Howdy all, I think that this is related to lookupd and is therefor on topic here
but I may be wrong so any diagnostic help would be helpful. The
short of it is that a huge amount of my http traffic is getting
routed to slashdot's IP when it should not be. I will try to be
succinct but I don't really know what is relevant so I can only cut
so much. This all started about two weeks ago on Sunday when our office was
banned from Slashdot (there are lots of geeks here and it did cause
some distress.) After contacting them they said that we were banned
for using a bot or spidering the site, there were 3000 hits in an
hour's time. So we went about trying to figure out what windows box
had a virus or linux box had been rooted, well we attached a packet
sniffer right before the NAT box to find the culprit. Lo an behold
it was my mac. The wacky thing is that it looks like in Safari when loading the RSS
view (I have like 15 rss feeds I read in the combined view) the http
traffic was all going to slashdot and not where it belonged. For
instance an image obviously belonging to the boingboing.net feed was
requested from slashdot's http server. Later in analyzing this I
used dig to look up the IPs and they were not at all similar (so it
is not a case of the same machine hosting different sites). Now I have always thought the web was kind of flakey and so I don't
even blink when an image link is broken or the like. So I cannot say
if this is a common or recurring thing, although I don't think my
surfing experience is what it should be on this T1. Now I have read about problems with lookupd having its cache messed
up, could that have the effect of returing the wrong IP for an
address request. Looking in my crash logs lookupd has gone south
three times in the last couple of weeks is that telling or not? I
have attached the most recent crash log in case it might help. Any suggestions or do I just have to firewall off my machine from the
rest of the company so Slashdot will turn us back on and I won't get
burned at the stake? Productivity is up but moral is hurting a bit... Thanks a bunch! -Eric Host Name: Omppu
