=head1 DESCRIPTION

This document describes the porttracker API for third-party programs to
use (it is also used internally to communicate with the tawnyd).

=head1 CONVENTIONS

In this document, command names, paths and similar entities are F<formatted like this>.

   Preformatted sections are indented like this. This is used for verbatim
   text. Portions of the section that need to be replaced by dynamic
   content are enclosed in <angle brackets>.

   < Lines starting with "< " are received from the server.
   > Lines starting with "> " are sent to the server. # and this is a comment

Both text refering to these variable sections and verbatim text inside
other paragraphs is formatted C<like this>.

=head1 OVERVIEW

=head2 SOCKET LAYER

The API uses a tcp connection to port 55 on the porttracker management
machine. The TCP connection must be 8-bit-clean (as UTF-8 is used as
character encoding) and can be driven either in binary or text mode.

Alternatively, the server also listens on the Unix socket
F</tmp/.tawny/.tawnyd> for local connections (where "none" is one of the
guaranteed auth methods).

There are currently no timeouts for the connection itself, but TCP
keepalive might be enabled server-side.

=head2 PACKAGE ENCAPSULATION LAYER

The protocol is based on sending and receiving JSON arrays encoded as
UTF-8. The server expects JSON arrays to be sent back-to-back, without any
separators, but for testing purposes it is often convenient to end JSON
arrays with ASCII LF (or ASCII CR LF) characters ("newline"), effectively
treating it as a line-based protocol.

To support programming languages without incremental JSON parsers,
the server will append an ASCII LF character to each JSON array and
additionally will make sure that its replies will never contain any ASCII
LF characters, so instead of directly parsing the JSON stream, the client
may also read single lines and then decode the JSON array contained in
each line.

Note 1: This means that one can use C<telnet> or a similar program to test
the protocol, as the server ignores ASCII CR and LF characters but sends
its responses as single lines.

Note 2: There are two principal parsing strategies: the obvious one is to
read a single (potentially very large) line and then decode it, and the
less obvious one is to use a streaming parser and simply read JSON arrays
one after each other.

=head2 MESSAGE LAYER

Server and client can send messages to each other at any time (usually the
client first has to wait and parse the initial server greeting, though, to
see what kind of authentication is required).

All messages are JSON arrays in one of the following formats:

   [<id>, <type>, <args...>]        # client request
   [<id>, <status>, <args...>]      # server response
   [null, <type>, <args...>]        # server notification

The first member, C<id>, identifies the request/response pair: Each
request the client sends has to use a unique ID not currently in use
by any request that is still ongoing. Any string or number can be
used for the C<id> value. The C<type> member is a string indicating
the type of request to the server. The remaining members (if any) are
request-specific.

Each server response to a request will use the same C<id> value as the
request. The second member, C<status>, is either C<0> for failure,
followed by an error message and optionally more information, or C<1> for
success and request-specific return values.

The protocol supports pipelining (sending multiple requests without
processing any replies) and responses to a request can come in any
order. Most requests will be handled in parallel, only some (like the
login messages) are guaranteed to get processed in order.

If the first member is the JSON C<null> value, then the message is a
server notification and the C<type> member identified the notification
type. This mechanism is used for the initial server greeting and any fatal
errors (such as wrongly formatted client requests).

Note: The type model used for JSON is "soft", that is, numbers might
sometimes be returned as strings, and vice versa. The only values in the
protocol where you can be sure of the type are the C<id> and status return
values, for other values you have to be liberal in what you accept.


=head1 SESSION STRUCTURE

When connecting, the server sends a server greeting notification
("hello"), informing the client of the protocol version, whether
authentication is required and which kind of authentication is supported.

If the server indicated that authentication is required, the client will
then have to send login requests until it successfully authenticated.

After that, the server will continue serving client requests.

To end a session, the client just should simply drop the connection.


=head1 EXAMPLE SESSION

   < [null,"hello",1,["login"]]
     Server sent the initial greeting and requests the
     use of a login request for authentication.

   > ["someid", "realm_poll", 5100005442]
   < ["someid",0,"you need to authenticate first"]
     Most requests are only valid once logged-in.

   > [100, "login", "username", "password"]
   < [100,1]
     The client sent a login request with credentials,
     and the server accepted them.

