I hesitate a little to possibly just add to the noise because I don't really know the answer; I'm just hypothecating.
Does a workstation necessarily have a name? In the protocol, I mean. A dumb terminal with no name can do telnet. Is there anything to the connection request other than "Hi, I'm 192.168.1.1, let's connect"? There's no query where the mainframe says "tell me about yourself," right? I don't recall anything in my 3270 emulator (Tom Brennan's Vista) where I say "here is my name to give to the host." There is a space for an "LU name" but it's blank and I have no idea what it is for. My Windows has a hostname but there is no reason to think it is unique in any given host's clients. I fear the question may not have an answer. There's always my favorite approach: disable it and see who screams. (Yeah, you could put out some sort of warning broadcast a month in advance.)

The list of ip addresses needs to be translated to a workstation name because the ip addresses are volitile. Ping -a does not work on the mainframe. We want the command to be run from the mainframe. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
