transmission blocking my network?

hello

i have a problem with the transmission plugin, it seems that whenever i start transmission it blocks my entire network to the outside world and my router, however omv web gui can be reached without problems, if i pull the plug on the machine the rest of my computers on the network can use the internet again.

it all started very wierd and i belive it was around when i downloaded an update for transmission in omv web gui, i tried reducing allowed bandwith and connections and i even tried to reinstall the machine with fresh omv with no avail ... as soon as transmission starts, it will just block internet connection for the rest of the network.

im not sure why this is happending as it has been running just fine untill now with the default settings, it just sort of started suddenly after latest update, i remeber also changing some settings for turtle mode lately, but my guess is thats unrelated?

i attempted to install deluge to test if that works, but aparently it wont install on my system (not sure why, but could be related to some packages i installed after, that is unralated to my problem tho as these packages was not installed when i was testing).

afaik i dont get any errors anywhere it just seems it suddenly starts chokeing the network, has anyone else had this problem or does anyone know a fix for this?

I remember a similar issue around two month ago as soon as the omv was plugged the whole lan went down. No transmission there. The cause of the issue at the end was a faulty nic IIRC.

Transmission update if I remember was and update on the plugin not the actual binary.

Can't find the thread now. But you can replicate omv in the network with virtualbox and bridged adapter to see if it has the same behaviour as the physical one with transmission.

if its not transmission, then im quite surprised as everything works perfect when i stop transmission, as soon as i start transmission and it starts connecting, network chokes ...

Ok. As soon as you start the torrents are they actually downloading? can you access the webUI in omv or transmission to see how much overall bandwidth is consuming?

ill just test that to figure how much it is actually using, but i reduced the up-/download to 1500kbps (i have 90Mbit internet connection), i even tried 256kbps and yes i can wierdly enough connect to omv and transmission web gui just fine (not my router tho), while it blocks everything outside my local network

for some reson deluge halts here:

Reading package lists...
Building dependency tree...
Reading state information...

or i would have tried to switch that too ..

Can you post here cat /etc/transmission-daemon/settings.json this is the only way we know if the plugin is passing weird configuration into the daemon

just one torrent in queue will do the trick, not sure how or why this happend, it just happend one night while i was doing something else and it suddenly blocked everything for me.
at first i assumed it was an internet outage, untill i contacted my isp and they said "try stick the cable directly into a computer" ... i feelt rather stupid when i got connection right away.

..then i was wondering a bit about what could be wrong untill i tried removing the cable from the omv machine and voila, perfect connection again, connected it again and instant intenet block.

then i tried disable one service after another untill it stopped and as soon as i stopped transmission everything was fine and i could enable everything else again ...
as far as i can see nothing should be wrong, only thing im really sure about is this happend after latest update and/or changing settings with turtle mode (not sure how any of that could have this effect tho).

it worked perfectly fine untill this ... now its messed up even with a fresh install.
really dont get it ... ill try install deluge from command prompt as you said tho and see if that works, if it does ill be quite baffled but happy ...

edit:
aparently i must have broke some dependencies when i installed glibc 2.19 ... ill have to revert back to a earlier backup to test that.
unfortunatly that has nothing to do with my current problem, as i know for sure that it didnt work before i installed that either ...

i asked the isp when i called them and acording to them they arent blocking any ports nor throttling anything ... i was kinda hoping someone else here had a simmular problem and possibly a fix

What type of internet connection do you have?
In case of ADSL you should limit upload transfer to at least half of your max bandwidth.

afaik you cant get 90Mbit adsl, for the record i have fibre net 90/90 and as you can see in my settings im not using anything near that.

There is a utility called nethogs. It can narrow bw usage by process in Linux. You can log in ssh and check if transmission is sucking all bw when is working.

ill try nethogs, but what will it tell me i dont already know?

for unknown reasons it now seems to work fine again, im not sure why or how it happend, but ill be sure to keep an eye on transmission next time i have any network problems

edit:
thanks for the help, anyways
