ktorrent downloads everything fine & fast
but nothing is uploaded
i updated from 3.1.2 to 3.2.1 - no result
router: dlink dir-855
dhcp - disabled
ports forwarded: 6881 tcp; 4444 udp & corresponding settings in ktorrent
(i`ve tried 6800 & 4400 - it didn`t work either)
upnp - disabled (enabling it didn`t bring up any result)
ubuntu firewall - disabled

requesting reinforcement

Are you connected to any peers when a torrent is seeding ?

how to check it out?
in the speed charts # of peers are somewhere around zero
in main window # of seeders & leechers are zero (very seldom 1) too
but, during download there are a lot of them only for downloading file

Nobody to seed to, so no seeding is done, pretty logical isn't it ?

it is
but how am i to fix it?
because files i`ve downloaded are popular ones
under utorrent on windows they are uploaded pretty fast

is it, at least possible to check,
which port ktorrent is (trying) using now,
or test active port?
