  1. I find value in going back to basics like this. Almost every time I watch one of these I have a "oh I've been doing it wrong" or "thats what that command does" type moment. Granted I am no hacker…I just like the challenge of making linux work.

  2. It's worth noting that traceroute results should be taken with at least a grain of salt. Many things can cause intermediate replies to be lost, leading to line after line of asterisks. Also, "traceroute" (Unix/Linux) and "tracert" (Windows) probe the network differently and can return different results. Finally, because of QoS and other factors, it's possible that the route you get back is NOT the route your traffic actually takes. I've even seen cases where the return packets take a completely different route back.

    That said, thanks!

  3. In high school the website blocking system was basically a list of domains that the browser would block. I found that in DOS I could run Ping to get the IP address and so I started selling my 'workaround' for 5 dollars a site. Ended up selling loads of workarounds for Also, ping is really nice to just keep running on the side in cases where, let's say you're trying to work some ninja magic to bust your way into a wireless access point. Never used any of these tools for something actually constructive though. Lol.

  4. Comments show that there exist in Linux, mainly arrogant elitists, who love being in the 2% minority.

    The "ping" command works in Windows-10. Open the Windows terminal. ("Win-R", then "cmd").
    My method used: Cygwin 2.8.0-x86_64.exe … following the installation instructions.

    To use the other Linux commands in windows, I googled: "windows linux bash"
    This led to:

  5. Here is one that some of the readers and watchers might be interested in. If you upgrade Ubuntu from 16.04 to 16.10, you might loose your network connection. Happened to me. They are saying to run this command. touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

    It does work.

  6. Why don't you put the word "BASIC" at the beginning of the title. Ping, really??? We are not 5. I know you have to start somewhere but really. You spent a third of the show on Ping. Your good but you could have done better.

  7. 8:41 We should stop using ifconfig, the ip command is recommended, ip a s, for same results. Things get deprecated, for instalce we should also stop using uname -r, and use hostnamectl instead.

  8. Glad to see this series is back. I have to agree with other comments that these commands seemed much closer to the beginner side of things than 201 would suggest. But still looking forward to future episodes.
