5. Server Administration (just:in Engine Linux v1.0)



Overview

On the just:in Engine Linux server appliance you can find:

  • The basic Linux installation (centOS)
  • Video card driver (AJA or Blackmagic)
  • just:in Engine (TOA Media Engine = tme)
  • just:connect (tjc)

just:in Engine Linux and just:connect start automatically when the Linux system has been booted. If they are configured properly they can immediately communicate with a just:in User Interface.

User and Password

The system can be accessed with following credentials via ssh.

User: justin
Password: justin

ssh justin@IP-ADDRESS

Network Settings

By default both network ports are set to DHCP (also the IPMI port is set to DHCP).

Blackmagic Firmware Updater

Only update the Blackmagic driver if you have issues with the system.

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

BlackmagicFirmwareUpdater status

No Firmware update is required if all inputs display the status ok. If the status is not ok use following command to update the firmware. Restart the system afterwards.

BlackmagicFirmwareUpdater update [device]

just:connect Configuration File & Logs

just:connect stores all Channel related information (settings, presets…) in this file:

/var/justconnect.txt

Delete this file if there is a major problem with the system. After deleting this config file just:connect has to be restarted.

Logs

just:connect saves log files. There is log file for each just:connect start and for each Channel. It can be found here:

/var/log/justconnect
