Secure Connections

OS X has ssh, scp and rsync built-in. Command line Terminal is in Applications → Utilities.

Filezilla is a GUI program for both SSH File Transfer or SFTP. Install using your distribution's software manager or download from filezilla-project.org. Lauch the program, choose File > Site Manager > New Site. Configure SFTP connection to gauss:

Protocol: SFTP - SSH File Transfer Protocol
Host: math.dartmouth.edu
Logon Type: Ask for password
User: your username on gauss

Click OK to save configuration or Connect to save and connect at once.

VPN

Dartmouth currently uses GlobalProtect VPN. See VPN in ITC knowledge base.

Math VPN uses OpenVPN technology. Search for and install OpenVPN client app for your device (available for Android, Chrome OS, iOS, Linux, macOS, Windows). Download MathVPN.ovpn configuration file. Use your OpenVPN app to add a new VPN configuration by importing the downloaded MathVPN.ovpn. The file has embedded certificates, so there is no need to provide them separately in VPN configuration.

When starting MathVPN connection use your “gauss” login credentials.

If the app doesn't offer a way to import configuration files, here are MathVPN parameters for manual configuration:

VPN type: OpenVPN
Gateway or portal: 129.170.28.58
Authentication: use your “gauss” username and password
CA certificate: DigiCertCA — may already be present on your device (in /etc/ssl/certs/ on Linux) or download.

Math Email

If you have Math Dept. user account (also known as “gauss” account), you also have a corresponding email account. Your Math email arrives at (and can be sent from) math.dartmouth.edu server. It can be accessed instantly and globally via Webmail — this does not require any configuration! As for email applications, all of them, including mobile, can be configured to use your Math account using these generic settings:

Incoming server: math.dartmouth.edu, type: IMAP, port: 993
Connection type/encryption: TLS
Username: your Math username
Password: for the username above
Outgoing/SMTP server: math.dartmouth.edu, port: 465, protocol: TLS; authenticate with Math username and password.

Please use plain text to write email whenever possible (useplaintext.email), thank You!
