If you need to run a single command (as in your post), you can remove the separate "su" line, and try: 
$ssh->system("su -c 'show status' admin");

Of course, you will need to remove the corresponding "exit", because this will run the command, and exit automatically.

      Hmmm . FreeBSD "su" interprets the "-c" option as "class". , so it is useless for your purpose.

      I dont see any good options. It looks like you will have to install "sudo" if it is not already installed on the target system.

      For instructions on sudo install see What's the sudo equivalent for FreeBSD?.

        FreeBSD "su" interprets the "-c" option as "class".

        Explicitly invoking sh should do the trick: su admin sh -c 'show status'

        Reading the fine manual suggests that the problem of "-c" could also be the order of arguments: su -c 'show status' admin has "-c" in front of the login parameter. Moving "-c" after the login parameter, as shown in the third example, should work: su admin -c 'show status'.

        Please note: everything posted here is untested, I currently have no FreeBSD machine to test.
