              I printed the data you asked for and made no changes to
              VAX because they looked OK to me.  TCPIP SHOW ROUTE looped
              and produced no output.<br>

    The only weird thing I see is there is a mismatch between the
    netmasks you assigned in the linux side (255.255.255.0) and the VAX
    side (255.0.0.0). That COULD be the cause of the PING timeout. The
    cause for the SHOW ROUTE is that it tries to get the names
    associated to the addresses, so it does a DNS call which times out,
    hence the hang you are observing. Try to change the netmask to
    255.0.0.0 in the linux side and tell us what happens. It _should_
    work, unless you have some sort of firewall at the linux side
    preventing the ping succeeding.<br>
