-				 SCO
-
-ISC DHCP will now work correctly on newer versions of SCO out of the
-box (tested on OpenServer 5.05b, assumed to work on UnixWare 7).
-
-Older versions of SCO have the same problem as Linux (described earlier).
-The thing is, SCO *really* doesn't want to let you add a host route to
-the all-ones broadcast address.
-
-You can try the following:
-
-  ifconfig net0 xxx.xxx.xxx.xxx netmask 0xNNNNNNNN broadcast 255.255.255.255
-
-If this doesn't work, you can also try the following strange hack:
-
-  ifconfig net0 alias 10.1.1.1 netmask 8.0.0.0
-
-Apparently this works because of an interaction between SCO's support
-for network classes and the weird netmask.  The 10.* network is just a
-dummy that can generally be assumed to be safe.   Don't ask why this
-works.   Just try it.   If it works for you, great.
-
-				HP-UX
-
-HP-UX has the same problem with the all-ones broadcast address that
-SCO and Linux have.   One user reported that adding the following to
-/etc/rc.config.d/netconf helped (you may have to modify this to suit
-your local configuration):
-
-INTERFACE_NAME[0]=lan0
-IP_ADDRESS[0]=1.1.1.1
-SUBNET_MASK[0]=255.255.255.0
-BROADCAST_ADDRESS[0]="255.255.255.255"
-LANCONFIG_ARGS[0]="ether"
-DHCP_ENABLE[0]=0
-
-				ULTRIX
-
-Now that we have Ultrix packet filter support, the DHCP Distribution
-on Ultrix should be pretty trouble-free.  However, one thing you do
-need to be aware of is that it now requires that the pfilt device be
-configured into your kernel and present in /dev.  If you type ``man
-packetfilter'', you will get some information on how to configure your
-kernel for the packet filter (if it isn't already) and how to make an
-entry for it in /dev.
-
-			       FreeBSD
-
-Versions of FreeBSD prior to 2.2 have a bug in BPF support in that the
-ethernet driver swaps the ethertype field in the ethernet header
-downstream from BPF, which corrupts the output packet.   If you are
-running a version of FreeBSD prior to 2.2, and you find that dhcpd
-can't communicate with its clients, you should #define BROKEN_FREEBSD_BPF 
-in site.h and recompile.
-
-Modern versions of FreeBSD include the ISC DHCP 3.0 client as part of
-the base system, and the full distribution (for the DHCP server and
-relay agent) is available from the Ports Collection in
-/usr/ports/net/isc-dhcp3, or as a package on FreeBSD installation
-CDROMs.
-
-			      NeXTSTEP
-
-The NeXTSTEP support uses the NeXTSTEP Berkeley Packet Filter
-extension, which is not included in the base NextStep system.  You
-must install this extension in order to get dhcpd or dhclient to work.
-
-			       SOLARIS
-
-There are two known issues seen when compiling using the Sun compiler.
-
-The first is that older Sun compilers generate an error on some of
-our uses of the flexible array option.  Newer versions only generate
-a warning, which can be safely ignored.  If you run into this error
-("type of struct member "buf" can not be derived from structure with
-flexible array member"), upgrade your tools to  Oracle Solaris Studio 
-(previously Sun Studio) 12 or something newer.
-
-The second is the interaction between the configure script and the
-makefiles for the Bind libraries.  Currently we don't pass all
-environment variables between the DHCP configure and the Bind configure.
-
-If you attempt to specify the compiler you wish to use like this:
-
-	CC=/opt/SUNWspro/bin/cc ./configure
-
-"make" may not build the Bind libraries with that compiler.
-
-In order to use the same compiler for Bind and DHCP we suggest the
-following commands:
-
-	CC=/opt/SUNWspro/bin/cc ./configure
-	CC=/opt/SUNWspro/bin/cc make
-
-				Solaris 11
-
-We have integrated a patch from Oracle to use sockets instead of
-DLPI on Solaris 11.  This functionality was written for use with
-Solaris Studio 12.2 and requires the system/header package.
