on the Qt/

[lucy24]

Does anyone know for sure what this is?

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko) Qt/4.8.2

It seems to be human, but with some iffinesses-- including but not limited to the fact that it came from a minor AWS range. Is it some kind of mobile?

Log search for the string "Qt/" turns up a lot of things with some kind of Safari at the end of the UA-- as you'd expect with "WebKit"-- but also a few ending in the same bare Qt/{various-numbers}. Most of them seem to be from AWS or server IPs, which does not inspire confidence. The one that prompted the question happened to be a redirected request, so I know it wasn't a one-time transmission error.

Not mobile, "Qt" is software for developers accessed by browser extension.
from qt.io:

• Qt Framework & Qt Development Tools
• Additional professional development features, tools & functionality
• Timely global support directly from the official Qt Support team
• You avoid legal risk and secure your intellectual property rights
• Close strategic relationship with The Qt Company with priority access to Qt R&D
• Your choice of term or perpetual commercial licensing

D'you think I should treat them as human? I had another look at raw logs, from a different angle, and found that most visits were fully humanoid, except for never requesting the favicon ... and the vast majority came in by the front page. That's simply not how people arrive at my site.

And then there was that odd string of <noscript> piwik requests-- three sites in three seconds, repeated a minute or so later, which passes credulity-- but the IP turned out to be my own host,* so I guess it's remotely possible they were doing something administrative.

Feh. If they want a hole poked, they can ask. And if they just want to confirm, for reasons of their own, that the site is up and running-- well, the 403 page plus supporting files will convey this information just as well.


* Detour to cross-check here. Not the same range that I posted about on an unrelated issue in a different thread.

There certainly may be more to this software than the user end, possiblly bot parsing.

Hopefully someone more familiar will come along or there might be more insight on the web site.
