Accessing TAMU Supercomputing Machines
Users should use a SSH client to log in to our machines. Unencrypted methods such as telnet, rlogin, and XDM are NOT allowed for accessing our machines. Any SSH client will typically require the user to supply the name or IP address of the machine to which access is sought, as well as a username and a password, before granting access. The interface may differ from platform to platform (PC based clients typically have GUIs while Unix based clients may not).
SSH (Secure SHell) clients provide essentially the same functionality as telnet clients but encrypt network traffic between the user's machine and the remote machine. SSH is therefore secure against snooping and is the recommended method of connecting to our machines. SSH clients may not be installed by default on all systems but many free implementations are available for download from the Internet.
You should also get into the habit of using secure copy (SCP -- a companion program often bundled with ssh) instead of the traditional ftp utility to transfer files. SCP is more flexible than ftp in that it allows you to transfer directories from one machine to another in addition to just files. There are SCP graphical user interfaces for Windows and for Macs.
If you wish to run programs with graphical interfaces on one of our machines and have it display on your workstation, you will need to have a X11 server or X11 server emulator running on your workstation.
Instructions for using SSH, SCP, and a X11 server with our systems are listed below for each operating system:
