How do I log into the cluster?

Most of the cluster resources are on a private, internal network. So access to the cluster is via one (or a few) node(s) that also have connections to the campus’ public network. Currently, the node that is available for interactive use is: submit.urc.uncc.edu

The supported methods for connecting to this node are:

Secure Shell (SSH) - For secure remote login
Secure Copy (SCP) or Secure FTP (SFTP) – For secure data transfer.

Most common Unix or Linux operating systems (including Mac OS X) come equipped with client versions of these programs for use from the command line. For more information refer to the man pages: ssh, scp, sftp (these are for the Redhat Linux clients – other Unix or Linux systems should be similar but may not be identical).

There are also various commercial and shareware versions of these commands available for MS Windows. One popular free client is available from ssh.com

The cluster uses Kerberos for id management, so users should use the Kerberos command kpasswd to change their password (instead of the UNIX passwd command). kpasswd should be in the user’s command path so simply typing kpasswd on the command line will prompt for old and new passwords. All users should change their passwords during their first interactive session.

In addition to kpasswd, the user can also change their password when logged into the ChargerNet Portal by clicking on the “Change Password” link in the Utilities menu.
