simple DNS question - reverse nslookup fails.
Hello all,
I am trying to configure a subdomain DNS server on a Cent OS 5.1 - for
my lab. Brief configuration:
Lab machine ---> 192.168.17.2 (should respond to DNS queries from
hosts in 192.168.16.0/20 network)
1. I would also like to forward any queries outside the above network
to our corporate domain (no firewalls between our 192.168.16.x network
and the corporate network. The domain

NetworkManager and /etc/resolv.conf
CentOS 7.5 image running on linode.
unbound running on localhost.
Have to use a cron job once a minute to keep /etc/resolv.conf using the
localhost for name resolution - whenever NetworkManager gets restarted
(usually only a system boot) it gets over-written.
It seems every distro has a different way of preventing NetworkManager
from replacing that file.
I found instructions for Fedora that

NetworkManager constantly overwriting /etc/resolve.conf - how to disable?
Hi all,
I have a CentOS 5.4 server-only installation, i.e. no X installed, and
for some odd reason /etc/resolve.conf gets overwritten by
NetworkManager on a constant basis. I haven't been able to track down
how often, but I think it's on the hour, or something.
This is the conents of the file right now:

Who deletes/edits my resolv.com ?
Every now and again the nameservers in /etc/resolv.conf
on my CentOS-6.5 server are commented out.
I used to think this was the fault of NetworkManager,
but I've stopped running that on the server
(using the network service instead)
and the nameserver removal still occurs.
I'm baffled by the motivation for this,
as I can't think of any situation
where it would be of advantage to have

Unable to edit resolv.conf
Hello,
I changed ISPs and need to update name servers in resolv.conf.
I have tried nano, gedit, Webmin, system-config-network and it won't allow
me to make the changes.
I have Network Manager turned off and when I enable it , eth0 and eth1 have
no entries.
I enabled it, added the connections, but still no changes.
I'm stuck

DNS in CentOS
Hello,
Am running Bind 9 in Cent OS 5.1. I have a DNS server, that:
- DNS server to hosts in lab.company.com - 192.168.17.x
- forwards query to company.com - 10.100.x.x.
Problem:
1. FQDN and by-IP-address ping and nslookup is successful.
2. ping/nslookup by host-name-only --- from any 192.168.17.x hosts to
any 10.100.x.x hosts fail and vice versa.
I have setup the DNS of lab.company.com

Network Manager / CentOS 7 / local unbound
Hello list -
http://unix.stackexchange.com/questions/90035/how-to-set-dns-resolver-in-fedora-using-network-manager
That says it works for CentOS 5 and I *suspect* the methods there (3
listed) would work, but what is the best way with NetworkManager to set
it up to use the localhost for DNS ?
I'm paranoid about DNS spoofing and really prefer to have a local
instance of DNSSEC enforcing

I would like to do that very much, only NetworkManager makes you jump through
burning loops to do so.

One DC cannot authenticate off of another DC
Thank you, Louis, for your reply.
By simply asking me to provide outputs of the aforementioned files, I found the cause of my first problem (auth failing). It was my /etc/hosts file on dc1.
All of them should look like this, and indeed DC2 and DC3's *did* look like this:
# cat /etc/hosts
> 127.0.0.1 ? ? ? localhost.samdom.mycompany.net ?localhost

resolv.conf rewritten every reboot. How to figure out who and why?
My machine has a static IP, with dhcp and IPv6 disabled. Every time I
reboot, some process rewrites /etc/resolv.conf, including a comment
about dhcpclient. The only package I have installed that shows up in
"rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in
there is named dhcpclient.
I'd like to figure out what software is rewriting this file and why.

From network-scripts to NetworkManager on a router : questions
Hi,
I'm running CentOS 7 on all my servers, in three different contexts :
1. simple local server
2. public facing server
3. router/gateway/firewall
I'm currently in the process of moving my KISS-style
network-scripts-style configurations to something more orthodox based on
NetworkManager.
Scenarios (1) and (2) caused no problems, but (3) is giving me some
