FC11 - DNS stopped working by itself
I switched my FC11 system off yesterday. Turning it on this morning, NO domain names can be resolved anymore.
I can ping IP adresses directly, and even get to them in FireFox if I type the IP address. However, typing any domain name at all fails. I cannot ping or SSH to any domain name, but as soon as I enter an IP, it works. I can ping the DNS server by IP that is set in my /etc/resolv.conf
I checked on an XP system using the same DNS server set in /etc/resolv.conf (which can also be pinged on IP from my FC11 system), on the same connection from the same ISP, and it works.
E. g. without touching anything at all (and all updates are turned off) my FC11 system has stopped resolving domain names.
I'm running 32bit FC11. The system has been working fine for more than 2 years.
So it has spontaneously stopped doing DNS when I enter a domain name. Where can I start looking?
