I use
ssh-copy-id "-p $SERVERPORT -i /home/$USERNAME/.ssh/vpn-server.key.pub $SERVERUSERNAME@$SERVERIPV4"
or
ssh-copy-id -i /home/$USERNAME/.ssh/vpn-server.key.pub "-p $SERVERPORT $SERVERUSERNAME@$SERVERIPV4"is not correct
ssh-copy-id -i /home/$USERNAME/.ssh/vpn-server.key.pub $SERVERUSERNAME@$SERVERIPV4so you can run
Thank you.
see ssh-copy-id 's man manual:
SSH-COPY-ID(1) BSD General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id use locally available keys to authorise logins on a remote machine
SYNOPSIS
ssh-copy-id [-f] [-n] [-i [identity_file]] [-p port] [-o ssh_option] [user@]hostname
ssh-copy-id -h | -? however, I remember that the ssh-copy-id of centos 6 and ubuntu 12.04 does not support port parameters. I saw its source code (pure shell script) at that time, but there was no resolution of port parameters. At that time, I remember that I had hack its source code, and I added the port parameter to achieve this requirement. So there's still some impression here. Later higher versions of ssh-copy-id append the port parameter to specify the SSH port number. If your ssh-copy-id does not support the specified port number, you can only manually append your public key to the ~ / .ssh/authorized_keys of the remote server.
in fact, this is how the source code of ssh-copy-id is written
ssh-copy-id -p modify Port to your port number
