Changing the ip_ct_tcp_timeout_established value

Changing the ip_ct_tcp_timeout_established value

[Björn Eberth]

Hi there,

the default value for "ip_conntrack_tcp_timeout_established" is set to 5 days.
My problem is, that after about 2 days of using a filesharing client the ip_conntrack table runs full.
Im using a dial-up connection with 24 hours reconnect.
So my question is: Could i run into problems, if i set this value to 24 hours or something like this?

Regards
Bjoern

Hi there,

thx for the answer, but it seems as this doesnt fix my problem.
It seems as if the value in "ip_conntrack_tcp_timeout_established" isnt interpreted, cause i see lots of entries like this in the ip_conntrack table:
tcp      6 231752 ESTABLISHED src=yyy.yyy.yyy.yyy dst=xxx.xxx.xxx.xxx sport=3139 dport=6881 src=xxx.xxx.xxx.xxx dst=zzz.zzz.zzz.zzz sport=6881 dport=3139 [ASSURED] use=1

The third field is the timeout value i think? So this would be 231752 seconds, which is much larger then the value in ip_conntrack_tcp_timeout_established.
Im running a 2.4.27 kernel with iptables 1.2.11. Is the value ignored in this versions by design?
Any advices?

Regards
Bjoern
