Event handlers for handling Windows services

[Erik N. Mullinix]

This is an interesting concept Andy.
The ability to handle common failures within a service or system is
valuable to larger scale networks.
You can however within an active directory dc network use command line
on a remote system to start services such as IIS.  Take a look at the
Windows 2000 Active Directory Black Book by Adam Wood with Coriolis
Press (ISBN 1-57610-256-4).  This might give you the method you're
searching for without exposing your environment to the evils of security
failure and reduce the load or need of using FTP or allowing FTP access
to and from windows servers.  You will also get a lot more out of your
Nagios machine if you do not run FTP sessions.

I have another idea.  Probably exposes some security risks.....but
that's another discussion.

Have your service check on Nagios pipe some arguments out to a file and
then ftp them to a windows server.  From there, have a task scheduler
job run on windows with enough permissions to be able to use the params
in the ftp'd file to act on it.

I have been thinking about this and thought about this scenario.

Nagios checks a web server
Web server fails
Nagios executes a script that has $HOSTNAME$ $SERVICEDESC$
$SERVICESTATE$ $SERVICEATTEMPT$
In the script, it eventually runs it and all of the checks line up and
then the script would create a small text file with the hostname and the
service - probably a good idea to adjust this to be the actual line that
would start / stop the service (eg: netsvc IISADMIN \\hostname /stop)
Then have a script on the ftp server that is able to run that script.

Again, this leave open all kinds of holes for someone to arbitrarily
start and stop services....but you could throw in some text to act like
a password and also restrict ftp from certain hosts.  My intent is only
to show a way to pull this off.

The question can be answered if you can answer the question, "Can you
start/stop Windows services from the command line?"  I think.

If you install Cygwin, you have the option of turning on an SSH daemon
service.  Once you get the proper authentication set up (most likely
using a
null passphrase), so long as you can access the start/stop command from
within the Cygwin environment (might require copying/linking the
authroitative Windows command), then I don't see why not.

If you try this approach, let us know how it works out.
