%general-entities; ]> $LastChangedBy$ $Date$ dhcpcd dhcpcd is an implementation of the DHCP client specified in RFC2131. A DHCP client is useful for connecting your computer to a network which uses DHCP to assign network addresses. dhcpcd strives to be a fully featured, yet very lightweight DHCP client. &lfs76_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &dhcpcd-md5sum; Download size: &dhcpcd-size; Estimated disk space required: &dhcpcd-buildsize; Estimated build time: &dhcpcd-time; User Notes: Install dhcpcd by running the following commands: ./configure --libexecdir=/lib/dhcpcd \ --dbdir=/var/tmp && make This package does not come with a test suite. Now, as the root user: make install --libexecdir=/lib/dhcpcd: The default /libexec is not FHS-compliant. Since this directory may need to be available early in the boot, /usr/libexec cannot be used either. --dbdir=/var/tmp: The default /var/lib is not FHS-compliant --with-hook=...: You can optionally install more hooks, for example to install some configuration files such as ntp.conf. The set of hooks is in the dhcpcd-hooks directory in the build tree. /etc/dhcpcd.conf /etc/dhcpcd/dhcpcd.conf To configure dhcpcd, you need to first install the network service script, /lib/services/dhcpcd included in the package (as user root): dhcpcd (service script) make install-service-dhcpcd Whenever dhcpcd configures or shuts down a network interface, it executes hook scripts. For more details about those scripts, see the dhcpcd-run-hooks and dhcpcd man pages. Finally, as the root user create the /etc/sysconfig/ifconfig.eth0 configuration file using the following commands. Adjust appropriately for additional interfaces: /etc/sysconfig/ifconfig.eth0 (dhcpcd) cat > /etc/sysconfig/ifconfig.eth0 << "EOF" ONBOOT="yes" IFACE="eth0" SERVICE="dhcpcd" DHCP_START="-b -q <insert appropriate start options here>" DHCP_STOP="-k <insert additional stop options here>" EOF For more information on the appropriate DHCP_START and DHCP_STOP values, examine the man page for dhcpcd. The default behavior of dhcpcd sets the hostname and mtu settings. It also overwrites /etc/resolv.conf and /etc/ntp.conf. These modifications to system files and settings on system configuration files are done by hooks which are stored in /lib/dhcpcd/dhcpcd-hooks. Setup dhcpcd by removing or adding hooks from/to that directory. The execution of hooks can be disabled by using the --nohook (-C) command line option or by the nohook option in the /etc/dhcpcd.conf file. Review the dhcpcd man page for switches to add to the DHCP_START value. /etc/resolv.conf Although not usual, it is possible that you need to configure dhcpcd to use a fixed ip. Here, we give an example. As the root user create the /etc/sysconfig/ifconfig.eth0 configuration file using the following commands. Adjust appropriately for additional interfaces and for the actual ip and router you need: /etc/sysconfig/ifconfig.eth0 (dhcpcd) cat > /etc/sysconfig/ifconfig.eth0 << "EOF" ONBOOT="yes" IFACE="eth0" SERVICE="dhcpcd" DHCP_START="-b -q -S ip_address=192.168.0.10/24 -S routers=192.168.0.1" DHCP_STOP="-k" EOF You can either use DNS servers in /etc/resolv.conf from another system, your preferred servers, or just the example /etc/resolv.conf.head file below as is: cat > /etc/resolv.conf.head << "EOF" # OpenDNS servers nameserver 208.67.222.222 nameserver 208.67.220.220 EOF Installed Program Installed Library Installed Directory dhcpcd /lib/dhcpcd/dev/udev.so /lib/dhcpcd Short Descriptions dhcpcd is an implementation of the DHCP client specified in RFC2131. dhcpcd udev.so add udev support for interface arrival and departure; this is because udev likes to rename the interface, which it can't do if dhcpcd grabs it first. udev.so
