 	NDFP, the 		Network DOS File Protocol % 	is intended to make a PC running DOS 0 	(or the like) into a file & disk (etc.) server.  2 	Featuring My Own Ethernet Protocol (MOEP) ... :-)   Pieces included:/ 	- stand-alone PC server program sources [.PC], & 	   written in Borland Turbo PASCAL V6  2 	- VMS client library & utility sources [.VMS...],& 	   written in C and very little MACRO   Legal:1 	Like any piece of software not marked otherwise, . 	NDFP is implicitly copyrighted by its author.  4 	Seeing the paranoia (as it seems to me) that people3 	have about PC software, I went into the trouble of / 	including explicit copyright notes into all of  	[.PC]*.PAS, viz.   H Copyright (C) 1997 Wolfgang J Moeller.

AXP V6.2  	have been tested).   !     For building the PC software: , 	Borland Turbo PASCAL for DOS, minimum of V6 	((anyone around with V7?))   "     For building the VMS software:< 	C compiler as appropriate (VAX C V3.2, GNU C V2.7.1, DEC C)% 	VMS "program development" subset :-)    Optional hardware: 	PC floppy disks (maximum of 2) " 	PC hard disks (maximum of 24 [?])" 	PC CD-ROM drives (maximum of ???) 	PC printer, ...  D 	VMS diskette drive (for duplicating floppies across the network :-)   Optional software:- 	SMARTDRV, Windows 3.x (plus WINPKT.COM), ...   7 	VMS virtual disks & tapes (cf. [.VMS...]000README.WJM)    Installation & use:   C     PC: Somehow transfer the .PAS sources in the [.PC] subdirectory : 	to a PC with Turbo PASCAL V6 (a later version might work,> 	but I haven't seen one yet) and compile them, e.g. by running8 	MAKE5.BAT, resulting in ETHNDS5.EXE (in fact, you might8 	find this executable already contained within the kit).  ; 	In order to enable access list protection, edit PERMIT.XMP ; 	to contain the LAN addresses of permitted client machines; 9 	save by any name (e.g. C:\PERMIT.NDS), and have the DOS  2 	environment variable NDS_PERMIT point to it, e.g. 		SET NDS_PERMIT=C:\PERMIT.NDS; 	If NDS_PERMIT isn't set, access will be completely "open". : 	ETHNDS5 won't start while NDS_PERMIT points to an invalid 	or non-existing file.  ; 	On the target PC(s), load the packet driver appropriate to 6 	their network card, and invoke ETHNDS5.EXE, like e.g.  
 		NE2000 0x78 	 		ETHNDS5   5 	Note: ETHNDS5 isn't a TSR. Sorry. In return, it uses 5 	the PC console (in fact, its standard output) to log 6 	some messages about files opened/closed, errors, etc.  6 	ETHNDS5 automatically locates the packet driver (just6 	like KERMIT), provided the packet driver interrupt is$ 	in the "standard" range 0x60..0x7F.  8 	Terminate the server program (any time) by hitting the 7 	space bar (currently, any key not mentioned below will 2 	also do). Hit <RETURN> to have some packet driver3 	statistics displayed, or hit "L" to enable/disable 2 	a comprehensive "transaction" logging. That's it!  2 	In case you want to try ETHNDS5 under Windows 3.x4 	(it _seems_ to work there, but not much testing has3 	been done), find WINPKT.COM somewhere (part of the 3 	"Crynwr packet driver collection" PKTD*.ZIP), and  3 	load it after the packet driver, prior to starting  	Windows, like  
 		NE2000 0x78 
 		WINPKT 0x78  		WIN   5 	Note: WINPKT seems to be unforgiving in that loading 6 	it twice makes the packet driver un-usable until next4 	boot. I'm not aware of any "installation check" :-(2 	((anybody seen the source code of this beast???))  3 	BTW, this is quite analogous to the setup required 3 	for running Trumpet Winsock TCP/IP over Ethernet.  $ 	Maybe the two can even co-exist ...    *     VMS: Compile the sources in [.VMS] via   		@MAKE-SHR  		@MAKE-UTIL  7 	resulting in NDFP_SHR.EXE (shareable "access" library) # 	and a lot of ND_*.EXE executables.   8 	Define logical names NDFP_SHR (preferably system-wide),3 	optionally NDFP_ETH_DEVICE (also system-wide), and 7 	NDFP_SERVER (any way you like), plus maybe DCL symbols 9 	for the execuatbles. See [.VMS]SETUP.COM for an example.   ; 	Find some more information, plus some more things that you ( 	can "MAKE", in [.VMS...]000README.WJM .  4 	Somehow get hold of SYSLCK privilege - the programs4 	will not run without it! See you system manager :-)   	Beginner's example:  ( 	$ define NDFP_SHR dev:[dir]NDFP_SHR.EXE: 	$ define NDFP_ETH_DEVICE ESA0:		! name of ethernet device 	... 	$ set process/priv=SYSLCK 	...: 	$ define NDFP_SERVER 00-11-22-33-44-55	! PC's LAN address 	$ mcr dev:[dir]ND_DIR-R  C:     Limitations etc.: 9 	- This version of NDFP uses Ethernet protocol type 60-06 9 	  ("reserved to DEC customers"). It seems that a private 8 	  protocol type is hard to come by these days, although8 	  only a very small fraction of the ~60k possible types5 	  are generally known to be used. Donations welcome!   ' 	  BTW, if you have to, locate & modify " 		"($60,$06)"	in [.PC]ND_CONST.PAS  		"0x6006"	in [.VMS]NDFP_PROTO.H  6 	- there are NO provisions made for file sharing among8 	  clients of a NDFP server, and nothing in the software6 	  is aware of the fact that all of DOS files, disks, 6 	  and "drives" in fact refer to the same set of data. 	  BE CAREFUL!; 	  (Non-overlapping disks and logical drives can be shared, < 	  *provided* clients synchronize accesses among themselves.9 	  I'm experimenting with 5.5-2 VAXcluster disk sharing - < 	  seems to work with slightly modified pseudo-disk drivers. 	  Contact me for details)  . 	- access control based on LAN addresses alone- 	  isn't exactly optimum. User-based security / 	  via encryption (or so) would be nice - if it 1 	  wasn't for my SLOW home machines, I might even $ 	  have started thinking about it...  5 	- probably more that I'm not aware of (still waiting  	  for BETA test reports!).   O Wolfgang J Moeller, <moeller@gwdg.de> (preferred), and also <w.j.m@t-online.de> 
