nice, I like the amount of code we can save here.
One small thing regarding the ssh_version function, we are using the ssh client binary but it may be, that a system only has sshd installed.

sshd sadly does not have an option to print its version (you could run sshd with an invalid option to get the version, but this also throws an error).
