reverse engineering - How do I change a process's socket connection -

-

A process is connecting to a certain IP or domain, but I do not know what it is. Process can not connect to server How can I find and replace it?

TCPView and netstat are the best work for already installed connections, which is the 'original poster's No status

A better tool for this task is a packet sniffer, which can see the connection effort. I recommend, which is available for all major platforms.

Description:

  1. Install, then start VirusHark
  2. Press Ctrl-K to start capturing
  3. Network Select the interface that you expect to use the program
  4. "tcp [tcpflags] & amp; (tcp-syn | tcp-ack) == tcp-syn" No quote)
  5. Start the capture, try connecting your program, and then stop the capture.

If you do fast in the final step, without any other network activity on one machine, you will only have one captured packet Otherwise, you will need to open a list to find that list This packet will show you the TCP port which you want, which is trying to use the program.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
