This is the weirdest bit. I set it to high...but it doesn't do anything.
/sbin/ipchains -L says:
Chain input (policy ACCEPT):
target prot opt source destination ports
ACCEPT tcp -y---- anywhere anywhere any -> pop3
ACCEPT tcp -y---- anywhere anywhere any -> smtp
ACCEPT tcp -y---- anywhere anywhere any -> http
ACCEPT tcp -y---- anywhere anywhere any -> ftp
ACCEPT tcp -y---- anywhere anywhere any -> ssh
ACCEPT tcp -y---- anywhere anywhere any -> telnet
ACCEPT all ------ anywhere anywhere n/a
ACCEPT udp ------ intns2.ucc.ie anywhere domain -> any
ACCEPT udp ------ intns1.ucc.ie anywhere domain -> any
REJECT tcp -y---- anywhere anywhere any -> any
REJECT udp ------ anywhere anywhere any -> any
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):
In other words, accept anything from anywhere. In effect, there is no
firewall that I can see. I'll rename /etc/rc.d/rc5.d/S80ipchains and
reboot so that it's disabled completely. It's unnecessary anyway, I'm
not routing for anyone, this is an end-user desktop.
/sbin/iptables -L (I hope you didn't mean this) says:
init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
iptables v1.2.4: can't initialize iptables table `filter': iptables who?
(do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
