Something I've noticed about Ktorrent versus Azureus

I'm blown away by Ktorrent. It is light, fast, and I like the integrated searching. The search browsing does seem pretty limited so I often paste URLs from firefox where I can center click on a link and open a new page. This makes it easy to scrape multiple torrents from a list without having to page back all the time. To that end, I wish Ktorrent had a tool bar button for 'Paste torrent URL...'

I used to run Azureus. I like it real well. The thing with Azureus that bothers me is that if someone is bilching out a ton of bad data that Azureus is discarding because of failed hash comparisons, it still counts that data as D/Led data. This has prevented me from retrieving many torrents. I have a bandwidth usage limit and I can't give out bandwidth at 200:1. My ISP will shut me down. I believe this bad hash information is a DoS attach from the industry.

For whatever reason, Ktorrent works brilliantly. If I download something that's 1 GB and set the share ratio limit at 1.2, I can expect that download to cost me exactly 2.2 GB. It's a breath of fresh air.

One of the things I'm finding with Ktorrent is I've been having a hard time getting bandwidth from people. I can set an upload limit of 50 Kbps and it will stay nailed up but I'm lucky to average 1 or 2 Kbps download speeds. My firewall is still configured for Azureus. Do I need to reconfigure it for Ktorrent?

Is there a way to give preferential upstream bandwidth to applications that give me bandwidth? If someone has a high completion ratio and is sucking my bandwidth to the tune of 40 Kbps and has given me 0 bytes in return over 2 days, I'd like to ban them and never allow them again. Perhaps a lifetime per IP statistics based IP allocation feature would be good? We have to shut down the people who never share or bit torrent is going to stop working soon.

I can't wait for the new features. The to-do list has everything I would want in a BT client. This program is fantastic. Thank you very much for all the hard work that's gone into it.

KTorrent doesnt allow BitTyrant type choking where it highly prioritizes clients that give you higher speeds. This has been argued strongly to deteriorate an entire swarm at the selfishness of one person.

As far as consistently higher upload than download, that'll happen on starved swarms, but is pretty controlled. After a while KTorrent will stop sending the leech stuff until it gives back its share.

Thanks for the BitTyrant reference. I looked it up and am now running it. I like it.

After letting a torrent upload 3 GB.... when I only had 13 chunks downloaded (52 MB).... I have to abandon that technology. Seriously, that torrent will be long dead, the other peers will have had their fill, and my torrent will be stalled with no further seeds and 5% completion. If someone wants to pay my ISP bill, they can have my bandwidth. Otherwise, I only wish to seed to 3:1.

BitTyrant has been running for a couple of hours and I've got a ratio of 3.70. That's fantastic. This torrent might even finish in a couple of weeks. When done, I've set it to seed to 3:1.

You know... I feel like I'm doing my share for the peer network. I don't feel particularly selfish. I'm pleased to seed at a 3:1 ratio. ... but that's it. I would suggest it's time the jagoffs who seed at a 0:1 ratio were isolated and left to starve for bandwidth.

KTorrent has this option for a long time. You'll find it in 'File' menu.

One of the things I'm finding with Ktorrent is I've been having a hard time getting bandwidth from people. I can set an upload limit of 50 Kbps and it will stay nailed up but I'm lucky to average 1 or 2 Kbps download speeds. My firewall is still configured for Azureus.

Probably not. What version are you using? I suggest you try the latest 2.1rc1 you should have pretty much the same speed as in AZ.

I'd like to ban them and never allow them again. Perhaps a lifetime per IP statistics based IP allocation feature would be good? We have to shut down the people who never share or bit torrent is going to stop working soon.


This is also possible since 2.1beta1. You find 'IPFilter' option in toolbar and 'File' menu (don't mix it with IPFilter plugin - it's something else) you can right-click a peer and ban him - he'll appear in IPFilter dialog list. Then you can save this list on your HD and use it whenever you like.


To conclude, my guess is that you are not running recent version of KTorrent (or you didn't find those features we've talked about) so you should definitely upgrade.
