How to restrict serial port access to a single session and set time-out on a Terminal Server

This guide explains how to configure a Terminal Server to restrict serial port access to a single session and set the default time-out.

Предпосылки

The Terminal Server must run OS version 24.11.2 or a later version.

For upgrade instructions, refer to How to Upgrade Terminal Server OS.

Это руководство было проверено с помощью встроенного ПО Opengear версии 24.11.2, которая была обновлена с версии 22.06.0 и поддерживается в среде выполнения Nexus Network Fabric версии 5.0.0.

Step 1: Set time-out for sessions

Configure the session time-outs for CLI, WebUI, and Serial Port access using the following commands:

sudo ogcli update system/cli_session_timeout timeout=15
sudo ogcli update system/webui_session_timeout timeout=15
sudo ogcli update system/session_timeout serial_port_timeout=15

[Note] In the above example the timeout value is set to 15 minutes.

Step 2: Verify time-out settings

Confirm the new time-out settings by running:

sudo ogcli get system/session_timeout

cli_timeout=15
serial_port_timeout=15
webui_timeout=15

Step 3: Configure single serial port session

To restrict each serial port to a single session, execute the following command.

for i in {01..48} ; do
  echo "### Configuring single_session on port$i ###"
  ogcli update port port$i single_session=true
done

Примечание.

This process may take approximately 15 minutes.

Step 4: Verify single session configuration

Validate the configuration by listing the ports and checking the single_session status:

sudo ogcli get ports | grep -E 'ogcli get port|single_session'

Alternatively, check individual ports:

sudo ogcli get port "port01"

single_session=true

Repeat the command for other ports as needed (port02, port03, etc.).
