Configuring PPP

The Solaris PPP daemon, aspppd, is started automatically at boot time if the /etc/asppp.cf is present. The file contains the configuration parameters for the PPP system. You will need to edit or create this file before you can use PPP.

The following procedure, with minor changes, will create a configuration file that should work in most cases.

1. Obtain the following information:

   • An IP address/name that can be used for PPP. If your SPARCstation Voyager is connected to the Ethernet, then this will be a second, and different, IP address from the Ethernet IP address. In the following example we use "voyager."

   • The IP address/name for the remote PPP server you will be connecting to. In the following example, we use "PPPserver."

2. Add lines similar to the following to the /etc/inet/hosts file:

   ---

   192.11.117.26     voyager
   192.26.32.114     PPPserver
   

   ---

   Be sure you use the actual names and addresses you obtained in Step 1.

3. Add lines similar to the following lines to the /etc/asppp.cf file:

   ---

   ifconfig ipdptp0 plumb voyager PPPserver private up
   path
   interface ipdptp0
   peer_system_name PPPserver
   inactivity_timeout 300
   debug_level 5
   

   ---

Again, use the actual names you obtained in Step 1.

You can leave out the inactivity_timeout line if you want to use the default timeout of 120 seconds. The above specifies a timeout of 300 seconds. You can also leave out the debug_level line, or change its value depending on the how much information you want reported in the /var/adm/log/asppp.log file.

See the PPP man page, aspppd, the ifconfig man page, and the relevant chapters in SunOS 5.3 Administering TCP/IP and PPP for a more thorough discussion of the contents of the /etc/asppp.cf file.
