How to run command on remote server?
Hi

below is the script but it is not showing me the o/p of B machine but instead showing me A machine o/p every time.


Code:
#!/bin/bash
for i in `cat IP`
do
ssh root@$i
hostname
mt -t /dev/nst0 status
echo done
done

Regards,
Scriptor

Or perhaps:-
Code:
while read i
do
   ssh root@$i "hostname;mt -t /dev/nst0 status;echo done" < /dev/null
done < IP

Understandable, as nested single quotes usually don't.
Did you try rbatte1's proposal? To what avail?

the problem in this code is it is not accepting the password.
