linux查看本机ip的命令是“ifconfig”命令和“ip address”命令；linux查看端口号的命令是“lsof -i:port”命令和“netstat -aptn”命令。

查看本机ip：

1）ifconfig命令

输出如下：

[root@topgun /home/cly]# ifconfigeth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500        inet 192.168.128.132  netmask 255.255.255.0  broadcast 192.168.128.255        inet6 fe80::20c:29ff:fe45:63ba  prefixlen 64  scopeid 0x20<link>        ether 00:0c:29:45:63:ba  txqueuelen 1000  (Ethernet)        RX packets 1936  bytes 2440516 (2.3 MiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 1207  bytes 94802 (92.5 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0        device interrupt 19  base 0x2024  lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 16436        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 0  (Local Loopback)        RX packets 12  bytes 744 (744.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 12  bytes 744 (744.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

该命令属于包：

[root@topgun /home/cly]# pacman -Qo ifconfig/sbin/ifconfig 属于 net-tools 1.60.20120804git-2

2）ip address命令

输出如下：

[root@topgun /home/cly]# ip address1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 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    inet6 ::1/128 scope host        valid_lft forever preferred_lft forever2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000    link/ether 00:0c:29:45:63:ba brd ff:ff:ff:ff:ff:ff    inet 192.168.128.132/24 brd 192.168.128.255 scope global eth0    inet6 fe80::20c:29ff:fe45:63ba/64 scope link        valid_lft forever preferred_lft forever

该命令属于包：

[root@topgun /home/cly]# pacman -Qo ip/usr/sbin/ip 属于 iproute2 3.5.1-1

Linux查看本机端口

查看指定的端口

# lsof -i:port

查看所有端口

# netstat -aptn

安装telnet

#yum install -y telnet.x86_64

#telnet ip 端口
