Original submission:

I am using Linux Debian 3.1 and i have set my interface file with:

iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1

If I unplug the network cable and try to open MC, MC doesn't open. 
If I comment field gateway in interfaces file and keep the cable 
network unpluged, then MC open normally.
If I plug the cable and uncomment field gateway, the MC open 
normally too.

i think that's some call to gethostbyname(). if the route is known 
to be broken, it fails immediately. if the cable is pulled, it has 
to time out.

I couldn't reproduce on FC3 with latest cvs version.

Would you mind providing a strace of MC hanging ? You could do so 
by issuing the following command:

strace -o /tmp/mc.strace /usr/bin/mc

Replace /usr/bin/mc with the full path to the mc binary.

Ping ?

The mc hangs on startup at line 284 in the attached file from me. 
Please look more info about this at the comment of that file.
Maybe the two situation are from the same problem.
Actually I don't know what changed in my system, because I see this 
problem 2 days ago only. I think I just updated the system with 
apt-get.

It seems it tries to connect to the router at port 53 several 
times, which makes the hang. After that when the mc is stared, 
everything is ok.

The problem is due to the outdated samba library included with MC.
You can find out more here:

We actually don't need info any more since we know what's the cause 
of the hang - changing the status to None.

ohhh.... commenting out the eth0 interface from the smb.conf helps... thank you very much!

Should we close this as a duplicate of bug 5142 then?

Maybe this goes a bit too far fow now, but I think the smb client stuff should be moved out to a separate process, mounted via 9P, and mc itself should handle not block on vfs hangs (multithreaded ?).
