Execute a script when a network-interface come up?

Hey

I have tried to figure out, where I should place a file, which should be
executed when a network-interface come up
I have tried /etc/network/if-up.d, but it didn't help

man interfaces:

"There exists for each of the above mentioned options a directory
/etc/network/if-<option>.d/ the scripts in which are run (with
no arguments) using run-parts(8) after the option itself has been
processed.

From context, I'd suggest that <option> can be one of the following
keywords: pre-up, up, post-up, down, pre-down, post-down.


man run-parts:

"If the --lsbsysinit option is not given then the names must consist
entirely of upper and lower case letters, digits, underscores,
and hyphens.

"Files are run in the lexical sort order of their names unless
the --reverse option is given, in which case they are run in the
opposite order.


If you've already worked through these two man pages then you'll need
to give some more information, such as file names, what the program is
trying to do, and how you know "it didn't help"

Over 200+ linux distributions out there.
Always provide distribution, release, and if Mandriva/drake, RCn,
official, cooker, when posting questions.
It could help you get better answers.

Are you sure. Create another script, say a_test, with the following

env > /tmp/a_test.env
exit 0


Then do a
chmod +x a_test

Now bounce the network connection.
On Redhat and Mandriva/drake the command is

service network restart

Now check if a_test ran with
cat /tmp/a_test.env

On Mandriva/drake directory is /etc/sysconfig/network-scripts/ifup.d/

What Linux distribution? On Red-Hat-like systems, you put the script in
/sbin and name it "ifup-local". It gets called from scripts in
/etc/sysconfig/network-scripts:

/sbin/ifup-local ${DEVICE}

I actually have mine in /usr/local/sbin with just a symlink in /sbin.

The filename is net.sh
It's a script, I have programmed myself
The script should try to get an url, but there should be no output, so
the script looks like:
wget --output-file=/dev/null <url to my server> > /dev/null

On my server the page it should visit should take the ip address from
the laptop, so it could be set up to apache like a virtualhost

Does it also work on Kubuntu :s
I haven't found a newsreader on Kubuntu, so I'm using Windows, when I'm
reading newsmails

You are the one to tell us if it works or not.

I believe the script has to have numbers as the first two characters and
be set to executable.

i.e

chmod +x 01myscript
