Okay I'm a newb as of tuesday, and am teaching myself, not without the help of you wonderful people though. This isn't strictly a linux question although it could turn out to be. I am trying to get azureus working properly in linux and am experiencing some problems which I think may be firewall related. The problem is that I cannot get full connectivity, i.e. full p2p, or green smileys if you prefer, and am left with slow connections. My hardware firewall is properly configured, I know this due to azureus working fine in winxp. So this is definitely a software issue. Sorry for being so shit at this linux thing but you gotta start somewhere. Using FC3 (although probably not a good idea for a first linux system as i am finding out).

Fedora is a pretty good linux distro, is core 3 stable yet? Maybe core 2 would've been a better call

Never used azureus but if it's a network issue then maybe I can help Can you access the net fine? DNS is working properly and the correct ports are forwarded on your router? Does the linux and win32 port of the software use the same TCP ports for traffic? That's definitely soemthing to check out.

If you have a router or a hardware firewall, you do not need a software firewall. BitTorrent uses port 6881 through 6889 to transfer and recieve data. In azureus you may have to adjust the upload and download speed. When you are downloading, you may want to lower the upload speed. If you are uploading, lower the download speed. Probably you are not uploading or downloading from people with huge pipes.

With Azureus I can upload about 100 KB/sec (about 1.56 times of my upload bandwidth). This is same if it upload to my data server.

I heard some problems with some distributions with slow network problems. You can try load the ip6 module and see if it fixes the problem. I do not know why using ip6 module helps because you need an ipv6 network to make it work.

Of course. Linux is not any different then Windows. Also its not any different than Mac. The only thing that is different how the OS sets its network layer. Both Linux and Mac has a similar network layer setup, but Windows is very different.

I didn't know Azureus was bit torrent software, naturally all systems use the same ports then. I assumed it was something like kazaa, my bad.

Are you using a router by any chance, if so you need to enable port forwarding. I can't remember the exact port that Bittorrent or Azureus uses but you can find it somewhere on the web.

for the sake of consistency....if you are using Azureus 2.2.0.0..

go to tools>options

this will bring up the configuration options, in the top box you can select a port for the incoming TCP listen port. select a port and hit save.

I will use port 21212 in this example.

Now you would port forward port 21212 tcp/udp in your router to the ip address of the linux box.

Then make sure that in your firewall configuration on the linux box that port 21212 tcp/udp is open, allowing traffic.


Voila', you are all set. If you still get slow connection speeds it is the tracker that is moving slow due generally to a small # of seeds, keep in mind that you will always move slowly until you have a 'piece' then the torrent will speed up.

hope this helps,

Azureus doesn't use UDP only TCP, ports 6881 - 6889 can be used and you have to forward the tracker port which is 6969.

Ok thanks for all the replies
Yes I am using a router, with a hardware firewall, virtual server is setup for ports 6893 to 6896.
Azureus is setup with 6893 as the incoming listen port.
I don't get full p2p on any torrents despite this, and I know i should because I have tested them in windows with azureus, the problems i am having have got to be either to do with v2.2.0.0 of azureus since i am using 2.1.0.4 in windows (haven't had time to maintain windows with all the linux newness to deal with) or something to do with linux net connectin or its firewall.
Is the linux firewall like the windows xp firewall v1, i.e. is it incoming traffic only, because it seems to have rudimentary program access control or probably selected port access control.
Are you sure about tracker port forwarding? Never had to do this in windows before.
Okay so I said I'm using 6893, but how do I configure the firewall to allow this since I only have the firewall that came with the distro

yes it does use UDP by default, look at your settings powaddha, the little box that says enable UDP tracker client protocol is checked by default in 2.2.0.0(on the options page).
