Hi, my ip_conntrack table is filling up and now my server is dropping packets. I'm running CentOS release 4.4 (Final) on a fairly busy webserver. The table is full of various connections, including a lot of "ESTABLISHED" tcp connections from my webserver (the src is my webserver ip), and some other rand...

Hello I''ve got a server with 3Gb of ram and I want to keep 256 for the system and allocate the rest to conntrack ... I''ve tried to change the HASHSIZE of the ip_conntrack but dmesg return me this error ! ip_conntrack version 2.4 (2097152 buckets, 16777216 max) - 236 bytes per conntrack ip_conntrack: falling back to vmalloc. .... I''ve use this "math" to calculate it : (3072 - 256) x 1024^2 - 236 = 12511822,1027 The near "power of 2...

...bunch of servers, where I''ve deployed shorewall-lite. For us is very useful to have a centralized repository of the firewall rules deployed in our servers. One of this servers is pretty busy, handling lots of connections. In that server I''m getting from time to time this message: ip_conntrack: table full If I where working in a custom made iptables firewall I will handle that connections through the raw table, but on shorewall-lite I''m lost. I want to disable totally the connection tracking (not needed in this firewall) or handle some rules in a way that don''t use co...

...onnection slowing down and then stopping working. Rebooting the router box always fixes it for a while. When I couldn''t hit any pages this morning, and couldn''t even ssh into the router, I dug around a little. When I did a dmesg on the router, there were a bunch of errors saying: ip_conntrack: table full, dropping packet I did a quick search and found a mailing list entry somewhere that said that the table was filling (duh) and that you need to increase the max value. I checked the max value and it is set to 6192 on my machine. So: 1. Any idea how in the world I''m suddenly f...

...ely.. It has happened using CentOS 5.0, 5.1 and now also with 5.2. I'm not sure if it was the same bug earlier, but at least the last two times (with CentOS 5.2) it has been the same, see screenshots. Last lines of the console output: EIP: [<f8af2c5c>] __ip_ct_refresh_acct+0xa1/0x129 [ip_conntrack] SS:ESP 0068:c0724e4c <0>Kernel panic - not syncing: Fatal exception in interrupt At the moment firewall is running CentOS 5.2, Linux kernel 2.6.18-92.1.10.el5.centos.plus.

I'm not sure I understand. ip_conntrack shouldn't be unloadable while these modules are still loaded, so how can the oops happen inside them? Please check whether there are s...

I have just completed the installation of a new firewall running Shorewall 1.4 on Mandrake 9.2 for our campus network. It appears to be running fairly well so far, but is generating significantly more log entries than our previous linux 2.0.x firewall... Our previous firewall enjoyed more than 6 years of 24/7 operation with no downtime before we finally decided it needed more horsepower, and
