Code updated for 5.20+

Here is a source code for tracert.

Code: Select all

EchoMessage.s = "echo" 
ResultSize.l = SizeOf(ICMP_ECHO_REPLY) + Len(EchoMessage) 
*Result = AllocateMemory(ResultSize) 
*Echo.ICMP_ECHO_REPLY = *Result

ip_option.IP_OPTION_INFORMATION
  
sIPAddress.s = "216.239.59.103" ; www.google.com
    
If Len(sIPAddress ) > 0 
  hFile.l     = IcmpCreateFile_() 
  IPAddress.l = inet_addr_(sIPAddress)

  For ttl_int = 1 To 255

    ip_option\Ttl = ttl_int

    Echo_Result.l = 0
    counter.l     = 0
        
    While Echo_Result = 0 And counter < 3
      counter + 1
      Echo_Result = IcmpSendEcho_(hFile, IPAddress, EchoMessage, Len(EchoMessage), ip_option, *Result, ResultSize, 1500) 
         
      If Echo_Result = 1
        Debug "address : " + IPString(*Echo\Address)
        Debug "rtt     : " + StrU(*Echo\RoundTripTime, 2)
        
        If *Echo\Status = 0 : Break 2 : EndIf
      EndIf
 
    Wend
        
    If Echo_Result = 0
      Debug ("unknown address")
    EndIf

    Debug "-----------------------------"

  Next

  IcmpCloseHandle_(hFile) 

EndIf 
    
End

Awesome, Thanks very much

When i saw the title i thought you had just captured the output from cmd's tracert command but this is very good, now we just need to add a dns hostname resolver and we will be all set :)

I could find quiet a few uses for this, again good work!

Cool, thank you!
And like Tommeh said, a DNS resolve would be nice. :D

Now with IP address name.

Could you add the ability to do the same thing with the
adress: www.google.com instead of the ip ?
By adding a litle text field next to the ip adress one...

Thank's

I use this function in the source below:

Code: Select all

Procedure.s GetIPAddress(servername.s,port.l); <- Obtener la IP dado el nombre de dominio (por la forma PB sin API externa):
  Protected connectionID.l=OpenNetworkConnection(servername,port)
  If connectionID=0:MessageRequester("error","Error opening connection"):ProcedureReturn "":EndIf
  servername.s=IPString(GetClientIP(connectionID))
  CloseNetworkConnection(connectionID)
  ProcedureReturn servername.s
EndProcedure
which is valid also for Linux for example.
But there are other using sockets which is faster, like:

Code: Select all

Procedure.s GetIpAddr(ComputerName.s); <- obtiene la IP de un nombre de host (convierte hostname en IP)
  If ComputerName
    If WSAStartup_($0101,wsa.WSADATA)=#NOERROR ; Try to access Windows sockets stuff...
      *host.HOSTENT=gethostbyname_(ComputerName) ; Get host information for named computer...
      WSACleanup_() ; Close Windows sockets stuff...
      If *host
        ProcedureReturn PeekS(inet_ntoa_(PeekL(PeekL(*host\h_addr_list))))
      EndIf
    EndIf
  EndIf
  ProcedureReturn "Unable to get IP"
EndProcedure

If you are willing to go Win2k and newer only, you can also use this one for the
dns lookups: http://www.purebasic.fr/english/viewtop ... 886#182886

It is of course faster than first establishing a connection before getting the IP.
The reverse lookup also seems faster than the gethostbyaddr_() used in the trace, so it could speed it up a bit more.
