I only have ifcfg-lo , which I am pretty sure is the loopback interface.
As expected, other files suggest eth0 is my ethernet connection.
Should I add a one-line ifcfg-eth0 file?
If you are using ethernet (and not a wireless device or some other
internet connectivity) you should have an ifcfg- file for the
interface. Look at the output of 'ip link' to see all the interfaces
you have configured.
[root@localhost ~]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether 00:23:7d:4d:98:89 brd ff:ff:ff:ff:ff:ff
[root@localhost ~]#
Currently I have
# Generated by NetworkManager
# search midcoip.net
nameserver 2001:48f8:3004:2ce:5a19:f8ff:fe9e:a4bc
nameserver 192.168.0.1
Since there's no ifcfg file, I suspect you're using NetworkManager to
manage your network. ...
I'm using the default I got when I installed centos 7.
Was not aware of any alternatives.
... Run 'nmcli con' to get a list of your network
[root@localhost ~]# nmcli con
NAME UUID TYPE DEVICE
Wired connection 1 e4c3a05e-5f33-3ae8-af71-31b70ecf040b ethernet enp0s25
[root@localhost ~]#
connections, and then run 'nmcli con edit "Connection Name"' (replace
"Connection Name" with the name of your ethernet connection). You can
then set ipv4.ignore-auto-dns to 'yes' and then set ipv4.dns and
ipv4.dns-search. This should override what DHCP sets.
[root@localhost ~]# nmcli con edit enp0s25
Error: Unknown connection 'enp0s25'.
[root@localhost ~]# nmcli con edit eth0
Error: Unknown connection 'eth0'.
[root@localhost ~]# nmcli con edit enp0s25
Error: Unknown connection 'enp0s25'.
[root@localhost ~]#
The last was a copy and paste.
Would I still get leases from DHCP?
Does DHCP set nameservers?
Ideally, I'd like to override just search.
This is documented in /usr/share/doc/initscripts-*/sysconfig.txt
I have /usr/share/doc/initscripts-9.49.47/sysconfig.txt only.
I used the * as a glob, not a literal character.
Sorry about that.
I'd thought you meant that there was a whole set of them.
