Ubuntu Linux agent instructions

  • On Ubuntu (and Mint and other Debian based Linux distros), you should install the agent like this:

    Do this while logged in as your user (not root), in a Terminal window:

    sudo apt-get -y update
    sudo apt-get -y upgrade
    wget https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_amd64.deb
    sudo apt install ./triggercmdagent_1.0.1_amd64.deb

    If you're in X-Windows, type:


    If you're not in X-Windows, run one of these 2 commands instead (depending on your specific OS):

    node /usr/share/triggercmdagent/resources/app/src/agent.js --console
    node /usr/lib/triggercmdagent/resources/app/src/agent.js --console  (newer Ubuntu OS's)

    Log into your triggercmd.com account, and copy the token from the Instructions link, and paste it into the Token prompt.

    Then to install the background service:
    If you're in X-Windows: Right-click T tray icon, click Background Service - Install Background Service
    If you're not in X-Windows, CTRL-C out of the above "agent.js --console" command, and run:

    sudo sh /usr/share/triggercmdagent/resources/app/src/installdaemon.sh
    sudo sh /usr/lib/triggercmdagent/resources/app/src/installdaemon.sh  (newer Ubuntu OS's)

    To check the status of the background service:

    • Run: systemctl status triggercmdagent
    • In your triggercmd.com account, click View Triggers. If you see your background triggers, the background service is working.

    If at first the background service doesn't install, try this:

    • CTRL-C, or select Quit from the T tray icon.
    • Re-run triggercmdagent
    • Try installing it again using the tray icon.

    To upgrade see Upgrading the Linux agent on Ubuntu

    EDIT 6/4/18: For Ubuntu 14 you'll have to install using this method instead:

    sudo su -
    wget https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_amd64.deb
    dpkg -i ./triggercmdagent_1.0.1_amd64.deb
    apt-get install -f

  • Working without problems on Centos 8 minimal installation.

  • @Russ Not working for me. I did all your steps, but I am getting this on final check:

    alt text


    And it was server when I installed base system for VM, but after all this command, it turn to GUI and can't open terminal anymore.

  • @pirates, please try this. Switch to root with this command:

    sudo su -

    Run this:

    node /usr/lib/triggercmdagent/resources/app/src/agent.js --console

    It should prompt for your token, then start running. If it does, CTRL-C, then restart your triggercmdagent daemon with this command:

    systemctl restart triggercmdagent

    You can also watch the full log for the agent in another window with:

    journalctl -u triggercmdagent -n 100 -f

    Please send me any errors you see.

  • @Russ I will try but why is it switching to GUI version of my install from headless I had initially?

  • @pirates, are you saying you installed Linux without the X-Windows GUI, then when you installed the TRIGGERcmd agent it installed X-Windows with it?

    If that's the case, I'd like to try to reproduce that. What Linux are you using?

  • @Russ I am using ubuntu server 20.4 on proxmox vm to test. And yes from server to x-windows.. tried twice and happened both time.

  • Thanks @pirates. I'll try to reproduce and see if I can fix that. I suspect the agent depends on a package that depends on X-Windows, so it automatically installed X-Windows.

    In the meantime, you could disable X-Windows at boot.

    EDIT: @pirates, I reproduced the issue. I had a non-GUI, no X-Windows Ubuntu 20 VM, then installed the agent and it installed X-Windows. I'll get back to you soon because there should be a way to run the agent as a background service without X-Windows, like you can on a Raspberry Pi.

    EDIT2: @pirates, this procedure worked for me to install the background agent without X-Windows:

    sudo su -
    git clone https://github.com/rvmey/TRIGGERcmd-Agent.git
    cp ubuntupackage.json package.json
    apt install -y npm
    cd /root/TRIGGERcmd-Agent
    npm install
    node /root/TRIGGERcmd-Agent/src/agent.js --console
      (enter your token, then press CTRL-C to exit the foreground agent)
    /bin/sh /root/TRIGGERcmd-Agent/src/daemonmgr.sh --add /root/.TRIGGERcmdData
    systemctl enable triggercmdagent
    systemctl status triggercmdagent

    I copied these instructions to a new article here.

  • I will try as soon as I get some free time and I will get back to you. Thanks for reply.

  • Is this normal?

  • @pirates, to avoid that problem, copy the ubuntupackage.json file to package.json before you run npm install. I'll update the steps above with that. It looks like the default package.json was the Windows version.

  • @Russ I have this installed and functional on a Debian 10 Raspberry Pi. The default commands work great, as well as a custom one that triggers a bash script that sends a WOL command to my PC.

    Question for you: Does triggercmd run the script as root, or as the user with elevated privileges via sudo?

  • @Tim-Manochehri, it runs them as root. If you run this command you'll see that the agent runs as root, and the agent runs the commands:

    ps -ef | grep triggercmdagent
