ping

仅限 80 端口,命令中无法指定端口:

C:\Users\Administrator>ping kikakika.com 遗失对主机的连接。 正在 Ping kikakika.com [111.231.221.219] 具有 32 字节的数据: 来自 111.231.221.219 的回复: 字节=32 时间=38ms TTL=52 来自 111.231.221.219 的回复: 字节=32 时间=38ms TTL=52 来自 111.231.221.219 的回复: 字节=32 时间=38ms TTL=52 来自 111.231.221.219 的回复: 字节=32 时间=38ms TTL=52 111.231.221.219Ping 统计信息: 数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失), 往返行程的估计时间(以毫秒为单位): 最短 = 38ms,最长 = 38ms,平均 = 38ms

注意,ping 命令只能用于域名或 IP 地址,无法指定协议或 URI:

C:\Users\Administrator>ping baidu.com/a Ping 请求找不到主机 baidu.com/a。请检查该名称,然后重试。 C:\Users\Administrator>ping http://baidu.com Ping 请求找不到主机 http://baidu.com。请检查该名称,然后重试。 C:\Users\Administrator>ping baidu.com 正在 Ping baidu.com [220.181.57.216] 具有 32 字节的数据: 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=37ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=33ms TTL=55 220.181.57.216Ping 统计信息: 数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失), 往返行程的估计时间(以毫秒为单位): 最短 = 33ms,最长 = 37ms,平均 = 34ms C:\Users\Administrator>ping 220.181.57.216 正在 Ping 220.181.57.216 具有 32 字节的数据: 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 来自 220.181.57.216 的回复: 字节=32 时间=34ms TTL=55 220.181.57.216Ping 统计信息: 数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失), 往返行程的估计时间(以毫秒为单位): 最短 = 34ms,最长 = 34ms,平均 = 34ms

Telnet

Windows 默认安装了 Telnet,通过终端直接使用即可。如果连接成功,会进入会话,回车退出:

C:\Users\Administrator>telnet xxxxxx.com.cn 443 HTTP/1.1 400 Bad Request Server: nginx/1.14.0 Date: Wed, 30 May 2018 05:43:01 GMT Content-Type: text/html Content-Length: 173 Connection: close <html> <head><title>400 Bad Request</title></head> <body bgcolor="white"> <center><h1>400 Bad Request</h1></center> <hr><center>nginx/1.14.0</center> </body> </html> 遗失对主机的连接。

连接失败则直接退出:

C:\Users\Administrator>telnet xxxxxx.com 443 正在连接xxxxxx.com...无法打开到主机的连接。 在端口 443: 连接失败 C:\Users\Administrator>telnet 222.66.184.166 443 正在连接222.66.184.166...无法打开到主机的连接。 在端口 443: 连接失败

OpenSSL

Linux 默认安装了 OpenSSL,可以顺便查看证书等一系列信息:
