Changing the Default Network Configuration

The PCoIP Management Console virtual machine includes a network configuration tool called NetworkManager TUI (textual user interface) that lets you change the PCoIP Management Console’s default network configuration. You can use this tool to assign a static IP address to the PCoIP Management Console. Do NOT modify the DNS configuration with this tool.

Tip: Ensure you have correct DNS A and DNS PTR records set

Before you run the Network Configuration Tool, be sure to set the correct DNS A record and DNS PTR record in your DNS server for the PCoIP Management Console. If the records are already set, ensure you use the same IP address associated with the DNS records.

Note: Give PCoIP Management Console a fixed IP address

Teradici recommends that you give the PCoIP Management Console a fixed “static” IP address, either through a DHCP reservation or by Assigning a Static IP Address using the PCoIP Management Console’s network configuration tool. If a PCoIP Management Console is configured using DHCP and the IP address of the PCoIP Management Console changes, the endpoints it manages will be unable to connect to it.

Launching the PCoIP Management Console Network Configuration Tool

To launch the network configuration tool:

  1. Log in to the PCoIP Management Console virtual machine console. For instructions, see Accessing the PCoIP Management Console Virtual Machine Console.

  2. Type the following command at the command line to launch the network configuration tool:
    sudo nmtui
    Network Manager Tool
    Network Manager Configuration Tool

    Info: Default configuration

  1. Launch the PCoIP Management Console’s network configuration tool.

  2. Select Edit a connection.

  3. Select eth0 then tab and select < Edit... >.

  4. Tab to < Show > to access and configure your IPv4 parameters:

    • IPv4 CONFIGURATION: Set to Manual for a static IP configuration. Be sure to enter your network, see screen shot below.

    • Addresses: Enter the IP address you selected for your Management Console, ensuring you use the appropriate slash notation to define your subnet mask.

    • Gateway: Enter your default gateway IP address for the Management Console's network.

    • DNS servers: Enter the IP address of your DNS servers.

    • Search domains: Enter the domains used in your deployment in the format of mydomain.local.

    sudo systemctl restart network

Note: Shown next are example IP addresses

The IP addresses shown next are for example purposes only. Enter your own information.

Important: Correctly identifying subnets

Addresses and subnets must be correctly defined otherwise the PCoIP Management Console will not operate. Subnets are defined through the slash notation used in the Addresses field. The example of /24 represents Your network may use different subnet sizes.
