If you want to install this package, the instructions can be found at . Note that if you only want to use the client, you do not need to run the server and so do not need the startup script and links provided for the server daemon. You only need to run the DHCP server if you're providing this service to a network, and it's likely that you'll know if that's the case; if it isn't, don't run the server! Once you have installed the package, return here for information on how to configure the client (dhclient). To configure dhclient, you need to first install the network service script, /lib/services/dhclient included in the package (as root): dhclient (service script) make install-service-dhclient Next, create the /etc/sysconfig/ifconfig.eth0 configuration file with the following commands as the root user. Adjust as necessary for additional interfaces: /etc/sysconfig/ifconfig.eth0 cat > /etc/sysconfig/ifconfig.eth0 << "EOF" ONBOOT="yes" IFACE="eth0" SERVICE="dhclient" DHCP_START="<add additional start parameters here> eth0" DHCP_STOP="-r <add additional stop parameters here>" # Set PRINTIP="yes" to have the script print # the DHCP assigned IP address PRINTIP="no" # Set PRINTALL="yes" to print the DHCP assigned values for # IP, SM, DG, and 1st NS. This requires PRINTIP="yes". PRINTALL="no" EOF For more information on the appropriate DHCP_START and DHCP_STOP values, examine the man page for dhclient. Finally, you should create the /etc/dhclient.conf file using the following commands as the root user: /etc/dhclient.conf You'll need to add a second interface definition to the file if you have more than one interface. cat > /etc/dhclient.conf << "EOF" # dhclient.conf interface "eth0"{ prepend domain-name-servers 127.0.0.1; request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, host-name; require subnet-mask, domain-name-servers; } # end dhclient.conf EOF
