Problems with Samba and/or Sundance Ehternet Driver

["Paul Galbraith" <paul@paulgalbraith.net>]

I'm having a lot problems getting Samba running on my deb 3.0 machine.  I
suspect the problem is really a problem with the sundance ethernet driver,
but that's a fairly random guess.

The main diagnostic symptoms are numerous read failures in the samba log
file, such as:

  [2003/07/15 15:29:33, 0] lib/util_sock.c:read_data(436)
    read_data: read failure for 4. Error = Connection reset by peer

These occur whenever I try to browse or use the file share.  From a WinXP
client, I cannot even connect to the share...I just get a "cannot find
resource" error (accompanied my many of the above read failures in the samba
log) after a delay of several minutes.  From a WinME client, I can browse
the share, but almost any attempt to transfer files results in an error and
many more of the above messages in the samba log.

Here is my smb.conf:

[global]
        workgroup = arda
        encrypt passwords = yes
        security = share

[pub]
        path = /home/samba
        public = yes
        browseable = yes
        writable = yes
        guest ok = yes
        guest only = yes

As I said, I suspect it's a problem with my ethernet driver (sundance.o) or
else my NIC (D-Link DFE-530TXS) is bad.  (I've seen the above problems when
using either of the 2.2.20 or 2.4.18 kernels.)  Since I haven't seen any
other networking problems, either of these conclusions seems a little
suspect, but I can't think what else could be the problem.  Is there a good
way to test my network adapter and verify that it (and the driver) are
working properly?

Thanks to anyone who can offer some suggestions!
