Virtual Environment @ UPV

OpenVPN Client configuration

On the routertestar.dsic.upv.es and routertestaq.dsic.upv.es an OpenVPN server is installed. Users can connect to one of the routers via OpenVPN. A user certificate needs to be created and added to an OpenVPN client configuration. To create a OpenVPN client configuration please follow the following steps:

  1. Log into routertestar.dsic.upv.es
  2. Become root user
  3. Read the OpenVPN CA password in /root/testar-ca-key-password.txt
  4. Run the following command: openvpn-users.sh
  5. Follow the instructions of the script and give the CA password when asked. 2 OpenVPN configuration files will be created and the certificates will be distibuted to the 2 testar routers
  6. Copy the generated OpenVPN configurations files from the /root/ directory to your own computer with scp/winscp
  7. Distribute the OpenVPN configuration files to the end user, so they can import this in their OpenVPN client.

DHCP address space

Both the routertestaq and routertestar have a DHCP server (DNSMASQ) running that will give a IP to a virtual machine according to the mac address of the virtual machine.

The mac address needs to be set to manual in the network interface settings of the virtual machine and the mac address needs to start with: 00:50:56:UV:WX:YZ where UV::WX:XY has to be set according to the mapping below. The MAC address can only be changed when the virtual machine is switched off.

In the DHCP server the mac addresses are reserved for the ranges from 10.101.0.2 until 10.101.0.200 on the routertestaq server and from 10.102.0.2 until10.102.0.200 for the routertestar server.

MAC address mapping:

00:50:56:01:0X:YZ maps to 10.101.0.XYZ on the routertestaq

00:50:56:02:0X:YZ maps to 10.102.0.XYZ on the routertestar

When the last octet is below 10 the X and Y will be set to 0. When the last octect is below 100 only the X will be set to 0.

Example:

Below you can find how the manual MAC address (00:50:56:01:00:06) is set for a virtual machine that will get the 10.101.0.6 as IP address from the DHCP. The the octet is 6 so the X=0, Y=0 and Z=6.
