The NTP server on v6 gets the right time, so the time stamp jumped to 3 hou= rs I try to manually get network settings via DHCP: # dhclient enc0 ifconfig: ioctl (SIOCAIFADDR): Invalid argument enc0: not found exiting. # dhclient em0 ifconfig: ioctl (SIOCAIFADDR): File exists em0: not found exiting. Network settings haven't changed since 12.2-STABLE. As a solution to the problem, adding lines to rc.conf and reboot helps: ifconfig_enc0=3D"NOAUTO" ifconfig_ygg0=3D"NOAUTO" How to reproduce the issue. Create a FreeBSD 12.3-STABLE (virtual) machine with more than one network interface that receives network settings. Add lines to rc.conf config: ifconfig_DEFAULT=3D"SYNCDHCP" ifconfig_em0=3D"DHCP" Reboot machine. --=20 You are receiving this mail because: You are the assignee for the bug.=
