Raspberry Pi is Working : Raspberry Pi is Working : Wahey !!!!!!!!!

dubbie

Eventually managed to connect to my old Raspberry Pi 1B. Not entirely sure which thing fixed the problem but I created a ssh file with no file extension, as a text file, as Shabaz described (who knew you could do such a thing? And why would you want to? I've never needed to do it before in 37 years of computing) which didn't resolve the problem by itself. But I then went to my local WiFi hub/router thingy and noticed that there was nothing listed as being plugged into the Ethernet. I then realised that perhaps plugging the Pi into my laptop was actually making a connection to my local network Ethernet. So I plugged the Ethernet cable directly into my WiFi hub and there is was, listed as raspberrypi. There were many shouts of great rejoicing at this point and I was tempted to stop on this great high.

 

It makes sense to plug directly into the hub when you think about it but when you don't know what you are doing it is not at all obvious.

 

It wasn't showing the IP address though so I tried pinging raspberrypi.local as suggested, nothing. So I thought I'll just ping raspberrypi as that is the name listed on the hub and there it was, now called raspberrypi.home with an IP address of 192.168.1.151. Marvellous. So I put this IP address into Putty and contact was made!

There was some message about the servers host key not being cached in the registry, no idea what that means, so I just went with Yes. Failed again. Great disappointment. Maybe it timed out, I'll give it another try. That worked without asking about server keys and whatever and I was able to login and get going.

Hooray, Hooray, Hooray. Who needs keyboards and displays, or HDMI cables! Whoppee !!!!!!!

 

I'm going to for a lie down now. All I have to do now is to figure out how to turn it all off. Maybe I'll just leave it al connected and logged in for the moment.

    Shabaz,

     

    Thanks for the encouragement. I could not have done this without all the advice and comments of the Element14 Community. It was a challenge trying to get all the steps sorted out without getting much feedback from the Pi as to whether what I was doing was working. The LEDs near  the power connector did flash a fair bit when power was applied which I took as an indication that the Pi was doing something, and when the Ethernet connector was plugged in the nearby LEDs did flash a lot, so I assuming something was happening.

     

    Thanks for all the links everyone, they have all been very good.

    Ralph,

     

    I must admit to just removing the power last night without shutting down properly. Hopefully all will still be well, but if it isn't then I will have learnt a lesson.  My next task now is to get an LED to flash using Python and then think about my possible Picasso Challenge idea, which hopefully will involve a mobile robot.

  • Congrats! Doing it without the HDMI display and mouse/keyboard is an advanced thing, since so much depends on what it's connected to, trusting that the boot is occurring without visually being able to see it, and so on.

    Now you've done it, you might never want to go back to using a separate display/keyboard again (unless you really need something with a connected display), since SSH from your normal PC is so much more convenient.

    Also, it's great to see that the original Pi still functions with the recent images.

     

    There's a bit of miscellaneous stuff here that might help, such as how to transfer files, etc., if you need to do that for any projects, plus some popular commands you can type in the command prompt (shell):

    Accessing and Controlling the Pi

    Working with the Pi: Getting Online, I/O and Command Lines

  • Welcome to Linux.

     

    You can shutdown the Pi by issuing the following while logged on to the Pi:

       sudo poweroff

     

     

    You'll have to unplug the power from the board once it is off.

  • Glad to hear everything is working.  Have fun with your Pi.

     

    Remember that before you power down your Pi that you want to halt the operating system. Or you could corrupt the SD card.

     

    Use "sudo shutdown -h now" at the command line (don't type in the "s). Your putty window will lose its connection (but not close).  You'll need to reconnect next time you power up.
