== Connecting
To connect to the Math department network from outside of Cornell, you will need to use the Cornell VPN. In particular, you will need to connect to the Math Department network through the Cornell VPN.
First, you will want to install the Cisco AnyConnect client, as provided by Cornell IT. Follow this link and get the VPN software installed on your machine.
Next, you will need to have the math.vpn permission permit. We usually add people automatically to this permit when they join the department, but it may have been overlooked. You can check this by going to your Math account control panel, and down near the bottom of the page it says "You have these Math permission permits:" Make sure math.vpn is listed. If it is not, contact a Math sysadmin or administrator to add you to that permit.
Now that you've got both of those completed, when you log in to the CU-VPN software, where you normally put in your NetID, you will put in your NetID followed by @math.vpn. This looks very strange but it tells the system to connect you to the Math department network in addition to the rest of Cornell. For example, if your netid is xyz123 then in the login section enter your netid as xyz123@math.vpn
and enter the rest of the login details as usual. When you connect to the VPN you will be prompted for Cornell two-factor login. Once the connection is complete, your computer can connect to the Math department machines.
== Connecting for Interactive Use ==
=== Graphical Desktop ===
To use a remote desktop on the Math Linux systems, the primary way to do this is to use X2GO. You can download the [https://wiki.x2go.org/doku.php/download:start X2GO client software] here. This software works on Windows, Mac, or Linux. If you are installing the Mac version, you will first want to install the latest version of [https://xquartz.org Xquartz]. For the other platforms, no additional downloads are necessary.
=== SSH Access ===
You can connect to the Math machines using SSH. This is a text-only method, which some people are very comfortable with. For Linux or Mac, you can ssh into a math system with the built-in SSH client that comes with your machine. Open up a terminal window, and type
ssh mortimer@fibonacci.math.cornell.edu
where 'mortimer' is replaced with your Math username, and 'fibonacci.math.cornell.edu' can be any one of the Math linux machines.
You'll be prompted for a password, and then you'll be logged in.
For Windows machines, you will need to download the PuTTY SSH Client. Once you have that downloaded and installed, you can run PuTTY and enter the username and hostname and log in.
