When importing the supplied files and creating a VM, the information such as IP addresses and subnet masks are generic addresses and need to be changed to accommodate the network that the VM will be operating in. The procedure below describes how to configure the IP addresses etc to be able to communicate with the VM just created.

  • Startup GCEMS VM and Log in. Default username/password = excelsw/excelsw

The first Boot process may take longer than normal due to MAC changing on NIC card and DHCP requests.

  • Open a terminal by right clicking on the desktop and selecting ‘open terminal’. See below.

    • In terminal, switch to root user and start network configuration tool by entering the commands below. (root password = excel2)

[excelsw@localhost ~]$ su Password: [root@localhost excelsw]# system-config-network &

  • Select device eth0 and press ‘Edit’ button.

  • Edit the properties as necessary to connect to the same subnet as IMG CTRL 0 Port. Screen capture below is used as a reference.

 

Ethernet port eth0 needs to be secure. Therefore, eth0 should be configured on a restricted/private network. Eth0 will connect to the Ctrl0 port which is used for operations, administration, maintenance & provisioning. (OAMP)

  • Select the ‘DNS’ tab from the Network Configuration box and configure the hostname, DNS, and Domain as necessary. Save all changes through the file menu. File > Save. Screen capture below is used as a reference.

  • Delete any instances with nickname of eth.bak. These instances are no longer necessary. See screen capture below

  • Activate eth0 by pressing Activate  

    in the tool bar.

  • Repeat steps above if a second Ethernet interface is required.

  • Close the ‘Network Configuration’ tool.

    • Go to /home/excelsw and run the xlsshkeygen tool. Running this tool will create a new set of SSH keys for this VM. For security purposes, it is recommended that this tool be run once on each instance of GCEMS VM.

# ./xlsshkeygen

  • Restart the network.

# service network restart

  • Use ping command to verify network connectivity to and from other devices in the network.

  • At this point, the configuration will function as if it were GCEMS server hardware. VM is configured for single server installation by default. To run a redundant GCEMS Configuration, re-run the GCEMS installation and select the appropriate options. See IMG 1010 - Software Installation and Setup on how to install and setup the GCEMS and IMG into a network. If VNC is needed then see IMG 1010 - Configuring Remote Desktop.
