  Hi Teamviewer.

  I'm doing some programming where I'm sending this file line by line to a linux rsyslog server,
  for a centralized logging on all the connection for the different PC's running TeamViewer.

  999999999       FSMi       12-06-2013 08:03:28     12-06-2013 08:04:08     User  RemoteControl   {15DB9578-DD81-46DF-B120-CEB61E59861B}

  What is {15DB9578-DD81-46DF-B120-CEB61E59861B} ??

  I have seen that 999999999 , just a fake one , was only 8 digits in some older logs ,
  Shouldn't it always be 9 digits ??

  Thanks Michael.
