files, are:
- Digital Unix (OSF/1) README.osf
Linux README.linux
+ Solaris 2 README.sol2
+ Digital Unix (OSF/1) README.osf
NetBSD, FreeBSD README.bsd

Ultrix 4.x README.ultrix
-Unfortunately, AIX 4 is no longer supported, since I don't have a
-maintainer for the AIX 4 port. If you want to volunteer, contact me.
-The Ultrix port is untested, as I no longer have access to an Ultrix
-box.
+In fact, only the Linux and Solaris 2 ports have been tested in this
+release. Code for the other systems is still included; if you use it,
+let me know how it works. If I don't hear from anyone it will
+probably get dropped in a subsequent release. AIX 4 is no longer
+supported, since I don't have a maintainer for the AIX 4 port. If you
+want to volunteer, contact me.
In each case you start by running the ./configure script. This works
out which operating system you are using and creates symbolic links to
authenticating itself to you, of course.)
-What's new in ppp-2.3.5.
-************************
+What's new in ppp-2.3.11.
+*************************
+
+* Support for Solaris 8 has been added, including support for
+ replumbing and IPV6.
+
+* The Solaris `snoop' utility should now work on ppp interfaces.
+
+* New hooks have been added - pap_logout_hook, ip_up_hook, and
+ ip_down_hook.
+
+* A new `passprompt' plugin is included, thanks to Alan Curry, which
+ makes it possible for pppd to call an external program to get the
+ PAP password to send to the peer.
+
+* The error messages for the situation where authentication is
+ required because the system has a default route have been improved.
+
+* There is a new connect_delay option which specifies how long pppd
+ should pause after the connect script finishes. Previously this
+ delay was fixed at 1 second. (This delay terminates as soon as pppd
+ sees a valid PPP frame from the peer.)
+
+* The `hide-password' option is now the default, and there is a new
+ `show-password' option to enable the printing of password strings in
+ the debug output.
+
+* A fairly complete list of the names of PPP protocols has been added
+ so that when pppd rejects a frame because its protocol is not
+ supported, it can print the name of the unsupported protocol.
+
+* Synchronous serial lines are supported under Linux 2.3.x.
+
+* The bug where pppd would not recognize a modem hangup under Linux
+ 2.3.x kernels has been fixed.
+
+
+What was new in ppp-2.3.10.
+***************************
+
+* Pppd now supports `plugins', which are pieces of code (packaged as
+ shared libraries) which can be loaded into pppd at runtime and which
+ can affect its behaviour. The intention is that plugins provide a
+ way for people to customize the behaviour of pppd for their own
+ needs without needing to change the base pppd source. I have added
+ some hooks into pppd (places where pppd will call a function
+ pointer, if non-zero, to replace some of pppd's code) and I will be
+ receptive to suggestions about places to add more hooks. Plugins
+ are supported under Linux and Solaris at present.
+
+* We have a new maintainer for the Solaris port, Adi Masputra of Sun
+ Microsystems, and he has updated the Solaris port so that it should
+ work on 64-bit machines under Solaris 7 and later.
+
+* Pppd now has an `allow-ip' option, which takes an argument which is
+ an IP address (or subnet) which peers are permitted to use without
+ authenticating themselves. The argument takes the same form as each
+ element of the allowed IP address list in the secrets files. The
+ allow-ip option is privileged and may be specified multiple times.
+ Using the allow-ip option should be cleaner than putting a line like
+ `"" * "" address' in /etc/ppp/pap-secrets.
+
+* Chat can now substitute environment variables into the script. This
+ is enabled by the -E flag. (Thanks to Andreas Arens for the patch.)
+
+* If the PAP username and password from the peer contains unprintable
+ characters, they will be translated to a printable form before
+ looking in the pap-secrets file. Characters >= 0x80 are translated
+ to a M- form, and characters from 0 to 0x1f (and 0x7f as well) are
+ translated to a ^X form. If this change causes you grief, let me
+ know what would be a better translation. It appears that some peers
+ send nulls or other control characters in their usernames and
+ passwords.
