Hi all,
I remember a discussion here about slow DNS for P&T. I am experiencing
something similar with Visual Online, although I cannot say for sure if
it's their problem or mine.
This is one sample query caught by Ethereal:
Time Source Destination Protocol Info
24.107756 192.168.1.8 192.168.1.1 DNS
Standard query A
www.athome.lu
29.115471 192.168.1.8 192.168.1.1 DNS
Standard query A
www.athome.lu
34.125519 192.168.1.8 192.168.1.1 DNS
Standard query A
www.athome.lu
39.135464 192.168.1.8 192.168.1.1 DNS
Standard query A
www.athome.lu
39.165492 192.168.1.1 192.168.1.8 DNS
Standard query response A 80.92.67.138
So it means it took 15 seconds and 3 retransmissions for a DNS query to
get an answer. BTW, 192.168.1.8 is the PC, and 192.168.1.1 is the router
which forwards to VO's DNS.
This behavious is not systematic, but fairly regular (and extremely
annoying). There's 3 candidates:
-1- the PC
here's what resolv.conf says:
nameserver 192.168.1.1
-2- the router
I am unable to find anything in the logs, and I haven't changed anything
on that level except disable the RIP protocol.
-3- the DNS
not sure which one I use, as the router gets this information somehow
from VO - however, I have been unable to find any DNS specific setting
in the router. In the "LAN" tab, it says 0.0.0.0 for both the primary
and the secondary DNS server.
Any clues appreciated.
