Passworld console commands

I made a 12 slot bukkit server for my son who is 10. The server has bin up and runnig for a few months.
The problem I'm having is that my son op's players form the console then those players op there friends
untill the server is greifed or crashed using worldedit. I'm using Remote tool kit plugin for the wrapper. The stop command only restarts the server. If an op'ed player types /stop the server will just restart . The Wrapper command /stopwrapper needs a password to shut the server down. Is there a way to block or password op commands at the console?

Thanks

just quit the console

 

There are a couple plugins that 'verify' ops; have a search around BukkitDev if this doesn't appeal.

 

get a permissions plugin like group manger. link:http://cloud.github.com/downloads/essentials/Essentials/Essentials-gm-2.9.4.zip

 

Using Groupmanger, Essentials,Worldguard, Worldedit.... Thats Not the problem. My son as access to the server computer. Quit the console? Doesn't that shutdown the server? I can minimize the console window but my sons not stupid. I install the opverify bukkit plugin and with that you need a password at the console to add a player to op. I will look at other one to see the diffrence. This is what I was looking for.
