plink connection to remote machine, how to capture StdoutRead outputs as a variable

Recommended Posts

Dear Autoit Forum,

Before I start, I have checked the following topics, but couldn't get far enough:

'?do=embed' frameborder='0' data-embedContent>>

Func _PLINK_Connect($remote, $user, $password)
   Local $hSessionPID = Run("plink.exe -ssh " & $remote & " -l " & $user & " -pw " & $password, "", @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
   If @error Then
      MsgBox(0, "Error: xxx", "Running plink.exe under the main folder failed.")
      Return False
   EndIf
   
   Local $sLine
   While True
      ;read each line
      $sLine = StdoutRead($hSessionPID)
      ;ty_DEBUG print each line after connected
      If $sLine <> "" Then ConsoleWrite("Current Line Start:" & $sLine & @CRLF & "==== Current Line End" & @CRLF)
      If ProcessExists($hSessionPID) = 0 Then
         ConsoleWrite("cannot find PID" & @CRLF)
         Return SetError(9)
      ;check if connected with the given user name
      ElseIf StringInStr($sLine, "Using keyboard") Then
         ConsoleWrite("cannot login" & @CRLF)
         Return SetError(8)
      ;check if connected to remote
      ElseIf StringInStr($sLine, " [cdr2db] :") Then
         ConsoleWrite("connected to remote" & @CRLF)
         ExitLoop
      EndIf
      Sleep(10)
   WEnd
   
   Return $hSessionPID
EndFunc

Now i call the function:

Case1: Everything is fine

_PLINK_Connect("10.25.0.20", "cdr2db", "Cdr2db_1")
Output:
Current Line Start:Last login: Sat Sep 13 12:56:06 2014 from 10.75.58.71


==== Current Line End
Current Line Start:<101 bb1a [cdr2db] :/onip/app/cdr2db>
==== Current Line End
connected to remote

Case2: Another username
_PLINK_Connect("10.25.0.20", "cdr2dba", "Cdr2db_1")
Output:
Current Line Start:Using keyboard-interactive authentication.
Password:
==== Current Line End
cannot login
Using username "cdr2dba".
Access denied

Case3: Wrong password
_PLINK_Connect("10.25.0.20", "cdr2db", "Cdr2db_1a")
Output:
Current Line Start:Using keyboard-interactive authentication.
Password:
==== Current Line End
cannot login
Using username "cdr2db".
Access denied

Case4: Non-existing remote machine
Output:
FATAL ERROR: Network error: Connection timed out
cannot find PID

Now my question is that:

For Case 2 and 3; my last console write says that "current line start / end" then, "cannot login". But in the output window i can find "Using username cdr2db. Access denied". So, how is that output generated?

For Case 4: Even there is no output as ConsoleWrite, how the "FATAL ERROR: ..." line is generated?

I would apperiate any comments on the topic.

Thanks in advance.


TY.

      Hey Guys,

      I have a (i think) simple question, but i can't seem to get the answer though the help-files.
      Hope that you can help me with this issue.
      - I am opening a SSH Connection with the following function
      Func _Connect($session,$usr,$pass) $exec = @ScriptDir & "\PLINK.EXE" If Not FileExists($exec) Then _Err("PLINK.EXE Not Found!",0) $pid = Run($exec & " -load " & $session & " -l " & $usr & " -pw " & $pass, @ScriptDir, @SW_HIDE, 0x1 + 0x8) ;Run SSH.EXE If Not $pid Then _Err("Failed to connect",0) $currentpid = $pid ;$rtn = _Read($pid) ;Check for Login Success - Prompt ;MsgBox(48,"","1") ;sleep(5000) ;Wait for connection Return $pid EndFunc - This will connect to a CMS Server with a vt100 interface where a dynamic report is generated every 20 seconds.
      - Then i will read the contents with the following Function
      Func _Read($pid) $SSHREADTIMEOUT = 0 If Not $pid Then Return -1 Local $dataA Local $dataB Do $SSHREADTIMEOUT += 1 $dataB = $dataA sleep(100) $dataA &= StdOutRead($pid) If @error Then ExitLoop Until ($dataB = $dataA And $dataA And $dataB) OR $SSHREADTIMEOUT == 50 Return $dataA EndFunc This all goes correctly, but i can only read the contents once.
      When i try to read the contents again i get nothing.
      Maybe because the CMS isn't changing, but the values in the report is changing every 20 seconds.
      I need to somehow read al of the contents every time i perform a Read action, but how?
      Yes, i can use it in a While loop, but also then i get nothing or a small line of text and not the whole report.
       
      Any Idea?
       
      Thanks Guys!
       
