impossible to connect to DNS
Hello,
I have been using Debian testing on my laptop for a while now, and
networking-wise everything went smooth until today it all of a sudden
refused to connect to the DNS server and therefore refused to connect
to anything else unless provided with the IP address.
For example, I can set up IP adresses with the corresponding names in
/etc/hosts and it connects just fine (this is what I did for
ftp.fr.debian.org) but it for some reason cannot connect to the dns
server. The
server itself is fine because all the other machines on my LAN use it
no problem.
When trying to probe with nslookup it gave this error:
nslookup: undefined symbol: isc_net_pton
I therefore thought I got hacked, also keeping in mind the fact that I
have not done a dist-upgrade for about two months because it kept
trying to wipe lyx and I absolutely needed lyx. So maybe there was some
security bug that got fixed but that I was exposed to because I didn't
upgrade.
So I did
apt-get update
apt-get dist-upgrade
this took a while because there were about 300 packages to install or upgrade. Then
apt-get clean
apt-get install --reinstall [all packages on which nslookup depends, meaning all the libraries it links to]
There's maybe about 9 of them, the most notable of which is libc6.
But the same thing happens. No DNS, except now I don't get the
weird undefined symbol error anymore. ping just gives unknown host
unless you give it an IP address
Anybody have any idea what could be wrong?
I have also tried purging and reinstalling the resolvconf package. No change.
