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.
|
