Firewall configuration ?
I've just setup Suse 9 and would like to run a webserver. Im new to linux and need a bit of help. My questons are:
How do I allow connections on port 80 for http access, connections on port 21 for ftp access and on 22 for ssh access?
My webserver is up an running, I can access my default page by typing 127.0.0.1 into my broswer url bar and it works. I also have a domain name setup. I would like to access the servers above by using the domain name of my linux machiene. Eg I would like to enter the url "suse.local" into my browser on my mac and get it to display the default web page.
There are tons of great firewall options available. There are tons of great iptables tutorials online like http://iptables-tutorial.frozentux.net/, http://www.netfilter.org/documentation/ (official docs) and http://www-106.ibm.com/developerwork...linuxfw-i.html
(requires free registration)If you want to go a simpler route, maybe check out shorewall, its a front end to iptables. Also there are tons of great scripts out there, http://easyfwgen.morizot.net/gen/index.php is a great site for generating firewall scripts. I hope this helps!
