TraceRoute Component

Properties   Methods   Events   Configuration Settings   Errors  

The TraceRoute component allows you to trace the path IP packets take on the Internet.

Syntax

TipwTraceRoute

Remarks

The component implements a standard IP Traceroute as defined in RFC 1393.

To use the component, simply call the TraceTo method and set the Host parameter to the domain name or IP address of the host you want to trace the path to. This is identical to setting the RemoteHost property to the domain name or IP address. The component will start sending probe packets towards the host, and as it receives replies it will fire Hop events giving information about the route. The same information is also provided in the Hops properties.

The ResolveNames property enables or disables DNS resolution of IP addresses received during the trace. If set to False only IP addresses are provided. If set to True the component will attempt to resolve the names of the hosts in the route. This may considerably increase the time it takes to complete the trace.

The HopTimeout property determines the maximum waiting time for a response in each hop of the trace, while the Timeout property defines the maximum waiting time for the whole trace. The HopLimit property specifies the maximum number of hops allowed for a trace.

HopLimit Property (TraceRoute Component)

The maximum number of hops to allow for a trace.

Syntax

__property int HopLimit = { read=FHopLimit, write=FSetHopLimit };

Default Value

64

Remarks

This property is used to limit lengthy traces. A value of 0 indicates an unbounded trace.

Note: if the value of Timeout is 0, an unbounded trace may cause a call to TraceTo to block indefinitely. To cancel such a route trace, call Interrupt.

Data Type

Integer

HopCount Property (TraceRoute Component)

The number of records in the Hop arrays.

Syntax

__property int HopCount = { read=FHopCount };

String

HopHostAddress Property (TraceRoute Component)

The IP address of the host for a particular hop in the trace.

Syntax

__property String HopHostAddress[int HopIndex] = { read=FHopHostAddress };

Default Value

""

Remarks

The IP address of the host for a particular hop in the trace.

The HopIndex parameter specifies the index of the item in the array. The size of the array is controlled by the HopCount property.

This property is read-only and not available at design time.

Data Type

String

HopHostName Property (TraceRoute Component)

The name of the host for a particular hop in the trace.

Syntax

__property String HopHostName[int HopIndex] = { read=FHopHostName };

Default Value

""

Remarks

The name of the host for a particular hop in the trace.

If ResolveNames is False, this property contains the IP address of the host instead.

The HopIndex parameter specifies the index of the item in the array. The size of the array is controlled by the HopCount property.

This property is read-only and not available at design time.

Data Type

String

HopTime Property (TraceRoute Component)

The amount of time taken by a particular hop in the trace.

Syntax

__property int HopTime[int HopIndex] = { read=FHopTime };

Default Value

0

Remarks

The amount of time taken by a particular hop in the trace. If a given hop times out, this value will be set to -1.

The HopIndex parameter specifies the index of the item in the array. The size of the array is controlled by the HopCount property.

This property is read-only and not available at design time.

Data Type

Integer

HopTimeout Property (TraceRoute Component)

Maximum amount of time to wait for an individual hop to complete.

Syntax

__property int HopTimeout = { read=FHopTimeout, write=FSetHopTimeout };

Default Value

10

Remarks

The time value is in seconds. If 0, HopTimeout will be ignored, and only the Timeout for the whole trace will be taken into account.

Data Type

Integer

Idle Property (TraceRoute Component)

The current status of the component.

Syntax

__property bool Idle = { read=FIdle };

Default Value

True

Remarks

Idle will be False if the component is currently busy (communicating and/or waiting for an answer), and True at all other times.

This property is read-only.

Data Type

Boolean

LocalHost Property (TraceRoute Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

Default Value

""

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

RemoteHost Property (TraceRoute Component)

The address of a host to trace to.

Syntax

__property String RemoteHost = { read=FRemoteHost, write=FSetRemoteHost };

Default Value

""

Remarks

Traces are initiated by setting RemoteHost to the name or address of the host to trace to.

This property must contain a valid Internet domain name or address or an error will be returned.

To interrupt a trace in progress, set RemoteHost to empty string.

