and enabled Restart=on-abort (fate#315133).
- Update to ISC dhcp-4.2.6 release. See RELNOTES file for the
complete list of changes -- digest of fixes not in dhcp-4.2.5:
- Tidy up receive packet processing.
Thanks to Brad Plank of GTA for reporting the issue and
suggesting a possible patch. [ISC-Bugs #34447]
- Fix the socket handling for DHCPv6 clients to allow multiple
instances of a client on a single machine to work properly.
Previously only one client would receive the packets.
Thanks to Jiri Popelka at Red Hat for the bug report and a
potential patch. [ISC-Bugs #34784]
- Added support for gentle shutdown after signal is received.
[ISC-Bugs #32692] [ISC-Bugs 34945]
- Enhance the DHCPv6 server logging to include the addresses
that are assigned to the clients. This can be enabled by
defining LOG_V6_ADDRESSES in site.h. [ISC-Bugs #26377]
- Fix an operation in the DDNS code to be a bitwise instead
of logical or. [ISC-Bugs #35138]
- Merged patches for dhcp-4.2.6 version to apply without fuzzy,
prepended patch number prefixes to match spec file patch nr,
added patch markup tags / bug numbers to the spec file.
- Applied contrib-lease-path pach to contrib.tar.gz
[- contrib-lease-path.diff]
- Changed to require automake and use its config.sub and guess
files instead of maintaining a patch.
[- config-guess-sub-update.patch]
- Enabled to log DHCPv6 addresses assigned by server to clients
[+ 0016-server-log-DHCPv6-addresses-assigned-to-clients.patch]
- Cleaned up documentation, rpmlint adjustments.

Before you can run dhcpd, you have to configure it via
|
|
- /etc/sysconfig/dhcpd (general settings)
|
|
and
|
|
- /etc/dhcpd.conf (DHCPv4 configuration file)
|
|
- /etc/dhcpd6.conf (DHCPv6 configuration file)
|
|
|
|
See /usr/share/doc/packages/dhcp-server for example configurations.
|
|
|
|
|
|
Option 119 (domain-search) vs. option 15 (domain-name)
|
|
======================================================
|
|
|
|
The domain-name option supports only one, signgle domain (default domain).
|
|
The domain-search option supports a list of domain names. Please do not
|
|
abuse the domain-name option to provide a list -- it may be discarded by
|
|
dhcp clients.
|
|
|
|
|
|
Chroot Jail
|
|
===========
|
|
|
|
Our version of the ISC dhcp server contains a modified "(non-root/chroot)"
|
|
patch by Ari Edelkind. This allows dhcpd to
|
|
|
|
- run as unprivileged user
|
|
- run in a chroot environment (/var/lib/dhcp)
|
|
|
|
which, in this combination, is the safest possible way of running dhcpd.
|
|
|
|
In order to be found by dhcpd in the chroot jail, the configuration file
|
|
will automatically copied to /var/lib/dhcp/etc/ when the server is started.
|
|
Further conf files (include files) can be listed in DHCPD_CONF_INCLUDE_FILES
|
|
or DHCPD6_CONF_INCLUDE_FILES in /etc/sysconfig/dhcpd.
|
|
|
|
The /var/lib/dhcp/dev/log syslog socked is automatically provided in the
|
|
chroot environment as soon as it is initially set up.
|
|
|
|
NOTE:
|
|
In the chroot jail, dhcpd can't resolve hostnames unless it can find
|
|
the following files:
|
|
/etc/localtime
|
|
/etc/host.conf
|
|
/etc/hosts
|
|
/etc/resolv.conf
|
|
/lib/libresolv.so.2
|
|
/lib/libnss_dns.so.2
|
|
/lib/libnss_dns6.so.2
|
|
....
|
|
Thererore, these files (about 100 kB) will automatically copied to the chroot
|
|
jail when the server is started. (You might have to keep these current if
|
|
they are modified dynamically by other programs (e.g./etc/ppp/ip-up) while
|
|
dhcpd is running.) This is not a problem at all when you use IP addresses
|
|
instead of host names in the config file.
|
|
|
|
In case of trouble, you can also disable the chroot feature by setting
|
|
DHCPD_RUN_CHROOTED/DHCPD6_RUN_CHROOTED in /etc/sysconfig/dhcpd to "no".
|
|
|
|
Have a lot of fun!