-
-By default this code is disabled in order to minimize disruptions
-for current users.  In order to enable this code you will need to
-enable both USE_SOCKETS and USE_V4_PKTINFO as part of the
-configuration step.  The command line would be something like:
-
-	  ./configure --enable-use-sockets --enable-ipv4-pktinfo
-
-				Solaris 11 and ATF
-
-We have reports that ATF 0.15 and 0.16 do not build on Solaris 11.  The
-following changes to the ATF source code appear to fix this issue:

-One problem which has been observed and is not fixed in this
-patchlevel has to do with using DLPI on Solaris machines.  The symptom
-of this problem is that the DHCP server never receives any requests.
-This has been observed with Solaris 2.6 and Solaris 7 on Intel x86
-systems, although it may occur with other systems as well.  If you
-encounter this symptom, and you are running the DHCP server on a
-machine with a single broadcast network interface, you may wish to
-edit the includes/site.h file and uncomment the #define USE_SOCKETS
-line.  Then type ``make clean; make''.  As an alternative workaround,
-it has been reported that running 'snoop' will cause the dhcp server
-to start receiving packets.  So the practice reported to us is to run
-snoop at dhcpd startup time, with arguments to cause it to receive one
-packet and exit.
-
-	snoop -c 1 udp port 67 > /dev/null &
-
-The DHCP client on Solaris will only work with DLPI.  If you run it
-and it just keeps saying it's sending DHCPREQUEST packets, but never
-gets a response, you may be having DLPI trouble as described above.
-If so, we have no solution to offer at this time, aside from the above
-workaround which should also work here.  Also, because Solaris requires
-you to "plumb" an interface before it can be detected by the DHCP client,
-you must either specify the name(s) of the interface(s) you want to
-configure on the command line, or must plumb the interfaces prior to
-invoking the DHCP client.  This can be done with ``ifconfig iface plumb'',
-where iface is the name of the interface (e.g., ``ifconfig hme0 plumb'').
-
-It should be noted that Solaris versions from 2.6 onward include a
-DHCP client that you can run with ``/sbin/ifconfig iface dhcp start''
-rather than using the ISC DHCP client, including DHCPv6.  Consequently,
-we don't believe there is a need for the client to run on Solaris, and
-have not engineered the needed DHCPv6 modifications for the dhclient-script.
-If you feel this is in error, or have a need, please contact us.
-
-				AIX
-
-The AIX support uses the BSD socket API, which cannot differentiate on
-which network interface a broadcast packet was received; thus the DHCP
-server and relay will work only on a single interface.  (They do work
-on multi-interface machines if configured to listen on only one of the
-interfaces.)
-
-We have reports of Windows XP clients having difficulty retrieving
-addresses from a server running on an AIX machine.  This issue
-was traced to the client requiring messages be sent to the all ones
-broadcast address (255.255.255.255) while the AIX server was sending 
-to 192.168.0.255.
-
-You may be able to solve this by including a relay between the client
-and server with the relay configured to use a broadcast of all-ones.
-
-A second option that worked for AIX 5.1 but doesn't seem to work for
-AIX 5.3 was to:
-	create a host file entry for all-ones (255.255.255.255)
-and then add a route:
-	route add -host all-ones -interface <local-ip-address>
-
-The ISC DHCP distribution does not include a dhclient-script for AIX--
-AIX comes with a DHCP client.  Contribution of a working dhclient-script
-for AIX would be welcome.
-
-
-			       MacOS X
-
-The MacOS X system uses a TCP/IP stack derived from FreeBSD with a
-user-friendly interface named the System Configuration Framework.
-As it includes a builtin DHCPv4 client (you are better just using that),
-this text is only about the DHCPv6 client (``dhclient -6 ...'').  The DNS
-configuration (domain search list and name servers' addresses) is managed
-by a System Configuration agent, not by /etc/resolv.conf (which is a link
-to /var/run/resolv.conf, which itself only reflects the internal state;
-the System Configuration framework's Dynamic Store).
-
-This means that modifying resolv.conf directly doesn't have the
-intended effect, instead the macos script sample creates its own
-resolv.conf.dhclient6 in /var/run, and inserts the contents of this
-file into the Dynamic Store.
-
-When updating the address configuration the System Configuration
-framework expects the prefix and a default router along with the
-configured address. As this extra information is not available via
-the DHCPv6 protocol the System Configuration framework isn't usable
-for address configuration, instead ifconfig is used directly.
-
-Note the Dynamic Store (from which /var/run/resolv.conf is built) is
-recomputed from scratch when the current location/set is changed.
-Running the dhclient-script reinstalls the resolv.conf.dhclient6
-configuration.
