The download sub-link given by a Google search for LinuxCNC is entitled Cialis for sale com. Clicking on the link provides a different download page than accessing the down load page by opening the home website page and choosing the download link at top. Although this page is dated 19 August 2012 it appears to be an older version than the page dated 3 May 2012 accessed via home>download. This happens on different computers, different browsers and different networks suggesting that it is not a local computer problem. Can this be fixed?

I think we hoped that it had been fixed.

The problem was a hack to the website that supplied different content to the Google Bot than to a normal user. You can see the effect by changing the "User Agent" string of your web browser.

What you are seeing now might be a stale Google cache. Or we might have been hacked again. :angry:

I do think its just a stale google cache. Looking at the download page with three different search engine user agents yields nothing funny.

Did you try GoogleBot as the User Agent?
www.useragentstring.com/pages/Googlebot/

(I am not sure how to do that with this machine)

Thanks for the replies. I assume that the cache must be on a local (Australian) based server if you do not have this problem in the US. There problem has been there for more than a month. Is it possible to force a flush of the caches?

Problem still there. See previous post. Is it possible to force a flush of the caches? This problem does not exactly inspire confidence in LinuxCNC!

How do you see this? as far as I know this was fixed at the beginning of the
year and google caches seem to have purged the old info. That is if I do a
google search for "linuxcnc" I dont see anything funny anymore.
What is your search term?

Also not sure what this has to do with confidence in LinuxCNC
(confidence in joomla or humanity maybe...)

As a side note cnczone.com is now marked as a dangerous site by google
so few sites are really immune from occasional hacks

Thanks for the quick reply. The problem is exactly as described in my first post. If I do a google search on linuxcnc one of the sublinks listed under the main heading comes up with "cialis for sale". This happens on iPhone, iPad home and work PCs all with different servers.

I have written an article praising the use of linuxcnc to control the leadscrew on a lathe. This will be published soon in a hobby magazine. It is somewhat embarrassing to direct hobby machinists to a site that has been hacked. Hence my desire to fix it if I can.

I take your point about hacking but I have not seen other sites that exhibit this sort of problem.
