Anyone using IPSET and/or has successfully installed and compiled it with Debian Lenny amd64?
I'm keen to get IPSET running on a few boxes to cater for some custom iptables rules which at the moment are being initiated with bash scripts and it's very slow. I understand IPSET is specifically made for speeding up this type of function with iptables.
I've tried the following:
apt-get install ipset
apt-get install module-assistant
apt-get install netfilter-extensions-source
module-assistant build netfilter-extensions-source
module-assistant install netfilter-extensions-source
But get an error "Bad luck, the kernel headers for the target kernel version could not be found....etc" and a headers files message.
I've never really got into the kernel side of things so this is going over my head.
Any suggestions or help would be appreciated.
