How to fix transmission unable to download and connect to torrent tracker on Ubuntu Maverick 10.10

As you can read in my few previous posts I have just installed a new Ubuntu 10.10 on a Toshiba Satellite L40 notebook.

Most of the things which are necessery for a fully working Linux desktop are already installed and the machine works fine, however I just noticed there is an issue with the default torrent gnome client and transmission unable to download files from torrent trackers.

Few minutes of playing with the transmission’s settings has revealed what was causing my torrent download problems.

It seems on Ubuntu 10.10 (probably on other Ubuntus and Debians) by default the transmission bittorrent client is trying to use for torrent download connections an incoming port 53636 number.

As the computer is behind a firewall and does not have a real IP address seeders cannot properly connect to the notebook port 53636 and hence the transmission bittorrent client could not initialize any torrent downloads.

Fixing up the issue is rather easy to fix it I had to change the settings in transmission from the menus:

Edit -> Settings -> Network

You need to select the options:
 

  • Pick a random port on startup
  • Use UPnP or NAT-PMP to redirect connections

Next I had to restart transmission and my torrent downloads started 😉

    i put a tick on “randomize port on launc” but still says port is closed. i restarted transmission after this and still nothing.

      Hmm strange … maybe you have some strong firewall before your pc? Try if you have the same problem with some LiveCD or LiveUSB of different GNU / Linux distribution if you’re on Ubuntu.

      best!

    Thank you heaps aye. 12.10 Ubuntu.
    Restarting Transmission didn’t work, but eventually came through after a reboot of my whole system. Now working like a charm.
    Thank you again.

    Thanks, it worked.

    In Transmission Options-Network(WAN), select " pick random port at startup". I rebooted my raspberry pi.
