To keep my data backed up savely I rely on CrashPlan. For the last weeks I had a quite long bug request pending. What I took from it, was the problem CrashPlan had when the network is not yet available when the service is started. Therefore I disabled its automatic startup and wrote a dispatcher script for the NetworkManager to automatically start crashplan, whenever I get a network connection and stop it, when the connection breaks down. Find the script here: 02crashplan.sh
During mmy research I found out, that the dispatcher service was not enabled on my Arch Linux system. That’s important for the scripts to work.
$ sudo systemctl enable NetworkManager-dispatcher
Similarly the service for the modemmanager was disabled, which caused my UMTS card to not work.
$ sudo systemctl enable ModemManager
While working on this, I wrote another dispatcher script, which takes care of connecting to the univeristy vpn (works for all Munich universities, which get their internet services from the lrz) automatically, when I connect to the corresponding network. Find the script here: 01lrzvpn.sh
The idea for this script and its frame is taken from Ubuntuusers.de. Make sure, to save your credentials in the corresponding VPN configuration file and update the name of the VPN in the script to the one you are using.
