FastX log files

System Logs

  • /var/log/fastx  — stdout and stderr of the FastX Web service
  • If FastX is version 2.3 or later, and the Linux system uses systemd init system (default on RedHat/Centos 7.14, Debian 8, Ubuntu 15, or SUSE 12 or later), then FastX will not log in /var/log/fastx, but the log can be viewed with the command journalctl –unit=fastx.service.

Session Logs

FastX stores all logs related to sessions in the user’s $HOME/.fastx_server/hostname.example.com/FX-sessionId/ directory
The files include:

  • app_error — stderr output of the command when the session was started
  • app_output — stdout output of the command when the session was started
  • server_log — output of the Xorg server
  • xorg.log  — detailed output of Xorg
  • monitor_output — logs of communication with the FastX web server
