Compound Module TCPSpoofingHost

File: Nodes/INET/TCPSpoofingHost.ned

IP host with TCPSpoof in the application layer.

namTrace: NAMTraceWriter notificationBoard: NotificationBoard interfaceTable: InterfaceTable routingTable: RoutingTable tcpSpoof: TCPSpoof networkLayer: NetworkLayer ppp: PPPInterface eth: EthernetInterface

Usage diagram:

The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.

Contains the following modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

EthernetInterface

Ethernet network interface. Corresponds to the prototype NetworkInterface. Complements EtherMAC and EtherEncap with an output queue for QoS and RED support.

InterfaceTable

Keeps the table of network interfaces.

NAMTraceWriter

When placed inside a host or router, it writes a NAM trace, based on notifications it receives via the NotificationBoard. Expects to find a NAMTrace module named "nam" at network level.

NetworkLayer

Network layer of an IP node.

NotificationBoard

Using NotificationBoard, modules can now notify each other about "events" such as routing table changes, interface status changes (up/down), interface configuration changes, wireless handovers, changes in the state of the wireless channel, mobile node position changes, etc.

PPPInterface

PPP interface. Complements the PPP module with an output queue for QoS and RED support.

RoutingTable

Stores the routing table. (Per-interface configuration is stored in InterfaceTable.)

TCPSpoof

Sends fabricated TCP packets. This is a base implementation, you'll probably have to customize it in C++ according to what you want to send and when you want to send it.

Parameters:

Name Type Description
numTcpApps numeric const
numUdpApps numeric const
tcpAppType string
udpAppType string
IPForward bool
namid numeric const
routingFile string

Gates:

Name Direction Description
in [ ] input
out [ ] output
ethIn [ ] input
ethOut [ ] output

Unassigned submodule parameters:

Name Type Description
tcpSpoof.srcAddress string

local address; may be left empty ("")

tcpSpoof.destAddress string

destination address

tcpSpoof.srcPort numeric const

local port number

tcpSpoof.destPort numeric const

destination port number

tcpSpoof.seqNo numeric const

sequence number (-1 for TCP ISS)

tcpSpoof.isSYN bool

whether to set SYN bit on packet

tcpSpoof.t numeric const

simulation time to send at

networkLayer.ip.procDelay numeric const
networkLayer.arp.retryTimeout numeric

number seconds ARP waits between retries to resolve an IP address

networkLayer.arp.retryCount numeric

number of times ARP will attempt to resolve an IP address

networkLayer.arp.cacheTimeout numeric

number seconds unused entries in the cache will time out

ppp[*].queueType string
eth[*].queueType string
eth[*].mac.promiscuous bool

if true, all packets are received, otherwise only the ones with matching destination MAC address

eth[*].mac.address string

MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.

eth[*].mac.txrate numeric

maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured.

eth[*].mac.duplexEnabled bool

whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection).

eth[*].mac.writeScalars bool

enable/disable recording statistics in omnetpp.sca

eth[*].encap.writeScalars bool

enable/disable recording statistics in omnetpp.sca
