HP-Supported Open Source pdsh Options | HP UX System Adstration

A HP-Supported Open Source pdsh Options

This release of DSAU includes open source pdsh code that was compiled with the following options:

•readline support.

•The secure shell (ssh) remote command module (pdsh —R ssh).

•The remote shell (rsh) remote command module (pdsh —R rsh).

Because of security concerns, this option is disabled by default at installation time. For information on Parallel Distributed Shell, see the Chapter 4 (page 83) chapter.

•The machines module (pdsh —aoption).

The command pdsh —Vprovides a summary of the options, and pdsh —Llists details on each module.
