Hi I have an idea of creating a parental filter (freeware) , which will be protecting children from navigating to adult websites. I want to ask, what is your opinion, how to do it best way?
How to catch the traffic from the very beginning?
For example if a user is starting IE or Firefox, or if he has some alternate BLABLA-browser - how can I catch the url before actual navigation to website, so that my script could first check if the website is ok, and then if it decides that the website is not ok, just block connection to this IP.
Looking forward to your opinions, Great thanx in advance!
TCP port forwarding
Hello everyone. I'm wondering if its possible:
I want to try create a simple autoit script that will
1) first he must connect to some IP in internet port 80
2) then he must listen for incoming connections from other IP'S ports 8000 - 8200 [in total over 200 connections]
3) that script must send all recieved data from that [IP in internet port 80 ] to [other IP'S ports 8000 - 8200]
is that very hard to do ? Any suggestions or maybe some similar examples that can help me to do this ?
all those 200 connections must receive data at the same time at once is it possible to do so ?
Unstable TCP socket connection server keeps disconnecting and connecting all the time
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 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?

I'm trying to create a small program that would allow me to send files across my network, therefore, I copy pasted the code available right here.
I modified the code a little to suit my needs, it is in the spoiler below:
So I ran the program, clicked on "Wait for file" on my main computer, ran it again on my other computer, chose a fie, and I set the IP to the one of my first computer (192.168.x.x).
However, the I only get a loading time, and a WSA error 10060 (Time out).
I double checked with the examples of the official autoit doc, but unfortunately, I have no idea where my mistake is..
Do you guys have any idea?
EDIT: removed unnecessary code
