I must have the ability to change my Mini2440 network parameters from my Qt app. I have a few questions regarding this: 1.) What would be the best way to do that? Change the contents of /etc/network/interfaces? 2.) Does the network have to be enabled in the bootloader settings? If its not enabled in the bootloader, how can I enable it from my Qt app? sudo /etc/init.d/networking start? (Does ptxdist accept sudo as a command)
Nobody got any ideas?
If you always change the settings when your Qt app is started you can take a look into the "ifconfig" source how to do so. If you only want to change it once and the new setting should be persistent you should change the "/etc/network/interfaces" content instead. Currently root filesystems built by PTXdist have no real user management. So, your Qt app runs as root as well and does not need any "sudo" command. If you changed the user of your Qt app: yes, "sudo" is supported and can be used at run-time.
