Access services

The first thing you have to do in this landing is to connect to the GPI servers. 

The basic information to connect to our servers is:

• Server / Host: calcula.tsc.upc.edu
• SSH Port: 2228
• Credentials (user/pass): Use your TSC credentials.

You have two main ways to connect to our server: Terminal only or with a Graphical interfaces available.

Terminal (SSH)

Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, rendering them susceptible to packet analysis. The encryption used by SSH is intended to provide confidentiality and integrity of data over an unsecured network, such as the Internet.

Linux and Mac use to have a ssh-client out-of-the-box. Just open a Terminal application and type the following command replacing username by your actual username:

>> ssh -p2228 username@calcula.tsc.upc.edu

If you are at the UPC or you have a really good internet connection you can use X11-Forwarding by:

>> ssh -X -p2228 username@calcula.tsc.upc.edu

If your laptop is Windows, then the recommended option is to install Mobaxterm as a terminal, open a local terminal and type the above commands.  Here you have a basic tutorial for Mobaxterm. For downloading or uploading files to the server, you can use FileZilla on Windows, Linux and macOS. Here you haver a basic tutorial for FileZilla.
