I have a question regarding security holes for bit torrent. Recently, I've changed the type of client I have, to a one called "Bit Tornado."

You can find where to download it at http://www.123torrents.com/blacklisted.php if you scroll down a bit. The site 123torrents asks its users to use a port range from 49152 to 65535. These port ranges apparently haven't been throttled by all high speed ISPs yet, and this has greatly increased my download speed. However, they briefly mention the possibility of security holes, and I was wondering about the implications of this.

There is nothing like what I have become.

Ah, but the smart ISPs like the one I work for that use l7-filter or something similar don't give a damn about port numbers [Razz]

Ditto [Smile] . You try and get SMTP traffic out of my protected network - fuggedaboutit.

There is no difference in security risk imposed by which port you use to connect to a service. It's dependent on the CLIENT ITSELF. If there's a buggy FTP program, changing it from port 21 to port 3350 makes it no more safe. It does introduce a certain level of obscurity, because the service is no longer on the port specified for FTP, bug the bug still exists.

Likewise, if a program is secure, but is moved up to a port in the 40000 port range, it isn't going to make it any less secure based on that alone.

That's interesting about the filter program you mentioned Spiderman. It's good to know that the port range doesn't make my computer less secure. I didn't know that it depended on the program itself, which makes sense though.
