Configuration Files

This section describes all files which must be created or modified to configure PPP on a Solaris host.

Configuring the Network

1. If you are using aliases for your IP addresses, it is important to ensure that the Solaris operating environment can resolve them. In /etc/hosts, include the following lines:

   # Host PPP address Host PPP hostname
   host_PPP host_name
   # Target PPP address Target PPP hostname
   target_PPP target_name
   

Make sure /etc/hosts or the NIS configuration file, nsswitch.conf(4) includes PPP addresses for both the host and target systems. The nsswitch.conf file explains how to configure /etc/hosts.

Configuring PPP

You must provide the PPP Link Manager with information regarding each remote host with which the local host will communicate. This information is contained in the PPP configuration file asppp.cf. See also aspppls(1M).

Configure asppp.cf as follows:

1. Run ifconfig, specify the PPP interface used, select the plumb option to enable IP to recognize the interface, define the local and target hosts and set the interface to up :

   ifconfig ipdptp0 plumb host_PPP target_PPP up

   See "ifconfig" for more information about the ifconfig command.

2. Configure the path by adding the interface number, the name of the target host, the ipcp_async_map and the timeout interval:

   path
    interface ipdptp0
    peer_system_name .zsmon
    ipcp_async_map 0xa000
    inactivity_timeout 1000000

For further information regarding configuring PPP and the asppp.cf file, see "Configuring PPP" in TCP/IP and Data Communications Administration Guide from the Solaris 7 System Administrator Collection and "Overview of PPP" in System Administration Guide, Volume 3 from the Solaris 8 System Administrator Collection. There is also useful information in aspppd(1M)
