Any idea or tips on that one ?

I would do this using sudo instead of su.

1. create user1 to the remote machine

2. define commands that user1 can execute as root to the /etc/sudoers
<example entry to the sudoers file>
user1 ALL=NOPASSWD:/sbin/iptables
</example>

Unfortunatly, I am not allowed to use sudo ...


3. execute command as root using ssh
#ssh user1@xxxxxxx "sudo -u root /sbin/iptables -L -n"
<no root password needed>

4. to execute ssh without user1's password, create RSA/DSA-keys for you
and store public part to the /home/user1/.ssh/authorized_keys to the
foo.bar machine

Yes, I'll do that for preventing the user1 password prompt.

I will try to use "-t" with the ssh command as suggested by Darren on an
other post.
"su" seems to need a real pseudo-tty and the "-t" force the allocation of
a pseudo-tty not allocated by default when ssh is used force launching
remote command.

Thank you for the complete answer guys.

Gaga.

It works great !

Thank you,
