Linux Network configuration

One, configure the network

Configuration file:/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0//Device name

HWADDR=00:0C:29:43:95:49//Physical Address

Type=ethernet//Ethernet, NIC type

Onboot=yes//Whether random start

Bootproto=none//Whether to obtain IP automatically

ipaddr=192.168.155.10//IP Address

netmask=255.255.255.0//Subnet mask

gateway=192.168.155.1//Gateway

#DNS1 =192.168.155.1//This do not set, or remote connection, it is always not connected

dns2=8.8.8.8//ping External Network

Remote connection is not up, you can look at:1. Firewall has no off (IPTABLES-NVL)

2.selinux no off (Setenforce 0 off)

If you can't connect, you can set the firewall to allow connections:

Iptables-nvl-i input-p tcp-s 192.168.155.8--dport 22-j ACCEPT
