(Funny how I so often get port 23 mixed up with 25, but never 25 confused with 23. A strange form of lysdexia I think.)
Anyway I think it will take me some time to fully understand all you've written. But one question to clarify. Are you saying that I can setup the telnet port (usually 23) to be a TSO connection and the rlogin port (usually 513) to connect to rlogind -- which seems to me to be the most usual setup -- OR I can use one port, say telnet 23, and take advantage of VIPA's such that I get to either TSO or rlogind via a (virtual) IP address? So in one case I change the port number, and in the other case I change the IP address? -Lindy -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Chris Mason Sent: Sunday, November 05, 2006 6:15 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: Java Error Chris said: Now we can be thankful for VIPAs which have the property not to tie an IP address to an interface but to tie an IP address to an IP node or, even better as in fact here, to tie an IP address to a particular application on an IP node. In fact, using VIPAs we no longer need a port number in order to locate a "server" application. This, however, is not possible because the underlying IP demultiplexing logic insists on processing a port number. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
