About the Grid Plug-in Protocols

The grid plug-in supports three protocols. You must select run and copy commands for each protocol.

The SSH Grid plug-in supports the following protocols:

  • Ssh and scp (Open SSH). Select these protocols to dispatch the OS Command from a local Linux system to a remote Linux system, whenever security has to be maintained (e.g., when crossing a firewall). Secure Shell (Ssh) is a remote login protocol that uses public-key encryption to authenticate users and to secure their login sessions. Secure Copy (scp) is the corresponding file-transfer protocol. Open SSH is a commonly-used open-source implementation of these protocols.

  • SSH and scp (PuTTY). Select these protocols to dispatch the OS Command from a local Windows system to a remote Linux system, whenever security has to be maintained (e.g., when crossing a firewall). PuTTY is a commonly-used open-source implementation of the ssh/scp protocols made specifically for Windows.

  • Rsh and rcp. Select these protocols to dispatch the OS Command from a local Linux system to a remote Linux system, whenever security is not a concern (e.g., when both are behind the same firewall). Remote Shell (Rsh) and Remote Copy (rcp) are standard remote login and file-copy protocols that are available on all Linux systems (except where deliberately removed or replaced). These protocols are fast, but they are not secure.
