What was 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.
|
|
|
|
* 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. (This can be disabled with the
|
|
`nodeflatedraft' option to pppd.)
|
|
|
|
* Fixed some bugs in the linux driver and deflate compressor which
|
|
were causing compression problems, including corrupting long
|
|
incompressible packets sometimes.
|
|
|
|
* Fixes to the PAM and shadow password support in pppd, from Al
|
|
Longyear and others.
|
|
|
|
* Pppd now sets some environment variables for scripts it invokes
|
|
(ip-up/down, auth-ip/down), giving information about the connection.
|
|
The variables it sets are PEERNAME, IPLOCAL, IPREMOTE, UID, DEVICE,
|
|
SPEED, and IFNAME.
|
|
|
|
* Pppd now has an `updetach' option, which will cause it to detach
|
|
from its controlling terminal once the link has come up (i.e. once it
|
|
is available for IP traffic).
|
|
|
|
|
|
What was new in ppp-2.3.3.
|
|
**************************
|
|
|
|
* Fixed compilation problems under SunOS.
|
|
|
|
* Fixed a bug introduced into chat in 2.3.2, and compilation problems
|
|
introduced into the MS-CHAP implementation in 2.3.2.
|
|
|
|
* The linux kernel driver has been updated for recent 2.1-series
|
|
kernel changes, and it now will ask kerneld to load compression
|
|
modules when required, if the kernel is configured to support kerneld.
|
|
|
|
* Pppd should now compile correctly under linux on systems with glibc.
|
|
|
|
|
|
What was new in ppp-2.3.2.
|
|
**************************
|
|
|
|
* In 2.3.1, I made a change which was intended to make pppd able to
|
|
detect loss of CD during or immediately after the connection script
|
|
runs. Unfortunately, this had the side-effect that the connection
|
|
script wouldn't work at all on some systems. This change has been
|
|
reversed.
|
|
|
|
* Fix compilation problems in the Linux kernel driver.
|
|
|
|
|
|
What was new in ppp-2.3.1.
|
|
**************************
|
|
|
|
* Enhancements to chat, thanks to Francis Demierre. Chat can now
|
|
accept comments in the chat script file, and has new SAY, HANGUP,
|
|
CLR_ABORT and CLR_REPORT keywords.
|
|
|
|
* Fixed a bug which causes 2.3.0 to crash Solaris systems.
|
|
|
|
* Bug-fixes and restructuring of the Linux kernel driver.
|
|
|
|
* The holdoff behaviour of pppd has been changed slightly: now, if
|
|
the link comes up for IP (or other network protocol) traffic, we
|
|
consider that the link has been successfully established, and don't
|
|
enforce the holdoff period after the link goes down.
|
|
|
|
* Pppd should now correctly wait for CD (carrier detect) from the
|
|
modem, even when the serial port initially had CLOCAL set, and it
|
|
should also detect loss of CD during or immediately after the
|
|
connection script runs.
|
|
|
|
* Under linux, pppd will work with older 2.2.0* version kernel
|
|
drivers, although demand-dialling is not supported with them.
|
|
|
|
* Minor bugfixes for pppd.
|
|
|
|
|
|
What was 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. Demand-dialling is not
|
|
supported under Ultrix or NeXTStep.
|
|
|
|
* Idle timeout. Pppd will optionally terminate the link if no data
|
|
packets are sent or received within a certain time interval.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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).
|
|
|
|
* Numerous bugs have been fixed (no doubt some have been introduced :-)
|
|
Thanks to those who reported bugs in ppp-2.2.
