Well, that includes the Enterprise Linux major versions 8:

and 7:

Note that both - yes, even the latter, at least *this* one - are still 
under security fixes support:

> one# rpm -q openssh-server
> openssh-server-8.0p1-27.el8_10.x86_64

> other# rpm -q openssh-server
> openssh-server-7.4p1-23.0.3.el7_9.tuxcare.els3.x86_64

Whenever I want my hairSSH raised, I look at networking gear (switches 
etc.) instead - *not* over the Internet, of course. ;-)
