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.
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.
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
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.
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!!
when router doesnot have destination mac in Mac table then as it is collision domain it will not broadcast and simply drops it so to avoid this we use default gateway this is where to send packets when router dont know ehere tto send
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?
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.
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?
@@pauraspatil9314 pivoting and creating ip tables is very important, learn it properly. And everything you need is covered in the study material and labs. Best of luck 🤩🤩🤩
Would have liked to know what the metric column is for. What if mask is the same as in your last two entries? Which one will it use then? Will it use wlan0 or eth0?
The metric column acts as a tie-breaker when an IP matches several entries successfully. That example is not ideal because the last two entries match the IP, even if using metric (of 0). In that case, the FIRST item will be selected (here, wlan0). The order in the table acts as a tiebreaker. netbeez.net/blog/linux-set-route-priorities/
Sir, I have a question here. I suspect some hackers hacked my macOS through kernel. But when I type # route, it did not show kernel IP address, but shows usage: route [-dnqtv] command [[modifiers] args]. My WiFi connected to hackers fake WiFi 78:65:59:70:9c:19 and when I use Ethernet it connected to hackers too: 01:00:5e:7f:ff:fa.
7:18 where's the tutorial about the vm router please? I've just setup a vm router but am confused on the packet routing and how to diagram the connections using $ route command?
I’m a routing table there is no music sounds or notes I’m positive but I feel strongly towards it I I’d use because at default you cross at least 222 faults under default and having one especially at home can be a symptom to a problem better off checking it some people “” more frequently check theirs very often why ??
Which command to add IP address and its MAC address to a macOS routing table? Route add -host 192.168.1.254 -link MAC address The ‘link’ in that command is wrong, isn’t it? I added the correct gateway but after 2 minutes it reverted to hackers MAC address again. Is there any way to solve this?
Help. When I enter sudo ip -6 route del default and add a new one, sooner or later the new route disappears and the old route returns. I need it gone; it links to a link-local-adress that is gone. And I can't get route to work with IPv6. Doesn't do what the tutorials show.
The reason it is showing _gateway is that the "route" command is trying to resolve the name of the IP. You can use route -n (to stop route command resolve the IP --> name).
Please, bear in mind, I am very new to CS and developing, but I have been following this playlist of videos. Around 0:40 Bucky is talking about viewing your routing table, and he says "if you're on Linux..." and proceeds to explain from there. I am brand new to Linux, and I see someone else mentioned Kali and I see root@kali at the top of the browser. I investigated Kali a bit off of that, and have some questions. Is this another OS that he is running in conjunction w/ Windows? Trying to follow along. I am downloading Kali Linux Light right now in the hopes that I'll find my answers there. Just putting out more lines. Thank you!
Mike Filicetti I'm not aware of his setup but it might well be a VM running Kali Linux. Beware the light version might not have a desktop environment so if you are new to linux the console might be a bit daunting.
I don't believe this statement is correct in modern applications and the routing table. Metric is also used to create priority for interfaces in routing daemons as well.
The “cost” of the route. The metric is used to sort duplicate routes if any appear in the table. Beyond this, a dynamic routing protocol is required to make use of the metric.
listen you can connect your pc to a router by using ethernet cables or wlan wifi methods , this is just the way you will sent and receive packets from your router ,but the default gateway is how your router is connected to internet , and i'm 100% sure that you have a adsl cable network installation so it' normal that your router only use cable as a default and not wifi ,hope that i was clair ps even 3g and 4g from what i know use cable connection but just use cables to connect to internet it's just that they broadcast the signals using big antennas so even 3g 4g ..and satelite are in nature Ethernet connections
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).
