 Point-to-Point Protocol (PPP) to provide Internet connections over

+In this first beta release, the ports for SunOS, Solaris, NetBSD and

+port mostly works, but still has some known bugs (demand dialling
+doesn't work correctly).  The remaining ports haven't been tested

-The Point-to-Point Protocol (PPP) provides a standard way to transmit
-datagrams over a serial link, as well as a standard way for the
-machines at either end of the link (the `peers') to negotiate various
-optional characteristics of the link.  Using PPP, a serial link can be
-used to transmit Internet Protocol (IP) datagrams, allowing TCP/IP
-connections between the peers.  PPP is defined in several RFC (Request
-For Comments) documents, in particular RFCs 1661, 1662, 1332 and 1334.
-Other RFCs describe standard ways to transmit datagrams from other
-network protocols (e.g., DECnet, OSI, Appletalk), but this package
-only supports IP.
+The Point-to-Point Protocol (PPP) provides a standard way to establish

+supports IP and the protocols layered above IP, such as TCP and UDP.
+The Linux port of this package also has support for IPX.

-What is new in ppp-2.2.
-***********************
+What's new in ppp-2.3.
+**********************
+
+* Demand-dialling.  Pppd now has a mode where it will establish the
+network interface immediately when it starts, but not actually bring
+the link up until it sees some data to be sent.  Look for the demand
+option description in the pppd man page.

 
 

-* More systems are now supported:
+* Idle timeout.  Pppd will optionally terminate the link if no data
+packets are sent or received within a certain time interval.

 
 

-  AIX 4, thanks to Charlie Wick (cwick@quaver.urbana.mcd.mot.com)
-  OSF/1 on DEC Alpha, thanks to Steve Tate (srt@zaphod.csci.unt.edu)
-  NextStep 3.2 and 3.3, thanks to Philip-Andrew Prindeville
-       (philipp@res.enst.fr) and Steve Perkins (perkins@cps.msu.edu)
+* Pppd now runs the /etc/ppp/auth-up script, if it exists, when the
+peer successfully authenticates itself, and /etc/ppp/auth-down when
+the connection is subsequently terminated.  This can be useful for
+accounting purposes.

 
 

-in addition to NetBSD 1.0, SunOS 4.x, Ultrix 4.x, FreeBSD 2.0, and
-Linux.
+* A new packet compression scheme, Deflate, has been implemented.
+This uses the same compression method as `gzip'.  This method is free
+of patent or copyright restrictions, and it achieves better
+compression than BSD-Compress.  It does consume more CPU cycles for
+compression than BSD-Compress, but this shouldn't be a problem for
+links running at 100kbit/s or less.

 
 

-* Packet compression has been implemented.  This version implements
-CCP (Compression Control Protocol) and the BSD-Compress compression
-scheme according to the current draft RFCs.  This means that incoming
-and outgoing packets can be compressed with the LZW scheme (same as
-the `compress' command) using a code size of up to 15 bits.
+* There is no code in this distribution which is covered by Brad
+Clements' restrictive copyright notice.  The STREAMS modules for SunOS
+and OSF/1 have been rewritten, based on the Solaris 2 modules, which
+were written from scratch without any Clements code.

 
 

-* Some bug fixes to the LCP protocol code.  In particular, pppd now
-correctly replies with a Configure-NAK (instead of a Configure-Reject)
-if the peer asks for CHAP and pppd is willing to do PAP but not CHAP.
+* Pppstats has been reworked to clean up the output format somewhat.
+It also has a new -d option which displays data rate in kbyte/s for
+those columns which would normally display bytes.

 
 

-* The ip-up and ip-down scripts are now run with the real user ID set
-to root, and with an empty environment.  Clearing the environment
-fixes a security hole.
+* Pppd options beginning with - or + have been renamed, e.g. -ip
+became noip, +chap became require-chap, etc.  The old options are
+still accepted for compatibility but may be removed in future.

 
 

-* The kernel code on NetBSD, FreeBSD, NextStep and Ultrix has been
-restructured to make it easier to implement PPP over devices other
-than asynchronous tty ports (for example, synchronous serial ports).
+* Pppd now has some options (such as the new `noauth' option) which
+can only be specified if it is being run by root, or in an
+"privileged" options file: /etc/ppp/options or an options file in the
+/etc/ppp/peers directory.  There is a new "call" option to read
+options from a file in /etc/ppp/peers, making it possible for non-root
+users to make unauthenticated connections, but only to certain trusted
+peers.  My intention is to make the `auth' option the default in a
+future release.

 
 

-* pppd now looks at the list of interfaces in the system to determine
-what the netmask should be.  In most cases, this should eliminate the
-need to use the `netmask' option.
+* Several minor new features have been added to pppd, including the
+maxconnect and welcome options.  Pppd will now terminate the
+connection when there are no network control protocols running.  The
+allowed IP address(es) field in the secrets files can now specify
+subnets (with a notation like 123.45.67.89/24) and addresses which are
+not acceptable (put a ! on the front).

 
 

-* There is a new `papcrypt' option to pppd, which specifies that
-secrets in /etc/ppp/pap-secrets used for authenticating the peer are
-encrypted, so pppd always encrypts the peer's password before
-comparing it with the secret from /etc/ppp/pap-secrets.  This gives
-better security.
+* Numerous bugs have been fixed (no doubt some have been introduced :-)
+Thanks to those who reported bugs in ppp-2.2.
