Today I couldn’t login to Nextcloud service, so I checked our Nethserver and found
‘kernel: IPv4: martian source 172.16.1.3 from 172.16.1.2, on dev bond0
kernel: ll header: 00000000: ff ff ff ff ff ff 00 1e 67 11 73 71 08 06 …g.sq…’
in /var/log/messages.
172.16.1.3 is the NSDC interface and 172.16.1.2 is the main bonded interface.
I tried to restart the nsdc service but it failed.
In the same logs I found:
'Failed to start NethServer Domain Controller container.`
The server was working well on Friday… Can you help me to investigate further if it’s a hardware problem or a problem with the virtual machine that holds the NSDC?
NethServer as been rebooted from friday to today?
Did kernel version changed?
Which is the output of uname -r ?
Were changed something about ip address or Subnet?
Is 172.16.1.3 address available currently?
