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 + . 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. + +* A workaround to avoid tickling a bug in the `se' serial port driver +on Sun PCI Ultra machines running Solaris. + +* Fixed a bug in the negotiation of the Microsoft WINS server address +option. + +* Fixed a bug in the Linux port where it would fail for kernel +versions above 2.1.99. + + +What was new in ppp-2.3.4. +************************** + +* The NeXT port has been updated, thanks to Steve Perkins. + +* ppp-2.3.4 compiles and works under Solaris 2.6, using either gcc or +cc. + +* With the Solaris, SVR4 and SunOS ports, you can control the choice +of C compiler, C compiler options, and installation directories by +editing the svr4/Makedefs or sunos4/Makedefs file. + +* Until now, we have been using the number 24 to identify Deflate +compression in the CCP negotiations, which was the number in the draft +RFC describing Deflate. The number actually assigned to Deflate is +26. The code has been changed to use 26, but to allow the use of 24 +for now for backwards compatibility.
