Requirement
A DHCP server can provided static or dynamic address.
However, the DHCP server's IP @ must always be static!!
If you want to use a DNS, then you can even setup the DNS server first. See DNS server
Installation
DHCP server
apt-get install isc-dhcp-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.
