NAME¶
msva-query-agent - query a Monkeysphere Validation Agent
SYNOPSIS¶
msva-query-agent CONTEXT PEER PKC_TYPE [PEER_TYPE] <
/path/to/public_key_carrier
ABSTRACT¶
msva-query-agent validates certificates for a given use by querying a running
Monkeysphere Validation Agent.
USAGE¶
msva-query-agent reads a certificate from standard input, and posts it to the
running Monkeysphere Validation Agent. The return code indicates the validity
(as determined by the agent) of the certificate for the specified purpose. The
agent's return message (if any) is emitted on stdout.
The first three command-line arguments are all required, supplied in order, as
follows:
- CONTEXT
- Context in which the certificate is being validated (e.g.
'https', 'ssh', 'ike')
- PEER
- The name of the intended peer. When validating a
certificate for a service, supply the host's full DNS name (e.g.
'foo.example.net')
- PKC_TYPE
- The format of public key carrier data provided on standard
input (e.g. 'x509der', 'x509pem', 'opensshpubkey', 'rfc4716')
The fourth argument is optional:
- PEER_TYPE
- The type of peer we are inquiring about (e.g. 'client',
'server')
RETURN CODE¶
If the certificate is valid for the requested peer in the given context, the
return code is 0. Otherwise, the return code is 1.
ENVIRONMENT VARIABLES¶
msva-query-agent's behavior is controlled by environment variables:
- MONKEYSPHERE_VALIDATION_AGENT_SOCKET
- Socket over which to query the validation agent. If unset,
the default value is 'http://127.0.0.1:8901'.
- MSVA_LOG_LEVEL
- Log messages about its operation to stderr. MSVA_LOG_LEVEL
controls its verbosity, and should be one of (in increasing verbosity):
silent, quiet, fatal, error, info, verbose, debug, debug1, debug2, debug3.
Default is 'error'.
COMMUNICATION PROTOCOL DETAILS¶
Communications with the Monkeysphere Validation Agent are in the form of JSON
requests over plain HTTP. Responses from the agent are also JSON objects. For
details on the structure of the requests and responses, please see
