We have a network of macs and printers that number about ~3000 on kinetics fastpaths. With the Fastpaths in place, the ethernet is for all intensive purposes transparent, we have sites in Minneapolis that print out on printers in Duluth, and we have both Minneapolis and Duluth providing appleshare file service to clients on opposite campuses. It seems that the Cayman Gator box will do this and more, such as their version of TOPS - a sun NFS server for appletalk. We haven't gotten a copy, because of production backlog. For our UNIX hosts, we run Columbia Appletalk Protocol (CAP) software which will allow our unix hosts to be appleshare hosts - effectively another Large appletalk device. This has two beneficial side effects. We now run UNIX spooled printing on appletalk to postscript printers. We can now also dump our Mac harddrives to the UNIX hosts. This saves time on backups, and the aggravation of having to deal with hundreds of those little floppy discs. I hope this helps - I don't have any experience with the MIPS.xxx machines.

Thanks Because of the numbers of letters I have received regarding my previous response about CAP software, I am posting excerpts from the CAP release notes to the newsgroup. CAP is available under annonymous ftp from cucca.columbia.edu and is located in the ~ftp/cap directory under cap50.tar.Z. Tim Peiffer peiffer@umn-cs.cs.umn.edu or Comp Sci Dept ...!rutgers!umn-cs!peiffer Univ of Minnesota >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAP - Columbia AppleTalk Package for UNIX (4.2 BSD). (For use with AppleTalk/Ethernet bridge) This distribution should allow asp, atp, pap client and server applications to be developed. -- Portions are of the CAP distribution are public domain software. The specific item is: extras/att_getopt.c Portions of the CAP distribution are contributed by other sites including: Rob Chandhok, Computer Science Department, Carnegie Mellon University Paul Campbell ABSTRACT -------- CAP is written for BSD 4.2 Unix and derivatives. CAP implements a library containing a portion of Apple Computer's AppleTalk protocols. In order to use this package you need an AppleTalk/Ethernet bridge (e.g. Kinetics FastPath box). CAP includes a number of applications that can be used to print to a LaserWriter, spool for a LaserWriter, and act as Unix based AppleShare compatible file server (no support for AppleShare PC). CAP also includes a number of sample programs and contributed software. CAP library routines are structured, for the most part, the same as the Apple routines described in "Inside AppleTalk" and "Inside LaserWriter." Refer to the Apple documents and the procedure comments for a complete description of the routines and how to call them. Prerequisties ------------ o Kinetics FastPath box running the 10/86, 2/87, 9/87, or 1/88 Revision of the UDP software, known as "KIP", developed by Bill Croft at SUMEX, Stanford University is required. o baseline host system: Ultrix 2.0-1. Most will work under BSD 4.2, BSD 4.3, Ultrix 1.0-1.2, Sun OS 3.2 or higher, ACIS 4.2, A/UX, and other systems with BSD like networking facilities with varying levels of functionality. Under certain systems, only portions will work. Information ----------- There is no CAP mailing list. Instead, notices and information about CAP are posted to the mailing list info-appletalk which is gatewayed with the USENET news group comp.protocols.appletalk. If you don't have access to comp.protocols.appletalk and have access to the ARPANET, you can get on the mailing list by sending mail to info-appletalk-request#@andrew.cmu.edu. [The '#' part of the address is currently optional, but it helps speed up delivery.] Important documentation resides in: NOTES - installation notes: READ THIS BEFORE STARTING INSTALLATION PORTING - notes on porting CAP to machines it doesn't know about MANIFEST - a list of files that comprise CAP doc/installation.ms - stepwise installation document: assumes you have read NOTES and this document What's in CAP ------------- The Columbia AppleTalk Package consists of a number of libraries, a number of programs, and associated documentation. Following is a list of the main parts along with a brief description. o NOTES for a general overview of installation and some overview material. o PORTING for information about making CAP work on systems not listed in NOTES netat - general header files used by various parts of CAP man - man pages for some of the programs doc - documentation lib/cap - main appletalk libraries: ASP, PAP, ATP, NBP, DDP lib/afp - generic AppleTalk Filing Protocol (AFP) routines lib/afpc - AFP client libraries etc - support programs: only atis - support program for NBP extras - code and materials not necessarily related to AppleTalk samples - sample programs: allow simple interaction with lw, appleshare server, etc. See README there. contrib - contributed programs applications - main applications. The following programs in applications are in regular use at Columbia and are a main part of the reason we work on CAP: papif - UNIX lpd "input" filter for spooling to appletalk - also includes sample "output" filter and printcap entry - Note: this is a very bare bones filter lwsrv - Simple LaserWriter spooler suitable for extension aufs - AppleTalk Filing Protocol Unix File Server - Note: does NOT support AppleShare PC NOTE: You must have the AppleShare 1.0 or 1.1 client code installed in your Macintosh to use this. You must obtain this from Apple - we do not and do not plan to supply this. The client code is a lot of work and Apple's already done an excellent job here - well worth paying for.
