3:03 bind
6:13 what is an interface
6:18 meeting between two thing, aka. *network adapter*
9:58 assume another type of interface
10:22 this interface doesn't have to interface the outside world
10:37 e.g. backed by another green box (a user-space program)
11:24
11:30 this interface named to *tun0* - 11:35 a virtual interface, which is not backed by actual hardware, 11:39 but *backed by a user-space process*
11:42 a *tunnel*
12:41 what is a *tun* used for - 12:44 commonly originally used for *VPN*
14:12 NAT - network address translation
19:00 e1000
19:34 *ethernet is just the local network*
20:43 br0 - Linux *bridge*
28:24 interface: ovs0
Anyone who is saying that they don't understand or finds this video confusing obviously don't really appreciate the value this video brings. After they get some experience, they will find this video golden and wished they truely took the time to understand what this man is explaining. Thank you for this great content!
If you know then why would you even want to watch the video lol
Dude this actually explained sooooooo much about networking for me.
Thanks ❤
Thanks for the video! best explanation in youtube
Thank you very much for your videos. They helped me a lot in my K8s journey.
Great video, very well explained.
Great video! Helped me a lot!
Great video, very well explained.
thanks sir
Thank you. I am a Proxmox user and this helps he understand more of what is going on "under the hood"
This is excellent.
Great video. Quite in depth and really easy to comprehend. You could add some info about virtual dot1q subinterfaces unless it's in part 2. Thank you very much.
Thank you! And yes I do cover vLAN interfaces in Part 2 :)
Thank you, the fact that the bridge and the host interface have the same name was confusing for me too, and I spent hours looking for a video explaining this until I stumbled upon your video and I am glad I am not the only one that found this confusing....I understood the concept but I had always a doubt in my mind that I couldn't dismiss until now.
some concepts needs to be said explicitly, and you did that thank you.
@@jayjaymcfly7475 I advise you to study for Cisco certification (CCNA: just the course without trying to pass the exam), practice in "Cisco packet tracer" and "GNS3", its the best introduction to networking. Next try to understand Virtualization technologies: Hypervisors and Containers, virtual networks and interfaces.
@@jayjaymcfly7475 you can find free ones on RUclips, they're good.
@@jayjaymcfly7475 I happy to help, you didn't bother me at all.
Thank you so much
deadbeef and coffee awesome MAC addresses, Sir.
Useful videos. Are slides available anywhere? Any references as to books/docs to catch up on latest approaches and to get more details/perspectives on software networking?
at 25:50 why no packet can go to internet from bridge, eth0 can do a two communication right so if packed sends data to eth0 , eth0 can then send the packets to internet.
currently stuck with static route to access the networkbridge from outsite brought me here
eth0 can also be assigned an ip address so why is bridge being assigned an IP address, will etho0 wont talk to internet ??
I didn't get it .. its over convoluted and explanation could be more easier and simpler....that's my thoughts
Brctl is getting deprecated. Use IP command
brctl
not clear explanation
5 Errors in the first 4 minutes. I have to stop listening.
What are the errors
