[Samba] Samba winbindd: "Invalid request size received" problem

[Moshe Aelion]

Hi experts - I hope you can help me.

I am trying to resolve Windows host names (aka Netbios names, aka "UNC names) from a Linux box. 
I have added "dns wins" to the "hosts" line at the nsswitch configuration file: /etc/nsswitch.conf, and installed samba 3.2.2 and ran winbindd -D". 

Now, when I go: "wbinfo -N venus" (where venus is a Windows UNC pc host name on the LAN), it responds: "192.168.0.12" (which is venus' IP address). But, when I go: "ping venus", it says: "ping: bad address: venus", and in the log file: ffp/var/log/samba/log.winbindd
it says: "winbindd/winbindd.c:request_len_recv(616)
request_len_recv: Invalid request size received: 1844 (expected 2096)"

When I try to copy a file from the Windows PC to the Linux box, going:
rsync -v "venus:e/my Documents/Temp/a.txt" . 
(where a.txt is the file I'd like to copy), it says: "ssh: Could not resolve hostname venus: Name or service not known", and in: ffp/var/log/samba/log.winbindd it says again:
"winbindd/winbindd.c:request_len_recv(616)
request_len_recv: Invalid request size received: 1844 (expected 2096)".

More info: I am running a Linux system whose kernel version is: "2.6.12.6-arm1". It's a D-Link DNS-323 NAS box with an ARM processor.
I have stopped and restarted winbindd.

Your help will be appreciated. Thanks in advance - Gail
