For a 25-bit netmask (, you want a broadcast address

Otherwise this sounds suspiciously like an ARP botch, ad does your

Can you try a arp -an (or netstat -nr) from the console of the
afflicted machine during the freeze? I am especially curious to hear
wthat difference it makes if you leave a

      ping -v <correct broadcast address>
running on (a) the server, (b) the client end of the connection.

I cant place the 5sec period.  Maybe the automedia FSM has a bug, in
which case the 1Hz ping is unlikely to cause any difference.

Are these machiens connected via a switch/router, or a dumb hub?
