"su root" fails when I connect with normal user thru SSH


Hi everyone.
I'm running a Trustix 2.2 (fedora based) machine at work and I need to remote connect on it from outside. So I configures ssh to do the job.
But, if I connect using a normal user (from the users group), the machine does not allow me to "su" or "su root" - the error message is "incorrect password".
If I set the "enable root login" line to "yes" in sshd_config, I am able to ssh straight with root, but I can't "su" with that line set to "yes" or "no" either.
I am absolutely sure the root password I am providing IS the correct one (since I can use it locally or if I ssh with root).
Sometimes the system won't allow me to "su" even locally - would that be just a system bug or are there any settings that I should be aware of, at least for ssh? I did updated all my installed packages just today (the problem was even before I did that and it's still present).

Thanks,
Alin Faur.

su -
su - <user>

Try logging in with root (eg: root@your.server.ip) and changing the password with the passwd command. While you're in as root, consider the following.

Just a tip for the future: I recommend putting your normal user into the sudoers file and using sudo instead of switching back and forth with su.

In some distro, to use "su", your user have to be in the wheel group. Take a look at /etc/group
