Problem with torrents.

English Network/Internet
1

Hi! :slight_smile:

I wanted to download a distro in order t test it, so I decided to setup my torrent stuff.
I set a static ip, I opened the related ports at firewall and I configured 2 torrent clients (Azureus and KTorrent), just in case.

The problem is, that when a torrent starts downloading, after a while (lets say at 1.5% of download completion) every traffic stops.
The problem occured at both clients (Azureus and Ktorrent), although they are indicated that can accept incoming traffic (Green. Not “firewalled”).
I disabled the firewall (just in case), but since this was not the source of the problem, nothing changed.

I’m using Open SUSE 13.1 x64 KDE.
Any hints?
TIA! :slight_smile:

I have recently downloaded several files with “ktorrent” (most recently the Fedora 22 iso for the KDE spin).

I did not open any firewall ports. I did not set up any port-forwarding on my router.

It just worked.

Oh, I forgot to mention!
Router’s port forwarding was already set, from earlier days.

Ehm…here is just refusing to work! :slight_smile:
Seems like it’s just me…:slight_smile:

Maybe a review of the entry concerning the forwarding rule on the router itself might be warranted.
Follow the router’s procedures for configuration changes (probably save and reboot of the router),
re-create the entry. Who knows? May as well rule it out as the cause.

My attention was drawn away and I inadvertently posted an unfinished post. Here’s what I meant to say.

Maybe a review of the entry concerning the forwarding rule on the router itself might be warranted.
Maybe you might decide to delete the concerned rule.
Follow the router’s procedures for configuration changes (probably save and reboot of the router),
re-create the entry. Who knows? May as well rule it out as the cause.

Years ago I wrote about this,
What is happening,
Why it’s happening,

And the solution which is to change your TCP Collision Control Algorithm… The default installed is for highly reliable wired connections over short hops. If you’re using any kind of wireless, opening larger numbers of simultaneous connections, have RF interference and more, then the default is not appropriate and will cause problems.

I also describe how to enlarge your TCP buffers if desired… which generally depends on available system resources and whether you’re running a number of heavy load apps or just a few.

Although it was written for an earlier version of openSUSE, AFAIK everything in it is still as relevant today as when it was created.

@kerijan:
No, reseting the router doesn’t changes something! :frowning:

@TSU
Thanks! I’ll try it! :slight_smile:
