I suggest that you start a new thread. The issue you are facing is 
different than the topic of this thread.  Thanks.

Re: Windows 7 Agents (slaves) via SSH

I launch my Windows agent on Azure using install agent as windows service 
and running that. But the service keeps restarting very frequently causing 
the build to break when it is triggered at this time. Can you help me?

I launch *Windows agents* from the Windows Desktop (calling them JNLP in
that case seems like a misnomer).  They are not using "Java Web Start" to
launch.  They are launched from a batch file.

Re: Windows 7 Agents (slaves) via SSH

I launch my Windows 10 ssh agents using the instructions from the
ssh-slaves plugin page:

https://github.com/jenkinsci/ssh-slaves-plugin/blob/master/doc/CONFIGURE.md#launch-windows-slaves-using-microsoft-openssh

They use the Microsoft OpenSSH server on Windows 10.

I launch JNLP Windows agents with the following batch script:

Re: Windows 7 Agents (slaves) via SSH

[Slide]

The Chocolatey package for OpenSSH says that it should work on Windows 7
64-bit. I may have missed an earlier email, are your systems 32 or 64-bit
systems?

So, what does the master think the launch method is for the slave?

I have a batch file on the Desktop of the computer with a link to that
Desktop batch file in the Startup folder for the specific user.  The
specific user is configured to auto-login.  Thus, those machines run the
agent automatically when they boot.

Running from a running Desktop account also assures that desktop access is
available (for things like Selenium tests).

Re: Windows 7 Agents (slaves) via SSH

[Steve K]

Thanks Mark,
Web articles, such as this "Installing OpenSSH on Windows 7 
" gave me hope of 
finding a workable solution.
I had also considered trying to use Cygwin, as described by Kohsuke 
Kawaguci in the Wiki page "SSH slaves and Cygwin 
", but that 
seemed like too much overhead when several slaves/agents need to be 
configured.

Launching an agent with a batch file seems like a good alternative. Have 
you been able to auto-start such a script (for example, to run at boot 
time)?

Thanks again.

I would not expect OpenSSH server to ever work with Windows 7.  It doesn't
work with the original releases of Windows 10.  Microsoft didn't make
OpenSSH server available until a relatively recent Windows 10 service
pack.  It has been working quite well for me from the Windows 10 service
pack on the 3 or 4 Windows 10 machines that I run.

Since you were using JNLP from a web browser previously, I assume that
means you were launching from a desktop login.  If you're launching from a
desktop login, then you can launch the agent with a batch file instead of
using JNLP.  That works with Java 11.

Don't forget that the Java version running the agent process must be the
same major Java version as the Java version running the master.  If you're
running Java 11 on your master, you need to run Java 11 on the agent.  If
you're running Java 8 on the master, you need to run Java 8 on the agents.
