dhcpcd static IP error...

[SamPhoenix]

I have been using my pi as a homeassistant hub and assigned it a static ip address... It had been working fine for a while and a few days ago it stopped connecting to the network. Upon restarting it, I saw that the it said that dhcpcd.service failed to start so I look into it and find:

Code: Select all

Not running dhcpcd becsuse /etc/network/interfaces defines some interfaces that will use a DHCP client or static address

I have no idea how to fix this... Any help would be appreciated.

Post the contents of your /etc/network/interfaces file.

[SamPhoenix]

Code: Select all

auto lo

iface lo inet loopback

iface eth0 inet static
 address 192.168.0.4
 netmask 255.255.255.0
 gateway 192.168.0.1
 dns-nameservers 8.8.8.8 8.8.4.4
 
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant.conf
iface default inet dhcp

If you are using the Stretch version of Raspbian, remove all that. There should be only one uncommented line in /etc/network/interfaces unless you are setting up a bridge, which you aren't.

I am, so what should I do to keep the static IP but have it actually working?

[SurferTim]

If you are using Stretch, open /etc/dhcpcd.conf with a text editor. There are plenty of commented out examples there.

[SamPhoenix]

But I'm confused about what you told me to remove and keep and what needs to be added.

The current version of /etc/network/interfaces contains the following lines only:

Code: Select all

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

If you want to set a static IP on an interface, do what it says and

consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

or ask here with details of what you want to set and we'll tell you what you need to put in /etc/dhcpcd.conf

Or there are always the excellent learning resources that are available on the pi web site

as per my opinion you reinstall and update your system