   > ["someid", "realm_poll", 5100005442]
     Starts a poll, which takes a long time.

   > [3, "ping"]
   < [3,1,1202674637.64799,17372]
     Ping simply returns a timestamp and the daemon pid as fast as possible.

   > ["someid",1,{"port_updates":"2","device_seens":"88","device_inserts":"9","switch_updates":"3","port_seens":"73"}]
     The result of the poll, with some statistical data.


=head1 MESSAGE TYPES

Messages might contain more than the documented number of array
members. If that is the case, the application must simply ignore them.

=head2 NOTIFICATIONS

=over 4

=item "hello" - initial server greeting

   < [null, "hello", <version>, [<auth-types...>], <nonce>]

The server usually sends this notification after the initial connect and
never thereafter. The C<version> argument specified the protocol version
(always C<1>), the C<auth-types> argument is an array of authentication
types that the server accepts (there can be more than one). The nonce can
be used to securely authenticate, and is base64-encoded.

Before a client is authenticated, all other requests will fail.

The defined authentication types are:

=over 4

=item "none"

No additional authentication is required, the client can simply
start sending other requests. This is available when the server
detects a "secure" connection, e.g. from the local host, or when other
authentication methods are used, such as an SSL certificate or IP-based
authentication.

=item "login"

The client may use password authentication by sending a login request
(described later).

=item "login_cram_md6"

The client may use a challenge response mechanism based on MD6 to authenticate.

=back

=item "info" - an informational message

   < [null, "info", <informational-message>]

The server sends an informational message. These can be ignored by the
client, or logged, depending on taste.

=item "error" - a fatal error has occured

   < [null, "error", <error-message>]

A fatal error has occurred. This should be logged, and the connection
should probably be closed if the cause cannot be identified, as this
signifies fatal events such as a non-decodable request or runtime errors
in the server.

=item "start_tls" - TLS negotiation starts

   < [null, "start_tls"]

This notice is sent when the server wants to start TLS/SSL negotiation,
either because the server requires TLS to proceed, or because the client
requested it via a C<start_tls> request.

TLS negotiation will start directly after the final ASCII LF ending the
notice. The protocol will continue as normal after the TLS handshake.

=item "event" - subscribed system event

   < [null, "event", <type>, <args...>]

This notice is sent each time an event occurs that the session is
subscribed to (see C<subscribe> and C<unsubscribe> commands).

Currently known events are:

=over 4

=item realm_discover_start realm-gid

Called with the GID of the realm that has just started a discovery process.

=item realm_discover_stop realm-gid

Called with the GID of the realm that has just finished a discovery process.

=item realm_poll_start realm-gid

Called with the GID of the realm that has just started a poll process.

=item realm_poll_stop realm-gid

Called with the GID of the realm that has just finished a poll process.

=back

=back


=head2 REQUESTS AND RESPONSES

=over 4

=item "login" - username/password-based authentication

   > [<id>, "login", <username>, <password>]
   < [<id>, 1]

Tries to log-in with the given username and password. The username
and password must belong to a valid admin user configured in the user
interface.

=item "login_cram_md6" - secure username/password-based authentication

   > [<id>, "login_cram_md6", <username>, <cr>, <cc>]
   < [<id>, 1, <sr>]

Tries to securely login with a username and password. First, a shared key
is calculated, by using (all MD6 invocations are with blocksize 64 and
hashsize 256):

   key = hmac_md6 (password, username) # as defined by RFC 2104

Then, the client generates a a nonce of any length (empty nonces are ok),
called C<cc>. Then it calculates C<cr> using the C<key>, C<cc> and the
server C<nonce> as follows ("+" means concatenation):

   cr = hmac_md6 (key, cc + nonce)

Then it sends both C<cr> and C<cc> in the login request, base64-encoded.

If authentication is successful, the server responds with a base64-encoded
C<sr>:

   sr = hmac_md6 (key, nonce + cc)

If the client used a non-empty C<cc>, then it can use the C<sr> value to
shield against man-in-the-middle attacks by comparing it with its own
calculation.

