[solved] No DNS in resolve.conf when IP/DNS is set static

elzear · 6. August 2014

Hello,

I'm new in forum,, and I'd like to say hello
I'm using OMV a while ago, and in last week I have installed Kralizec.
Everything worked perfectly when OMV get IP from DHCP. When I set static IP and /DNS in webgui, resolveconf don't input information in /etc/resolv.conf
I've tried to do:

Code

dpkg-reconfigure resolvconf

But it's don't give me any effects. When I put in file /etc/resolv.conf manually information ex.:

Code

nameserver 8.8.8.8

It's working till next reboot ofc.
I have Realtek network card inside:

Code

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

And I wasn't have installed proprietary firmware for it, so I installed firmware-realtek, bot after reboot it still not working.
Also I notice that, configuration in /etc/network/interfaces is set properly, I mean "dns-nameservers" are there (same as in tab DNS servers in WebGui) when I set static IP, but it is not transferred to /etc/resolv.conf.
When I set DHCP it transfer information to /etc/resolv.conf from my DHCP server (router).

Did you set the settings in the dns server tab?

Yes, I've done it. I rebooted server after changes also.

What is the output of:

Code

cat /etc/openmediavault/config.xml | awk '/<interfaces>/,/<\/interfaces>/'
cat /etc/openmediavault/config.xml | awk '/<dnsnameservers>/,/<\/dnsnameservers>/'

What is the output of:

Code

cat /etc/openmediavault/config.xml | awk '/<interfaces>/,/<\/interfaces>/'
cat /etc/openmediavault/config.xml | awk '/<dnsnameservers>/,/<\/dnsnameservers>/'

FYI
I'm right now using DHCP, not static settings. Should I switch to static settings? At the moment DNS working as expected.

cat /etc/openmediavault/config.xml | awk '/<interfaces>/,/<\/interfaces>/'

ryecoaaron · 6. August 2014

I would need the output when it is set to static ip.

I set static IP + DNS, after that reboot, and:

I assume you are clicking on Apply??

Try as root:

omv-mkconf interfaces
cat /etc/resolv.conf

elzear · 6. August 2014

Yes I've also deleted it and save & apply & reboot. After that set it and reboot... No effects.
omv-mkconf interfaces - done

cat /etc/resolv.conf

Code

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

I know that i can put inside /etc/resolv.conf information about nameserver and set permission to read only, probably it will work, but it isn't a solution

ryecoaaron · 6. August 2014

Put IPv6 on manual and save/apply. Then post:

cat /etc/network/interfaces

elzear · 6. August 2014

cat /etc/network/interfaces

Code

# The loopback network interface
auto lo
iface lo inet loopback
iface lo inet6 loopback


# eth0 network interface
auto eth0
allow-hotplug eth0
iface eth0 inet static
    address 192.168.1.254
    gateway 192.168.1.1
    netmask 255.255.255.0
    post-up /sbin/ifconfig $IFACE mtu 0
    dns-nameservers 192.168.1.1 8.8.8.8
iface eth0 inet6 manual
    pre-down ip -6 addr flush dev eth0

ryecoaaron · 6. August 2014

The following two lines shouldn't be in there. Not sure why they are. Are you adding anything in options?

Code

post-up /sbin/ifconfig $IFACE mtu 0
dns-nameservers 192.168.1.1 8.8.8.8

elzear · 6. August 2014

This is screenshot from configuration.
Should I try to remove those lines?

ryecoaaron · 6. August 2014

You could setting the mtu to 1500 and save/apply. If that doesn't work, I would remove those lines and reboot. Let me know if they come back.

elzear · 6. August 2014

I've change MTU (nothing change), remove those 2 lines and reboot (I leave mtu 1500).
After that... I'm unable to connect by SSH
But Web working, and I've checked DNS, not resolving (tried to update system).
I switch back to DHCP atm, after reboot, SSH/DNS working.

ryecoaaron · 6. August 2014

I guess you will need to post a bug here. I can't duplicate it on my systems.

elzear · 7. August 2014

I finally got it. I don't know why exactly it was needed, but:
In section Network/Interfaces I removed eth0, and rebooted.
After that as I assumed it should be recreated , but interface won't go UP.
So I connected server to monitor and manually set it up and set dhclient:

Code

ifconfig eth0 up
dhclient eth0

At the end I logged on to web interface, and set static IP, and reboot afterwards.
Everything working as need to be expected

and one more thing, as you said there isn't those 2 lines in /etc/network/interface

GNU nano 2.2.6 File: /etc/network/interfaces

Code

# The loopback network interface
auto lo
iface lo inet loopback
iface lo inet6 loopback


# eth0 network interface
auto eth0
allow-hotplug eth0
iface eth0 inet static
    address 192.168.1.254
    gateway 192.168.1.1
    netmask 255.255.255.0
    dns-nameservers 208.67.222.222 8.8.8.8
iface eth0 inet6 manual
    pre-down ip -6 addr flush dev eth0

Thanks for help
btw. I've changed post name, because I cannot add "[solved]" to it, and I thing now it is more clearly

Jetzt mitmachen!
