How about what you've already developed for Linux?

Yes, I know it’s probably not possible but it would be an interesting addition to your product line. CPF, CAV etc for Linux. Think of the possibilites!

checkout :slight_smile:

We already have a linux based firewall :slight_smile: and other infrastructure solutions like ZTL :slight_smile:


Trustix looks good but I was hoping for something I could install on an existing Linux, like Arch or even LFS.

u seen ZTL?


I’ve seen the web page. It’s a remote server management system, isn’t it?

nooooo :slight_smile:

check this out
“ability to install and configure Web, Mail, DNS,
Domain Controler, File Server, Printer Server as well as Database, DHCP, Proxy servers, Firewall servers”

Its everything you need to run your business! its your back office under one application!
its very powerful!


Well I’m sure it’s a fine product but that’s not what I’m looking for either.

Let me be more clear. Right now I’m using Arch Linux and I don’t have antivirus or a firewall. It would be nice if I could use something like CPF and CAV on my Linux installation.

I don’t need an entirprise solution because it’s my home computer, not a computer at work, and it is not a server, it’s my desktop machine. And it would be even better if it was free.


try and download the Trustix Enterprise firewall. You will need a seperate machine for it though. (so it might not fit your requirement.)…

Exactly my point.

Is it possible to build a consumer free firewall for Linux that regular consumers can use on their workstations?

debian / fedora core comes w/ a firewall and I think grisoft makes a free linux AV
you could go that route DLBarron there may be others… did you check source forge or linux dot net or org you could also check the debian web site as well as gnu and or kde sites
all ya gotta do is a (linux) google and I’m sure you’ll find something for free ASAP…
hope this helps

As I am sure that there are free products for linux provided by other companies I was just saying that it would be great if Comodo could make one for Linux.

I agree, one thing I don’t like is when you have to choose programs that you don’t really want simply because of what OS, Browser, etc… you decided to purchase/use. It will always be that way and I accept it, I just don’t like it. But either way, I am running XP so I can use it…Hooray for me… ::slight_smile:

As am I but I am dual booting Kubuntu Linux for Malware Research reasons, and will most likely completely switch to Linux in the next few years. My computer can handle Windows Vista but I am just not sure if I want to buy another version of Windows, XP works fine for me and I haven’t found a huge reason to upgrade from XP to Vista, Microsoft says that Vista will be more secure and the safest version of Windows yet, but they also said that with XP, and I am sure Vista will be the safest version yet, but everything from Microsoft has always been unsecure and I expect Vista will be also. If the only reason I should upgrade is because of security then I won’t. With programs like Comodo Antivirus Spyware, and Comodo Personal Firewall, I should be safe as long as Comodo supports Windows XP. But all that is just my opinion.


I am not going to buy another version of Windows until there is enough support for the 64-bit side of it. I installed the trial of XP Pro x64 and wasn’t impressed at all, in fact that first time i did it I couldn;t even get online because of the poor driver support. Also, If anything is slowed my typical 32 bit apps down.

Switching to Linux has crossed my mind and becomes more appealing as the support grows. I read up on Kubuntu after Melih posted about you liking it so miuch. I may install it or another version on the PC I use for testing.

Comodo definitely makes XP that much more attractive, but it would be nice to be able to run it either way.


I completely agree with you. And I really like Kubuntu and will stick with it, the only problem I am having is installing the Nepenthes honeypot but I am working on that everyday and eventualy I may get it right. Plus what fun is a new OS if you know everything about it? ;D

Yes, I’ve looked all over the universe for firewalls and antivirus for Linux. So far the only thing I’ve found is a firewall called iptables (which is a hassle to setup) and ClamAV. I’ve never heard any information positive or negative about Clam

Hmmm…You folks seem very inexperienced in the Linux part of the world.

(1) We don’t use personal firewalls like those in Windows. We use what is already built into the kernel. That is, iptables/iproute/etc. (You use netfilter to interface with those tools). In Linux, firewalling is built-in from the start. There’s no need for third-party firewall application to install.

