Ktorrent/questions
Chapter 7. Questions and Answers
[edit | edit source]What is this “port forwarding” I hear about, how do I enable it and why is it clever to use this?
[edit | edit source]Port forwarding will allow other computers to request a connection from you. In general it allows more connections as your machine is now able to both make and receive “phone calls.” If possible you should enable it, unless your equipment (computer, router, etc.) is adversely affected by the extra open connections.
What are the two most common mistakes by BitTorrent newbies?
[edit | edit source]The two most common mistakes made by BitTorrent newbies are not forwarding ports and not seeding torrents. If you don't forward your ports and don't allow KTorrent full access on your software/hardware firewall (if you have enabled one), you will not get the most out of BitTorrent. You can get help on port forwarding at portforward.com, and some (slightly technical) information is available at Brian's BitTorrent FAQ and Guide. Seeding is when you leave your BitTorrent client open after your download has finished to help redistribute it (you share the file a little while downloading, but it is even more helpful if you continue to distribute the completed file). It is most likely that most of the data you downloaded was from other seeders, so help give back to the community! KTorrent will begin seeding your torrents once they are completely downloaded, and will continue until the torrent is removed (right click the torrent, then click Remove). Remember that while seeding, KTorrent is uploading using your internet connection, and if your internet service provider limits the amount you may upload, you might want to monitor how much data and for how long you seed your torrents.
How can I check whether I have forwarded my ports correctly?
[edit | edit source]Check in the log viewer for Authentication(S) messages. If you can spot a single message with (S), you know you can receive incoming connections.
Can I use KTorrent to index and share a folder on my disk without creating a torrent file?
[edit | edit source]No. KTorrent uses the BitTorrent protocol, which does not use a global network like Kazaa. Instead, BitTorrent uses a separate network for each torrent file. To share a file or folder, you will need to generate a torrent file for the files.
Can I configure KTorrent to use a single port?
[edit | edit source]Yes. You can use DHT (UDP) on the same port as the normal TCP traffic.
Sometimes I see peers in my peer list with a low score. Are these bad leechers, and should I kick or ban them?
[edit | edit source]No. KTorrent uses a scoring system to calculate which peers are most worth uploading to. Peers not interested in your data will get a lower score than others.
Why is my download so slow?
[edit | edit source]The most common reason is that the torrent source is not shared well enough (the swarm is unhealthy). Another reason could be that you are not uploading fast enough yourself.
Why is there only a handful of peers in the swarm?
[edit | edit source]Every torrent depends on other users who are downloading the same torrent. You might find a torrent which does not have a lot of peers yet. Just let the torrent run and most of the time, it will speed up after a while.
I just added a torrent, but there aren't any seeders or leechers in the swarm. What is wrong?
[edit | edit source]Check whether the torrent was taken offline by the tracker. Some trackers send a message for this, which you can find in the trackers tab.
Why can't I configure KTorrent to announce every five minutes?
[edit | edit source]This is against the BitTorrent protocol. Every client should use the announce time supplied by the tracker in the announce response.
Some torrents have a longer announce interval. Is this a bug?
[edit | edit source]No. KTorrent uses the announce interval given by tracker.
My download speed is horrible! What can I do to improve this?
[edit | edit source]Every torrent depends on how many peers are in its swarm and how well they are seeding. Make sure you are able to receive incoming connections so others will be able to share the file with you. Also ensure you are seeding well enough yourself. You can check whether the torrent has a good potential by looking at how many leechers and seeders have joined the swarm.
I have generated a torrent file. What now? How do I share my data with a friend?
[edit | edit source]You will first have to upload a torrent file to a BitTorrent tracker. The torrent file should contain a tracker URL for it to work correctly, and some (private) trackers have a separate URL for each registered account so they can keep track of your traffic. After that, your friend can download the torrent from the tracker.
I have set the max connections to a few thousand, but no matter how many peers connect, the download is not any faster!
[edit | edit source]Speed does not depend on how many connections are established, but rather on how well peers are sharing a file.
Can I use KTorrent to send a file to my friend without having to share it with other peers?
[edit | edit source]Yes. Use 127.0.0.1 as your tracker URL and send the torrent to your friend. After that, add your friend's IP manually by right clicking the torrent and choose Add Peers.
I have configured NAT in my router to forward ports to my computer, but once in a while, peers are unable to connect to me. Can I fix this?
[edit | edit source]Most routers assign IP addresses by using DHCP, and most of them do not lock the IP address. Your computer might be getting another IP address, because another computer in your LAN went online. In this case, your router is still forwarding to the old address, which would be another computer in your LAN! To fix the problem, try using UPnP and the UPnP plug-in if your router supports this, lock DHCP by using your MAC address, or use statically assigned IPs on your network.
When I set my upload rate to a minimum, my download speed drops too. Why is this, and can it be fixed?
[edit | edit source]BitTorrent, as a file sharing system, depends on users uploading data. When you do not upload enough data to the swarm, other peers will not be willing to share data with you, and your download speeds will drop. If you are able to upload at a faster rate with your internet connection, you should set the upload rate higher and make sure you seed your torrents after they finish downloading.
I have set KTorrent to use 120 upload slots, but my download is only getting slower.
[edit | edit source]If are not uploading enough, peers will simply ignore you even if you have enough slots. Check that you have set at least 2kbit/s per slot to ensure peers will receive enough data.
Can i download or seed a torrent from my USB stick with KTorrent?
[edit | edit source]Yes. But, іt can damage your USB flash drive. And the flash drive has a small speed.
I want to seed data from my NTFS partition, is this possible?
[edit | edit source]Of course. There are no restrictions on the file system at the program level, if the system is supported.
Why does the tracker tab sometimes tells me that I can not add another tracker to the torrent?
[edit | edit source]because the torrent is private, and you can-t add DHT or another tracker.
I would like KTorrent to seed an existing torrent. How should i do this?
[edit | edit source]aa
Why does KTorrent not let me download to NTFS and FAT32 partitions?
[edit | edit source]You need to disable diskspace pre-allocation for this to be possible. NTFS has removed this problem for today.
Why does KTorrent not let me use the zip file from bluetack in the ip filter plug-in?
[edit | edit source]Kdebase-kio-plugins is required to extract the zip file, so check whether this is installed.
