nautilus use the wrong broadcast address to search for smb servers

[Matthieu Patou]

My computer is moving between two LANs with both server exporting SMB/CIFS shares.

Last time I booted and logged on my computer it was in LAN 10.6.0.0/26.

Today I tried to use nautilus to browse share in the 192.168.10.0/24 lan and it failed to show my samba server at 192.168.10.222.

Tracing while clicking in "Windows Network" icon in nautilus produced this trace:

mat@ares:/var$ sudo tcpdump -i wlan0 -n not port 22
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

It's clear that Nautilus is trying to do a broadcast on another and of course it won't be able to find any resources this way.

Can you still reproduce this issue on 12.04 or better yet on 13.10/14.04?
