Hi all
Im a very confused about Conntrack and TCP performance. Was one of the little issues that I noticed when we start to use OpenVZ. I don't know really if was a problem of OpenVZ or problem of Linux itself, anyway, I could resolve with success, editing values of conntrack in sysctl.conf and then applying changes:
net.ipv4.netfilter.ip_conntrack_max = 65536
We have 5 servers running under OpenVZ and kernel version is 2.6.18-92.1.13.el5.028stab059.3PAE. But recently we tried another version and now, when I try to edit sysctl.conf and apply the changes, kernel returns
error: "net.ipv4.ip_conntrack_max" is an unknown key
I checked proc subsystem and I didn't find the "file"
[root@hn19 ~]# ls -ls /proc/sys/net/ipv4/ |grep conn
[root@hn19 ~]#
I'll like to understand more this issue, because I really don't know what is the main question here, why we have troubles in past in conntrack and if is a persistent problem on TCP linux performance.
I'll keep find a solution for this but if someone is so kind to explain a little the main problem will be very helpful to us.
Thanks.
