a simple network question

Filed under
Hardware

Hello Forum!

I have a simple network question. I have a Linux Distribution on a lapton and I have the network hardware ready so so that I can connect to the internet. I already have a computer connected to the internet. So I suppose in order to have two computers I need some sort of hub device. Can anyone offer a suggestion about this?

Hub

So I guess I can just go to my local electronics / computer parts store and buy a hub. I wonder if my internet service provider needs to be informed about all this.

re: hub

A hub won't work if you only get 1 public IP from your ISP.

As mentioned, you probably need a cheap cable/dsl firewall (hard to tell exactly since you don't give the details of your existing setup).

Not only does that do the NAT (so you can have numerous private IP's and only 1 public IP) but most come with both a WAP and wired ports. For a few bucks more, you can get one that does SPI, which adds a layer of protection to simple NAT'd firewalls.

I wouldn't obsess over the brand, all the cheap ones (i.e. $40-$80) perform pretty much the same functions and for that price - anything over a year of 24/7 operation is bonus time in my book.

re: hub

well, a hub would work if he wanted to do masqing and forwarding through his desktop. Set up dhcpd or use static internal ips... even a crossover cable would work for connection sharing if he's trying to get by real cheap.

But yeah I agree the best advice is to get a router with the built in firewall and forwarding stuff. As stated, I'd suggest a wireless router so he could fully enjoy that laptop.

Get a router

It's unclear from your initial post whether you

- want to configure the computer you already have connected (to...what...a cable modem?) to share your Internet connection with other computers (which would also require two NICs in that PC, right?) or
- if you're just looking for the easiest way to connect your (let's assume) cable modem to more than one computer.

Getting a router, connecting your cable modem to it, and then connecting multiple computers to the router's ports would be the easiest solution (unless you know or want to learn how to configure a computer to act as a router).

Plus you'd get the benefit of the router acting as a firewall, since they usually do NAT. And Internet connection setup would also be very easy, since routers usually do DHCP.

(My experience with Netgear is good. I have an old (out of production) Netgear RP114 that's been solid. When we got wireless laptops, I bought a (ubiquitous) Linksys WRT54G to replace it, but found that the Linksys choked on bittorrent traffic, which caused me to have to frequently reboot the cable modem. So now the Linksys is plugged into the Netgear and is acting as a switch.)

As long as you've just got a half dozen computers or less on a home network with a broadband connection, you usually don't have to tell your ISP. But read your TOS to be sure.

(I defer to Susan. She's got way more experience than me.)

re: network question

Well, if you're going to do the firewall/forwarding from the desktop, a hub would work - or even just a crossover cable and another nic. But if you'd rather let the new device do the forwarding, then get a switch. Most have a firewall built in that will forward traffic to and from your cable or dsl modem. Any good commercial switch will work. In fact, if it's a laptop, you might even prefer to get a wireless router (which have rj-45 slots for your desktop).

I've had some bad experiences with netgears, in that they don't seem to last long. dlink and linksys are pretty good I reckon.

Pumpkins, markets, and one bad Apple

Imagine your local farmers market: every Saturday the whole town comes together to purchase fresh and homemade goods, enjoy the entertainment, and find that there is always something for everyone. Whatever you need, you can find it here, and anyone can sign up to have their own little stand. It is a wonderful place, or so it seems. Now, imagine starting out as a pumpkin farmer, and you want to sell your pumpkins at this market. The market owner asks 30% of every pumpkin that you sell. It's steep, but the market owner -- we'll call him Mr. Apple -- owns all the markets in your area, so you have little choice. Let's continue this analogy and imagine that, since it is a little hard for you to make ends meet, you decide to tell your customers that they can come visit you at your farm to purchase pumpkins. Mr. Apple overhears and shuts your stand down. You explain that your business cannot be profitable this way, but the grumpy market owner says that you can either comply or find another place. At the end of your rope, you look for information about starting your own farmers market, but it seems Mr. Apple owns every building in town. In the midst of Apple announcing its new products, attention is drawn away from its ongoing battle to maintain its subjugation over users globally. The Netherlands’ Authority for Consumers and Markets (ACM) last month informed the U.S. technology giant of its decision that the rules around the in-app payment system are anticompetitive, making it the first antitrust regulator to conclude that the company has abused market power in the App Store. And while Apple is appealing this verdict, the European Union is charging the company with another antitrust claim concerning the App Store. Read more

Development version: GIMP 2.99.8 Released

GIMP 2.99.8 is our new development version, once again coming with a huge set of improvements. Read more Some early coverage:

  • GIMP 2.99.8 Released with Clone Tool Tweaks, Support for Windows Ink

    A new development version of GIMP is available to download and it carries some interesting new features. While this isn’t a new stable release — GIMP 2.10.28 is the most recent stable release (and the version you’ll find in Ubuntu 21.10’s archives) — the release of GIMP 2.99.8 is yet another brick in the road to the long-fabled GIMP 3.0 release. And it’s a fairly substantial brick, at that.

Mozilla: Six-Year Moziversary, Thomas Park/Codepip, and Weak Response to Critics of Firefox Spyware

  • Chris H-C: Six-Year Moziversary

    I’ve been working at Mozilla for six years today. Wow. Okay, so what’s happened… I’ve been promoted to Staff Software Engineer. Georg and I’d been working on that before he left, and then, well *gestures at everything*. This means it doesn’t really _feel_ that different to be a Staff instead of a Senior since I’ve been operating at the latter level for over a year now, but the it’s nice that the title caught up. Next stop: well, actually, I think Staff’s a good place for now. Firefox On Glean did indeed take my entire 2020 at work, and did complete on time and on budget. Glean is now available to be used in Firefox Desktop.

  • Mark Surman: Exploring better data stewardship at Mozilla [Ed: Mozilla fails to admit that spying on Firefox users is wrong; now it's misframing the criticism and responds to a straw man]

    Over the last few years, Mozilla has increasingly turned its attention to the question of ‘how we build more trustworthy AI?’ Data is at the core of this question. Who has our data? What are they using it for? Do they have my interests in mind, or only their own? Do I trust them? We decided earlier this year that ‘better data stewardship’ should be one of the three big areas of focus for our trustworthy AI work. One part of this focus is supporting the growing field of people working on data trusts, data cooperatives and other efforts to build trust and shift power dynamics around data. In partnership with Luminate and Siegel, we launched the Mozilla Data Futures Lab in March as a way to drive this part of the work.
