#Raspberrypi

You’ve just updated your Raspberry Pi (or whatever Linux) and you’re noticing your CIFS (smb) mounts aren’t getting auto mounted anymore. You curse and start noticing this error:

# mount -t cifs //192.168.1.100/public -o username=public,password=public sam/ mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

The solution is to add after -o username=X,password=Y the following: sec=ntlm; thus it becomes -o username=X,password=Y,sec=ntlm.

You can do the same in fstab:

In a couple of lines: how to get FR24 (+ dump1090) to work on your Raspberry Pi.

Be sure to have the right hardware: flightradar24.com/dvbt-stick and … obviously … a RPi.

I got a NooElec from Amazon because I didn’t have the patience to wait for something (that might not work) from AliExpress.

As root:

apt-get update && apt-get install cmake gcc pkg-config libusb-1.0 make git-core libc-dev git clone git://git.osmocom.org/rtl-sdr.git cd rtl-sdr mkdir build cd build cmake ../ -DINSTALL_UDEV_RULES=ON make && make install ldconfig cd ../..

Today I’m selling Raspberry Pi’s.

4 are unused, new, in packaging. I have a couple more (about 6) who got used for a couple of hours, but never anything serious.

I am also selling the power adapter and the laser cut casing.

  

Raspberry Pi: €30,49/item (type B - 512 Mb RAM)

PSU: €4.45/item

Casing: €4/item

Possible on invoice.

I got a mail in my inbox about a week ago from Anthony, telling me how to improve my Munin & temp script for a RPi:

Hi,

I just read your (old) blog post about monitoring the temperature of the Raspberry Pi with munin[1].

I had the exact same error as you did when I was trying to let munin do the job all by himself:

temp.value VCHI initialization failed)

It turns out the solution was quite easy: in

CPU temperature from a Raspberry Pi (behind the display, in the wall).

There’s this howto that explains how to set up the RPi as ad blocker.

I’ve two RPi’s acting a router and was already running dnsmasq. I decided to give it a try. Note that this howto can actually be used on any DNS serving Linux server.

First of all, don’t go with the pixelserv as it crashes after a few minutes.

Apache is an option that worked fine. A general hint: if you’re already running Apache or whatever on port 80, just add a 2nd static IP and make Apache listen to that.

Quick hack to get Munin to graph the cpu temperature.

First of all, install Munin and make sure it’s working.

Then follow these steps:

1. We’ll use cron to write the current temp to a log file. We do this because I wasn’t able to get Munin to directly execute the command (error: temp.value VCHI initialization failed)

Execute crontab -e and add this line (this has to be on one line):

This.

Used my Raspberry Pi, with an USB disk as TimeMachine. Another disk as NAS/storage. It’s just quite slow… Not sure whether it’s my WiFi or RPi that can’t keep up.

But for now, it’s working.

I now own three Raspberry Pi’s.

Using two of them (and my Guruplug as WiFi AP) I connected my new apartment with my old house (= parents) over VPN.

This way I can access the printers/scanners and NAS at home.

The 2 rPI’s are used as router (using a Macbook Air USB-to-Ethernet adapter as 2nd ethernet (eth1) port). Basic howto’s are easily found using Google to do this (a good starting point).