+
+* Pppd has new `ktune' and `noktune' options, which enable/disable
+ it to change kernel settings as appropriate. This is only
+ implemented under Linux, and requires the /proc filesystem to be
+ mounted. Under Linux, with the ktune option, pppd will enable IP
+ forwarding in the kernel if the proxyarp option is used, and will
+ enable the dynamic IP address kernel option in demand mode if the
+ local IP address changes.
+
+* Pppd no longer requires a remote address to be specified for demand
+ dialling. If none is specified, it will use a default value of
+ 10.112.112.112+unit_number. (It will not propose this default to
+ the peer.)
+
+* The default holdoff is now 0 if no connect script is given.
+
+* The IPV6 code from Tommi Komulainen, which I unfortunately only
+ partially merged in to ppp-2.3.9, has been fixed and updated.
+
+* The linux compilation glitches should be fixed now.
+
+
+What was new in ppp-2.3.9.
+**************************
+
+* Support for the new generic PPP layer under development for the
+ Linux kernel.
+
+* You can now place extra options to apply to specific users at the
+ end of the line with their password in the pap-secrets or
+ chap-secrets file, separated from the IP address(es) with a "--"
+ separator. These options are parsed after the peer is authenticated
+ but before network protocol (IPCP, IPXCP) or CCP negotiation
+ commences.
+
+* Pppd will apply the holdoff period if the link was terminated by the
+ peer. It doesn't apply it if the link was terminated because the
+ local pppd thought it was idle.
+
+* Synchronous support for Solaris has been added, thanks to John
+ Morrison, and for FreeBSD, thanks to Paul Fulghum.
+
+* IPV6 support has been merged in, from Tommi Komulainen. At the
+ moment it only supports Linux and it is not tested by me.
+
+* The `nodefaultip' option can be used in demand mode to say that pppd
+ should not suggest its local IP address to the peer.
+
+* The `init' option has been added; this causes pppd to run a script
+ to initialize the serial device (e.g. by sending an init string to
+ the modem). Unlike the connect option, this can be used in a
+ dial-in situation. (Thanks to Tobias Ringstrom.)
+
+* There is a new `logfile' option to send log messages to a file as
+ well as syslog.
+
+* There is a new, privileged `linkname' option which sets a logical
+ name for the link. Pppd will create a /var/run/ppp-<linkname>.pid
+ file containing its process ID.
+
+* There is a new `maxfail' option which specifies how many consecutive
+ failed connection attempts are permitted before pppd will exit. The
+ default value is 10, and 0 means infinity. :-)
+
+* Sundry bugs fixed.
+
+
+What was new in ppp-2.3.8.
+**************************
+
+* The exit status of pppd will now indicate whether the link was
+ successfully established, or if not, what error was encountered.
+
+* Pppd has two new options: fdlog <n> will send log messages to file
+ descriptor <n> instead of standard output, and nofdlog will stop log
+ messages from being sent to any file descriptor (they will still be
+ sent to syslog). Pppd now will not send log messages to a file
+ descriptor if the serial port is open on that file descriptor.
+
+* Pppd sets an environment variable called PPPLOGNAME for scripts that
+ it runs, indicating the login name of the user who invoked pppd.
+
+* Pppd sets environment variables CONNECT_TIME, BYTES_SENT and
+ BYTES_RCVD for the ip-down and auth-down scripts indicating the
+ statistics for the connection just terminated. (CONNECT_TIME is in
+ seconds.)
+
+* If the user has the serial device open on standard input and
+ specifies a symbolic link to the serial device on the command line,
+ pppd will detect this and behave correctly (i.e. not detach from its
+ controlling terminal). Furthermore, if the serial port is open for
+ reading and writing on standard input, pppd will assume that it is
+ locked by its invoker and not lock it itself.
+
+* Chat now has a feature where if a string to be sent begins with an
+ at sign (@), the rest of the string is taken as the name of a file
+ (regular file or named pipe), and the actual string to send is taken
+ from that file.
+
+* Support for FreeBSD-2.2.8 and 3.0 has been added, thanks to Paul
+ Fulghum.
+
+* The Tru64 (aka Digital Unix aka OSF/1) port has been updated.
+
+* The system panics on Solaris SMP systems related to PPP connections
+ being established and terminated should no longer occur.
+
+* Fixed quite a few bugs.
