Print Usage summary -p port, -o ssh_option This option is useful if the server has restrictions on commands which can be used on the remote side. With this option the user's ~/.ssh/authorized_keys file will be downloaded, modified locally and uploaded with sftp. SFTP mode: usually the public keys are installed by executing commands on the remote side. Instead of installing keys on the remote system simply prints the key(s) that would have been installed. Of course, this can result in more than one copy of the key being installed on the remote system. This means that it does not need the private key. fįorced mode: doesn't check if the keys are present on the remote server.
Note that this can be used to ensure that the keys copied have the comment one prefers and/or extra options applied, by ensuring that the key file has these set as preferred before the copy is attempted. If the filename is omitted, the default_ID_file is used. Use only the key(s) contained in identity_file (rather than looking for identities via ssh-add(1) or in the default_ID_file). The options are as follows: -i identity_file It is also capable of detecting if the remote system is a NetScreen, and using its ‘ set ssh pka-dsa key. By default it adds the keys by appending them to the remote user's ~/.ssh/authorized_keys (creating the file, and directory, if necessary). It then assembles a list of those that failed to log in, and using ssh, enables logins with those keys on the remote server.
It assembles a list of one or more fingerprints (as described below) and tries to log in with each key, to see if any of them are already installed (of course, if you are not using ssh-agent(1) this may result in you being repeatedly prompted for pass-phrases).
#Ssh copy public key password
Ssh-copy-id is a script that uses ssh(1) to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities).
