Ubuntu configuration ETH NIC, fixed IP address

Ubuntu configuration ETH nic, fixed IP address

1, modify the configuration file/etc/network/interfaces [email protected]: ~# sudo gedit/etc/network/interfaces

Add the following: auto eth0 #设置自动启动eth0接口iface eth0 inet static #配置静态IP address 192.168. 11.88 #IP地址netmask 255.255.255.0 #子网掩码Gateway 192.168.11.1 #默认网关

2. Modify DNS sudo gedit/etc/resolve.conf

nameserver 127.0.0.1 #记得加上nameserver 8.8.8.8 #当地dns服务器 (view local DNS with Ipconfig/all, first DNS is default, Total 2 DNS)

Note: #后面的注释信息不要加进去.

3. Restart the network for the configuration to take effect sudo/etc/init.d/networking restart

4. See if IP is configured successfully[email protected]: ~# ifconfig eth0 Link encap:ethernet HWaddr 00:0c:29:2d:89:40 inet Addr:192.168.11.88bcast:192.168.11.255  mask:255.255.255.0           Inet6 Addr: FE80::20C:29FF:FE2D:8940/64 Scope:link           up broadcast RUNNING multicast  mtu:1500  metric:1           RX packets:223 errors : 0 dropped:0 overruns:0 frame:0           TX packets:253 errors:0 dropped : 0 overruns:0 carrier:0           collisions:0 txqueuelen:1000            RX bytes:24219 (24.2 KB)   TX bytes:22960 (22.9 KB)   & nbsp;       interrupt:19 Base address:0x2024

Note: The red word bold "192.168.11.88" is the same as the IP configured above, indicating that the IP configuration was successful.

If your network is not starting or unstable, try the following:

Gedit/etc/networkmanager/networkmanager.conf

Managed=false set into Managed=true

I'm using a virtual machine to bridge the NIC to a fixed IP address that communicates between the local virtual machines
