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 2.5.1 and 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 this software. 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 2 Under Solaris 2.6, the value 2 is invalid; use 1 instead. See the man page for ip(7p) for details.
