SSH Passthrough Sessions
14
221
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 serial
unit managed by the DSView software that supports Secure Shell 2 (SSH2) and Avocent DS
Authentication 2 Protocol (ADSAP2) protocol.
The DSView 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
DSView servers. Serial sessions initiated from the DSView 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 DSView server is no longer available, a
user may establish an SSH Passthrough session to a different DSView server.
Configuring SSH Passthrough
• Enable the SSH server; see Enabling the SSH server on page 211.
• Enable SSH Passthrough; see Enabling SSH Passthrough on page 222.
• (Optional) Enable SSH port sharing; see SSH port sharing on page 223.
Only DSView software administrators may enable the SSH servers, SSH Passthrough and SSH
port sharing.
