Today I find a curious case, SL has a strange behavior with dns. My terminal command:
[root@intern ~]# cat /etc/resolv.conf nameserver 8.8.8.8 nameserver 8.8.4.4 [root@intern ~]# ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=44 time=62.6 ms 64 bytes from 8.8.8.8: icmp_seq=2 ttl=44 time=74.5 ms 64 bytes from 8.8.8.8: icmp_seq=3 ttl=44 time=42.6 ms 64 bytes from 8.8.8.8: icmp_seq=4 ttl=44 time=66.9 ms [root@intern ~]# ping priona.net ping: unknown host priona.net [root@intern ~]# nslookup priona.net Server: 8.8.8.8 Address: 8.8.8.8#53 Non-authoritative answer: Name: priona.net Address: 146.255.96.119 [root@intern ~]# host prina.net prina.net has address 72.47.224.79 prina.net mail is handled by 10 mail.prina.net.

Any idea?
