Re: How to test how many connections are being reset by RST pack
Anime fansub "H2" has been running for the last 38 hrs., 10 mins. Only 67.3% complete. Connected to 22 peers, 4 seeds. Running at 23KBps down.
Anime fansub "Zombie Loan" is complete, but share ratio is at .886. Took 1 hr., 13 mins. to download 171.49 MBytes. Currently connected to 33 peers.
In that same 38 hour period I have downloaded probably 6, or 7 other shows at ~171MBytes each. Two, or three completed in under 20 minutes.
The box was rebooted some time before I started downloading "H2", which is a 41 episode series; 9,488.64 MBytes for the whole shebang.
The combined upload is roughly 43KBps; which, I think, is about right for a 512kbps DSL upload (512*.85/8?) The SpeedStream 4100 reportedly has a built-in QoS priority for outbound ACK packets, so saturating the upload has minimal impact on download.
I have no idea why so many resets.
Not counting stuff happening on the LAN, of course. A mail server running on another computer, with twice daily access from this one. Web surfing. Email testing to off-site servers for helping poster in Usenet groups. Downloading Usenet headers...

Those are some really, really, really strange numbers. 
You've had 1,737,538 successful connections.
3% Incoming, 97% Outgoing
95% were terminated by the RST flag (instead of FIN).
What the heck are you doing that makes 1.7 million outgoing connection attempts? How many years since the last reboot?

Two torrents running. AT&T is not (AFAIK) running Sandvine (or Ellacoya):

said by macguy  :Anyway I could test this in the os X terminal? I tried, but entering netstat -s find "rest connections" didn't give me any data that said anything about active opens or passive opens or anything else that your post said to look for. Try netstat -s | grep "connection resets received"
If that doesn't work, it's because I got the string "connection resets received" wrong. Just do a netstat -s and look for something like:
Tcp:
79600 active connections openings
35524 passive connection openings
12573 failed connection attempts
5257 connection resets received
