WIFI and local DNS
by gsurfdude from LinuxQuestions.org on (#57WQR)
Hello all,
I am fairly experienced with linux administration but I am stumped on this one. I have a CENTOS host with a another CENTOS vm guest. The guest is configured to be my only dns server. It's ip is 192.168.1.108. My laptop which runs fedora 32 and is wireless. Do I need to edit all the wifi connections I have for my home? I have 4. 1 is the 5g, 2. is the 2.4, 3. is a range extender and 4. is DD-WRT set up as a repeater. When I configured the wifi using the 5g for example, my /etc/resolv.conf looks like this
search home.com
nameserver 192.168.1.108
nameserver 8.8.8.8
nameserver 8.8.4.4
But this does not connect me to the Internet using firefox. And, if I ping the name server "centos-dns" the ping returns google ip address rather 192.168.1.108
And while on the fedora laptop I run nslookup 'fedora-ws' (no quotes) it doesn't return the correct PTR records.
All my hard wired machines resolve with the DNS - I have 3 physical machines with each one running 1 vm centos guest machines (database server, web server and subversion). I ssh to any one of these and ping another centos machine, it returns ,my FQDM. But not from the wifi laptop.
What do I need to set up so that wifi uses the local internal dns? I currently set all the host names/ip addresses in /etc/hosts
I hope this make sense.
