I have started using Shareaza, its ok sometimes. I think i have caused a DoS on my own connection and too myself by setting the number of transfers, files and files per transfer too high although I'n not sure what they where. I was trying different settings to maximise throughput(download) and something happend i don't understand.
Basically the transfer monitor in Shareaza was showing very low transfer rates (relative) and the u/s was maxed out causing loss of connectivity to everything - other than whatever it was doing.
My netstat. This isnt the full table, its minus the standard stuff you always see above and below the active conections:

Port 6347 is the port used for Shareaza. I'm not sure about the 2* port numbers. At the time upstream was leaving this machine at max (32kBps) and a similar speed on d/l. Shareaza showed u/s and d/s speeds of 14kBps (ish). Hmmm, way off.
When i closed Shareaza the transfers stopped and the connections closed.
FYI: I'm running Norton Internet Security '02 and behind a NAT forwarding 6347 to m081e.
I dont uderstand p2p much or the networks they operate on but it would be nice to understand why this happend so i can avoid in the future and configure properly.
Cheers guys,
John
