NAME
ssh-import-id - retrieve one or more public keys from a public keyserver (Launchpad.net by default) and append them to the current user's authorized_keys file (or some other specified file) SYNOPSIS
ssh-import-id [options] USER_ID_1 [USER_ID_2] ... [USER_ID_n] OPTIONS
-h | --help usage -o | --output F write output to file 'F' (default ~/.ssh/authorized_keys, use "-" for standard out) DESCRIPTION
This utility will securely contact a public keyserver (https://launchpad.net by default) and retrieve one or more user's public keys, and append these to the current user's ~/.ssh/authorized_keys file. The system administrator can change the source URL used by ssh-import-id(1) by editing the configuration file, /etc/ssh/ssh_import_id, which is sourced to obtain the value of URL. By default, URL="https://launchpad.net/~%s/+sshkeys". Note that this url really MUST be a secure, https url with a valid, signed certificate or else your system will be vulnerable to man-in-the-middle attacks! The "%s" will be populated by ssh-import-id(1) with the value(s) of USER_ID_1 [USER_ID_2] ... [USER_ID_n]. SEE ALSO
