HELP="
|
|
dns2omada.sh is the most simplistic script ever meant to paliate one of dumbest laziest lack of feature of the tp-link OMADA SDN software....
|
|
it simply populate the OMADA client's name based on DNS name... everytime the script runs it will keep a copy of the omada clients output
|
|
before and after the script execution in /var/tmp/omadaclients.*.dns2omada
|
|
|
|
using a python omada api...
|
|
Assumptions:
|
|
- you already have a local DNS server able to perform reverse DNS resolution per IP.
|
|
- you already have omada SDN setup on the network
|
|
- you should create an OMADA admin account dedicated to this process using a very long random password string without any special character
|
|
- my subnet is simply from 192.168.0.1 to 192.168.0.256 so I have a simple loop, you might have to modify the script if your subnet is class B
|
|
with an outer loop etc...
|
|
usage:
|
|
1) install python: sudo apt install python3-pip
|
|
2) install the omada python api: pip install tplink-omada-client
|
|
3) update the parameters CHANGE_ME values in the scipt below
|
|
4) run the script manually or in cron...
