[SOLVED] I'm having trouble setting up a wired connection.

I'm using:

ip addr

To get my network details... but I don't think I'm getting all of them. Per the Beginner's Guide, I need the following:

    Static IP address.
    Subnet mask.
    Gateway's IP address.
    Name servers' (DNS) IP addresses.
    Domain name (unless you are on a local LAN, in which case you can make it up).

Where can I get all of this in full? I don't need to contact my ISP do I? They're really a pain, so I'd like to avoid that. Thanks so much in advance for any help you can give me!

Re: [SOLVED] I'm having trouble setting up a wired connection.

I think you may be making this more difficult than it really is.   Describe your network.  Is it DSL, Cable, or are you using a larger infrastructure like a school or place of business?

In all likelihood, your ISP has provided you with a modem that has an Ethernet Jack that provided a private network.  The modem probably negotiates with the ISP for a public address, provided a firewall and NAT.  It also probably includes a DHCP server for the private network.

tl;dr:  What happens if you just run dhcpcd as root?

This is just for static IP. Do you need static IP?

Re: [SOLVED] I'm having trouble setting up a wired connection.

I'm installing from scratch on a machine with a wired connection. So, I'm just following the Beginner's Guide.

I have cable, Comcast to be specific. I'd PREFER a dynamic address but I'm open to whatever is best.

Are you saying I should just be able to throw in the ethernet cable and go?

Yes.  I would bet the grocery money that your modem has a DHCP server in it.

Re: [SOLVED] I'm having trouble setting up a wired connection.

Also, there is one more plot twist:

I am helping my brother install this on HIS machine, at my house, on my network. Then, later today, he's going to take his machine home and have to connect it to his network. So, we should probably go the dynamic route, since that's what most ISP use by default.

I greatly appreciate the help.

It should work there too

Re: [SOLVED] I'm having trouble setting up a wired connection.

Thanks @ewaller I'm going to start over and just put the ethernet cable in and try to ping the Google servers. Hopefully it will work. I'll repost if it doesn't automatically work.

Thanks so much.
