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. 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.

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. 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.

ERROR:<Error Code>:Var args

Wait 10 minutes and try again. 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>
Goto a URL. Window Name is the suggested internal name of the window to use. (Java supports this.)

DIR_STATUS:<Return Code>

PAUSE
Tells TIC to pause so we can do migration Except for the section marked optional this is an sequential process. Each line MUST occur before the following line. 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. Offset Size Type 0 1 ASTERISK (literal ASCII '*') 1 1 Frame Type 2 2 Sequence Number 4 2 Data Length 1 SIGNON 2 DATA 3 ERROR (Not used by TOC) 4 SIGNOFF (Not used by TOC) 5 KEEP_ALIVE 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. 4 byte FLAP version (1) 4 byte FLAP version (1) 2 byte TLV Tag (1) 2 byte Normalized User Name Length N byte Normalized User Name (NOT null terminated) Sequence Number contains the next sequence number. Data Length is the length of the payload, including the null termination from client to host. This protocol description may not be complete.
