Beta Software

Users who wish to test pre-release versions of software can do so by selecting the beta distribution channel before installing. Select the beta channel, by editing editing the /etc/apt/sources.list.d/pcoip.list file and commenting the appropriate lines:
```
sudo vi /etc/apt/sources.list.d/pcoip.list
```
Teradici does not recommend installing beta software in production systems.

Kernel Network Configuration¶

The pcoip-configure-kernel-networking.sh script is installed with the Software Client for Linux. This script tunes the kernel networking configuration to facilitate the network performance required by the Client. You need to run this script after installing the PCoIP Software Client for Linux.

Run the following command:

$ sudo pcoip-configure-kernel-networking --persistent

The script contains the following parameters:

rmem_default: A kernel parameter that controls the default size of receive buffers used by sockets.
rmem_max: A kernel parameter that controls the maximum size of receive buffers used by sockets.

rmem_max size

This parameter must be at least as large as rmem_default/

ipv4.udp_mem: A kernel parameter that controls the maximum total buffer-space to allocate.
netdev_max_backlog: A kernel parameter that controls the maximum size of the receive queue.
