Preliminary operation instructions for rpkid et al.  These are the
production-side RPKI tools, for Internet Registries (RIRs, LIRs, etc).
See ../rcynic/README for relying party tools.

See INSTALLATION for how to install the software.

At present the package is intended to be run out of the scripts
directory.

In addition to the library routines in the scripts/rpki/ directory,
the package includes the following programs:

rpkid.py	The main RPKI engine daemon

rootd.py	A separate daemon for handling the root of an RPKI
		certificate tree.  This is essentially a stripped down
		version of rpkid with no SQL database, no left-right
		protocol implementation, and only the parent side of
		the up-down protocol.  It's separate because the root
		is a special case in several ways and it was simpler
		to keep the special cases out of the main daemon.

irdbd.py	A sample implementation of an IR database daemon.
		rpkid calls into this to perform lookups via the
		left-right protocol.

irbe-cli.py	A command-line client for the left-right control
		protocol. 

irbe-setup.py	An example of a script to set up the mappings between
		the IRDB and rpkid's own database, using the
		left-right control protocol.

cronjob.py	A trivial HTTP client used to drive rpkid cron events.

testbed.py	A test tool for running a collection of rpkid and irdb
		instances under common control, driven by a unified
		test script.

testpoke.py	A simple client for the up-down protocol, mostly
		compatable with APNIC's rpki_poke.pl tool.

Most of these programs take configuration files in a common format
similar to that used by the OpenSSL command line tool.  The test
programs also take input in YAML format to drive the tests.  Runs of
the testbed.py test tool will generate a fairly complete set
configuration files which may be useful as examples.

Basic operation consists of creating the appropriate MySQL databases,
starting rpkid, rootd, and irdbd, using the left-right control
protocol to set up rpkid's internal state, and setting up a cron job
to invoke rpkid's cron action at regular intervals.  All other
operations should occur either as a result of cron events or as a
result of incoming left-right and up-down protocol requests.

Note that the publication protocol isn't fully specified yet, much
less implmenented.  At the moment rpkid just writes its outputs to a
local directory tree.

Note that the full event-driven model for rpkid hasn't yet been
implemented.  The design is intended to allow an arbitrary number of
hosted RPKI engines to run in a single rpkid instance, but without the
event-driven tasking model one has to set up a separate rpkid instance
for each hosted RPKI engine.

At present the daemon programs all run in foreground, that is, if one
wants them to run in background one must do so manually, eg, using
Bourne shell syntax:

  $ python whatever.py &
  $ echo >whatever.pid  "$!"

All of the daemons use syslog.  At present they all set LOG_PERROR, so
all logging also goes to stderr.

----------------------------------------------------------------

rpkid.py:

rpkid is the main RPKI engine daemon.  Configuration of rpkid is a two
step process: a config file to bootstrap rpkid to the point where it
can speak using the left-right protocol, followed by dynamic
configuration via the left-right protocol.  In production use the
latter stage would be handled by the IRBE stub; for test and
develoment purposes it's handled by the irbe-cli.py command line
interface or by the testbed.py test framework.

rpkid stores dynamic data in an SQL database, which must have been
created for it, as explained in the installation guide.

The default config file is rpkid.conf, start rpkid with "-c filename"
to choose a different config file.  All options are in the section
"[rpkid]".  Certificates, keys, and trust anchors may be in either DER
or PEM format.

Config file options:

startup-message:	String to log on startup, useful when
			debugging a collection of rpkid instances at
			once.

sql-username:		Username to hand to MySQL when connecting to
			rpkid's database.

sql-database:		MySQL's database name for rpkid's database.

sql-password:		Password to hand to MySQL when connecting to
			rpkid's database.

cms-ta-irdb:		Name of file containing CMS trust anchor to
			use when authenticating messages from irdbd.

cms-ta-irbe:		Name of file containing CMS trust anchor to
			use when authenticating control messages from
			IRBE.

cms-key:		Name of file containing RSA key to use when
			signing CMS messages to IRBE or irdbd.

cms-certs:		Name(s) of file(s) containing certificate(s)
			to include in CMS wrapper when signing
			messages to IRBE or irdbd.   You can specify
			more than one certificate using OpenSSL-style
			subscripts: cms-certs.0, cms-certs.1, etc.

https-key:		Name of file containing RSA key to use, both
			in the HTTPS server role (for both up-down and
			left-right protocols) and in the HTTPS client
			role (left-right protocol only).

