Hi,


I'm trying to setup a cvs server on cygwin over ssh.

I have cygwin v1.3.22.1 installed on a win2k box.
I also installed the latest version of openSSH, and all related packages.

I also learned that one need to create a windows account for each user
willing to connect to the server.

In order to do some testing i just created 2 accounts on the windows
machine,say USER1 and USER2.

To enable connections through ssh one need to correctly setup 'sshd'. For that
USER1 ran 'ssh-host-config', since /etc/ssh_host_* files must be
read/write-able by only one account. Normally that user should have been
'root'. Browsing the web, i saw that it was not that simple
on cygwin (Please correct me if i am wrong).

Files
/etc/ssh_host_key,
/etc/ssh_host_rsa_key,
/etc/ssh_host_dsa_key

should not be group and world-accessible.

I then launched the following two commands
$ mkpasswd -l > /etc/passwd
$ mkgroup -l > /etc/group

Their content looks OK.

I then gathered USER1 and USER2 ssh2-rsa publickeys and put them in
their respective $HOME/.ssh/authorized_keys2 (on the server machine).

The windows machine was then booted on USER1 account in order to be able
to start 'sshd' by means of '/etc/rc.d/init.d/sshd start'

Connecting remotely to USER1 account by the following command worked just fine
$ ssh -v USER1 AT server_ip_address

But trying to do the same for USER2 by using
$ ssh -v USER2 AT ser_ip_address
just failed, since i am asked to provide a password.
The above command output showed me that the ssh2-rsa publickey auth just
failed.


QUESTION:
- Is the above configuration feasible ?
  assuming USER1 is a poweruser,
  USER2, USER3, ..., USERN are simple user.
  
- Does cygwin/cvs works fine in server mode using 'ext' protocol (ssh) ?
- Security-wise is (cygwin/cvs server / ssh) a good choice ?


Thank You In Advance for your feedback and or help. :-)
regards,
-Richard
