DotschUX-DHCPServer

The DHCP server for non diskless server systems is thought, if you would like to have a DHCP server to assign IP addresses automatically and if you not have already a other DHCP server in the network.

The Dotsch/UX diskless server has already included a configured DHCP server, which assigns the IPs to the diskless clients. So it‘s not possible to setup a diskless server and a standalone DHCP server with the same host or the same network.

• Firstly you must edit the DHCP server configuration by hand and adjust your settings there. Open a terminal
window, at the console, or connect remotely to the diskless server system via ssh.
Edit the config file with your favourite editor. For example „sudo gedit /etc/opt/dotsch_ux/dhcp.conf“ for a
graphical editor, or „sudo nano /etc/opt/dotsch_ux/dhcp.conf“ or „sudo vi /etc/opt/dotsch_ux/dhcp.conf“ for a
text based editor.

• A example of the configuration file, without any changes :

#1. Main config parameters

#

###########################################################################

#SUBNET is the subnet of the clients which should be serverd by the DHCP server

#For example : SUBNET=192.168.1.0

SUBNET=

#NETMASK is the netmask of the subnet which should be served by the DHCP server

#For example : SUBNET=255.255.255.0

#

NETMASK=

#BROADCAST is the broadcast address of the DHCP subnet

#For example BROADCAST=192.168.1.255

#

BROADCAST=

#DOMAIN is the domainname of the DHCP clients

#For example DOMAINNAME=dotsch.de

#

DOMAINNAME=

#IP address of the DNS Server

#Hint : if you have a DSL/Internet router, very often the router acts as DNS

#server

#For example : DNS_SERVER=192.168.1.2

#

DNS_SERVER=

#IP addresses of the default gateway.

#Hint : Mostly your DSL/Internet router

#If you have no gateway and would like to use and http proxy on the diskless

#server, add the IP address of the diskless server (DISKLESS_SERVER)

#For example : DEFAULT_GW=192.168.1.1

#

DEFAULT_GW=

###########################################################################

#

#2. DHCP Configuration

#

###########################################################################

#DHCP Server is on the same host per default. 

#The range from which the DHCP server should assign IP's to the clients

#For example a IP range from 192.168.1.100 to 200 which would be assigned to 

# the diskless clients : 

#          DHCP_RANGE_START="192.168.1.100"

#        DHCP_RANGE_END="192.168.1.200"

#

DHCP_RANGE_START=""

DHCP_RANGE_END=""

• Adjust the parameters SUBNET, NETMASK, BROADCAST, DOMAINNAME, DNS_SERVER, DEFAULT_GW,
DHCP_RANGE_START and DHCP_END for the settings of your network.

Each field must me have a parameter to generate a running DHCP config !

• Start the DHCP server configuration with „sudo /opt/dotsch_ux/bin/configure_dhcp.sh“ or via „Applications“ /
„Dotsch/UX Tools“ / „Configure DHCP Server“ from the graphical desktop
