DHCP - Dynamic Host Configuration Protocol

Created: 18 December 2013 | Written by Super User | Print | Email | Hits: 102027

Installieren von DHCP Server

apt-get install dhcp3-server

You will be asked a few questions:

On what network interfaces should the DHCP server listen? <-- eth0
Please configure the DHCP server as soon as the installation finishes. <-- Ok
The version 3 DHCP server is now non-authoritative by default <-- Ok

At the end of the installation you will see errors like these:

Generating /etc/default/dhcp3-server...
Starting DHCP server: dhcpd3 failed to start - check syslog for diagnostics.
invoke-rc.d: initscript dhcp3-server, action "start" failed.

That's ok because we did not have the chance yet to configure our DHCP server.
