SSH Passthrough Sessions

167
An SSH Passthrough session is a serial session opened to a unit without the use of a web
browser. From an SSH client, a user with access rights can establish a connection to any PDU
managed by the Rack Power Manager software that supports Secure Shell 2 (SSH2) and Emerson
DS Authentication 2 Protocol (ADSAP2) protocol.
The Rack Power Manager server provides user authentication and, if events are enabled, logs SSH
Passthrough session events. You can also share SSH Passthrough sessions with multiple users
across multiple Rack Power Manager servers. Serial sessions initiated from the Rack Power
Manager client software may also be shared if the Avocent Session Viewer is preconfigured as
the serial viewer.
Shared serial sessions provide server redundancy. If a Rack Power Manager server is no longer
available, a user may establish an SSH Passthrough session to a different Rack Power Manager
server.

Only Rack Power Manager software administrators may enable the SSH servers, SSH Passthrough
and SSH port sharing.
