Hi

I am using KDE4 on a PC-104 board that runs a instrument.  One of the
screens allows them to set the IP address.  My thinking was that when they
hit the 'Apply' button I would use the KDESu class to run a command.  But it
always fails. I think it fails because I am using Kubuntu which uses sudo
instead of su.

Here is what I have:

    if (enableDHCP) {
      KDESu::SuProcess suProcess("david","/sbin/dhclient eth0");
      status = suProcess.exec("mypassowrd");
      kWarning() << "Status of set network = " << status;    // falis
      kWarning() << "Check password" <<
suProcess.checkInstall("mypassword"); // fails
}

Does anyone have a suggestion as to how I can get it to work.


I tried chmoding dcclient to 777 but it fails latteer on when it tries to
write files. I could of course follow the whole route and change everything
to 777, but ws hoping to use KDESu as it is more secure, especially since
the instrument is on a network.

Does anyone know of a way to enable root on Kubuntu ?

Thaks in advance for any help
David
