VPN Frequently Asked Questions

How do I access VMs in the Big Data Lab?

Unless you are on a Hofstra lab computer in Adams Hall, Weed Hall, Weller Hall, or C.V. Starr, you first need to connect to the VPN. To connect to the VPN from your laptop or home computer, you need to install an OpenVPN client and obtain a client profile from csconnect.hofstra.edu. In the Open Access Labs (Hammer and Calkins), you must instead use the Cisco AnyConnect Secure Mobility Client and connect to csvpn2.hofstra.edu.

Once connected to the VPN, follow these directions and use the vSphere Client or OpenNebula to access your VM.

How do I access Big Data Lab VMs from Hofstra lab computers?

Adams Hall, Weed Hall, Weller Hall, and C.V. Starr:

A VPN connection is not needed to access VMs on Hofstra lab computers in Adams Hall, Weed Hall, Weller Hall, and C.V. Starr, except for VDI labs.

Hammer and Calkins Labs (Open Access Labs):

To access VMs from the Open Access Labs, please open the Cisco AnyConnect Secure Mobility Client and connect to csvpn2.hofstra.edu. When prompted, enter your username as “students" followed by you portal username, e.g. students\h702345678.

Why can’t I access my virtual machine from the Hofstra network?

You need to use the VPN throughout the campus to access VMs in the Big Data Lab, except in Adams Hall, Weed Hall, Weller Hall, and C.V. Starr. Also, a VPN connection is needed to access VMs from any device connected to eduroam, even in one of the aforementioned buildings.

It does not accept my username and password! How do I login?

Please make sure you are using the correct network credentials. For csconnect and OpenVPN, you must provide your network id without “students" at the beginning (e.g. h702345678 or tstude4) or the username part of your pride email address. For the Cisco AnyConnect Client, you must enter your username as “students" followed by your network id. The password is the one you use for the my.hofstra.edu portal, not the one for your Linux account. For more information, please see this.

What do I do with the file I just downloaded?

Once you have downloaded the .tar file, you must use a program such as 7-Zip or WinRAR to extract its contents. On Linux, run the command tar -xvf profile.tar to extract it. Once extracted, you need to open the .ovpn file with the VPN client or move it into the correct folder. If you haven’t already done so, first install the appropiate VPN client software.

  • For the OpenVPN GUI on Windows, move the .ovpn file into the directory C:\Program Files\OpenVPN\config.
  • For the OpenVPN Desktop Client on Windows, double-click the .ovpn file to import the profile.
  • On Linux, run the command: sudo mv profile.ovpn /etc/openvpn/client.conf.
  • On Mac OS X, double-click the .ovpn file to open it with Tunnelblick.

Where do I need to use the VPN?

A VPN connection is required to access the Big Data Lab from off-campus and throughout the campus, except from lab computers in Adams Hall, Weed Hall, Weller Hall, and C.V. Starr. This means you must use the VPN to access the Big Data Lab from the Open Access Labs and Dorm rooms. Please note, you do not need to use the CSVPN if you have access through HUVPN.

Who may use the VPN?

The VPN is for majors or minors in Computer Science, students in Information Systems & Business Analytics (ISBA), and faculty.

Help! I can’t get the VPN to work.

Please refer to the troubleshooting tips on the help page.

How does this relate to faculty VPN access?

The Computer Science VPN is completely separate from the Hofstra IT VPN. If you have access through HUVPN, you do not need to use the CSVPN. Please do not use the OpenVPN client in conjunction with the Cisco Unity Anyconnect client. (Even if this works, it is an unsupported configuration.)
