I had installed RH 7.1, and found the GUI interface of firewall-config very handy (still getting the hang of term window commands).
For an unrelated reason I had to re-install, and have since lost that command. I therefore need to figure out if a) I even HAVE a firewall running (I can ping my address from another comp.), and b) how to configure it.
I do know that when I installed this time I set the firewall to 'high' security...
I don't know if you can, but I can. Just su to root and type setup you get the "text mode setup utility 1.7" with a menu kinda like this
Choose a tool
Run Tool Quit
if you choose the Firewall Configuration you get _________________| Firewall Configuration|_____
A firewall protects against unauthorized network intrusions. High security blocks all incoming accesses. Medium blocks access to system services (such as telnet or printing), but allows other connections. No firewall allows all connections and is not recommended.
That could be, I installed everything with RH 7.1 because I wanted to look at all of it and see how it all worked together and look for buggy apps. I've been pretty happy, not much core dumping, but I'm still having great fun with IPtables doing masquerading and forwarding. Take it easy.
I went to the sygate site, and most things were blocked, a couple were closed but ICMP was wide open. I looked through my firewall script (ipchains) to see if I could find where that might be set, but wasn't able to.
Preferably I'd like to run silent, do you have any suggestions?
