Yep, it seems like a DDoS is underway. You report 28 000 but some 7 hours ago it peaked on 33 000.

The visitor statistics are normal, meaning these "visitors" may be bots as they typically don't execute Javascript.

Let them troll, our server can take the load. :cheers:

I don't think a DDoS would actually register visitors to the site. Those visitor numbers are determined by cookies and DDoS usually doesn't come through using a browsery type interface.

The site for me was down for about 5 minutes earlier, and I was wondering what it was

There are different ways of performing a DDoS.

It can be as simple as a wget instruction looping from a script to a specific URL as a distributed computing environment with thousands of different zombies targeting hundreds of pages and mimicking normal users.

On this case, I would imagine something more on the range of the wget category of attacks. Getting the page content but not executing the javascript portion since it is not viewed under a browser. I have no idea of what they are using. Almost two years ago we really had a series of attacks that made the site unusable for half a month.

Will see what can be done to counter-act this prank.

130 members, 25363 guests


25 000 guests is too much to be real.

If the forum has Ads and it's payed to the numbers of views, I wonder what G***** says about this.

Of course the 10 pages rule doesn't apply for guests because there are viewing one page and the attack is well timed and thought.


Should the forum be made members only?

It says nothing, the ads are only triggered by javascript which does not seem to be executed on this case. In either way, they are well used to handle these things from other sites across the web.


Should the forum be made members only?

No need, we proceed with business as usual. :cheers:

Heh. I didn't know that a DDoS would come across as visitors. That's interesting.

I did check yesterday that neither of the other two forums (that I bothered checking) on this IP are showing the same amount of users. It definately appeared to be directed to this forum for sure.

Seems more list a screen scrap of data than a DDOS. Typical DDOS attacks would not show up as visitors. The DDOS attack makes TCP connections to the server to flood resources, but doesn't really need to actually query pages. Check the logs and see how many other pages those 'visitors' hit.

Don't worry. We know well how to handle these matters and we are well prepared to face them.

In the past they caused havoc, right now their effects are barely noticeable enough to disrupt our services.

Yes what we are now experiencing must be a trick of the mind, let us fake that the forum is normally functional, that one page evey two doesn't time out and needs to be refreshed/reloaded and expecially let us fake that it is normal that to edit a post 10 minutes or more of repeated attempts are needed.

The ostrich has survived for a lot of time using a similar technique:
http://en.wikipedia.org/wiki/Ostrich
Of course at the time Pliny the Elder wrote his report, they did actually bury their head in the sand, the fact that nowadays they don't anymore, is that in the meantime they learned how futile it is. ;)

Hmm.. they probably picked TracePE because it was a juicy download of 300Mb.

Ninja pendisk also has amazing stats, over 20 000 downloads to a mere 14 000 page views.

It is such a good program that people don't even visit the download page and download it right away.. :lol:

I disabled anonymous login to prevent this leeching from continuing.

I browsed reboot.pro w/o login.

No "Download" tab / buttom / link visible (or I didn't see). But by clicking one of the "Latest Files" I came into the download area and could browse it.

Browse is ok, but e.g. to download winbuilder.exe there is no way.

Is that intended?

Maybe unregistered users get a captcha for download something ???

By registering, new users also receive the newsletter and that is important to promote the new activities going on at the forum.

So, I prefer to see them registered and raise awareness for the work that is being done around here.

Sorry for reviving an old thread, but curious to know whether the counters were resetted to zero after the rebuild?
