RE: Ports used by home-grown applications

What are the ports that we can *safely* used on the firewall 
by home-grown
application programs?  Any suggestions/pointers are appreciated.


What does your question mean?  Any port can be safely
used by any application, assuming the application is
written securely and the port isn't already in use.
Of course, to open a port < 1024 you need root
privileges, so maybe that answers your question?
If a port < 1024 needs to be used (why, if it's a 
home-grown app??), the program can drop privileges
after the port is open.


Hope this helps,

~Patrick
