hi all,
i have a Samba version 3.2.5 server running in a debian 5.0.8 (a little
old, i know...).
the network setup is:
-one local office using samba
-one remote office (we call it cberg) using samba remotely over a vpn
(linksys-cisco)
Here's you problem don't use cisco.
-another remote office (we call it colon) using samba remotely over a vpn
(linksys-cisco)
Another problem
the local office and colon office are working fine
the remote office cberg WAS working fine, until they changed internet
supplier...
now, the problem is that i can browse the shares, but when i want to open a
file, i get an error (after some time) saying something like: "The
specified network name is no longer available".
since then, i have been talking with the network admin about the problem. i
suppose that the problem was caused by the change of the internet supplier
(i was pointing to some MTU problem, since it is a wireless connection). so
i changed the mtu size of the linksys (in the remote office), but the
problem is still there.
i checked connectivity of the two hosts and it is working ok.
i have captured traffic in both ends, but my knowledge is a little limited
here, so if you want i can provide them in some place in the internets.
smbstatus shows the PC connected ("home" machine), among others:

which could be the problem?
can anybody help me debug this?
I would recommend using wireshark to capture the packets and verify
proper routing, also make sure that samba is starting after the VPN link
is up so it's listening on the proper interface.
That's my humble guess.
Cheers.
thanks in advance!
