Packet Builder

Packet Builder is a tool used for constructing your own custom packets and sending them into the network. You could use this feature to check your network's robustness against intruders or attack.

You can use the hexadecimal editor to create a packet or you can use one of the provided templates. Any changes are immediately displayed in the decoder window (in the left pane). This screenshot shows example of an ARP query under construction.

Here are the toolbar buttons and their functions:

	Creates a packet from a template (ARP, UDP, etc.)
	Changes the size of the packet.
	Loads the packet from a file.
	Saves the current packet to a file.
	Calculates the checksum of the packet (for IP, TCP and UDP).
	Sends the packet into the network.
