OpenSSH announces DSA-removal timeline

Apparently this particular unit is running OpenSSH 5.8, and current OpenSSH 9.x (at least as shipped by Fedora 38+) refuses to negotiate a session key [1] I haven't needed to get into this thing for the better part of a year, when I expanded one of the VLANs. I'm glad I found out about this problem now, when I have physical access to connect to the switch's serial console and no emergency going on.

[1] Can't negotiate a mutually perceptible host key algorithm. I _might_ be able to resolve this with a config change on the switch. But that requires being able to log in first.
