Public bug reported:
Binary package hint: gvfs-backends
Very similar to Bug #191547 (most of this description is copied from
there). But this time it is about hardy and gvfs.
Samba browsing works like a charm after login. gvfs sees all samba
workgroups and servers:
$ gvfs-ls smb:///
E-WARE
MUNKACSOPORT
VIRTUAL
But after switching between wired and wireless networks, gvfs no longer
sees any samba workgroups or shares.
$ gvfs-ls smb:///
[no output]
After some digging with wireshark, I noticed that the problem is that gvfs
sends the NMB name lookup requests to the wrong broadcast address.
For example:
1. Let the wired network be: 192.168.5.0/24 (broadcast 192.168.5.255)
2. Let the wireless network be: 192.168.6.0/24 (broadcast 192.168.6.255)
Let's suppose that the wired connection was active when I started my gnome
session. Then after switching to the wireless connection gvfs still keeps
sending NMB name lookup queries to 192.168.5.255 which is WRONG.
Workaround:
$ killall gvfsd-smb-browse
Putting the above line in some if-up/if-down script makes the problem go
away.
$ dpkg -l | grep gvfs| cat
