grafana service doesn’t auto start with the system

When installing grafana and influxDB. I encountered the folowing issue

The service of grafana and influxDB where not starting .

I checked using rcconf that my service where enabled , and they where !

I then tried sysv-rc-conf and my service where correctly configured !

the services had absolutely no issue starting when called manually and started fine !

this line was telling me that the service startup was disabled !

after seaching a bit on the web ,the solution to this issue is using systemctl to enables the services.

InfluxDB insert multiples values at once using curl

If you have to insert multiples values in an influxdb database. You can use curl and insert the values one at the time.

But there is a better way like in this example

Let’s say you want to insert your tree loadaverage values in you influxdb database.

First put them into variables using these 3 lines.

Then using this curl line, insert them all at once in your influxdb database

OrangePI : Install OpenRTSP on a ARM device

One of my project with my OrangePI is to setup the device as a basic IP security camera server ,

the OrangePI zero , will connect to RTSP flux of the IP camera , and dump the stream on to an external disk , where it will be kept for 7 days before getting automaticly deleted
At a latter date i will run a motion detection program on these files and send a mail if motion is detected on a specific part of the frame.

after a little research , i found that a lot of people are using a program called openRTSP to record their RTSP stream to disk

But , after connecting on my OrangePi zero and trying to look for the program i found out that it’s not part of the default installation of armbian stable.

I tried to install the package using apt install openRTSP

I went to google and searched , openRTSP package ,and found out , on the debian website that openRTSP is part of the livemedia-utils package,

I went back to my SSH session and typed apt-get install livemedia-utils

There is no man pages associated with the program , you have to rely on the developer website to understand all the different options . The documentation is available here :  or here if the website is down.
but as usual , in the officials repositories you only get dated version

you might want to compile the source code to have the last version available:

as root

Go to /usr/src: cd /usr/src
Get the live555 liveMedia source code: wget
Unpack it: tar -xzf live555-latest.tar.gz
Go into the  unpacked directory: cd live
Generate the make files: ./genMakefiles linux
Build the code: make
Install the latest version: make install

Bash script to clean movies name

The issue when you download movies online, is that most of the time the file name is going to be complete trash , filled with useless info like the team that made the rip or the website from where the movie was downloaded.
This is very annoying when you sort by name and the website made the idiotic decision to put their name in front of the actual film name.

for example here a typical movie name
[ ] Dont.Think.Twice.2016.FRENCH.WEBRip.XviD-NEWCiNE.avi
the actual useful data that i wish to keep is Dont.Think.Twice.2016.avi

for this purpose i’ve developped a small bash script that will list all the files in a chosen directory then , if necessary , will rename the file.

this is not a very efficient script
but it’s fulfill it’s purpose and very rarely encounter a filename that he is unable to clean.