(2) There’s two main ways to use iptables. You can actually learn the command line approach OR use an application that will automatically do things for you. (A pretty GUI that simplifies things when configuring iptables).

(3) One example of such an application is FireStarter. See
(If you use Ubuntu or some other variant, FireStarter is actually in the repositories. Do any of you use the Package Manager?)

(4) ALL Linux distros use the same firewall, because they all use the same kernel! :slight_smile:
(It is the exact same solution used in Linux-based routers like Linksys WRT54G/GS/GL/etc series).

(5) In regards to most malware and such, the Linux people don’t usually bother with solutions like anti-trojan, and such. What we have instead is security frameworks and solutions that prevent or limit the damage or contain those kinds of attacks. Please see SELinux, Novell’s Apparmor, PaX, grsecurity, etc.

(6) ClamAV is the only open-source AV solution. This was originally designed to filter/scan e-mails. Its not really for desktop users. (Although there is a third-party GUI for it)…When I say “open-source”, I mean you can download its source code, understand how it works, modify it for your needs, etc, etc. Solutions like AVG Free for Linux are “closed-source”…You aren’t able to see the details, you can’t modify it, and if there’s a major bug, you have to wait for Grisoft to fix.

(7) If you take a closer look how fast the open-source community releases new patches and versions of software, you’d wonder why a multi-billion dollar company like Microsoft can’t do the same! Typically, open-source brings out fixes within hours to a week at the most. Microsoft goes for the monthly “train schedule” approach. By then, many people have been infected with something that could’ve been prevented, if MS had released a fix faster.

As you can see, when you switch to Linux, you must drop most of the nonsense you picked up in the Windows world. We do things very differently. And most often, people try to treat Linux like Windows, which ALWAYS is a guaranteed failure to accept Linux. (I’ve seen it in blogs, forums around the world, and in real life)…The fact is, to really appreciate and use Linux to its full potential, the user must put some effort in to understand it.

Think about it. Windows Vista is gonna have a new pretty interface…People take the time to learn that. But when it comes to Linux, everyone will think of some poor excuse not to adopt it (any and every excuse, because they are afraid). The only thing that should be really stopping you is application support. If you can’t run it in a Windows-application layer (WINE) in Linux, or you can’t run it under a virtual machine, then don’t bother with Linux.

The way I do things is have Linux installed, then VMware Server 1.0 (free virtualization software), and run Windows, BSD, other Linux distro, OS/2, etc in a virtual machine. This way, Windows can die a spectacular death, throw hissy fits, etc…And I can simply roll back the good “snapshot” I made for it in minutes. (to restore the last good condition I saved)…The only major issue is, you can’t play 3D games with it. (Its HARD to virtualise this, but its been worked on). But its a great way to learn other operating systems without spending a dime.

Have a think about “Windows Genuine Advantage”. If you think its a bit harsh/annoying now, just wait and see what Microsoft has in store for the future!

Learning and trying Linux is about giving yourself the choice when there is none. That’s the key idea of open-source…The freedom to choose what YOU want to do on the computer that YOU paid for.

Companies like Comodo, who embrace open-source (see their Trustix distro), understand the potential market. The issue for them, is trying to strike the right balance in making money while not angering the open-source community. (When you ■■■■ them off, no one would use your product…Even worse, they will write their own equivalent solution!).

Compare this with Microsoft’s approach. Since 2001, they have called Linux and its license a “cancer” (CEO, Steve Ballmer said that) and referred to it as “Communism” (Bill Gates)…Heck, their best anti-Linux example is their “Get the Facts” site, that’s still up! (biased studies that always favour the Microsoft solution as the winner)…And now, they’re opening/starting up things that are similar to open-source, their version is called “Shared Source”…But no one in their right mind is taking the bait. The open-source folks have a VERY long memory, and we know what MS done in the past. If companies behave as devious as Microsoft, don’t expect any support from the worldwide open-community.

What Comodo is doing, by earning trust, is an interesting idea. If they can maintain honesty and gain credibility, it’ll earn them some good “brownie points” in the future. Being upfront about issues is all everyone is asking for, from any company. Honesty => Trust => More people will use your products.
