Till now, I was thinking that networking needs lot of knowledge (of course, it needs) but you made it so simple for the beginner. Now I can practice the stuff with a good understanding rather than copy-paste from web. Thanks to you Eli.
sir, you are a king of windows and linux....no one beat you on this.............. you explained all classes i'm really easily understand. thank you very much
Eli, I just wanted to say, I have been viewing your videos for a few weeks and you are very informative. I am currently learning Linux to better myself in the computer industry and the way that you explain and teach is unrivaled so far. You take a very dry and bland text subject and turn it into an easy to learn atmosphere. You are doing a great job and hope you keep it up. Thank you again man!
Thank You Dude, I've been feeling like an idiot until I saw this and realized I just needed some motivation and to hear a voice say the stuff I was reading in a book.
Resolvconf gets populated with information by a set of hook scripts related to network interface configuration. The most notable difference for the user is that any change manually done to /etc/resolv.conf will be lost as it gets overwritten each time something triggers resolvconf. Instead make your change here > /etc/network/interfaces add this line to your interface "dns-nameserver 192.168.1.5" without the quotes of course.
You can use a 24-bit subnet mask with a Class A (10.x.x.x) IP address. If you're getting an error when you're trying to set this on a router, remember that you have to have the command "ip subnet-zero" enabled. Otherwise the router will look at the first octec of the IP address and sets the default mask to that range ..... 10.x.x.x=/8 172.16-31.x.x=/16 192.168.x.x=/24. I hope that helps
10.0.0.0 is a private reserved address range. It is not routeable and is one of the address ranges organizations use on LANs. It gives you a large pool of addresses.
It seems the init.d/networking restart is deprecated hence you have to use the following sudo ifdown -a "to turn off" sudo ifup -a "to turn on" correct me if wrong.
Thank You for this. I was having trouble with the sudo /etc/init.d/networking restart. It was not updating my network settings after changing the interfaces file. I tried your method and it works nicely.
Just to let you know that you can also put more than two DNS addresses in windows to. You just go to advanced settings of network adapter properties. Also u rock !!!!!
Thanks for your efforts here. I've always dived head first without learning the basics. Makes so much more sense now it's like turning a light on. Cheers
Great detailed tutorial on linux networking. I see a lot of comments about things needing to be done a certain way but there are multiple ways to do the same thing on Linux systems. Good job!
TTL= TIME TO LIVE. That is a counter, when it gets 0 the package is killed, it the maximun size is 255. Wheneve a ping pass through a switch or something this ttl gets minus 1, until it gets 0. When gets 0 the package is killed for it does not keep going around using bandwidth unecessary. For change the ttl, you can use a parameter -t [NUMBER] ping -t 255 [site or host] Hope this helped.
UFW firewall is pretty much the same on other distributions other than Ubuntu. For example, I still type the same commands for UFW running in Arch Linux to deny certain traffic just like I would do on my Ubuntu server.
Fantastic tutorial!. One tip... if you want to save time; watch only the explanations over the the terminal. It is basically a carbon-copy of what Eli says on the whiteboard.
@Badboysvsgoodboys It will keep giving you the same IP unless the server decides to assign a different one. If you need a specific IP you need to edit the interfaces file.
thanx for the way of teching whatever i am not able to understand in lectures i come and browse your video and it becomes as simple as a cup of tea.....
No, you don't need to pay anything to host server (except indirect cost of running computer), besides there lot of solutions that runs severs on your computer and most likely you not even aware of that. If you have LAN you need to forward server port from your computer to public IP (IP on internet side) in router configuration, you use that port for minecraft server and it should work :) without that only computers in LAN will be able to connect to it
Keep up the great work! This video was so useful!!! Straightfoward, clear, and knowledgeable......As long as you keep making videos, I will keep watching! You earned an instant fan!
no doubt, a mess is right. I stumbled across your channel thankfully trying to figure ssh,etc, after getting wifi finally and feel like I'll never get all of this. anyway thanks for making these videos. 🙂
Thanks a lot for the video! Somehow it help me fix my network. I have no idea what I did to fix it. Next time I have a networking problem, I will reference this video.
Fantastic content. This covered a lot of information that I've had trouble understanding in the past and have had to find explanations on all across the web.
hello eli the computer guy.. your are good in ur profession I like your videos and able to understand everything.. please can you send me link of videos by you.. or where I can download all of them?
Great tutorial. I have used this video many times to reference. I would like to see video more in depth on ufw and iptables. I have found myself stuck in filtered.
@123456iambelial Nevermind, i figured it out. For those who does not know you would need to edit two files: /etc/hostname and /etc/hosts then just change the current hostname. The /etc/hostname there should be only 1 line, so change that then for /etc/hosts there are 2 hostname you need to change and both are located in the 2nd line. Cheers
Great video, but you should've mentioned that sometimes PING won't work because the destination device is configured not to respond to it for security or whatever reasons. It might save some trouble to some folks! :) Cheers!
careful if you are watching this video and install the 15.04 version that some stuff are slightly changed. so if something doesn't look the same when you enter it, you'll know why. there are great picture tutorials easy to find.
