Sharing your computer's Wifi connection with Parallella

Postby aolofsson » Thu Mar 20, 2014 12:38 am

This is a nice trick that I learned from some clever folks at the Eclipsecon hackathon. Turns out that it's really easy to share your internet connection with the Parallella using Ubuntu without needing to use a router. Here's what you need to do:

On laptop:
-Run a recent Ubuntu (I run 13.10)
-In the network-manager, edit connections and create a connection called "shared wifi connection"
-Edit that connection and in the ipv4 tab, select "shared to other computers".
-Connect an ethernet cable from your computer to the Parallella
-After being connected to the internet using wifi, clock on your new "shared wifi connection"

There are lots of posts explaining this further, here is one:
http://askubuntu.com/questions/359856/u ... h-ethernet
http://askubuntu.com/questions/359856/s ... h-ethernet

On Parallella:
1.) Connect the parallella with serial cable to your computer (or use a keyboard/mouse/hdmi screen to interact directly).

2.) Check that network interface definitions looks like the following.

/etc/network/interfaces should have the following
auto eth0
iface eth0 inet dhcp

You may also need to remove the following file and reboot:
/etc/udev/rules.d/70-persistent-net.rules

3.) At terminal, reset the interface to allow laptop to assign IP address to the board:

sudo ifdown eth0
sudo ifup eth0

4.) Verify IP address using ifconfig/ping internet.

This kind of thing has been in Windows as Internet Connection Sharing since at least Win2k.

Edit: Okay, yeah, late to the game.

I was surprised because it's extremely easy. :)

With Headless Parallella
Laptop:
-Running on Linux Mint 17.1 64-bit
-network-manager same as Ubuntu ( Steps 1.- 5. http://askubuntu.com/questions/359856/u ... h-ethernet)
-for finding IP addresses Installed ipscan ( http://www.upubuntu.com/2013/01/install ... pa-in.html)


Parallella desktop board :
-Connecting:

sudo ssh -XC parallella@IP( e.g.192.168.0.15)

-Running on Ubuntu 14.04 Parallella ( Zynq7010) headless image ( Jan 30th 2015 release, 515MB)

rm /etc/udev/rules.d/74-persistent-net.rules ( removing.. in my case the number is 74 not 70, don't know if it helped or not)

-tried:

sudo ifdown eth0

-Installing network manager ( https://help.ubuntu.com/community/NetworkManager)

sudo start nm-connection-editor

-Then ( Steps from 6. http://askubuntu.com/questions/359856/u ... h-ethernet)
-All works well

Hi everyone, I use your information to share internet with a static IP:

http://dennis.cr.rs/manuals/parallella_board/02_Tips/03_set_ip_for_the_SSH_connection_directly_by_ethernet.html

On Parallella STEP 2, only set:
Code: Select all
auto eth0
iface eth0 inet static
address 10.42.0.50
netmask 255.255.255.0
gateway 10.42.0.1
