This is a weird problem: I have a very large file (backup for my machine) that I'm trying to rsync over to a remote host. The file transfers to a certain point and then just stops. I've tried the transfer with SCP and it stops at the same point. Other similar files (other incremental backup files) transfer fine, so it seems to be specific to this one file. I've done a packet capture on the transfer and when it occurs the receiving side simply stops responding to the TCP packets and the sending side starts going into exponential backoff and retransmission. This is 5.1p1 on both sides, although the sending side is Ubuntu 8.10 and the receiving side is FC9. Does anyone have any suggestions for tracking this issue down? The receiving machine isn't mine, although I can probably get the admin there to help with debugging sshd if that would locate the issue. I know this sounds silly but it reminds me of the good old days of analog modems when someone would accidentally send "+++" down the line and escape out the other side (hope no one's reading this over a modem :) ). Thanks, Derek
