Using SSH
Direct login to the A*CRC systems from within A*STAR network can only be executed using Secure Shell protocol (SSH). SSH includes scp and SFTP for file transfers between hosts.

The X Window System (also known as X11, X or X-Windows) is a computer software system and network protocol that provides a basis for graphical user interfaces (GUIs) and rich input device capability for networked computers. It is a requirement for most graphical UNIX and Linux applications.

All host machines have login names identical to their main system name.

To access them use the host name followed by the a-star.edu.sg domain address:
[host_name]@acrc.a-star.edu.sg.

For example to access axle use: ssh [user_name]@[host_name].acrc.a-star.edu.sg
