I have been having some REALLY wierd problems using Domain services in
an internet.

The problem (a rather simplified diagram) :


                     merlin (3500)
                    /     \
              RING  \     /
                     \   /
                     zaphod (10000 running rtsvc)
                       |
     ------------------------------------------------------------
      ETHERNET                              |
                                          lindon (4500)

1) rtsvc is running on the 10000.

2) when I log onto lindon and lcnode I can see both lindon and zaphod.

3) I can cd to //merlin ok, so I guess rtsvc is ok on zaphod.

4) when I cd to etc on merlin and do an 'ls' I get a full directory
   listing ok.

5) BUT, when I do an 'ls p*' to list all files beginning with p, the whole
   thing locks up on me.

   if I have another pad open at the same time continually pinging merlin
   using TCP/IP packets, the instant I type in the 'ls p*' the pinging
   halts.

   also, more often than not, when I regain control again, 'lcnode' will
   only see lindon and will not find zaphod.

what on earth is different between doing an 'ls' and an 'ls p*' ????? Are
different packet sizes used for any obscure reason ??? (lindon is connected
to the ethernet using thinwire via a 3Com multiport repeater)

could it be the VME ethernet card in the 10000 ????

I'm obviously at a loss to explain this behaviour so I'd luv whatever clues
I can get :-)
