-.SH NAME
-dhcpd - Dynamic Host Configuration Protocol Client
-.SH SYNOPSIS
-.B dhclient
-[
-.B -p
-.I port
-]
-[
-.B -d
-]
-[
-.I if0
-[
-.I ...ifN
-]
-]
-.SH DESCRIPTION
-The Internet Software Consortium DHCP Client, dhclient, provides a
-means for configuring one or more network interfaces using the Dynamic
-Host Configuration Protocol, BOOTP protocol, or if these protocols
-fail, by statically assigning an address.
-.SH OPERATION
-.PP
-The DHCP protocol allows a host to contact a central server which
-maintains a list of IP addresses which may be assigned on one or more
-subnets.   A DHCP client may request an address from this pool, and
-then use it on a temporary basis for communication on network.   The
-DHCP protocol also provides a mechanism whereby a client can learn
-important details about the network to which it is attached, such as
-the location of a default router, the location of a name server, and
-so on.
-.PP
-On startup, dhclient reads the
-.IR dhclient.conf
-for configuration instructions.   It then gets a list of all the
-network interfaces that are configured in the current system.   For
-each interface, it attempts to configure the interface using the DHCP
-protocol.
-.PP
-In order to keep track of leases across system reboots and server
-restarts, dhclient keeps a list of leases it has been assigned in the
-dhclient.leases(5) file.   On startup, after reading the dhclient.conf
-file, dhclient reads the dhclient.leases file to refresh its memory
-about what leases it has been assigned.
-.PP
-When a new lease is acquired, it is appended to the end of the
-dhclient.leases file.   In order to prevent the file from becoming
-arbitrarily large, from time to time dhclient creates a new
-dhclient.leases file from its in-core lease database.  The old version
-of the dhclient.leases file is retained under the name
-.IR dhcpd.leases~
-until the next time dhclient rewrites the database.
-.PP
-Old leases are kept around in case the DHCP server is unavailable when
-dhclient is first invoked (generally during the initial system boot
-process).   In that event, old leases from the dhclient.leases file
-which have not yet expired are tested, and if they are determined to
-be valid, they are used until either they expire or the DHCP server
-becomes available.
-.PP
-A mobile host which may sometimes need to access a network on which no
-DHCP server exists may be preloaded with a lease for a fixed
-address on that network.   When all attempts to contact a DHCP server
-have failed, dhclient will try to validate the static lease, and if it
-succeeds, will use that lease until it is restarted.
-.PP
-A mobile host may also travel to some networks on which DHCP is not
-available but BOOTP is.   In that case, it may be advantageous to
-arrange with the network administrator for an entry on the BOOTP
-database, so that the host can boot quickly on that network rather
-than cycling through the list of old leases.
-.SH COMMAND LINE
-.PP
-The names of the network interfaces that dhclient should attempt to
-configure may be specified on the command line.  If no interface names
-are specified on the command line dhclient will identify all network
-interfaces, elimininating non-broadcast interfaces if possible, and
-attempt to configure each interface.
-.PP
-If dhclient should listen and transmit on a port other than the
-standard (port 68), the
-.B -p
-flag may used.  It should be followed by the udp port number that
-dhclient should use.  This is mostly useful for debugging purposes.
-.PP
-Dhclient will normally run in the foreground until it has configured
-an interface, and then will revert to running in the background.
-To run force dhclient to always run as a foreground process, the
-.B -d
-flag should be specified.  This is useful when running dhclient under
-a debugger, or when running it out of inittab on System V systems.
-.PP
-.SH CONFIGURATION
-The syntax of the dhclient.conf(8) file is discussed seperately.
-.SH FILES
-.B ETCDIR/dhclient.conf, DBDIR/dhclient.leases, RUNDIR/dhclient.pid,
-.B DBDIR/dhclient.leases~.
-.SH SEE ALSO
-dhcpd(8), dhcrelay(8), dhclient.conf(5), dhclient.leases(5)

-.PP
-This client was substantially modified and enhanced by Elliot Poger
-for use on Linux while he was working on the MosquitoNet project at
-Stanford.
-.PP
-The current version owes much to Elliot's Linux enhancements, but
-was substantially reorganized and partially rewritten by Ted Lemon
-so as to use the same networking framework that the Internet Software
-Consortium DHCP server uses.   Much system-specific configuration code
-was moved into a shell script so that as support for more operating
-systems is added, it will not be necessary to port and maintain
-system-specific configuration code to these operating systems - instead,
-the shell script can invoke the native tools to accomplish the same
-purpose.
