Robot form submission – Part 2

Ankit wrote a nice post about using Java to fill up a form, which is a FCFS allocation (can’t they just *provide* a quantity of good courses?). However, filling up the form can be simply done by a Firefox extension, Autofill forms; but what I would really like to do is be sleeping while the course registration goes on. πŸ˜€

Ingredients: Firefox, bash, curl, a bit of common-sense

1) First of all, install two Firefox extensions – Web Developer and Firebug.

2) Fill up the form that you’re going to fill up. (don’t get lost in recursion here!)

3) Follow the screenshot below and convert POST to GET.

4) Now open up Firebug console (press F12), select the Net tab, and enable it.

5) Now click on Submit:

Ignore the “Registration is currently closed”, look at the console, you’ll have a big url that corresponds to your choices, just copy it.

It will be of the form:


6) To simulate this form submission, you’ll need this command:

curl <url> -d <data> -k -L

7) However, there is a problem, you have to authenticate first. No sweat:

curl https://isas/validate.php -d ‘StUdent=username&searchin=200&password=password&submit=Submit’ -c cookies.txt -k -L

This will save the login cookies in a file named cookies.txt

8) So now we finalize the script:


while (( 1 ))


curl https://isas/validate.php -d ‘StUdent=username&searchin=200&password=pass&submit=Submit’ -c cookies.txt -k -L #Change username and pass accordingly

curl https://isas/registration/updateSpecialReg.php -d <data> -k -L -b cookies.txt

sleep 5s #We don’t wanna hammer the server down :)


While I sleep on. :)

PS0: If you can’t get this to work, read about HTTP 402.

      Why do you all ppl abide by the rules of isas ?

      I remember a quote from “Matrix”:

      These rules are no different than those of a computer system.

      Some of them can be bent.

      Others . . .

      . . . can be broken.

        @Ajay So you were sleeping while the registration was going on?
        @Dr. Manhattan Sorry dude, information about SQL injections might be dangerous so I had to edit your comment.

    Curious to know wht happens to ISAS the next sem and who gets what course if every one uses the same script (except the one having more smarter Hacks πŸ˜€ )… I guess , it’ll finally be down some random allocation :)
