Redhat security level help

[JUMBOshrimp]

Hi all -- I'm pretty new to Linux and im having some problems.

Im trying to configure my system (Red Hat v8.0) with NO firewall. I have tried to use the redhat-config-securitylevel but it reverts to its original settings everytime i close it. I have tried the lokkit program as well with the same results. I have also Tried to configure the iptables manually to no avail (Im not sure how to do it in the first place)

Specificly I am trying to set it up so I can use gaim, kit or AIM. it sends out the password and the problem comes from the responce not being able to reach me.

misc info-- My ip on the Redhat box is 192.168.0.3 -- The gateway to the internet ip is 192.168.0.2 If you need anymore info I will be glad to provide. I have looked all over the internet and it seems people are having the same problem but when they figure how to fix it they dont post it.

Thanks

Fine -- If nobody knows how to do that can you at least tell me how to setup iptables to accept everything (specificly All incoming) from eth0 (192.168.0.2).

like I said all the Transmissions go out fine but when they try to make it back they hit the firewall (everything but port 80).

Thanks

Follow my sig on quirks. The redhat security GUI is NOT showing what it is set at, it always shows high, regardless of what it currently is.

I set it to 'none' and use firestarter.

it is not the case.
when you start the firewall setup
it is assuming that you wish to create a new firewall.
it is design to create your rules, not display the current settings.
there for it displays the defualt settings.
those rules are not set till it is confirmed "ok".
then next time you start the firewall tool again the settings show the default of high.

where this tool really lacks is in the creating of more complex rules.

I myself use guarddog. but knowing how the firewall setup tool works is wise.
the redhat firewall setup tool is nothing more than a ncurses version of lokit.

I can understand your problems figuring this out. Firewalls were tough for me at first too. Along with the constant changes to latest versions of both RedHat and Mandrake. I know use Mandrake as I have less problems with that version.

To get back to your problem. IF you don't login as root from console and start a X-Windows session, then the easiest way to access and control the system is WebMin. WebMin site (http://www.webmin.com/index.html)
Accessing and control your system from this setup saves you a few hassles and is very efficient for me in some ways.

I also recommend Shorewall for a firewall. You can easily turn it off or on even with WebMin and it is very easy to configure within WebMin with far less knowledge then some of the others...

With shorewall... Configure your main zone and just set it to ACCEPT ALL for that Node.
