As CentOS 7 is getting to the end of it’s live it’s time to start thinking about an upgrade.
On my old server I tried LEAPP a couple of times (on a clone, of course), but success was not really guaranteed. So, a complete reinstall is in order.
But, as I move from CentOS 7 to Rocky Linux 9, this automatically means
some packages are no longer available. I was using sslh to connect
though SSH and HTTPS on port 443.