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in same contexts where https-key is
			used.  You can specify more than one
			certificate using OpenSSL-style subscripts:

			when verifying irdbd's HTTPS server
			certificate.

irdb-url:		Service URL for irdbd.  Must be a https:// URL.

https-server-host:	Hostname or IP address on which to listen for
			HTTPS connections.  Current default is
			INADDR_ANY (IPv4 0.0.0.0); this will need to
			be hacked to support IPv6 for production.

https-server-port:	TCP port on which to listen for HTTPS
			connections.

publication-kludge-base: [TEMPORARY] Local directory under which
			generated certificates etc should be
			published.  This is a temporary expedient
			until the publication protocol is defined and
			implemented.  Default is "publication/"

----------------------------------------------------------------

rootd.py:

rootd is a stripped down implmenetation of (only) the server side of
the up-down protocol.  It's a separate program because the root
certificate of an RPKI certificate tree requires special handling and
may also require a special handling policy.  rootd is a simple
implementation intended for test use, it's not suitable for use in a
production system.  All configuration comes via the config file.

The default config file is rootd.conf, start rootd with "-c filename"
to choose a different config file.  All options are in the section
"[rootd]".  Certificates, keys, and trust anchors may be in either DER
or PEM format.

Config file options:

cms-ta:			Name of file containing trust anchor to use
			when verifying CMS up-down queries.

cms-key:		Name of file containing RSA key to use when
			signing CMS up-down replies.

cms-certs:		Name(s) of file(s) containing certificate(s)
			to include in CMS wrapper when signing up-down
			replies.   You can specify more than one
			certificate using OpenSSL-style subscripts:
			cms-certs.0, cms-certs.1, etc.

https-key:		Name of file containing RSA key to use in the
			HTTPS server role for the up-down protocol.

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in the HTTPS server role for the
			up-down protocol.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: https-certs.0, https-certs.1,
			etc.

https-server-host:	Hostname or IP address on which to listen for
			HTTPS connections.  Default is localhost.

https-server-port:	TCP port on which to listen for HTTPS
			connections.

rpki-key:		Name of file containing RSA key to use in
			signing resource certificates.

rpki-issuer:		Name of file containing self-signed root
			resource certificate corresponding to
			rpki-key.

rpki-subject-filename:	Name of file that rootd should use to save the
			one and only certificate it issues.

rpki-pkcs10-filename:	Name of file that rootd should use when saving
			a copy of the received PKCS #10 request for a
			resource certificate.  This is only used for
			debugging.  Default is not to save the PKCS
			#10 request.

----------------------------------------------------------------

irdbd.py:

irdbd is a sample implemntation of the server side of the IRDB
callback subset of the left-right protocol.  In production use this
service is a function of the IRBE stub; irdbd may be suitable for
production use in simple cases, but an IR with a complex IRDB may need
to extend or rewrite irdbd.

irdbd requires a pre-populated database to represent the IR's
customers.  irdbd expects this database to use the SQL schema defined
in docs/sample-irdb.sql.  Once this database has been populated, the
IRBE stub needs to create the appropriate objects in rpkid's database
via the control subset of the left-right protocol, and store the
linkage IDs (foreign keys into rpkid's database, basicly) in the
IRDB.  The irbe-setup.py program shows an example of how to do this.

irdbd's default config file is irdbd.conf, start irdbd with "-c
filename" to choose a different config file.  All options are in the
section "[irdbd]".  Certificates, keys, and trust anchors may be in
either DER or PEM format.

Config file options:

startup-message:	String to log on startup, useful when
			debugging a collection of irdbd instances at
			once.

sql-username:		Username to hand to MySQL when connecting to
			irdbd's database.

sql-database:		MySQL's database name for irdbd's database.

sql-password:		Password to hand to MySQL when connecting to
			irdbd's database.

cms-ta:			Name of file containing CMS trust anchor to
			use when authenticating messages from rpkid.

cms-key:		Name of file containing RSA key to use when
			signing CMS messages to rpkid.

cms-certs:		Name(s) of file(s) containing certificate(s)
			to include in CMS wrapper when signing
			messages to rpkid.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: cms-certs.0, cms-certs.1, etc.

https-key:		Name of file containing RSA key to use in the
			HTTPS server role when listening for
			connections from rpkid. 

