I've been running Ubuntu 12.04 as a non-geek, new Linux user for a couple of months now, a happy refugee from Windows, gradually finding out more, but mostly content to let the car run without looking into the engine.
I see from a Forum search here that there is an inbuilt firewall called iptables, and as I understand it from replies to a similar query there earlier, I probably don't need anything more to go with it, and that Firestarter is just a front end to configure it. I probably wouldn't understand what to do to configure it anyway
I did initially think "I need one of those" so installed Firestarter, but it claims it's not functioning anyway - the system log does not exist, it tells me.
I tried typing "iptables" into the dash search bar, and nothing comes up. Does this mean for some reason I haven't got the firewall & need to install something?
And if it is there, how do I get to see if it's working or not? Or is it just another bit of the engine I don't need to poke as long as it actually is there?
Would I do better to lose Firestarter?
Sorry, that's lots of questions, but they're all part of the same issue.
