dhcp - Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) enables host sys-
tems in a TCP/IP network to be configured automatically for
the network as they boot. DHCP uses a client/server mechan-
ism: servers store configuration information for clients,
and provide that information upon a client's request. The
information can include the client's IP address and informa-
tion about network services available to the client.
This manual page provides a brief summary of the Solaris
Solaris DHCP Client
The Solaris DHCP client is implemented as background daemon,
dhcpagent(1M). This daemon is started automatically during
bootup if there exists at least one dhcp.interface file in
/etc. Only interfaces with a corresponding
/etc/dhcp.interface file are automatically configured during
boot. Network parameters needed for system configuration
during bootup are extracted from the information recieved by
the daemon through the use of the dhcpinfo(1) command. The
daemon's default behavior can be altered by changing the
tunables in the /etc/default/dhcpagent file. The daemon is
controlled by the ifconfig(1M) utility. Check the status of
the daemon using the netstat(1M) and ifconfig(1M) commands.
Solaris DHCP Server
The Solaris DHCP server is implemented as a background dae-
mon, in.dhcpd(1M). This daemon can deliver network confi-
guration information to either BOOTP or DHCP clients. The
Solaris DHCP service can be managed using the dhcpmgr(1M)
GUI or the command line utilities dhcpconfig(1M),
dhtadm(1M), and pntadm(1M).
DHCP Configuration Tables
The Solaris DHCP server stores client configuration informa-
tion in the following two types of tables:
Contain macros and options (also known as symbols),
used to construct a package of configuration informa-
tion to send to each DHCP client. There exists only
one dhcptab for the DHCP service. The dhcptab(4) can
be viewed and modified using the dhtadm(1M) command or
dhcpmgr(1M) graphical utility. See dhcptab(4) for more
information about the syntax of dhcptab records. See
dhcp_inittab(4) for more information about the DHCP
options and symbols.
DHCP network tables
DHCP network tables, which contain mappings of client
IDs to IP addresses and parameters associated with
those addresses. Network tables are named with the IP
address of the network, and can be created, viewed,
and modified using the pntadm command or dhcpmgr
graphical utility. See dhcp_network(4) for more infor-
mation about network tables.
