If the service adds a small input sanitisation (e.g., read truncates at newline), you can replace the newline with a null byte ( \x00 ) and send the exact length using sendall (the read system call ignores \n ). In practice the above works because the service reads raw bytes and the newline is just part of the payload. tokyohot n0541
