Chapter 7. The ThinLinc Client

7.1.4. The ThinLinc session life cycle

When the user has started a ThinLinc session the client login interface disappears from the desktop. The

client program continues to run in the background as long as the ThinLinc session is running. The client

enters a service mode where it handles services needed to fulﬁll the requested features. For example the

client handles the export of local printers, serial ports, and so on. When the ThinLinc session quits the

client service engine quits as well.

There are several ways a session can end. The most common one is that the user chooses to logout from

the session. That causes the session to ﬁnish on the server side. The ThinLinc server ﬁnds out that the

session has ﬁnished and disconnects the client. Another possibility is to intentionally disconnect the

client, without ﬁnishing the session on the server. This can be done by using the session menu. See

Section 7.1.5 below for information about how to do this. When the client disconnects before the session

running on the server is told to end, then the session will continue to run on the server. The next time the

user logs in the server will reconnect the user to the very same session. This way it’s possible to, for

example, disconnect a session at work, go home, reconnect to that session and continue to work.

If the user knows that there already is a session running on the server, but still wants to start a new fresh

session, then it’s possible to check the End existing session check box that exists in the client login

interface (advanced mode only). The client will then tell the server that it wants to end the existing

session (if it exists) and get a new one.

7.1.5. The session menu

When the ThinLinc session is authenticated and the ThinLinc session is running it’s possible to control

the session. For example it’s possible to change between full screen mode and window mode, and to

disconnect the ThinLinc client from the server.

To switch to windowed mode there is a session menu that pops up when the user press a predeﬁned key.

The default key for this is F8, but the key is conﬁgurable from the client options. See Section 7.4.1 for

more information about how to change this key. In the session menu you should select Full screen to

toggle full screen mode.

7.2. Running the ThinLinc client from the command line

To run the ThinLinc client from the command line you run the program tlclient, optionally followed by

options and a server name. The correct program syntax is as follows.

tlclient [options] [server][:port]

The optional server ﬁeld can be used to specify a ThinLinc server that should be predeﬁned in the server

ﬁeld when client is started. The optional port parameter causes the client to try to connect another

TCP/IP port number than the normal SSH port when establishing it’s secure connection to the ThinLinc

server. More information about custom SSH settings is available at Section 7.4.5.

The ThinLinc client is highly controllable from the command line by the use of command line

arguments. Many parts of the client can be controlled this way. The more simple things to control is the

server or user name. It is possible to force settings and lock tabs and ﬁelds in the conﬁg interface to

prevent them from being changed.
