Not unlike XMPP's > use of 5222 and 5223. Project Mercury ran from 1958 - 1963. Gemini uses port 1965 based on this same homage to the manned space programs leading up the the Apollo moon landing. More info on that here: https://en.wikipedia.org/wiki/Project_Mercury And since we're talking port numbers, that brings up another matter. Stephanie posted (or maybe I just read it on her page?) about a collision w/Tivoli on TCP 1965. She referred to it as a 'serious' conflict. No offense, but I don't see that as an issue at all. It's a non-privileged port and there are several instances where different types of services use the same ports with respect to UDP or TCP (even in /etc/services). I checked /etc/services on Debian Bullseye and Slackware -current just now and don't see port 1965 or Tivoli even mentioned. NOTE: This is not to say that it's not relevant or perhaps important to address, as Stephanie suggests. Here's something pertinent to that, as well as user accessibility: ```: A shitload of gobbledygook (noise) that prolly nobody wants to hear # From ``Assigned Numbers'': # #> The Registered Ports are not controlled by the IANA and on most systems #> can be used by ordinary user processes or programs executed by ordinary #> users. # #> Ports are used in the TCP [45,106] to name the ends of logical #> connections which carry long term conversations.

And as I pointed out in my immediately previous post, this isn't ASCII-art either. Remember folks, at this very moment in Gemini space, there are AT LEAST 113,310 pages of content, and that growth is logarithmic ;) I hope that helps :) Kindest regards, -- Bradley D.
