Trying to configure a network connection on Fresh installation!

zabrielza · 2015-03-03 11:32:33

Hello,

I am new here. I am trying to configure a network connection. I prefer to configure a static Ip connection. So, i want to follow this guide-article:

https://wiki.archlinux.org/index.php/Systemd-networkd .

At the bottom of the page Static ip Network is located. So my main question is what is container and what is host?

Also, i would like a tip if possible, My computer is connected to a switch which gives IP to many computers. For this situation what is best? DHCP or static IP?

Thanks in advance!

That wiki page was apparently written by someone who uses containers, and therefore decided that the systemd-networkd wiki page should be littered with his/her particular use of it in container configurations. Id suggest you ignore it, and read the relevant man pages instead.

We can't tell you if DHCP or static is "best" - first of all, "best" is totally subjective, but more importantly, you haven't detailed your requirements, apart from your need to "configure a network connection". Based on that alone, use either.

Where can i Find those man pages? And man pages of what? For example, this: https://wiki.archlinux.org/index.php/Ne … figuration suggests to configure with netctl or dhcpd or systemd-networkd. Maybe i am wrong about this. Should i use netctl and then read man pages of it? I am a bit confused. I wanted to configure with systemd-networkd ( if this is a package ).

On your hard drive or on the internet, see https://wiki.archlinux.org/index.php/Man_page

And man pages of what?

Whatever you want to use, but this thread was about systemd-networkd, so start with `man systemd-networkd`.

Your switch cannot assign you an IP - https://en.wikipedia.org/wiki/Network_switch

Depending how your network is constructed (routers, access points, wifi extenders etc, home made routers), you can go either way - https://wiki.archlinux.org/index.php/Ne … _interface

Sorry for the late reply! Man pages are VERY helpful! I managed to configure a static connection. I am in a room of a building with other students. My building hase three switches and i have a router in my room which is connected to the bulding's 1st switch. I have the right settings now. When my machine boots i have internet some seconds/minutes later. Why is that?

... because you configured your connection correctly. Please ask a better question.

HAHA, I mean it is not connected immediately after boot. And sometimes not connected at all and i have to restart. Better now?

Ok, Here it comes ,

My internet connection is slow. I have a laptop next to me with windows on it and the difference is huge.

I am posting several outputs of commands.

Isn't it supposed to look like this:

Have you tried using netctl?
https://wiki.archlinux.org/index.php/netctl

Follow the instructions there in the configuration section. You just need to find the interface name in you system with "ip link", for example something like enp2s0.

Yes, I have tried no change in my wget time and ping etc.

Is there any way to figure out if my problem is related to my network card driver?

Head_on_a_Stick · 2015-03-09 19:53:51

How does the connection perform if you try it in the live environment with different distributions?

I do not know yet. But I will try this and will post results. But i should mention that, in the same computer, i have been working with various linux distros for the past 7-8 years. Firstly ubuntu, ubuntustudio, fedora and then I installed debian. In the first 3 distributions I had no problems at all with my network connections. In debian I was struggling a lot with configurations. The only solutions that worked were to use dns server from google and install r8168 driver instead of r8169. Also i would like to mention, when I booted with a kernel option --noapic or something like that, internet was really fast. I do not know why. Maybe you could give me an idea.

Anyway, In arch linux I have installed r8168 and seems to be better. Also, I installed namebench and configured my dns servers with 8.8.8.8. No great changes, still after boot my network connection is established after minutes instead of seconds. Is this information helpful?
