Hi,

Can any one point me toward some focused reading and/or sample code for changing the IP address on the eth0 device from code 'on the fly'.

I know how to do it using the configuration files that are read on boot/linux startup.  I could have my program adjust those files and then force the user to re-boot.  I am hoping there is a way to have the user edit the IP address through my program and then make it take effect.

Thanks,  Dave S.

You can use system call to change it,

  system("ifconfig eth0 xxx.xxx.xxx.xxx");

The program must have the privilege to run ifconfig command.
