[SOLVED] I have to keep re-installing a program after every reboot.

I have an home automation controller that connects through the serial port on my motherboard. I managed to get it to work just fine but noticed after every reboot the program wouldn't work again.

The program in question is called "BottleRocket" and it is available through software manager. I've re-installed through there, uninstalled and re-installed through synaptic, and it's always the same outcome; works great, but no dice after reboot.

As best I can tell, the culprit is a link file called "firecracker" that gets copied to the /dev/ folder. For some reason it always
vanishes s after a reboot and the commands associated with the program wont work.

Any ideas?

Thanks!

Quick search found this, which looks like your problem. The Debian reference gives a solution, so try this (untested)

Code:

sudo echo 'KERNEL=="ttyS0", SYMLINK+="firecracker"' > /etc/udev/rules.d/98-firecracker.rules

This only (ever) needs to be run once after a reboot, then you should be good to go - just reboot again and see if it fixes the problem.

Wow it worked! I was getting some permission errors so I had to use the following code:

Code:

echo 'KERNEL=="ttyS0", SYMLINK+="firecracker"' | sudo tee /etc/udev/rules.d/98-firecracker.rules

Thanks again for your help!
