LutelWall (formerly known as Lutel Firewall) is high-level firewall configuration tool. It uses a human-readable and easy-to-understand configuration to set up Netfilter in a secure way. It can be used to build a range of firewalls, from very simple, single-homed ones, to complex ones with multiple subnets, DMZs, and traffic redirections. It can be used on a dedicated firewall system, a multi-function gateway/router/server, or a standalone system.
I wonder why patches like openwall or grsecurity are not integrated into standard kernel. Don't bother with back compatibility! I'm using 2.4.16 + grsecurity patch on production server (Apache, Postfix, Cucipop, PostgreSQL, Squid) and I must admit it is very stable and more secure than 2.4.16 kernel itself. Kernel deveopers, please - put those patches into kernel and good times for Linux will begin.
Wow! Good work ! :-)
This patch is amazing in terms of security. I'm using it by default in all my systems, and it's going perfectly well. THANKS!
