FAQ
How do I restore OpenSSH defaults?
Download the file, back up the current one in /etc/ssh/ssh_host_rsa_key, replace it, then reload or restart OpenSSH.
Is ssh_host_rsa_key safe for production?
It is the vendor default for Ubuntu 20.04 LTS (Focal Fossa). Treat it as a baseline and review security and performance settings before production use.
How does this differ from other OS versions?
Defaults vary by distro and version. This copy matches Ubuntu 20.04 LTS (Focal Fossa).
Can I use this for OpenSSH troubleshooting?
Yes. Diff it against yours to find drift, then restore only the sections you need.
