Ich verstehe nicht, warum ich auf einer Maschine (Debian 9) so viele /etc/resolv.conf.dhclient-new.xxxx-Dateien habe
meine /etc/dhcp/dhclient.conf
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
send host-name = gethostname();
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, domain-search, host-name,
dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
netbios-name-servers, netbios-scope, interface-mtu,
rfc3442-classless-static-routes, ntp-servers;
/etc/network/interfaces
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
auto wlan0
allow-hotplug eth0
iface eth0 inet dhcp
/etc/resolv.conf
#lsattr /etc/resolv.conf
----i---------e---- /etc/resolv.conf
/etc/resolv.conf
unveränderlich machen .sudo chattr -i /etc/resolv.conf
meinen Fall gelöst! Ich bin sehr dankbar!