      --Edit--
      I have fixed the problem by changing the terminal session to a vt220 session.
      The only problem now is that i want to send the: "Data link escape" command and that is something i cannot fix,.
      I have tried;
      StdinWrite($Pid,Hex(0x10)) StdinWrite($Pid,Chr(16)) StdinWrite($Pid,{DLE}) But nothing seems to work.  
      -- Edit-2 --
      Guys, fixed that too!
      Forgot to add the number '5' to actually execute the assignment.
      So fixed it by using;
       
      StdinWrite($Pid,Chr(16)) StdinWrite($Pid,"5")
      Thanks for reading with me

      Hello,
      to provide an easy to use starter to capture traffic on all NICs found, I can successfully get all the interfaces of TSHARK.EXE (the command line version that's automatically installed along with wireshark) with this script:
      #include <AutoItConstants.au3> #include <Array.au3> $TS_WD = "C:\Program Files\Wireshark" $TS_exe = $TS_WD & "\tshark.exe" if not FileExists($TS_exe) Then MsgBox(48,"Fatal Error","No Wireshark Commandline Tool ""TSHARK.EXE"" found:" & @CRLF & _ $TS_exe) Exit EndIf $DString = "" $PIDGetIFs = Run($TS_exe & " -D", $TS_WD, @SW_HIDE, $STDERR_MERGED) While ProcessExists($PIDGetIFs) $DString &= StdoutRead($PIDGetIFs) WEnd ; MsgBox(0,"IFs",$DString) $aNICs = StringSplit($DString, @CRLF, 1) _ArrayDisplay($aNICs) $RegExIF = "^(?:\d+\. )(\\.*?})(?: \()(.*?)(\))$" ; $1 = TSHARK Interface Name, $2 = Windows Interface Name ; ... get the names to run TSHARK with the appropriate interface string  
      When I run TSHARK.EXE using this line directly, I see a continuously growing number telling the number of packets captured so far.
      "C:\Program Files\Wireshark\tshark.exe" -i \Device\NPF_{AEB931E9-E5FA-4DA5-8328-D87BDF53805C} -b duration:300 -b files:600 -w "y:\TShark-Ringbuffer\LAN-Verbindung\TSHARK-Com-0317_17---LAN-Verbindung___.pcap" Using this script, I *DO* see the first output line "Capturing on 'LAN-Verbindung'", but I cannot get hold of the continuously growing number of packets captured so far.
      #include <AutoItConstants.au3> $WD="C:\Program Files\Wireshark" $CMD='"C:\Program Files\Wireshark\tshark.exe" -i \Device\NPF_{AEB931E9-E5FA-4DA5-8328-D87BDF53805C} -b duration:300 -b files:600 -w "y:\TShark-Ringbuffer\LAN-Verbindung\TSHARK-Com-0317_17---LAN-Verbindung___.pcap"' ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $CMD = ' & $CMD & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $PID=Run($CMD,$WD,@SW_SHOW,$stderr_merged) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $PID = ' & $PID & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $OutputAll="" While ProcessExists($PID) $output=StdoutRead($PID) $OutputAll&=$output ToolTip($OutputAll) if $output <> "" then ConsoleWrite("""" & $output & """" & @CRLF) Sleep(1000) WEnd ConsoleWrite("Process vanished" & @CRLF)  
      This is the output of SciTE, when I let TSHARK.EXE run for a short while, the "close" it's "box" ...
       
      --> Press Ctrl+Alt+Break to Restart or Ctrl+Break to Stop @@ Debug(10) : $CMD = "C:\Program Files\Wireshark\tshark.exe" -i \Device\NPF_{AEB931E9-E5FA-4DA5-8328-D87BDF53805C} -b duration:300 -b files:600 -w "y:\TShark-Ringbuffer\LAN-Verbindung\TSHARK-Com-0317_17---LAN-Verbindung___.pcap" >Error code: 0 @@ Debug(13) : $PID = 10948 >Error code: 0 "Capturing on 'LAN-Verbindung' " Process vanished  
      Howto catch the "growing-packet-number" TSHARK.EXE is writing continuously to the same "window position"???

