Hello all,
I'm getting frustrated attempting to understand; I googled and asked folks and am unable to get a straight answer.
1. How is the /etc/resolv.conf file maintained ? I do not seem to get a consistent result when I save resolv.conf configuration from GUI or by hand using vim /etc/resolv.conf.
a. Sometimes I the entries toggles between the two entries:
# generated by NetworkManager, do not edit! ; Use a local caching nameserver controlled by NetworkManager nameserver 127.0.0.1
b. then when I restart the network services some the /etc/resolv.conf file appears like this: # generated by NetworkManager, do not edit! ; Use a local caching nameserver controlled by NetworkManager search lab.mycompany.com nameserver 192.168.17.2
This host is:
- a DNS server that is authoritative for its domain within the 192.168.16/20 network - I believe that even as DNS server, this host should have its resolv.conf file configured to define itself as a DNS server, right?
I apologize for the naive questions, but I am a newbie and am unable to gather a straightforward answer.
thanks in advance.
