Stuck at level 91? (Server fault?)

Bizarre - the exact same command works fine on my friend's computer, just not on mine

I'll try the script and see what happens.

EDIT - nope, the CURL command still fails, telling me that I need the solution to be 4 characters long... I'm now having this problem with all the levels, not just 106 onwards

I suspect you have some login session problem or something similar.
"The answer is 4 characters long" possibly means that level 0 is loaded, and "The answer is 1024 characters long" should be the proper length for 106.
My method for puzzle automation is to log in to the forum first and then load the puzzle page.

I've tried that

ah well - might just be a problem with my cURL (not the latest version) - I'll update it and see.

Try to use gotolevel instead of lvl for submitting the solution.
The server doesn't seem to care about the lvl parameter.

Still nothing - the ContentLength is correct, all the data are marked by cURL as going out correctly (adding the --trace option shows that the entire solution is actually submitted) - yet it works fine on a different computer :/ Problem is that my solver is in Mathematica, calling cURL on the command line; I can't use the Mathematica solver on another computer because it's a one-person license

have you tried using something different to send your solution, like wget?
Not that it makes much sense, but it may be some strange bug involving curl and your local configuration...

Bizarrely, wget works fine

thanks for the help, people!

i got stuck at 91 too, then i changed my code to use post rather then get

Code: Select all

private void go() throws Exception {
		URL u;
		BufferedReader rd;
	   String enc="UTF-8";
		u = new URL("http://www.hacker.org:80/cross/index.php");
		URLConnection conn=u.openConnection();
		conn.setDoOutput(true);
		conn.setRequestProperty("Content-Type",
            "application/x-www-form-urlencoded");       
		try (OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream())) {
			if (sol.isEmpty()) {
				writer.write("name=" + URLEncoder.encode(name, enc) +
					"&password=" + URLEncoder.encode(pw, enc));
			} else {
				writer.write("name=" + URLEncoder.encode(name, enc) +
					"&password=" + URLEncoder.encode(pw, enc) +
					"&sol=" + sol);
			}
			writer.flush();
			rd = new BufferedReader(new
			InputStreamReader(conn.getInputStream()));
			input2level(rd);
		}
		rd.close();
		System.out.println(this);
		solve();
		System.out.println("Sol: "+sol);
	}

I also got up to lvl 91. Now the solution is too long for get and I don't know how I can implement a post submission, Can someone give me an example how to submit the result with post rather than get.

Thanks,

In this Thread, there is one Solution using Java and one using Bash - just use one of these.

I am looking for a way in c or c++, cause I coded my bot iin c++. I have never programmed sth. like this before, so is there anyone who can help me?

people know about matrix manipulation stuff but fail with such a primitive thing as a http_post request? serious facepalm.

Post isn't very primitive - matrix manipulation can be worked out with pencil and paper, while Post can't.

If you're using C/C++ for this then you probably want to check out the Curl library. Unfortunately I haven't used it myself so I can do little more than point you in its direction.

actually you should almost be able to do a http_post request via telnet only. you need it everywhere ... from benchmarking, manipulating online games, automating stuff on the web, programming apps, using rest/oauth/etc. apis, writing a webspider, writing pentest tools, debuging websites, etc. ... it is hard for me to acceppt that anyone playing "hacker.org" games would not know how to do something primitive as this. i am not meaning to be rude it just sounds weird to me. it is like you are writing new software for your car's ECU not knowing how to change tires.
