Linux-TCP-IP-Network-Configuration-Files


Linux TCP/IP Network Configuration Files:

/etc/resolve.conf

	List DNS servers for internet domain name resolution.

/etc/hosts

	Lists hosts to be resolved locally (not by DNS).

/etc/nsswitch.conf

	List order of host name search. Typically look at local files, then NIS server, then DNS server.

Example.

[root@fedora ~]# hostname -f
fedora.example.com

[root@fedora ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=fedora.example.com
NTPSERVERARGS=iburst

[root@fedora ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 8.8.8.8

[root@fedora ~]# grep dns /etc/nsswitch.conf
#	dns			Use DNS (Domain Name Service)
#hosts:     db files nisplus nis dns
hosts:      files dns myhostname
[root@fedora ~]#
