SSH access to desktop

SSH access to desktop

[Kevin Layer]

I need to be able to SSH into a Windows machine with Cygwin installed
and be able to run Windows programs and see the Windows they create.
That is, when I run "notepad" I need to see the Window it creates.
And, I need multiple users to be able to do this.

In the past, I did this by having each user put an item in their
Startup folder that did:

   C:\cygwin64\usr\sbin\sshd.exe -p 8100

where the port, 8100 in this case, is different for each user.

The snag now seems to be:

$ /usr/sbin/sshd.exe -p 8100
/var/empty must be owned by root and not group or world-writable.
$ ls -l /var
total 4
drwxr-xr-x+ 1 layer          Domain Users   0 Mar 16 10:13 cache/
drwxr-x--x+ 1 Administrator  Administrators 0 Mar 16 10:08 empty/
drwxr-xr-x+ 1 layer          Domain Users   0 Mar 16 10:06 lib/
drwxrwxrwt+ 1 Administrators Administrators 0 Mar 16 15:08 log/
drwxrwxrwt+ 1 Administrators Administrators 0 Mar 16 10:51 run/
drwxrwxrwt+ 1 layer          Domain Users   0 Apr  2 00:42 tmp/
$


The "in the past" is on an older version of Cygwin that hasn't been
updated in a while.  The new machine, where this is not working, is
pretty up to date.

Ideas?
Thanks.

Kevin

Try making the owner of this directory the same as the Windows user that is running the sshd service. I think this is a hard coded error message that says "root" in the expectation that this runs sshd. But that is not the case on Windows/Cygwin.

Here's what worked for me:

Ran ssh-host-config as administrator and took defaults, except
 priviledge separation => no
 install as a service => no

Then, I chown'd /var/empty to Administrator and was able to run
"sshd -p 8100" and ssh into the box.

More importantly, other users were able to start their own sshds, on
different ports, and also ssh into the box.