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in the HTTPS server role when listening
			for connections from rpkid.  You can specify
			more than one certificate using OpenSSL-style
			subscripts: https-certs.0, https-certs.1, etc.

https-url:		Service URL for irdbd.  Must be a https:// URL.

----------------------------------------------------------------

irbe-cli.py:

irbe-cli is a simple command line client for the control subset of the
left-right protocol.  In production use this functionality would be
part of the IRBE stub.

Basic configuration of irbe-cli is handled via a config file.  The
specific action or actions to be performed are specified on the
command line, and map closely to the left-right protocol itself.

At present the user is assumed to be able to read the (XML) left-right
protocol messages, and with one exception, no attempt is made to
interpret the responses other than to check for errors.  The one
exception is that, if the --pem_out option is specified on the command
line, any PKCS #10 requests received from rpkid will be written in PEM
format to that file; this makes it easier to hand these requests off
to the business PKI in order to issue signing certs corresponding to
newly generated business keys.

Usage: irbe-cli.py --config= --help --pem_out=

  parent	--action= --type= --tag= --self_id= --parent_id=
		--bsc_id= --repository_id= --peer_contact_uri=
		--sia_base= --sender_name= --recipient_name=
		--cms_ta= --https_ta= --rekey --reissue --revoke

  repository	--action= --type= --tag= --self_id= --repository_id=
		--bsc_id= --peer_contact_uri= --cms_ta= --https_ta= 

  self		--action= --type= --tag= --self_id= --crl_interval=
		--extension_preference= --rekey --reissue --revoke
		 --run_now --publish_world_now
		 --clear_extension_preferences

  child		--action= --type= --tag= --self_id= --child_id=
		--bsc_id= --cms_ta= --reissue

  route_origin	--action= --type= --tag= --self_id= --route_origin_id=
		 --as_number= --ipv4= --ipv6= --suppress_publication

  bsc		--action= --type= --tag= --self_id= --bsc_id=
		--key_type= --hash_alg= --key_length= --signing_cert=
		--generate_keypair --clear_signing_certs

Global options (--config, --help, --pem_out) come first, then zero or
more commands (parent, repository, self, child, route_origin, bsc),
each followed by its own set of options.   The commands map to
elements in the left-right protocol, and the command-specific options
map to attributes or subelements for those commands.

--action is one of create, set, get, list, or destroy; exactly one of
these must be specified for each command.

--type is query or reply; since irbe-cli is a client, query is the
default. 

--tag is an optional arbitrary tag (think IMAP) to simplify matching
up replies with batched queries.

--*_id options refer to the primary keys of previously created
objects.

The remaining options are specific to the particular commands, and
follow directly from the left-right protocol specification.

A trailing "=" in the above option summary indicates that an option
takes a value, eg, "--action create" or "--action=create".  Options
without a trailing "=" correspond to boolean control attributes.

The default config file for irbe-cli is irbe.conf, start rpkid with
"-c filename" (or "--config filename") to choose a different config
file.  All options are in the section "[irbe-cli]".  Certificates,
keys, and trust anchors may be in either DER or PEM format.

Config file options:

cms-ta:			Name of file containing CMS trust anchor to
			use when authenticating messages from rpkid.

cms-key:		Name of file containing RSA key to use when
			signing CMS messages to rpkid.

cms-certs:		Name(s) of file(s) containing certificate(s)
			to include in CMS wrapper when signing
			messages to rpkid.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: cms-certs.0, cms-certs.1, etc.

https-key:		Name of file containing RSA key to use in the
			HTTPS client role when contacting rpkid. 

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in the HTTPS client role when
			contacting rpkid.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: https-certs.0, https-certs.1,
			etc.

https-ta:		Name of file containing trust anchor to use
			when verifying rpkid's HTTPS server
			certificate.

https-url:		Service URL for rpkid.  Must be a https:// URL.

----------------------------------------------------------------

irbe-setup.py config file:

The default config file is irbe.conf, start rpkid with "-c filename"
to choose a different config file.  Most options are in the section
"[irbe-cli]", but a few are in the section "[irdbd]".  Certificates,
keys, and trust anchors may be in either DER or PEM format.

