Hello.
when netbird agent is connected, the search domain that is added to /etc/resolv.conf is taken from the hostnamectl.
but it configures the full subdomain and ignores anything from the domain itself.
options:
1) only the domain should be added and not only the subdomain
2) use the DOMAIN in the ifcfg configurations
3) append the netbird internal domain to the existing search line in the /etc/resolv.conf and not changing the whole line
for example:
[root@rd04 ~]#hostnamectl
Static hostname: rd04.it.qwilt.com
Icon name: computer-server
Chassis: server
Machine ID: 5686d4f4b0594891a22e2dfdd844b3ae
Boot ID: dcf86e33e95148639087f37fd8460d57
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-862.3.2.el7.x86_64
Architecture: x86-64
[root@rd04 ~]#cat /etc/resolv.conf
Generated by NetBird
If needed you can restore the original file by copying back /etc/resolv.conf.original.netbird
BUT in the ifcfg config file the search domain is being ignored:
cat /etc/sysconfig/network-scripts/ifcfg-enp15s0f0 | grep DOMAIN
DOMAIN=qwilt.com
so any resolve that we use that is hostname.subdomain are being ignored

the only way to resolve this is by changing the hostname to rd14.qwilt.com
then the qwilt.com domain is added and the search works.
