LINUX INNARDS:

Travel Networking

Joe

First get a travel router unless you want to set up one of your laptops as a hotspot

I suggest the GL.iNet GL-AR300M if you want a robust machine.

Comes stock with openwrt and 128mb nand flash which allows you to install applications.
It does not have 5ghz which is a con
Installed easytether and nano using opkg

Otherwise if you want a simple setup I suggest the TP-Link MR3040
Setting up a netbook as router with dnsmasq is not too difficult and while it adds to complexity in some ways it removes some in others

If not one of the routers that I suggested then try something that is 5v.  I know a couple of podcasters that stand by the HooToo TripMate Titan.

The 5v travel routers are nice because you can use any cell phone charger or a port on your laptop.  Any USB port.
Comparatively the 12v or higher voltage routers have more functionality but are more limited in where you can hook them up

 The point of getting a setup like this is that you can set the wifi to be the same name and password as the one from home

This means that everyone’s devices will almost automatically connect.
Because it is a different device you may have to tell your devices to connect to it the first time but the password will already be stored
This means that you will be able to take it to the grandparents house and just hook up the ethernet cable and everyone will be ready to go

This device can also be useful while traveling down the road.

You can set up a local area network in your vehicle and have one of your devices act like a server and provide media to all the other devices
Texas is a big place that takes a long time to drive across with many open spaces with very little cell connectivity
A simple low power device like a netbook or a pi which keeps things at five volts and a plex server can provide endless entertainment for the kids and passenger.
The server is why you need something that can set static IP addresses

Usually your phone is more than good enough for your listening needs but if phone memory is a premium it may also be nice to have a music server setup.
As for hotels the setup is mostly the same as for at the grandparents house with some addendums

Many hotels limit the number of devices that can be connected at one time.  The router is a good way around that
The easiest way to get up and running is to allow your phone to connect to the wifi and then use easytether to provide that connection to the router

This however can be limiting to speeds
You will also need to use the phones browser to get past whatever login screen the hotel has

 The next way to do it is a bit more complicated

Hook the router directly into the ethernet(if you are lucky)
Then you will need to connect your laptop to the router wifi and use ssh -l to forward port 80 and then go through the login screen.  All your other devices should then work fine
Also recommend using a vpn which I will cover soon

VPN

A VPN is a great tool while traveling
It has 2 main uses.

One is security
The other is giving you access to your entire home network without opening more than one hole
We have done other shows where we talked about how to set one up and why your public internet connections should always be encrypted.

Easytether

Pretty easy to use.  Need the android app and the server/drivers.
You need to go out to the easytether drivers website and grab the proper one based on the processor or operating system that you have
For the AR300M I needed the ar7xx drivers which I had to extract from the zip and push to the devices tmp
Then I used opkg to install and had to use the command easytether-usb to get it listening
I also needed to make that command run at startup which is a matter of adding it to the rc

Make sure the first line of your script reads:

#!/bin/sh /etc/rc.common
Copy your script to the /etc/init.d/ directory
Make sure the execute bit is on

chmod +x /etc/init.d/your script
Enable your script

/etc/init.d/your script enable

Your script should now have a symlink in /etc/rc.d/

ls -lh /etc/rc.d | grep your script
Confirm your init script is enabled:asy

/etc/init.d/your script enabled && echo on

If this command returns on, then you’re all set. If this command doesn’t return anything, then your script isn’t enabled. Here’s an example of a script that’s enabled:

root@OpenWrt:~# /etc/init.d/system enabled && echo on on
https://stackoverflow.com/questions/33340659/how-to-auto-start-an-application-in-openwrt

Also needed to add the interface for the network

cat  EOF /etc/config/network

config interface 'wan'

option ifname 'tap-easytether'

option proto 'dhcp'

EOF

On the phone you need to turn on developer mode and usb debugging
With a laptop running Ubuntu it is a matter of installing the drivers and then turning off your other interfaces before connecting your phone. You also will need the proper drivers for your device as well as adb.
Found out something very disappointing.  My cell company now detects easytether usage and throttles like any other tethering.  Yes I am still looking for a workaround.

Most of the apps I use are directly on my phone. Bring a pair of headphones with a mic, and I’m golden. Most of the time, I try to disconnect, though. Mental fortitude is at a premium!
If I need to access things at home from away, I have my VPN certs on both my phone and my laptop. Phone when I don’t have wifi, and laptop for when I do.
The Nextcloud desktop app is where I do all of my work like news articles, or accessing docs or pictures.
I can get to my VSphere host, my NAS and other little devices via VPN as well.
If I’m in a no service area altogether, Plex sync is fantastic. Fill up your device before you go, and you’ve got hours of watching/listening.

Have a plan for NO connectivity

Local media on external HDD, for VAC
Bring portable set-top box or HDMI capable laptop, HDMI cable, to connect to a TV in hotel etc
Pro Tip: Bring a Raspberry Pi and set it up with both Kodi and Retropie (Batocera has BOTH – also there is a Kodi plugin for Retropie)
Scope nearby places with wifi, in case network is not good

Volla Phone Kickstarter – 300 Euro privacy phone, only needs $385k to get going, kickstarter ends SOON Dec 15, lots of cool things about this one. Runs AOSP with no Google apps but almost all Android apps, or can run with Ubuntu Touch. No US phone yet, Europe only.
Synaptic is 18 years old (unmaintained for the past 2 years)
MS Users Now can use Puppy with just a few mouse clicks (LICK Installer, no CD/DVD or USB stick needed) LICK can be used with any distro and is MIT licensed, but uses Puppy to demonstrate the concept.