Hey Eli, you videos are great. It keeps me engrossed. Would you ever do a topic on SElinux. I did use audit2allow commands and set Boolean values from log files to troubleshoot in our lab envoirment. It will be great to see a video from you about SElinux.
great video. helped me refresh my memory of some networking bits i had forgotten. One little gripe: this is debian oriented. that's fantastic and it's really great for linux noobies and debian users, but i was actually looking for a way to configure my CentOS box but this class doesn't cover red hat based distros. not knocking your classes because i've watched and learned a lot, but i would love it if you could cover red hat based networking/administration because it is slightly different.
Hello ELi I have a couple questions as I am a Network Security major and working primarliy in Linux. I am now learning OPENBSD..do you have any experience with openbsd, if so can you make a tutorial? My next question is for the UFW firewall used in other distro's other than UBUnTU? I am currently taking a firewalls class , and learning IPTABLES. Thank you for your help...great vids
The -r flag explicitly releases the current lease, and once the lease has been released, the client exits. For example, open terminal and type the command: To Release Ip address:- $ sudo dhclient -r Now obtain fresh IP: $ sudo dhclient
Should I be putting my xen dom0 on the same subnet? as my router to the outside or a different subnet? And then presumably the appliances would be on the same subnet as the dom0?
Hi, I am new user and I am learning so much from your video. They are the best I have watched so far found on the Internet. So I have a question. I am testing Linux Ubuntu on a virtual machine on a Windows 7 OS. When I do the network configurations, and then delete or shut down the VM; do all the configurations delete process? and do the Windows Network configuration remain the same?
ANOTHER AWESOME LESSON.... been watching nonstop since the first of your LINUX class... approximately 6hours straight hahaha :) Audio though are a bit out of sync for some
I recently installed a version of zorin linox and can see wireless connections available from system settings network menu but can not connect to any, is this something simple to fix please help!
Can you use the ufw allow port 80, port 25, port 110 etc. to make multiple ports allowed with one command line or do they have to be allowed on separate lines??
Hi Eli, and thanks for the great tutorials for noobs like me. i have watched quite few of your tutorials however i must have missed the one that teaches terms such DCHP, Subnet Mask, Static IP, DNS and stuff because i don't have these things cleared up in my mind yet. Which from your tutorials should i watch to learn these stuff? Don't get me wrong, i know what an IP is but some stuff i don't know them.
Ran into a serious problem. The terminal is not able to connect to the internet [not able to run apt-get upgrade or ping etc] but is perfectly working on the system's browser. Please, help me solve this problem. Moreover, when I run the dhclient command, the output is same as yours but the only difference is it shows "Reloading /etc/samba/smb.conf: smbd only". And also I'm getting the same message when I run the apt-get upgrade command.
IMO it's poor form to just type "ping [destination]" causing it to ping forever and then entering Ctrl+C to every time stop it. Use the option -c for count like this: ping -c 4 [destination].
hey eli, thanks for the very informative lessons. I have a question. if subnet mask is 255.255.255.128, then is the network address x.x.x.128? Thanks for reading.
whenever I echo the hostname after changing it, it shows " sudo: unable to resolve host new server: Connection timed out" followed by echoing the new name of the host in the next line.
HI, Thanks for the lessons... all of them. I've been having a problem setting my static ip address. In all my computers the file /etc/network/interfaces don't have from the line # The primary network interface... The first time i tried taking it away the loopback part from the file and changing it for static... well it didn't go very well it just destroy all of it, even my linux mint theme... after that try, I tried adding the lines from
First, thanks. Great videos. Second I have been working on a Beaglebone trying to network using wireless with poor result so far: So....I am seconding the idea of linux to (using a usb cable) windows networking.
When I type "sudo /etc/init.d/networking restart" I get a message that it is deprecated. Then if I try to "sudo /etc/init.d/networking start" it recommends using "service networking start" and just hangs; not letting me do anything else. I am using VirtualBox with bridged network connection, any suggestions?
Help me not know how to configure the network cards in had 7.6 I have two cards one eth0 and eth1 the first one is eth0 want it for internet and eth1 to connect to the internal network lan cave mention that the machine I'm using before had windows server 2000 and everything worked fine I've tried from the terminal to configure network cards in were worse can not get it to work apparently what I do on eth0 automatically taking eth1 good I got tired of trying to do in the terminal and I go to graphically configure eth0 putting a ip and dns I connect to the Internet but when I configure eth1 for lan amending eth0 and now I can not connect to the Internet feel that the two cards are one room even had me recognizes them as an individual but when set function as if they were one. tell me what I can do.
