Viewing and customizing the SSH server settings
To view and customize the SSH server settings:
1. In a Units View window, click on the appliance name.
2. Click Appliance Settings, click Data Logging and then Syslog SSH Server in the side
navigation bar.
3. In the DSView Server IP field, enter the IP address for the DSView 3 server that will receive
data logs. This may be either the hub or a spoke server.
4. In the Syslog Server Port field, enter the Syslog port that you set in Enabling and disabling the
Syslog server on page 169.
5. In the SSH Server Port field, enter the SSH port that you set in Enabling and disabling the SSH
server on page 169.
NOTE: It is recommended that no more than 2048 data logging and SSH Passthrough sessions be
open concurrently.
6. The Appliance Configuration Section contains several fields for managing the SSH sessions
and buffer warning events. Each field contains the Avocent recommended value, but you may
change these values if needed.
• SSH Idle Timeout (seconds): If the SSH session is inactive for the specified amount of
time, it will be closed. The default time-out is 15 seconds.
• SSH Start Threshold (bytes): The appliance will log data in its local memory. Once it
meets the threshold specified in this field, it will attempt to open an SSH session to the
DSView 3 server. The default threshold is 10 KB.
