Open SSHD

Open SSHD

[Bret Jordan]

First off in answer to someone's question yesterday here is how I have 
gotten opensshd to work on NT, note I am still having problems with one 
aspect of it but I will explain that later on.

Here is my step by step


copied sshd.exe		to 	c:\local\sbin\sshd\sshd.exe
copied ssh-keygen.exe	to	c:\local\sbin\sshd\ssh-keygen.exe

give current user "Act as OS and the other special rights"

run	c:\local\sbin\sshd\ssh-keygen -d -b 1024 -f c:\etc\sshd_host_dsa_key

NOTE: I was unalble to get it to work with a passphrase other than 
<NULL>.  I will keep working on this, or maybe someone knows how to make 
this part work.

Then I put my config file at c:\etc\sshd.conf
And passwd file at c:\etc\passwd


Then run 	c:\local\sbin\sshd\sshd -d -f \etc\sshd.conf

and it works.
All I have in my config file right now is the following (I am still working 
over some problems):

Port 			22
ListenAddress 	x.x.x.x
HostDSAKey		/etc/sshd_host_dsa_key
KeepAlive		no

The passwd file looks like
someusername::1:10:User Name:/home/someusername:/winnt/system32/cmd.exe

NOTE: You can use base.exe in place of cmd.exe example:
someusername::1:10:User Name:/home/someusername:/bin/bash.exe

NOTE: You will need to modify some aspects when you want to run it as a 
service.

Does this help?


Problem:
---------------
I can make a connection to a nt box running opensshd.  I can run most all 
dos/nt commands.  I can even run most all of the bin utils.  The problem 
come around when I try to run a program that is a command character program 
(edit, vi, emacs -nw, pmon, etc).  When I try to run these programs it just 
causes the connection to hang.  When you run vi it causes the connection to 
lock up and on the box running sshd the window in which sshd was started 
now looks like the VI window.  However, it is frozen as well and will not 
allow any input.  You have to kill the vi process which then kills the ssh 
connection.

Question:
Can you, and if so, how do you run command character programs through the 
ssh connection?  Is there some sort of ENV variable I need to set?

Thanks

Bret

Along those lines, I wrote up a web page with my steps to getting it work:

Hope that helps someone.

Please note that OpenSSH and OpenSSL packages are officially part of the
base distro since 26-9-2000, announced on 27-9-2000:

http://sources.redhat.com/ml/cygwin/2000-09/msg00915.html

The Cygwin setup did downloaded them since that date as well.

I don't understand the problem here. I have described the installation
in detail in the README file `/usr/doc/Cygwin/openssh-2.2.0p1.README'.

For the beginning it will be helpful to start the script
`/usr/bin/ssh-config' which creates the necessary configuration and
key files.

Both files were already part of the original distribution on
ftp.franken.de and their existence was announced more than once in
this forum.

Don't use Windows paths. Your description is ok if the installation
root is C:\ but this is not the default installation. Your description
would be valid in all environments when using POSIX paths like

  copied ssh-keygen.exe to /local/sbin/sshd

This is correct behaviour.
As it's even mentioned in the ssh-keygen man pages the host key must
have an empty passphrase.

Where did you get the uid/gid? They are not related to the id's which
are given by NT. So you didn't use mkpasswd/mkgroup for creating your
/etc/passwd and /etc/group files. It's called by the Cygwin setup in
the postinstall. If you didn't use setup.exe, call them by yourself.

I already answered your question yesterday:

Yes, but it still does not fix the problem.
