i'm not sure when it started, but my dns is officially flakey. sometimes
sites just won't resolve, and others, it'll take a very long time. my first
thought was of course: gibbled dns server(s). but no one else in the office
is having the same problem.
so then i tried a few simple tests:
(2004-10-05 12:13:51) $ host forums.gentoo.org
forums.gentoo.org has address 140.211.166.164
(2004-10-05 12:13:57) $ host forums.gentoo.org
forums.gentoo.org has address 140.211.166.164
(2004-10-05 12:13:57) $
the first request took 6 seconds (short compared to some others) but the
second not even a second. but this isn't the big problem. the delay is most
noticeable when using a program like konqueror to retrieve a page. it
literally can take about 30seconds.
so wondering what was going on, i ran ngrep. it took 17seconds to decide
www.google.ca didn't exist, and after a refresh, another 10 seconds to load
the page (with a dead image). here's what ngrep said:
