I am developing a FTP-server in Java. When I try to start ot as a normal

only on one port)?



Normal users are not allowed to open ports below 1024, only root can. FTP is 21 and 20.


Ports over 1024 work as a beginning. Altough that is a bit difficult bcause I have to type "127.0.0.1:1025" everywhere. I rephrase my question: Is there a way (expect from suid) to allow normal users to run a server that listens on port 21?
