network configuration setup - dhcp

network configuration setup - dhcp

[Neeraj Pal]

Hi all,

I read the readme but not able to configure the barebox DHCP network.
Tried setting up some environment variables like nameserver,
server.ip, etc but not successful.

I have compiled and executed the barebox binary with or without root
(through sudo) on Ubuntu 20.04 focal LTS

I was thinking to configure manually in the sdcard just like uboot
setup then check for the network but still, this work is in progress.

Could someone please point in the correct direction where I just
configure the DHCP and it will automatically load the network?
So, that I can start using NFS.


thanks,
Neeraj

There is more documentation besides the README. For networking see
https://barebox.org/doc/latest/user/networking.html

The default barebox boot target is to net boot. It'll try to get
a DHCP address and then load some predefined files over TFTP
(If it fails, it'll tell you which ones).

If that didn't work, you'll need to tell more about your setup?
What board are you using barebox on?

Part of the question reads like you are using it while Linux is
running (sandbox) and some other like you'd run it directly as
bootloader. Also what kind of errors do you get, can you copy them here?

Cheers,
Ahmad

Thank you for the documentation. I read them and configured the values
but it is not working, so it may be possible that I am not doing it
correctly.

Thank you for the information. At present, I haven't tried it on any
board as I am using it as Sandbox but I have BeagleBone Black and
Raspberry Pi 3B.

Yes, I am trying to execute it as Sandbox and while executing through
sudo please find the information given below:

sudo ./barebox

Re: network configuration setup - dhcp

[Neeraj Pal]

Sorry missed, Network info:

barebox@Sandbox:/ devinfo eth0
Parent: tap0
Parameters:
  ethaddr: 9e:47:e0:0b:cb:ab (type: MAC)
  gateway: 0.0.0.0 (type: ipv4)
  ipaddr: 0.0.0.0 (type: ipv4)
  linux.bootargs:  (type: string)
  linux.devname:  (type: string)
  mode: dhcp (type: enum) (values: "dhcp", "static", "disabled")
  netmask: 0.0.0.0 (type: ipv4)
  serverip:  (type: string)
barebox@Sandbox:/

After ifup -a

barebox@Sandbox:/ devinfo eth0
Parent: tap0
Parameters:
  ethaddr: 80:81:82:83:84:85 (type: MAC)
  gateway: 172.0.0.1 (type: ipv4)
  ipaddr: 172.0.0.2 (type: ipv4)
  linux.bootargs: ip=172.0.0.2:172.0.0.1:172.0.0.1:255.255.255.0:::
(type: string)
  linux.devname:  (type: string)
  mode: static (type: enum) (values: "dhcp", "static", "disabled")
  netmask: 255.255.255.0 (type: ipv4)
  serverip: 172.0.0.1 (type: string)
barebox@Sandbox:/ ping google.com
ERROR: dns: no nameserver specified in $net.nameserver
T T T T T ping failed: Connection timed out

It seems like it is not able to get the IP from DHCP so I am trying to
set up static, once.

Re: network configuration setup - dhcp

[Neeraj Pal]

Hi,

I successfully configured the networking on sandbox env.
So, below are the steps for anyone in need.

On host (ubuntu)
- ip link show => barebox virtual ethernet device will be listed
- sudo brctl addif virbr0 barebox => I already have virtual br0
"virbr0" for Qemu so I have used that to bridge, else create a new
bridge
- sudo ip link set barebox master virbr0
- sudo dhclient -v barebox

On barebox:
- dhcp eth0

logs are given below:
barebox@Sandbox:/ dhcp eth0
T T eth0: DHCP client bound to address 192.168.122.216
barebox@Sandbox:/ ping google.com
PING google.com (172.217.166.238)
host google.com is alive
barebox@Sandbox:/

Thanks and regards,
Neeraj

That could go into the Documentation to make it easier for future users.
Would you like to submit a patch?

Thanks for the bug reports btw,

Re: network configuration setup - dhcp

[Neeraj Pal]

Hello Ahmad,

Yes, it would be very helpful and straightforward for future users to
set up DHCP networking.
Sure, I will submit a patch to add it in Documentation.

planning to include this as an example under the link:
https://www.barebox.org/doc/latest/user/networking.html#lowlevel-network-device-configuration
as 1.3.1.1. or if you want in other places then please let me know.

Thank you

Kind regards,
Neeraj
