Windows / Re: QBitTorrent breaks Internet AND LAN traffic, plz help me troubleshoot

Re speed: Yes - I have Internet through the cable TV line delivering 500 Mbit down / 50 Mbit UL. I get they speed they offer in connections to most locations, so in general I am quite happy. Full duplex Gbit fiber would naturally be better but since fiber is not an option this is not too bad imo.

When it comes to upload-side possibly black-flooding: Could be, although as in most scenarios on private trackers I get almost full throughput the moment I start download while the upload traffic is more sporadic and fairly low in general. What I mean is, if this was the case it would make more sense if the problem manifested when upload speed also came close to max right? During my single torrent test yesterday I barely had any upload traffic at all while network was cutting off.
Were you only downloading from a single ip address using a single ip-to-ip connection, TCP/IP networking overheads might be ~3%. But networking overheads go up at least slightly with the use of additional connections. Peer/seed downloads have the BitTorrent protocol on top of that. Then there's DHT, LPD, and PEX which add a bit even if there's no downloading/uploading going on. Then there's incoming connections, which can be pretty intense if you're running lots of busy torrents and many of them are doing multiple round trip encrypted handshakes. Lastly, there's outgoing connection attempts made by qBitTorrent, which is overwhelmingly upload-based and continues even when no downloading/uploading is going on. Adding up everything qBT can be doing, upload bw usage can be 10-25% of the total download speed.

10% of 500 mbit/sec down is 50 mbit/sec up...all you have.

"I can try to set up another laptop on cabled Ethernet to switch and run a ping-test next time I start torrents"

If that's not a lot of trouble, please do. I wouldn't be surprised if the Cisco switch keeps working but the Asus router goes down. There might even be a broadcast/multicast storm or something else exotic going on, which saturates the bw of the network.

So before giving up all hope, test as well with DHT, LPD, uTP, resolve ips/country flags, Tracker FavIcons, and internal tracker all disabled.

Windows / Administrate RSS using web interface
« Last post by Anders on November 17, 2017, 06:49:50 pm »
Hey guys.
Can you somehow administrate/add/edit RSS feeds through the Web interface?
I run qbittorrent as a service and not very nice to need to stop the service, start it in desktop mode, change settings, close desktop mode and restart service

Windows / How to skip the torrent added window for RSS downloads ?
« Last post by cnckane on November 17, 2017, 06:18:34 pm »
Hello,
I just started to use the program. Everything works fine, just couldn't find one feature that was present in uTorrent.
I have one RSS feed and download torrents from there regularly - by manually selecting some of them (making a rule for auto download is not possible). When I selected more torrents from the RSS list utorrent automatically added all of them without asking any question and used the feed name as Label -> SubFolder to save it.
So if I create a "myfeed" RSS and manually select torrents from there utorrent automatically added all of them to the download list under "myfeed" category. Would be possible to do the same with qBittorrent ?

Windows / Re: Is it possible to have a global upload speed per torrent?

Bumping this. Any updates regarding this feature? I wouldnt even mind if it was possible to accomplish this with a script or something.

Is this a horrifically asymmetric internet link -- 500 mbit/sec DL and 10-50 mbit/sec UL?

The upload-side back-flood while downloading at 50 MEGABYTES/second could be overloading the internet connection and causing the modem and router to quit responding due to bufferbloat, filled buffers, and broken firmware. But that still might not explain why the server couldn't be pinged by the desktop through the supposedly more reliable networking switch.

It would be interesting to test a 3rd device plugged into the switch while under such loads. The server may be hosing itself due to its own networking problems, so pinging a 3rd device on the same switch as the desktop could rule out the switch "dying" under such loads.

Hi and thank you for your reply.

During my single torrent test yesterday I barely had any upload traffic at all while network was cutting off.

Yeah it's all very, very strange to me, and I consider myself to be fairly skilled on networking etc: My switch (cisco 8-port Gbit) should not break down if ISP modem or router was overloaded. I have a connection directly to my server on RDP, and it breaks (along with other network traffic) when everything stops.

Regarding testing a 3rd device plugged into switch: While testing before starting new torrent I was pinging the Asus router, server + Internet IP from my cabled desktop computer connected to switch. All 3 stops responding. At the same time I was pinging an Internet IP from my WIFI laptop, which stops responding & comes back at the exact same time all other network traffic is jammed/comes back. I also see that the server lost Internet connectivity because qbittorrent starts to pick up downloading again, from 0KB/sec going up, once RDP connection from desktop computer to server resumes. So basically, after the testing above I know
-WIFI traffic going directly to Asus router dies. This traffic goes directly to default gateway (Asus router) and has nothing to do with Cisco switch, server or desktop computer
-LAN traffic between all devices connected to switch (Asus router, server & desktop computer) all dies

In one way or another, something during qbittorrent downloads breaks connectivity to/from both Asus router AND Cisco switch, at the same time. I can try to set up another laptop on cabled Ethernet to switch and run a ping-test next time I start torrents although I would expect it to have the same result.

Generic / ban a range of ip#
« Last post by anotherkat on November 17, 2017, 02:56:48 am »
I have been using qbt for a few years and have a huge thorn in my side. There's a peer who has a range of ip# they can (and do) use, and each time they pop up i can usually ban them manually. So find out qbt cannot ban a range natively, but can using a filter text file along the name of ipfilter.dat, composed easily with any text editor. So i look at some of the same format, and make a file with one entry, but for this forum i will use bogus numbers...

001.000.000.000 - 003.255.255.255 , 000 , badperson

I save the file, i click reload icon on qbt 3.3.3, it says it loaded and parsed ok. About 30 seconds later, i see a peer using ip 2.35.67.90. Obviously, this didn't work. So i edit it:

001.000.000.000 - 001.255.255.255 , 000 , badperson1
002.000.000.000 - 002.255.255.255 , 000 , badperson2
003.000.000.000 - 003.255.255.255 , 000 , badperson3

I save the file, i click reload icon, it says it loaded and parsed ok. About 30 seconds later, peer is back.

I tried closing qbt, making sure it's dead with taskmanager (windows vista), and restarting. Everything looks good. Except a few minutes in, i see badpeer.

The one IPFilter/BannedIPs line in qbittorrent.ini is 3.2k long, if i must add every ip for every block of ip this peer uses, that one line will be megabytes in length, and i expect qbt will barf on it.

Please tell me how to ban a range of ip in qbt !!!

A few posts on the subject of private trackers have been made by me. Try doing a search for them on the forum.

You're not the only one to have problems with qBT and private trackers:

Your maxspeed isn't reported to other peers/seeds.

A downloading Peer's conditions are more like what happens when 10 people try to download lots of stuff while sharing a single, slow internet connection.
