SSH from older Linux versions to Alma Linux 9

Security
4

Some older versions of ssh only offer older keys. You can either put in $HOME/.ssh/config

<Hosname> (Or IP) 
HostKeyAlgorithms=ssh-dss

Or do it at command line with

ssh -oHostKeyAlgorithms=ssh-dss <target_name>

In either case it should be considered a temporary fix and ssh on target should
be upgraded as soon as possible.
