Class OSPFMonitor

  +--SSF.OS.OSPFv2.test.OSPFMonitor

All Implemented Interfaces:

SSF.OS.ProtocolMonitor

public class OSPFMonitor

extends java.lang.Object

implements SSF.OS.ProtocolMonitor

Implements a tcpDump utility for OSPF protocol traffic. Some of the code for writing binary tcpdump files is "stolen" from SSF.OS.binaryTcpDump. The monitor is used from an IP session, so it also gets all non-OSPF packets. For simplicity, these are simply ignored.

Field Summary

private java.lang.String	fileName Name of the binary tcpdump file
private SSF.OS.ProtocolSession	ipSession Pointer to the IP session
private java.io.FileOutputStream	outstream File to write the tcpdump to.
private byte[]	rbuf
private int	rct

Constructor Summary

OSPFMonitor()
Constructor.

Method Summary

void	config(SSF.OS.ProtocolSession ownerProtocol, com.renesys.raceway.DML.Configuration cfg) configure the Monitor ProtocolSession[ name ip use SSF.OS.IP monitor[ use SSF.OS.OSPFv2.test.OSPFMonitor file ] ]
private void	dump_ospf_lsa(SSF.OS.OSPFv2.LSA lsa) Dumps a single OSPF LSA
private void	dump_ospf_packet(SSF.OS.OSPFv2.Packet ospfHdr) Dumps an OSPF packet
private void	dump(SSF.OS.PacketEvent pe) Dump a single packet event
private byte	getOspfOptions(boolean[] opts) Creates an OSPF options byte from a bool array
void	init() Initialize the monitor.
private void	raw_commit() Write buffered bytes to the printstream
private void	raw(int len, long val) Write 1, 2, or 4 bytes to buffer in network byte order
private void	rawh(int len, long val) Write 1, 2, or 4 bytes to buffer in host order
private void	rawPacket(SSF.OS.PacketEvent pkt, long atTime) Write raw packet bytes to the output stream.
void	receive(SSF.OS.ProtocolMessage packet, SSF.OS.ProtocolSession fromSession, SSF.OS.ProtocolSession toSession) peek at every IP packet push()ed into IP
private void	write_raw_file_header() Write the generic file header for TCP binary dump files
