Ask Slashdot: User-Friendly Firewall For a Brand-New Linux User? 187

An anonymous reader writes "I am a new Linux user; I'm on 2nd day now. Currently I am trying out Ubuntu, but that could change. I am looking for a user friendly firewall that I can set up that lets me do these things:1) set up a default deny rule 2) carve out exceptions for these programs: browser, email client, chat client, yum and/or apt. 3) carve out exceptions to the exceptions in requirement 2 — i.e. I want to be able to then block off IPs and IP ranges known to be used by malware, marketers, etc., and all protocols which aren't needed for requirement 2. It also needs to have good enough documentation that a beginner like me can figure it out. Previously, I had done all of the above in AVG Firewall on Windows, and it was very easy to do. So far, I have tried these things:1) IPTABLES — it looked really easy to screw it up and then not notice that it's screwed up and/or not be able to fix it even if I did notice, so I tried other things at that point... 2) searched the internet and found various free firewalls such as Firestarter, GUFW, etc., which I weren't able to make meet my requirements. Can someone either point me to a firewall that meets my needs or else give me some hints on how to make firestarter or GUFW do what I need?"

    I would suggest installing WINE and then running Windows Firewall.

    Shorewall is very nice. For the user I would suggest using it and installing webmin to configure it. Webmin does an OK job configuring shorewall which is already pretty easy to set up, just it can be fairly confusing for the first timer with all the config files. After the first few times with webmin you learn how to do it with the command line and vim.

    So let me sort this out, in order to easily configure iptables, shorewall is a good solution, but to configure shorewall, I will want to use webmin. So what do I need to install to configure webmin?

    No wonder why the year of the linux desktop will never be.

    Nothing wrong here: the Windows firewall is designed for keeping malware inside the PC and out of the Internet, the other firewalls are designed for keeping malware on the Internet out of the computer.

    This expert trusts Windows 8 for my family's security. All the UAC prompts frustrate the would-be penetrators so they move on to other targets. And since there's no way to find the shutdown button, it provides my loved ones with rock solid, around-the-clock protection from evildoers.

    Microsoft. Because your family's well-being shouldn't be entrusted to dirty hippies.
