Quoting https://osmud.org/ | How does MUD work? | | A MUD compliant network includes a MUD manager that communicates with | network services like DHCP allowing the MUD manager to be informed | of when devices enter and leave the network. Devices that provide | additional information and context about themselves via MUD specified | methods when seen on the network are considered to be ?MUD Enabled | Devices?. The MUD manager uses this context to obtain/download | information from the manufacturer defining allowed behaviors for | specific devices. The MUD manager uses the information (stored in a MUD | file) to communicate with network services including firewall, DNS, | and DHCP services and/or other services including network monitoring | software to communicate allowed behaviors of individual devices. And the MUD URL DHCP Option is documented at https://tools.ietf.org/html/draft-ietf-opsawg-mud-25#section-10 Sounds like a valid extension of dnsmasq. But I'm worn out. It took three attempts to get an answer what the original problem is. Hopefully there will be a fresh start like: | Hello, | | I am trying to set a DNSMASQ_MUD_URL variable from inside dnsmasq- giving | the script being called by dhcp-script access to that variable. | MUD is Manufacturer Usage Description ( https://osmud.org/ ) | | Find attached a patch with the extra source code. | | However, when it forks I am unable to follow the child process | in my debugger. I have tried setting "set follow-fork-mode <mode>" & | "set detach-on-fork <mode>" but after the process forks- it seems to | just hang and never be called. | | Also I've got my local variable inside the lease struct and passed to | queue_script() in helper.c. | | Any ideas how to debug the dhcp-script child process or where I should | set the environment variable to allow the script called by dhcp-script | to read this environment variable?
