Faster, more responsive kernel (if stuck on an LTS for everything else) : https://liquorix.net/#install
Get or compile https://github.com/qca/open-plc-utils in particular `plcstat`
For some reason it only reports devices other than the one connected to, so you will need at least two machines to monitor the whole network, and it has to be run as root.
So I have two root crontab's that sync to the same place the results of `....plcstat -i wlan0 -t` which looks like
If you look around, everyone make it complicated. It isn't.
* Settings > Hardware > Keyboard
Select the correct keyboard modal, then on the Layouts tab add a new one for your language, layout, and select the 'type 7' variant.
Move it to the top of the list so it's default.
Enable nothing in the 3rd Advanced tab
* Reboot - you should find the volume and power keys work
Edit This no longer works on the latest firmware because the calls are now encrypted. It's trivial to reverse with the AES key just being based on timestamp, but there is an easier way :
Monitoring Powerline speeds ( TP-Link TL-WPA8630P, TL-PA8033PKIT, AV1300)
Firstly, you'll need to use your web browser's network debug panel to intercept a login request to the access points web GUI.
You'll want to find the 'Basic admin' cookie.
Just got a Raspberry Pi3 and a bluetooth keyboard and annoyed that the media keys for doing things like change the column don't work ?
Just add these to ~/.config/openbox/lxde-pi-rc.xml after all the other <keybind> before the </keyboard>
To to find your IP :
alt-f2, lxterminal
ifconfig

Quick note on these PowerLine devices.
They don't need any tools to manage them, as they have a sufficient web interface.
BUT - these devices are terrible network citizens.
The following script outputs the percentage of each ink tank from an Epson XP-312 313 or 315 series WiFi enabled printer.
The output looks like
K:96 C:80 M:12 Y:34
which is perfect for feeding into Cacti or other monitoring systems. Guess I'd best go get some magenta ink !
tl;dr important stuff all works. Minor stuff like finger print scanner easily fixable
The hardware is 'certified' by Canonical but this is meaningless because it doesn't say what of the many options Dell offer for the E5430 was used. It also doesn't list correct details for hardware such as Bluetooth, or even that the finger print scanner exists. And there is no way to submit fixes. And the contact us page is 404 compliant. So let's hope Google finds this for you instead :-)
For a long time, it's been recommended to set up Linux's logrotate system to manage the size of cfserver.log, which can easily grow to be a very large size on production systems, and ColdFusion seems unable to manage itself, unlike the other logs.
I recently discovered however, that a restart of ColdFusion via logrotate was changing the way files were written and read.
