The purpose of the remark was get any concrete information on the
kinds of attack you were experiencing. If those are the same that
everyone on the internet is getting then it is hardly a sign of
you being under attack specifically after having accessed your
own hidden service.

Did you run the server before (I suppose not) and have the firewall
rules before so you could cross-check the attacks after the hidden
service with the time before?

I just operate a few http servers that have practically no regular
traffic, so my httpd logs are a pure trace of the vulnerabilities
that linger in diverse popular web applications.
Likewise I see the constant influx of windows RPC/messages/RDP stuff
in my firewall logs; and I wonder whether you actually know what
life on the internet is, or whether you simply installed the web
server & hidden service, saw all the shit hitting the server and
went 'omg, tor is obviously borken'.

So, what *are* the details of the traffic, especially in comparison to
the usual background, that can even indicate that there was a specific
attach on your server at that time.
Or, for instance, what are the signs I should be looking for in my
firewall/httpd logs to see whether there was a similar attack on
my systems after I started my hidden services.

Yeah, sure. I can research how you were specifically attacked. Care
to give some google keywords for that?

So what? The question is not whether someone is doing that, the
question is what makes you think you're getting these attacks
a) in relation to your hidden service and b) they are happening
only to you.

Yeah, sure. I get the same of every http server I have in the open
internet. Someone is always sweeping the internet for vulnerable
systems; the vulnerabilities change, the sweeping doesn't.
Nothing to see here, please move along and come up with something else.
Besides, the /{Tor hidden service ID}/nonexistentfile.php is
/a1b2c3d4e5f6g7h8i9/nonexistentfile.php, right?

Yes, they are.

Those don't attack the web server per se but some types of blog/forum
software. That's nothing you need a hidden service to be attacked with.
