    I'm using SSH 3.4 on a Linux server for a home network. Several times
    in the past couple months, I've had to reboot a Windows PC that was
    connected to the server via SSH, and this has left an orphan
    connection that appears to stay open forever. (I've since learned of
    the ClientAliveInterval and ClientAliveCountMax options in
    /etc/ssh/sshd_config.)

    The problem is, the server thinks there are five current users when,
    in fact, there is only one. 'who' returns four users with pts/?
    ports, two of which are over a month old.

    I cannot find multiple instances of the ssh deamon running. 'ps -aux |
    grep ssh' returns one instance.

    I have restarted sshd, but that doesn't get rid of the dead
    connections.

    Is there any way to convince the Linux box that there is only one
    user? I've read the man pages for ssh and sshd, hoping for a
    command-line option that would do the trick, but haven't found
    anything.

    Thanks in advance for any help.
