What’s the output of db networks show
?
Did you follow the steps on the manual to Reset Network Configuration?
Another option could be to bring the network interface up and use dhclient
command to get assigned a new IP address by DHCP.

I did indeed exactly those steps yes.
After that the signal-event system-init I had a basic set of NIC’s.
I rebooted, after that two virt NIC’s where added.
Now I have 5 NIC’s, lo, br0, br1, virtbr0 and virtbr1.
br0 192.168.0.134 and br1 192.168.0.136

You can try to disable autostart of the network(s) created by webvirtmgr using virsh
command:
virsh
net-list
net-autostart networkname --disable
exit
Then reboot the server and check if virt* interfaces are not shown with ifconfig
or ip a
commands, and if you regained access to the server.
Another option is to remove the active network(s) created by webvirtmgr:
virsh
net-list
net-destroy networkname
net-undefine networkname
exit
Then restart libvirt:
systemctl restart libvirtd
Can you describe your network layout? Why are both interfaces within the same network range? Output of db networks show
could be useful too.

virsh net-list gave me default and eth0
It was the first time I see my old eth0 back, I am used to see that name on ubuntu.
The description of my network?
Easy, I have a fyber connection 512 mbit, to a router, the router give dhcp.
And thats it. All the system get there ip address from that router or I give them a static.
Both br0 and br1 have static ip.
The server has an AD DS and WebVirtMgr running. Also httpd etc…

In Red Hat Enterprise Linux 7 [thus same in CentOS 7 and NethServer 7], udev supports a number of different naming schemes. The default is to assign fixed names based on firmware, topology, and location information. This has the advantage that the names are fully automatic, fully predictable, that they stay fixed even if hardware is added or removed (no re-enumeration takes place), and that broken hardware can be replaced seamlessly. The disadvantage is that they are sometimes harder to read than the eth0 or wlan0 names traditionally used. For example: enp5s0.
Can you ping any of the two IP addresses or, if httpd-admin service is running, access the server-manager using any of them? (If I recall correctly you use a custom port number for the server-manager, verify it didn’t change).
If not working, you could try to remove one of the bridges:
config show nsdc
db networks delete br1
ifconfig br1 down
brctl delbr br1
rm -f /etc/sysconfig/network-scripts/ifcfg-br1
service network restart
signal-event system-init
/var/log/messages might give some clues on the problem.
@Marc, thx.
No, i can’t ping the NIC’s. The portnumber isn’t changed.
I still can’t ping the address left.
Pit
thinking of reinstall the whole thing.
Did you configure your Nethserver via web UI between reset and reboot? I’d give the network reset another try before reinstalling…
Maybe just try with only one (green) interface…
My network config when having AD and webvirtmgr installed, just to compare:
# db networks show

So, I think it is time to reinstall, isn’t?
Pit
A problem is, the machine is here at home, after full configuration i have to take it to my classroom where i teach. The network sistuation there is totally different so i maybe have the same problems all over again.
Pit
Guess my teaching skills
Pit
it’s not english
When reinstalling I recommend to start with setup local AD because it configures the bridge you may just use in webvirtmgr.
Maths?
You may just setup the Nethserver at home. Then configure a network client (laptop, school pc) to be in your home network by giving it an IP like 192.168.0.222 so you may reach the web UI of Nethserver with that client at school and then being able to configure your Nethserver to work in the school network.
Don’t forget to change IP of the AD container at school too:

IT, specialy Linux
Thx for the info. I worked meanly with Debian likes.
Pit
I think I am going to try and use VirtualBox in the next version of this server.
Pit
Good idea, it’s easier to test things in a VM.
There are some Nethserver school/education projects you may have a look at:
Maybe you could try to configure your interface manually:
db networks set br0 bridge
db networks setprop br0 ipaddr 192.168.0.134
db networks setprop br0 netmask 255.255.255.0
db networks setprop br0 gateway 192.168.0.1
db networks setprop br0 role green
db networks delete enps31f6
db networks set eth0 ethernet
db networks setprop eth0 bridge br0
db networks setprop eth0 role bridged
db networks show
=> output should look similar to @mrmarkuz post
signal-event interface-update
Maybe you have to reboot. Important is “role=green” to be reachable.
I have allready reinstalled the system. Started all over again.
Everything is working fine now.
I want to thank Markus for his great post, I think I will use a lot from that page. Thanks!
Pit
Great to hear everything is working again.
Please mark the topic as solved then.
Have a great time with Nethserver!
Very nice and clear explination.
Thank You
