Filling a form spambot style.

My ISP uses a html client , So to do a 'login' i have to goto a page like this:
http://203.122.xx.xxx:8886/portalcgi...=00:xx.xx.x..x..
fill-in the username,password and thats it!
The trouble is that this has to be done after every 30 minutes of inactivity :( , and this totally confuses my computer-noob parents

So i was wondering if I could automate this. i.e run a lil program that would go the specified page a fill in the username and password fields

The first that comes to my mind are those spam-bots that are able to fill in forms, wreak comment systems. Unfortuantely I am anything but leet, so i have really no idea how to even begin. i am not a programmer though I am aware of basics of plenty of languages, so i could probably write something myself if there is a lil help.

Any suggestions?

relevant code from the source code.

Code:

---

<td > <input type="text" id="username" name="username" value="">

---

Thanks

My first suggestion is that is not the way to go:eek:

This "problem" used to be pretty common back in the early days of the internet and dial up connections. The solution was to instal a little proggy that "talked" to the ISP and reset the "clock"

I don't know if you can find one these days as it is pretty unusual behaviour for 2007.

You might talk to the ISP and ask their advice? For example, can't you just save the settings and login so all they have to do is click on an icon and it will redial?

EDIT: If they pulled that kind of stunt on me they would lose a customer so fast their feet wouldn't touch the ground! I would get a different ISP if I were you. This may help, depending on your system:

Thanks for the quick reply, i am okay with the disconnection btw, as long as the re-login is totally idiot-proof, as my parents are just warming up to computers .

My second option is to use the auto-login extension with firefox. So i could have a lil autohotkey (or autoit ) script

Code:

---

run firefox.exe isp's-address.com
minimize firefox
wait 5 seconds
close firefox

---

How does the above sound?

Your best bet as nihil has said is to contact your ISP and inform them you will be switching to another company if they can't provide an easier solution.

If you are feeling more adventurous though... Capture the traffic as you POST the username and password info. Copy the http traffic from the post into a text file and then schedule netcat to run every 29 minutes or so using the text file as your input.

Given the string he provided as the example URL, it would be a GET not a POST. It SHOULD be relatively easy to download say 'wget' for Windows, write a quick batch file that made wget request the proper URL, then use the Windows scheduler (AT) to run the .bat file every 29 minutes or so...

A couple of things to be wary of: 1) It might violate your use policy that you agreed to when you subscribed to the ISP and 2) I hope you aren't charged for the time you are connected...

EDIT: Since you didn't specify, I'm assuming windows, which is actually a little trickier. IF that is not the case, let us know what OS your parents are using...

Yes, It would help to know what the OS is. I don't know about the ISP you use and their software, but your browser and/or Windows should give you the option to remember logins and passwords?

Sometimes this facility is also provided by your modem/router management software as well.

If your ISP has disconnected you, why would you want to minimize then close Firefox? Aren't they going to want the browser open to use the internet?

Ah! now i am getting some answers.

my parents will be using windows, though I have cygwin installed.

Firefox will be closed just to simplify things for my parents. Click on login to login. Click on browser to browse. besides if they want to use skype, and instead firefox opens, all hell breaks lose (from their point of view).

by capturing http traffic do you mean capturing http headers or using some sort of sniffer or something.
Anyways Using Proxomitron i get this on submitting my login info:

Code:

---

Posting 187 bytes...
admin_dosecure=
requesturi=
requestip=
ip=172.16.xx.xx
mac=xx.x.x.x.x.x.x.
nas=whatever
servertime=1172700717
startnet=1
username=actual-user-name-was-here
password=-the-real-pass
rememberme=on
login=Login

---

So i tried "nc.exe 203.3434.34.34 8886 < login.txt
Where login.txt contains the above text.. it didn't work
Anyways it check this thing also checks for time , so i don't think this would work even if i get it right. i will stick with the autohotkey method, crude but simple.

btw how would wget help here?

Try this: (I'm assuming that i misread your original post and that the forum actually requires a POST...if you look at the source of the page you are using to logon, look for <form action=BLAH> BLAH is the method to use...

I'm going to assume POST: (make sure to properly fill out the rest)

Make your file like follows:

Quote:

---

POST /portalcgi/userlogin.ssg?nas=xxxxxxx&ip=172.16.xxx.xxx&mac=00:xx.xx.x..x HTTP/1.1
Host: 203.12.x.x
Content-Length: X

admin_dosecure=
requesturi=
requestip=
ip=172.16.xx.xx
mac=xx.x.x.x.x.x.x.
nas=whatever
servertime=1172700717
startnet=1
username=actual-user-name-was-here
password=-the-real-pass
rememberme=on
login=Login

1) Make sure to replace the proper values
2) Make sure to end with two enters (blank lines)
3) Since I don't know the exact value of the variables, I can't compute the Content-Length and give it to you...it IS however required...Basically count each character starting with the first variable...not forgetting to count the end-of-line character. That integer will be the value of Content-Length (replace the X).

Unfortunately, the correct answer is to teach the parents to use the computer properly......like minimising applications for example.

My quick and nasty solution would be to set power saving to turn it off after 20 minutes of inactivity. That way they would be forced to reboot ;)

thanks for the explanation nebulus ( this may actually work!)
but its gmt+5:20 = 6:30 Am right now, so its about time i go to sleep ;)
i'll try this later

trust me i could become leet before my parents could learn how to send a mail.

Ok I calculated content-length , it didn't work . I tried a few variations as well. my guess it is because of
servertime=1172745975

nvmind it was fun playing with netcat.

As long as the time is a constant length (ie number of characters), that shouldn't matter...

Try this, copy the part where the variables are to the end of a file into a new file and use wc (word count, its a unix utility), and do this:

wc -m <file>

This will give you the correct content-length...
