Interface Creation

As described in "Interface Creation", interface creation 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 SLIP interface, use the mkdev(1M) utility as follows:

mkdev sl 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 5-1 SLIP Interface Creation

The following example sysadm.ini fragment creates a SLIP interface and the loopback interface needed for IP communication.

#
# Set the file creation mask to 0 during system configuration
#
umask 0

#
# Create a SLIP interface
#
mkdev sl 0

#
# Create a loopback interface
#
mkdev lo 0

Note that the above commands simply create the interface; nothing is configured for use, yet.
