Administering the PCoIP Connection Manager and PCoIP Security Gateway¶

Starting or Stopping the PCoIP Connection Manager¶

To start, stop, or restart the PCoIP Connection Manager:

sudo service connection_manager start|stop|restart

Restarting the PCoIP Connection Manager may take up to a minute to complete. Clients cannot establish PCoIP sessions through it until restart is complete.

Starting or Stopping the PCoIP Security Gateway¶

To start, stop, or restart the PCoIP Security Gateway:

sudo service security_gateway start|stop|restart

Enable the PCoIP Security Gateway¶

If you deploy Teradici Platform over a WAN, using a PCoIP Security Gateway is highly recommended.

To enable the PCoIP Security Gateway:

Open /etc/ConnectionManager.conf in a text editor and ensure the following line is present:
```
SecurityGatewayEnabled = true
```
Save the file and exit the editor.
Open /etc/SecurityGateway.conf in a text editor and set the following field:
```
ExternalRoutableIP = <ip address reachable by clients>
```
Save the file and exit the editor.
Open /etc/security/limits.conf in a text editor and ensure that the PCoIP Security Gateway's file descriptor limits are set to 11000 or higher.

The file descriptor limits look like this:
```
security_gateway soft nofile 11000

security_gateway hard nofile 11000
```
Restart the PCoIP Connection Manager:
```
service connection_manager restart
```
Restart the PCoIP Security Gateway:
```
service security_gateway restart
```

Disable the PCoIP Security Gateway¶

If your users are behind your firewall and will not access their desktops from the WAN, you do not need to use the PCoIP Security Gateway. You can optionally disable it using this procedure.

To disable the PCoIP Security Gateway:

Open /etc/ConnectionManager.conf in a text editor and set SecurityGatewayEnabled to false:
```
SecurityGatewayEnabled = false
```
Save the file and exit the editor.
Restart the PCoIP Connection Manager:
```
service connection_manager restart
```
