How to connect to a Linux machine over the Internet?

Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols such as the Berkeley rlogin, rsh, and rexec protocols. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. (extract from Wikipedia)

SSH is the preferred protocol to connect to CISE Linux systems over the Internet.

In order to ‘ssh’ into a CISE system you need a SSH client. Different SSH clients are available for different platforms. We recommend to use the native ssh application on Mac and Linux systems, and PuTTY on Windows.

Please Note: Due to an increase in brute force attacks against the CISE network, many of our machines now run firewalls to prevent repetitive failed connections. If a machine stops responding to your ssh requests, please wait for a minute and try to connect again.

How to connect to a Windows machine over the Internet?

Remotely accessible CISE Windows Systems are available via Remote Desktop Protocol (RDP).

In order to 'rdp' into a CISE system you need a RDP client. The Windows native application Remote Desktop Connection is the recommended application for Windows users. Remmina is the preferred client on Ubuntu systems.

Please Note: Due to an ongoing attack against UF’s network, all RDP traffic from the Internet is being block by our external firewall. In order to use RDP remotely, you must be connected using UF VPN Service.

How to connect to UF VPN Services?

The Gatorlink VPN service provides secure remote access to the University of Florida network and makes it appear as if your computer were physically attached to the campus network. All instructions on how to use the service can be found on the UF IT Wiki.

The Gatorlink VPN service is provided by UF Network Services and the UF Helpdesk.