+
+
+What was new in ppp-2.3.7.
+**************************
+
+* Pppd can now automatically allocate itself a pseudo-tty to use as
+ the serial device. This has made three new options possible:
+
+ - `pty script' will run `script' with its standard input and output
+ connected to the master side of the pty. For example:
+ pppd pty 'ssh -t server.my.net pppd'
+ is a basic command for setting up a PPP link (tunnel) over ssh.
+ (In practice you may need to specify other options such as IP
+ addresses, etc.)
+
+ - `notty' tells pppd to communicate over its standard input and
+ output, which do not have to be a terminal device.
+
+ - `record filename' tells pppd to record all of the characters sent
+ and received over the serial device to a file called `filename'.
+ The data is recorded in a tagged format with timestamps, which can
+ be printed in a readable form with the pppdump program, which is
+ included in this distribution.
+
+* Pppd now logs the connect time and number of bytes sent and received
+ (at the level of the serial device) when the connection is
+ terminated.
+
+* If you use the updetach or nodetach option, pppd will print its
+ messages to standard output as well as logging them with syslog
+ (provided of course pppd isn't using its standard input or output as
+ its serial device).
+
+* There is a new `privgroup groupname' option (a privileged option).
+ If the user running pppd is in group `groupname', s/he can use
+ privileged options without restriction.
+
+* There is a new `receive-all' option, which causes pppd to accept all
+ control characters, even the ones that the peer should be escaping
+ (i.e. the receive asyncmap is 0). This is useful with some buggy
+ peers.
+
+* The default asyncmap is now 0.
+
+* There is a new `sync' option, currently only implemented under
+ Linux, which allows pppd to run on synchronous HDLC devices.
+
+* If a value for the device name or for the connect, disconnect,
+ welcome or pty option is given in a privileged option file
+ (i.e. /etc/ppp/options or a file loaded with the `call' option), it
+ cannot be overridden by a non-privileged user.
+
+* Many bugs have been fixed, notably:
+ - signals are not blocked unnecessarily, as they were in 2.3.6.
+ - the usepeerdns option should work now.
+ - the SPEED environment variable for scripts is set correctly.
+ - the /etc/ppp/auth-down script is not run until auth-up completes.
+ - the device is opened as root if it is the device on standard
+ input.
+ - pppd doesn't die with the ioctl(PPPIOCSASYNCMAP) error under linux
+ if a hangup occurs at the wrong time.
+
+* Some error messages have been changed to be clearer (I hope :-)
+
+
+What was new in ppp-2.3.6.
+**************************
+
+* Pppd now opens the tty device as the user (rather than as root) if
+ the device name was given by the user, i.e. on the command line or
+ in the ~/.ppprc file. If the device name was given in
+ /etc/ppp/options or in a file loaded with the `call' option, the
+ device is opened as root.
+
+* The default behaviour of pppd is now to let a peer which has not
+ authenticated itself (e.g. your ISP) use any IP address to which the
+ system does not already have a route. (This is currently only
+ supported under Linux, Solaris and Digital Unix; on the other
+ systems, the peer must now authenticate itself unless the noauth
+ option is used.)
+
+* Added new option `usepeerdns', thanks to Nick Walker
+ <nickwalker@email.com>. If the peer supplies DNS addresses, these
+ will be written to /etc/ppp/resolv.conf. The ip-up script can then
+ be used to add these addresses to /etc/resolv.conf if desired (see
+ the ip-up.local.add and ip-down.local.add files in the scripts
+ directory).
+
+* The Solaris ppp driver should now work correctly on SMP systems.
+
+* Minor corrections so that the code can compile under Solaris 7,
+ and under Linux with glibc-2.1.
+
+* The Linux kernel driver has been restructured for improved
+ performance.
+
+* Pppd now won't start the ip-down script until the ip-up script has
+ finished.
+
+
+What was new in ppp-2.3.5.
+**************************
* Minor corrections to the Digital UNIX and NetBSD ports.
Thanks to those who reported bugs in ppp-2.2.
+Compression methods.
+********************
+
+This package supports two packet compression methods: Deflate and
+BSD-Compress. Other compression methods which are in common use
+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.
