Between servers that you control you had build ntpd to use any port you like. But of course to comunicate with servers outside your control you have touse the agreed to port. At soe point to will need a ntpd server tat faces both ways to "pool" servers on the Internet on port 123 and to your internal servers. This server will need to listen on bth 123 and your custom port number. Now the question is "Why?" what is the reason for not using 123? Broadcast might solve this problem. If you can use broadcast then you are not using 123. But again what is the big picture, what is the problem to be solved by all o this? -- ===== Chris Albertson Redondo Beach, California _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
