Re: Clearing State Table

Below is the output on 4.1.28. In this case my statemax is 7000 and you
are right, it was at the default before and it's dumping the active
states when it hits the defined maximum. What is TCP State 10? Is that
TIME_WAIT? My tests in 4.1.28 now eventually have the states clearing
but only after 4 minutes. Maybe before I wasn't patient enough and it's
possible the only trials where I let it go for a long time where with
older versions. If it is just in TIME_WAIT, then is that time setable?
The host is set to only keep it in TIME_WAIT for 60 seconds. Even so,
is there a way to make the (limit X) option in ipf.conf only count
against connections in the ESTABLISHED state or just not include
TIME_WAIT? Otherwise, it's still not really counting X concurrent
connections as much as X connections per TIME_WAIT period? In my case,
we would be getting a lot of connections in quick succession, but I want
to limit the number of connections being made at simultaneously. That
make sense? Thanks for your help.
