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
