I'm having a router running OpenWrt and tinkering with it.
Udhcpc is the DHCP client running inside. I'm looking at /lib/netifd/proto/dhcp.sh (This script calls udhcpc).
My DHCP server has been configured to send option 150 (i.e TFTP server address) whenever a DHCP request comes in.
On the DHCP client, I would like to extract the TFTP server address once the DHCP ack is received on the router, and store it in a variable.
Can someone help me to understand what can be done in dhcp.sh about this?
