Firewall?

a_hic · 06-02-2002, 06:49 AM

when I worked on windows I have Zonealarm as my personal firewall,
I work on ethernet network, is there a free firewall for Linux to prevent
against attacks, because on my network there is many mlicous man!

Linux comes with several firewall options, depending on your kernel version.

For 2.2 kernels you have ipchains - see "man ipchains"
For 2.4 you have ipchains or iptables (depending on how your kernel was configured) - see "man iptables"

not only firewall if free in linux

and presumably you want a nice easy GUI to make it go... try firestarter. it's pretty good.

Why does everyone want a gui for those things?
Whats wrong with just a linuxbox without al the gui-crap on it?
Is'nt that the best way to start learning linux?
My opinion is with a gui you aren't learning something of the os itself.

I have had great luck with gShield. Just edit the config file, add a few blacklisted hosts to a file, and you are good to go. It even does NAT!

The downside is that there is no GUI, but it's really so simple that you don't need one!

firestarter.sourceforge.net

google - firestarter

I've been using firestarter for a few weeks or so now. It's been doing a fine job IMO.

I will tell you why it's all about the GUI. See, most people who are learning linux (myself included) don't have a lot of spare time to remeber all the command lines of a gui. And linux has a lot of them. But thankx to GUI's, commands are needed, mouse clicks are.

true... but all you really need to know about iptables and what have you can be stored in a bash script file and just executed. i don't consider myself an iptables expert or anything, but i knew enough to setup my own firewall.

i just think that every linux user should be VERY comfortable in console. remember... linux is based on the console; X is just a luxary. :-)

I would rather drive the S class of Linux then the pinto!!

Because most people that are learning LINUX had Windows as there previous OS, and what windows is is a GUI with no commands what-so-ever(unless u prefer using cmd.exe)

I doubt that it would be a good idea for a newbie or any non networkexpert to install linux for the first time and set up a firewall with the command line.
With programs like firestarter and guarddog you have at least some guidance and the thing won't be completely screwed up.
Not that I think it matters much - there aren't that many hackers out there looking to crack Joe Sixpacks box.

Don't count on that, I average 4 attempts against my firewall a month. And that's a dial up connection! Granted it's connected about four to six hours a day, but still.

Just using simple extrapolation, that would up it to 16 attempts/month for a full time connection.

Just because I'm not paraniod, doesn't mean someone isn't out to get me

crashmeister · 06-08-2002, 11:43 PM

I got an adsl connection that is up for about 14 hrs daily. Haven't had anything happening so far - no firewall here.
