Connecting to NERSC

Remote connections to NERSC machines are made over the internet. There are no dialup modem lines at NERSC.

All NERSC computers (except HPSS) are reached by by use of programs that implement the Secure Shell (SSH) communication and encryption protocol, version 2.

Mass Storage systems must be accessed differently. See the HPSS pages for those procedures.

For security reasons, all network ports into NERSC systems are blocked, except for those running SSH services. For that reason, ftp "tunneling" is not available for file transfers. If you have a need for incoming port access, please contact the NERSC consultants.
