Re: How to test how many connections are being reset by RST pack

TCP Statistics for IPv4
 
  Active Opens                        = 1683318
  Passive Opens                       = 58529
  Failed Connection Attempts          = 4309
  Reset Connections                   = 1651849
  Current Connections                 = 42
  Segments Received                   = 49963488
  Segments Sent                       = 38610912
  Segments Retransmitted              = 26816776
 

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?

Are you affected by Comcast's RST forging? How to test it! -or- Read my original report.

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...
