Chapter 16. Administration of ThinLinc using the Web Administration Interface
• Load allows you to check the current server load on both ThinLinc and application servers.
• Sessions allows you to terminate, shadow or view details of sessions. This feature is described in more
detail in the next section, Section 16.3.2.1
16.3.2.1. The Sessions Menu
When you select the sessions menu, a table with all currently active users is displayed. To perform
additional tasks, click on the corresponding user name. This will bring up the session details page, which
displays all the session parameters for each session the user has running. The information table is
described below.
• Terminal Server : The DNS host name of the server that is hosting this session. If you only have one
ThinLinc server, this server will host all sessions. If you have several ThinLinc servers in a cluster,
new sessions will be created on the server with the lightest load.
• Display Number : Each session on a certain server has a unique number, the X Window System
display number. Display zero is reserved, and never used for ThinLinc sessions.
• Terminal ID : An identification of the thin terminal. This is the terminal’s ethernet hardware address
(MAC address).
• Framebuffer Size : The size (resolution) of the active session.
• Local Screen Size : The size (resolution) of the terminal’s screen.
• Session process ID : The PID (process identification number) of the tl-session process, which is the
parent for all processes belonging to a certain session.
• Command : The command line that was specified when starting this session. This is usually empty
for full desktop sessions.
Below each table, there are two buttons:
• Terminate Session : By clicking this button, you can terminate a session immediately. Caution: This
can lead to data loss, since applications running on the ThinLinc servers may not hold unsaved data.
• Shadow Session : This button will generate a ThinLinc "launch file" (see Section 8.7.1) that starts
the native ThinLinc client, preconfigured to shadow the current user.
Note: The user will not be informed that shadowing is in progress, unless tl-shadow-notify is
enabled.
16.3.3. The VSM Module
VSM contains information about VSM Master and Agent services. This module allows you to start or
stop the services, and modify a subset of the configuration options.
