I get similar symptoms with unison over ssh:
It worked great before SP2 (i.e. 2 hours ago).
After I installed SP2 on the client, unison/ssh just hangs.
The server has been running SP2 for over a week.
Any normal ssh sessions work fine. I'm also using ssh to forward the
IMAP port (143) to my server's port, which still works.
By adding -rshargs "-vvv" to unison, the last few lines of ssh debug
output is:
Contacting server...
...
debug1: Authentication succeeded (publickey).
debug2: fd 4 setting O_NONBLOCK
debug2: fd 5 setting O_NONBLOCK
debug1: channel 0: new [client-session]
debug3: ssh_session2_open: channel_new: 0
debug2: channel 0: send open
debug1: Entering interactive session.
debug2: callback start
debug2: client_session2_setup: id 0
debug1: Sending command: unison -server
debug2: channel 0: request exec confirm 0
debug2: callback done
debug2: channel 0: open confirm rwindow 0 rmax 32768
debug2: channel 0: rcvd adjust 131072
... and nothing more happens.
For the record: My unison is 2.9.20, Win32 native, *not* the cygwin
port. cygwin and ssh were already up to date, as of 3-4 days ago.
Cheers,
Rob
