Firewall?

what the best firewall available to ubuntu ?and still is there any possibility that RAT can get infected via WINE ?

A better question is ,

What do you want your firewall to do.

By default there are no significant open ports, so there is nothing to firewall.

Also, Firestarter conflicts with ufw, so use one tool or the other. If you want to stay with ufw, purge firestarter.

sudo apt-get purge firestarter

sudo apt-get purge firestarter

so if i get infected with a RAT u mean there are no way to get a effect ? and after reading some articles i guess ufw will be enough

What is a RAT ?
How would you be infected by a RAT ?
What makes you think a firewall will help with a RAT ? There are no open ports by default, so you are no more secure with a firewall.

Now if you install a server, such as VNC or ssh, and forward a port that is different.

remote administration tool, and that the question im having with "Wne" is there any possibility to get infected by a RAT ?

You already have a remote administration tool installed by default. Make sure it is turned off by going to System->Preferences->Startup Applications, and uncheck Remote Desktop. On the next reboot, it will be disabled.

There are reports of viruses running in wine. So long as you do not run wine as root they can not infect your system files, but they can infect files in .wine.

I would be less concerned that you are infected by "something" in RAT and more concerned in securing RAT. In that case, a firewall is part of security, but you need so secure RAT.

Well, there are remote access tools and there are remote access trojans (and in a lot of cases the only difference between the two is in who's running things on the client side). In the trojan context, it's another way of saying backdoor, except you get to turn it into an acronym which sounds more menacing in news articles and sales meetings.

A firewall won't really help you with those, though, since they initiate connections from the inside (end user's PC) to the malicious external device. Don't worry too much about those, since in Linux they aren't really a desktop issue. There's both more value and greater likelihood of success in getting them on a (poorly configured) web server. If you get one because of activity during a Wine session, it should only work while that's running (if at all). With a regular Linux desktop session you won't have sufficient permissions in anything for that to install itself automatically. You'd have to be tricked into installing it yourself, and you'd be asked for your password before it happened.
