Oh
Also I dont think the winXP firewall is on, but Im not sure.

Thanks

if you have yellow light then you have a NAT problem,that is a router or firewall problem,to check if you have the xp firewall on you go to Start then Control Panels, then internet connections tab, then clicked on Advanced on that page, and finally under security or firewall or something you'll find something where there's a check box to turn off the firewall.

about shields up
If all your port displayed as green => "stealth" => you are behind firewall or proxy server. It should all comes out as red => "open" => you are not behind firewall/no protection between you and the internet.

Thanks

Try go to http://grc.com , then select "Shields Up." You'll be able to test your "Common Ports." If you are not behind any firewall or NAT, it should showed "open!" . Also, you can tell it to probe port 6881-6889 using "User Specified Custom Port Probe" option.

about the ports 6881-6889 ,thats what azureus used,actually now it use one single incoming port and thats port 6881

I can get a few hundred down and only can only all 13 up. If I leave it on cable fast I'll wind up getting capped from my provider at 128k instead of 1mbit.

You simply cannot exceed the speed of your connection -- especially on uploads -- without BAD things happening. Even if your ISP doesn't further cripple your connection, pushing upload speeds to absolute max only results in hideous download speeds and ironically REDUCED upload speeds compaired to 'nearly max speed' uploading.

I am not asking you to upload at 'unlimited' speed -- I highly recommend AGAINST using that setting.

I in fact think it is BETTER to be using super seed mode and 'average' (maybe half max for your connection -- or even less) upload rate over a LONG period of time rather than using normal seed mode and a faster upload rate for a shorter period of time EVEN THOUGH in the second case you upload MORE. This is because with super seed mode you are giving the NEEDED parts to the swarm of downloaders to share among themselves. With regular seed mode, you may be uploading the same parts multiple times to different users while they NEVER get the missing parts they all need before you reach 1:1 ratio for uploading to downloading.

Note that with LOTS of downloaders/peers and many distributed copies between thm, super seed mode DOESN'T work well. It's when the number of downloaders is few and/or a FULL copy of the file cannot be created by them sharing the parts they have that super seed mode is really needed. If there's lots and lots of downloaders, you'll end up sharing 1/10th of a chunk to lots of users and they won't be able to upload ANY of it till they get a complete chunk.

File chunks are typically 256 KiloBYTES in size, although they are often larger for movies. Even at 10 KB/sec upload rate to 4 users, splitting that equally means they each get 2.5 KB/sec. So it takes about 1min 45sec to send out a chunk to each person -- however BitTorrent likes to 'jump users' on uploads a LOT if there's lots of users, so it may take considerably longer before you send the 1st chunk to ANYONE. Until someone gets at least 1 COMPLETE file chunk that somebody else needs, they will not upload anything.

Even a 1:1 upload:download ratio is only a general rule. Some torrents have SO MANY seeds that you can't upload fast on them because all the peers/downloaders are maxed out in speed! Others need far more uploading JUST to keep those torrents alive! I try to keep my upload bandwidth at least 75% used even 24/7 -- since I cannot save it up and it's separate from my download bandwidth.

For those with bandwidth daily/monthly caps, I recommend uploading at a (much?) reduced rate but over a longer period. You don't have to upload 1:1 with your downloads, but you BETTER NOT exit the torrent (unless you're just rebooting and/or will return later) if there's no other seeds! At least make sure all the peers/downloaders have at least 1 (preferably more) distributed file copy between themselves.

Something new I've started doing is starting FINISHED torrents immediately after rebooting, because these can start uploading immediately while I search for and/or start new torrents. After new torrents start uploading, I either slow or exit these finished torrents so the new torrents can upload and hopefully download at full speed. Once again this is because I cannot save my upload bandwidth up for later use... so I might as well give away all I can.
