Logfile placement

The ThinLinc client logs its activities in human readable log files. For the common use case of running one client at a time, the log file is always called tlclient.log. Once the first client has been closed and a second client is started, the log file of the first client is renamed tlclient.old.log and the second client creates its log file, again called tlclient.log. At most two log files are kept at a time for this use case - one for the current client and one for the most recently closed client. If the file tlclient.old.log exists before starting a client, that file will be permanently deleted once the client is started.

Another, more rare use case is running two or more clients simultaneously. The first log file is again called tlclient.log and the log files of any additional clients are called tlclient2.log, tlclient3.log, and so on, up to a maximum of nine active log files. Once the maximum number of active log files is reached, any additional clients started will not have any log files associated with them.

If a client with an associated log file is closed, that log file is considered inactive. If a new client is started when less than nine log files are active, the client will once again have a log file associated with it. Note, however, that a client can reuse an inactive log name. In this context, reuse means that if e.g. the client associated with log file tlclient3.log is closed and a new client is opened, it is possible for the log file of the new client to again be named tlclient3.log.

Every time a new client is opened, all .old.log files will be permanently deleted and all inactive log files will be renamed from .log to .old.log. That means that when running multiple clients simultaneously, there can be several .log files as well as several .old.log files.

The locations of the log files differ between Linux and Windows systems and are explained below.

Linux log file

On Linux systems the logfile is located in the home directory for the user that runs the ThinLinc client. The path is ~/.thinlinc/tlclient.log.

Windows log file

On Windows systems the logfile is located in the directory referenced from the %TMP% variable. The value of this variable can be achieved by running any of the following commands in a Windows command window.

C:\> echo %TMP%


C:\> set

Observe that some directories in the Windows %TMP% path may be flagged as hidden by the Windows system. This means that you need to change directory options to display hidden files and directories to navigate to the log file.

macOS log file

On macOS systems the logfile is located in the home directory for the user that runs the ThinLinc client. The path is ~/.thinlinc/tlclient.log.
