what really goes on?

Hey Guys,

I was wondering if anyone could tell me what really goes on behind pmfirewall? ie any changes to /etc/*

Is it just a frontend for ipchains?

Thanx in advance

im pretty sure but not absolutely but i think ipchains just stores all the rules in ram so it doesnt have to read off the disk everytime a packet hits the computer

I like source it never *****es about dependencies

PMFirewall is just the same as any rc.firewall script - it just uses a CLI user-friendly auto-install script that helps you choose some options - All it is: IPCHAINS commands in a configuration file - then read by a script that puts them, yes, into RAM.

just don't compare PMFirewall to something like CheckPoint or any Firewall software app for Windows - it isn't that at all http://www.linuxnewbie.org/ubb/smile.gif it's just a bunch of IPCHAINS commands.

yes, fandelem is right. its just the good-old torture-tested bunch of IPCHAINS

ahhh ok thanx guys

so if you didn't have rc.firewall or pmfirewall on your linux box you would have to make your own script with a whole bunch of ipchains commands?

and if you did make your own script, would that load into RAM like pmfirewall?
