Title: Help to put custom jobs in CRON
Post by: vsta on January 22, 2021, 08:05:50 pm

Hello,

I'm a brand new user here with a brand new OPNsense box running on a Lenovo ThinkCentre m92p. And so far, so good. A bit faster speed, and ability to remove quite a bit of ads.

I have a concern that needs to be addressed and hope that I can get help from here.

I have a requirement to either:
 1. Scale down the internet connection speed considerably (i.e.: analog modem speed) then scale it back up to normal at certain time of day.
 2. Come to worse if the above is not achievable with OPNsense then I can just bring down/up the pppoe interface again at certain time of day.

For option (1), I've created a pipe that applied to the whole network, which works beautifully, however I couldn't find a way to schedule it!

For option (2), I've tested and it works well with the command [ifconfig pppoe0 down/up], and I can manually put it to cron from the terminal, but I'd like to have that in the cron interface

I hope that you can help me to get either one of those done, I'd greatly appreciated.

Many thanks in advance

For (2), add a new configd action as per this: https://docs.opnsense.org/development/backend/configd.html

If you include a description field in the action (such as description:Take PPPoE down) it will be appear in the cronjob list after running service configd restart

Use the full path for the command. If you need something more sophisticated than a single command, put a script in /usr/local/sbin and call that

Re 1:
you should look into ipfw command and use chron to call ipfw with an appropriate configuration.
The default config file for ipfw on OPNSense is: /usr/local/etc/ipfw.rules

The config file is called as ipfw -q /usr/local/etc/ipfw.rules

So: make a copy of ipfw.rules, change pipes as you fit, and call ipfw -q <config> from chron

Thank you @Greelan, that works very well, and which I've done. Things work perfectly.

@mihak, I guess there's no direct way to that. I'll try to implement the in-direct way from your suggestion. Will keep you posted.

Again, many thanks
