Running script when network interface is up

Hi all,

i am trying to run this script when network interface is up on my N9:

Code:

#!/bin/sh

date >> /root/data

The script path is:

Code:

/etc/network/if-up.d/50_connect_home

The file /root/data is an existing empty file.

Upon connecting to my wlan, the file /root/data is still empty, which suggests the script does not run.

Any pointers?

Thanks,
sargas.

Forgive me if I'm wrong, for I don't have a N9 myself, but doesn't Aegis prevent modification of files owned by root, even by root itself?

Try to append the data to a file in your home folder.

I guess not since i can execute the script manually, as root, and the file gets modified.

Trying with /home/user/data, like sugested, has no effect either.
I think there is something more to be done than just putting the script in /etc/network/if-up.d/ but i can't figure it out.

Re: Running script when network interface is up

Quick reply...
Look up file "/etc/network/interfaces". Besides lines "address ...", "netmask ....", "gateway ...", there can also be lines "up ...." and "down ..." - to run scripts when a connection starts and stops.
Best wishes.

Re: Running script when network interface is up

So, what does your check for ifup look like? The condition itself, if you like, not what you do if and when the condition is met.

Re: Running script when network interface is up

Quick reply...
Contents of file "/etc/network/interaces":

Code:

auto usb0

iface usb0 inet static

        address 192.168.2.15

        netmask 255.255.255.0

        gateway 192.168.2.14

        up /usr/lib/sdk-connectivity-tool/usbdhcpd.sh 192.168.2.14

        down /usr/lib/sdk-connectivity-tool/usbdhcpd.sh stop

With appropriate setup on PC, it allows to give Internet from PC to Harmattan device.
Best wishes.

Re: Running script when network interface is up

try to set a execute bit

Code:

sudo chmod +x path_to_script

also you can try to use full path for echo instead of it's binary name
or jsut set up a PATH variable

Code:

#!/bin/sh

PATH=$PATH:/bin

This could be the cause here.

Thanks, but still not working. I have tried to add:

Code:

  

auto wlan0

        iface wlan0 inet dhcp

        up /etc/network/if-up.d/50_connect_home

to /etc/network/interfaces

Also tried just one line at end of file:

Code:

up /etc/network/if-up.d/50_connect_home

The script does not run.

Edit: fixed code tags.

Thanks, but first thing i've tried was to set the script executable.
