"Well-known port numbers are typically odd, because early systems using the port concept required an odd/even pair of ports for duplex operations. Most servers require only a single port. An exception is the BOOTP server which uses two: 67 and 68 (see BOOTstrap Protocol - BOOTP)." https://www.capesoft.com/Cached/UDP.htm

Old FTP also ran on a pair of ports: 21 and 20, as described here: https://en.m.wikipedia.org/wiki/File_Transfer_Protocol#Commu...

Are there any Old FTP servers still in existence? It would be neat to find one.

I miss those days. Maybe I'm just getting old, but it seems like a trend where time passing or more people getting involved in something causes its inherent quality/goodness/kindness to decrease. I accept that that's an illusion, though. Things aren't really getting worse overall, nor better. Nothing new under the sun.

Try to browse the web without an ad-blocker, then tell me things aren’t getting worse. I really don’t know how non-tech people can stand using the web. It’s almost a complete cesspool of ads, malware, alerts/notifications, shady sites, and dark patterns. Apps are winning the war because web sites owners make it impossible to use their site.

It's true--I never do this. And on the odd occasion when I get a new browser without adblock, I recoil in horror.

Same with broadcast and cable TV. Who watches this shit anymore?

Apparently IPsec, SSH, and SSL all appeared in 1995, as did SHA1 and 3DES, must have been quite a year for crypto. But those took time to catch on, especially as the systems were far more fragmented then than today. It took five years more to get rid of the si…

I did my junior (high-school) year English research paper on RSA and public key encryption that year (1995). I recall using a phrase along the lines of "This may lead to more trust of The Information Superhighway, and enable its use as a commercial trade center."

Curiously RSA is the one thing that's ancient, coming from the 70's. I don't know if it was used much at all for anything before mid nineties though.

Yeah, they'd done the math bit, but there wasn't really any practical application until Phil Zimmermann built and distributed (rather cleverly in some cases) PGP.
