cygwin: can't get openssh working via inetd

[Brendan J Simon]

I can't get sshd workding via inetd.  I'm following the instructions in 
/usr/doc/Cygwin/openssh-2.5.1pw.README.
I it does work perfectly if I invoke sshd manually from the bash 
prompt.  This indicates to me that there is a problem with sshd running 
as SYSTEM and trying to fork and change users.  I see

[bjsimon@k9:~]$ ssh zigfried
bjsimon@zigfried.ctam.local's password:

Is this an NTSEC problem ??  I'm running Windows 2000.
My /etc/ssh_config has everything commented out so it should have the 
defaults.
   PasswordAuthentication yes
   RSAAuthentication yes

There is mention in the docs that when using ntea or ntsec you now have 
to care for the ownership and permissions bits of your host key files 
and your private key files.  I have tried changing the permissions and 
ownership with chmod but nothing happens !!!  ie. chmod and chown don't 
seem to have any affect.  I created a file in /tmp and tried to change 
its owner to SYSTEM but ls -l reveals nothing changed.  The same when 
trying chmod +w /tmp/file.

Why can't I change permissions and would this be the reason sshd running 
as LocalSystem doesnot operate properly.

Thanks,
Brendan Simon.

You can't. When using sshd under inetd (WHICH IS NOT RECOMMENDED)
sshd starts up under the same user account as inetd, typically
the "LocalSystem" account. This LocalSystem account doesn't have
access to network drives. Even if that would be possible you
would have to give your password to be able to change the user
context.

I suggest starting sshd under your own account. Don't use inetd
for that. Read /usr/doc/openssh-2.5.2p2.README

Thanks Karl,

The new cygwin1.dll fixed the ssh problem I was seeing.  I can now login 
in successfully but I have to enter my password everytime.  Obviously 
the sshd is not looking into my home directory (which is on a mapped 
network drive) for my .ssh/ directory.  How do I get around this ???

Thanks,
Brendan Simon.

Hi Brendan...

I had the same problem. I downloaded the 20010325 snapshot of the 
cygwin1.dll file and that took care of it. The issue shows up when the 
user-id of the sshd is different than the user-id of the client.
