SSH port sharing
SSH Passthrough sessions and/or Avocent Session Viewer sessions can be shared to allow other
users to view the session data. You can also enable hub/spoke forwarding to allow sessions from
multiple DSView 3 servers to be shared simultaneously. The first user to open an SSH Passthrough
or Avocent Session Viewer session has read/write access; all subsequent users who share the
session have read-only access. Users can enter a command to obtain read/write access, but only one
user at a time can possess read/write access.
To configure SSH Passthrough port sharing:
1. Click the System tab.
2. Click DSView Server in the top navigation bar.
3. Click SSH Passthrough in the side navigation bar. The SSH Passthrough Properties window
opens.
4. To enable shared SSH Passthrough sessions, select the Enable Port Sharing checkbox.
5. To allow simultaneous shared SSH Passthrough sessions from multiple DSView 3 servers,
select the Enable Hub/Spoke Forwarding checkbox.
