Hello. I upgraded my cygwin packages recently and have started getting problems with ssh connections terminating unexpectedly with the following message: Timeout, server not responding. This only happens when sending/receiving a burst of data at once (i.e. typing single characters etc works fine). I can consistently reproduce this for example by doing the following: ssh user AT otherhost DOT com ls -lR / It will dump several screens worth of directory listings and then die unexpectly with the above error message. I can also make it fail sending data as well - for example, by cut-and-pasting a chunk of text into the ssh session. I believe this problem may have something to do with the way interactive ssh sessions are managed, because it does NOT occur when simply executing non-interactive commands. For example, the following command consistently works fine!: ssh user AT otherhost DOT com ls -lR / I have tried reinstalling the packages and have tested this with both OpenSSH 4.5 and 4.6 packages and they exhibit the same problem. I know it is not a network adaptor issue because an equivalent SSH session with Putty works fine. Does anyone have any idea what might be causing this? (I am running WinXP SP2) BTW I don't know if it is related, but I also recently started getting problems with ssh-add (before these dropouts started occuring): $ eval `ssh-agent` Agent pid 3208 $ ssh-add Enter passphrase for /home/Scott McNab/.ssh/identity: Error reading response length from authentication socket. Error writing to authentication socket. Could not add identity: /home/Scott McNab/.ssh/identity I can live without ssh-agent however the constant terminal dropouts are a real showstopper. Thanks in advance for any insight you can provide!
