Watching this episode, I realised early on that I already know most of what Scott is talking about. I still watched the entire episode, because I enjoy Scotts teachings. He is the school teacher I wish I had. If I ever have kids, I will put them in front of Scotts channel and watch it with them. I hope you reach 100k soon Scott, you deserve that snack!
I have worked in IT for more than 20 years and computers have been a part of my life for more than 30, yet from each episode of this series I learn a lot, I learn to rephrase my knowledge, to give it a new perspective, to simplify. Thanks Scott!
Scott - great analogy of the local IP reference to the 555 phone concept. Again another amazing video. You really fill in a great deal of small gaps that are I think we all have missed. If I could give an analogy, if we all had a series of incomplete puzzles all placed throughout our homes, you help fill in those missing pieces to really provide greater visibility. Thank you!
going to school right now and this is precisely what they didn't teach us and what I missed. had to laugh when you mentioned wireshark in the beginning, because it's also exactly what we're doing in class right now... thank you so much!
I've been wifi only for the last 3 years. Using 3 Eero mesh network devices. The first one plugged into my "modem" (Surfboard Cable Modem) takes on the Router role. Dual internal networks - main and guest are provided. Not a single hiccup as long as the cable is working. Also running the entertainment system via wifi as well as 4 computers, 3 or more mobile devices (phones/tablets). Even had solid connection 100+ feet into the backyard. Would highly recommend Eero.
Love the videos, so crystal clear with explanations and everything set out so well. By far the best I’ve seen to date. Keep up the excellent work Scott
Great presentation. It's a reminder of how much the temporary kludges of my initial home networking design have become givens. At some point, it would be useful to explain how simple the underlying concepts are with everything being turned into simple packets. Removing the mystery is a step towards understanding.
Thank you, Would love to see more videos about networking. really helpful especially the last part you mentioned about blocking certain content with DNS.
Thank you so much. I learned how to code since a teenager. I knew how to code, i.e. like do coding puzzles. However I never now how the internet worked. I was asked in a job interview "So what happens when you type a website in your browser and hit enter" I was like "Uhhh.... I don't know....". (I didn't get the job). Finally in my 30s I finally know what a CDN is. The acronym always sounded so intimidating and complex I didn't think I'd ever "get it".
Ey scott I'm passing here just to write one thing. Your content is pure gold. You oficially fucking rock. You deserve the best. IM LOVING YOUR AMAZING DIDACTIC
Hi Scott, can you follow up on that lesson and teach how to manage multiple wlan routers / repeaters best practice wise. Same ssid's? What are the cons and pro's and so forth.. thank you so much!
I so appreciate your series of videos. I am not what you would call a professional tech guy, more like a 50 year old child trying to discover the world around him. There are a lot of dangers out there in the world and everyone needs a parent to explain things. This video is full of information that I may already be aware of but needed to be put together in a way that I can understand, learn and experiment with. Thank you again for your work to help make the world of tech easier to understand. :-)
This was fantastic! Thanks! Maybe I misheard you, but to my knowledge many linux distros deprecated nettools and use ip instead of ipconfig or ifconfig. Those should still work on BSDs and MacOS. Thanks again!
Cool. You touched on a few security aspects there. A session on home internet security for the novice could be valuable. Especially what to look out for use on online banking, suspicious phishing scams and possibly where, what and how to use Two Factor Authentication.
I think if you build some kind of marketable product that is PnP to block adds...that would really sell ;) Enjoying your series very much! Keep up the amazing work
Very interesting tutorial. But it still leaves me with a lot of questions. E.g. Fiber -> converter box -> coax -> Modem/router box -> router -> local network. I heard that the modem/router box provided by the ISP needs to be set to Bridge mode to enable my own router to connect. That way the "public" PW on the ISP supplied box is no longer able to access my LAN because my router is protecting it with my own PW. However, what needs to be the setting for my router? Also Bridge mode or just regular router mode? I.e. coax -> Bridge -> router -> LAN ?
Awesome Scott! This is a really good series. Wish you would pickup where you left of and talk a bit about subnet/mask etc., even though that's probably not something the average user is ever going to touch. Also, perhaps file/printer sharing would be a good topic as well. I just recently reinstalled windows and had to reconnect another computer and it didn't show up in the network, even though it was suppose to broadcast its name etc. and previously showed up before reinstall. I had to put in the computer name in Explorer manually (\\MYCOMPUTER) to find it and then log in to it using the right credentials. Seems like features like these are really overlooked by the Windows development team. It feels dated, and thus isn't as smooth as it should be.
I heard WAN in many other videos but never i understood them till i find you here today and watched your vid, I will like it and sub here, great teacher. I want to get started in to hacking so i need pi, like how you have six pi's, i wonder what you use them for, i also would like to set u a small network at my home using pi, switch and router, just want to have the great experience. Thank you again! I JUST UNDERSTOOD THE DIFF BETWEEN WAN AND LAN!!!!!
Good explanation. Some I knew and some I learned. Then I have a problem that my 3 computers will not talk to each other. If I try to read #2 from #1, I get a box to put Windows Credentials in. One work around is to put files in my OneDrive, go to other computer & get file from OneDrive.
Awesome series Scott! I use the same Linksys router with OpenWRT and like how extremely customizable it is. But I'm looking for a replacement. The new hype seem to be unifi/Ubiquity. I hope you do a more advanced networking demo similar to this. With your Ubiquity setup if possible. I have seen your hardware installation demo. If you can, show the software side with technical explanations like this video.
The new hotness for wifi is Ubiquiti/Unifi but the new hotness for routers is pfSense. If you like how customizable OpenWRT is, pfSense is the way to go. Ubiquiti routers will disappoint you.
Great videos and great channel! Congratz for having 100k follower now, hope you received some cookies. :-) What broadcasting software do you use for recording your videos? I am particularly interested in the arrows you seem to be drawing while recording. Thanks and sorry if someone has already asked you this question here.
I've gotten so much from @Scott Hanselman over the years, some unintentional like the diagrams app used in this video :-) . I've been learning Docker in WSL and would LOVE a video about Networking and additoinal complexities when using docker in WSL and viewing apps in a pc browser (since technically WSL is the host?).
Around the 19 minute mark you were using the "server" command a lot. I hadn't seen this before, and tried it on my Windows 10 machine in PowerShell and it can't find a server.exe. Is that a special alias you've setup? Or maybe a 3rd party app that you've added to your PATH?
Hello Sir Can I opt for cloud computing? as I have completed my bachelors in software engineering . Secondly, is masters in cloud computing worth doing ? Or yah sit for certs Thanks
The subnet mask masks the part of the IP Address that is your "network part" . So if your ip address is 192.168.1.200 and your subnet mask is 255.255.255.0 it means that 192.168.1. ist the network part and the 200 is your host part. It means in this network you can have hosts (computers) from 192.168.1.1 to 192.168.1.254 (0 is the network address and 255 is the broadcast address) If you would have a subnet mask of 255.255.0.0 you would have hosts from 192.168.0.1 to 192.168.255.254. It is a little bit more complicated that I can explain here. if you need more explanation just write here ;)
