Setting up a static IP

It has been a while since I had a try with arch linux. I hope this one will be the good one. It seems that my arch installation does not have the right networking setup.

I used the beginners guide and the installation went well using the ipxe.lkrn imageand everything went fine.
1.0 Until reboot where I wanted to install xorg-server with pacman.
2.0 I realised that pacman would not fetch the packages, I am working in root mode
3.0 I have a wired connection to a router and the same computer connects the internet with another linux distribution.

I have tried to setup internet connection in my new archlinux installation thru the proposed way of the beginners guide:
- the wired static ip method, my wired link name is enp2s0, and changed accordingly the /etc/dhcpcd.conf file backing up the original one thus the only info in the /etc/dhcpcd.conf being:
interface enp0s25
static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1 8.8.8.8

- ping www.google.com and ping 8.8.8.8 would yield host unreacheable

Here is the output of dhcpcd -k followed by dhcpcd:
wlp3s0: starting wpa_supplicant
dev: loaded udev
DUID 00:01:00:01:1d:8e:37:57:00:21:5d:c8:cd:8a
enp2s0: IAID 21:64:78:8e
wlp3s0: waiting for carrier
enp2s0: soliciting an IPv6 router
enp2s0: soliciting a DHCP lease
enp2s0: offered 10.0.0.17 from 10.0.0.1
enp2s0: probing static address 10.0.0.17/24
enp2s0: leased 10.0.0.17 for 86400 seconds
enp2s0: router 192.168.0.1 requires a host route
enp2s0: adding route to 10.0.0.0/24
enp2s0: adding host route to 192.168.0.1
enp2s0: adding default route via 192.168.0.1
forked to background, child pid 879

What is missing here to establish a wire internet connection.

Re: Setting up a static IP

https://releng.archlinux.org/pxeboot/ says:

"A computer that connects to the internet via LAN and DHCP."

So we can assume DHCP worked on the installation iso, including ping www.google.com ? From your log, it does seem you're getting a lease.

The question is, why are you trying to configure a static IP? Also, the values there should not be taken literally from the guide, but adapted to your config.

Re: Setting up a static IP

@alad:
Things went find with the iso.

I am not able to connect to the wired internet. So where do I read next on the config? Should I provide lspci output? The problem is that I am away from this first linux box. On this second one I would rather try to install in virtual box.

Re: Setting up a static IP

Restore the original /etc/dhcpcd.conf, disable the dhcpcd service (if you've enabled any), and follow the steps here:

enp2s0: soliciting an IPv6 router
enp2s0: soliciting a DHCP lease
enp2s0: offered 10.0.0.17 from 10.0.0.1
enp2s0: probing static address 10.0.0.17/24
enp2s0: leased 10.0.0.17 for 86400 seconds
enp2s0: router 192.168.0.1 requires a host route
enp2s0: adding route to 10.0.0.0/24

Those lines suggest your router is 10.0.0.1 and handles addresses in the 10.0.0.0/24 network range .
You are telling your pc to use the 192.168.0/24 network range, and use 192.168.0.1 to connect to outside world.
try pinging 192.168.0.1 , it will fail.

Use a static address in the 10.0.0.0/24 range instead.

Re: Setting up a static IP

@lone_wolfe:
Your remark makes a lot of sense. My router setup does not fit with the proposed address. I will look at this one, presently I am not on the same router.

Meanwhile working under a new installation under vbox trying to get networking going on, the network was not working.

I installed networkmanager and nm-applet with the help of the archlinux.iso thru the chroot procedure. Rebooted the system without the iso and started networkmananger with:
sytemctl start NetworkManager.service

Is there a way to start networkmanager automatically at each bootup?

Re: Setting up a static IP

This is what I thought meanwhile.

systemctl enable NetworkManager.service

did the job

I am begining to get the DIY philosohy, though it is really nice to have some people around, pinpointing or commenting.

Thanks.

Re: Setting up a static IP

u might aswell read the manpages, it is imho just not as beginner friendly as the wiki...especially when eng is not ur native languagge...
