My cygwin runs on a Windows 7. My problem is similar to a previous one

* /Subject/: Re: Strange behaviour of Openssh
however it's really different. My problem occurs earlier in the process.
I try to log in with ssh passwordless into a server that I've set up.
sshd is running there. I can log in with password.
When I set up the crypto (ssh-keygen -t ecdsa) and install the pub key
at the host, I can't login anymore, not by defaulting to password either.
What can cause communication to stop at this point:
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
Connection closed by 999.999.999.999
i.e. pubkey does not arrive at the client, abort.
You can see the whole monty at froste.oso.chalmers.se/hgs/cygwin
the ssh -vvv debug and the server's sshd_config Tell me if you need to
see more.
On two other pairs of machines, however, it's working according to the
book. I cannot see the difference.
Causes I can exclude:
sshd_config requests Protocol 2
* My key pairs are in /home/user/.ssh with the privileges set as needed.
* The pub key has been cat >> server:/home/user/.ssh/authorized_keys,
privil: -rw-r--r-
* The log shows that id_ecdsa is detected and okayed.
* I have renewed .ssh/knwon_hosts
* My /var/empty is not writable except for root.
Does the pubkey sending go through a different port, not 22?
Is there a timeout ?
These are the catalogs involved that are reported in the debug log
On the host side:
ls -l .ssh/
total 29
drwx------+ 1 Hans Georg Scherneck Ingen 0 2012-01-20 12:05 .
drwx------+ 1 Hans Georg Scherneck Ingen 0 2012-01-20 12:00 ..
-rw-r--r-- 1 Hans Georg Scherneck Ingen 175 2012-01-19 20:52
authorized_keys
-rw------- 1 Hans Georg Scherneck Ingen 227 2012-01-20 12:00 id_ecdsa
-rw-r--r-- 1 Hans Georg Scherneck Ingen 186 2012-01-20 12:00 id_ecdsa.pub
-rw-r--r-- 1 Hans Georg Scherneck Ingen 1963 2012-01-20 12:04 known_hosts
(when this machine acts as a server, I can login with key exchange
instead of password. Both machines' /etc/ssh_config are exactly equal
and use default settings only)
On the server side:
ls -la .ssh
drwx------+ 1 HGS None 0 Jan 20 12:01 .
drwx------+ 1 HGS None 0 Jan 20 15:36 ..
-rw-r--r-- 1 HGS None 361 Jan 20 12:02 authorized_keys
-rw-r--r-- 1 HGS None 1009 Jan 20 15:37 known_hosts
