>Description:

We shouldn't ever allow mode 6 or 7 commands to modify the NTP config;  this
should be done via the CLI only, as it is Yet Another Security Hole and
the changes will be lost anyhow when xntpd restarts.

>How-To-Repeat:

	

>Fix:
	
Don't allow request-key or control-key to be configured (remove from the DDL).
Ensure that destructive request and control packets are not allowed if the
local key is zero (I don't believe this is true for control packets;  xntpdc
won't send a packet with a nonzero key, but I think xntpd will accept
them).
