This distribution contains a port of PPP-2.2 for NeXT. The full
source code is available as well as an MAB installer package. Since
this project is a continuing effort, you are encouraged to check out
the WWW page to see if you have the latest software. This is
especially true if you find you have problems with the version you
presently use. For more information on the NeXT PPP port see:

New to release 0.4.6 (LKS version 4.14)
=======================================
* Added a kernel optimization that will reduce the
interrupt load on the CPU. This optimization will
only work if you use the latest serial drivers supplied
by NeXT. You can get these drivers off of NeXTAnswers.
The optimization will not work if you use the Mux serial
driver. I believe that this optimization will solve many
of the kernel panics that people have reported.
* Added support for Microsoft's extended DNS negotiation.
This will only be of use for people who server PPP clients
using Win95, TechSmith Corporation's Foray PPP client
(http://www.techsmith.com) for WFWG 3.11, or others whose
client supports this mechanism. Thanks to
clameter@hur.fuller.edu (Christoph Lameter) for supplying the
patches. This patch is totally untested since I don't serve
any clients, and if I did I wouldn't admit to running a
MicroSloth operating system.
* Various minor fixes to documentation and examples.
New to release 0.4.5 (LKS version 4.9 release1)
======================================
* This release is based on the third beta release of
PPP-2.2 (ppp-2.2b3.tar.gz) by Paul Mackerras. It will
probably be the version released along with PPP-2.2.
* Some enhancements to the Example ip-up and ip-down
scripts.
* Several documentation enhancements to support the
actual release.
* Removed the new locking code. Temporarily, we continue
to rely on the old mechanism.
* This program runs on Intel, Moto, and Sparc. It apparently
runs fine on HP until shutdown. Then there appear to be problems.
Due to time constraints, this will have to be corrected as a patch.
As usual, this will be available on ftp.thoughtport.com:/pub/next/ppp/.
New to release 0.4.4 (LKS version 4.5)
======================================
* The netbuf queueing mechanism was significantly
simplified. It is hoped that some HP memory
alignment problems were also solved. This may
help solve some of the mysterious panics others have
seen.
* A new locking mechanism was implemented that
may simplify the spl() calls.
* Memory allocation in BSD Compress code was cleaned up in
an attempt to solve HP alignment problems.
* Thanks go to Pete French <pete@ohm.york.ac.uk> for all the
above modifications
New to release 0.4.3 (LKS version 4.4)
======================================
* This release fixes some problems regarding
HP and SPARC support. It is said to now run
on Sparc. I would hope HP also but havn't heard
yet. Thanks to Dave Hess <David-Hess@net.tamu.edu>
for finding the problems for Sparc.
* Minor documentation fixes.
New to release 0.4.0 (LKS version 4.1 - summerb2)
=================================================
* This release is based on the second beta release
of PPP-2.2 (ppp-2.2b2).
* The default chat is now the one supplied in the beta
PPP release. This chat will compile fine using Dev 3.3.
However, if you are running Dev 3.2, you will not be able
to compile the default chat (POSIX problems). In this case,
you may use the old chat (renamed as ./chat/chat.c.3.2).
New to release 0.4.0 (LKS version 4.0 - summerb1)
=================================================
* This release is based on the first beta release
of PPP-2.2 (ppp-2.2b1).
* Chat was updated in the new beta. However, because
of broken posix functionality under NeXTSTEP (3.2) it
will not compile properly. Therefore, the old chat
is being used. The newer chat is backed up as
./chat/chat.c.orig. Those with Dev 3.3 may wish to
try to compile to see if the posix problems were fixed.
* Support for the Microsoft Call Back Configuration Protocol.
See the file ./README.cbcp.
New to release 0.3.0 (LKS version 3.0 - summera51)
=====================================
* This release is the first to be based on the fifth alpha
release of PPP-2.2 (ppp-2.2a5).
* Major kernel revision. This release attempts to merge
the LKS written by Perkins and that written by Prindeville/French.
The hope is that this new merged kernel will allow us to maintain
one set of sources. This kernel, or a variant thereof, will
probably be the one that is released with the PPP-2.2 beta
distribution.
* Fixed a bug that caused problems with NXFax's capability
to determine port usage.
* Added support for the Berkley Packet Filter (BPF) and tcpdump.
Use of BPF requires special installation instructions. See
the installation file for more info.
* Fixed a header include problem that kept sources from compiling
under NS 3.3 Dev. for m68k. *Sigh* I guess support for m68k
continues to falter... :(
* Officially changed the name of the log file from:
/usr/adm/ppp2.2.debug
-to-
/usr/adm/ppp2.2.log
If you are upgrading, you should change the name of the file
in /etc/syslog.conf. Remember to watch out for the tab character
and remember to create the initial file. For more information see
./NeXT/INSTALL.
This change was done so that the file could be opened from the
workspace. There was a naming conflict with the .debug extension.
Note also, that this name is a bit different than that suggested in
the ./SETUP file.
* Fixed a problem with the pppd option 'local'.
As part of a5:
* Fixed a bug in pppd that would allow service (under some circumstances)
to peers who refuse to authenticate.
* Fixed a bug with CCP negotiation.
* Fixed a bug that caused negotation with an NT RAS PPP server to fail.
New to release 1.9 (LKS version 2.1)
=====================================
* Support for NS Sparc has been added. Sparc users note, the SUN
serial driver in the pre-release was not very robust at high speeds.
This has been fixed for the final release. This could cause problems
with testing on Sparc. Low bps rates should be OK...like 2400 to
maybe 9600 with low system activity. Thanks go to
John Landwehr <John_Landwehr@NeXT.COM> for this work.
* Fixed a nasty little bug that degraded performance of multiple
interfaces on Intel systems.
