I am currently using AWStats to analyze the apache logs for a server that redirects links, etc from iOS apps to the app store (so we can track clickthrough). In AWStats, however, all of this traffic is grouped into 'Mac OS X' in the Operating Systems category. This obviously isn't very helpful for us. What we really want is not only detection of iPhone vs. iPod Touch vs. iPad, but also iOS version numbers, hardware generational differences, etc.

I don't think generational differences (iPhone 3G vs. iPhone 4, for example) can be easily retrieved through http logs, but I know that iOS versions are right in the user agent string.

None of my attempts to get AWStats to recognize iOS have worked at all, though. I moved the line that's supposed to do the trick up above Mac OS X, to no avail. Has anyone managed to do this, in AWStats or otherwise? I'd be fine moving to a different system, if that's what it takes.

For the record, browser detection works fine, it can easily distinguish between mozilla, safari, iPhone safari, and iPad safari.

I don't know that much about VPN, so it could be that this is utterly impossible. Here's hoping, though.

I would like to forward a port from my router to a machine connected to the network via VPN. That way, I could run a simple server on my laptop, and it would continue to work at the same address no matter where I am. The trick is that I don't want people connecting to the server to have to join the VPN. It should be completely transparent to the end-user.

If it's not possible with VPN, is there some other technology that would make this possible? Basically just forwarding a port to a remote machine, one without a static IP.

I have a user on a Ubuntu system of mine who needs sudo access, but I don't trust him as much as I'd like to be able to. Is there a way to log all of his sudo activity, and email it to me at the end of the day?
