how to compile kernel to support ipchains?

scientist · 03-29-2005, 11:22 PM

hi all! I am using linux slackware. I am going to use IP firewalling with ipchains; So when I try to play with this utility, it seems my kernell does not support it. It says something like 'kernel incompatible with this protocol', when I try ipchains -L command, etc ...

I know I might have to rebuild my kernel to support ip filtering, does anybody could please give me a course on this ...

Thanks!

u just need to open up the current config file of ur present linux distro in the kernel source and then in the networking support u can get ipchains sypprt
enable that and compile ur kernel

a good kenrel compile guide is here

is there a particular reason why you want to use ipchains instead of iptables???

just curious...

masand - thanx alot (%

win32sux - I dont know why it's ipchains, if iptables are also ok, I will take it ...

... also I have noticed that iptables work on my system, I guess I'll choose them instead ...
could you give me a simple tutorial url how to configure iptables to have a fine firewall against external world ...?

ipchains is what was used back in the linux 2.2 days...

since linux 2.4 iptables has been the norm...

this is the official iptables (netfilter) website:

just my two cents...

you're very welcome... BTW, there's also a small iptables wiki right here on LQ:
