Internet configuration post-install.

[dr pepper]

My gentoo system is fully fuctioning with the exception of the internet. The only problem that i have right now is the fact that i forgot to install dhcpcd. How do I configure my internet from here?

with ifconfig i get:


eth0 Link encap:Ethernet HWaddr 00:07:e9:c6:44:72
inet addr:192.168.0.2 Bcast:192.168.0.255 Mask: 255.255.255.0

When i ping gentoo (ping -c3 www.gentoo.org, I get an error message that states

ping: unknown host www.gentoo.org

Assuming

• /etc/hosts
• /etc/conf.d/hostname
• /etc/resolv.conf
• /etc/conf.d/net

are configured as per the Gentoo Handbook, you can do it now (adjust to match your net.eth<number>):

Code: Select all

emerge dhcpcd
/etc/init.d/net.eth0 start

Check it with:

Code: Select all

ifconfig

Test it with:

Code: Select all

ping -c3 www.gentoo.org

i think i may have made an error when I configurated /etc/conf.d/net because it is configurated like:

config_eth0=( "192.168.0.2 netmask 255.255.255.0 brd 192.168.0.255" )
routes_eth0=( "default via 192.168.0.1" )

but when i look at my ip config in windows i get:

IP adress 192.168.1.96
default gateway 192.168.1.254

how should my files be configurated if this they are incorrect

[Mike Hunt]

Then it should be (assuming you are using stable Gentoo):

Code: Select all

config_eth0=( "192.168.1.2 netmask 255.255.255.0 brd 192.168.1.255" )
routes_eth0=( "default via 192.168.1.1" ) 

And /etc/resolv.conf should be

Code: Select all

nameserver 192.168.1.1

And /etc/hosts accordingly.

That's assuming that no other computer connected to the same router is using 192.168.1.2

In the case that it still doesn't work, then go ahead and use the same numbers as the windows box:

Code: Select all

config_eth0=( "192.168.1.96 netmask 255.255.255.0 brd 192.168.1.255" )
routes_eth0=( "default via 192.168.1.254" ) 

And /etc/resolv.conf

Code: Select all

nameserver 192.168.1.254

when you say configure /etc/hosts accordingly, do you mean
192.168.1.2 localhost
::1 localhost

also with the alternetive liveCD method, i have deleted the tarballs as per the manuel. Must i download the tarballs and remount my hd to chroot into it?

[Mike Hunt]

/etc/hosts should have at least a line something like this (of course adjust hostname accordingly):

Code: Select all

 127.0.0.1 mybox.at.myplace mybox localhost

or even something like this:

Code: Select all

127.0.0.1      localhost.localdomain    localhost
192.168.1.2    mybox.at.myplace         mybox
192.168.1.3    otherbox.at.myplace      otherbox

I'm not quite sure if you need any ipv6 configuration. You do if you know that you do.

[dr pepper]

bear with my lack of knowledge, but how do i find my domain domain name, mybox...
are they just the names of my router and my dsl box
does my connection-specific DNS Suffix matter?

[eXess]

"myplace" and "localdomain" stand for local domain.
The name of this lomain depends on your need to match existing Windows domains / workgroups.
If you do, use correct names. Otherwise, "local" or anything seems fine.
It's set (by you) in /etc/conf.d/net

"mybox" stands for the name you decide to give to your machine.
It must (should?) be unique on the local network and respect classic naming conventions (no spaces, etc).
It's set (by you) in /etc/conf.d/hostname

To set all this, read : http://www.gentoo.org/doc/en/handbook/h ... #doc_chap2

Hope this helps.
