Getting Started To get your feet wet with pwntools, let’s first go through a few examples. That way, you can (transparently) send binary data to a Pwntools Python Library In the vast realm of software engineering, libraries and tools Tagged with exploitdevelopment, pwntools, exploitdev, ethicalhacking. By default, a pty is used so that any stdout buffering by libc routines is disabled. fileno() If your GDB uses a different Python interpreter than Pwntools (for example, because you run Pwntools out of a virtualenv), you should install rpyc package into its sys. Contribute to Gallopsled/pwntools development by creating an account on GitHub. The returned PID (s) depends on the type of target: str: PIDs of all processes with a name matching target. The file is cached in /tmp/pwntools-ssh-cache using a hash of the file, so calling the function twice has little overhead.
