DHCP Server Start Stop Script
#!/bin/bash
# /usr/local/bin/dhcpmgmt.sh
function start {
sudo /bin/launchctl load -w /System/Library/LaunchDaemons/bootps.plist
}
function stop {
sudo /bin/launchctl unload -w /System/Library/LaunchDaemons/bootps.plist
}
case "$1" in
"start")
echo "Starting DHCP Server"
start
;;
"stop")
echo "Stopping DHCP Server"
stop
;;
"status")
echo "Checking status"
sudo launchctl list com.apple.bootpd
;;
"leases"|"l")
echo "Viewing leases"
cat /var/db/dhcpd_leases
;;
*)
echo "Usage:"
echo dhcp-tgn start\|stop\|leases\|lstatus
echo .
;;
esac
The important bits are change your bootpd.plist to point to the correct interface (mine is en7), add a static ip to it (e.g. 10.77.80.1) and modify the range and other settings to work for you.
