RE: Ports used by home-grown applications

[GibsonB () gruntal com]

What do you mean by safely?  So as not to conflict with existing
applications or ports that are less likely to allow breaches into the
machine or network?

If it's the former, there is an RFC that list all the well known ports.
There are LOT of services so perhaps you might want to think about what
services you might want to use and avoid their ports.  

If it's the latter then you should use unprivileged ports(ports over 1024).

The bigger question is why would you want to run applications on your
firewall?  This is a VERY BAD IDEA.

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

Thanks,

Ivan
