Hi,<br><br><b>My basic need::</b><br><br>I am writing a <b>simple socket programme </b>and as input to programme I want to give the<b> IP address of containers</b>.

Hi Nishant,<br>
<br>
I removed Cc: to containers@ as your troubles are about using the lxc<br>
userspace tool: lxc-users@ is THE place for seeking help.<br>

</div>I still don't understand what you intend to do... All I can say is that<br>
using lxc-execute to partially start a container (that's what you're<br>
doing when you want do lxc-execute /etc/init.d/networking) is a total<br>
nonsense. Sorry.<br>

</div>Your containers don't get their IP addresses in a vacuum... Either the<br>
addresses are statically configured is some distro specific file, either<br>
they are assigned by an external service (DHCP most of the time).<br>
In the first case, you can probably find the address by parsing the<br>
appropriate file from your container's filesystem<br>
(/etc/sysconfig/network-scripts/ifcfg-eth0 for example on redhat). In<br>
the second case, it depends on the DHCP server setup... please see that<br>
with your sysadmin.<br>
<div class="im"><br>

<br>
</div>As told before, nonsense.<br>

<br>
That's what several people on the list are trying to do... If you really<br>
need help, stop asking about how to misuse lxc-execute and give some<br>
hints about your network setup... Do your containers use static<br>
addresses ? Do they rely on a DHCP server ? Are you sysadmin for the<br>
DHCP server ?<br>
<br>
Unless you provide more context, I'm afraid nobody will be able to help<br>
you...<br>
<br>
Cheers.<br>
