[PWN] Dream Diary [SOLVED]

Hi, I have a problem with this challenge. I can run the exploit locally (loading the binary with what I assume being the right libs…) but can’t manage to make it work remotely. How is the challenge actually deployed ? The remote binary behavior seems different from the one running locally. For instance every input is echoed back by the server. Is there a different binary on remote? Or some sort of proxy in between doing it ? Thanks in advance
