Option 1: You could change the allowed admin user callsign to some  
obscure callsign and use that callsign if you have to command from on- 
air, but as soon as you do -- the bad guy will have it, if they're  
smarter than dirt.

Option 2: This is the reason why trying to limit Dplus control to  
certain users is fruitless.  It takes anyone about 10 seconds to copy  
a callsign and use it.  Might as well just open it up to all users and  
forget about trying to secure something in-securable.

Option 3: Do all commanding of links from SSH and forget about on-air  
control altogether, if you're insistent that only a certain sub-set of  
the repeater's users can make/break links.

Option 4: Turn off Dplus linking for a few days -- the person messing  
with it will be frustrated and try harder.  DF them and beat them with  
a stick.  ;-)

It's for the DV-Dongle.  Nothing to do with on-air commanding.
