ssh-copy-id - install your public key in a remote machine's authorized_keys
ssh-copy-id [-i [identity_file]] [user@]machine
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-
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:
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,
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.

SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for hostbased authentication
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
HostbasedAuthentication to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen-
Controls whether ssh-keysign is enabled.
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
authentication is used.
