Host-Only Networking in VirtualBox

This guide is to teach a user how to enable host-only networking on virtual box.

1. Open your virtual box preferences.


2.  Select the “Network” tab once you are in the preferences menu. Once you have done this Select “Host-only Networks”. The white box will be empty. To fill it as seen below all you have to do is click the green plus sign on the right side of the menu. If done correctly it should look exactly as below. Click ok to continue.


3.  Select your virtual machine (In my case this was an Ubuntu VM, this does not matter and will work on any virtual machine). Once it is highlighted click “Settings” and tab over to the “Network” menu.  All that is left is to select “Host-only Adapter” next to “Attached to:” in this menu. Once that is complete it should automatically select the host-only adapter we just created. If done correctly it should look exactly like below. Click ok to continue.


Congratulations! You just created a host-only network for your virtual machine.  If done correctly it should be unable to access the internet at this time.

Connecting to the WMU CS Login Servers Using PuTTY

EDIT: For CS3500 Students run :

wget cs.wmich.edu/~s4demore/Shell_Exercises.tar.gz

and extract them into your current directory with:

tar xvzf Shell_Exercises.tar.gz

While Windows does not have built in SSH functionality, there is a piece of software we recommend that brings SSH to Windows. PuTTY (available at http://www.chiark.greenend.org.uk/~sgtatham/putty/) is simple to use, and allows you to use your computer science account from your Windows computer when on a campus network or connected to the VPN.

When you start it, PuTTY will look like the following image.

To connect to the login servers, fill out the “Host Name” box with “username@login.cs.wmich.edu” where “username” is replaced with your BroncoNet ID. Ensure that the port is set to 22, and that the connection type is set to “SSH.” Once all this information is entered, click on “Open” to start a session. You will be prompted for your password, and when you type it, nothing will appear on the screen . Once you have finished typing your password, hit the Return key, and if everything went well, you will be logged into a shell as your user.

Downloading and Using the WMU VPN

For accessing WMU services from outside of the campus networks, a Virtual Private Network (VPN) is a necessity. The VPN client provided by the university must be used for this purpose. This post will show how to download and run the VPN software.

The client is available for download on the GoWMU homepage, under the “Software Downloads” panel. The image below shows what that panel will likely look like.

When you click the link for the VPN downloads, the page will reload, and you will have to scroll back down to the “Software Downloads” tab, which will have been expanded, and should appear as it does below.

Download and install the client appropriate to your machine’s operating system and hardware platform. Once you have completed that, launch Network Connect. You will be greeted by a blank page. That is to be expected. In the form field labelled “Sign-In Page,” fill in “vpn.wmich.edu,” as is shown in the image below.

This will bring you to a sign-in page, shown below.

Sign into this page using your BroncoNet ID and password. You may be prompted to approve a Juniper Networks program making changes to your system. Allow it to do what it wants. Finally, when you are connected, you will see a window that displays connection information. It should look something like the image below.

At this point, you are successfully connected to WMU’s Virtual Private Network, and can access network services that are not open to the world.
