Debugging with PyCharm¤

In order to debug code with PyCharm you need to configure remote debugging.

PyCharm will start a remote debugging server which will listen for connections and pwndbg will then connect to that server, on startup.

Configuring the debugging server¤

Select Run -> Edit Configurations and follow the instructions there :)

  • Create a new server with the + button.
  • Put your IP in IDE host name and select a port number.
  • Optionally, add a path mapping: pycharm/pwndbg/dir=machine/pwndbg/dir
  • Uncheck suspend after connect

Configuring pwndbg¤

  • Select Run -> Edit Configurations and install the packages described in that window.
  • pip install pydevd-pycharm~=<your_pycharm_version>
  • Add the following code somewhere where it will execute on gdb startup: 
    1
2
    import pydevd_pycharm
pydevd_pycharm.settrace('<your_IP>', port=<port>, stdoutToServer=True, stderrToServer=True)

Debugging¤

  1. Start the debugging server in PyCharm
  2. Run pwndbg

WSL2¤

In order to debug using WSL2, you need to obtain your Windows IP. The easiest way to do that is to run: 

1
cat /etc/resolv.conf
and then to pick the value in the nameserver line. Then use that IP in the IDE host name field, when configuring the server. Afterwards, use the same IP in pydevd_pycharm.settrace(...)