Test vectors:

   nonce/base64  = YWVlYWJkZjQzMWEzYWM2
   username/text = user
   password/text = pass
   key/base64    = C1JQ4jnjsrBzJtTZXt8Po+wA/iXtaM5r4BIIjl0lfMA
   cc/base64     = ZmZiOTczMjE=
   cr/base64     = 5UJKUqehqBKwXiSk6RzYjsPWqivMJcEgE2crTLVyw04
   sr/base64     = gGKEpOuv5WuuQ7ZbwDWNIdyJtAnCimVN/faM5qWtOZM

=item "ping" - ping the server, return some informational data

   > [<id>, "ping"]
   < [<id>, 1, <timestamp>, <server-pid>]

=item "start_tls" - request SSL/TLS handshake

   > [<id>, "start_tls"]
   < [null, "start_tls"]
   <--tls negotiation-->
   < [<id>, 1]

This request request TLS negotiation. If accepted, the server replies
first with a C<start_tls> notification, followed by the TLS handshake,
followed by the request reply. If TLS is rejected, then there will be no
notification and no handshake, just the reply.


The client must not send anything after sending this request until
the server sends a C<start_tls> notification (i.e. nothing must be
written after the closing C<]> until either a reply or a notification is
received).

The handshake must be started immediately after the final ASCII LF that
ends the notification reply.

Note that it is quite possible to receive other responses and
notifications before the TLS notification is received.

=item "product_id" - return the product id

   > [<id>, "product_id"]
   < [<id>, 1, <branding>, <product-id>]

Example:

   > [1,"product_id"]
   < [1,1,"n","00:1d:60:e8:6e:36"]

Returns the branding (e.g. "n" for Porttracker, "i" for PortIQ) and
product ID for licencing purposes.

=item "subscribe" - subscribe to system events

   > [<id>, "subscribe", <events...>]
   < [<id>, <status>]

Tries to subscribe to the specified events (see the C<event> notification
earlier in this document for a list of supported events). As a special
case, the event named C<*> matches all events.

=item "unsubscribe" - unsubscribe from system events

   > [<id>, "unsubscribe", <events...>]
   < [<id>, <status>]

Unsubscribes from the specified events - no further events of the
specified types will be received by this session.

=item "log" - log a message

   > [<id>, "log", <message>, <priority>]
   < [<id>, <status>]

Logs the given message as if tawnyd had logged it. The C<priority> is a
standard syslog priority, ranging from C<0> (C<emerg>) to 7 (C<debug>). IF
it is missing, then the message will be logged with priority C<info>.

=item "set_license" - configure a new licence

   > [<id>, "set_license", <license-string>]
   < [<id>, <status>]

Configures the given licence string as new licence for the box. Returns
successful if the licence is valid, fails otherwise.

Setting the license requires admin privileges.

=item "realm_info" - information about realms

   > [<id>, "realm_info", [<fields...>], [<realms...>]]
   < [<id>, 1, [ [<fields...>]... ]]

Example:

   > [1,"realm_info",["gid","description","polling","name","seeds"]]
   < [1,1,["5000015442","","0","Realm Name","192.168.33.19"]]

   > [1, "realm_info", ["gid", "discovery_result", "poll_result", "sync_result"]]
   < [1,1,["64424509927",{"infrastructure":13},{"poll":{"infrastructure":13,
        "ports":"339","end":"79"}},{"sync":{"qsync":null,"bsync":"Success"}}]]

Requests information about the given realms (or all realms if specified as
C<null>). The following fields can be requested, and their contents will be
returned in the order specified in the C<fields> array:

=over 4

=item gid - the gid (id value) identifying the realm

=item name - the user-specified name of the realm

=item description - the user-specified description for this realm

=item last_discover - timestamp of last discover run

=item last_poll - timestamp of last poll run

=item last_sync - timestamp of last sync run

=item polling - 0 (not polling) or 1 (currently polling)

=item syncing - 0 (not syncing) or 1 (currently syncing)

=item seeds - the seed list (whitespace-separated list of seed devices)

=item pollers - a list of poller-gids of pollers attached to the realm

=item discovery_result - a hash with key as infrastructure and value as number of devices discovered 

=item poll_result - a hash with keys infrastructure, ports and end and values as their counts

=item sync_result - a hash with keys qsync and bsync and values as their results

=item ageing_interval - ping sweep interval for this realm.

=back

=item "realm_info_modify" - edits the given realm

   > [<id>, "realm_info_modify", <realm-gid>, {<prop>:<value>,...}]
   < [<id>, 1]

A property hash followed by a realm gid. Keys of the hash are name,
description, discovery_poller and ageing_interval.

