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
-e | --environment use the current environment (by default, all
environment variables are cleaned before importing ids)
-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].
The -e option will be necessary if you need to use a proxy defined in
$https_proxy, for instance.
