Viruses using exploits on ports are quiet rare, it's more likely that somebody would try to invade your computer that way. As long as your firewall blocks all ports except those you need (just take a random range) and use those for all tcp/udp programs you have (of course never use the same port twice). For example i have blocked all except 7000-7050 , should be completely safe as no programs except for file sharing tools are listening to those ports. No programs listening behind the ports results in no risk. Well what you can also do is always unblock the standard port for the programs you use, meaning unblock port 4662 4672 that you mentioned (ooh yeah to improve security make sure you only allow the protocol that's necessary, let's say if 4662 is your amule tcp port only allow tcp protocol and for 4672 only allow udp).
Believe me that's safe.
You may want to do some ports scans on your windows friend and you'll see ports with programs listening behind, yeah almost all windows users have those. Program listening on an open port : potential risk: only an exploit (buffer overflow or something similary) is needed to harm your computer. Windows user have for example 5000 : plug and play and 139, the netbios port open. Usually on your Linux box there shouldn't be any ports open, only if you use VNC, secure shell or ftp ,generally servers or remote administration programs(make sure you set proper passwords and if remote is only necessary within the local net make sure to set a rule that makes sure of this). So like I said, block all, unblock what you need.

edit: and what i always wanted to say, hey delta nice to read you again, has been a while ...that is if you were the person who did the emule mods in the past...

yes I have a high id but I was just worried in terms of safety for my computer as I understand that it exists many viruses on the net...

anyway I will keep it running this way with those parameters and se what ahppen...


thanks again for your prompt support!!

I will be a strong supporter to linux and amule!

cheers

there are no Linux virusses ever reported "in the wild". (yep, very unlike windoze ;-))
you might be subject to a hacker, (just like windoze) but its very unlikely they choose YOUR computer (and are able to break in, cuz this is more difficult in linux). and IF they broke in, they have to get your root-password somehow, cuz without it they can't do much. (the same goes for virusses, but as I said there aren't any, as for now).

and because of the enormous diversity under linux, when talking about for example desktops (icewm, kde, gnome, fwm, twm, xfce), email software (evolution, sylypheed, mozilla-mail, thunderbird, Kmail), browsers (konqueror, mozilla, firebird, galeon, nautilus, netscape, opera) etc, it is very unlikely a virus will ever spread very far (cuz almost all virussus only target one security hole in one program in one version, exept under windoze, cuz almost all windoze security holes exist for a long time in many versions cuz m$ isnt very fast to fix them)

hmmmm got long isnt it

sorry for my english but I guess you get the point - unless you run a server, or unless someone really wants to hack YOU, you don't really have to worry much for your security.

ow, and welcome to the LINUX crowd, and thanx for the support!!!

[fcr]

thanks again for all your comments. It helps me a lot to understand this new system that is linux for me: It is only the fourth day today that I am using it...

Regarding amule : is there a way to include a parameter so hat my computer will autoupdate if a new version is available? In otherwords what is the proper procedure to upgrade to a new release.



My next challenge is now to manage to connect my digital camera to my computer. I was previously using it under windows with some specific softwares provided with it...I bleive Linux i a long quest...

Cheers

here you have to learn a thing: in windoze you had to update every program independent of the others. Linux is much more advanced on this: all software is managed in a central place, you're package management. If you dont compile it yourself (I whouldnt do it, it will cost you alot more work) then an FULL update of your WHOLE system, including ALL software to the LATEST versions shouln't take more than TWO commands.
In debian, it is:
[code:1]apt-get update[/code:1]
[code:1]apt-get upgrade[/code:1]
in mandrake it is:
[code:1]urpmi.update -a[/code:1]
[code:1]urpmi --auto-select[/code:1]

dunno about the others, but it should be similar. Some distro's aren't this advanced (yet), but I guess a newbie like you did choose an convenient system... like mandrake, red-hat or an easy-debian version (from which, although I have Mandrake, whould recommend debian, because of its superior package management, although its hardwaredetection/configuration isnt that advanced, compared to for example mandrake)
