get Hostname of the Client connected to the TerminalServer session

9 posts in this topic

This Function gets the Hostname of the Client on the Terminal Server,

can be used to determine the correct std printer near the location of the client while working on the terminal server session.

Func _GetWTSClientName($sid)
Local $result = DllCall("Wtsapi32.dll", "int", "WTSQuerySessionInformation", "Ptr", 0, "int", $sid, "int", 10, "ptr*", 0, "dword*", 0)
If @error Or $result[0] = 0 Then Return SetError(1, 0, "")
Local $ip = DllStructGetData(DllStructCreate("byte[" & $result[5] & "]", $result[4]), 1)
DllCall("Wtsapi32.dll", "int", "WTSFreeMemory", "ptr", $result[4])
Return StringReplace(BinaryToString($ip), Chr(0), "")
EndFunc   ;==>_GetWTSClientName

Best regards,

J

Hi J

Thanks

If i understand this correct this has to be run from a terminalsession and determines the hostname of the computer which runs the terminalsession

Best regards,

What do you mean by "this doesn't work"?

Do you get an invalid result? Do you get an error message? Does your script crash? What operating system does the client run? 32/64 bit? What operating system does the terminal server run? Etc. etc.

Please be more specific - just: "doesn't work" isn't enough to solve a problem

you are right, my fault.

anyway, the doesn't work means there's just " " returned. or maybe anyone has the example for the function?

Im Sorry that i have Witten so less about the Funktion, but i just found it in an Archive of Mine an thought ist could be usefull for you guys, the Funktion returns the hostname if the Client Computer which is connected via rdp on a terminal Server Session, the function Must be called with the credentials of the User currently logged on and be executed on the terminalserver itself.

I use it like $hostname = wtsgetclientname()

$username= @username

And like so you can determine the connected User and the connected client.

Regreat to say that still could not understand the function...and you said, the function must be called with the credentials of the user currently logged on.. but if I, for example:

1. Used User UID1 logon the Server SRV1 from machine PC1

2. Can call the function from PC2 with User UID2 (UID2 is also in the SRV1's local administrators group) to check who has logged on the SRV1 and from Which client?

Im Sorry that i have Witten so less about the Funktion, but i just found it in an Archive of Mine an thought ist could be usefull for you guys, the Funktion returns the hostname if the Client Computer which is connected via rdp on a terminal Server Session, the function Must be called with the credentials of the User currently logged on and be executed on the terminalserver itself.

      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,
      Regards,

      i am trying to figure out how a server can connect to a client Over the internet. 
      In this is script. The client connects to the server on the same machine (localhost) and executes the commands from the client.
      How can I change that instead communicating over localhost to communicate over the internet with tcp ipaddress and a port.
       
      What i actually need help of is
      1. The server will open a port and  listen to communication from a No-ip address
      2. I input the no-ip address and correct port in the client side, and when i click on connect, it connects to the server if its online

      I am working on a code of  Client-Server Connection for a while (Like Teamviewer) , the problem is that the server keeps disconnecting and connecting all the time , In the client i wrote a code to notify me each time server is online , I am getting around 10 notifications each 1 minute from same server :
      This is the server code :
      TCPStartup() Local $ConnectedSocket Local $My_IP = "127.0.0.1" Local $My_PORT = '5000' Local $UserID = "MyID" ; Connect Connect($My_IP, $My_PORT) While 1 If TCPConnect($My_IP, $My_PORT) <> -1 Then $recv = TCPRecv($ConnectedSocket, 2048) $RecvSpl = StringSplit($recv, "|") Switch $RecvSpl[1] Case "order1" ; Do something MsgBox(64,"Success","You are now connected to the client") AddLogToClinet("My server is Online", $UserID, "Green") EndSwitch Else $Connected = False Connect($IP, $My_PORT) EndIf Sleep(100) WEnd ; Connect To the Client Func Connect($IP, $Port) Local $iConnectAttempts = 0 TCPStartup() Do $ConnectedSocket = TCPConnect($IP, $Port) Sleep(1000) Until ($ConnectedSocket > 0 or $iConnectAttempts > 10) Return SetError(@error, 0, $ConnectedSocket) EndFunc ;==>Connect ; Send To Client Func SockSend($Cmd, $Text) TCPSend($ConnectedSocket, $Cmd & $SockSpl & $Text & $PocketSpl, 4) EndFunc ;==>SockSend ; Add Log To Server Func AddLogToClinet($Data, $UserID, $Color) SockSend("AddLog", $Data & $SockSpl & $UserID & $SockSpl & $Color) EndFunc ;==>AddLogToClinet At first the Connection function was : 
      ; Connect To the Client ( Old ) Func Connect($IP, $Port) TCPStartup() $ConnectedSocket = TCPConnect($IP, $Port) If @error Then Connect($IP, $My_PORT) ; <<<<<<<<<<<<<<< This was the causing recursion error Else $Connected = True EndIf EndFunc ;==>Connect It was working  good , except I had 'recursion level has been exceeded  error (old one)

       I've tried  increasing the delay for current code by :
      Opt("TCPTimeout", 5000) However it did not help yet what do you suggest to me ?

      I am working on a desktop remote application so I made a simple server and client to send binary screen captures from client to server. All it's good if I test both scripts on my computer but when the client is in other network many screen shots are corrupted and some of them looks good. Have any idea why?

      Morning all,
      For past few days I've been rattling my brains trying to work out how to create TCP Server and Client. I have successfully made a connection between a single client and server but beyond that I'm hopeless! I've been messing with Arrays and trying to read other examples but it's a little over my head...
      I was hoping I could ask someone to give me a really simple example with some comments for a server to accept multiple connections and a client to connect and receive data from server. I'm planning to have a client and server GUI to display "Client connected with identifier" "Server connected" "Message from server" etc
      Thanks in advance!
