Thanks for responding Anthony, 1) Same problem as before ' iptables: No chain/target/match by that name' 2) User defined chains work - and I can put a drop rule without problems. Kernel: A new box just bought - I thought the kernel was old - but I had to demo a product for a client - and wanted to get that done before I pester the VPS hosts to upgrade the kernel. I can see the libraries on the box for both logging and User Space Logging - seeing if their being used is harder to establish. I guess the kernel install didn't do a proper job of installing iptables.

It seems unlikely, but has your kernel been compiled without support for the LOG target (and by the way, why are you using a three year old kernel anyway?)? Test one thing at a time: 1. Can you use the LOG target? iptables -A INPUT -j LOG 2. Can you put a rule into a user-defined chain? iptables -N logdrop iptables -A logdrop -j DROP If both the above tests work, then there is no reason you shouldn't be able to put a LOG target into your user-defined chain (so check very carefully the syntac of what you are typing when you get the error, etc). If one of the above tests fails, you know where the problem is. Just one last thing to check - you haven't compiled the userspace iptables tool without also recompiling the kernelspace netfilter part, have you? If you do one of these, you should also do the other to match.
