Hello,
I need help to diagnose where the problem is...
Below you can see traceroute and ping to facebook.com but the same
happens with other domains.
I restarted router, logs show no errors.
OpenBSD 4.8
#traceroute facebook.com
traceroute: Warning: facebook.com has multiple addresses; using
69.63.189.16
traceroute to facebook.com (69.63.189.16), 64 hops max, 40 byte packets

I see that for more than 24h inserts and removals in state table are
higher than normal:
State Table Total Rate
current entries 8876
searches 53632700 2157.6/s
inserts 4318144 173.7/s
removals 4309268 173.4/s
Counters
match 4673697 188.0/s
There is many connections like this:
all tcp AAA.AA.AAA.AAA:62146 (BBB.BBB.BB.B:59475) -> CCC.CC.CC.CCC:6667
TIME_WAIT:TIME_WAIT
all tcp CCC.CC.CC.CCC:6667 <- BBB.BBB.BB.B:59476 TIME_WAIT:TIME_WAIT
CCC.CC.CC.CCC:6667 is some SVN server...
My questions are:
1. Does so many connections to some uknown svn server looks suspicious?
or is it normal behaviour when connected to svn server?
2. could so many inserts/removals cause problems with ping and
traceroute? and dns (problems/slow resolving) ?
3. what can be done to tune router and get higher inserts/removals rate?
best regards,
RLW
