Is presume the client would use eth0 as its def gw? All due respect to the webmaster, I see several problems with this configuration. Routers are used to break up broadcast domains, so instead of having two interfaces in Also, since eth0 has a default gateway of That scenario would be a better fit sir. Kind regards and thank you for your post. Admin Lin. Well, in above experimentation, eth0 the router in fact and the client were in the same network.
And IP address of eth0 was the default gateway for the client. Plus 1 for you. I cannot find the gateway Can you show me where it is. This experiment was performed in the college campus and the gateway If Any ideas?
Lots of crap may happen while using abovemention configuration. Otherwise half of sites won't work. Otherwise you may face specific TCP ports unreachability. Other tricks may involve MTU lowering. Consider that. I read your post. Thanks so much! If Host A and Host B are in the same network, there is no need of a router! I tryied with host A and host B in differents networks but it doesn't work : Any tips???

Running a router, network attached storage, and other services on only one device, especially without using VMs, is not recommended by IT professionals unless you are a cheapskate or college student. This is largely dependent on the number of hard drives you have. There are really lots of options here.
Keeping with the quick, simple, and dirty nature of this how-to, these instruction will be for a 4 or 5 HD system with 2 NICs. There will be no performance tuning or advanced options addressed. The process should be relatively self explanatory. Choose manual partitioning.
In the manual partitioning dialog, choose one disk to be your main booting disk. Format with: 0. Format all other disk as linux raid There will now be an option at the main partitioning dialog to create RAID device. Choose this option and select the appropriate RAID for your disks. If it's RAID 5 with 3 disks, then 3 devices, etc. The installer will ask you to reboot the installer. Do so. Go through installer again until you get to partitioning.
This time a raid device will be listed as a disk for partitioning. Continue with server install. Once server is installed, you will boot to a command line. Log in. Check that your RAID exists: cd into its directory and make a file, delete it.Jump to navigation. For the last few months, I've been talking a lot about using a bare install of standard Linux distribution as a router.
And I have to tell you, the homebrew router has been one of the more controversial topics I've ever written and presented about—some people love the idea, but the ones who don't seem to really, really hate it.

To be fair, setting up your own router from a generic server distro isn't a project for everyone. It certainly isn't user-friendly, both during the build process and once it's finished. While it's not terribly complexit's definitely arcanewith absolutely no hand holding along the way. If you aren't already very experienced with Linux, you'll likely do a lot of puzzled head scratching and maybe a little cursing. You won't get a super feature-rich build once you're done, either—unless you go on to do a lot more for your build than I have with mine, you won't have fancy quality of service features, usage graphs, or much of anything else besides a bare-bones although extremely high performance router that hands out IP addresses, resolves DNS records, connects to the Internet, and makes packets go where they're supposed to.
I don't have a problem with anybody pointing out any of that. Heck, I point it all out myselfand usually in the first couple of paragraphs. OK, let's talk about security for a moment. Security isn't something you tack on after the fact, or build on with a few thousand more lines of code.
Security is a mindset, and it's a design —it's something you build in from the foundation. Heightened security is actually the entire reason why I built my own personal bare linux router. Proprietary router firmware often goes months or years between upgrades—and when it does upgrade, it's more frequently to add some shiny to the UI—more than likely introducing more bugs—than to fix security problems.

Open source firmware isn't really in much better territory. DD-WRT is one of the most popular, and while it has a new and incredibly bug-ridden beta release every few weeks, the project hasn't had a stable release in eight years.
Eight years! It also goes months or longer between firmware updates being made available, with again no real guarantee that an update won't change major parts of the UI and the capabilities, not just fix bugs. For a lot of people—and businesses, don't get me wrong—that's perfectly fine.
For my own personal network, it's no longer good enough. I wanted something minimalin which I knew every inch of the actual configurations because I'd written it myself.2000 yamaha venture snowmobile specs
And I wanted truly frequent security updates, with the kind of quality assurance and testing that a major distribution brings to the table. The little specialty router distros can't help but be also-rans at this. And that's where my homebrew router came in. No, it's not "less secure" than a router distro—it's got far, far fewer moving parts, and I know all of them well.As we have anticipated in previous tutorials of this LFCE Linux Foundation Certified Engineer series, in this article we will discuss the routing of IP traffic statically and dynamically with specific applications.
Linux Foundation Certified Engineer — Part The iproute package provides a set of tools to manage networking and traffic control that we will use throughout this article as they represent the replacement of legacy tools such as ifconfig and route.
The central utility in the iproute suite is called simply ip. Its basic syntax is as follows:. Where object can be only one of the following only the most frequent objects are shown — you can refer to man ip for a complete list :.
Whereas command represents a specific action that can be performed on object.
How To: Build a Simple Router with Ubuntu Server 18.04.1 LTS (Bionic Beaver)
You can run the following command to display the complete list of commands that can be applied to a particular object:.
The above image shows, for example, that you can change the status of a network interface with the following command:. The first column in the output of the three commands indicates the target network.
The output of ip route show following the keyword dev also presents the network devices that serve as physical gateway to those networks. Although nowadays the ip command is preferred over route, you can still refer to man ip-route and man route for a detailed explanation of the rest of the columns.Peugeot 5008 automatic gearbox problems
We want to route icmp ping packets from dev2 to dev4 and the other way around as well note that both client machines are on different networks.
Another scenario where a Linux machine can be used as router is when you need to share your Internet connection with a private LAN. In addition to set up packet forwarding and the static routing table in the client as in the previous example, we need to add a few iptables rules in the router:.
This was the result of running:. Nowadays, the tool most used for dynamic routing in Linux is quagga. It allows system administrators to implement, with a relatively low-cost Linux server, the same functionality that is provided by powerful and costly Cisco routers. The tool itself does not handle the routing, but rather modifies the kernel routing table as it learns new best routes to handle packets.
That is why you will see a lot of reference to zebra from this point on. Please note that it is not possible to cover dynamic routing and all the related protocols in a single article, but I am confident that the content presented here will serve as a starting point for you to build on. We will use the same environment as with Example 3, with the only difference that eth0 is connected to a main gateway router with IP Note : That ripd.
Note that this is only one of the protocols that can be used along with quagga, and I chose it for this tutorial due to easiness of use and because most network devices support it, although it has the disadvantage of passing credentials in plain text. For that reason, you need to assign proper permissions to the configuration file:.
In this example we will use the following setup with two routers make sure to create the configuration files for router 2 as explained previously :. Connect to zebra listening on portwhich is the logical intermediary between the router and the kernel:.
If you want to try different protocols or setups, you may want to refer to the Quagga project site for further documentation. In this article we have explained how to set up static and dynamic routing, using a Linux box router s. Feel free to add as many routers as you wish, and to experiment as much as you want.

