Register new agent on server with isc-dhcp

su stork-agent -s /bin/sh -c 'stork-agent register --server-url http://10.0.0.117:8080'

Control from command line

“Single quotes (‘ ‘) operate similarly to double quotes, but do not permit referencing variables, since the special meaning of $ is turned off. Within single quotes, every special character except ‘ gets interpreted literally.

Encapsulating “!” within double quotes gives an error when used from the command line. This is interpreted as a history command. Within a script, though, this problem does not occur, since the Bash history mechanism is disabled then.”

Release an ip

curl -u ‘[USERNAME]:[PASSWORD]’ -X POST -H “Content-Type: application/json” -d ‘{ “command”: “lease4-del”, “service”: [“dhcp4”],”arguments”: { “ip-address”: “192.168.1.103” } }’ http://localhost:8000/

Reclaim ips

curl -u ‘[user]:[pass]’
-H “Content-Type: application/json”
-d ‘{ “command”: “leases-reclaim”, “service”: [ “dhcp4” ], “arguments”: { “remove”: true } }’
http://127.0.0.1:8000/
