bootpd(1M) bootpd(1M)
sm=subnet-mask
This tag specifies the client’s subnet mask. subnet-mask is specified as a single IP address.
sr=destination_ip_address gateway_ip_address ...
This tag specifies a list of static routes that the client should put in its routing cache. Each
route consists of a pair of IP addresses. The first address is the destination address, and the
second is the router. Use the gw= option to specify the default route (0.0.0.0) as it is not a
legal destination address.
ss=ip_address
This tag specifies the IP address of a swap server.
Tnnn=generic-data
This is a generic tag where nnn is an RFC1533 option field tag number. Use this option to
configure RFC1533 options not currently supported with
bootpd tag names. This option
allows one to immediately take advantage of future extensions to RFC1533. The generic-data
data can be represented as either a stream of hexadecimal numbers or as a quoted string of
ASCII characters. The length of the generic data is automatically determined and inserted
into the proper fields of the RFC1541-style boot reply.
to=offset
This tag specifies the client’s time zone offset in seconds from UTC. The time offset can be
either a signed decimal integer or the keyword
auto which uses the server’s time zone offset.
Specifying the to symbol as a boolean has the same effect as specifying auto as its value.
ts=ip_address_list
This tag specifies the IP addresses of RFC868 Time Protocol servers.
yd=NIS-domain-name
Specifies the name of the client’s NIS domain.
ys=ip_address_list
Specifies the IP address(es) of NIS servers available to the client. Servers should be listed in
order of preference.
vm=magic-cookie
This tag specifies the RFC1048 vendor information magic cookie. magic-cookie can be one of
the following keywords: auto (indicating that vendor information is determined by the
client’s request), rfc1048 (which always forces an RFC1048-style reply), or
cmu (which
always forces a CMU-style reply).
Vnnn=generic-data
This is a generic tag for vendor specific information where nnn is a vendor defined option field
tag number. The generic-data data can be represented as either a stream of hexadecimal
numbers or as a quoted string of ASCII characters. The length of the generic data is automati-
cally determined and inserted into the vendor specific field of the RFC1541-style boot reply.
xd=ip_address_list
This tag specifies the IP addresses of systems that are running the X Window System Display
Manager and are available to the client. Addresses should be listed in order of preference.
xf=ip_address_list
This tag specifies the IP addresses of X window System font servers available to the client.
Servers should be listed in order of preference.
Dhcpdeny Configuration
The configuration file
/etc/dhcpdeny contains the list of hardware addresses, one address per line, for
clients that will not be served by our server. If we know about some bad clients in the network and we
don’t want to serve them, add the hardware address of those clients in this file. This file, like other
configuration files, takes # character as the starting of a comment.
Dhcptab Configuration
The configuration file
/etc/dhcptab defines groups of IP addresses that to be leased out to clients. It
also specifies certain general behaviors of the server, such as whether or not to give addresses from these
groups to bootp clients or only to DHCP clients.
The configuration file has a format similar to the
/etc/bootptab configuration file, with a keyword fol-
lowed by one or more tag symbols. These tag symbols are separated by colons (:). The general format is:
