Linux Network Configuration

直接用ifconfig配置

设置网卡eth0IP地址和子网掩码
sudo ifconfig eth0 192.168.2.106 netmask 255.255.255.0
设置网关
sudo route add default gw 192.168.2.254
配置DNS
sudo vim /etc/resolv.conf

Gentoo 网络配置文件

sudo vim /etc/conf.d/net
# 我的网卡名叫 enp2s1

# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /usr/share/doc/openrc*/net.example* and save your configuration
# in /etc/conf.d/net (this file :]!).

# DHCP 方式
config_enp2s1=("dhcp")

# 静态 IP
config_enp2s1=("192.168.1.100 netmask 255.255.255.0 brd 192.168.1.255")
routes_enp2s1=("default via 192.168.1.1")   # 设置默认路由(网关)
dns_servers="8.8.8.8"
dns_search="the.dnsdomain.to.search"        # 设置 dns 默认搜索域

#配置多个路由:
routes_enp2s1=(
    "192.0.0.0/8 via 192.0.0.1"
    "default via 192.168.1.1"
)

详细配置参考: /usr/share/doc/openrc*/net.example*

Ubuntu 网络配置文件

sudo vim /etc/network/interfaces

DHCP连接
auto eth0
iface eth0 inet dhcp

手动配置静态ip
auto eth0
iface eth0 inet static
address 192.169.2.106
gateway 192.168.2.254
netmask 255.255.255.0
#network ?.?.?.?
#broadcast ?.?.?.?

# dns设置
# 我印象中重启后resolv.conf的内容会删除
# 所以DNS服务器的配置也是在/etc/network/interfaces下
dns-nameservers 8.8.8.8
dns-search xxx.xxx.xxx...

# 添加一条静态路由
up route add -net 192.0.0.0/8 gw 192.0.0.1 dev eth0
