Win2000SP2 CYGWIN_NT-5.0 1.3.6(0.47/3/2) 2001-12-08 17:02 i686 unknown
OpenSSH_3.0.2p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f

Open a Cygwin command shell (my default is configured to 80x45)
ssh to a RH Linux 7.1 box
Change the window size to, say, 80x60
Run the 'resize' command (on linux host)

The text cursor jumps to the bottom-right corner of the window
(this is normal) and just stays there (this is not normal).
resize never returns.  This behavior ALWAYS happens even if
I don't physically resize the window (i.e. run resize
immediately after logging in and it still hangs).

I've tried setting TERM=ansi, TERM=vt100 and TERM=cygwin
in the Linux shell with identical results.

If I logout (back to cygwin shell) and re-ssh from
the resized (80x60) window everything works and the
COLUMNS and LINES environment variables are correctly set.

As I understand it, resize sends a specific terminal control
sequence that requests the hardware to reply with the current
size.  I assume that either cygwin's bash isn't playing just
right, or something gets garbled over ssh.

As a side note, I tried running resize locally (in the
cygwin bash shell) and it fails looking for cygncurses5.dll,
which is not in any of my bin directories.  I did find
cygncurses6.dll in /usr/bin.  Is this related or just a
coincidence?

Suggestions on how to debug this further?


Did you see this?

I'm not sure.  If the resize command relies on OOB transmission
of the terminal dimensions, then it's most likely the cause.
I'm not enough of a tty/ldisc/protocol hacker to know the answer.

Thanks for the pointer, though.  I would never have found it
by myself :-)