Options in the "[irbe-cli]" section:

cms-ta:			Name of file containing CMS trust anchor to
			use when authenticating messages from rpkid.

cms-key:		Name of file containing RSA key to use when
			signing CMS messages to rpkid.

cms-certs:		Name(s) of file(s) containing certificate(s)
			to include in CMS wrapper when signing
			messages to rpkid.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: cms-certs.0, cms-certs.1, etc.

https-key:		Name of file containing RSA key to use in the
			HTTPS client role when contacting rpkid. 

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in the HTTPS client role when
			contacting rpkid.  You can specify more than
			one certificate using OpenSSL-style

			irdbd's database.

sql-database:		MySQL's database name for irdbd's database.

sql-password:		Password to hand to MySQL when connecting to
			irdbd's database.

----------------------------------------------------------------

cronjob.py:

This is a trivial program to trigger a cron run within rpkid.  Once
rpkid has been converted to the planned event-driven model, this
function will be handled internally, but for now it has to be
triggered by an external program.  For pseudo-production use one would
run this program under the system cron daemon.  For scripted testing
it happens to be useful to be able to control when cron cycles occur,
so at the current stage of code development use of an external trigger
is a useful feature.

The default config file is cronjob.conf, start cronjob with "-c
filename" to choose a different config file.  All options are in the
section "[cronjob]".  Certificates, keys, and trust anchors may be in
either DER or PEM format.

Config file options:

https-key:		Name of file containing RSA key to use in the
			HTTPS client role when contacting rpkid. 

https-certs:		Name(s) of file(s) containing certificate(s)
			to use in the HTTPS client role when
			contacting rpkid.  You can specify more than
			one certificate using OpenSSL-style
			subscripts: https-certs.0, https-certs.1,
			etc.

https-ta:		Name of file containing trust anchor to use
			when verifying rpkid's HTTPS server
			certificate.

https-url:		Service URL for rpkid.  Must be a https:// URL.

----------------------------------------------------------------

testbed.py:

testbed is a test harness to set up and run a collection of rpkid and
irdbd instances under scripted control.  testbed is a very recent
addition to the toolset and is still evolving rapidly.

Unlike the programs described above, testbed takes two configuration
files in different languages.  The first configuration file uses the
same syntax as the above configuration files but is completely
optional.  The second configuration file is the test script, which is
encoded using the YAML serialization language (see
http://www.yaml.org/ for more information on YAML).  The YAML script
is not optional, as it describes the test layout.  testbed is designed
to support running a fairly wide set of test configurations as canned
scripts without writing any new control code.  The intent is to make
it possible to write meaningful regression tests.

All of the options in in the first (optional) configuration file are
just overrides for wired-in default values.   In most cases the
defaults will suffice, and the set of options is still in flux, so
only a few of the options are described here.    The default name for
this configuration file is testbed.conf, run testbed with "-c
filename" to change it.

testbed.conf options:

testbed_dir:	Working directory into which testbed should write the
		(many) files it generates.  Default is "testbed.dir".

irdb_db_pass:	MySQL password for the "irdb" user.  Default is
		"fnord".  You may want to override this.

rpki_db_pass:	MySQL password for the "rpki" user.  Default is
		"fnord".  You may want to override this.

rootd_sia:	rsync URI naming a (perhaps fictious) directory to use
		as the id-ad-caRepository SIA value in the generated
		root resource certificate.  Default is
		"rsync://wombat.invalid/".  You may want to override
		this if you intend to run an rsync server and test
		against the generated results using rcynic.   This
		default will likely change if and when testbed learns
		how to run rcynic itself as part of the test suite.

