Secure Shell (SSH) is a network protocol that facilitates secure data exchange between networked devices. By establishing a secure channel between a local and a remote computer, SSH exchanges information securely by using data encryption and message authentication codes.
BNL policy dictates that you use an official SSH gateway to enter the lab network with SSH. To make moving around from computer to computer faster and easier, advanced users may want to put their SSH keys on the gateway [instructions]. That allows you to have single sign-on capabilities.
NOTE: The SSH gateways are not designed for file storage. Transferring large data sets should be accomplished by tunneling.
The Laboratory has several SSH gateways. The addresses to reach the SSH gateways are:
ssh.bnl.gov (main gateway) ssh.bluegene.bnl.gov (Bluegene users only) ssh.pbn.bnl.gov (CAD users only) ssh.qcdoc.bnl.gov (QCDOC users only)
If you are trying to reach the gateways from inside the Laboratory for any reason, the address is:
ssh.sec.bnl.local (main gateway) ssh.bluegene.bnl.local (Bluegene users only) ssh.pbn.bnl.local (CAD users only) ssh.qcdoc.bnl.local (QCDOC users only)
Note: In order to use the SSH Gateway you must have an SSH client installed first. We recommend the latest version of OpenSSH for UNIX users and the latest version of PuTTY for Windows ( command line ) or WinSCP ( GUI ) users. The SSH gateway also supports RSA SecureID and CRYTPOCard authentication. (Note that the CRYTPOCard is being phased out.)
If you have not signed up for an SSH account or an RSA SecureID, call the account management office at Ext. 4444 for assistance.
Instructions for using the SSH gateways
If you need assistance installing the appropriate SSH client contact the helpdesk (x5522).
