3 | # This example script retrieves the DHCP state of a given interface. | |
4 | # In the interest of keeping the KVP daemon code free of distro specific | |
5 | # information; the kvp daemon code invokes this external script to gather | |
6 | # DHCP setting for the specific interface. | |
7 | # | |
8 | # Input: Name of the interface | |
9 | # | |
10 | # Output: The script prints the string "Enabled" to stdout to indicate | |
11 | # that DHCP is enabled on the interface. If DHCP is not enabled, | |
12 | # the script prints the string "Disabled" to stdout. | |
13 | # | |
14 | # Each Distro is expected to implement this script in a distro specific | |
15 | # fashion. | |
