Subject: xt_hashlimit: max count of 8192 reached
Date: Sun, 18 Nov 2012 17:45:42 +0100 [thread overview]
Message-ID: <50A910B6.4000607@evcz.tk> (raw)
I'm using this ruleon iptables v1.4.7
iptables -A INSYNSRCLIMITER -m hashlimit --hashlimit-htable-expire 10000
--hashlimit-htable-size 8192 --hashlimit-htable-max 8192
--hashlimit-mode srcip --hashlimit-name insynlimiter --hashlimit 1/s
--hashlimit-burst 25 -j RETURN
while being "synflooded" and I'm seeing a lot of
xt_hashlimit: max count of 8192 reached
errors logged... really a lot (just to explain how many of those: got a
bunch of "net_ratelimit: 42695 callbacks suppressed"logged too...)
What does exactly that errors mean?
did there was more then 8192 srcip to track and hashlimit went in
overflow or am I using --hashlimit-htable-size and
--hashlimit-htable-max in the wrong way?
