Bug 24915 – guarddog fails with iptables and 2.6 Linux kernel

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Roger Luethi 2003-07-20 13:44:00 UTC]

guarddog uses some shell scripting to determine whether to
use ipchains or iptables. The relevant code in /etc/rc.firewall
looks like this:

if [ -e /proc/sys/kernel/osrelease ]; then
  KERNEL_VERSION=`sed "s/^\([0-9][0-9]*\.[0-9][0-9]*\).*\$/\1/" < /proc/sys/kern
el/osrelease`
  if [ $KERNEL_VERSION == "2.5" ]; then
    KERNEL_VERSION="2.4"
  fi;
  if [ $KERNEL_VERSION == "2.4" ]; then
    if [ -e /sbin/iptables ]; then
      FILTERSYS=2
    fi;
    if [ -e /usr/sbin/iptables ]; then
      FILTERSYS=2
    fi;
    if [ -e /usr/local/sbin/iptables ]; then
      FILTERSYS=2
    fi;
  fi;
fi;

Obviously, this doesn't work for the recent 2.6.0-test1 kernel.

Reproducible: Always
Steps to Reproduce:
1. start guarddog
2. set some rules
3. hit "Apply" button

Actual Results:  
ERROR Can't determine the firewall command! (Is ipchains or iptables installed?)

Hopefully you actually use this, as you commited last few versions Martin.

It's getting fixed upstream.

[Comment 3 Roger Luethi 2003-08-11 01:13:39 UTC]

2.1.7 was just released and has it fixed (according to the announcement).
