FInd box on LAN

I think you'll need to know its IP address.

Bummer. How does a media player find a server? The pi is setup as a webserver. The Roku is set up to enter the I.P. manually now. Sure would be nice...

If you install some kind of UPnP software on the Pi that can respond to SSDP M-SEARCH requests, then I can post some code I have that discovers the IP addresses of other Rokus on the network that can easily be adapted to find your Pi(s) on the network.

Thank you. I'll look into making that happen and get back. Pi-world is pretty big, there must be something out there.

even easier - tell your router to always give the same IP to that MAC address, a feature often called "DHCP reservations"

Yes, well I do that at home, I want to make it more portable.

I want to write a roku function that will find a device on my LAN. It's a RaspberryPi,  which interestingly has the same first-half of the MAC address as all other pi's -B8:27:EB.

This will let you know why https://en.wikipedia.org/wiki/MAC_addre ... ss_details
Don't think you can use it though, there is no B/S API to query ARP cache.

What's the reason to want to know RasPi's IP from a Roku - are there particular services running on it?
If so, you might be able to discover that in a hacky way - say if there is web server, you can have some code that scans the network for your guy on port 80, knowing what to expect there.

As was inevitable, I've built a thing that is too complex, uses too much bandwidth, and is too artsy to be a screensaver so I've decided it's an installation. The Pi is a web server, holds all the files and does Imagemagick processing. So anything I can do to make it slicker while demonstrating it seems worth the effort. I think I will try belltown 's way first, but what you describe sounds like second choice for sure, If I get there I'll ask again about how I might go about that.

Thanks both of you for answering, I appreciate it.

Awesome, thank you.
