used for a request, there is no order, the diesgn is to
configure equal namservers and not some with different results

[root@srv-rhsoft:~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=dhcp
IPV6INIT=no
NM_CONTROLLED=no
USERCTL=no
PEERDNS=no

   The instruction I had said to set it here and I did that earlier.

       [root@box7 bobg]# cat /etc/sysconfig/network
       NETWORKING=yes
       HOSTNAME=box7
       NTPSERVERARGS=iburst
       PEERDNS=no

   Now I have changed it here:

           [bobg@box7 ~]$ cat /etc/sysconfig/network-scripts/ifcfg-em1
           UUID="ef05f66e-b998-4218-9bdf-30228be529ce"
           NM_CONTROLLED="yes"
           BOOTPROTO="dhcp"
           DEVICE="em1"
           ONBOOT="yes"
           HWADDR=00:21:9B:78:63:B1
           TYPE=Ethernet
           DEFROUTE=yes
           PEERDNS=no
           PEERROUTES=yes
           IPV4_FAILURE_FATAL=no
           IPV6INIT=no
           NAME="System em1-DHCP"

       "and NO it is NOT ok to have ANY unrelieable DNS in
resolv.conf" I don't think I have any control over that. Viasat wont let me choose a dns. If I do it is "blocked!" In the past I used opendns, [a paid subscription.]

       Well that doesn't work, I can't send!

           [bobg@box7 ~]$ cat /etc/resolv.conf
           # Generated by NetworkManager


           # No nameservers found; try putting DNS servers into your
           # ifcfg files in /etc/sysconfig/network-scripts like so:
           #
           # DNS1=xxx.xxx.xxx.xxx
           # DNS2=xxx.xxx.xxx.xxx
           # DOMAIN=lab.foo.com bar.foo.com

   **    Changed PEERDNS=no back to PEERDNS=yes

** and then I could send ...
