Strange and long ping results, but no latency
Posted on 2007-07-19
(K)Ubuntu Feisty. I try to ping a server on my network, and it's really really slow.
me@me-laptop:~$ ping myserver
PING myserver.MYDOMAIN (192.168.1.2) 56(84) bytes of data.

--- myserver.MYDOMAIN ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 10037ms
rtt min/avg/max/mdev = 0.968/0.986/0.999/0.028 ms
Look at the times - all <1ms. But the total time was almost ten seconds.
nslookup is essentially instantaneous
This does not occur on any other computers, and throughput is fine. It does affect the loading of webpages, though.
I found somewhere that disabling IPv6 might help, but it doesn't seem to have made a difference.
