Creating Interfaces

Interface creation for PPP is usually performed by including commands in the sysadm.ini file that you build into the ChorusOS system image for your target. In order to create a PPP interface, use the mkdev(1M) utility as follows:

mkdev ppp unit

where unit is the number that makes the interface unique. In order to allow the system to use IP, you must also create a loopback interface.

Example 11-1 PPP Interface Creation

The following example sysadm.ini fragment creates a PPP interface and the loopback interface needed for IP communication. These commands simply create the interface; nothing is configured for use, yet.

# Create a PPP interface
mkdev ppp 0
