@mitu: I suspect that you're right, it's some kind of bot filtering, but I'd go a bit father. My browser was left open for a few days, so I don't think it's just when you open the tabs. Since some pages, especially forum pages, phone home to check on updates, I think the site is aware of the multiple connections.

Thanks!

@Efriim Then the problem is the Samba share and not the Pi. Restart Samba after you the USB is mounted and then re-try to copy the file to the share.

You can always use your phone too. Samsung makes docking stations for their phones. I've used mine quite a bit while traveling. It provides HDMI output and a USB hub so you can plug in controllers.
