Ssh-copy-id will handle the copy and setup of the key to a remote server in the proper way for you.
Your public key has been saved in /root /.ssh /id_rsa.pub. Your identification has been saved in /root /.ssh /id_rsa. Some times this will says like:Įnter file in which to save the key ( /root /.ssh /id_rsa ):Įnter passphrase (empty for no passphrase ): If you want to try alternate path, then you need to specify the same there. If default is fine, you can simply press enter. It is asking the path to save the key and default one is normally fine. In line “Enter file in which to save the key (/root/.ssh/id_rsa):” I am using default one here.Ĭouple of things to be taken care in the below output: For that you need to use “-b 4096” in the ssh-keygen command end. When we give ssh-keygen command, it will by default create a 2048 -bit RSA Key pair and if you need more stronger encryption you can use 4096 bit as well. To setup SSH keys between two servers we need to follow these steps: Step 1 : Create a Key Pair in the Source ServerĬreate a key pair on the source server.
Ssh copy id password#
Having your SSH keys setup can prevent the need for password to be entered manually for each task. There are numerous uses for SSH and the importance of SSH keys is when there is more repetitive process to be done in a short period like copying some files or folders, multiple users, multiple folders, multiple accounts, cpanel backups etc and in these cases it will be really boring and time consuming if you have to give ssh password each time it asks. You can move files, sync folders, migrate accounts and server files, copy backups etc. SSH is an important tool when it comes to a work to be done in another server.
