Parameters in /vsm/

Parameters in the /vsm folder are used by both the VSM agent and the VSM server. Neither of them need to be changed on a normal ThinLinc installation. These configuration parameters reside in /opt/thinlinc/etc/conf.d/vsm.hconf.

/vsm/tunnel_bind_base

The tunnels set up by the client to access various resources (audio, serial port, network resources, local printer) need one port number each on the server running the VSM agent the client is connected to. This parameter decides the lowest such port that is allocated by the VSM agent. Each user has a port range defined by the formula:

/vsm/tunnel_bind_base + display × 10 + service_slot

where the service_slot depends on which service will use the tunnel. This port range is however used only for sessions with display numbers less than 100. See TCP ports used by ThinLinc for an in-depth explanation of port allocation.

Note

This parameter should normally not be changed.

/vsm/tunnelservices

There are several parameters under the /vsm/tunnelservices folder. Each one decides which ports are used as server-side termination points for the tunnels used to access client resources. See TCP ports used by ThinLinc for an in-depth explanation of port allocation.

Note

None of these parameters should normally be changed.

/vsm/tunnelslots_per_session

The number of ports to reserve for tunnel port endpoints on the server. The number of ports actually used depends on the number of services defined under /vsm/tunnelservices . We recommend letting this parameter have its default value (10), since that provides a margin for future services. See TCP ports used by ThinLinc for an in-depth explanation of port allocation.

Note

This parameter should normally not be changed and must not be changed whilst there are any running sessions.

/vsm/vnc_port_base

The port base for VNC communication. The VNC protocol runs on one port per active user on the VSM agent host, and this is the base of the numbers used. That is, for the first user, the port will be /vsm/vnc_port_base + 1, for the second user /vsm/vnc_port_base + 2 and so on. This algorithm is used only for display numbers below 100. See TCP ports used by ThinLinc for an in-depth explanation of port allocation.

Note

This parameter should normally not be changed.

/vsm/vsm_agent_port

VSM agent communication. This is the port that the VSM server connects to on VSM Agents. This traffic is not encrypted.

Note

This parameter should normally not be changed

/vsm/vsm_server_port

The port that the VSM server listens to.

Note

This parameter should normally not be changed
