NetPacket::UDP is a Perl module to assemble and disassemble UDP (User Datagram Protocol) packets. SYNOPSIS use NetPacket::UDP; $udp_obj = NetPacket::UDP->decode($raw_pkt); $udp_pkt = NetPacket::UDP->encode($ip_obj); $udp_data = NetPacket::UDP::strip($raw_pkt); NetPacket::UDP provides a set of routines for assembling and disassembling packets using UDP (User Datagram Protocol). Methods NetPacket::UDP->decode([RAW PACKET]) Decode the raw packet data given and return an object containing instance data. This method will quite happily decode garbage input. It is the responsibility of the programmer to ensure valid packet data is passed to this method. NetPacket::UDP->encode(param => value) Return a UDP packet encoded with the instance data specified. Needs parts of the ip header contained in $ip_obj, the IP object, in order to calculate the UDP checksum. The length field will also be set automatically. Functions NetPacket::UDP::strip([RAW PACKET]) Return the encapsulated data (or payload) contained in the UDP packet. This data is suitable to be used as input for other NetPacket::* modules. This function is equivalent to creating an object using the decode() constructor and returning the data field of that object. Instance data The instance data for the NetPacket::UDP object consists of the following fields. src_port The source UDP port for the datagram. dest_port The destination UDP port for the datagram. len The length (including length of header) in bytes for this packet. cksum The checksum value for this packet. data The encapsulated data (payload) for this packet..
