linux 测试网络url命令

1.curl 地址或者 wget url地址

[hxxxx@iZ23vy2msooZ ~]$ curl www.baidu.com

wget + 空格 + 要下载文件的url路径

[hxxxx@iZ23vy2msooZ ~]$ wget www.baidu.com

2.ping ip地址 ctrl+c退出 ping只是测试网络联接状况以及信息包发送和接收状况。

[hxxxx@iZ23vy2msooZ ~]$ ping www.baidu.com
PING www.a.shifen.com (220.181.111.188) 56(84) bytes of data.

3.telnet ip地址端口地址

[hxxxx@iZ23vy2msooZ ~]$ telnet www.baidu.com 80
Trying 220.181.112.244...
Connected to www.baidu.com.
Escape character is '^]'.
^C

[hxxxx@iZ23vy2msooZ ~]$ telnet www.baidu.com 443

4.可以使用traceroute命令显示数据包到达目的主机所经过的路由。

[hxxxx@iZ23vy2msooZ ~]$ traceroute www.baidu.com
traceroute to www.baidu.com (220.181.111.188), 30 hops max, 60 byte packets
1 * * *
2 11.240.157.150 (11.240.157.150) 4.258 ms 11.240.144.214 (11.240.144.214) 1.127 ms 11.240.163.246 (11.240.163.246) 4.312 ms

5.可以使用ifconfig命令来配置并查看网络接口的配置情况。

[huangjing@iZ23vy2msooZ ~]$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:3E:01:02:33
inet addr:10.45.54.21 Bcast:10.45.55.255 Mask:255.255.252.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:343207526 errors:0 dropped:0 overruns:0 frame:0

lo Link encap:Local Loopback

TX packets:123 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:7975 (7.7 KiB) TX bytes:7975 (7.7 KiB)

6.显示TCP/UDP传输协议的连接状态

[hxxxx@iZ23vy2msooZ ~]$ netstat -u netstat -t
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

[hxxxx@iZ23vy2msooZ ~]$ netstat -an | grep 7064
tcp 0 0 0.0.0.0:7064 0.0.0.0:* LISTEN
tcp 0 0 10.45.54.21:7064 100.97.54.29:6688 ESTABLISHED
