Version: TOC1.0
This document describes the protocol between TOC and TOC clients.
The protocol is built on TCP. Framing is done by SFLAP,
described at the bottom of this document. Inside each
SFLAP frame is a TOC command.
The TOC protocol is ASCII based, and special attention
must be placed argument separation. The separator and
the rules of separation are different for messages inbound
to TOC and outbound to the client. The rules of separation
are described in sections below.
The TOC server is built mainly to service the TIC and TiK clients. Since
the TIC client is a Java applet, and downloadable, TOC will NOT support
multiple TOC protocol versions at the same time. Therefore, TiK
users will be forced to upgrade if the protocol version changes.
TOC sends down the protocol version it expects the client
to speak and understand. Note, the protocol version is a string.
Important Notes
===============
* TOC will drop the connection if a command exceeds the maximum
length, which is currently 2048 bytes. So the client needs to
spend special attention to im, chat, and config message lengths.
There is an 8k length maximum from TOC to the client.
* No commands should be sent to TOC (besides toc_signon) before
a SIGN_ON is received. If you do send a command before SIGN_ON
the command will be ignored, and in some case the connection
will be dropped.
* Initial permit/deny items should be sent after receiving SIGN_ON
but before sending toc_init_done, otherwise the user will flash
on peoples buddylist who the user has denied. You will probably
want to send the toc_add_buddies at this time also.
* After TOC sends the PAUSE message to a client, all messages sent
to TOC will be ignored, and in some cases the connection will
be dropped. Another SIGN_ON message will be sent to the client
when it is online again. The buddy list and permit/deny items must
be sent again, followed by the toc_init_done. In most cases the
SIGN_ON message will be sent between 1-2 seconds after the
PAUSE message. Therefore a client could choose to ignore the
PAUSE message and hope nothing bad happens.
Client -> TOC
==============
The commands and the arguments are usually separated by whitespaces. Arguments
with whitespace characters should be enclosed in quotes. Dollar signs,
curly brackets, square brackets, parentheses, quotes, and backslashes
must all be backslashed whether in quotes or not. It is usually
a good idea just to use quotes no matter what. All user names from clients
to TOC should be normalized (spaces removed and lowercased), and therefore
are the one exception to the always use quotes rule.
When sending commands to the server you will not get a response
back confirming that the command format was correct or not! However
in some cases if the command format was incorrect the connection
will be dropped.
RoastingString="Tic/Toc"
toc_signon <authorizer host> <authorizer port> <User Name> <Password>
<language> <version>
The password needs to be roasted with the Roasting String if
coming over a FLAP connection, CP connections don't use
roasted passwords. The language specified will be used
when generating web pages, such as the get info pages.
Currently the only supported language is "english".
If the language sent isn't found, the default "english"
language will be used. The version string will be used
for the client identity, and must be less then 50
characters.
Passwords are roasted when sent to the host. This is done so they
aren't sent in "clear text" over the wire, although they are still
trivial to decode. Roasting is performed by first xoring each byte
in the password with the equivalent modulo byte in the roasting
string. The result is then converted to ascii hex, and prepended
with "0x". So for example the password "password" roasts to
"0x2408105c23001130"
toc_init_done
Tells TOC that we are ready to go online. TOC clients should first
send TOC the buddy list and any permit/deny lists. However toc_init_done
must be called within 30 seconds after toc_signon, or the connection
will be dropped. Remember, it can't be called until after the SIGN_ON
message is received. Calling this before or multiple times after a
SIGN_ON will cause the connection to be dropped.
toc_send_im <Destination User> <Message> [auto]
Send a message to a remote user. Remember to quote and encode the
message. If the optional string "auto" is the last argument, then the
auto response flag will be turned on for the im.
toc_add_buddy <Buddy User 1> [<Buddy User2> [<Buddy User 3> [...]]]
Add buddies to your buddy list. This does not change your
saved config.
toc_remove_buddy <Buddy User 1> [<Buddy User2> [<Buddy User 3> [...]]]
Remove buddies from your buddy list. This does not change your
saved config.
toc_set_config <Config Info>
Set the config information for this user. The config information
is line oriented with the first character being the item type,
followed by a space, with the rest of the line being the item
value. Only letters, numbers, and spaces should be used. Remember
you will have to enclose the entire config in quotes.
Item Types:
g - Buddy Group (All Buddies until the next g or the end of config
are in this group.)
b - A Buddy
p - Person on permit list
d - Person on deny list
m - Permit/Deny Mode. Possible values are
1 - Permit All
2 - Deny All
3 - Permit Some
4 - Deny Some
toc_evil <User> <norm|anon>
Evil/Warn someone else. The 2nd argument is either the string
"norm" for a normal warning, or "anon" for an anonymous
warning. You can only evil people who have recently sent you
ims. The higher someones evil level, the slower they can
send message.
toc_add_permit [ <User 1> [<User 2> [...]]]
ADD the following people to your permit mode. If
you are in deny mode it will switch you to permit
mode first. With no arguments and in deny mode
this will switch you to permit none. If already
in permit mode, no arguments does nothing
and your permit list remains the same.
toc_add_deny [ <User 1> [<User 2> [...]]]
