How to update the hostname of servers?

[mike-boost]

When running tctl nodes ls:
Only the Labels will update when the server's hostname is changed. The Host name is outdated.

I think the hostname is only read on startup. You'd likely need to restart or reload the Teleport process on the server to detect a change.

To change the hostname we need to change it in the node.
• sudo hostname “abc”
• sudo vi /etc/hostname ---> Change the hostname in this file
• vi /etc/teleport.yaml
Now reload teleport
• systemctl reload teleport
