如何使用PowerShell测试远程计算机的连接?
要使用PowerShell测试远程连接,请使用Test-Connection命令。PowerShell还支持Ping命令,并且两个命令几乎产生相同的输出,但Test-Connection cmdlet支持高级参数。查看两个命令输出的外观。
ping命令 -
PS C:\Temp> ping Test1-Win2k16Pinging Test1-Win2k16 [192.168.0.108] with 32 bytes of data:
Reply from 192.168.0.108: bytes=32 time<1ms TTL=128
Reply from 192.168.0.108: bytes=32 time=1ms TTL=128

Ping statistics for 192.168.0.108:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 1ms, Average = 0ms
测试连接命令输出-
PS C:\Scripts> Test-Connection Test1-win2k16Source Destination IPV4Address IPV6Address
------ ----------- ----------- -----------
ADDC Test1-win2k16 192.168.0.108
ADDC Test1-win2k16 192.168.0.108
ADDC Test1-win2k16 192.168.0.108
ADDC Test1-win2k16 192.168.0.108
您可以使用-Count参数减少检查次数。它与ping命令中的-n相似。
例
PS C:\Scripts> Test-Connection Test1-win2k16 -Count 2Source Destination IPV4Address IPV6Address
------ ----------- ----------- -----------
ADDC Test1-win2k16 192.168.0.108
ADDC Test1-win2k16 192.168.0.108
如果您需要安静地执行上述命令,则可以使用-Quiet参数,如果连接成功或失败,则该参数将给出布尔值(True或False)。
PS C:\Scripts> Test-Connection Test1-win2k16 -Count 2 -QuietTrue
Test-Connection的优点是它支持常见的参数,例如处理错误。在以下示例中,Any-Comp服务器不存在。为了在服务器不可访问或服务器名称不存在时捕获错误,我们将使用cmdlet支持的ErrorAction参数。
try {Test-Connection Any-Comp -Count 2 -ErrorAction Stop
}
catch {
$_.Exception.Message
}
输出结果
Testing connection to computer 'Any-Comp' failed: Cannot resolve the target name.
