All, I'm attempting to install ipset via the instructions at ipset.netfilter.org on a SuSE 10.0 box. I've gotten as far as the step where I run: KERNEL_DIR=/usr/src/linux make in the iptables directory. The first time I tried this I got an error about missing dependencies that suggested I try running "make clean," so I did. Now when I try running the instructed command, I get the following: linux:/usr/src/iptables # KERNEL_DIR=/usr/src/linux make Extensions found: IPv4:CLUSTERIP IPv4:recent IPv4:set IPv4:SET IPv6:ah
