This dude is the pioneer of computer tutorials.

Thanks Bucky!!! I watched this video the night before my midterm, and this was exactly the same question on my exam. Thank you so much! Your videos have made my 4 years college life so much easier.

wow, 10+ years later, I still end up clicking into your tutorial! Kudos!

It's been years since highschool and I forgot newbosten taught me physics, java, python and even backgammon. He has risen to help me with my networking course haha

Once again, TheNewBoston saved my arse!

Thanks a lot! I was struggling with getting access to a service from a machine with multiple NICs (this was in a VPC environment) and this video provided sufficient information for me to be able to figure out that I needed to manually add a route in my table.

I'm time traveller from year 2050. Your tutorial still helps

[pinhead]

These videos are still relevant in 2021. Thanks

in middle of my eJPT exam, you saved my ass, thanks!

At the end of the video you say 192.168.0.15/0 is your IP. Isn't it 192.168.0.15/32, as that would be the subnet mask of 255.255.255.255, while /0 is 0.0.0.0. 192.168.0.15 with a subnet mask of 0.0.0.0 doesn't really make sense.

I love the way you explain everything. Gonna watch more of your videos. Good job

[funwisely]

Great explanation. Simple, relevant and clear. Thanks!

[jatin]

after listening to this video for some time I thought heyy this guy sounds a LOT like bucky i used to listen to back in high school. Scroll down a bit and it really was you lmao!!

[yzarc]

You don't explain what happens in this case when the destination matches two or more rules with the longest subnet mask. What is the conclusion for your example? Is the packet sent randomly to wlan0 or eth0? To both?

I have seen the flags in my router and never understood what they meant until watching this video. Thank you explaining so simply. I am interested in watching the video about windows routers because I have one but not sure where you have it.

[raulsanchez]

Thank you so much. Awesome explanation.

This is incorrect or poorly explained. If you send a packet to 54.123.2.2 (the ADDRESS), the routing code does the operation : ADDRESS & MASK = DESTINATION. So (54.123.2.2 & 255.255.255.0 ) => 54.123.2.0 and then (54.123.2.0 = 192.168.0.0) => false. The last one is done twice. Next (54.123.2.2 & 0.0.0.0) = 0.0.0.0 and then (0.0.0.0 = 0.0.0.0) => true [default is equal to 0.0.0.0]. For all the lines where the result is true, the routing code orders them by metric from small to big and sends the packet to the interface of the first ordered line (the smallest metric).

As mentioned on 7:20 where's the "How to turn your own personal computer into a router tutorial" ?

[pimguilherme]

Thank you for the awesome explanation!

What is chain of packet? electric/optic signal to network device -> convert electric/optical signal to binary code -> convert to frame -> convert to packet-> iptables -> ip route-> do something with this packet and send ancknowlegmets packets - > chain output iptables -> ip route -> convert frame to electrical signal\optical? Am I right or miss something?