      OK, the odd stuff seems to happen to me. Not sure if this belongs here or in the deployment forum.
      The Question: Why would the console output results from a command-line tool need to know the working dir on one system but not the other?
      Though in the end I solved the issue I still am not understanding why StdoutRead seems to behave differently as I describe below.
      Preamble: Windows 10 image deployment to two different HP workstation hardware platforms. After deployment set up some disk space using Intel RAID. I script the Intel RSTe client (Intel® Rapid Storage Technology enterprise). Same version of the RSTe client and same storage controller hardware (Intel C600+/C220+ series chipset SATA RAID controller). The only difference is in the driver - one system has 4.2.0.1136 and the other has 5.2.0.1194, but even after I update the older driver the anomaly persists. There are of course other differences - the older system has different CPUs (Xeon E5-2620 vs Xeon Silver 4108), different chipsets, different SMBIOS, etc..). Both have Nvidia Quadro cards with driver 385.90, but the older has 3x P2000 cards and the newer has 3x Quadro M4000 and a Quadro K1200.
      To script RAID creation and maintenance I have a function that uses StdoutRead with Intels command line client tool "rstcli64.exe".
      On the older system, the below call to StdoutRead fails. On the newer system, it works. This only started happening on the older hardware when I updated the Windows version 1607 image to build 14393.2189 (but the Windows image used is the same for both hardware targets).
      $s_DoRST = Run(@ComSpec & " /c " & $s_RSTcmd, "", @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD) But if I change it to use @ScriptDir as the working dir, it works for both systems.
      $s_DoRST = Run(@ComSpec & " /c " & $s_RSTcmd, @ScriptDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)  The code below is the one that works on both systems (hint: the comment " ; this only deals with one device" is because I've no hardware with more than one ATAPI device to test with).
      $s_RSTExe = ".\rstcli64.exe" ; for production (compiled executable) ; #FUNCTION# ==================================================================================================================== ; Name ..........: GetDiskInfoFromRSTE() ; Description ...: Queries for hard disks attached to the controller ; Syntax ........: GetDiskInfoFromRSTE() ; Parameters ....: None ; Return value...: An array of attached hard disk datas from the RST command line tool without ATAPI devices such as optical drives ; =============================================================================================================================== Func _GetDiskInfoFromRSTE() Local $s_RSTcmd = $s_RSTExe & " -I -d" Local $s_DoRST, $a_RSTDisksTemp, $s_rawdata, $numDISK = 0 If $Debug <> 0 Then ConsoleWrite("Get disk info: " & $s_RSTcmd & @CRLF) ; useful during dev but cannot be used if #requireadmin $s_DoRST = Run(@ComSpec & " /c " & $s_RSTcmd, @ScriptDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD) ProcessWaitClose($s_DoRST) $s_rawdata = StdoutRead($s_DoRST) $a_RSTDisksTemp = StringSplit($s_rawdata, @CRLF) For $i = $a_RSTDisksTemp[0] To 1 Step -1 ; since we are deleting items, we have to go backwards through the array If $a_RSTDisksTemp[$i] = "" Or $a_RSTDisksTemp[$i] = "--DISK INFORMATION--" Then _ArrayDelete($a_RSTDisksTemp, $i) EndIf Next $a_RSTDisksTemp[0] = UBound($a_RSTDisksTemp) If IsArray($a_RSTDisksTemp) Then For $j = $a_RSTDisksTemp[0] - 1 To 1 Step -1 ; we need to remove the ATAPI device(s), since we delete we have to step through in reverse If StringInStr($a_RSTDisksTemp[$j], "Disk Type: SATA") Then $numDISK = $numDISK + 1 EndIf Next For $j = $a_RSTDisksTemp[0] - 1 To 1 Step -1 ; we need to remove the ATAPI device(s), since we delete we have to step through in reverse If StringInStr($a_RSTDisksTemp[$j], "ATAPI") Then ; we have to delete the ID entry BEFORE and AFTER the ATAPI entry to remove the ATAPI device (always delete from the bottom up!). _ArrayDelete($a_RSTDisksTemp, $j + 1) ; delete entry below _ArrayDelete($a_RSTDisksTemp, $j) ; delete entry _ArrayDelete($a_RSTDisksTemp, $j - 1) ; delete entry above ExitLoop ; this only deals with one device. If there were more we would need to capture all ATAPI device ID locations into another array then delete the original array entries based on the index numbers in the new array. EndIf Next $a_RSTDisksTemp[0] = UBound($a_RSTDisksTemp) If $a_RSTDisksTemp[0] <> 1 Then If $Debug <> 0 Then ConsoleWrite("Found " & $numDISK & " disk(s) attached to controller." & @CRLF) _infoLog("_GetDiskInfoFromRSTE() found " & $numDISK & " disk(s) attached to controller.", $msgSource) Else If $Debug <> 0 Then ConsoleWrite("No disks found to be attached to controller." & @CRLF) _infoLog("No disks found to be attached to controller.", $msgSource) EndIf Else If $Debug <> 0 Then ConsoleWrite("Unable to query RAID controller.

      Hi,
      I would like to automate Putty commands whereby it will select my saved telnet session (so open Putty Configuration and select session) and afterwards it will open the Putty-prompt and will do next commands:
      <Enter>
      ACCESS <Enter>
      'UserName' <Enter>
      SET Priv <Enter>
      'Password' <Enter>
      LOG PORT ALL <Enter>
      And close Putty
      Kind of new in AutoIT so all help is welcome !
       
