/prog/ - Scaning web

Hey /prog wassup?
I've got an issue here.
I know this web which saves jpg's in a kind of "hash code".
Like this:
www.web.com/4h5ah13qod4j3sg.jpg (15 digits)
I was wondering, is there a way to scan through it to know in which adresses I will find jpgs? I can do it manually.. but tried about 20 randomly and couldn't find one, so I guess it has a low charge constant..
I know some python but have no idea on how to do this. Or maybe i could look for some software to do it for me.
Oh! and i'm on linux so i have all its tools..

Just loop through the 2e23 or so hash values and see if they return an http 200 or 404, easy peasy.

I wish you the lowest latency in your quest.

thank you! I'm using httplib to see what the return value is and urllib to download the jpg. I had some trouble cause i didn't pay attention to the fact that https webs (as mine..) use a diferent connection (HTTPSConection instead of HTTPConection). Noob mistake i guess but drove me crazy for a while.
And latency is pretty shitty, but i'll have to stand it.
Thank you again bros!

Enjoy your year(s) of querying the entire search space. Assuming it isn't growing at the same time too, that is

Too bad that's only a subset of the tools you would have on Windows.

Too bad everyone and their dog would see what I'm doing on my computer on Windows.

Looks like at least 36^15 search space.

Even if you had a botnet that could do 1000 tries a second (and the servers could serve that rate) it would take over 7 trillion years to try them all.

After 12GB of downloads, from probably-safe-freeware.net, sure.
