命令ping网关检查计算机是否连通代理服务器或者internet

ping网关检查计算机是否连通代理服务器或者inte rnetping ip(自己的)检查网卡ping ip(别人的)检查是否连通内网或者外网

如果网络不通可以按照以下步骤来诊断网络状况

1.Ping本机IP

例如本机IP地址为 222.31.191.211 。则执行命令Ping 222.31.191.211 。如果网卡安装配置没有问题则应有类似下列显示

C:\>ping 222.31.191.211

Pinging 222.31.191.211 with 32 bytes of data:

Reply from 222.31.191.211:bytes=32 time<1ms TTL=128

Reply from 222.31.191.211:bytes=32 time<1ms TTL=128

Ping statistics for 222.31.191.211:

Packets:Sent=4,Rec eived=4,Lost=0(0%los s),

Approximate round trip times in milli-seconds:

Minim um=0m s,Maximum=0m s,Average=0m s

如果在MS-DOS方式下执行此命令显示内容为 Request timed out则表明网卡安装或配置有问题。将网线断开再次执行此命令如果显示正常则说明本机使用的IP地址可能与另一台正在使用的机器IP地址重复了。如果仍然不正常则表明本机网卡安装或配置有问题需继续检查相关网络配置。

2.Ping网关IP

假定网关IP为 222.31.191.110则执行命令“Ping 222.31.191.110”。在MS-DOS方式下执行此命令如果显示类似以下信息

Pinging 222.31.191.110 with 32 bytes of data:

Reply from 222.31.191.110:bytes=32 time<1ms TTL=255

Reply from 222.31.191.110:bytes=32 time<1ms TTL=255

Reply from 222.31.191.110:bytes=32 time<1ms TTL=255

Reply from 222.31.191.110:bytes=32 time<1ms TTL=255

Ping statistics for 222.31.191.110:

Packets:Sent=4,Rec eived=4,Lost=0(0%los s),

Approximate round trip times in milli-seconds:

Minim um=0m s,Maximum=0m s,Average=0m s

则表明局域网中的网关路由器正在正常运行。反之则说明网关设置有问题请检查IP网关等信息是否设置正确。

3.Ping远程IP

这一命令可以检测本机能否正常访问Internet。 比如林大主页的IP地址为 202.204.112.68。在MS-DOS方式下执行命令 “Ping 202.204.112.68”如果屏幕显示

Pinging 202.204.112.68 with 32 bytes of data:

Reply from 202.204.112.68:bytes=32 time<1ms TTL=63

Reply from 202.204.112.68:bytes=32 time<1ms TTL=63

Reply from 202.204.112.68:bytes=32 time<1ms TTL=63

Reply from 202.204.112.68:bytes=32 time<1ms TTL=63

Ping statistics for 202.204.112.68:

Packets:Sent=4,Rec eived=4,Lost=0(0%los s),

Approximate round trip times in milli-seconds:

Minim um=0m s,Maximum=0m s,Average=0m s

则表明运行正常能够正常接入内部网。反之则表明网络设置存在问题或IP绑定不正确。

4.Ping DNS IP

这一命令用于检查内部网的DN S是否工作正常如果您可以正常联网但是输入域名却无法解析时请尝试该命令“ping 202.204.112.66”如果显示

Pinging 202.204.112.66 with 32 bytes of data:

Reply from 202.204.112.66:bytes=32 time<1ms TTL=63

Reply from 202.204.112.66:bytes=32 time<1ms TTL=63

Reply from 202.204.112.66:bytes=32 time<1ms TTL=63

Ping statistics for 202.204.112.66:

Packets:Sent=4,Rec eived=4,Lost=0(0%los s),

Approximate round trip times in milli-seconds:

Minim um=0m s,Maximum=0m s,Average=0m s

则表明DNS服务器工作正常如果显示“Request timed out.”请马上联系信息中心。
