-====== Synchronet Inter-BBS Instant Message Module ====== +====== Instant Message ====== 
-FIXME+ 
 +The Synchronet Instant Message module is used to provide a real-time inter-BBS instant message feature for participating systems. 
 + 
 +This module is normally invoked from the [[chat_sec|"Chat" menu]] or from the [[:module:PrivateMsg]] module with the 'I' key. 
 + 
 +===== Install ===== 
 +==== Chat Menu ==== 
 +If you're using the default ''[[chat_sec]]'' menu module, you should already have it installed on that menu (the ''I'' command key). 
 + 
 +==== Global Hotkey ==== 
 +To get access to instant-message module from virtually //anywhere// within the BBS (e.g. using Ctrl-P), install the (new) [[:module:PrivateMsg]] module in SCFG->System->Loadable Modules->Private Msg (the default, ''privatemsg'', should be all you need): 
 +  Private: (T)elegram, (M)essage, (C)hat, (I)nterBBS, or (Q)uit: 
 + 
 +==== Logon Event ==== 
 +To display a list of currently active users (on other inter-BBS instant message capable systems) during user-logon, add an external program to [[util:SCFG]]->External Programs->Online Programs->Main (or your section of choice)->Available Online Programs... and configure as follows: 
 + 
 +<file> 
 +Name                       Synchronet IMSG List 
 +Internal Code              SBBSIMSG 
 +Command Line               ?sbbsimsg -l 
 +Multiple Concurrent Users  Yes 
 +Execute on Event           Logon, Only 
 +Pause After Execution      Yes 
 +BBS Drop File Type         None 
 +</file> 
 + 
 +All other settings can be left with their default values (No/None/blank). 
 + 
 +  
 +===== History ===== 
 + 
 +History of this module/feature: 
 + 
 +==== Original (2001) ==== 
 +  * Queried systems using Finger (TCP port 79) 
 +  * Sent message using SMTP-SOML (TCP port 25) 
 + 
 +==== Rev 1.11 (2002) ==== 
 +  * Queried system using both TCP and UDP-Finger (port 79) 
 +  * Still sent messages using SMTP-SOML 
 + 
 +==== Rev 1.22 (2007) ==== 
 +  * Queried using SYSTAT/ActiveUser protocol (TCP & UDP port 11) in addition to Finger (TCP and UDP port 79) 
 +  * If send via SMTP failed, used MSP protocol (TCP port 18) 
 + 
 +==== Rev 1.25 (2009) ==== 
 +Removed Finger (both TCP and UDP support), SYSTAT-TCP and SMTP support, so it now *only*: 
 +  * Queries using SYSTAT/ActiveUser protocol over UDP port 11 
 +  * Sends messages using MSP (TCP port 18) 
 + 
 +So, while **originally** the requirements for systems to participate in the instant-message network were: 
 +  * Synchronet SMTP Server listening on TCP port 25 
 +  * fingerservice.js listing on TCP port 79 
 + 
 +**Now**, the requirements are: 
 +  * activeuserservice.js (or fingerservice.js) listening on UDP port 11 
 +  * mspservice.js listening on TCP port 18 
 + 
 +===== List File ===== 
 + 
 +The heart of the instant message module is the ''[[dir:ctrl]]/sbbsimsg.lst'' file. 
 + 
 +This file is generated daily on [[bbs:Vertrauen]] and distributed via FTP as [[ftp://vert.synchro.net/sbbsimsg.lst]]. 
 + 
 +The event module ''[[dir:exec]]/getimsglst'' is normally run as a timed event (configured in [[util:SCFG]]->External Programs->Timed Events) and used to pull the list file from Vertrauen via FTP, usually daily. 
 + 
 +The List File is generated daily on Vertrauen through the use of the ''[[module:sbbslist]].js'' module's ''imsglist'' command-line option. This sbbslist option parses the Synchronet BBS List and finds listed-systems that meet the minimum requirements to be included in the instant-message list and re-generates the ''sbbsimsg.lst'' file. 
 + 
 +==== Requirements ==== 
 +Since Vertrauen uses its [[http://synchro.net/sbbslist.html|Synchronet BBS List]] as the source of BBSes which may be instant-message capable, the first requirement is that a system is listed in this database. 
 + 
 +To have your system listed, either: 
 +  - login to Vertrauen and create your BBS entry or,  
 +  - preferably, run the [[sbbslist]] module on your own BBS and have it synchronized with Vertrauen and the rest of DOVE-Net or FidoNet via the ''SYNCDATA'' networked message area 
 + 
 +The following services **must** also be reachable via the public-Internet for a system to be listed in the Instant Message module List File (''sbbsimsg.lst''): 
 +  - SYSTAT/ActiveUser service (using the [[service:Finger]] service) on UDP port 11 
 +  - MSP service (using the [[service:MSP]] service) on TCP port 18 
 + 
 +This is normally accomplished by adding the following services to a BBS's ''[[dir:ctrl]]/[[config:services.ini]]'' file: 
 + 
 +<file ini> 
 +[ActiveUser-UDP] 
 +Port=11 
 +MaxClients=10 
 +Options=UDP | NO_HOST_LOOKUP 
 +Command=fingerservice.js -u 
 +</file> 
 + 
 +<file ini> 
 +[MSP] 
 +Port=18 
 +MaxClients=10 
 +Command=mspservice.js 
 +</file> 
 + 
 +You can use [[http://cvs.synchro.net/scanmyports.ssjs|this page]] to help determine if the required services are publicly-reachable on your system. 
 + 
 +Once a system is listed in the Synchronet BBS List on Vertrauen and the required services are confirmed publicly-reachable on the Internet, that system should appear in the shared ''sbbsimsg.lst'' file within 24 hours.
