I am certain there is some way to configure systemd-resolved to actually use internal DNS servers so you can resolve your local hostnames. But nothing I’ve tried have worked, and I don’t actually need this wild local DNS thing.<\/p>\n
Here’s the problem — systemd-resolved creates an \/etc\/resolv.conf file that uses a localhost address as the nameserver — and that may very well forward requests out to Internet DNS servers. Which don’t have any clue about your internal DNS zones — thus you can no longer resolve local hostnames. Whenever I see 127.0.0.53 in \/etc\/resolv.conf, I know systemd-resolved is at work.<\/p>\n
[lisa@linux ~]# cat \/etc\/resolv.conf\r\n# This is \/run\/systemd\/resolve\/stub-resolv.conf managed by man:systemd-resolved(8).\r\n# Do not edit.\r\n#\r\n# This file might be symlinked as \/etc\/resolv.conf. If you're looking at\r\n# \/etc\/resolv.conf and seeing this text, you have followed the symlink.\r\n#\r\n# This is a dynamic resolv.conf file for connecting local clients to the\r\n# internal DNS stub resolver of systemd-resolved. This file lists all\r\n# configured search domains.\r\n#\r\n# Run \"resolvectl status\" to see details about the uplink DNS servers\r\n# currently in use.\r\n#\r\n# Third party programs should typically not access this file directly, but only\r\n# through the symlink at \/etc\/resolv.conf. To manage man:resolv.conf(5) in a\r\n# different way, replace this symlink by a static file or a different symlink.\r\n#\r\n# See man:systemd-resolved.service(8) for details about the supported modes of\r\n# operation for \/etc\/resolv.conf.\r\n\r\nnameserver 127.0.0.53\r\noptions edns0 trust-ad\r\nsearch example.com<\/pre>\nTo disable this local name resolution, stop and disable systemd-resolved, unlink the \/etc\/resolv.conf file it created, and restart NetworkManager<\/p>\n
[lisa@linux ~]# systemctl stop systemd-resolved.service\r\n[lisa@linux ~]# systemctl disable systemd-resolved.service\r\n[lisa@linux ~]# unlink \/etc\/resolv.conf\r\n[lisa@linux ~]# systemctl restart NetworkManager\r\nRemoved \/etc\/systemd\/system\/multi-user.target.wants\/systemd-resolved.service.\r\nRemoved \/etc\/systemd\/system\/dbus-org.freedesktop.resolve1.service.<\/pre>\nVoila, \/etc\/resolv.conf is now populated with reasonable internal DNS servers, and you can resolve local hostnames.<\/p>\n
