Your
Code:
exec <$1

redirects all script input from whatever $1 is. Thus, any programs started by this script will also be redirected to whatever $1 is. Your starting ssh in interactive mode, which shouldn't take input from a non-terminal.

You don't need this exec line:
Code:
cat $1 |
while read line 
do
ssh ....
done

Or maybe you want to use ssh to execute a command and not run interactively. Is that the case?

Still after running the command this dispalys
