Update the known_hosts file. For each specified host, gpg will be -queried for a key associated with the host URI (see HOST URIs), -querying a keyserver if none is found in the user's keychain. search -for a gpg key for the host in the Web of Trust. If a key is found, it -will be added to the host_keys cache (see KEY CACHES) and any ssh keys -for the host will be removed from the user's known_hosts file. If the -found key is acceptable (see KEY ACCEPTABILITY), then the host's gpg -key will be added to the known_hosts file. If no gpg key is found for -the host, then nothing is done. If no hosts are specified, all hosts -listed in the known_hosts file will be processed. `k' may be used in -place of `update-known_hosts'. -.TP -.B update-userids [USERID]... -Add/update a userid in the authorized_user_ids file. The user IDs -specified should be exact matches to OpenPGP user IDs. For each -specified user ID, gpg will be queried for a key associated with that -user ID, querying a keyserver if none is found in the user's keychain. -If a key is found, it will be added to the user_keys cache (see KEY -CACHES) and the user ID will be added to the user's -authorized_user_ids file (if it wasn't already present). +queried for a key associated with the host URI (see HOST +IDENTIFICATION in +.BR monkeysphere(5)), +optionally querying a keyserver. +If an acceptable key is found for the host (see KEY ACCEPTABILITY in +.BR monkeysphere(5)), +the key is added to the user's known_hosts file. If a key is found +but is unacceptable for the host, any matching keys are removed from +the user's known_hosts file. If no gpg key is found for the host, +nothing is done. If no hosts are specified, all hosts listed in the +known_hosts file will be processed. This subcommand will exit with a +status of 0 if at least one acceptable key was found for a specified +host, 1 if no matching keys were found at all, and 2 if matching keys +were found but none were acceptable. `k' may be used in place of +`update-known_hosts'. .TP .B update-authorized_keys -Update the monkeysphere authorized_keys file. The monkeysphere -authorized_keys file will be regenerated from the valid keys in the -user_key cache, and the user's independently controlled -authorized_keys file (usually ~/.ssh/authorized_keys). +Update the authorized_keys file for the user executing the command +(see MONKEYSPHERE_AUTHORIZED_KEYS in ENVIRONMENT, below). First all +monkeysphere keys are cleared from the authorized_keys file. Then, or +each user ID in the user's authorized_user_ids file, gpg will be +queried for keys associated with that user ID, optionally querying a +keyserver. If an acceptable key is found (see KEY ACCEPTABILITY in +.BR monkeysphere (5)), +the key is added to the user's authorized_keys file. +If a key is found but is unacceptable for the user ID, any matching +keys are removed from the user's authorized_keys file. If no gpg key +is found for the user ID, nothing is done. This subcommand will exit +with a status of 0 if at least one acceptable key was found for a user +ID, 1 if no matching keys were found at all, and 2 if matching keys +were found but none were acceptable. `a' may be used in place of +`update-authorized_keys'. +.TP +.B gen-subkey [KEYID] +Generate an authentication subkey for a private key in your GnuPG +keyring. For the primary key with the specified key ID, generate a +subkey with "authentication" capability that can be used for +monkeysphere transactions. An expiration length can be specified with +the `-e' or `--expire' option (prompt otherwise). If no key ID is +specified, but only one key exists in the secret keyring, that key +will be used. `g' may be used in place of `gen-subkey'. .TP -.B gen-ae-subkey KEYID -Generate an `ae` capable subkey. For the primary key with the -specified key ID, generate a subkey with "authentication" and -"encryption" capability that can be used for MonkeySphere -transactions. +.B subkey-to-ssh-agent [ssh-add arguments] +Push all authentication-capable subkeys in your GnuPG secret keyring +into your running ssh-agent. Additional arguments are passed through +to +.BR ssh-add (1). +For example, to remove the authentication subkeys, pass an additional +`-d' argument. To require confirmation on each use of the key, pass +`-c'. `s' may be used in place of `subkey-to-ssh-agent'. .TP .B help Output a brief usage summary. `h' or `?' may be used in place of `help'. -.PD -.SH KEY ACCEPTABILITY -GPG keys are considered acceptable if the following criteria are met: -.PD + +.SH ENVIRONMENT + +The following environment variables will override those specified in +the monkeysphere.conf configuration file (defaults in parentheses): +.TP +MONKEYSPHERE_LOG_LEVEL +Set the log level.
