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?
yes. programs that run on the box do not know if there is a dns server
running.
I have always configured resolv.conf manually.
I apologize for the naive questions, but I am a newbie and am unable
to gather a straightforward answer.
thanks in advance.
