I have a problem on Ubuntu 10.04.3 LTS x64 with sysctl
. If I run this command on shell, I get back an error:
error: net.ipv4.netfilter.ip_conntrack_max" is an unknown key.
It occurred on 2 of our machines after a reboot. The sysctl value
net.ipv4.netfilter.ip_conntrack_count and all other conntrack-entries are also affected.
This is really problematic because we have a very high load / traffic system and I have written a Nagios script which check this value, because we had several problems in the past with this value. On other machines I have set the
conntrack_max to 196608 to solve any problems but now I can't set the value on the affected machines. Is there set any default value at the moment?
Has anyone an idea to get back the two values on my systems?
