This is no longer a valid tutorial after the restructuring after the cyber attack, and openconnect should not longer be recommended to anyone. The VPN software is available behind the access controlled site Portal.ru.is
These instructions guide you through the process of downloading and installing Open Connect which is an open source VPN client.
Note: the application you installed may look differently than the one shown in this guide.
Open the OpenConnect VPN client by clicking on the icon.
Figure 5 shows the window when the OpenConnect VPN client is opened and it allows you to select a server. The first time you open the GUI you will have no configured servers. To configure a server, you need to click the small cogwheel button on the right side of the sever dropdown list (red). In the drop down list you select New Profile.
Figure 6 shows the window that pops up after selecting New Profile.
You need to check in Customize and type SR VPN in the Name window and vpn.ru.is in the Gateway window and then select Save. Figure 7 shows the correct configuration.
After saving the profile, everytime you open the OpenConnect VPN client you will see the window shown in Figure 8.
when you select Connect you will get the window seen in Figure 9 and as you can see in GROUP it should say RU. If not select it from the drop down list.
After clicking on OK you will be asked for username and password (provided by Sleep Revolution team). The username should be your_username@sleep.ru.is where your_username is specific to you.
After login the VPN is connected and you are now able to connect to a virtual machine to access data.
