Did DNS partially break under Fedora 12 32-bit or x64 on your machine recently?
It was the strangest thing… DNS problems started for me last week, even though I had not done any software updates since the beginning of April. Machines using my caching nameserver would be fine, but some programs running locally would fail all name resolves (while others would succeed).
- yum install nss-mdns
- Change the hosts line in /etc/nsswitch.conf to “hosts: files mdns4_minimal dns”
And name resolution is back! 🙂
