Subject:	ssh error 'The descriptor is a file, not a socket'
Date:	Thu, 1 Nov 2001 16:30:28 -0700

Hello,

I'm trying to use cygwin's sshd to allow my Linux box to log into my win98
computer using the 'ssh host' command.  The authentication goes OK, but
after 'entering interactive session' I get the following error on the client
side:
	'getpeername failed: The descriptor is a file, not a socket'

I've also seen 'getsockname failed: The descriptor is a file, not a socket'
with some variations of the ssh command options.

On the server side, running with 'sshd -d -d -d' I see debugging messages,
what I think is the possibly-relevant part is at the end of this message.  I
notice some 'unsupported opcode' errors after 'session_pty_req' that seem
suspect, but I'm not sure really what to look for:
	'Ignoring unsupported tty mode opcode 52 (0x34)'
	'Ignoring unsupported tty mode opcode 62 (0x3e)'

I noticed a message from Jeff where he has the same error with a recent
snapshot version of OpenSSH.  I am running OpenSSH_2.9.9p2 and Cygwin 1.3.3.

Thanks for any help,
Kris

P.S.  Here's the other sshd debugging output that may be relevant:
