Firewall?

Post by pensioner77 »

When I was using Ubuntu as my OS I had Firestarter installed as a firewall, this does not appear to be available in Mint17, Is there an alternative?

ufw should be installed as default and you could use the GUI to configure it

Firestarter seems to have been removed from the official Ubuntu repositories in version Ubuntu 13.10 or maybe earlier. As a consequence, any Mint release, starting with Mint 16 will not offer Firestarter in the repositories, either.
Seems Firestarter has been removed, because it had no longer been actively maintained for several years.
No firestarter
Ubuntu on Firestarter
Ubuntu on Firewall

As PatH57 suggested, use the uncomplicated firewall ufw instead and if you like its GUI gufw.
Note:
Because this behaviour has led to misunderstandings in the past. Gufw will not even display the current state of ufw unless you have clicked the [Unblock] button.

also if you use a router chances are a firewall is already on it.

There are advantages to both a hardware firewall and a PC firewall. The hardware firewall is isolated from your computer, which you run potentially bad code on that could compromise the integrity of the firewall. The hardware firewall may still have problems with it, but it is likely far harder to compromise. The disadvantage however is that a hardware firewall knows very little if anything about what program is making an outgoing connection. It is best at keeping out intruders as opposed to keeping bad things from getting out to the Internet since that would take far more complex configuration of denying any connection that isn't explicitly configured as allowed.

A software firewall on the other hand runs on your computer and is aware of the application that is trying to access the network. You can allow things at a much more granular level and it will do more to prevent a bad program (or even a good program) from accessing the network in a way you don't want it to, but the down side is that a smart bad program may be able to disable the functionality of the firewall and get past it.

Thank you everyone, I have installed ufw from its web site. I was unable to find it on Software manager, in fact I can find nothing on there unless I laboriously scroll down all the programmes until I find what I am looking for. The search slot does not seem to react to anything, I have tried Left Clicking, right Clicking or double clicking, on the Magnifying glass icon, the entered name,all with no avail, only the Xarrow deletes, as you would expect! It is not because the programme is not there, I tried entering Firefox but with no result.

In my Mint 17 MATE, GUFW shows up as "Firewall Configuration" in the Menu under Preferences. I don't recall deliberately installing it.

Yes, the Software Manager is a little buggy. For this reason, I use Synaptic.

ufw will come pre-installed on any Ubuntu and Linux Mint installation. So there should have been no need to install it at all, because it should have been there already.

Hm, cannot imagine why. Found it immediately.
