Package: wvdial
Version: 1.54.0-1
Severity: serious

Hi there,

I played around a bit with my network connections. I have a pcmcia nic
connected to my home network with dhcp running on my fileserver. I used
webmin-wvdial to connect to the internet via a mobile phone via irda. I am
not sure when, but I removed the nic (which is managed by ifplugd, a debian
package to manage mobile nics) somewhere in the process to see if the
connection was really made over the mobile.

After I was done playing around I reinserted the nic and internet access
didn't come back automagically. So I did the ifup eth0 and got an error
message telling me that /etc/resolv.conf was no longer linked to
/etc/resolvconf/run/resolv.conf. /etc/resolv.conf contained the dns servers
supplied by the server I connected to via wvdial, while
/etc/resolvconf/run/resolv.conf cotained the addresses of the dns servers
supplied by my dhcp.

I have to admit that I really stress tested the thing probabley removing and
reinserting the nic, which always drives ifplugd crazy, but under no
circumstances should wvdial ever delete the symbolic link and put up its own
/etc/resolv.conf. I am still not sure what or when it happened, so ifplugd
could still be the culprit, but the dns servers from wvdial were in
/etc/resolv.conf, which suggests that it was wvdial.

I am sorry that I can't provde further details at the moment, but since this
is such a severe bug (breaks all net access) I thought I should respond
ASAP.

Thanks,

Malte Schmidt-Tychsen
