I want to develop my Pi project at various coffee shops around town. Given a laptop and headless Pi, how can I get networking setup? I'm assuming I need to connect the Pi to the coffee shop network, but how do I do that without a monitor connected to the Pi?
I have a couple of ideas, including: - modifying a noobs image on the spot on the laptop (but I'm not sure what will happen when the network asks the Pi to "accept" their terms and conditions) - use Bluetooth to connect to the Pi and set up the network settings through that
How have others solved this? Any ideas are most appreciated!
Are you trying to use your Pi as if you are a customer who comes into
the shop and want to use their "Free" WiFi whilst you drink your coffee
as someone else with (only) a laptop or smart-phone or tablet might do?
In the same way as some authors write whole books in Coffee Shops
there are Software developers who work the same way - and if you are
working with a Pi you may even get an audience who wonder what that
little box with the lights on it is for...
Plugging the Wifi Dongle of the Pi into the laptop (disabling any other built-in to the PC) temporarily and logging into the Wifi (and accepting the Sign-in Web-page that comes up in the PC's browser) will teach their system the dongle's MAC address, if you then deactivate the dongle (probably via a PC system tray icon) you should then be able to un-plug it and move it to the Pi and start that up. Some Free Wifi places like that allow more than one device to be associated with your free account, and if you are lucky they may allow more than one of them to be active at the same time in the same place. However you will probably want to have a VPN set up between your devices as such Wifi systems are not considered "secure" - e.g. Windows Firewall has special setting for "Public" Wifi setups so that things that you might share with other hosts on your home LAN are locked down on a public one.
Whether you will get twice as many adverts sent to you via EMail as the price of this remains unclear - there is no such thing as a Free Lunch (and Free WiFi may have its costs as well!)
EDIT: Silly me, forgot that properly set-up with the right keys shared between hosts SSH will provide a secure link between your Pi and Laptop. Also you will probably need to do the Windows equivalent to the Linux
The coffee shop has a DHCP server such as a ADSL router. Just set up the Raspi as described and connect it the Ethernet network.
The network is normally Windows network and only the
To do this on Debian you can install samba on the Raspi
This also works for BeagleboneBlack and as far as I can remember also with Ubuntu.
