Description André Fettouhi 2011-06-24 09:39:53 UTC

I'm running Arch Linux (64 bit) with KDE 4.6.3 and since the introduction of the 2.6.38 series it is not possible for me to see my windows network. Neither using Dolphin, Konqueror or smb4k. I keep getting the error "no workgroups found in your local network". I turned off my firewall but I still can't see my network. Everything worked fine on 2.6.37 and earlier. The problem is still present in 2.6.39...

Are you using smbfs or cifs?

Comment 2 Steve French 2011-06-29 03:39:16 UTC

The workgroup browsing function in kde is handled through user space libraries not through the cifs (or smbfs) kernel file system drivers, so is more likely to be related to changes in the networking stack rather than the network file system driver.

You can do the rough equivalent at the command line (ie listing domains or workgroups) through the samba utility "nmblookup" which is probably easier to debug than the kde libraries.

If you find that the behavior of "nmblookup" has changed between kernel versions of 2.6.37 to 2.6.39, it should be easier to narrow down.

Comment 3 André Fettouhi 2011-06-29 07:31:18 UTC

Well nmblookup works under 2.6.39. If I do

nmblookup mywindowsdomain
querying mywindowsdomain on 192.168.1.255
192.168.1.6 mywindowsdomain<00>

Well nmblookup works under 2.6.39. If I do

nmblookup mywindowsdomain

192.168.1.6 mywindowsdomain<00>

Comment 5 André Fettouhi 2011-08-28 13:52:26 UTC

This works now with samba 3.6.0.

Comment 6 André Fettouhi 2012-02-16 21:33:20 UTC

This still doesn't work under the 3.2 kernel. I was a bit premature in comment #5.
