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, broadcast 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
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
interface
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 previously assigned IP address. The word
interface
is actually replaced with the network interface name like
eth0
to which
dhcpcd
is attached.
SEE ALSO
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.
