The program I intend to make will be developed as a service "pinging" on 
a regular basis remote stations just to see if they are alive. The way 
that Indy implements ICMP protocol means that "pinger" socket is 
available only under root permission. The same test programs which fails 
under normal user succeeds under root.
This is clearly stated in Indy FAQ. Read http://www.indyproject.org/KB/ 
for this subject and associated questions.
