Linux Command of the Day

No fancy commands today, just good ol' functional admin action. I was setting up a couple of new Virtual Private Servers (ala EC2 or DamnVPS) and came across the following helpful command ssh-copy-id -i ~/.ssh/id\_rsa.pub username@remote\_server\_ip\_or\_domain What it does is copies (appends) your ssh key to the list of permissible keys on the remote server.

Need to make an SSH key for this purpose? ssh-keygen -t rsa -b 4096

Need to install ssh-copy-id on OSX? brew install ssh-copy-id
