Unable to add parameter to /proc
 

I am trying to increase the ip_conntrack_max value in /proc.

I tried:
# echo 65536 > /proc/sys/net/ipv4/ip_conntrack_max
-bash: /proc/sys/net/ipv4/ip_conntrack_max: No such file or directory


# sysctl -w net.ipv4.ip_conntrack_max=65536
error: 'net.ipv4.ip_conntrack_max' is an unknown key

and finally I tried to manually add this key to sysctl.conf

none of them worked. I have another box with the same setup (same OS and Kernel version) and it has this value present in /proc (I did not setup/install these boxes).

OS:RHEL3
Kernel:2.4.21-15.0.2.ELsmp

anything else I overlooked?

Thank you.

Maybe the module isn't loaded?

that was it! thanks.
