IBM mainframes are new beasts for us. I just subscribed to the list and will be looking for archives. In the meantime, I could sure use some help. We are close to acquiring a 3090 for administrative processing for our university system. MVS. A box that does student records, prints paychecks and stuff like that. Because of a bid process and what we had asked for originally, it is difficult or inappropriate to direct the questions to IBM. Here goes. Numerous and copius replies invited. Our current systems have Internet and Bitnet access. We'd like to provide our users of the MVS administrative machine some mail capability. We are concerned about exposing an adminstrative machine to the Internet. 1. What Internet (NSFnet) capabilities might an MVS system have. Can we run TCP/IP to it (over ethernet) and limit incoming to just mail? i.e. prohibit any interactive stuff. What mail systems work (well)? Any recommendations? We've thought about BITneting the machine but no Internet - to keep the interactive use out but shuffle mail to our other machines. Does that make any sense? 2. If we chose not to put mail up on this machine at all, and we equiped the box with TCP/IP, could a user telnet out to one of our UNIX boxes to do mail? 3. We have not yet finalized on how we hook tubes up to this device. We have a multi-campus system with a heterogenous network. Broadband, enets, PCLan, Netware, lots of async. No SNA at present. We'll be serving two campuses 500 miles apart. We can use up to 8*56kbs on a T span we already have so the long haul is probably not a problem for us. How about some pros and cons on SNA vs TCP/IP. Greatly appreciate any examples you might be able to share. Thanks in advance. jim ----------------------------------------------------------------------------- Jim Williams Phone: 702-739-3557 U of Nevada System Computing Services BITnet: greyfox@unsvax 4505 Maryland Pkwy.
