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. - - On startup, dhclient reads the _d_h_c_l_i_e_n_t_._c_o_n_f for configu- - ration instructions. It then gets a list of all the net- - work interfaces that are configured in the current system. - For each interface, it attempts to configure the interface - using the DHCP protocol. - - 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. - - 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 - _d_h_c_p_d_._l_e_a_s_e_s_~ until the next time dhclient rewrites the - database. - - Old leases are kept around in case the DHCP server is - unavailable when dhclient is first invoked (generally dur- - ing 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. - - - - - 1 - - - - - -dhclient(8) dhclient(8) - - - 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. - - 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. - -CCOOMMMMAANNDD LLIINNEE - 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, elimininat- - ing non-broadcast interfaces if possible, and attempt to - configure each interface. - - If dhclient should listen and transmit on a port other - than the standard (port 68), the --pp flag may used. It - should be followed by the udp port number that dhclient - should use. This is mostly useful for debugging purposes. - - 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 --dd flag should be specified. - This is useful when running dhclient under a debugger, or - when running it out of inittab on System V systems. - - -CCOONNFFIIGGUURRAATTIIOONN - The syntax of the dhclient.conf(8) file is discussed - seperately. - -FFIILLEESS - //eettcc//ddhhcclliieenntt..ccoonnff,, //vvaarr//ddbb//ddhhcclliieenntt..lleeaasseess,, - //vvaarr//rruunn//ddhhcclliieenntt..ppiidd,, //vvaarr//ddbb//ddhhcclliieenntt..lleeaasseess~~.. - -SSEEEE AALLSSOO - dhcpd(8), dhcrelay(8), dhclient.conf(5), - dhclient.leases(5) - -AAUUTTHHOORR - ddhhcclliieenntt((88)) has been written for the Internet Software - Consortium by Ted Lemon in cooperation - with Vixie Enterprises.
