I have used named pipes once professionally, and it was extremely useful to troubleshoot one particularly nasty production problem. Take caution, they are extremely vulnerable, whatever you have reading from the named pipe needs to sanitize the input carefully. Very cool explanation, and I learned that, oddly, pipes present as directories. I would have thought since they were a very early and very fundamental addition to UNIX that they would have their own type.

EXTREMELY useful in the context of AWS networking! Do you offer a course?

Amazing, thank you.

Hi josh.these videos on linux virtualization are some of the best i have seen on youtube. You clearly have a talent for teaching computer techology. However your great blog material is not available using link. Can you fix that because although your video material is excellent...having your blog would be even better. Thanks

This was driving me nuts for like 3 days. Thank you so much for this concise explanation and walkthrough! :)

This is an AWESOME (all caps) video! I've been a user of virtualization technologies in the data center for a long time and a Linux user my whole career but have never delved into the details of "how does this all hang together?", and this is just the kind of video I needed to get me started: an exposition which goes into concept details alongside the actual configurations, and not simply the usual "these are the commands you need" which as octetz pointed out "might not work on every distribution" and why. I cannot thank you enough for the quality you put out into the world here.

the blog post is unreachable :(

Your blog seem to be down :((((

Your website seems to be down :(

this is excellent.... i wonder if there will be another to showcase the different gpu virualization capability QXL/ Virtio options( pros/ cons and when to use or switch)...etc

Excellent explanation/learning. BUT no mention of promiscuous mode setting for some switches. Would that stop VM access? And in the past I have been successful doing similar setups using wicked/openSUSE but I have never gotten one to work bridging with WiFi adapter.

This is a great explanation, and you are a really great instructor! Thank you for your time and effort.

Thanks Josh. It is a very didactical explanation, and a great contribution to the community. I have suscribed to your channel

i was starting learn since 1995 year

In Direct mode, the natOutgoing is set to true, but the capture showed pod ip's as source. Shouldn't this be source node ip?

Great tutorial, Thank you so much

Great video, default was missing for me too much tinkering :/ to get it to work.

Sos un capo, me solucionaste la vida

makes me wanting to learn go for cli tools especially with the named pipes. If I understand correctly, as long as there’s a process reading from the named pipe, I can use it as a listener for whatever I want it to take as input from a separate process.

Great video and great explanation.

As a filthy gui user... I wish virt managers ui was like vmware for connecting to the lan network with a simple toggle 😭 Its the 1 and only thing virt mans gui setup has let me down on

Josh, WTF are you talking about. Are you high on something ?

This is such a great tutorial. Sadly, though, I can't reach your website. Is it down?!

This is the best explanation I have seen of this particular topic I have seen so far. You are a fantastic teacher, and your depth of knowledge is really impressive!

good one thanku

Hi. The link to the blog seems broken.

I'm trying to utilize another static IP addresses from my dedicated server for my VMs. I'm having an issue trying to get bridge setup and adjust my /etc/network/interfaces to not use it on my dedicated machine but allow my VM to use that static ip by bridging it.

Your Blog post site is down. Any other link?

Bro my eyes... make this in a darker background fgs

Bad thing: the website hosting your blog post is down now.

fantastic details for cloning machines without using same ip address this is vitally necessary to know....

HI Jason! Thanks for such an excellent video. I learned a ton! Just wanted to point out that I clicked on the blog post link in the description and the link appears to be broken. It showed a pretty Cloudflare error page, but no content.

insert method is wrong i think..the if lastInsert == nextRead will be true after first insert. If the nextRead is 0 on init then after insert first insert lastInsert is 0 then the statement is true and you will move the nextRead to 1 and so one and so one. Solution would be to check if the last value of ring buffer N-1 is null or not if is null that mean you yet didn't fill the whole ring buffer else if there is value already then it make sense for the nextRead to move

How i missed this. This is great

Good stuff.. ty

neither of the links work. Is your site still up. It is a great video by the way.

Hey Josh! Well done video and well explained! Thank you for the content!

This video is top notch!!! Do you have any recommended books / info to start learning about linux?

the best video about calico routing

Ooof what did I run into? Was just looking a solution to enable my gaming VM access the internet. This just made me more confused. :D

Such a great presentation.

Hey John, the blog seems to be down.

This is the best video on youtube about this topic I have found. It has help save me a ton of work. Thanks a lot

VMware workstation can have a bridge and NAT configuration used on the same physical interface for different VM's. Is that possible with libvirt?

Very grateful for your methodical hands on approach with thorough explanations....

wow, simple

This rocks so hard

This video helped me clarify a lot of the concepts I was muddling through as I build my first home lab! Really appreciated your explanations both in concept & practice!

Firstly, thanks for the video, really informative! Could you please suggest how to extend the first simple bandwidth shaping example by adding some network latency (e.g. 60 ms) at the same time?
