rc.firewall?
 

I'm currently using Guarddog as a gui for iptables. When you first configure GD it looks for iptables in /sbin and spits out a bunch of errors since iptables is in /usr/sbin. After copying iptables to /sbin it configures. Next I noticed rc.firewall is not run on startup because rc.inet2 looks for it in /etc/rc.d/rc.firewall while GD actually creates it in /etc. I'm thoroughly confused. Did I miss something when I compiled it?

Probably you missed something (configuration options, probably). But the problem isn't big, you can make a symlink (/etc/rc.d/rc.firewall) to the file in /etc. It should work.

I edited rc.inet2 but two critical errors in a program? Maybe Slack's got me spoiled. Slack 9.0 is so solid you almost want to break something just for the fun.

No, it's a problem with the program. It uses wrong defaults. I can understand that it searches for iptables in /sbin, but /etc is not a standard location for rc.firewall (in most distros it's in /etc/rc.d/).
