Introduction.
*************
This file describes the installation process for ppp-2.5 on systems
running an OpenSolaris-derived OS, such as Illumos or OpenIndiana.
For these systems, the STREAMS kernel modules are supplied with the
OS itself and are used as-is by this distribution. For more
information on these distributions (including kernel source) see:
https://www.illumos.org/
https://illumos.org/docs/about/distro/
For Oracle Solaris systems, either use the vendor-supplied PPP
implementation ("Solaris PPP 4.0" based on pppd-2.4.0), or download
an older version of the pppd sources here:
https://download.samba.org/pub/ppp/
The last version known to compile and run correctly on Oracle
Solaris 10 is pppd-2.4.8. It may be possible to compile and use
newer versions on either Solaris 11 or by installing third-party
compilers; this has not been tested.
Installation.
*************
1. Make sure you have a suitable compiler installed. This package was
tested with "pkg install gcc-14" but other modern compilers should
work.
2. Run the configure script and build the package.
./configure --with-runtime-dir=/var/run --with-logfile-dir=/var/log/ppp
make
The configure script will automatically find the compiler if it's in
the standard location (/usr/bin/gcc). By default, everything will be
installed in /usr/local. Use "--prefix" to choose a different
installation directory if desired. Use "./configure -h" to see other
options.
3. Install the programs.
sudo make install
This installs the following:
/usr/local/sbin pppd, chat, pppstats, pppdump
/usr/local/share/man/man8 man pages
/usr/local/include/pppd plug-in header files
/usr/local/lib/pppd/$VER plug-in modules
/usr/local/etc/ppp example configuration files
If your system normally has only one network interface at boot
time, the default Solaris system startup scripts will disable IP
forwarding in the IP kernel module. This will prevent the remote
machine from using the local machine as a gateway to access other
hosts. The solution is to create an /etc/ppp/ip-up script
containing something like this:
#!/bin/sh
/usr/sbin/ndd -set /dev/ip ip_forwarding 1
See the man page for ip(7p) for details.
Synchronous Serial Support.
***************************
This version has working but limited support for the on-board
synchronous HDLC interfaces. It has been tested with the
/dev/se_hdlc, /dev/zsh, HSI/S, and HSI/P drivers. Synchronous mode
was tested with a Cisco router.
The ppp daemon does not directly support controlling the serial
interface. It relies on the OS-supplied /usr/sbin/syncinit command
to initialize HDLC mode and clocking.
How to start pppd with synchronous support:
#!/bin/sh
local=1.1.1.1 # your ip address here
baud=38400 # needed, but ignored by serial driver
# Change to the correct serial driver/port
#dev=/dev/zsh0
dev=/dev/se_hdlc0
# Change the driver, nrzi mode, speed and clocking to match
# your setup.
# This configuration is for external clocking from the DCE
connect="syncinit se_hdlc0 nrzi=no speed=64000 txc=rxc rxc=rxc"
/usr/sbin/pppd $dev sync $baud novj noauth $local: connect "$connect"
