Headless Kickstart board SSH address problem

Postby leon_heller » Wed May 18, 2016 10:21 am

I got one of the first Kickstart boards and have never been able to get it to do anything until today. Whatever I've tried, the single LED coming on is all that happens. I sat down yesterday determined to get it to do something. Using a different 2A PS and the 2016 headless distribution this morning I have just got the second LED to come on with the first blinking at 1 Hz. Presumably, it has now booted satisfactorily at last!

I'm using PuTTY under Win 7 x64 for SSH comms, but can't get it to work. The ID on the board and on the box is 04:4F:8B:00:04:3E, but when I type that into PuTTY as the host name it doesn't get recognised. Leaving out the colons gives the same result. I've never used SSH before.

What is the magic incantation that I type into PuTTY?

I've just seen that I need a crossover Ethernet cable. My local computer shop is adding one to their order and will have it in stock tomorrow.

Hi

What helped me best is the Suzanne Matthews tutorial on SSH - in the "How to" section iirc.
I made my own tutorial for Linux but it might help as I also use Putty - available under "parallella-examples/paralle2/doc", github or last 2016.3.1 headless Zynq 7020 image.

If you choose the static IP as I or Olaf did recently, it should work ; did not test the DHCP method.
Good luck :)

This ID is a MAC address (the world-unique address of that Ethernet interface), but since SSH uses the IP protocol, you need the IP address of the board.

If you connect the Parallella to your home router (assuming you can plug both your computer and the Parallella into it, or use WiFi on your computer), then you should be able to see the Parallella's IP address on the routers web interface.

Any Ethernet cable should work. Modern network interfaces are able to automatically detect the type of cable and switch the wires accordingly.

Thanks to both of you.

I connected the Parallella to the router using Ethernet. My laptop has a wi-fi connection to the router. I then opened the router as a web page and found the requisite IP address. Using that I was able to use PuTTY to establish an SSH connection, logged in and was into Ubuntu.

I've now got my Kickstarter board working, at last!

I did not use a static, I used the DHCP of my router
I went to the page of my router to see the IP address.

And as far as I have noticed, the IP address stays constant even when I put other SD cards in with different versions of the OS.
The only thing you must realize, a different SD card means a different encryption key sou you must remove the one that is associated with that IP address first.
In my case Linux (Mint) literally showed me to command to execute to unregister. Just copy and paste.

I run Linux in a VWare on, Windows 10.
Something you must be aware of is that it is probably going to connect in a NAT.
With NAT your computer will have a different IP address range than your modem and maybe out of contact from you Parallella board.

You have to modify the VM machine to connect in "Bridged mode". Then you VM Linux gets the same IP address range as you Windows, router and parallella board.
