hacker.org

this is a nice one!

I first tried to fetch the one.php but got only a 404 error.
with lynx -head I finally got the whole header with the answer

I used Fiddler 2. It was easier then I thought, still I screwed a lot of time with it. I had the headers a long time ago when somewhere a rad that the answer is there. I was searching for the content of one.php, thought Fiddler is an idiot not seeing it, after all I was the idiot not trusting him.

The instructions had the fault, it was saying not to blink, but if the headers were containing the answer, no matter what, you couldn't see it with a browser.

I use LiveHTTP Headers extension, for Firefox.

i used Wireshark a network protocol analyzer

i used Tamper Data Plugin for Firefox

No need for fancy graphical tools

I used tcpdump under mac os x' terminal.

wget -S -O - http://www.hacker.org/challenge/misc/one.php

wget --server-response http://www.hacker.org/challenge/misc/one.php

Nice challenge, my favourite till now...

I used telnet myself

First i was confused how to get the one.php.
Then i just read its header with the web console
build into the firefox beta.

I wrote an HTTP request.

I solved with consciousness by writing HTTP request in telnet
and finally found the answer in the header. Actually I should have
solved it when I was using wget and it takes me one extra day

A valuable lesson for me: A good hacker have to read carefully

But very nice challenge! I've learnt a lot!

I solved this nice one by telnet.

I solved it with wget. I don't make sense. But anyway, I was done
