Preemption
Your SSH session may be interrupted or disconnected based on the appliance preemption
levels. If the appliance supports DSView 3 software preemption levels, then user preemption
rights will be determined based on the preemption levels set in the DSView 3 software. For
more information, see Preemption Levels on page 46.
Logging in with a User SSH key
A user SSH key may be used instead of a password to authenticate the user before establishing
an SSH Passthrough session. See User SSH key on page 268 to configure the key.
Establishing an SSH Passthrough connection to a unit
To establish an SSH Passthrough connection to a target device or appliance console:
NOTE: If you are using the Linux or Unix SSH command, you will need to specify the port by entering -p and the
port number. The default port number is 4122. For more information or to change the port number, see Enabling
SSH Passthrough on page 224.
1. To connect to a target device or appliance console, open your SSH client and enter the
following values in the provided text fields:
• <zone1/username>:
Specify the highest level zone for which you have access rights. If a zone is
not specified for the username, the top level zone is assumed. If you do not
have access to this zone, the connection attempt fails.
• <zone2/targetdevicename>@ (to connect to a target device)
-or-
<zone2/appliancename>@ (to connect to an appliance console)
If the appliance resides in a zone below your highest level zone, specify a
zone. If a zone is not specified, it is assumed that unit belongs to the zone
specified for the username. If the unit does not reside in this zone, the
connection attempt fails.
• host name or IP address of the DSView 3 server
NOTE: If DS Zones are not enabled, you do not need to specify a zone for the username or appliance. For more
information about zones, see DS Zones on page 249.
To connect to a target device using the Linux or Unix SSH command, enter a
command in the following format:
<zone1/username>:<zone2/target device name>@<host name or IP address of
DSView 3 server>
