Torrent downloads terrible slow in Ubuntu 7.10
 

I tried bottornado and bit torrent clients and still the downloads take for ever to start and download extremely slow or don't start at all. I boot back to windoze and utorrent make the torrents fly.
i am using ndiswrapper for the wirelles nic.

any tips for any routing settings?

ip address is same for win and ubuntu on my wirless router.

thanks for the help.

if nothing else is slow then it's most likely your bittorrent client. Have you shared enough for your client to ok the higher downloads? If your BT client is based on the sharing mentality then the more you share the more you can take.

I think I never limit the upload because of this, I was told from another forum to open the ports using a gui for iptables I guess,
firestarter which is in synaptic's repos

if you don't have the gui installed did you set up iptable rules? Ubuntu enables iptables by default however there are no rules. You might be wide open already.

/sbin/iptables -L

I just maxed out the upload and download rates and this seemed to work!
installed firestarter but didn't need to use it. Thanks everyone!

Partial Solution
 

There is a couple of hints for the low download rate problem in Azureus/Ubuntu:

1. Make sure you are using Java JRE or Java JDK instead of GCJ/GIJ. You can install Java JRE with Automatix. Also, check if you are using JRE with the following shell command:

sudo update-alternatives --config java

2. Disable the ipv6 protocol as described in help.ubuntu.com/community/WebBrowsingSlowIPv6IPv4:

a) Open a terminal and type:
gksudo gedit /etc/modprobe.d/blacklist
b) Add this line:
blacklist ipv6
c) Save the file and restart your computer

3. Set Azureus' parameters for working with your correct internet connection:

a) Stop Azureus
b) Remove Azureus' configuration directory - in a terminal, type:
cd ~
\rm -rf .azureus/
c) Run Azureus
d) In the startup window, choose your internet connection type and speed

With these changes, I was able to improve Azureus' download rate by 2X to 3X. Nevertheless, uTorrent + Wine is giving me the highest (practically full) download rate.

Good luck

If you're on Comcast or another 'Traffic Shaping' isp they are killing your torrents. They are currently rolling out the SandVine product nationwide, one area at a time. What this software does is once they see the transfers being attempted, they make 2 counterfeit RST (reset) packets.. then they send one to you, spoofing the source to think it's the host at the other end, and one to the person on the other side of the connection, pretending like you sent it and are asking for a disconnect. I have found a couple successful work-a-rounds for this. The first is Enable Encryption on your torrent client.. (also this has to be enabled on both ends) if your client doesn't support it then get a new one. The second is to setup your iptables or router to drop RST packets. The second fix I mentioned I believe may cause some other errors but will still be fully functional. The only problems I forsee is that when a network service wants to send you an RST packet it will be dropped, so it will have to rely on the timeout.
