CONDOR_TOKEN_FETCH(1)

NAME
condor_token_fetch - HTCondor Manual

obtain a token from a remote daemon for the IDTOKENS authentication method

SYNOPSIS

condor_token_fetch [-authz authz ...] [-lifetime value] [-pool pool_name] [-name hostname] [-type type] [-token filename | -file filename] [-key signing_key]

condor_token_fetch [-help ]

DESCRIPTION

condor_token_fetch will attempt to fetch an authentication token from a remote daemon. If successful, the identity embedded in the token will be the same as client's identity at the remote daemon.

Authentication tokens are a useful mechanism to limit an identity's authorization or to establish an alternate authentication method. For example, an administrator may utilize condor_token_fetch to create a token for a monitoring host that is limited to only the READ authorization. A user may use condor_token_fetch while they are logged in to a submit host then use the resulting token to submit remotely from their personal laptop.

If the -lifetime or (one or more) -authz options are specified, the token will contain additional restrictions that limit what the client will be authorized to do.

By default, condor_token_fetch will query the local condor_schedd; by specifying a combination of -pool, -name, or -type, the tool can request tokens in other pools, on other hosts, or different daemon types.

If successful, the resulting token will be sent to stdout. With the -token option, the token will instead be written to the user's token directory (the value may not have any path information). With the -file option, the token will be written to the given file (the value may be an arbitrary filename).

OPTIONS

-authz authz
    Adds a restriction to the token so it is only valid to be used for a given authorization level (such as READ, WRITE, DAEMON, ADVERTISE_STARTD). If multiple authorizations are needed, then -authz must be specified multiple times. If -authz is not specified, no authorization restrictions are added and authorization will be solely based on the token's identity. NOTE that -authz cannot be used to give an identity additional permissions at the remote host. If the server's admin only permits the user READ authorization, then specifying -authz WRITE in a token will not allow the user to perform writes.

-debug
    Causes debugging information to be sent to stderr, based on the value of the configuration variable TOOL_DEBUG.

-help
    Display brief usage information and exit.

-lifetime value
    Specify the lifetime, in seconds, for the token to be valid (the token validity will start when the token is signed). After the lifetime expires, the token cannot be used for authentication. If not specified, the token will contain no lifetime restrictions.

-name hostname
    Request a token from the daemon named hostname in the pool. If not specified, the locally-running daemons will be used.

-pool pool_name
    Request a token from a daemon in a non-default pool pool_name.

-token filename
    Specifies a filename, relative to the directory in the SEC_TOKEN_DIRECTORY configuration variable (defaulting to ~/.condor/tokens.d), where the resulting token is stored. If not specified, the token will be sent to stdout.

-type type
    Request a token from a specific daemon type type. If not given, a condor_schedd is used.

-key signing_key
    Request a token signed by the signing key named signing_key. If not given, the daemon's default key will be used.

EXAMPLES

To obtain a token with a lifetime of 10 minutes from the default condor_schedd:

$ condor_token_fetch -lifetime 600
eyJhbGciOiJIUzI1NiIsImtpZCI6IlBPT0wifQ.eyJpYX...ii7lAfCA

To request a token from bird.cs.wisc.edu which is limited to READ and WRITE:

$ condor_token_fetch -name bird.cs.wisc.edu \
                      -authz READ -authz WRITE
eyJhbGciOiJIUzI1NiIsImtpZCI6IlBPT0wifQ.eyJpYX...lJTj54

To create a token from the collector in the htcondor.cs.wisc.edu pool and then to save it to ~/.condor/tokens.d/friend:

$ condor_token_fetch -identity friend@cs.wisc.edu -lifetime 600 -token friend

EXIT STATUS

condor_token_fetch will exit with a non-zero status value if it fails to request or read the token. Otherwise, it will exit 0.
