It was provided to you already. Slow down and go back to the very beginning where you downloaded the zip file and read the instructions carefully.
i have no idea what the docker host thing is for, can anybody tell me.
Hi!
Iâm very new in this topic. I found the vuln in the bin but the question is how do I run the program in the server instance?
Thank you in advance!
I started the instance and got the host IP and port and copied it to a web browser but it says: This page isnât working
178.62.7.66 sent an invalid response.
ERR_INVALID_HTTP_RESPONSE
Where do I go from here?
Continuing the discussion from Official racecar Discussion:
same for me Remote host HTTP protocol error, do u find a solution?
racecar file give me an error on Mac and linux
bash: ./racecar: No such file or directory
Try any of these (remember the space b/n host and port) -
- nc host port
- netcat host port
For any other beginners that are getting stuck on the canât open flag or ./racecar: No such file or directory. Make sure you have downloaded the appropriate tools and packages. Good Luck!
A note for anyone on a Mac with Apple Silicone (M1/2/3), the binary is compiled for intel chips so it will not run on Apple silicon/ARM systems.
Cool challenge long time no see this bug in challenge, anyone need dm me ^^
For Beginners like myself, if you get an Error stating [-] Could not open flag.txt. Please contact the creator create a new text file in the same dir named âflag.txtâ and if youâre in Ghidra and or Cutter set mode to read-only 
Solved the racecar challenge, It was a bit difficult for me as I am new to security. I had to take help of walkthrough. But got the flagâŚHurray!!!
Hi,
i have never done a reverse engineering challenge or anything similar.
I think I start to understand what the program does, but have no clue how to manipulate its behavior based on user input.
Can you recommend what topics to read/learn about in order to crack this challenge?
Are there any modules on the academy that relate to this?
Thank you!
