    Please be a bit more specific.
    Do you ssh as a regular user or as root?

    Try the following commands:
    ssh to Suse 9.3
    'mount' You want to see what is mounted.
    'df' This will stat your devices.

    There are a number of reasons that listing files in root can cause a system
    to appear to hang. If you are trying to mount an NFS exported directory,
    and it is not available (such as /foo where /foo is the mount point).

    When you are in /home, an 'ls' command is only concerned with /home. But, if
    you are in the root directory, the 'ls' command stats the top level of
    everything in the root directory, so if /foo is the culprit, ls will hand
    when trying to stat it. Same with Konqueror. If you have similar mounts in
    freenx you would have the same situation.

    Ran into a similar thing on SLES9 the other day. We were changing the IP
    addresses of all the systems prior to moving them to another facility.
    Apparently, Tim must have fumble fingered something in YaST causing YaST to
    hang. I brought the system down to single user mode, and did some things by
    hand, but there is a very large home file system that is exported to a
    number of systems, and that was causing the hang.
