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.
