网络工具箱

网络工具箱提供了网络命令运行界面，使得ping , tracert，查看网络连接命令方便的运行，同时可将结果记录到数据库，可根据时间、IP地址、域名或者命令类型进行查询。为网络排障提供了便利的条件。

怎样PING IP

ping 网关 检查计算机是否连通代理服务器或者internet
ping 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
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, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
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, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
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, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
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DNS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
Reply from 202.204.112.66: bytes=32 time<1ms TTL=63

Ping statistics for 202.204.112.66:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
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。