Example (Perform a TraceRoute)

TraceRouteControl.TraceTo("myHost") is equivalent to TraceRouteControl.RemoteHost = "myHost"

Data Type

String

ResolveNames Property (TraceRoute Component)

Determines whether the component resolves the host name for each host during the trace.

Syntax

__property bool ResolveNames = { read=FResolveNames, write=FSetResolveNames };

Default Value

False

Remarks

This property determines whether the component resolves the name of host at each "hop" during the trace. The default value is "False". Please note that the trace takes longer due to name resolution if this property is set to "True".

Data Type

Boolean

Timeout Property (TraceRoute Component)

A timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the component will wait for the operation to complete before returning control.

The component will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the component raises an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

Config Method (TraceRoute Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoEvents Method (TraceRoute Component)

Processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (TraceRoute Component)

Interrupt the current method.

Syntax

void __fastcall Interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

Reset Method (TraceRoute Component)

Reset the component.

Syntax

void __fastcall Reset();

Remarks

This method will reset the component's properties to their default values.

ResolveRemoteHost Method (TraceRoute Component)

Resolves the hostname in RemoteHost to an IP address.

Syntax

void __fastcall ResolveRemoteHost();

Remarks

This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.

In most cases calling this method is not necessary, the component will resolve the hostname automatically when necessary. If DelayHostResolution is true this method may be called to manually resolve RemoteHost if desired.

TraceTo Method (TraceRoute Component)

Trace the route to a host.

Syntax

void __fastcall TraceTo(String Host);

Remarks

Traces are initiated by calling TraceTo, with the Host argument set to the name or address of the destination host to trace to. Host must contain a valid Internet domain name or address, or the component raises an exception. To interrupt a trace in progress, set RemoteHost to empty string. Calling this method is equivalent to setting the RemoteHost property to Host.

Example (Perform a TraceRoute)

TraceRouteControl.TraceTo("myHost") is equivalent to TraceRouteControl.RemoteHost = "myHost"

Error Event (TraceRoute Component)

Information about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;

  String Description;

} TipwTraceRouteErrorEventParams;

typedef void __fastcall (__closure *TipwTraceRouteErrorEvent)(System::TObject* Sender, TipwTraceRouteErrorEventParams *e);

__property TipwTraceRouteErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Hop Event (TraceRoute Component)

Fired for each hop in the trace to the RemoteHost .

Syntax

typedef struct {
  int HopNumber;

  String HostAddress;

  int Duration;

} TipwTraceRouteHopEventParams;

typedef void __fastcall (__closure *TipwTraceRouteHopEvent)(System::TObject* Sender, TipwTraceRouteHopEventParams *e);

__property TipwTraceRouteHopEvent OnHop = { read=FOnHop, write=FOnHop };

Remarks

This event provides access to the information for each hop in the trace. The HopNumber parameter denotes which hop the trace is at. The HostAddress parameter is the IP address of the host for the hop identified by HopNumber. The Duration parameter shows the amount of time taken by the hop.

HopResolved Event (TraceRoute Component)

Fired when the name of a hop address is found.

Syntax

typedef struct {
  int HopNumber;

  int StatusCode;

  String HopHostName;

} TipwTraceRouteHopResolvedEventParams;

typedef void __fastcall (__closure *TipwTraceRouteHopResolvedEvent)(System::TObject* Sender, TipwTraceRouteHopResolvedEventParams *e);

__property TipwTraceRouteHopResolvedEvent OnHopResolved = { read=FOnHopResolved, write=FOnHopResolved };

Remarks

The StatusCode contains 0 if the address is resolved successfully, or an error code, in which case, HopHostName contains a textual description of the error.

Host name resolution is disabled by default. Set ResolveNames to True to enable it.

Configuration Settings (TraceRoute Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

TraceRoute Configuration Settings

DelayHostResolution:   Whether the hostname is resolved when RemoteHost is set.

This setting specifies whether a hostname is resolved immediately when RemoteHost is set. If true the component will resolve the hostname and the IP address will be present in the RemoteHost property. If false, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may called to manually resolve the value in RemoteHost at any time.

The default value is false.

HopTimeoutInMilliseconds:   The hop timeout is treated as milliseconds.