      Thanks in advance,

      Hi, I'm new.
      Anyways, I'm using the RunBinary.au3 script by trancexx and I want to re-direct the STDOUT of the "child process" back to the autoit script that launches it. I'm attempting to do so using named pipes. If its possible to use StdoutRead instead of namedpipes please let me know. I'm just unsure of how to provide a handle of the childs STDOUT stream to that function. Though DllCall("kernel32.dll", "ptr", "GetStdHandle", "dword", "STD_OUTPUT_HANDLE") seems to get the handle?
      Please excuse any foolish mistakes because I'm new to STDOUT, runbinary and namedpipes. Here's the parts of the code I'm trying to use that are relevent:
      ;~~~Firstly I think I need to make a pipe that's inheritable.. which I may have done wrong Local $_SECURITY_ATTRIBUTES = DllStructCreate("dword Length;" & _ "int lpSecurityDescriptor;" & _ "bool InheritHandle;") ;***Not positive if bool works correctly here? DLLStructSetData($_SECURITY_ATTRIBUTES, "Length", DllStructGetSize($_SECURITY_ATTRIBUTES)) DLLStructSetData($_SECURITY_ATTRIBUTES, "lpSecurityDescriptor", 0) ;***This sets default state; "If the value of this member is NULL, the object is assigned the default security descriptor associated with the access token of the calling process." but I'm unsure if this is what I should use DLLStructSetData($_SECURITY_ATTRIBUTES, "InheritHandle", true);***True = Inheritable(but again I'm not positive the bool works correctly?) Global $hNamedPipe = _NamedPipes_CreateNamedPipe("\\.\pipe\poopp", _;Name 2, _;Direction: 2=both ;I only need 1 direction but I'm just using this for testing 1, _;Flags: 1=no extra instances of pipe are allowed to run 0, _;Security: No ACL Security 0, _;Type: 0=byte 0, _;ReadType: 0=byte 1, _;Wait: 0=Block(wait) 1=No block(no wait) 1, _;Max Instances of pipe allowed 4096, _;out size 4096, _;in size 9000, _;timeout DllStructGetPtr($_SECURITY_ATTRIBUTES));Default=0 which wouldn't make the handle inheritable ;~~~Next I would need to set the STARTUPINFO of the process ;code used by trancexx for the _STARTUPINFO Global $tSTARTUPINFO = DllStructCreate("dword cbSize;" & _ "ptr Reserved;" & _ "ptr Desktop;" & _ "ptr Title;" & _ "dword X;" & _ "dword Y;" & _ "dword XSize;" & _ "dword YSize;" & _ "dword XCountChars;" & _ "dword YCountChars;" & _ "dword FillAttribute;" & _ "dword Flags;" & _ "word ShowWindow;" & _ "word Reserved2;" & _ "ptr Reserved2;" & _ "ptr hStdInput;" & _ "ptr hStdOutput;" & _ "ptr hStdError") ;Attempting to set the values for namedpipe redirection DllStructSetData($tSTARTUPINFO, "Flags", 0x00000100) ;***Flag = STARTF_USESTDHANDLES (I think I set it correctly?) DllStructSetData($tSTARTUPINFO, "hStdOutput", $hNamedPipe) ;***Currently setting the output handle to the SERVER end of the NamePipe I'm creating (which I'm pretty sure is wrong but idk how to use the Client End) ;~~~code used by trancexx for CreateProcess Global $aCall = DllCall("kernel32.dll", "bool", "CreateProcessW", _ "wstr", $sExeModule, _ "wstr", $sCommandLine, _ "ptr", 0, _ "ptr", 0, _ "bool", true, _ ;***changed to inherit handles (not positive I did so correctly) was int 0 before "dword", 4, _ ; CREATE_SUSPENDED ; <- this is essential "ptr", 0, _ "ptr", 0, _ "ptr", DllStructGetPtr($tSTARTUPINFO), _ "ptr", DllStructGetPtr($tPROCESS_INFORMATION)) ;~~~~~Code used in a loop to try to see if anything is being written into the pipe If _IsPressed(35, $hDLL) Then Local $pipeData = _NamedPipes_PeekNamedPipe($hNamedPipe) If @Error Then MsgBox(1,"PipeData Error",@Error & " | " & $pipeData) Else Local $r = _ArrayDisplay($pipeData) If @Error Then MsgBox(1,"Array Error",@Error & " | " & $pipeData) EndIf EndIf  
      I'm not using this exact code cause I changed it around some for the post. I'm mainly wondering how to correctly use the client end of the name pipe? I also had some values I wasn't sure if I set correctly because I don't have experience with com objects. And It seems the process launched needs to be the child?.. Can the process started through the autoitscript can be considered the child process and the script the parent process?
