The skipif command is used to install SKIP on a network interface.
If you are adding SunScreen SKIP to a machine with only one interface, make sure that you are root and type:
# skipif -a |
If you are adding SunScreen SKIP to a machine with multiple interfaces, make sure that you are root and type:
# skipif -i networkinterface -a |
Replace networkinterface with the interface that you wish to specify. If you do not specify the network interface, it attaches to the first network interface that it finds.
You can add SKIP on more than one interface. In that case, you need to run the skipif -a -i interface command for each interface on which you want to use SKIP.
If you want to use SKIP on all the network interfaces present in the system, type:
# skipif -a -i all |
