TL;DR

Leave /etc/network/interfaces as it is

Add to /etc/dhcpcd.conf

interface usb0
static ip_address=192.168.42.42/24
static routers=192.168.42.129
static domain_name_servers=192.168.42.129

Restart the Dhcpcd service

$ sudo systemctl restart dhcpcd

I *think* my issue is that my home network is a 10.0 and not a 192.168 and I’ve not quite hit the correct combination yet.

If I set up like this and other posts state then I see the usb0 interface and it has the 192.168.42.42 address but the tablet can never connect there – either ‘no route to host’ or the connection just times out.

If I ssh into the pi on it’s assigned address then I can ping the 192.168.42.42 address and I get a response.

I’ve tried changing the 192.168 to 10.0 in all the examples but so far no joy.

I know just enough to be dangerous but if anyone can give me a pointer in this case I’d greatly appreciate it.

So I have done all steps from this blog , but after the reboot I only see “lo” in the ifconfig (before the Reboot everything was fine, I also have seen USB0) and my wireless interface is gone too.

How to fix the usb0 not showing up in ifconfig.

Make sure to do each step.

– Connect data cable
– Physically go and turn on usb tethering again. Mine shut off every time I plugged in the usb
– Run ifconfig with tether turned on. You will see usb0 but it will probably have a different address.
– Change the address in the VNC app to what is actually shown on the ifconfig print out
* mine changed from 192.168.42.42 to 192.168.42.214. I left it at port 1, so 192.168.42.214 but they key here is that it’s not actually on 42.42 but something else.

That should fix it.

FYI I am on a raspberry pi 3 late 2017 and android 6.0 not that it matters.

Here is a picture of it working.

Just a little remark if you have a PI 3 B you need to leave /etc/network/interfaces allone
when you need a static IP . But instead go and add e.g.
interface eth0
static ip_address = 192.168.xxx.xxx/24
to the /etc/dhcpcd.conf file ..

I hope this helps

Now I tried to create 2 virtual usb with following static ips
192.168.42.11
and
192.168.43.11

and assume one of them will be accessible , but now mobile is giving me a dynamic ip with same config as yours. Any idea how to handle this. I am basically running an http app on rpi and check in app which of the ip is up 42.11 or 43.11 via simple http get and launch whichever comes up. If I do networking reboot once tethering is on, this works.
