Problems with ip static debian 8

[Dan81]

The connection of my neetbook works fine in dhcp but when I change the file /etc/network/interfaces doesn't have connection

[TonyT]

1. change it to what? did you restart the networking service after making changes?
# iface ethx inet static
# address 192.168.x.x
# netmask 255.255.255.0
# gateway 192.168.x.x

2. is Network Manager managing the interface?

[Dan81]

I change the file interfaces like this

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.140
netmask 255.255.255.0
gateway 192.168.1.1

Then I reboot and eth0 is down

[Dan81]

I restart the network with /etc/init.d/networking restart and it says ok.

The NetworkManager is disabled

What I have to do now?

[bw123]

It's okay, there are a lot of threads and wiki pages, plus a pretty long man page for 'interfaces'

Code: Select all

$ man interfaces

What I have to do now?

ifup the interface and see if it works. it should say already up?

https://wiki.debian.org/NetworkConfiguration

this one is good

Use sudo ifconfig to see your interfaces. Who knows, your adapter may be eth1.

[Dan81]

ifconfig shows lo, eth0 and wlan0. If I config the network with ifconfig it runs ok but when reboot only have lo up. If I undo all of the interfaces file it runs ok. What I have to do now?

Why is NetworkManager disabled?

Personally, I found it to be much more reliable than the if* utilities. The only bright spot of systemd.
I actually kind of miss it.

I think you need the line of "allow-hotplug eth0" as well.

Is better to enable NM with static ip?

'ifup -a' says:

'run-parts: failed to exec /etc/network/if-pre-up.d/iptables: Exec format error
run-parts: /etc/network/if-pre-up.d/iptables exited with return code 1
ifup: pre-up script failed'

The iptables have one warning:
'insserv: warning: script: 'firewall' missing LSB TAGS and overrides'

Is that the problem?
