I can't update an IP address from DHCP to static. I changed the /etc/network/interfaces file and I rebooted the system but IP still is the same as the one that DHCP gave me before.

I changed /etc/network/interfaces to:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.205
netmask 255.255.255.0
gateway 192.168.1.1

I got this error in syslog when I executed /etc/init.d/networking restart:

uname -a gives:

And /etc/os-release contains:

I tried to execute the script /sbin/ifup, result:

root@raspberrypi:/sbin# ./ifup  -a
/etc/network/if-pre-up.d/iptables: 2: /etc/network/if-pre-up.d/iptables: /sbin/iptable-restore: not found

./ifup: pre-ifup script failed.

If you are really determined to do it this way you need to disable the DHCP client daemon and switch to standard Debian networking:

sudo systemctl disable dhcpcd
sudo systemctl enable networking

    @Miren the comments are illegible. Paste any code into your question. From the look of it you are running as root. This is not normal for Raspbian, and requires system changes. Most advice will assume you are running as a normal user on an unmodified system. If you are not you need to clarify exactly what you have done. – Milliways Sep 01 '16 at 00:22

Looks like the way we set the static ip has changed. There is a post here in the link which talks about static ip. Please look at the answer from steve(Answer 2).

Raspberry seems to ignore static ip setting

Refer the post: Connecting Raspberry Pi (running Raspbian) to open WiFi using only the command line for more details.

  • I still have the same problem. IP address doesnt update. – Miren Aug 30 '16 at 09:38
  • Have you actually tried this before giving others advice. Unless you disable dhcpcd it will still attempt to allocate addresses. – Milliways Aug 30 '16 at 09:59
  • @Milliways Yeah I have tried it on my debian system but not on my raspberry pi. I have a Ubuntu 12.04 in which I have set static ip for some testing purpose. I will be accessing my Rpi once I reach home and I don't have access now. I will give detailed steps once I set it up on my Raspberry pi. I will delete the answer if this is not allowing to set it up in my raspberry pi. Also what you mentioned is a striking point we have to disable the dhcpd service to pick up the static ip. – Varad A G Aug 30 '16 at 12:34
  • It probably works on Ubuntu (although I have not tried on 16.04 - but then I spend most of my time trying to convince people NOT to use static) and does work on Wheezy and you can configure Jessie to use the traditional Debian networking. For better or worse (I see improved performance) the Foundation uses dhcpcd by default. Ubuntu (at least current releases) uses Network Manager. Either works, but they are not the only way. See How do I set up networking/WiFi/Static IP for the Raspbian approach. – Milliways Aug 30 '16 at 12:43
  • @Milliways I tried this out in my Raspberry pi and this configuration works for me. I am pasting my "interfaces" file by editing the answer. – Varad A G Aug 30 '16 at 16:28
  • The reason it works is because you call dhcp in /etc/network/interfaces. dhcpcd detects this and deactivates itself, as you would see from boot messages. The original you posted, and that posted by the OP would not work. Incidentally your file is strange - it calls wpa_supplicant, but also includes wpa-ssid - not a good example for others. I suspect it is ignoring wpa_supplicant because you don't use manual. – Milliways Aug 30 '16 at 23:53
  • @Milliways It would begreat if you can please go ahead and edit the post. Then it would be easy for some one to refer it in future. – Varad A G Aug 31 '16 at 00:30
  • If you are suggesting I edit your post, I normally refrain from editing other peoples's posts (except for formatting) or to add a note indicating obsolete information. I do not know what you would want me to say.

    I have already posted a detailed tutorial covering Raspbian Jessie, and normally refer people to this. This includes information for those who want to use standard Debian networking. Earlier posts e.g. http://raspberrypi.stackexchange.com/a/26927/8697 address standard Debian networking

  • I still have the same problem....Allocate IP is the same that DHCP server gave me. root@raspberrypi:/home/pi# sudo service dhcpd status ● dhcpd.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) – Miren Aug 31 '16 at 06:30
  • @Miren can you please update the question with your /etc/network/interfaces , uname -a and /etc/os-release. – Varad A G Aug 31 '16 at 06:51

The best soluition that I have come across is this one. Solved my requirement for static addresses for both eth0 and wlan0 on my Rpi3

dhcpcd vs /etc/network/interfaces

good luck, ianm

You can edit the dhcpd.conf file to set a static ip in Raspbian Jessie. This is how I changed mine.

sudo nano /etc/dhcpcd.conf

Go to the end of the file and edit the following based on your needs.

    interface eth0

    static ip_address=192.168.1.200/24
    static routers=192.168.1.1
    static domain_name_servers=192.168.1.1

    interface wlan0

    static ip_address=192.168.1.200/24
    static routers=192.168.1.1
    static domain_name_servers=192.168.1.1
