-==== Event Semfiles ====+==== Sysop Available for Chat ==== 
 +If the file ''[[dir:ctrl]]/sysavail.chat'' exists, then the sysop availability for chat with users can be indicated and users will be allowed to page the local sysop to chat. 
 +==== Event Semaphore Files ====
  
-Events that have been configured in [[util:SCFG]]->External Programs->Timed Events can be externally triggered by creating the file ''[[dir:data]]///<event>//.now'', where ''//<event>//'' is the "Internal Code" if the timed event. Events are executed (serially) by the [[server:terminal|Terminal Server]] Event Thread.+Events that have been configured in [[util:SCFG]]->External Programs->Timed Events can be externally triggered by creating the file ''[[dir:data]]///<event>//.now'', where ''//<event>//'' is the "Internal Code" of the corresponding timed event. Events are executed (serially, by default) by the [[server:terminal|Terminal Server]] //Event Thread//.
  
 Example (forcing execution of the FidoNet import event): Example (forcing execution of the FidoNet import event):
  
-  touch /sbbs/data/fidoin.now+  touch /sbbs/data/fidoin.now
      
-==== QWK Pack Semfiles ====+==== QWK Pack Semaphore Files ====

-  touch /sbbs/data/pack0001.now+  touch /sbbs/data/pack0001.now
      
 QWK packets are created in the ''[[dir:data]]/file'' directory with a filename of ''//<user>//.qwk''. If a QWK packet already exists for the user, it will be opened and appended with any new messages. QWK packets are created in the ''[[dir:data]]/file'' directory with a filename of ''//<user>//.qwk''.

-==== QWK Pre-pack Semfile ====+==== QWK Pre-pack Semaphore File ====
  
 The QWK pre-pack event (which runs automatically once a day) can be forced by creating the file ''[[dir:data]]/prepack.now''. The QWK pre-pack event (which runs automatically once a day) can be forced by creating the file ''[[dir:data]]/prepack.now''.
  
-==== QWKnet Call-out Semfile ====+==== QWKnet Call-out Semaphore File ====
  
 QWK Network hub call-out events can be forced to execute by creating the file ''[[dir:data]]/qnet///<hub-id>//.qwk'', where ''//<hub-id//'' is the QWK-ID of the QWKnet Hub configured in [[util:SCFG]]->Networks->QWK. QWK Network hub call-out events can be forced to execute by creating the file ''[[dir:data]]/qnet///<hub-id>//.qwk'', where ''//<hub-id//'' is the QWK-ID of the QWKnet Hub configured in [[util:SCFG]]->Networks->QWK.

-  touch /sbbs/data/qnet/vert.now+  touch /sbbs/data/qnet/vert.now 
 +   
 +==== QWKnet Timed-event Semaphore Files ==== 
 +After receiving and processing a QWKnet ''.QWK'' or ''.REP'' file, Synchronet will //touch// the ''[[dir:data]]/**qnet-qwk**.now'' or ''[[dir:data]]/**qnet-rep**.now'' files to trigger timed events of those names, if they exist, to execute.
  
-===== Timestamp Semfiles =====+==== Pause Server Semaphore File ==== 
 +The existence of the file ''[[dir:ctrl]]/pause'' (or a supported service/host variant) will cause that server to stop accepting incoming client connections. Any existing clients/connections will continued to be service while the server is paused. Removing the file will "resume" the server. 
 +===== Timestamp Semaphore Files =====
  
-These semaphore files are not deleted when the operation is triggered, so the date/time stamp of the file must be updated (i.e. the file must be "touched") to trigger the operation again:+Timestamp semaphore files are not deleted when the operation is triggered, so the date/time stamp of the file must be updated (i.e. the file must be "touched") to trigger the operation again:
  
-==== Recycle Semfiles ====+On a multi-host BBS, the servers and services on a specific host can be signaled by "touching" the file ''[[dir:ctrl]]/<semfile>.//<hostname>//'' or ''[[dir:ctrl]]/<semfile>.//<host.domainname>//'' instead.
  
-Synchronet servers and services can be forced to terminate all threads, close sockets, and reload their configuration files by "touching" the file ''[[dir:ctrl]]/recycle''.+A specific server or service may be signaled by "touching" the file ''[[dir:ctrl]]/<semfile>.//<service>//'' instead, where ''//<service>//'' is one of: ''term, ftp, mail, web, or services''.
  
-On a multi-host BBS, the servers and services on a specific host can be recycled by "touching" the file ''[[dir:ctrl]]/recycle.//<hostname>//'' or ''[[dir:ctrl]]/recycle.//<host.domainname>//'' instead.+==== Recycle Semaphore Files ====
  
-A specific server or service may be recycled by "touching" the file ''[[dir:ctrl]]/recycle.//<service>//'' instead, where ''//<service>//'' is one of: ''telnet, ftp, mail, web, or services''.+Synchronet servers and services can be forced to terminate all threads, close sockets, and reload their configuration files by "touching" the file ''[[dir:ctrl]]/recycle''.
  
 Servers or services that have the ''NO_RECYCLE'' option flag set (in the ''[[sbbs.ini]]'' file) will **not** be recycled by external touching of the //recycle// semaphore file. Servers or services that have the ''NO_RECYCLE'' option flag set (in the ''[[sbbs.ini]]'' file) will **not** be recycled by external touching of the //recycle// semaphore file.
  
-==== Shutdown Semfiles ====+:!:\\ 
 +If touching the ''recycle'' semaphore file does not trigger an ''sbbs'' server/services recycle (e.g. on Linux), see [[faq:nix#recycle]] for details on why that may be. 
 + 
 +==== Shutdown Semaphore Files ====
  
 Synchronet servers and services can be forced to terminate (shutdown) by "touching" the file ''[[dir:ctrl]]/shutdown''. Synchronet servers and services can be forced to terminate (shutdown) by "touching" the file ''[[dir:ctrl]]/shutdown''.
  
-On a multi-host BBS, the servers and services on a specific host can be recycled by "touching" the file ''[[dir:ctrl]]/shutdown.//<hostname>//'' or ''[[dir:ctrl]]/shutdown.//<host.domainname>//'' instead. +==== Clear Failed Login List Semaphore Files ====
- +
-A specific server or service may be shutdown by "touching" the file ''[[dir:ctrl]]/shutdown.//<service>//'' instead, where ''//<service>//'' is one of: ''telnet, ftp, mail, web, or services''.+
  
 +A sysop can clear the in-memory //Failed Login List// (temporary IP address ban list) by "touching" the file ''[[dir:ctrl]]/clear''.
