Another package being selected instead of what I am trying

Question

I am trying to install dhcp3-server,but it is instead selecting isc-dhcp-server and its not working as per my expectations. Please help.

 Reading package lists... Done
 Building dependency tree       
 Reading state information... Done
 Note, selecting 'isc-dhcp-server' instead of 'dhcp3-server'

I am following How To Set Up A DHCP Server For Your LAN on the HowtoForge site.

There is nothing like dhcp3 in /etc/init.d

Answer 1

isc-dhcp-server is the new name for the dhcp3-server package, so this is behaving as expected. Debian sarge is fairly old, so you can expect that tutorial to be outdated.

Answer 2

The isc-dhcp-server is marked as Provides: dhcp3-server. The Provides relationship indicates that the isc-dhcp-server offers the same functionality as the dhcp3-server and can be installed in its place. The isc-dhcp-server package is essentially a new version of dhcp3-server under a different name.

The name of the service script reflects the name of the package: it's /etc/init.d/isc-dhcp-server.
