ssh-import-id - retrieve one or more public keys from a public keyserver and append them to the current user’s authorized_keys file (or some other specified file)
ssh-import-id [options] USER_ID_1 [gh:USER_ID_2] ... [lp:USER_ID_n]
ssh-import-id-lp USER_ID_1 [USER_ID_2] ... [USER_ID_n]
ssh-import-id-gh USER_ID_1 [USER_ID_2] ... [USER_ID_n]
write output to file ’F’ (default
~/.ssh/authorized_keys, use "-" for standard out)
remove keys from authorized keys file ’F’
append U to the user agent string
Protocol can be ’lp’ for Launchpad.net, or ’gh’ for Github.com
This utility will securely contact a public keyserver and retrieve one or more user’s public keys, and append these to the current user’s ~/.ssh/authorized_keys file, standard output or any other specified output file.
User IDs can be prepended by a protocol:
- lp: to
- gh: to use https://api.github.com/users/%s/keys
If the protocol is not explicitly specified, then ssh-import-id will read a URL variable string from /etc/ssh/ssh_import_id as installed by your package manager and configured by your system administrator. You can override this locally by exporting the string you want in a URL environment variable. If all of these are empty, then the protocol is assumed to be "lp:", which was the original target implementation of this tool.
Any keys added will be "labled" with a trailing comment, "# ssh-import-id PROTO:USER_ID". Revoking keys will first look for lines in the authorized keys file ending with that label.