* Added support for IP address filtering. This allows
detection and prevetion of IP address spoofing. Check out
the new ./pppexclude directory. Thanks to
Lawrence E. Freil <lef@woods.com> for this code.
* More support for multiple ppp connections to different
hosts. Check out ./Examples/ppp_multiple_hosts.tar.gz.
Thanks to Jonathan Adams <jonathan@filoli.com> for this
code.
* Modified lock file for better UUCP interaction. Special
thanks to Kim Shrier <kim@tinker.com> for this code.
* Fixed the new 3.3 multicast warning.
* Improved installation documentation.
New to release 1.8 (LKS version 1.3)
=====================================
* Moved to ppp-2.2a4, the fourth alpha release
from Paul Mackerras <Paul.Mackerras@cs.anu.edu.au>.
* Fixed a bug that I introduced in 1.7 that could cause
kernel panics when BSD compression was used in conjunction
with VJ header compression.
* LKS Numbering Scheme changed (due to my screwup with a4 and CVS).
* Removed support for extra pppd option 'usepty'. Can be done
with an external program if desired.
* Included the old modified pppstats.c that shows compression
statistics.
New to release 1.7 (LKS version 1.31)
=====================================
* Moved packet compression outside the interrupt handler.
Previously, only packet decompression was done outside.
* Made many enhancements as suggested by Paul Mackerras.
* Fixed a bug that sometimes caused "bad fcs" errors to panic
the machine.
* Fixed a problem that caused NFS traffic to force
compression to exit (and sometimes hang NFS).
NFS traffic works properly now (regardless of the buffer size
set via the NFSManager.app).
* Fixed a timeout problem in pppd that could sometimes cause
negotiations to loop endlessly. This fix should eventually make
it into ppp2.2a4.
* Split code into multiple files for better organization.
* Fixed pppstats to show compression ratios on the proper
side. Left side is for incoming packets and right side is
for outgoing packets.
* Added some suggested enhancements to
pppd. These suggestions were brought up
on the ports mailing list and will probably
be included in ppp2.2a4. I added them for
the interrim. They basically involve better permissions
for running the ip-up and ip-down scripts. They are now run
as the effective user-id of pppd. So if you run pppd suid,
root, then ip-up and ip-down are run as root.
* Corrected several minor documentation problems.
New to release 1.6 (LKS version 1.24)
=====================================
* Added support for HP-PA systems. Many thanks go to
Alain Fauconnet <af@biomath.jussieu.fr> for his efforts in this
work.
* Added further performance enhancements to the LKS. This resulted
in fewer "silo overflows", and thus dropped packets, when operating
at high speed (>= 38.4KBS) sustained bidirectional transfers over
multiple interfaces.
* Updated the installation instructions.
New to release 1.5 (LKS version 1.22)
=====================================
* Not a real release. Used for distributing
tests to HPPA users.
New to release 1.4 (LKS version 1.18)
=====================================
* Fixed problem that delayed many PPP protcol packets from timely
delivery to pppd.
* Added compression statistics support for pppstats.
* Cleaned up processor priority levels.
* Added better support for netbuf queue monitoring.
New to release 1.3 (LKS version 1.16)
=====================================
* At compile time, you have the option to decompress VJ/BSD
packets either inside or outside the interrupt handler.
See the DECOMP_OUT flag in ./NeXT/Makefile. The old
functionality was to do the work inside the interrupt
handler. It is probably more appropriate to do it
outside. Thanks to Pete French <pete@ohm.york.ac.uk> for
discussion on this topic.
* Added initial support for operation over pseudo
ttys. See the USEPTY flag in ./pppd/Makefile.NeXT.
This adds a new option to pppd, "usepty <hostname>".
If this option is used, pppd will fire up an rlogin
session to <hostname>. You may then use chat as normal
to start the remote ppp. Thereafter, the packets flow
over the rlogin session. This may potentially be used
to start a new ppp session over an open ppp session.
* Added enhancements and changes suggested for ppp-2.2a3.
This includes some fixes to the BSD compression code
that caused it to turn off compression inappropriately
under error conditions.
* Patched pppd to better support code that sleeps but never
wakes in ip-up scripts. Thanks to longyear@netcom.com
(Al Longyear) and Bill Hay <wish@dumain.demon.co.uk>.
* Did more verification with the full version of NXFAX installed.
Seems to work flawlessly! Thanks to Rick Damon <nxfax@bandw.com>
at Black and White for his help in the matter.
* Added a new 'Examples' directory to the hierarchy. This
will become a collecting place for user info.
New to release 1.2 (LKS version 1.13)
=====================================
* The system now supports BSD Packet compression using the new CCP.
Of course, both ends must negotiate this option.
New to release 1.1
==================
* The system now works with the MuX serial driver V1.5. Probably
version 1.4 also. No changes need to be made to the MuX buffer
(and DOUBLE_BUFFER) values.
* The system now works when NXFax is installed.
* There have been some internal optimizations for those
who use the NeXT supplied serial drivers.
New to release 1.0
==================
* On Intel systems, some ioctl calls did not return the proper value.
This turned out to be a bug in the OS. A true workaround has been
implemented. The ioctl return value macro is now only used to
check for return value errors. Flags are now correctly set without
the macro.
* Multiple interfaces now work properly. The ioctl fix above solved
the problem of a second interface "stealing" the first interface.
* lcp-echo-failure works.
* We are now using the default pppstats. This was modified to
use an ioctl to get information. One less program we have to
support. pppstats no longer requires the SUID bit or the loadable.
* We are now using the default VJ compression code. Another
file we do not have to support.
* PPP-2.2 uses a new mechanism for determining when to kill pppd.
This should solve the process group problems we have been
experiencing.
* Compression is not yet implemented. This release should give you
the same (but more stable) functionality as the ppp-2.1.2 release.
