We use separate wifi subnets for our mobile devices at different locations. All wifi locations have identical network settings (192.168.1.0/24). In order to determine the exact location, we would like to use the dhcp option 66 (TFTP server name) or option 67 (TFTP server address). the wifi subnets have only access to the locate LAN (individual IP settings).
I can activate this options over StageNow (DHCP Option Manager). But how do I get this information back? Can I read this values somewhere from a file? Is there a command to extract them?
