OK, I just added a new reason to why I chose JRiver, though I have to admit at the time I did not know this reason existed.
But, as of this afternoon, now I do.
Wake on LAN.
It was a surprise to me.
My desktop MC server had been shut down for maintenance reasons.
I was also working working on the MC client PC for those same maintenance reasons (a.k.a., Patch Tuesday).
I have the MC client PC version of Windows configured to boot into MC client and start up in theater mode.
But the MC server was powered down, or at least I thought it was. When I went to the desktop PC, I noticed it was booting up.
I knew I had enabled WoL for other reasons, so it was no surprise to me that it would boot up by itself.
What was the surprise, though not really a surprise, but more of a smiling recognition of what has been designed into MC. That the MC client sent a WoL packet to it's configured server.
Poking around in the Wiki, I found an entry that pointed to some decade+ old comments here.
So, succinctly, if the MC client is configured to connect to a MC server, and it sees no response from that server, it issues a network-based ~wake up-call~ to the server.
Excellent stuff, that is...
Thank-you to the developers.