Some of the distributions mentioned here are also a part of the best Linux distributions for beginners. While our focus is on older computers, you can also use most of these lightweight Linux distros on relatively new hardware. This will give you a better performance if you use your computer for resource-heavy usage such as video editing on Linux. Note: The list is in no particular order of ranking, take a look at the minimum system requirements to choose one for yourself. Slax is a really portable lightweight Linux distro based on Debian which you can use it on a USB drive without installing it.
The user interface is simple and usable with essential pre-built packages for an average user. You can even try to customize the OS and make permanent changes on the fly if you require it. In addition to the desktop support, you can also try it on a Raspberry Pi or Jetson Nano.
Zorin OS is an Ubuntu-based Linux distribution. It offers a lite edition for older computers that features the Xfce desktop environment.

If you have a decent system not too oldyou can also try the regular Zorin OS to see if it fits your purpose. Xubuntu is one of the official flavors of Ubuntu that features the lightweight Xfce desktop. You will find it easy to use and can also install it on your older computers with no issues.
If you have a decent hardware configuration refer to the minimum requirements belowLinux Mint Xfce edition will be a great option to have. While being an Ubuntu-based distro, it also features the Xfce desktop which makes it good enough for some old computers. Considering that Linux Mint as one of the best Linux distrosyou can also try other editions like Cinnamon available.
Originally created with the web-centric approach of netbooks in mind, Peppermint includes the ICE application for integrating any website or web app as a standalone desktop app. A dedicated forum also exists to help troubleshooting issues and answering your questions.
Next on our list of best lightweight Linux distributions is Lubuntu. From Ubuntu In fact, it is one of the official flavors of Ubuntu. Lubuntu supports older computers that have been buried Just kidding! You can also use Lubuntu on modern hardware. Lubuntu is one of the lightest derivatives of Ubuntu so it specializes in speed and the support for older hardware. Lubuntu has fewer packages pre-installed consisting mostly of lightweight Linux applications.Menu Menu. Search Everywhere Threads This forum This thread.

Similar to webmin but more task-specific. Google searches just bring up the aforementioned router distros, i. Alternatively a router distro which can support the services, or even virtualbox would work I suppose.

I know that this is not how a true admin would do it, but this is for a small home network and for a person who's not very comfortable with the command line iptables configuration.
There's a small home network with a shared DSL connection funny, huh? There's currently an Ubuntu server 8 box in front of the DSL modem to shield the modem from eventual flood why's the flood - let's say we can't control it and the admin would also block the internet access for some users using iptables on the server.
Is there any built in or freely available GUI tools to simplify network configuration on linux? He could switch to a desktop version of ubuntu and remote through VNC, that's not a problem and it is not a production environment so security is not that a big consideration, neither is performance. Some distributions include Webminwhich is a web based interface for system administration. For Ubuntu, I would first try apt-get install webminbut if that doesn't work I found an installation tutorial for webmin on Ubuntu If this is for a small home network where no one is really comfortable with iptables, why not get a little Linksys or comparable home router?
You then get a pre-packaged device that is specifically designed to handle that sort of setup and you get an easy-to-use web interface to configure any sort of advanced configuration you may need to do port forwarding, etc. Setting up a Linux box on the edge like that without having some working knowledge of networking, IPtables and even what is running on the box could very easily lead to a compromised Linux box. If you wanted to get fancy and keep with the Linux theme, you could get an OpenWRT supported device and use that.
Then you get the best of both worlds: a dedicated device for handling network traffic as well as a Linux system filtering the traffic for you. Both are super simple to use and should provide the control you are looking for with minimal fuss.

I agree, I'm pretty comfortable with it. Its not for me personally and the person is not very comfortable with the command line thing, its not even the concept of iptables, just the fact that one has to type ommands instead of working with a GUI.VyOS 1.1.8 Installation (Open Source Router) + Overview on Oracle VirtualBox 
I've looked at the webmin tool and it doesn't seem to abstract the concept of iptables in any way. So I think here it is just a matter of personal preference. Corey S. I agree that a router device would be better, the problem is they didn't have money for such a device and used an old box someone wanted to get rid of and was glad it would be taken away for free.
But such a device would be a good consideration in the future. Sign up or log in Sign up using Google.
