Comment 33 for bug 406466

The NAS that I am using is an Addonics NASU2 NAS adapter with a 1 GB disk attached. This worked fine under Ubuntu 9.04 and 8.10. I'm attaching two output files from the tcpdump command that you requested - the file broken-cifs-9.10-wvh.pcap is packet capture info from my fully updated 9.10 system (uname -a output: Linux u910.vonhagen.org 2.6.31-13-generic #44-Ubuntu SMP Sat Oct 10 15:27:14 UTC 2009 x86_64 GNU/Linux). The commands that I executed during this capture session were:

mount /mnt/NAS
ls /mnt/NAS
cd /mnt/NAS/Music
ls

No files or directories were shown by either of the ls commands. The Music directory was a directory that I knew to be there. My /etc/fstab entry for this device is:

//192.168.6.33/public /mnt/NAS cifs user=WVH/wvh%password,uid=1000,noauto 0 0

The second tcpdump output file (broken-cifs-9.04-wvh.pcap) was produced by using the same tcpdump command on a netbook running Ubuntu 9.04. I executed the same commands after initiating the packet capture. The /etc/fstab entry is identical. That system (32 bit) is running kernel version 2.6.28-15, and is wireless. After the mount on that system, I can see all files, directories, etc - just like the good old days!

Hope this helps. I'll be glad to capture any other data that you'd like, as well as any other side-by-side comparisons.
