+Other logging locations apart from the system's log are:
+  * X2Go Server: ''/var/log/syslog''
+  * X2Go Client: stderr (use ''%%--debug%%'')
+  * PyHoca-GUI: stderr (use ''%%--libdebug --debug%%'')
+  * Xsession itself: ''$HOME/.xsession-x2go-errors''

 The log files normally get written to ''/var/log/x2gobroker/*.log''
+You can also run
+<file>
+root@broker:~$ x2gobroker-daemon-debug
+</file>
+as user ''root''. This is equivalent to running the broker daemon provided by the package ''x2gobroker-daemon'', but you will see all output piped to stderr while the X2Go Session Broker daemon runs in foreground mode.
 ==== Python X2Go / PyHoca Debugging ====
-The PyHoca clients both have a ''--libdebug'' option. Run ''pyhoca-gui'' or ''pyhoca-cli'' from the command line with that option enabled and you get blasted with debug output.

+==== Debugging x2goclient on Windows ====
+This is a bit tricky. You need to run the debug version of x2goclient in a cmd window. The debug version is part of the xgoclient installation package for Windows and is called ''x2goclient.debug.exe''. If it is not available on you machine re-run the installer.
+Run ''<path_to_your_installation>\x2goclient --debug --libssh-debug --libssh-packetlog 2>logfile.txt'' (+ further options you might require) and run your session as usual. The session log file ''logfile.txt'' will be created in the current directory and can be opened e.g. with notepad.
+Run ''x2goclient --help'' for available options.
+<note important>important The options are always prefixed by two ''-'', your browser might display them as one!</note>
