That's actually what portmap is for. It maps a program and version number into a TCP or UDP port. The story is that Sun intented to register a bunch of dedicated IP ports when they were implementing NFS, but they haven't been allowed. So they've been using just one registered port (111 on TCP and UDP for the portmapper itself), and invented a more flexible scenario. -- J"org Wunsch Unix support engineer joerg_wunsch@interface-business.de [private: http://www.sax.de/~joerg/]
