| dhcpcd - DHCP client daemon |

| |
| Installation |
| ------------ |
| ./configure; make; make install |
| man dhcpcd for command line options |
| man dhcpcd.conf for configuration options |
| man dhcpcd-run-hooks to learn how to hook scripts into dhcpcd events |
| |
| |
| Notes |
| ----- |
| If you're cross compiling you may need set the platform if OS is different |
| from the host. |
| --target=sparc-sun-netbsd5.0 |
| |
| If you're building for an MMU-less system where fork() does not work, you |
| should ./configure --disable-fork. |
| This also puts the --no-background flag on and stops the --background flag |
| from working. |
| |
| You can change the default dirs with these knobs. |
| For example, to satisfy FHS compliance you would do this:- |
| ./configure --libexecdir=/lib/dhcpcd dbdir=/var/lib/dhcpcd |
| |
| We now default to using -std=c99. For 64-bit linux, this always works, but |
| for 32-bit linux it requires either gnu99 or a patch to asm/types.h. |
| Most distros patch linux headers so this should work fine. |
| linux-2.6.24 finally ships with a working 32-bit header. |
| If your linux headers are older, or your distro hasn't patched them you can |
| set CSTD=gnu99 to work around this. |
| |
| Some BSD systems do not allow the manipulation of automatically added subnet |
| routes. You can find discussion here: |
| http://mail-index.netbsd.org/tech-net/2008/12/03/msg000896.html |
| BSD systems where this has been fixed are: |
| NetBSD-5.0 |
| |
| We try and detect how dhcpcd should interact with system services during the |
| configure stage. If we cannot auto-detect how do to this, or it is wrong then |
| you can change this by passing shell commands to --service-exists, |
| --servicecmd and optionally --servicestatus. |
| |
| To prepare dhcpcd for import into a platform source tree (like NetBSD) |
| you can use the make import target to create /tmp/dhcpcd-$version and |
| populate it with all the source files and hooks needed. |
| In this instance, you may wish to disable some configured tests when |
| the binary has to run on older versions which lack support, such as getline. |
| ./configure --without-getline |
| |
| |
| Hooks |
| ----- |
| Not all the hooks in dhcpcd-hooks are installed by default. |
| By default we install 01-test, 10-mtu, 20-resolv.conf, |
| 29-lookup-hostname and 30-hostname. |
| The default dhcpcd.conf disables the lookup-hostname hook by default. |
| The configure program attempts to find hooks for systems you have installed. |
| To add more simply |
| ./configure -with-hook=ntp.conf |
| |
| |
| Compatibility |
| ------------- |
| dhcpcd-5.0 is only fully command line compatible with dhcpcd-4.0 |
| For compatibility with older versions, use dhcpcd-4.0 |
| |
| dhcpcd no longer sends a default ClientID for ethernet interfaces. |
| This is so we can re-use the address the kernel DHCP client found. |
| To retain the old behaviour of sending a default ClientID based on the |
| hardware address for interface, simply add the keyword clientid to dhcpcd.conf. |

| We no longer supply a ChangeLog. |
