The LUNAME is a part of the tn3270E protocol, but I would hesitate to use it as a client identifier; it’s more about what on the server the client thinks it wants to access. You *may* configure the tn3270 server to use LUNAME to determine which USSTAB to use for the session or even to connect directly to a particular VTAM application. The OSA-ICC tn3270 server *requires* clients to provide an LUNAME, and uses it to select the LPAR and unit number for the session. Those are the two tn3270 servers I’m familiar with. Others may do other things with the tn3270 LUNAME. There’s no inherent security on LUNAME, though; all tn3270E clients I know of allow the user to put anything in there. It’s up to the server to decide what to do with it. -- Pew, Curtis G curtis....@austin.utexas.edu ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
