Hi,
I would like to send an array from a script to a another. This array has 1000 rows and 4 columns with this kind of data :
1st row = 528 ; 31 ; HOSTNAME|1|02:45:47|abcdefgh|username|5 ; old
2nd row = ...
What IPC should I use ?

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"???
Regards, Rudi.

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. Check hardware and version of RST client software." & @CRLF) _errorLog("Unable to query RAID controller.

I was in need of an IPC (Interprocess communication) between system, admin and user levels, and ended up writing this UDF to suit my wantings.
Hope you find it useful too.
Works from WinXP/Server2003 to the now current Win10/Server2016.
It communicates between any mix of x32, x64, Admin, User.
In the zip file, there is the UDF and an example: FMIPC(v0.2018.04.04).zip
Special thanks to @RTFC for the help in the support forum
