tcp/ip connection limit reached

Post by enderzero »

If you weren't aware, with SP2 Windows has been limited to 10 TCP/IP connections per second (from SP1's unlimited). This can result in a slow ramping up of torrent downloads. There is more info and a fix at speedguide.net.

Yeah I saw that a few months back, didnt really look to much into it.

10 connections per second is enough for me.
TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

Yours may be more affected by the UW network and all the sniffing they seem to do Danz. McNevin knows a thing or two about their setup and may be able to fill in some blanks.

Well it has been 6 years; they didn’t have an anti-bit torrent dept back then.

If you are continuing to download torrents, despite your warning, I would probably install "peer guardian." http://methlabs.org/methlabs.htm

Peer guardian was recommended to me by the ISP that I work for. I talked to our security department, after I was busted, and they said this should do the trick.

Have you tested the speed caps you getting in your dorm? They have several T3's but I doubt they would not limit the student's connections a little. I would try and find your maximum upstream bandwidth, and then cap your BT upload at 80% of that. I set mine really conservatively at 60%, but I have a pretty low upstream.

thanks...

errr...I am not as computer savy as you guys, so how do I do all that fancy-shmancy testing and caping...

I am not using torrent to download illegal stuff these days...mainly just music from etree.org

what exactly does methlabs do?

The methlabs peer guardian has a list of anti peer to peer baddies, and it blocks any transmission to those addresses.

What i did was go to http://speedtest.dslreports.com

Their speed test gaqve the following results...

Your download speed : 2790966 bps, or 2725 kbps.
A 340.6 KB/sec transfer rate.
Your upload speed : 363442 bps, or 354 kbps.

So my upload is 354 kilobits, so then convert that to bytes 354 / 8 = 44.2 Kilobytes Per second.

Then we want to get 80% of that, 35 roughly.

In your BT client you will see maximum overall upload rate somewhere, force that to XX, in my case it was 35. You should see some improvement.
