Static IP Not Working After System Update

[haroldjclements]

Hello forum,

I have just did a full system update to a fresh install of Arch on the Raspberry Pi. After adding rw at the front of cmdline.txt to get my system out of read-only mode I have another issue. My static IP (using ethernet) now not working and I am not too sure how to get it back. I have tried disabling dhcpcd@eth0 and issuing a netctl start / enable (I have checked my /etc/netctl/eth0 config file). However, this has not worked. I have also noticed that my UK keyboard setting have also been wiped out.

Any idea's of what is causing the lack of network / how to get it back?

Kind Regards,
Harold Clements

Harold, I don't know
dhcpcd@eth0 should never have been there, systemctl disable dhcpcd@eth0

The only thing, if your file in /etc/netctl is right is systemctl enable netctl-auto@eth0
That eth0 does not refer to filename but file(s) where Interface=eth0

I will have to try your suggestion in a couple of hours when I get home.

Yes, It was systemctl disable dhcpcd@eth0 that I issued. However, that was more our of desperation that anything else.

What I don't understand is that it was all working fine until I did the full system update. After this update, the OS was left read-only - I was wondering if this had anything to do with it (as in, if I needed to edit the cmdline.txt to fix the read-only issue, what else has this update trashed?). On that note, I did notice that my UK keyboard has been changed to US!

Kind Regards,

Have you fixed the rw issue?
Simply put rw just before rootwait in cmdline.txt
All other arm devices I have encountered have needed this in the bootargs, rpi this a new thing

Yes, I have fixed the read-only issue (thanking you for the solution).

The systemctl enable netctl-auto@eth0 command created another link, but after a reboot and a start for good measure the problem still exists.

Below is the output from ip addr if that helps?

$this->bbcode_second_pass_code('', '1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default

Woohoo...

Thanks to the following thread (very last post), I have sorted the issue. However, I am not 100% sure what I have actually done! http://www.raspberrypi.org/forums/viewtopic.php?p=414426#p414426

I will outline the basics:

systemctl stop netctl-ifplugd@eth0
systemctl disable netctl-ifplugd@eth0
netctl stop-all
netctl disable eth0
nano /etc/netctl/eth0
Removed the brackets from around the Address field: Address = '192.168.1.10/24''
Add brackets around the Gateway filed: Gateway=('192.168.1.1')
systemctl start netctl@eth0
At this command I get an error.
netctl start eth0
netctl enable eth0
Reboot

$this->bbcode_second_pass_code('', '4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether b8:27:eb:20:8d:c0 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.10/24 brd 192.168.1.255 scope global eth0

')

Thank you once more for your help, it was very much appreciated

Whoops, I put netctl-auto@eth0, I get them two mixed up.
Sorry

No need to apologise, I am just grateful for the help...
