A while back someone asked for suggestions for printing in a heterogeneous environmment. Several Unix and VMS type machines. I haven't seen the summery posted so if some one has a summery please email it to me. I am intrested in the VMS TCP/IP solutions. Thanks Brian Ridout ridout@ddnvx1.afwl.af.mil

I've been busy for several weeks moving offices, and haven't quite regrouped yet. I received several suggestions in response to my query: (1) lpr, supported natively under UNIX, and by various third party TCP/IP solutions for VMS and MVS (assuming one has a front end processor for the IBM system, of course). Not all fep's support lpr, and some only unidirectionally (into the IBM, usually spooled into a JES queue). (2) Project Athena's Palladium distributed print spooling system. This appears to be quite a sophisticated and viable solution, if one can afford to go strictly TCP/IP. It operates under a client-server model, much like lpr, but the similarities stop there. It uses Hesiod for name services, Kerberos for authentication services, and Zephyr for notification services. To my knowledge, neither the client nor server software has been ported to VMS or other non-UNIX platforms. For more information on Palladium, reference the Usenix Conference Proceedings, Winter 1988 (Dallas). I also have an 8 or 10 page document (Postscript format), compliments of a friend at MIT and published by several DEC and OSF employees, which describes Palladium. If anyone is interested, please request via email to me, not by posting. (3) NJE, which is native to the IBM world, is supported under VMS by JNET, and under UNIX by UREP (UNIX RSCS Emulation Program). (4) The University of Illinois has a home-grown distributed printing system, which appears very well architected. Like Palladium, it is TCP/IP-based, runs under UNIX, and it interfaces with lpr. It also has an accounting component. (5) Delft University of Technology (Delft, Holland) also has developed a TCP/IP-based lpr-like system, with enhancements for accounting, filtering, and more. I have contacts at Illinois and Delft, but am unwilling to broadcast names or detailed information without permission. Contact me via email if you're interested. I think this sums it up, for the most part. Thanks for prompting me to share this information. //=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=\\ || Larry J.
