Hi, I can't seem to figure out how to set my ipaddress, subnet mask, gateway, and dns server. I'm very new to linux and don't know many commands.

Hi,
If you are using gentoo, I'd have a look at this manual... the best!

http://www.gentoo.org/doc/en/handbook/index.xml

If you are not, state your distro or do it all manually.

ifconfig can setup your network card
/etc/resolv.conf will hold your DNS information.

man is your friend

$ man ifconfig
$ man resolv.conf

Best of luck and keep in touch if you need more help... but if you do, we will need more info

Ed.

Ok here is the deal.
At school I need to have a "hard-coded" ip address and at work and home I use dchp.
I've used windows my entire life until now and I have been using gentoo for less than a month.
I'll take a look at the manuel but I honestly don't entirely know what to look for.

EDIT: Ok I found it in the manuel, is nameserver the same as a dns server on windows? Also, what is a broadcast ip for?

Welcome to Gentoo!

I believe all settings for your network can be found and configured in /etc/conf.d/net. Here you can specify DHCP, static IP's or whatever you need. If you need a more in-depth example, take a look at /etc/conf.d/net.example

And yes, "nameserver" is the same as a DNS server (Domain Name Server), as defined under the /etc/resolv.conf file. That file holds your nameservers. If you are using DHCP, then nameservers are normally added automatically, and if static IP is set, then you normally have to add a nameserver entry.

A broadcast address is basically the way your computer finds stuff on its local network. It sends data to this broadcast address and that data gets looked at by every network device on the local network. A broadcast address always ends in 255.

For instance if your IP is 192.168.1.123, then your broadcast address is 192.168.1.255. Every network device on that network 192.168.1.xxx's broadcast address is the same -> 192.168.1.255

Hope that helps,
Paul

If your computer has to juggle between static and DHCP you will have problems.

What I recomend you do, unless someone has a better idea, is to write a script you can launch when you are at school to set your static address.

So in short, set your network interface to use DHCP and then write a script that will set a static address if eth0 isn't up. I'm no good at scripting so no laughing ok

as root, run or add it to /etc/conf.d/local.start
