What is the difference between install / configure dhcp-server in Ubuntu 13.10 and other versions?
I see a video about configure dhcp-server in Ubuntu 12 but I can't configure it in Ubuntu 13.10.
Install means to copy the files needed to run an application into the right folders, making the necessary changes needed by the application.
Configure means to change the settings of an application that is installed on your system to suit the user/system preferences for it to run properly.
In your case would be to get DHCP server loaded to the system, getting it to the right locations, and then configuring it by setting up the correct network preferences, to suit your needs and particular configuration for it to work properly.
