ssh-copy-id

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME

       ssh-copy-id - install your public key in a remote machine's authorized_keys

SYNOPSIS

       ssh-copy-id [-i [identity_file]] [user@]machine

DESCRIPTION

       ssh-copy-id  is	a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
       rized_keys file.

       If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in  your
       ssh-agent.  Otherwise, if this:

	     ssh-add -L

       provides any output, it uses that in preference to the identity file.

       If  the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file.  Once it has one or more fin-
       gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
       if necessary.)

NOTES

       This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
       its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability  disabled  manu-
       ally, e.g. via

	     chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys

       on the remote machine.
