Firewall settings don't stick
« on: 22 August 2003, 05:19 »
I've noticed that when using Redhat's "Security Level Configuration" tool to set firewall rules (redhat-config-securitylevel) in Redhat 8 it won't allow me to change them (No, it doesn't matter if I'm root, i'm sure someone is going to wonder about that   ;)  ). It acts as though they have been changed but displays the same default settings the next time I use the program. There is a hardware firewall between this computer and the internet anyway, so it isn't even really necessary... anybody know of a way to forcefully change / disable this?

what do u want it to be at?
what does the following command give you:

ls -l /etc/sysconfig

what are the contents of /etc/sysconfig/iptables
(or ipchains, not sure which it is...)

haha yes, I've been trying to (I actually have the ISO's but am having trouble burning them right now). I figured I was just doing something stupid, but... you think I won't have this problem in 9?

xcdroast is great, u try it?

and you dont have to go to redhat 9 to have things working... you'll have to excuse raptor he's been an avid windows user for quite some time. you posted a minute after i did so i dont think u saw my previous post.

First of all, yes, that's exactly what I did (I was typing my post as you posted yours). Also, yeah, I've been using xcdroast for burning every ISO I download, only had trouble recently... I don't know, there might have been something wrong with the CD's... or maybe it was the settings... whatever.

I want it to be at... medium I guess is fine... specifically I want to have some ports (25, 22 and 110) open...

Anyway, here's that information.

umm... ok, I noticed what it said about "lokkit" in that second part, so I found lokkit, ran it, and changed some stuff... now this is what it says (although the actual settings don't seem any different)

(Edit: first, I should have disabled smilies before... it garbled some of the info. It should be fixed now. Also, forgot to say, thanks for responding.)

  :D  Thanks, I think so too. Not many people recognize it (except for here, for some reason) let alone the other one I use sometimes, Svlad Cjelli (although it's happened).

What do you use, out of curiosity?
