Chapter 14: SSH Passthrough Sessions 181
3. If more than one connection exists to the target device, the SSH connection attempt fails and
the DSView 3 software informs the user of the failure reason. To connect to a target device
with multiple connections, specify the appliance name and port instead of the target device
name. The appliance name must be identical to the appliance name in the DSView 3 software
database, and the port must be the exact port number that appears in the Units view in the
DSView 3 software.
To connect to a target device with multiple connections, open your SSH client and enter the
following values in the provided text fields:
• <username>:
• <appliancename>:port@
• host name or IP address of the DSView 3 server
To connect to a target device with multiple connections using the Linux or Unix SSH
command, enter a command in the following format:
<username>:<appliance name:port>@<host name or IP address of DSView 3 server>
4. The SSH client attempts to establish an SSH connection to the appliance or target device. If a
successful connection is established, the DSView 3 server acts as a proxy between the user and
target device.
If an SSH Passthrough session to the same appliance or target device is already open, your
session is shared with the previously connected users. You have read-only access to the
session, but you may enter a command to obtain read/write access. See Transferring read/write
access on page 183.
5. If the console port on the target device requires additional authentication, the user is prompted
to log in.
Escape key sequence
An escape key sequence is a combination of characters that can be sent to the DSView 3 server to
affect an SSH Passthrough or Avocent Session Viewer session. The default escape sequence is
^Ec, which can be followed by an escape key to send a command to a target device. Some escape
key sequences are limited to only the user with read/write access.
In this chapter, the preset escape Sequence ^Ec is used in all examples to indicate the configured
escape sequence.
