I'm trying to capture some large files from my house (on Comcast) to a server out of state (not on Comcast). I'm copying the files using ssh and a non-standard port.Things are fine for files of a couple megabytes, but files over say 10 megabytes stall out part way through. One night I got 50MB uploaded all night! So today I started up tcpdump on both ends and captured the traffic. I noticed an interesting thing in wireshark when the connection stalled out. I got a "TCP Previous segment lost" message on the server side and then started getting "TCP Dup ACK" on both ends. The server has a SonicWall firewall in front of it and is virtualized with vmware. My house is using dd-wrt on a Linksys router as my connection. Is this Comcast doing it's filtering for our protection or is this just something misbehaving on either firewall? -- Jon Schewe | http://mtu.net/~jpschewe If you see an attachment named signature.asc, this is my digital signature.
