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.

resolv.conf question
Hello,
I have a centos 4.6 system acting as a router for my local network. I
obtain my eth0 IP address automatically via DHCP from my ISP, sc.rr.com. If
I add 127.0.0.1 to resolv.conf, it won't save it. I tried adding this to my
dhclient.conf
lease {
option domain-name-servers 127.0.0.1;
}
The above is the only entry in the file.
Don't know it caused it but my system locked up 3

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
TIA

centos 6 - changing resolv.conf by hand gets overwritten by rebooting
given machine with C6 x86_64 (seen on C 6.6 but also before and probably
still present on C6.7) only 1 interface, there is dhcp on this network
(for kickstarting) but the machines have static ip's, and NO
networkmanager installed
contents of resolv.conf
search some.domain.here
nameserver x.x.x.x #dns1
nameserver y.y.y.y #dns2
change resolv.conf to:

Fwd: WpaSupplicant how to
Hi,
I was recently going through the how to located here:
http://wiki.centos.org/HowTos/Laptops/WpaSupplicant
This how-to shows the steps to follow to get a wifi interface working
without using NetworkManager and subsequently how to have wireless working
withouth having a user login.
Anyways, when going through this I was having issues because everything
seemed to work but I was never

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

dhcp + static dns
Hi all,
Not having issues setting this in Ubuntu or Windows but I cannot seem
to add a static DNS or search path without it getting over written
when networks restarts.
The file dhclient.conf seems ignored.
I would like to simply have a fixed DNS and search path added to what
ever was found by the dhcp client.
So I don't think peersdns=no is an option.
Any advice is greatly

NetworkManager frustration...
I would like to use dnsmasq to cache nameserver query results, and I
have set dhcp to prepend the 127.0.0.1 name-server to the list of
nameservers. dnsmasq would then automatically exclude the localhost as a
name server and use all the others from the list provided by dhcp.
But it was too nice to be true, because NetworkManager was there, ready
to mess up anything I try to do, including the

nmcli: unwanted secondary ip-address
Dear Simon,
every second IP-address is unwanted. We restarted? eno4:
nmcli con down eno4; nmcli con up eno4
and the second address vanishes. Then after a few ours, the second ip
address reappears.
This is the config-file of eno2:
# cat ifcfg-eno2
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes

Mail has quit working
Added back the IPV6 to /etc/hosts a couple days ago for grins and giggles.
No longer getting IPV6 errors in logwatch for bind. Everything working.
I think removing my ISP's nameservers from /etc/resolv.conf was the fix.
They have been in there forever so still have my fingers crossed.
Again, many thanks!!

fresh install - resolv.conf error?
Before I submit as a bug, has anyone else encountered -- doing a fresh,
clean install of CentOS-3 results in a resolv.conf with only my
secondary nameserver listed and the search domain.
The install works fine, the eth0 and eth1 (onboard e100's) are detected,
all the right info entered, etc -- typical by the book textmode (not
GUI) install that I'd normally do with RH9/RHEL3. Static

I would like to do that very much, only NetworkManager makes you jump through
burning loops to do so.
With network-scripts, it
