how to judge the ftp server is open?

2 posts in this topic

i use ftp.au3 to judge.

=====================================

for example ,ftp://123:123@10.2.72.246:21

#include <ftp.au3>

$ftp_ip = "10.2.72.246"

$ftp_name ="123"

$ftp_pass = "123"

$ftp_ctrlport = "21"

$dllhandle = DllOpen('wininet.dll')

$z_ftpOpen = _FTPOpen('MyFTP_Control')

$z_ftpConn = _FTPConnect($z_ftpOpen, $ftp_ip, $ftp_name, $ftp_pass, $ftp_ctrlport)

If @error Then

MsgBox(0, "ftp", "the FTP is closed or full of users", 5)

$z_ftpClos = _FTPClose($z_ftpOpen)

Else

MsgBox(0, "FTP", "the FTP can be logged in", 5)

$z_ftpClos = _FTPClose($z_ftpOpen)

EndIf

=====================================

but it can judge whether the ftp is closed or it is full of users.

if the ftp is closed ,it will takes a long time to get the result.

how to solve the two problems?

thanks!

I don't know but I would expect that you can't tell. Whichever problem exists there will be no reply from the ftp server so maybe that's all you can say.

It is possible that a call to InternetGetLastResponseInfo will give you the reason for the failure though.

I expect the msbox lines were put in when I was playing with this once. I don't know where the function comes from or who wrote it.

; Use InternetGetLastResponseInfo when GetLastError returns ERROR_INTERNET_EXTENDED_ERROR.
Func _InternetGetLastResponseInfo($LeHD,ByRef $LstErr,ByRef $ErrStrg)
    
        msgbox(0,'getting last response info','')
#cs 
    $Res = DllCall ("wininet.dll", "int", "InternetGetLastResponseInfo",  "str", "",  "str", "", "int", 0 )

; The empty strings gets filled by the function, so we can get their values
$LstErr = $Res[1]
$ErrStrg = $Res[2]
    
#ce
    
    $struct_Buffer = DllStructCreate("char[300]");

    $erBuf = DllStructCreate('int')
    $szBuf = DllStructCreate('int')
    DllStructSetData($szBuf,1,300)
    $Res = DllCall($LeHD,'int', 'InternetGetLastResponseInfo','int*',DllStructGetPtr($erBuf),'ptr',DllStructGetPtr($struct_Buffer),'int*',DllStructGetPtr($szBuf)
    $LstErr = DllStructGetData($erBuf, 1)
    $ErrStrg = DllStructGetData($struct_Buffer, 1)
    msgbox(0,'size requested is',DllStructGetData($szBuf,1))
    msgbox(0,'LstErr = ' & $LstErr,'Error message = ' & $ErrStrg)
    if @error = 1 then msgbox(0,'dll failed','')
        msgbox(0,'ftpplus 750. err string is',$ErrStrg)
    $rreess = ''
    for $rr = 0 to UBound($res)- 1
        $rreess = $rreess & $res[$rr] & @CRLF
    Next
    msgbox(0,'From lastresponse',$rreess)

    return $Res;[0]
EndFunc
