  I would say that it CAN'T work on Irix. :-))) But the networking is
probably slightly different under Irix. The problem is:

  "-r" causes the replies to be sent to the port 137 on the Linux box.
On the port 137 sits nmbd and listens for packets. So then there are fighting
two programs for incoming packets. I don't know what Linux does in this case
but apparently the packets are handed to nmbd which doesn't know what to
do with it and drops it. Probably under Irix the packets are always handed
to the last program which is listening on that port or something like it
(or hands it to ALL?!?) - simply it somehow works there...
