NAME
       dhcpcd - DHCP client daemon

SYNOPSIS
       dhcpcd   [-c filename]   [-d]   [-i classIdentifier]  [-k]
            [-l leasetime] [-r] [interface]

DESCRIPTION
       dhcpcd is an implementation of the DHCP  client  specified
       in  RFC2131  (when -r option is not specified) and RFC1541
       (when -r option is specified).

       It gets the host information (IP address, netmask,  broad-
       cast  address, etc.) from a DHCP server and configures the
       network interface of the machine on which it  is  running.
       It also tries to renew the lease time according to RFC2131
       or RFC1541 (obsolete).

OPTIONS
       -c filename
              Specifies the command file which  is  invoked  when
              dhcpcd successfully gets an IP address.

       -d     Forces dhcpcd to run in the foreground.

       -i classIdentifier
              Specifies the class identifier string.  dhcpcd uses
              the default class identifier string  (system  name,
              sytem release, and machine type) if it is not spec-
              ified.

       -k     Sends a SIGTERM signal to the dhcpcd  process  that
              is currently running.

       -l leasetime
              Specifies  (in  seconds) the recommended lease time
              to the server. (Note that the server  can  override
              this  value  if it sees fit). This value is used in
              the DHCPDISCOVER message.

       -r     Makes dhcpcd RFC1541 (obsolete)  compliant.  dhcpcd
              is  RFC2131  compliant unless this option is speci-
              fied.

       interface
              Specifies the network interface name  (eth0,  eth1,
              etc.).   dhcpcd  uses  the  network  interface eth0
              unless an explicit name is specified.

FILES
       /etc/dhcpc               directory used for storing  files
                                created by dhcpcd
       /etc/dhcpc/hostinfo-interface
                                file  in  which  dhcpcd saves the
                                host information. The word inter-
                                face  is  actually  replaced with
                                the network interface  name  like
                                eth0 to which dhcpcd is attached.
       /etc/dhcp/resolv.conf    file created by dhcpcd  when  the
                                client  receives  DNS  and domain
                                name options
       /var/run/dhcpcd-pid      file containing the process id of
                                dhcpcd
       /var/run/dhcpcd-cache.interface
                                cache  file containing the previ-
                                ously assigned  IP  address.  The
                                word    interface   is   actually
                                replaced with the network  inter-
                                face  name  like  eth0  to  which
                                dhcpcd is attached.

BUGS
       dhcpcd  uses  time(3)  to  calculate  the lease expiration
       time.  If the system time is changed while the  client  is
       running, the lease expiration time may not be predictable.

       dhcpcd does not support the DHCPINFORM message.

       dhcpcd cannot handle DHCP options (e.g. domain name) which
       have  more  than 255 characters. All the DHCP options have
       to be less than or equal to 255.
