Cannot log in to SSHD, either with public key or password

Cannot log in to SSHD, either with public key or password

[Chloe]

Please help, I cannot log into Cygwin with SSH.

ssh -vvv Chloe@localhost log: http://pastebin.com/vt2aP86F

I don't know why it says
debug3: Could not load "/home/Chloe/.ssh/id_rsa" as a RSA1 public key
because I can use that key to log into a VPS.

I installed the latest ssh. I verified permissions:

---------------------------
$ ls -ld . *
drw-------+ 1 Chloe None     0 May 21 19:31 .
-rw-------  1 Chloe None   395 May 21 19:31 authorized_keys

-rw-------  1 Chloe None   640 Apr  6  2009 identity.pub
-rw-------  1 Chloe None 12226 May 21 19:30 known_hosts
------------------------------

This is the error in Application event viewer log:

---------------------
The description for Event ID 0 from source sshd cannot be found. Either 
the component that raises this event is not installed on your local 
computer or the installation is corrupted. You can install or repair the 
component on the local computer.

If the event originated on another computer, the display information had 
to be saved with the event.

The following information was included with the event:

sshd: PID 6840: Failed password for Chloe from 127.0.0.1 port 49802 ssh2
-----------------------

I've also tried
$ ssh chloe@localhost
and
$ ssh Chloe@127.0.0.1
and I've also tried Putty.

Here are non-comments in sshd_config

-----------------------------------------------------------
$ grep -v ^\# /etc/sshd_config | grep -ve '^\s*$'
Port 22
ListenAddress 127.0.0.1
StrictModes no
AuthorizedKeysFile      .ssh/authorized_keys
UsePrivilegeSeparation sandbox          # Default for new installations.
Subsystem       sftp    /usr/sbin/sftp-server
-------------------------------------------------------------

I see this in the sshd.log

----------------------------------
$ tail -1 /var/log/sshd.log
Could not load host key: /etc/ssh_host_ecdsa_key
-----------------------------------

But I don't understand why it can't open it. That's how ssh-host-config 
set it up. I had to change owner for sshd_config to myself so I could 
save my edits (ListenAddress).

------------------------------------
$ ls -l ssh*

-rw-------+ 1 Chloe      root 3640 May 21 20:10 sshd_config
------------------------------------

I checked in Task Manager and sshd is running as cyg_server.

Re: Cannot log in to SSHD, either with public key or password

[Evan Rowley]

This page has a lot of good information in it:
http://cygwin.com/cygwin-ug-net/ntsec.html

One part you might want to look at is where it mentions
"cyglsa-config" - this could be useful to you given what you're trying
to set up. In order to utilize this, you'll also want to enable the
"Create a token object" and "Act as part of the operating system"
local security policy options.

These are things I've missed in the past when setting up sshd to work
with key-based authentication. They might not be relevant to the
problem you're having, but it's still good to have the bases covered.

Fwd: Cannot log in to SSHD, either with public key or password

[Chloe]

I had to use 'mkpasswd -l' to re-generate my passwd file, (and also 
mkgroup), and re-ran ssh-host-config. Actually I tried 'su - Chloe', saw 
an error, tried to edit passwd manually, screwed it up and deleted 
'sshd' user (even though I don't see that user in Windows user 
management), found 'mkpasswd', restarted server, was trying to read 
another home directory, logged out of bash, log back in, re-ran 
ssh-host-config, and then it seemed to work.
