Apparently I installed that thing in 2006 and I last updated it in 2016, then I quit updating it for some reason that I totally forgot. Probably laziness...
It's been running for quite some time and we kind of forgot about it in the closet, until the SSH tunnel we use to get our mail outside our home stopped working because modern openssh clients refuse to use the antiquated key cipher I setup client machines with way back when any longer.
I just generated new keys with a more modern cipher that it understands (ecdsa-sha2-nistp256) and left it running. Because why not 🙂
Eh, plenty of dos machines still used in banks and industry. It’s both scary and impressive. I have worked on cnc machines only a few years back that were from the 80s I think. The data transfer between the computer and the machine used a band of paper that had holes punched into it by a printer like device physically attached to the computer.
Good old times.
