Hallo zusammen,
Drei Probleme: Beim Aufruf von Internetseiten, muss ich Seiten mehrfach aufrufen, Mailserver (imap) werden erst beim zweiten Versuch erkannt und Mails (Thunderbird) geladen und mein NAS (WDMYCLOUD) wird gar nicht mehr gefunden. Nach Wiki ...

ich@hpkubuntu:~$ cat /etc/resolv.conf # This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8). # Do not edit. # # This file might be symlinked as /etc/resolv.conf. If you're looking at # /etc/resolv.conf and seeing this text, you have followed the symlink. # # This is a dynamic resolv.conf file for connecting local clients to the # internal DNS stub resolver of systemd-resolved. This file lists all # configured search domains. # # Run "resolvectl status" to see details about the uplink DNS servers # currently in use. # # Third party programs should typically not access this file directly, but only # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a # different way, replace this symlink by a static file or a different symlink. # # See man:systemd-resolved.service(8) for details about the supported modes of # operation for /etc/resolv.conf. nameserver 127.0.0.53 options edns0 trust-ad search .