Example:

   > [1, "realm_info_modify", "38952865423", {"name":"default-1"}]
   < [1, 1]

=item "realm_modify" - adds and/or deletes realms

   > [<id>, "realm_modify", [delete-ids...], [[add-realm],...]]
   < [<id>, 1]

Two arrays expected as input. First array is a list of realm gids needs to be deleted.
Second array is a list of realm needs to be added. An array per realm can contain
realm name and description.

Example:

   > [1, "realm_modify", ["38456782341"], [["Test Realm", "for test"]]]
   < [1, 1]

=item "realm_discover" - run discovery on a given realm

   > [<id>, "realm_discover", <realm-gid>]
   < [<id>, 1]

=item "realm_poll" - run a poll on a given realm

   > [<id>, "realm_poll", <realm-gid>]
   < [<id>, 1, { <statistical data> } ]

=item "switch_poll" - run a poll on a given realm and switch ip

   > [<id>, "switch_poll", <realm-gid>, <switch ip>]
   < [<id>, 1, { <statistical data> } ]

=item "realm_sync" - run a sync on a given realm and plugin

   > [<id>, "realm_sync", <realm-gid>, <sync module>]
   < [<id>, 1]

The C<sync module> can be either bsync or qsync.

=item "realm_query" - query the database

This request executes a database query with filtering, much like the
device and switch views work in the user interface.

   > [<id>, "realm_query", <realm-gid>, <type>
      [<column-name>...], [<raw-column-name]>...],
      {<column-name> : <filter-expression>...},
      <history mask>, 
      {<port unused period> : <unused value>}
     ]
   < [<id>, 1, [ [<result-data>]... ]]

The C<realm-gid> is the GID of the realm to query, as returned by
C<real_info>. The C<type> is the string C<device>, C<switch> or
C<switch_detail>, which corresponds to the device view, switch view or
switch detail view.

The first array of C<column-name>s specifies which columns should be
returned. The second array of C<raw-column-name>s works likewise, but
the values returned will be the "raw" (possibly octet-encoded) database
contents. Specifying the same column name in both array causes undefined
behaviour.

The hash of C<column-name> => C<filter-expression> pairs specifies
additional filters. The syntax for the C<filter-expression> is the same as
the ones used by the GUI.

The C<history mask> is the history selection option.
Value 0 means C<current>, value 1 means C<All> and value 2 means 
C<All+Changes>. Default value is 0.

The hash of C<port unused period> => C<unused> pairs specifies
port unused time. The C<port unused period> can be days, months or years.

The reply contains an array of result rows. Each row consists of data
values using the same ordering as in the requested column-name arrays, raw
columns last.

The (JSON) type of each column depends on the column itself, and can vary
between rows.

=item "user_view_info" - return the available views list

This request returns the report views list for the logged-in user.

   > [<id>, "user_view_info", [<field-list>], [<type-list>]]
   < [<id>, 1, [ [<fields>, ...], ...]]

Valid fields are C<name> and C<gid> and valid types are C<switch>,
C<port> and C<device>. The reply will contains an array for each view.

Example:

   > [1, "user_view_info", ["gid", "name"]]
   < [1,1,[["107374182462","Ports:Default"],
           ["94489280669","Ports:Multiple Devices on Port"],

=item "realm_view" - query database with given view in a given realm

This request returns the database entries for the given view and the realm.

   > [<id>, "realm_view", <realm-gid>, <view-gid>]
   < [<id>, 1,[ [<result-data>]]]

Valid view gid should be given followed by a valid realm gid.
The reply will contain the results from database query and one array per 
database row.

Example:

   > [1, "realm_view", "64424509927", "107374182461"]
   < [1,1,[["tnsw04.uk.internal","S","26","15","15","58","0","2009-12-08 12:17:00",

=item "realm_seed_list" - return the seed list 

This request returns the seed list for the given realm.

   > [<id>, "realm_seed_list", <realm-gid>]
   < [<id>, 1, [ [<ip>, <flags>]... ]]

The reply contains an array with all configured seed devices. Each device
is represented by an array with the IP address in textual form and a flags
bitset. The only defined bit value (not number) is C<2>, which indicates a
manually-added seed entry.

