此篇紀錄在 CentOS 6 中所常用的幾個工具將被淘汰,並且替代的工具
ifconfig 替換為 ip addr
#同ifconfig
$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:22:4d:80:7f:6a brd ff:ff:ff:ff:ff:ff
inet 192.168.10.10/24 brd 222.186.42.255 scope global enp1s0
valid_lft forever preferred_lft forever
inet6 fe80::222:4dff:fe80:7f6a/64 scope link
valid_lft forever preferred_lft forever
#查看介面傳輸狀態 -s 詳細
$ ip -s link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
RX: bytes packets errors dropped overrun mcast

2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether 00:22:4d:80:7f:6a brd ff:ff:ff:ff:ff:ff

netstat 替換為 ss
#同 netstat -tunpl
$ ss -tunpl
#檢視tcp連線
$ ss -t
#檢視udp
$ ss -u
traceroute/traceroute6 替換為 tracepath
$ tracepath 8.8.8.8
route 替換為 ip route
$ ip route
192.168.10.0/24 dev eth0 proto kernel scope link src 192.168.121.10
169.254.0.0/16 dev eth0 scope link metric 1003
default via 192.168.10.254 dev eth0
arp 替換為 ip neighbor
$ ip neighbor
192.168.10.108 dev eth0 lladdr e0:ac:cb:66:2a:3c STALE
192.168.10.254 dev eth0 lladdr 10:7b:ef:47:ce:53 REACHABLE
在 CentOS 7 被淘汰的工具只是不在預設安裝所包含的,所以是可以利用 yum 把他安裝回來
Note:在 yum 中不知道套件的名稱,可以用 provides 和 list 直接搜尋 package 裡面的工具
$ yum provides */ifconfig
net-tools-1.60-110.el6_2.x86_64 : Basic networking tools
Repo : base
Matched from:
Filename : /sbin/ifconfig
Orignal From: 在 CentOS 7 中所不見的命令 - Round 1: ifconfig、route、netstat、traceroute
