This is version @(#)README	1.2 7/24/91 of the pcnfsd README file.
----------------------------------------------------------------------
This is the second cut at PCNFSD v2. All printing now uses the same
SVR4 based printing model: lp, lpstat, cancel. This implies SunOS 4.1
or later on a Sun. The printing hasn't been properly tested on SVR4,
since my SVR4 system is a bit quirky, but authentication via shadow
passwords works fine.

The Makefile supplied will build either SunOS 4.1 or SVR4 versions;
however you will need to tweak a couple of definitions. See the
Makefile for details.

For this round, I have frozen the rpcgen'd code and modified it by hand
to get around a few rpcgen deficiencies. If in doubt, you can take the
pcnfsd.x file included here off to a separate directory, rpcgen everything
up and diff against the versions given here.

You should also be sure to read the man page. I haven't tried [nt]roff'ing
this anywhere outside SunOS, so let me know if there are any quirks.
Note especially the /etc/pcnfsd.conf configuration model.

Standard disclaimers. Read the source for more of the same.

----------------------------------------------------------------------
This is the first major spin since the version I posted in May.
Changes are described in the SCCS deltas, but anyone analysing
or porting this should watch for the following:

- Lots of SVR4 stuff. Look at the Makefile and common.h; you will
  need to make sure that SVR4 is defined to build a version for SVR4.
- Fixed a major bug whereby aliased printers (a.k.a. virtual printers)
  didn't show up in the printer list.
- Since some commands (especially lpq) can hang up forever if, say,
  the host of a remote printer is down, the su_popen mechanism now
  includes a watchdog timer. I HAVE NOT HAD A CHANCE TO TEST THIS
  LOGIC ON SVR4 YET! The code was derived from the System V compatiility
  section of the AnswerBook, so it _should_ be OK, but I can't wait to
  test it before posting this.
- I've mades lots of lint-suggested improvements. It doesn't lint
  100% cleanly yet, but it's a lot better.
- The client testbed has been tightened up a bit and the reporting
  is somewhat clearer. Please run it.

Feedback is solicited.
