CLUSTERIP error "iptables: Invalid argument"

CLUSTERIP error "iptables: Invalid argument"

[alex_oz]

Hi,

I tried the new Netfilter target CLUSTERIP using kernel-2.6.10. I discovered
that there is still no userspace support in iptables-1.3.0. So I added
"CLUSTERIP" in iptables-1.3.0/extenstions/Makefile and rebuilt
iptables-1.3.0 with CLUSTERIP-support.
Nevertheless it seems that shared library and kernel-object doesn't fit
thogehter. When I try to input a CLUSTERIP rule like:

iptables -A INPUT -j CLUSTERIP --new --hashmode sourceip --clustermac
01:ab:cd:ef:ab:cd --total-nodes 2 --local-node 1

there is the following error:

iptables: Invalid argument

Did I use wrong parameters?

Really? It seems to compile just fine here

you forgot to add the interface and the IP, eg: -i eth0 -d 1.1.1.1

CLUSTERIP is still marked as experimental, so maybe you could find any bugs.
