Getting Started Using HPC Cluster

How do I login to the cluster?

To login to the cluster, establish a secure shell connection to the login node using an SSH client from a computer with a Case network IP address. Unsecured telnet will not work. Connections from off-campus computers and wireless connections will work only if a Case IP address proxy is obtained via VPN. Once you are connected, type your cluster ipaddress, username in response to the "login as:" prompt, and type your password in response to the "Password:" prompt. Press the "Enter" or "Return" key after each entry. For more info go to http://www.cc.iitm.ac.in/?q=node/76
