Any reason why port 1958 is chosen? I was thinking if it's adjacent to
Gemini (minus TLS) then why not something like 1964? Not unlike XMPP's
use of 5222 and 5223.
Project Mercury ran from 1958 - 1963. Gemini uses port 1965 based onthis same homage to the manned space programs leading up the the Apollomoon 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 acollision 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 anon-privileged port and there are several instances where differenttypes 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 justnow and don't see port 1965 or Tivoli even mentioned.
NOTE: This is not to say that it's not relevant or perhaps important toaddress, as Stephanie suggests.
Here's something pertinent to that, as well as user accessibility:

I dunno about anyone else here, but if I was blind, I sure as hellwouldn't want to listen to all of that. And as I pointed out in myimmediately previous post, this isn't ASCII-art either.
Remember folks, at this very moment in Gemini space, there are AT LEAST113,310 pages of content, and that growth is logarithmic ;)
I hope that helps :)
