Setting up Home Network Via Modem/router.

[phonnic_p]

I have just spent 40minutes ping pong-ing forums and guides looking for documentation on how to set up my two Lucid PC's with a home network via my Modem/Router.

I would GREATLY appreciate some assistance in either pointing me to the right documentation (a step by step guide would be awesome) or If you're willing to help me by just telling me what it is i need to do.

On both PC's is current updated (Kernel23) LUCID, one connects to internet via Ethernet, the other via USB. The Modem (Dynalink RTA1320) is also a router and I've had it networking a dualboot pc and laptop via windows in the past.

Thanks in advance for any assistance.

Now to take advantage of the rare winter sunnyday and weed the garden till there is a response or it gets dark!

Re: Setting up Home Network Via Modem/router.

I'm not sure what you mean by "connects to the internet" in this case - perhaps because I've never done USB networking. (Is that even possible?) I would assume your router is the only thing which is connected to the internet and that the computers are both connected to the router. That is the usual, and expected, configuration. Could you explain in more detail please?

Re: Setting up Home Network Via Modem/router.

OK, I have Two PC's one is Intel E6500 CPU - 4Gb Ram- Asus EN9500GT 1Gb GPU....with an internal Ethernet port (No additional Network cards are installed) running Lucid 10.04(64) LTS Kernel 23, which shall be known as pc1. The second (pc2) AMD athlon64 1Gb Ram and An internal Ethernet port with a network card installed also running Lucid 10.04(64) LTS Kernel 23.

Now I do know home networking would be easier if I just connected pc2 to the Modem/Router via an Ethernet cable to the internal motherboard port and connected pc1 to pc2's network card.

BUT I have the two PC's connected to the same Modem-Router pc1 via Ethernet & pc2 via USB and wanted to try networking that way.

Re: Setting up Home Network Via Modem/router.

I don't know whether or not your router automatically includes the USB connection in the LAN or not. If not then you may need to configure your router to do so. I can't tell you how to configure your router.

You need to decide whether you want to use automatic addressing (ie DHCP) or manually assign addresses. If your router provides DHCP service then this is the easiest thing to do. Configure all computers to use DHCP, which has been the default on all my Kubuntu machines. Reboot all the computers. If rebooting is not an option then you can manually bring down the network adapter on all computers and then bring them back up one at a time.

After the computer's network adapter is brought back up you can check the address and subnet mask it received from DHCP using the ifconfig command. Check the addresses to make sure they are on the same IP network. Then use the ping command to test for connectivity between the computers.

Congrats, you have a network! (Hopefully anyway.)

This was done after reading Telengard's post with no alterations to anything both PC's are able to connect at the same time.
How do I ping?

[Ole Juul]

Re: Setting up Home Network Via Modem/router.

Type

ping 192.168.1.2

or 192.168.1.3 or whatever number you are trying to ping.
You can also use names such as:

ping google.com

Ctrl-C stops it.

I'm not sure I really understand you here.
Does your modem/router have more than one ethernet port?
If it does, the easiest way to get things working would be to connect PC1 to one ethernet port and PC2 to another ethernet port.

Re: Setting up Home Network Via Modem/router.

The fact that he is connected to his router via a USB is immaterial. If both computers are connected to the router, no matter how they are connected, he just needs to set up his network. I recommend NFS as the fastest and most reliable method. Take into account that file transfers would be much faster if both computers were connected via ethernet.

This is a very good step by step guide on setting up NFS.

That is the way it should work in theory, yes.

Did I miss the part of his OP where he asked for a sharing protocol? Even if that is what he really wants, don't you think you are getting too far ahead of the situation? We don't even know whether his computers can talk to each other yet.

Re: Setting up Home Network Via Modem/router.

Maybe he should just ping each computer from the other computer to see if they connect.

Agreed. That's why I already suggested it and Ole Juul showed how
