```shell
logical name是網絡卡的名稱,比如eth0
# 檢查網口,點網口的燈
```shell
[root@localhost ~]
# ethtool -p ens33 20
redhat系的網絡卡配置放在/etc/sysconfig/network-scripts目錄下,下面是乙個網絡卡配置的示例:
[root@localhost ~]
# less /etc/sysconfig/network-scripts/ifcfg-ens33
type=ethernet
proxy_method=none
browser_only=no
bootproto=dhcp
defroute=yes
ipv4_failure_fatal=no
ipv6init=yes
ipv6_autoconf=yes
ipv6_defroute=yes
ipv6_failure_fatal=no
ipv6_addr_gen_mode=stable-privacy
name=ens33
uuid=eceb3be3-d693-426a-86db-d1d593a0388c
device=ens33
onboot=yes
ipv6_privacy=no
debian系的網絡卡配配置存在/etc/network/inte***ces檔案裡面,無論有多少塊網絡卡,統統寫在這乙個檔案裡,下面是乙個網絡卡配置的示例:
auto lo
iface lo inet loopback
# the primary network inte***ce
auto eth0
iface eth0 inet static
address 192.168.0.42
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
# the secondary network inte***ce use dhcp
auto eth1
iface eth1 inet dhcp
檢查路由:
[root@localhost ~]
# netstat -rn
kernel ip routing table
destination gateway genmask flags mss window irtt iface
0.0.0.0 192.168.8.254 0.0.0.0 ug 0 0 0 enp13s0f0
192.168.0.0 192.168.0.1 255.255.255.0 u 0 0 0 enp13s0f2
192.168.8.0 192.168.8.254 255.255.255.0 u 0 0 0 enp13s0f0
刪除預設路由:
route delete -net 0.0.0.0/0 gw 192.168.8.254 enp13s0f0
新增預設路由:
route add -net 0.0.0.0/0 gw 192.168.0.1 enp13s0f2
設定dns
[root@localhost ~]
# less /etc/resolv.conf
# generated by networkmanager
search localdomain
nameserver 192.168.236.2
service networking restart
或者ifdown eth0
ifup eth0
[root@localhost ~]
# systemctl restart networkmanager.service
sudo
mount ./dm7_setup_rh6_64.iso /media/cdrom
sudo
umount /media/cdrom
systemctl status ufw
