Net::DHCP::Packet - Object methods to create a DHCP packet.
use Net::DHCP::Packet;
use strict;
my $p = new Net::DHCP::Packet('Chaddr' => '0??BCDEF',
'Xid' => hex(0x9F0FD),
'Ciaddr' => '0.0.0.0',
'Siaddr' => '0.0.0.0', 'Hops' => 0);
Represents a DHCP packet as specified in RFC 1533, RFC 2132.
Sets the opcode in the BOOTP type.
Without argument, returns the BOOTP type.
Argument is either:
Net::DHCP::Packet::BOOTREQUEST() { pack('C',0x1) }
Net::DHCP::Packet::BOOTREPLY() { pack('C',0x2) }
Ex. '1' = 10mb ethernet
For most NIC's, the MAC address has 6 bytes.
This field is incremented by each encountered DHCP relay agent.
4 byte transaction id.
2 bytes for elapsed boot time.
2 bytes.
0x0000 = No broadcasts.
0x1000 = Broadcasts.
IP address is an ascci string like '10.24.50.3'.
Optional 64 bytes null terminated string with server host name.
Optional
Argument is reference to a Net::DHCP::Options object.
Without argument, returns the Options object.
The hash %ARGS can contain any of these keys:
Op, Htype, Hlen, Hops, Xid, Secs, Flags, Ciaddr, Yiaddr, Siaddr,
Giaddr, Chaddr, Sname, File
DHCP discover packet
DHCP request packet
DHCP decline packet
DHCP release packet
DHCP inform packet
Converts a Net::DHCP::Packet to a string, ready to put on the network.
The inverse of serialize. Converts a string, presumably a
received UDP packet, into a Net::DHCP::Packet.
Returns a textual representation of the packet, for debugging.

I only ran some simple tests on Windows 2000 with a W2K DHCP server and a USR DHCP server. Not yet tested on Unix platform.
This is free software. It can be distributed and/or modified under the same terms as Perl itself.
