Hi,
I just setup CentOS 7 on three boxes to fiddle with it.
1. amandine.sandbox.lan is a headless LAN server
2. bernadette.sandbox.lan is a client desktop
3. raymonde.sandbox.lan is another client desktop
I've setup Dnsmasq on amandine.sandbox.lan. Here's the very basic configuration:
# /etc/dnsmasq.conf domain-needed bogus-priv interface=enp3s1 dhcp-range=192.168.3.100,192.168.3.200,24h local=/sandbox.lan/ domain=sandbox.lan expand-hosts no-resolv # DNS server=192.168.2.1 # Postes fixes dhcp-host=00:1E:C9:43:A7:BF,bernadette,192.168.3.2 dhcp-host=00:1D:09:15:4A:D8,raymonde,192.168.3.3
With this setup as such, I can resolve bernadette from raymonde, and I can also resolve raymonde from bernadette. But when I try to resolve either bernadette or raymonde from the server, I get an unknown hostname. The only way to solve this is to add two corresponding lines to /etc/hosts:
# /etc/hosts 127.0.0.1 localhost.localdomain localhost 192.168.3.1 amandine.sandbox.lan amandine 192.168.3.2 bernadette.sandbox.lan bernadette 192.168.3.3 raymonde.sandbox.lan raymonde
This strikes me as a benign redundancy, which makes me wonder if I'm doing something unorthodox here.
Any suggestions?
Niki
