulate the standard connection.
