This file describes the installation process for ppp-2.3 on systems running Solaris 2. The Solaris 2 and SVR4 ports share a lot of code but are not identical. The STREAMS kernel modules and driver for Solaris 2 are in the svr4 directory (and use some code from the modules directory). This version has been tested under Solaris 2.6. NOTE: Although the kernel driver and modules have been designed to operate correctly on SMP systems, they have not been extensively tested on SMP machines. Some users of SMP Solaris x86 systems have reported system problems apparently linked to the use of previous versions of this software. I believe these problems have been fixed. Installation. ************* 1. Run the configure script and make the user-level programs and the kernel modules. ./configure make If you wish to use gcc (or another compiler) instead of Sun's cc, edit the svr4/Makedefs file and uncomment the definition of CC. You can also change the options passed to the C compiler by editing the COPTS definition. 2. Install the programs and kernel modules: as root, do make install This installs pppd, chat and pppstats in /usr/local/bin and the kernel modules in /kernel/drv and /kernel/strmod, and creates the /etc/ppp directory and populates it with default configuration files. You can change the installation directories by editing svr4/Makedefs. If your system normally has only one network interface, the default Solaris 2 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 and /dev/zsh drivers. Synchronous mode was tested with a Cisco router. There ppp daemon does not directly support controlling the serial interface. It relies on the /usr/sbin/syncinit command to initialize HDLC mode and clocking. Some bugs remain: large sized frames are not sent/received properly, and may be related to the IP mtu. This may be due to bugs in pppd itself, bugs in Solaris or the serial drivers. The /dev/zsh driver seems more larger and can send/receive larger frames than the /dev/se_hdlc driver. There is a confirmed bug with NRZ/NRZI mode in the /dev/se_hdlc driver, and Solaris patch 104596-11 is needed to correct it. (However this patch seems to introduce other serial problems. If you don't apply the patch, the workaround is to change the nrzi mode to yes or no, whichever works) 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" Sample Cisco router config excerpt: ! !
