===== SYSOP introduction =====
Several tables are available for controlling the YCS server. The tables are located in the //**/opt/YCS**// directory.\\
\\
The tables can be edited with an editor. The YCSServer checks every 30 seconds whether a table has been changed and reads it in automatically if a change has taken place and include the new info to the running system.

  * [[ycsserver:sysop:server:dgidlist | DG-ID List]]
  * [[ycsserver:sysop:server:dr2xlist | DR-2X List (new info to DG-ID ondemand)]]
  * [[ycsserver:sysop:server:control | CONTROL]]
  * [[ycsserver:sysop:server:keytable | KEY-Table]]
  * [[ycsserver:sysop:server:ysflink | YSFLink]]
  * [[ycsserver:sysop:server:fcslink | FCSLink]]

So that the YCS server can be reached from a HOTSPOT (MMDVM, PiStar, OpenSpot), the YCS server must be registered in the YSFRegister system. This can be done via the page https://register.ysfreflector.de/. Please follow the scheme when registering so that the YCS can be found together with Serach "(YCS").\\

For new features like YSFLink and FCSLink you need to download the //**YSFHosts.txt**// file.\\
\\
An example would be following line in root's crontab, that fetches the reflector-list each 30 minutes:\\
\\
//**sudo crontab -e**//\\
\\
add following line:\\
\\
//***/30 * * * * wget -O /opt/YCS/YSFHosts.txt http://register.ysfreflector.de/export_csv.php**//\\
