Green Link stopped working

System version NethServer release 7.6.1810 (final)
Kernel release .10.0-957.27.2.el7.x86_64

I tried to add another red link for added internet bandwidth, but as soon as I configured it, my internal network(green) stopped working even though it shows ‘up’ in the dashboard. No DHCP, no internet on any of the machines that are connected. I tried the scan in diagnostics and got the following:

Interface: enp2s0f0, datalink type: EN10MB (Ethernet)
WARNING: Cannot open MAC/Vendor file /usr/share/arp-scan/ieee-oui.txt: No such file or directory
WARNING: Cannot open MAC/Vendor file /usr/share/arp-scan/ieee-iab.txt: No such file or directory
Starting arp-scan 1.9.2 with 256 hosts (http://www.nta-monitor.com/tools-resources/security-tools/arp-scan/)

0 packets received by filter, 0 packets dropped by kernel
Ending arp-scan 1.9.2: 256 hosts scanned in 2.189 seconds (116.95 hosts/sec). 0 responded

I am hoping I will not have to reinstall everything over again. Its been running like a charm thus far…

What’s the output from:

db networks show

I am unable to ssh into the server. Connection is getting refused.

Am i wrong or… you can access to Server Manager? Cockpit or NethGUI?

NethGUI. I restored an old backup and am good now. Thanks for your replies…

that looks like the same behavior yesterday at me
