"Disconnect: Peer error: Error 10022"

[C-Otto]

Hi!

While trying to find out why my seeding client does not upload properly (a few MBytes in one night with a gigabit connection and enough demand, encryption is enabled) I noticed a strange behaviour with another client in my local network.

This client connects normally, receives data with good speed and disconnects after just a few seconds. µtorrent shows "Disconnect: Peer error: Error 10022" at the end.

Please tell me what this means and how to solve the problem.

Other clients often send "Got Cancel Unrequested: XXX:XXXXXX->XXXXX" and I also see many "Got Bad Have XXXX" (from my local client).

According to http://www.anzio.com/support/kb/Anzio_kb/Firewalls%20and%20winsock%20error%2010022.htm and other searches it looks like a firewall is mucking with packets. That logfile just shows you advertising pieces, and receiving piece haves from others. your client connected to a peer running libtorrent, sent it piece haves (i've got this do you want any), and GOT haves from it (i've got these do you want any). It appears you found your culprit. I'd example 1) the setup of that computer for software which mucks with internet packets and 2) the POP of your line to see whether or not there is a miscommunication there.

[C-Otto]

Thanks for your answer!

Why would libtorrent offer pieces to a seed?

How did I found my culprit? I am confused.

Both computers do not have any software that alters network traffic. Using tcpdump I just noticed wrong TCP checksums, which may be caused by the network card driver (good Intel card, e1000).

What is "the POP of my line"? I am German, please use common terms

PS: Both systems use Linux, I don't have any Windows machine here.

Bye,

AH, sorry. K, if this is all LAN traffic, are you using ipfilter/iptables to restrict access? :/ I don't know what else would be mangling packets.

Before when I was talking about POP, it's acronym for "point of presence"... basically where your ISP turns into your LAN. Your point-of-entry to the internet if you will. I hope that's a better explanation

You know that 137.x.x.x isn't a LAN IP. Is that your WAN (Internet) IP?

[C-Otto]

The problem with error 10022 occurs inside the LAN, yes. The thing you call POP would be a router in my case, but that machine is not involved in the traffic between the two nodes (but the tracker is outside, piratebay!). My ISP is my university, which has several other networks and routers between my "POP" and the "real" internet (starting outside of the university by my definition).

I do not restrict traffic at all, that includes iptables.

The IP mentioned above is routable from the internet, but of course also used in my LAN (which is 137.226.108.0/22, so 1024 "internet" IPs). Both machines I used are in the same subnet, so traffic flows without any router/firewall/POP/...

Thanks,

I'm encountering this error in much the same way as C-Otto has experienced. This occurs on uTorrent 1.7.7 running through wine on my linux box (all appropriate ports opened in iptables). Usually a peer connects, downloads a couple of MB's, and then suddently disconnects with Peer error 10022 according to the log. The system is on a 100/100 connection, and this mostly happens when other fast peers attempt to connect to me. Is there anything I can check to make sure that my system isn't the culprit?

[UncleBob]

I dunno if you have already solved the problem, but it's a bug in wine. It makes utorrent drop peer shortly after it got connected if the peer is downloading at speed more than about 0.8MB/sec. This bug exists in wine versions from version 0.9.40 to 1.1.5. Every version below/or above has no this bug.
