Gotta ask - why aren't you going directly to the TN3270E server in z/OS Comm. Server? Seems like you're adding a Linux layer you don't really need.

Private GLANs/VSWITCHes work just fine, and it doesn't cost you anything.

If you are using layer 2 GLANs, the default MAC assignment will work, but you should assign a fixed address to the interface for stability reasons (and the fact that VTAM is such a PITA about MAC addresses). Also make sure that your MACPREFIX is set in the SYSTEM CONFIG. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
