ssh-import-id
ssh-import-id(1) ssh-import ssh-import-id(1)
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
ssh(1)
FILES
/etc/ssh/ssh_import_id
