logger

protected Logger logger

Logging

UNREACHABLE_HOST_IP

public static final String UNREACHABLE_HOST_IP

Standart ip for an host which is unreachable ie. a timeout occred

Constant Field Values

UNREACHABLE_HOST_NAME

public static final String UNREACHABLE_HOST_NAME

Standart host name for an host which is unreachable ie. a timeout occred

See Also:

Constant Field Values

MAX_UNREACHABLE_HOSTS

public static final short MAX_UNREACHABLE_HOSTS

Number of left out hosts which are unreachable (ie. a timeout occured). Some hosts doesn't respond when they receive a ICMP message because of their firewall. In this case they are left out and a standard entry is added to the result.

Constant Field Values

MAX_RETRIES

public static final short MAX_RETRIES

Number of tries for an unreachable host ie. timeout

See Also:

Constant Field Values

timeOut

protected int timeOut

time out in ms between sending and receiving of a packet

maxHops

protected int maxHops

The number of maximum steps to a target host.

targetHost

protected String targetHost

The ip adress of the target host in string representation.

Method Detail

traceRoute

protected abstract Vector traceRoute(int maxHops,
                                     int timeOut,
                                     String target)
                              throws TraceRouteException

The traceroute method, which has to be implemented.

Parameters:

maxHops - The maximum number of hops between the source and targed host

timeOut - The time in ms between sending and receiving of a request

target - The target host IP in string representation (xxx.xxx.xxx.xxx)

Returns:

a Vector containing the IPs as strins

Throws:

TraceRouteException

abort

protected void abort()

Cancle the execution as soon as possible.

isCancled

protected boolean isCancled()

Test if the execution was cancled.

Returns:

True if trace is cancelled.