ADD the following people to your deny mode. If
you are in permit mode it will switch you to
deny mode first. With no arguments and in permit
mode, this will switch you to deny none. If
already in deny mode, no arguments does nothing
and your deny list remains unchanged.
toc_chat_join <Exchange> <Chat Room Name>
Join a chat room in the given exchange. Exchange is
an integer that represents a group of chat rooms.
Different exchanges have different properties. For
example some exchanges might have room replication (ie
a room never fills up, there are just multiple
instances.) and some exchanges might have navigational
information, and some exchanges might have ... Currently
exchange should always be 4, however this may
change in the future. You will either
receive an ERROR if the room couldn't be joined
or a CHAT_JOIN message. The Chat Room Name
is case insensitive and consecutive spaces
are removed.
toc_chat_send <Chat Room ID> <Message>
Send a message in a chat room using the chat room
id from CHAT_JOIN. Since reflection is always on in
TOC, you do not need to add the message to your chat UI,
since you will get a CHAT_IN with the message.
Remember to quote and encode the message.
toc_chat_whisper <Chat Room ID> <dst_user> <Message>
Send a message in a chat room using the chat room
id from CHAT_JOIN. This message is directed at
only one person. (Currently you DO need to add this to
your UI.) Remember to quote and encode the message.
Chat whispering is different from IMs since it is linked
to a chat room, and should usually be displayed in the chat
room UI.
toc_chat_evil <Chat Room ID> <User> <norm|anon>
Evil/Warn someone else inside a chat room. The 3rd argument is either
the string "norm" for a normal warning, or "anon" for an anonymous
warning. Currently chat evil is not turned on in the chat complex.
toc_chat_invite <Chat Room ID> <Invite Msg> <buddy1> [<buddy2> [<buddy3> [...]]]
Once you are inside a chat room you can invite other people into
that room. Remember to quote and encode the invite message.
toc_chat_leave <Chat Room ID>
Leave the chat room.
toc_chat_accept <Chat Room ID>
Accept a CHAT_INVITE message from TOC. The server will send a
CHAT_JOIN in response.
toc_get_info <username>
Gets a user's info a GOTO_URL or ERROR message will be sent back to the
client.
toc_set_info <info information>
Set the LOCATE user information. This is basic HTML.
Remember to encode the info.
toc_set_away [<away message>]
if the away message is present, then the unavailable
status flag is set for the user. If the away message
is not present, then the unavailable status flag is
unset. The away message is basic HTML, remember to
encode the information.
toc_get_dir <username>
Gets a user's dir info a GOTO_URL or ERROR message will be sent back to the
client.
toc_set_dir <info information>
Set the DIR user information. This is a colon separated fields as in:
"first name":"middle name":"last name":"maiden name":"city":"state":"country":"email":"allow web searches"
Should return a DIR_STATUS msg. Having anything in the "allow web searches"
field allows people to use web-searches to find your directory info.
Otherwise, they'd have to use the client.
toc_dir_search <info information>
Perform a search of the Oscar Directory, using colon separated fields as in:
"first name":"middle name":"last name":"maiden name":"city":"state":"country":"email"
Returns either a GOTO_URL or ERROR msg.
toc_set_idle <idle secs>
Set idle information. If <idle secs> is 0 then the user isn't idle at all.
If <idle secs> is greater then 0 then the user has already been idle
for <idle secs> number of seconds. The server will automatically
keep incrementing this number, so do not repeatedly call with new
idle times.
toc_set_caps [ <Capability 1> [<Capability 2> [...]]]
Set my capabilities. All capabilities that we support need to
be sent at the same time. Capabilities are represented by
UUIDs.
toc_rvous_propose - Not Implemented Yet
toc_rvous_accept <nick> <cookie> <service> <tlvlist>
Accept a rendezvous proposal from the user <nick>.
<cookie> is the cookie from the RVOUS_PROPOSE
message. <service> is the UUID the proposal was
for. <tlvlist> contains a list of tlv tags followed by
base64 encoded values.
toc_rvous_cancel <nick> <cookie> <service> <tlvlist>
Cancel a rendezvous proposal from the user <nick>.
<cookie> is the cookie from the RVOUS_PROPOSE
message. <service> is the UUID the proposal was
for. <tlvlist> contains a list of tlv tags followed by
base64 encoded values.
toc_format_nickname <new_format>
Reformat a user's nickname. An ADMIN_NICK_STATUS or ERROR message will
be sent back to the client.
toc_change_passwd <existing_passwd new_passwd>
Change a user's password. An ADMIN_PASSWD_STATUS or ERROR message will
be sent back to the client.
TOC -> Client
==============
All user names from TOC to client are NOT normalized, and are
sent as they should be displayed. String are NOT encoded, instead
we use colons as separators. So that you can have colons inside
of messages, everything after the colon before :<Message> should
be considered part of the message (ie don't just "split" on colons,
instead split with a max number of results.)
