Normally I would expect someone running a non-standard server to know about it... What's in your /etc/rc.d/init.d directory? Anything relating to sshd or sshd? If you'd got an initscript there, try figuring out which package (if any) it came from: $ cd /etc/rc.d/init.d $ rpm -qf *ssh* > Just a little question.

As Jeff answered earlier, this is how I (and many other people) distinguish commands that can or should be run as a regular user, and those that should be run as root. Running netstat as root provides extra information compared with running it as a regular user. Paul. -- Paul Howarth <paul@xxxxxxxxxxxx>
