安裝brctlpython
apt-get install bridge-utils
設置網橋linux
可編輯 /etc/network/interface
文件。不過,我建議在 /etc/network/interface.d/
目錄下放置一個全新的配置。在 Debian Linux 配置網橋的過程以下:網絡
步驟 1 - 找出物理接口編輯器
$ ip -f inet a s
輸出以下:oop
eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 inet 192.168.2.23/24 brd 192.168.2.255 scope global eno1 valid_lft forever preferred_lft forever
eno1是物理網卡rest
更新 /etc/network/interfaces 文件code
確保只有 lo
(loopback 在 /etc/network/interface
中處於活動狀態)。(LCTT 譯註:loopback 指本地環回接口,也稱爲回送地址)刪除與 eno1
相關的任何配置。orm
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback
在 /etc/network/interfaces.d/br0 中配置網橋(br0)server
使用文本編輯器建立一個文本文件,好比 vi 命令:blog
$ sudo vi /etc/network/interfaces.d/br0
在其中添加配置:
## static ip config file for br0 ## auto br0 iface br0 inet static address 192.168.2.23 broadcast 192.168.2.255 netmask 255.255.255.0 gateway 192.168.2.254 # If the resolvconf package is installed, you should not edit # the resolv.conf configuration file manually. Set name server here #dns-nameservers 192.168.2.254 # If you have muliple interfaces such as eth0 and eth1 # bridge_ports eth0 eth1 bridge_ports eno1 bridge_stp off # disable Spanning Tree Protocol bridge_waitport 0 # no delay before a port becomes available bridge_fd 0 # no forwarding delay
若想DHCP 來得到 IP 地址
## DHCP ip config file for br0 ## auto br0 # Bridge setup iface br0 inet dhcp bridge_ports eno1
保存並關閉文件
在從新啓動網絡服務以前,請確保防火牆已關閉。防火牆可能會引用較老的接口,例如 eno1
。一旦服務從新啓動,你必須更新 br0
接口的防火牆規則。鍵入如下命令從新啓動防火牆:
$ sudo systemctl restart network-manager
確認服務已經從新啓動:
$ systemctl status network-manager
藉助 ip 命令尋找新的 br0
接口和路由表:
$ ip a s
$ ip r
$ ping -c 2 cyberciti.biz
示例輸出:
brctl 命令查看網橋有關信息:
brctl show
顯示當前網橋:
$ bridge link