SIGN_ON:<Client Version Supported>
This is sent after a successful toc_signon command is sent to TOC.
If the command was unsuccessful either the FLAP connection will
be dropped or you will receive a ERROR message.
CONFIG:<config>
A user's config. Config can be empty in which case the host was not able to
retrieve it, or a config didn't exist for the user. See toc_set_config
above for the format.
NICK:<Nickname>
Tells you your correct nickname (ie how it should be capitalized and
spacing)
IM_IN:<Source User>:<Auto Response T/F?>:<Message>
Receive an IM from some one. Everything after the third colon is
the incoming message, including other colons.
UPDATE_BUDDY:<Buddy User>:<Online? T/F>:<Evil Amount>:<Signon Time>:<IdleTime>:<UC>
This one command handles arrival/depart/updates. Evil Amount is
a percentage, Signon Time is UNIX epoc, idle time is in minutes, UC (User Class)
is a two/three character string.
uc[0]:
' ' - Ignore
'A' - On AOL
uc[1]
' ' - Ignore
'A' - Oscar Admin
'U' - Oscar Unconfirmed
'O' - Oscar Normal
uc[2]
'\0' - Ignore
' ' - Ignore
'U' - The user has set their unavailable flag.

If you continue to try, you will need to wait even longer.
989 - An unknown signon error has occurred $1
EVILED:<new evil>:<name of eviler, blank if anonymous>
The user was just eviled.
CHAT_JOIN:<Chat Room Id>:<Chat Room Name>
We were able to join this chat room. The Chat Room Id is
internal to TOC.
CHAT_IN:<Chat Room Id>:<Source User>:<Whisper? T/F>:<Message>
A chat message was sent in a chat room.
CHAT_UPDATE_BUDDY:<Chat Room Id>:<Inside? T/F>:<User 1>:<User 2>...
This one command handles arrival/departs from a chat room. The
very first message of this type for each chat room contains the
users already in the room.
CHAT_INVITE:<Chat Room Name>:<Chat Room Id>:<Invite Sender>:<Message>
We are being invited to a chat room.
CHAT_LEFT:<Chat Room Id>
Tells tic connection to chat room has been dropped
GOTO_URL:<Window Name>:<Url>

to use. (Java supports this.)
DIR_STATUS:<Return Code>:<Optional args>
<Return Code> is always 0 for success status.
ADMIN_NICK_STATUS:<Return Code>:<Optional args>
<Return Code> is always 0 for success status.
ADMIN_PASSWD_STATUS:<Return Code>:<Optional args>
<Return Code> is always 0 for success status.
PAUSE
Tells TIC to pause so we can do migration
RVOUS_PROPOSE:<user>:<uuid>:<cookie>:<seq>:<rip>:<pip>:<vip>:<port>
[:tlv tag1:tlv value1[:tlv tag2:tlv value2[:...]]]
Another user has proposed that we rendezvous with them to
perform the service specified by <uuid>. They want us
to connect to them, we have their rendezvous ip, their
proposer_ip, and their verified_ip. The tlv values are
base64 encoded.
Typical Signon Process
======================
Except for the section marked optional this is an sequential
process. Each line MUST occur before the following line.
* Client connects to TOC
* Client sends "FLAPON\r\n\r\n"
* TOC sends Client FLAP SIGNON
* Client sends TOC FLAP SIGNON
* Client sends TOC "toc_signon" message
* if login fails TOC drops client's connection
else TOC sends client SIGN_ON reply
* if Client doesn't support version it drops the connection
[BEGIN OPTIONAL]
* TOC sends Client CONFIG
* Client sends TOC permit/deny stuff
* Client sends TOC toc_add_buddy message
[END OPTIONAL]
* Client sends TOC toc_init_done message
SFLAP Documentation
===================
SFLAP is pretty much a FLAP connection except the DATA frame payload is a null
terminated string when traveling from client to host, it is NOT null
terminated when traveling from host to client. The FLAP Header is binary
data, and is in network byte order. The data portion is at offset 6, after the
header. The sequence number is sequential in each direction. So
packets from the server to client have one sequence number, while
the packets from the client to server have an independent
increasing number.
FLAP Header (6 bytes)
-----------
Offset Size Type
0 1 ASTERISK (literal ASCII '*')
1 1 Frame Type
2 2 Sequence Number
4 2 Data Length
Valid Frame Type Values
-----------------------
1 SIGNON
2 DATA
3 ERROR (Not used by TOC)
4 SIGNOFF (Not used by TOC)
5 KEEP_ALIVE
TOC SIGNON FRAME TYPE
---------------------
Sequence Number contains the initial sequence number used in each direction.
Data Length contains the payload length, with the payload described
below. The payload area is NOT null terminated.
Host To Client:
4 byte FLAP version (1)
Client To Host:
4 byte FLAP version (1)
2 byte TLV Tag (1)
2 byte Normalized User Name Length
N byte Normalized User Name (NOT null terminated)
TOC DATA FRAME TYPE
-------------------
Sequence Number contains the next sequence number.
Data Length is the length of the payload, including the null termination
from client to host.