Setting HopTimeoutInMilliseconds to true causes the component to use the value in the HopTimeout property as milliseconds instead of seconds, which is the default.

TimeoutInMilliseconds:   The timeout is treated as milliseconds.

Setting TimeoutInMilliseconds to true causes the component to use the value in the Timeout property as milliseconds instead of seconds, which is the default.

ICMPPort Configuration Settings

DelayHostResolution:   Whether the hostname is resolved when RemoteHost is set.

This setting specifies whether a hostname is resolved immediately when RemoteHost is set. If true the component will resolve the hostname and the IP address will be present in the RemoteHost property. If false, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may called to manually resolve the value in RemoteHost at any time.

The default value is false.

DontFragment:   Whether the DontFragment control flag is set.

When set to true the DontFragment control flag in the IP header will be set.

The default value is false.

IcmpDllTimeout:   The timeout for the component when using the icmp.dll.

The component will wait for the operation to complete before returning control. If IcmpDllTimeout expires, and the operation is not yet complete, the component raises an exception. IcmpDllTimeout must be set to a positive value.

The default value for IcmpDllTimeout is 60 seconds.

NOTE: This setting is only valid when UseICMPDLL is set to true.

MaxMessageSize:   The maximum length of the messages that can be received.

This setting specifies the maximum size of the datagrams that the component will accept without truncation.

MulticastTTL:   The time to live (TTL) value for multicast ICMP packets sent by the component.

When sending multicast packets, the setting specifies the Time-To-Live (TTL) field. The Time-to-live (TTL) field of the ICMP packet is a counter limiting the lifetime of a packet.

Each router (or other module) that handles a packet decrements the TTL field by one or more if it holds the packet for more than one second, thus the TTL is effectively a hop count limit on how far a datagram can propagate through the Internet. When the TTL is reduced to zero (or less), the packet is discarded.

By default, the default TTL value of the underlying TCP/IP subsystem will be used.

ReceiveAllMode:   Enables a socket to receive all IPv4 or IPv6 packets on the network.

This setting specifies the ReceiveAll mode for the socket. Available modes:

ValueDescription
-1 (default)The socket option is left unspecified.
0Do not receive all network traffic.
1Receive all network traffic. This enables promiscuous mode on the network interface card (NIC). On a LAN segment with a network hub, a NIC that supports promiscuous mode will capture all IPv4 or IPv6 traffic on the LAN, including traffic between other computers on the same LAN segment.
2Receive only socket-level network traffic (Feature may not be implemented by your Windows installation).
3Receive only IP level network traffic. This option does not enable promiscuous mode on the network interface card. This option only affects packet processing at the IP level. The NIC still receives only packets directed to its configured unicast and multicast addresses. However, a socket with this option enabled will receive not only packets directed to specific IP addresses, but will receive all the IPv4 or IPv6 packets the NIC receives.

TimeoutInMilliseconds:   The timeout is treated as milliseconds.

Setting TimeoutInMilliseconds to true causes the component to use the value in the IcmpDllTimeout config as milliseconds instead of seconds, which is the default.

NOTE: This setting is only valid when UseICMPDLL is set to true.

UseConnection:   Determines whether to use a connected socket.

UseConnection specifies whether the component should use a connected socket or not. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional TCP sense. What it means is only that the component will send and receive data only to and from the specified destination.

The default value for this setting is False.

UseICMPDLL:   Use the icmp.dll included on Windows Systems.

Setting UseICMPDLL to true causes the component to use the icmp.dll on Windows 9x or later machines. This sometimes enables access to raw sockets when permissions for standard operations are prohibited.

UseIPHLPDLL:   Use the iphlpapi.dll included on Windows Systems.

Setting UseIPHLPDLL to true causes the component to use the iphlpapi.dll on Windows XP or later machines. This sometimes enables access to raw sockets when permissions for standard operations are prohibited. Note that if both this and UseICMPDLL are enabled, the iphlpapi.dll will take precedence.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the component will use IPv4 exclusively. When set to 1, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

Socket Configuration Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Configuration Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation.

By default the component will use the system security libraries to perform cryptographic functions. Setting this to True tells the component to use the internal implementation instead of using the system's security API.
