for authentication, so you can control which other systems may make a
PPP connection and what IP addresses they may use.
-The primary platforms supported by this package are Linux and Solaris.
-Code for SunOS 4.x is included here but is largely untested. I have
-code for NeXTStep, FreeBSD, SVR4, Tru64 (Digital Unix), AIX and Ultrix
-but no active maintainers for these platforms. Code for all of these
-except AIX is included in the ppp-2.3.11 release.

Installation.
Solaris README.sol2
In each case you start by running the ./configure script. This works
-out which operating system you are using and creates symbolic links to
-the appropriate makefiles. You then run `make' to compile the
-user-level code, and (as root) `make install' to install the
-user-level programs pppd, chat and pppstats.

N.B. Since 2.3.0, leaving the permitted IP addresses column of the
pap-secrets or chap-secrets file empty means that no addresses are
authenticating itself to you, of course.)
-What's new in ppp-2.4.2.
+What's new in ppp-2.4.3.
************************
+* The configure script now accepts --prefix and --sysconfdir options.
+ These default to /usr/local and /etc. If you want pppd put in
+ /usr/sbin as before, use ./configure --prefix=/usr.
+
+* Doing `make install' no longer puts example configuration files in
+ /etc/ppp. Use `make install-etcppp' if you want that.
+
+* The code has been updated to work with version 0.8.3 of libpcap.
+ Unfortunately the libpcap maintainers removed support for the
+ "inbound" and "outbound" keywords on PPP links, meaning that if you
+ link pppd with libpcap-0.8.3, you can't use those keywords in the
+ active-filter and pass-filter expressions. The support has been
+ reinstated in the CVS version and should be in future libpcap
+ releases. If you need the in/outbound keywords, use a later release
+ than 0.8.3, or get the CVS version from http://www.tcpdump.org.
+
+* There is a new option, child-timeout, which sets the length of time
+ that pppd will wait for child processes (such as the command
+ specified with the pty option) to exit before exiting itself. It
+ defaults to 5 seconds. After the timeout, pppd will send a SIGTERM
+ to any remaining child processes and exit. A value of 0 means no
+ timeout.
+
+* Various bugs have been fixed, including some CBCP packet parsing
+ bugs that could lead to the peer being able to crash pppd if CBCP
+ support is enabled.
+
+* Various fixes and enhancements to the radius and rp-pppoe plugins
+ have been added.

* The CHAP code has been rewritten. Pppd now has support for MS-CHAP
V1 and V2 authentication, both as server and client. The new CHAP
code is cleaner than the old code and avoids some copyright problems
include Predictor, LZS, and MPPC. These methods are not supported for
two reasons - they are patent-encumbered, and they cause some packets
to expand slightly, which pppd doesn't currently allow for.
-BSD-Compress is also patent-encumbered (its inclusion in this package
-can be considered a historical anomaly :-) but it doesn't ever expand
-packets. Neither does Deflate, which uses the same algorithm as gzip.

Patents.
********
The BSD-Compress algorithm used for packet compression is the same as
-that used in the Unix "compress" command. It is apparently covered by
-U.S. patents 4,814,746 (owned by IBM) and 4,558,302 (owned by Unisys),
-and corresponding patents in various other countries (but not
-Australia). If this is of concern, you can build the package without
-including BSD-Compress. To do this, edit net/ppp-comp.h to change the
-definition of DO_BSD_COMPRESS to 0. The bsd-comp.c files are then no
-longer needed, so the references to bsd-comp.o may optionally be
-removed from the Makefiles.