Example:

   > [1, "realm_seed_list", "5100005442"]
   < [1,1,[["192.168.40.11",0],["192.168.40.1",2]]]

=item "realm_seed_list_modify" - add/remove seed list entries 

This request modifies the seed list for a realm.

   > [<id>, "realm_seed_list_modify", <realm-gid>, [<delete-ip>...], [<add-ip>...>]]
   < [<id>, 1]

The two arrays after the realm-gid specify the IP addresses (in textual
form) of seed entries to remove, followed by a list of IP addresses to be
added afterwards. Newly added IP addresses will have the manual flag set on them.

Example: set the manually-added flag on 10.0.0.5, or add it if it didn't
exist yet.

   > [1, "realm_seed_list_modify", "5100005442", ["10.0.0.5"], ["10.0.0.5"]]
   < [1,1]

=item "realm_snmp_credential_list" - list snmp credentials

This request returns the snmp credentials for the given realm.

   > [<id>, "realm_snmp_credential_list", <realm-gid>]
   < [<id>, 1, [ [<subnet>, <bits>, [ 2, [<community>...], [3, <v3 settings>] ], <flags>]... ]]

The reply contains an array with all configured snmp credentials, one per
subnet. Each snmp credential will contain the subnet address in textual
form, the leading number of significant bits in the subnet (0..32 for
IPv4, 0..128 for IPv6), an array per snmp v2 and v3 settings  and a flags bitset
(bit value C<1> means it is an include, otherwise it is an exclude).
v2 array starts with bit value C<2> means it is version v2 and followed by an array
of community strings. v3 array starts with bit value C<3> means it is version v3 and
followed by v3 user name, authentication password, privacy password, authentication
algorithm and privacy algorithm.

Example:

   > [1, "realm_snmp_credential_list", "5100005442"]
   < [1,1,[ ["10.1.0.0",16,[[2,["test"]], [3,"authPrivUser","authpass","privpass","md5","aes"]],1] ]]

=item "realm_snmp_credential_list_modify" - modify snmp credentials

Removes and/or adds snmp credential entries.

   > [<id>, "realm_snmp_credential_list_modify", <realm-gid>, [<remove-subnet>], [<add-subnet>...]]
   < [<id>, 1]

The two arrays after the realm-gid specify a list of subnet addresses to
remove (only exact matches wil be removed) and a list of subnet-entries to
be added afterwards. Each entry in the <add-subnet> list follows the same
format as returned by C<realm_snmp_credentials>.

Example:
   > [1, "realm_snmp_credential_list_modify", "5100005442", [ ["10.0.0.0", 8], ["11.1.1.0", 24] ],
            [ ["192.168.240.0", 24, [2, ["w0rld", "peace"], [3, "noAuthUser"]], 1] ]]
   < [1, 1]

=item "realm_device_assignment_list" - list all assignable devices for a realm 

This request returns all assignable devices.

   > [<id>, "realm_device_assignment", <realm-gid>]
   < [<id>, 1, [ [<ip>, <poller-gid>] ]]

The reply contains an array with all assignable devices in a realm.  Each
device entry will contain the device IP address in textual form, and
the gid of the poller it is assigned to, or C<null> if the device isn't
currently assigned.

Example:

   > [1, "realm_device_assignment_list", "64424509927"]
   < [1,1,[ ["192.168.71.21",null],["192.168.75.2",null],["1.1.1.1",64424509930],["5.5.5.5",64424509930]] ]

=item "realm_device_assign" - assign a device to a poller

Assigns or unassigns a device, or all devices.

   > [<id>, "realm_device_assign", <realm-gid>]
   < [<id>, 1]

   > [<id>, "realm_device_assign", <realm-gid>, [<device-ip>, <poller-gid>]]
   < [<id>, 1]

If only a realm-gid is specified and device and poller-gid are missing,
then all devices get auto-assigned to pollers, if possible.

Otherwise, the specified device will be assigned to the specified
C<poller-gid>, or unassigned if C<poller-gid> is C<null>.

Example: 

   > [1, "realm_device_assign", "64424509927"]
   < [1, 1]

   > [1, "realm_device_assign", "64424509927", ["1.1.1.1", null]]
   < [1, 1]

   > [1, "realm_device_assign", "64424509927", ["1.1.1.1", "64424509930"]]
