cygwin:
I was attempting to update/upgrade my Cygwin installation:
1. Rename C:\cygwin to C:\cygwin-old
2. Create new folders C:\cygwin and C:\cygwin\setup .
3. Download latest Cygwin Setup and save as C:\cygwin\setup\setup.exe .
4. Run Cygwin Setup and download/ install base system from Internet.
5. Run Cygwin Setup and download/ install openssh from Internet.
6. Run Cygwin Bash and configure ssh:
Administrator AT a64x23800p ~
$ ssh-host-config
Generating /etc/ssh_host_key
Generating /etc/ssh_host_rsa_key
Generating /etc/ssh_host_dsa_key
Generating /etc/ssh_config file
Privilege separation is set to yes by default since OpenSSH 3.3.
However, this requires a non-privileged account called 'sshd'.
For more info on privilege separation read
/usr/share/doc/openssh/README.privsep
.
Should privilege separation be used? (yes/no) yes
Generating /etc/sshd_config file
Host configuration finished. Have fun!
$ ssh-user-config
WARNING: group and other have been revoked write permission to your home
directory /home/Administrator.

using
the key files stored in your .ssh subdirectory.
Revert this change ONLY if you know what you are doing!
Shall I create an SSH1 RSA identity file for you? (yes/no) no

Configuration finished. Have fun!
7. Run Cygwin Bash and attempt to start sshd:
$ net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
8. Look at /var/log/sshd.log:
/var/empty must be owned by root and not group or world-writable.
9. Adjust mode of /var/empty and attempt to start sshd:
20080217-144322 Administrator AT a64x23800p /var
$ ll -d empty/
drwxr-xr-x+ 2 Administrator None 0 Feb 17 14:30 empty//
20080217-144326 Administrator AT a64x23800p /var
$ chmod 700 empty
20080217-144400 Administrator AT a64x23800p /var
$ ll -d empty/
drwx------+ 2 Administrator None 0 Feb 17 14:30 empty//
20080217-144405 Administrator AT a64x23800p /var
$ net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534.
10. Look at /var/log/sshd.log:
/var/empty must be owned by root and not group or world-writable.
11. Change owner of /var/empty:
20080217-144416 Administrator AT a64x23800p /var
$ chown root empty/
chown: invalid user: `root'
12. STFW. root is not a valid user name. Make an educated guess and
try again:
20080217-151048 Administrator AT a64x23800p /var
$ chown SYSTEM empty
20080217-151056 Administrator AT a64x23800p /var
$ ll -d empty/
drwx------+ 2 SYSTEM None 0 Feb 17 14:30 empty//
20080217-151108 Administrator AT a64x23800p /var
$ net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service was started successfully.
Per http://www.cygwin.com/problems.html, cygcheck.out is attached.
I don't know how to put the above fixes (chmod, chown) into Cygwin;
perhaps the openssh maintainer can do so.
HTH,
David
