Hello there, and welcome to TechErudio.com! What does TechErudio mean? Well, it’s pretty simple… Tech is short for technology and Erudio is the latin word for education. Tech + Erudio = Technology Education!

The site’s focus is educating readers about computers & the internet, photography, audio/video and technology in general, through easy to follow articles and video tutorials. I’m just getting started, so be sure to come back often to learn more great stuff! If you like a post, be sure to pass it on and tell a friend 🙂 This is just a hobby for me so far, so I’ll try to be timely about responding to YouTube comments, but honestly, dealing with spam and hackers on this site is a huge problem, so comments here have been disabled. If you ever see any pop-ups or anything weird, please let me know in a YouTube comment. Thanks!

  1. HI I am following you on you tube but i am current stuck with ssh and vnc on my Imac to Pi.

    the error I am getting is as follows.

    null):~ babbar_sunil$ ping 192.168.0.8

    IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
    Someone could be eavesdropping on you right now (man-in-the-middle attack)!
    It is also possible that a host key has just been changed.
    The fingerprint for the RSA key sent by the remote host is
    9a:35:d9:e0:b1:c6:17:a0:54:1c:a5:e4:00:19:9d:92.
    Please contact your system administrator.
    Add correct host key in /Users/babbar_sunil/.ssh/known_hosts to get rid of this message.
    Offending RSA key in /Users/babbar_sunil/.ssh/known_hosts:5
    RSA host key for 192.168.0.8 has changed and you have requested strict checking.
    Host key verification failed.
    (null):~ babbar_sunil$

  2. You need to remove the line for 192.168.0.8 in your known_hosts file

    Open your terminal on your Mac and type: pico /Users/babbar_sunil/.ssh/known_hosts

    Go down to the line beginning with 192.168.0.8 and hit CTRL-K (That will delete/cut the line)

    Then CTRL-X to save and exit.

    Now try it again.
