Is that what you?re looking for? Thanks, Callum From: avahi <[email protected]> on behalf of "Shilliday, Peter" <[email protected]> Reply to: Avahi ML <[email protected]> Date: Tuesday, 28 April 2020 at 16:34 To: "[email protected]" <[email protected]> Subject: [avahi] Publishing Services on Specific Interfaces I am integrating avahi-client in a Linux application to publish a TCP-based service on two separate local networks, each on their own interface. Since the service uses the ephemeral TCP port range, the listening port on network #1 and network #2 will almost always be different, so I want to add the service on each network/interface individually as to publish the right port number. It appears avahi_entry_group_add_service() can take an interface index argument for this purpose; how can I look up the index for a given interface/network on my system?
