Kernel Firewall Support

Aeiri · 03-06-2004, 11:13 PM

I am trying to install isinglass as a firewall (http://www.tummy.com/Software/isinglass/), but I'm getting this error:

Quote:

isinglass: ERROR: Unable to locate 'ipfwadm' binary.
ERROR: Unable to locate 'ipfwadm' binary.

I think this is because I don't have firewall support in my kernel, so how would I go about enabling it?

Is it possible to do this in "make xconfig" or "make menuconfig", or do I have to recompile the kernel myself?

If I have to recompile the kernel, how long would that take?

ipfwadm was a kernel module used in earlier kernel versions 2.0.x, 2.2.x used ipchains and 2.4.x and up moved to netfiletr/iptables, you can get ipfwadm backward compatibility by reconfiguring your kernel (in netfilter configuration) and re-building the kernel afterwards.

Thanks, I've been reading up and it looks like iptables is the way to build firewalls, but I get:

aeiri@localhost:~$ iptables
-bash: iptables: command not found

Linux tends to do that to you =P
