Hi all,

I am working with a sabresd platform and the following interfaces file

root@imx6qsabresd:~/# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# Wireless interfaces
iface wlan0 inet dhcp
        wireless_mode managed
        wireless_essid any
        wpa-driver wext
        wpa-conf /etc/wpa_supplicant.conf

iface atml0 inet dhcp

# Wired or wireless interfaces
auto eth0
iface eth0 inet static
        address 192.168.0.30
        netmask 255.255.255.0
        gateway 192.168.0.1

iface eth1 inet dhcp

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
iface usb0 inet static
        address 192.168.7.2
        netmask 255.255.255.0
        network 192.168.7.0
        gateway 192.168.7.1

# Bluetooth networking
iface bnep0 inet dhcp

After boot, this is what I can see with ifconfig eth0 command:
NO static ip is set on eth0 for inet

eth0      Link encap:Ethernet  HWaddr 00:04:9F:03:9F:FD
          inet6 addr: fe80::204:9fff:fe03:9ffd/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:19 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:4642 (4.5 KiB)

However, if I execute:
/etc/init.d/networking restart
everything seems to work and I can connect to static ip

Any suggestion will be very appreciated.
Thank you in advance

Alvaro

it seems like /etc/init.d/networking is not executed at boot or
executed when bad timing.

Sorry for I am a newbie with little experience in linux, and may ask for obvious solutions ....How can I know whether it is executed or not and when it is executed?Regards,alvaro

scripts in /etc/init.d/ often get executed by sysV init or upstart daemon.
check /etc/rc2.d for sysV and /etc/init/ for upstart.

you may want edit your networking script to touch file in /tmp when it
get executed to see is it had been executed or not.

I experienced a similar timing problems some time ago, but with udhcpc, and I 
think this presented before:
https://lists.yoctoproject.org/pipermail/poky/2011-August/006931.html

So suggestion is to try waiting when the eth0 link is UP. I think there aren't 
obvious solutions to this, but there are several options you can try.

Bests,
Diego

Since you say you're new to Linux, the following might be helpful to 
know in debugging your init scripts:


You can add a "set -x"  to the top of your networking script to see what 
it's doing and how it's evaluating the conditional logic in the script ( 
don't actually include the quotes ).

Add some additional echo statements in your scripts to help you figure 
out what's going on.   You can also do the same with other scripts in 
the init.d directory.

You're probably booting up at runlevel 5 ( see inittab ).  You can see 
the order of your initscripts booting by looking in the /etc/rc5.d 
directory.  You can also play around with the ordering of initialization 
by changing the prefix number of the file names ( they are symbolic 
links back to the /etc/init.d directory.

Re: static ip

[Hiromichi Matsumura]

I have get the same experience before.

I'm working with SABRElite made by boundary devices inc..
Sorry there may be some differences in between two environments.

There are two network services executing on SABRELite
The one service is Linux network service(/etc/init.d/networking).
The another service is connman (/etc/init.d/connman).

First, static ip was set by Linux network service.
And then, ip address override by connman service.
So, static ip was invalidated by connman.

connman required mac address for setting up the static ip.

I'd like to set ip address in simple way.
So, I removed connman service from init.d .

I will be happy if I can be of any help.

Thanks,
Hiromichi
