[arch-general] manually configure network
I've just changed ISP and I can't get the changed configuration to stick. I'm using 'static IP address - manual assignment' from Network configuration wiki page. I need to change my address from 192.168.1.0/24 to 192.168.20.1/24. using iproute2 tools as per wiki I can get everything working UNTIL I reboot, at which time some of the settings show the old values and others the new. I've been manually configuring these settings without problems since I started using linux in 1994.

I assume that (as well as changing ISPs) you have changed your router and it has a different internal range to the old one. If you have an IP address automatically after booting then something is bringing up the network automatically. Assuming your Arch install is newer than 2013 then I would expect you've configured netctl to manage the interface. Look in /etc/netctl and $ systemctl list-unit-files --state=enabled --- mrrob ---

Correct

About april 2013 , can't remember details of what I did then but I would have used what was most like the the original method.

You are probably using dhcpcd. This is what is installed when initially setting up the OS. Depending on exactly what settings are being reverted to default it may be normal behavior. What you need to do is find out exactly which network manager you are using and exactly what settings are not sticking across a reboot. The fix is probably not difficult but need more info to be able to make intelligent suggestions. I had a problem with dhcpcd reverting my DNS servers to the ISP defaults on every restart. --Rich

I tried it when I first started with linux in 1994 and now avoid it like the plague, I'd rather do it manually. It was simple until somebody decided I need a string of cascading daemons to do everything. mick stressed out and frustrated in frozen glen innes

There was a simple elegance in rc.conf, e.g.: interface=eth0 address=192.168.1.17 netmask=255.255.255.0 broadcast=192.168.1.255 gateway=192.168.1.11 But with netctl, (https://wiki.archlinux.org/index.php/Netctl) it's not that much different. Instead of rc.conf, find your network interface with `ip addr` (enp0s10 below), create a profile in /etc/netctl (say /etc/netctl/mystaticip). You can pull an example of a static setup from /etc/netctl/examples. A minimal example (for ipv4) a static IP is something like: Description='A basic static ethernet connection' Interface=enp0s10 Connection=ethernet IP=static Address=('192.168.1.16/24') #Routes=('192.168.0.0/24 via 192.168.1.2') ## I don't use Gateway='192.168.1.13' DNS=('192.168.1.16') Then (after testing with e.g. 'netctl start mystaticip'), all you need to do to have it set each time you boot is issue the command # netctl enable mystaticip which will essentially create the hook required to activate your connection in /etc/systemd/system. Hopefully that will relieve some stress and frustration. -- David C. Rankin, J.D.,P.E.

Correct, and the ISP failed to include modem password in the box.

thank you, I now can make sense of most of what to do. DNS isn't working if I try to go through the new modem but that is an issue with the ISP and configuring the modem once I get the password for the account. On 13 July 2017 at 03:43, Rich <rich-mail@octoxol.com> wrote:

_They_ announced the change from netcfg to netctl on the 10th of April 2013. This isn't entirely relevant to the problem but may give insight into how you originally set it up. [0] If you want you can look at the old versions of the wiki page for netcfg. It looks like systemd-networkd.service is responsible [1]. I suggest you look to reconfigure that perhaps by looking for foo.network configs in /etc/systemd/network/ or using networkctl.
