Detailed Description

Sends packets over a raw Socket.

This class can be used to send packets to a destination ip address. It uses raw sockets to do so. On unix tcp and udp packets can be send, on windows, since XP SP3, the use of raw sockets is restricted, only udp packets can be send.

Member Function Documentation

ulong whisper_library::SocketSender::ipToUlong ( string  ip )

private

converts a ip from string to ulong representation

Parameters

ip	the IPv4 as text

Returns

the IPv4 as ulong

std::string whisper_library::SocketSender::packetToString ( vector< bool >  packetData )

private

converts packet data to string

The packet data gets converted from vector<bool> to std::string, so it can be processed easily.

Parameters

packetData

the data to convert

Returns

a text representation of the data

void whisper_library::SocketSender::sendTcp	(	string	source_ip,
		string	destination_ip,
		TcpPacket	packet
	)

sends a tcp packet to destination ip address

The checksum for the packet is calculated based on the given ip addresses and than the packet is send over a raw socket.

Parameters

source_ip	the senders ip address
destination_ip	the receivers ip address
packet	the packet that gets send

void whisper_library::SocketSender::sendUdp	(	string	destination_ip,
		UdpPacket	packet
	)

sends a udp packet to destination ip address

Parameters

destination_ip	the receivers ip address
packet	the packet that gets send
