Hi

I have happily used Cygwin ssh from "DOS" command prompt for many
years but
on upgrading to V1.7 get this error message. Further info:

OS: Vista

/etc/passwd line:
tda:unused_by_nt/2000/xp:1000:513:U-laptop1\tda,S-1-5-21-2414507100-3802266639-3593817948-1000:/home/tda:/bin/bash






The interesting thing is that if I open up a second command prompt and run an arbitrary cygwin command (like "less filename"). ssh successfully finds /home/tda/.ssh (but only for so long as that second command is running).

I suspect this is something to do with the changes to mounts, but so
far I've
been unable to find a fix.

I think we need more information about what you're actually doing and what your configuration is. Please review the problem reporting guidelines found here:

OK. Steps to reproduce:


1. Open command prompt, type:
c:\ ssh fleet
Could not create directory 'c/.ssh'.
The authenticity of host 'fleet (192.168.1.30)' can't be established.
RSA key fingerprint is 17:33:a7:32:cd:e1:04:ed:d7:3b:dc:11:c6:da:3c:42.
Are you sure you want to continue connecting (yes/no)?

2. Open second command prompt, type:
c:\ less main.c

3. Leave less running, return to first prompt and repeat login attempt:
c:\ ssh fleet
Linux fleet 2.6.32-5-686 #1 SMP Tue Mar 8 21:36:00 UTC 2011 i686
(login OK)


cygcheck.out is output of cygcheck -s -v -r with less NOT running. cygcheck1.out is output of cygcheck -s -v -r with less running.

The difference below looks relevant:

cygcheck.out:
Output from c:\cygwin\bin\id.exe
UID: 0(tda) GID: 0(root)
0(root) 545(Users)

Indeed. Some thoughts:


1. Check that you're using Cygwin's ssh.

Yes, double checked.


2. Try unsetting "HOME" before running ssh.
C:\>set HOME=
C:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: identity file /.ssh/id_rsa type -1
...
ssh goes on to create /.ssh off of c:\cygwin and fails since no id_rsa files.

Copying .ssh/ into c:\cygwin results in this working.

Try:

c:\>set HOME=/home/tda
c:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: identity file /home/tda/.ssh/id_rsa type 1
...
(succeeds, but I need HOME to be "correct" for other apps)

Try returning to Windows default:

c:\>set HOME=c:\Users\tda.DCA
c:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
Could not create directory 'c/.ssh'.
debug1: identity file c/.ssh/id_rsa type -1

Sorry, I cannot reproduce this, even with all my Cygwin processes stopped prior to running this:

C:\>set HOME=c:\users\lhall

C:\>ssh -v ds9
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Reading configuration data /etc/ssh_config
debug1: Connecting to ds9 [192.168.1.190] port 22.
debug1: Connection established.
debug1: identity file /home/lhall/.ssh/id_rsa type 1
...
(succeeds)

But looking back at your '/etc/passwd' entry, you have:

tda:unused_by_nt/2000/xp:1000:513:U-laptop1\tda,S-1-5-21-2414507100-3802266639-3593817948-1000:/home/tda:/bin/bash

When I compare that to the home directory you want (HOME=c:\Users\tda.DCA),
I'm wondering if you have a mismatch of usernames.  What does 'id' tell
you your user is?

Also, I note that our debug output for 'ssh -v' differs.  You may want to
investigate that some too.

Other stray ideas which may or may not be relevant:
  BLODA
  Downgrade OpenSSH
