I'm using Ubuntu and I have a few keys which i'm using to connect to remote machines. The key I created using ssh-keygen -t rsa is located in my home folder at ~/.ssh/ and called rsa_id. I have another key which is being used by the DevOps team in my company and I want it to become the default key. I've looked at the file /etc/ssh/sshd_config and there's this line there:

HostKey /etc/ssh/ssh_host_rsa_key

So I was wondering about two things:

1. When I issue my key using the command specified above, does it copy the content of my newly created key to this file?
2. If I want to change the default key used, shall I add another `HostKey` line and point it to the DevOps key?

Thanks

  • You may be at risk of confusing the **system**'s key with the **user**'s key; the one in `/etc/ssh/ssh_host_rsa_key` identifies your system, not you as a user, and has nothing to do with `ssh`ing into remote systems. – MadHatter May 26 '14 at 07:48

Hi I believe this is the answer to your question. I did not want to copy paste the answer.
