I still get the same when using that method:

[chris@x] while read HOST; do ssh $HOST; done <dbs_group
Pseudo-terminal will not be allocated because stdin is not a terminal....

This might be a simple question, but I can't find the answer out there anywhere. I'm trying to write a loop to SSH to a server for me to then copy/paste some commands in. Once I'm done, I type 'exit'...
