Access Using SSH
To connect to HPRC clusters, you must use SSH (Secure Shell). SSH is a client-server software that provides for secure (by encryption) logins and other communication between two hosts. SSH is freely available in the Internet for Linux/Unix and PC Windows (in the guise of MobaXterm).
To initiate SSH connection to target cluster's login node from campus, find the hostname and credential (userID/password) info from Table 1 below. For example, connecting to Ada cluster from a MacOS/Linux/Unix operating system, enter:
localhost$ ssh NetID@ada.tamu.edu
where the ada.tamu.edu address is a DNS round-robin alias for ada[1-8].tamu.edu. You will be prompted for your password in order to establish authentication. Once you login into one of the 8 login nodes, the shell's prompt will be NetID.ada[1-8].
|Cluster||Hostname||Number of login nodes||Credential (UserID / Password)|
|Ada||ada.tamu.edu||8 (ada1 ~ ada8)||NetID / NetID password|
|Eos||eos.tamu.edu||5 (eos1 ~ eos5)||Eos_ID / Eos password|
|Curie||curie.tamu.edu||2 (curie1 ~ curie2)||NetID / NetID password|
|Neumann||neumann.tamu.edu||4 (neumann1 ~ neumann4)||NetID / NetID password|
|Crick||crick.tamu.edu||1 (crick1)||NetID / NetID password|
Access from Windows
Using MobaXterm (Recommended)
Access from MacOS
Using the Terminal Program
Find the Terminal program, under Applications->Utilities.
- Select Applications
- Double click the Utilities folder
- Double click the Terminal utility
- A Terminal window will now appear.
Remote Display of Programs with Graphical Interfaces
The recommended X-Windows emulator for Mac OS X is Apple X11, which is available free from Apple.
- After X11 is installed on your system, start Apple X11.
- A xterm window should appear on your screen.
- Login to a UNIX machine (example:
ssh -X email@example.comThe
-Xoption tells SSH to allow programs to forward and display their graphical interfaces. This is known as X11 forwarding.
- To verify that X11 forwarding is working, type the following command:
xtermIf a new xterm terminal window for the remote system pops up, then X11 forwarding is working correctly.
Access from Linux/Unix
For connecting to cluster login nodes from outside the campus, you need to activate Virtual Private Network (VPN) first, then initiate SSH connection to the cluster login nodes. You can find VPN installation instruction from TAMU ServiceNow Knowledge Base page on VPN.
