Before everything, please note:
- This is a tech doc only for Pros. Incorrect scripting may cause system corruption that you may have to reset factory default or even reflash the disk.
- This is for Firewalla Gold only.
- This is for version 1.971 or above
Customized Scripts
You can add some scripts to Gold so that it can be automatically executed when Firewalla service restarts (for example, when Gold reboots or software updates).
These scripts can be placed under this folder: (create this folder if not exists)
/home/pi/.firewalla/config/post_main.d/
Any files ending with ".sh" will be executed. For example:
/home/pi/.firewalla/config/post_main.d/hello.sh
Note: please make sure your scripts can be executed multiple times at unscheduled time because it will be called every time Firewalla service restarts.
Examples: Install package "iftop"
sudo apt-get update
sudo apt-get install iftop -y
Customized Cronjobs
To create scheduled jobs, you may add your own cronjob by putting cronjob expression in this file. It will be incorporated to the system crontab when Firewalla service restarts.
/home/pi/.firewalla/config/user_crontab
Example:
pi@firewalla:~ (Firewalla) $ cat ~/.firewalla/config/user_crontab
* * * * * /bin/bash -c "date" &> /tmp/date.log
You can verify if it's incorporated by running "crontab -l"
Examples: TBD

I have blue and am just interested in persisting some crontab settings. Will the
file also work for Firewalla blue? Thanks.
There is no need to do this for the blue, you can just use cron directly. The reason gold is a bit special is, when in router mode, we want it to be stable, hence we restrict access to services to prevent 'you' from messing up the operating system and shut down the network.
Hmm. Ok, I'll let you know if I loose my crontab next time the router reboots. I thought that is what happened before.
Another use for custom scripting. Install Speedtest CLI on Firewalla.
Want to have speedtest cli on Firewalla Gold? This will tell you how fast your internet connection is right on Firewalla (no wifi or Ethernet involved)
Firewalla will remove anything installed after upgrades so you can install a script to reinstall for you after firewalla upgrades and possibly reboots. See this gist.
Then you can run speedtest.
Or
if you have dual WAN and want to test WAN2
How soon after adding an entry into the ~/.firewalla/config/user_crontab does the main crontab pickup the change?
after rebooting. @theoninhunter.
@Michael Bierman
Yep that did it many thanks!
Will scripts wait to be called until after a network connection has been made or does that need to be custom coded in the script?
