Overview

The just:in linux appliance ships preinstalled with the following components:

• Minimal CentOS installation (CentOS 7.x)

• Video card driver (AJA)

• just:in linux engine (TOA Media Engine = tme)

• just:connect (TOA just:connect = tjc)

just:in linux engine (tme) and just:connect (tjc) start automatically after the OS boot process. If they are configured properly, both services can communicate with the macOS-based Just Control application immediately.

Deployment

The just:in linux appliance comes preinstalled with CentOS 7.9 (2009).

User and Password

The system can be accessed with the following credentials via “ssh”.

Network Settings

By default, the “em1 Ethernet interface” is set to “DHCP”, and the “em2 Ethernet interface” comes configured with a static IP Address (172.17.17.10/24). The “IPMI” port is set to “DHCP” as well.

Open

When connected to the just:in linux appliance via “ssh”, the IP addresses can be displayed with one of the following commands:

or

The IP address for the “IPMI” port is shown at startup, when there is a monitor connected to the server via the “VGA” port or the address can be displayed with the following command, when connected via “ssh”:

IPMI (Intelligent Platform Management Interface)

As mentioned above, the server can also be accessed via the “IPMI” port. Open a browser and enter the “IPMI IP Address” (Username: ADMIN, Password: will be provided upon request).

Blackmagic Firmware Updater

In some situations, the Blackmagic Design video card device needs a Firmware update. Verify if the card is working properly with the installed driver version by using the following command:

No Firmware update is required if all inputs display the status “ok”. If the status is “not ok”, then use the following command to update the firmware. Remember to restart the system afterwards.

just:connect Configuration File & Logs

Config File

just:connect (tjc) stores all Channel related information (Channel settings,Presets, etc.) in the following configuration file:

Delete this file if there is a major problem with the system. After deleting the config file, the “tme” and just:connect (tjc) services must be restarted.

Logs

just:connect (“tjc”) saves log files for each recording channel independently. There is a log file for each just:connect start and the just:connect log files are located at:

The just:in linux engine (“tme”) saves logs files for each channel as well. These log files are located at:

Restarting the just:in linux engine and just:connect service

With the following commands, the just:in linux engine and/or the just:connect service can be restarted:

just:in linux engine

just:connect

Both just:in linux engine and just:connect:

The tme status script

To get an overview of the server and the currently running processes, there is a “tme” status script available, which provides information such as system information, running processes, internal RAID state, AJA driver, etc. Run the following command to execute the “tme” status script:

The output will look like this:

Automatic Server Restarts

If the services should be rebooted automatically, a cronjob has to be activated. This can be done with the following command with “root” privileges:

This command restarts the services (“tme” and “tjc”) every day at 2 A.M. (02:00h).

Daylight saving time

The typical implementation of DST is to set clocks forward by one hour in the spring (Summer Time) and to set clocks back by one hour in autumn (Winter Time) to return to standard time. This could affect recording workflows when working with Computer Time as the Timecode Source and especially when working in Schedule Mode and NTP synchronised setups.

To get the correct new time applied to the recording engine, the services (“tme” and “tjc”) have to be restarted. Thereafter, restart the Just Control client application as well. Please note that by restarting the recording services, any ongoing recording will be stopped. Therefore, we recommend stopping recording manually before restarting the recording services.

Software Updates

Please contact your local ToolsOnAir VAR or the ToolsOnAir Support Team directly, by creating a support ticket, if you want to update your just:in linux appliance.
