thanks much for replies ... so to be clear:
qatest1 - 192.168.17.1 (DHCP server)
qatest2 - 192.168.17.2 (DNS server)
- both have STATIC-assigned IP address.
1. So I SHOULD leave the DNS entries in /etc/resolv.conf (whether GUI
or not) - blank in the DNS server - qatest2? I tried to configure it
via the GUI this time with:
hostname - qatest2
Primary DNS - 192.168.17.2 # which is its own IP address
Search - lab.mycompany.com
After restarting, when I cat /etc/resolv.conf it refers to its loopback address:
# generated by NetworkManager, do not edit!
; Use a local caching nameserver controlled by NetworkManager
search lab.mycompany.com
nameserver 127.0.0.1
2. In the meantime, I configured qatest1 - the DHPC server belonging
within qatest2's DNS domain, with the following in Network Manager
GUI:
hostname - qatest1
Primary DNS - 192.168.17.2 (which is the DNS server's IP)
searchpath - lab.mycompany.com
upon restart its /etc/resolv.conf file seems to be correct:
# generated by NetworkManager, do not edit!
; Use a local caching nameserver controlled by NetworkManager
search lab.mycompany.com
nameserver 192.168.17.2
Should I leave my DNS server's /etc/resolv.conf file entries blank?
Thanks in advance,
