Samba to Dave 2.5

[John Hester]

I'm having a problem with folders shared from Samba 2.0.5a dissappearing
and reappearing on a Mac running Dave 2.5.  I had the same problem with
Dave 2.1 and hoped the upgrade to 2.5 would help.  The 2 Samba servers
are on a separate subnet on which they are the only machines.  One Samba
server is set as the local master browser and both use an NT server on
the same subnet as the Mac as their wins server.  I have the Samba
'remote announce' option set to broadcast to the Mac/NT subnet as well
as announcing directly to the Mac and the wins server (I've tried every
possible combination here).  I've also tried a number of socket option
settings, none of which made any noticable difference.  Currently the
only socket option is TCP_NODELAY.  I used a Samba server on the same
subnet as the Mac for about a year with no problems, so I'm reasonably
sure the problem has something to do with the current Samba servers
being on a remote subnet.  I have no problem maintaining stable
connections from any windows machines to the Samba servers or from the
Mac to an NT server.  When I ping the Samba servers from the Mac I get 0
packet loss.  Here's a simple diagram of the network:

Samba   Samba          NT wins server
    \          /                           \
      \      /                               \
     router--------------------router-----multiple Winxx desktops
                                             /
                                           /
                                        Mac

The Samba servers are SGIs running IRIX 6.5.5.
