Best would be a system call, but I can also live with some functionality that parses the etc/services in Linux/Windows directly. For support in the Java runtime I only found a 15 year old enhancement request in Oracles Bugzilla ... :-/ - Jörg - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org

Sounds like a suitable enhancement for Commons NET? - Jörg - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org

This is useless, you will need the current settings of the system. It is not uncommon in large companies to modify the official mappings, remove unwanted or add private ones. - Jörg - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
