/etc/init.d/networking

[aaqib752]

Hey fellows,

When I changed my Raspberry pi's IP to static, I need to restart the networking to make it applicable. But sometime it shows me the following error.

I do install the raspbian again to get rid of this error, but there would be some proper way to get rid of this....
I need help.

Regards,

What happens if you try it using the /etc/init.d script?

sudo /etc/init.d/networking stop
sudo /etc/init.d/networking start
sudo /etc/init.d/networking status

[aaqib752]

sudo /etc/init.d/networking stop
sudo /etc/init.d/networking start
sudo /etc/init.d/networking status

Same error...!

Run it with
sudo bash -x /etc/init.d/networking status and you should get lots of stuff on the screen

On my working Jessie system I get

There's something drastically wrong with your root filesystem. Have you rebooted recently? Is the root fs on a USB device (/dev/sda or suchlike)?

[aaqib752]

I didn't see anything like that as I am using SSH via my PC. Maybe that thing happened but this is not for the first time. Can you suggest me solution whateher it is (/dev/sda or suchlike)???
I am don't understand what this error really means and hot to get rid of.

[aaqib752]

Can you tell me the cause of this problem? I will be carefull for next time...

Thanks and Regards

It is usually a cause of not shutting down properly (pulling the plug) or fiddling with settings and accidentally deleting it. You probably have to start afresh.

As far I remember most of the time I properly shut it down from CLI. What do you mean by fiddling with settings?? I am practicing MQTT and VoIP on it so I need to install some softwares and run some codes......
Sometimes some commands don't work and after some break same commands works properly. I am confused.

[DougieLawson]

There's two ways to corrupt SDCards
1. Pull the power while the system is writing.
2. Run the system with a power supply (or USB-A to microUSB cable) that isn't capable of delivering a steady 5V0 @ 700mA (or better)

#2 can also be a symptom of running too many high current USB devices without having a stronger power supply to support them.

Using command "bash -x /etc/init.d/networking status" I got this......
It is quite different from yours.

[DougieLawson]

In that case your Jessie upgrade has failed to install the latest /etc/init.d/networking script.

Am I supposed to upgrade it??
That will work or I have to install the new OS....

[DougieLawson]

I'd build a new Jessie card and lift the /etc/init.d files from there and drop them on your old card.

Making backup of "networking" file will also work or it is essential to copy the whole directory (init.d)...
I am using 2-3 raspberry so I can manage that.

There is also an issue that when I connect these together for socket communication it shows some other Ip address e.g.,(Connected to 192.168.2.53) where as Ip of my connected PI is (192.168.2.208)....
Sometime this clash may occur. For ifconfig it shows "208" and I can also SSH @ "53" using "PiFinder".
Thats very strange.
