+dhcpd - Dynamic Host Configuration Protocol Client
+.SH SYNOPSIS
+.B dhclient

+]

+[
+.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.

+so as to use the same networking framework that the Internet Software

+ 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

+ This client was substantially modified and enhanced by
+ Elliot Poger for use on Linux while he was working on the
+ MosquitoNet project at Stanford.
+
+ The current version owes much to Elliot's Linux enhance-
+ ments, 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.

+.SH DESCRIPTION
+The Internet Software Consortium DHCP Relay Agent, dhcrelay, provides a
+means for relaying DHCP and BOOTP requests from a subnet to which
+no DHCP server is directly to one or more DHCP servers on other
+subnets.
+.SH OPERATION
+.PP
+The DHCP Relay Agent listens for DHCP requests on all interfaces
+attached to a host, or only on those interfaces specified on the
+command line with the
+.I -i
+flag. When a query is received, it forwards it to the list of DHCP
+servers specified on the command line. When a reply is received, it
+is broadcast or unicast on the network from whence the original
+request came.
+.PP
+It is possible to specify a set of interfaces on which dhcrelay will
+listen, so that if dhcrelay is connected through one interface to a
+network on which there is no DHCP server, but is connected on another
+interface to a network on which there is a DHCP server, it will not
+relay DHCP and BOOTP requests from the network on which the server
+exists to that server. This is an imperfect solution.
+.SH COMMAND LINE
+.PP
+The names of the network interfaces that dhcrelay should attempt to
+configure may be specified on the command line using the
+.I -i
+option. If no interface names
+are specified on the command line dhcrelay will identify all network
+interfaces, elimininating non-broadcast interfaces if possible, and
+attempt to configure each interface.
+.PP
+If dhcrelay should listen and transmit on a port other than the
+standard (port 67), the
+.B -p
+flag may used. It should be followed by the udp port number that
+dhcrelay 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 dhcrelay to always run as a foreground process, the
+.B -d
+flag should be specified. This is useful when running dhcrelay under
+a debugger, or when running it out of inittab on System V systems.
+.PP
+The name of at least one DHCP server to which DHCP and BOOTP requests
+should be relayed must be specified on the command line.