The second configuration file is named testbed.yaml by default, run
testbed with "-y filename" to change it.  The YAML file contains
multiple YAML "documents".  The first document describes the initial
test layout and resource allocations, subsequent documents describe
modifications to the initial allocations and other parameters.
Resources listed in the initial layout are aggregated automatically,
so that a node in the resource hierarchy automatically receives the
resources it needs to issue whatever its children are listed as
holding.  Actions in the subsequent documents are modifications to the
current resource set, modifications to validity dates or other
non-resource parameters, or special commands like "sleep".  The
details are still evolving, but here's an example of current usage:

    name:           RIR
    #valid_until:   2008-07-14T12:30:00Z
    valid_for:      2d
    sia_base:       "rsync://wombat.invalid/"
    kids:
      - name: LIR0
	kids:
	  - name: Alice
	    ipv4: 192.0.2.1-192.0.2.33
	    asn:  64533
    ---
    - name: Alice
      valid_add:   10
    ---
    - name: Alice
      add_as: 33
      valid_add:   2d
    # valid_until: 2009-07-14T12:30:00Z
    ---
    - name: Alice
    # valid_until: 2009-04-01T00:00:00Z
      valid_sub:   2d
    ---
    - name: Alice
    # valid_until: 2009-04-01T00:00:00Z
      valid_for:   10d

This specifies an initial layout consisting of an RPKI engine named
"RIR", with one child "LIR0", which in turn has one child "Alice".
Alice has a set of assigned resources, and all resources in the system
are initially set to be valid for two days from the time at which the
test is started.  The first subsequent document adds ten seconds to
the validity interval for Alice's resources and makes no other
modifications.  The second subsequent document grants Alice additional
resources and adds another two days to the validity interval for
Alice's resources.  The next document subtracts two days from the
validity interval for Alice's resources.  The final document sets the
validity interval for Alice's resources to ten days.

Operators in subsequent (update) documents:

  add_as, add_v4, add_v6:	These add ASN, IPv4, or IPv6
				resources, respectively.

  sub_as, sub_v4, sub_v6:	These subtract resources.

  valid_until:			Set an absolute expiration date.

  valid_for:			Set a relative expiration date.

  valid_add, valid_sub:		Add to or subtract from validity interval.

  sleep [interval]:		Sleep for specified interval, or until
				testbed receives a SIGALRM signal.

Absolute timestamps should be in the form shown (UTC timestamp format
as used in XML).

Intervals (valid_add, valid_sub, valid_for, sleep) are either
integers, in which case they're interpreted as seconds, or are a
string of the form "wD xH yM zS" where w, x, y, and z are integers and
D, H, M, and S indicate days, hours, minutes, and seconds.  In the
latter case all of the fields are optional, but at least one must be
specified.  For example, "3D4H" means "three days plus four hours".

testpoke.py:

This is a command-line client for the up-down protocol.  Unlike all of
the above programs, testpoke does not accept a config file in
OpenSSL-compatable format at all.  Instead, it is configured
exclusively by a YAML script.  testpoke's design was constrained by a
desire to have it be compatable with APNIC's rpki_poke.pl tool, so
that the two tools could use a common configuration language to
simplify scripted testing.  There are minor variations due to slightly
different feature sets, but YAML files intended for one program will
usually work with the other.

README for APNIC's tool describing the input language can be found at
http://mirin.apnic.net/svn/rpki_engine/branches/gary-poker/client/poke/README

testpoke.py takes a simplified command line and uses only one YAML
input file.

Usage: python testpoke.py [ { -y | --yaml }    configfile ]
                          [ { -r | --request } requestname ]
			  [ { -h | --help } ]

Default configuration file is testpoke.yaml, override with --yaml
option.

The --request option specifies the specific command within the YAML
file to execute.   

Sample configuration file:

    ---
    # $Id$

    version: 1
    posturl: https://localhost:4433/up-down/1
    recipient-id: wombat
    sender-id: "1"

    ssl-cert-file: biz-certs/Frank-EE.cer
    ssl-key-file: biz-certs/Frank-EE.key
    ssl-ca-cert-file: biz-certs/Bob-Root.cer

    requests:
      list:
	type: list
      issue:

      revoke:
	type: revoke
	class: 1
	ski: "CB5K6APY-4KcGAW9jaK_cVPXKX0"

testpoke adds one extension to the language described in APNIC's
README: the cms-cert-chain-* and ssl-cert-chain-* options, which allow
one to specify a chain of intermediate certificates to be presented in
the CMS or TLS protocol.  APNIC's initial implementation required
direct knowledge of the issuing certificate (ie, it supported a
maximum chain length of one); subsequent APNIC code changes have
probably relaxed this restriction, and with luck APNIC has copied
testpoke's syntax to express chains of intermediate certificates.
