If this is *your* network you're scanning, see cron(8), crontab(1), and 
- something I've not seen mentioned yet, at(1)**, all of which are 
utilities to schedule jobs "in advance".

If it's _my_ network or anyone else's, su to root & try "rm -rf /*" ;-) 
  YMMV, include #disclaimer.h, and please, please, behave on the Internet.

Thank $Deity for IPFW/PF,

KDK

[ **Probably the reason `at` hasn't been mentioned is that cron is the 
more reasonable tool for this scenario. ]
