Bittorrent Problems!

I have just settled in to my dorm room at the University of Idaho, and plugged into the campus network via ethernet. I have been amazed at the general speed, especially with downloads, but greatly disappointed at the performance of torrent downloads using tomato torrent.

I've used this client before with great success on much slower connections, so am a little puzzled. What are some possible causes?

Has anyone experienced this before?

You may want to change your TCP/UDP ports for BitTorrent traffic. Most likely your school intentionally block or slow down certain ports associated with BT.

Your school doesn't want to waste bandwidth with BT so they limit the bandwidth that BT can use.

It is very expensive for a university to maintain an extremely high speed internet connection and BitTorrent can destroy their bandwidth, as in, suck it all up. They're just trying to not have to pay for an even faster connection which will end up soaked with BT stuff...

Just be glad they don't block BT altogether.

How do you do this?
You usually get a NAT error because of the network firewalling the general ports that are usually allowed. If you airport express that sucker, it's easy to set the ports open. But w/o it, I'm not cool enough to do it, although it's only supposed to be marginally difficult.

And yes, Tomato Torrent has too many failed hash checks. It's cute but doesn't execute Java well. The best choice for Mac is the RAM hogging Azureus.

You will normally find that collages do not want people torrenting so they block the ports via a firewall not allowing you to download torrents.....

This will not affect normal download speeds hence why you are having trouble downloading...

Maybe you could try and make the torrent application (use azereus) use a port that hasnt been blocked...

Had the same problem when I started uni last year. The *nix geek just did something called tunneling which meant i could bypass the firewall. Don't ask how, just find your *nix geek and get him to help :p
