Class RandTraces

java.lang.Object
  |
  +--RandTraces

public class RandTraces

extends java.lang.Object

This class gets the result of a remote traceroute and shows it on stdout. Calling the constructor runs the traceroute. After I get good at it, there will be methods to ask for the ping time, hop count, delay variance, and (if I get really ambitious) list of AS Numbers traversed. The inputs are source = the remote node performing the traceroute, dest = the name of the target of the traceroute. cmd = the URL snippet that asks the server to run traceroute.

Constructor Summary

RandTraces(java.lang.String source, java.lang.String cmd, java.lang.String dest)
construct a traceroute from source to dest.

Method Summary

static void	main(java.lang.String[] args) test the GetTraces features.
boolean	receiveTraceInfo(int tracingAS, java.io.BufferedReader in, int ultimateAS) reads the result of the HTTP GET line by line, looking for anytbing that looks like a traceroute.
void	runTrace() opens a socket to the trace host and ask for a traceroute.
