#2650 — Marina talks to herself

I'd never had the chance to setup to Apples both running Marina to see how
they fare until last evening. I used a platinum IIe with original Uthernet
talking to a standard (unenhanced) Apple IIe with the new Uthernet II. Both
were running a pre-release edition of Marina, but it's not much improved
since the January 2016 edition. The two cards were directly connected with
no intermediate hardware.

The two Uthernets seem to have negotiated a 10 Mb/s, half-duplex link,
judging from the status lights on the Uthernet II.

To my dismay, the Uthernet II seemed to be receiving its own broadcasts, so
the Marina instance running on that machine was mighty confused! It was
seeing its own ARP announcements and replying to them! This caught the
machine in an infinite loop.

Anyone else tried to do this? I'd love to run it through a switch or hub but
I don't have a good one handy for local testing.

I would greatly appreciate it if someone could setup two (or more, if
possible!) Apples running Marina on the same local net and see how they
behave with each other. If someone does plan on doing this, let me know, and
I'll modify the Marina demo to make it easier to send and receive messages
via UDP.

Meanwhile, I'm searching for a solution for the aforementioned problem, viz,
the Uthernet II receiving its own transmissions.

Hi David,
I can try during the week. I have a Uthernet I, Uthernet II alpha & Uthernet II release that I can plug into IIgs computers.
I hope Marina comes on bootable disks please!

Yes, but I should make a version for better testing.

Great. I'll make the changes and have it ready either later this week, or
next week. The next (presently unreleased) edition of Marina can reply to
pings; I should add the ability to send pings too. That'll be a good way to
test!
