Hello
I was using T (GTK) on Ubuntu 12.04. no problems for 2 years. Then last night I started T, but returned error: 'Could not connect to tracker'. I shcekc port: open. I powered up ktorrent: it works no problems - downloads and up loads. I uninstalled T and reinstalled. I increased cache from 2 to 4. Still, no fix. I've checked forums - this problem pops up a lot, but there does not appear to be any solution.
Most obliged for any ideas.
