Okay, for some reason once I was in, I went straight to the back. I should have played closer to the fence for a while.

Anyway, I'm at 21 now.

No, you should do this with the first version; the second one could be used, but requires more work to make it go, as it doesn't deal well with the response code the server gives once you start digging.


the newer version in Python 2.4+ doesn't have "the response code" problem mentioned here.


For what it's worth, I went through the pain of learning the "newer brother", and while I agree it's more complex than necessary, there is a module out there (not in the stdlib, but you'll find it if you google for the specific code you want to deal with). I did it with python 2.2, so it's not *necessary* to upgrade to 2.4.

On to 21!

Thanks to some prodding from Uncle Timmy I made it to level 21; it turns out I was fooled by thinking I had looked at the back of the premises already, by a faulty office proxy server (transparent and hidden to me until today).

See you at the next topic!

Congratulations, Martijn! I'm heartened to hear that even the fellow who implemented this part of Zope had trouble doing obvious things with it :wink:

:cry: That sucks. Is it possible to explain the symptom here without giving away the store?

See you at the next topic!


From some brief thrashing last night, level 21 seems deliciously obscure compared to this one :wink:

It was just a crappy (Microsoft ISA) firewall that also transparently would turn any port 80 communication into a proxy request, and (spoiler removed)

So, I got some clues about getting inside at home, then tried the backdoor at the ofice only to be rebutted by apperent errors; but that was just the proxy server not dealing well with (spoiler removed).

I can't figure out the password for the package.

You missed something from the big picture.

Did you check out the all of the back and the front of the premises? Did you check for url-hints based on your findings? Did you get called anything?

so I thought I was done with this level, but now I'm stuck with a file with an md5sum of
cead24b279a5ca5af49ffe671bd3406d

and I have no idea what to do :-(

Does that md5sum match up to a file I should have, or did I go wrong somewhere?

Yes, that's a file you should have. But don't you also have a file with md5sum 6c263598a8c6c4dd4a51e0f592540593? It's hard to imagine how could have gotten cead24b279a5ca5af49ffe671bd3406d without getting 6c263598a8c6c4dd4a51e0f592540593 first. If you have the latter, examine it more carefully.

I've followed the chain, i've been told i'm inside now. i printed out all the info i got along the way. I've played with URL's based on that info and received only an affirmation that I am what I've been called.

I haven't a clue where to go now. Did I miss something?

I think just about everyone stalls at this point, so you're only missing the joy of being stuck here as long as everyone else was :wink:. There are a ton of clues here about what to do next already, so go back and read earlier msgs for this level.

Argh! I've read through all the hints about 4 times now. They all seem to be stuck *getting* to this point, not getting past it.

I'm using the earlier version of the library with Python 2.3.5, but I've also poked around with curl. I can't see what I'm missing.

I'm getting a headache from banging my forehead on this wall...

Oh well.

You're more likely getting a headache from banging your head on the fence -- since you can't stop your head from banging, move away from the fence (and reread the messages again to find other clues of that kind :wink:).

Note that Martijn had some obscure problem with a proxy at his office that prevented him from making progress here. I'm not sure what that was about. Maybe a PM to him could clarify whether you're having the same kind of problem.

But before that, have you made use of the "sequency" number? If that doesn't ring a bell, you definitely need to read the hints again.

Oh yea... I have 6c263598a8c6c4dd4a51e0f592540593 and a52ee73318b8943c829362b53700ea31 as well.

Is there something else hidden in 6c263598a8c6c4dd4a51e0f592540593 or do I just not get the hint inside a52ee73318b8943c829362b53700ea31?
