I have just upgraded from 10.04 to 12.04. I didn't notice the problem at first. But when installing horde with the pear installer it failed to download all of the packages.
So I did a little hunting and realised not all hosts are reachable:
root@sub:~# ping google.com PING google.com (220.127.116.11) 56(84) bytes of data. 64 bytes from wb-in-f113.1e100.net (18.104.22.168): icmp_req=1 ttl=51 time=11.1 ms 64 bytes from wb-in-f113.1e100.net (22.214.171.124): icmp_req=2 ttl=51 time=11.1 ms --- google.com ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1002ms rtt min/avg/max/mdev = 11.166/11.177/11.188/0.011 ms
root@sub:~# ping cnn.com PING cnn.com (126.96.36.199) 56(84) bytes of data. --- cnn.com ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1006ms
At first I could not reach any hosts so I added
nameserver 188.8.131.52 to my
/etc/resolv.conf file. This was blank after the upgrade.
So why can i not ping ccn.com and other random domains but I can google.com?
