如何使用PowerShell删除单个NAPTR记录? [英] How to use PowerShell to delete a single NAPTR record?
问题描述
我使用GUI创建了新的NAPTR记录.但是，我想使用PowerShell删除其中之一.
I created a new NAPTR records using the GUI. However I'd like to delete one of them using PowerShell.
我可以证明有2条记录:
I can prove there are 2 records:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo NAPTR 35 0 01:00:00
foo NAPTR 35 0 01:00:00
> $OldObj = Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
> $OldObj[0].RecordData.Data
010001000155036F6E65036F6E6500
> $OldObj[1].RecordData.Data
0200020001550374776F0374776F00
> $OldObj[2].RecordData.Data
>
如果我尝试删除记录，则可以以交互方式进行:
If I try to delete the records, I can do it interactively:
> Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
不幸的是，这两个记录都被删除！
Sadly that deletes both of the records!
如果我改为尝试删除该对象怎么办?
What if I try to remove the object, instead?
> $OldObj[1] | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to
continue?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
Get-DnsServerResourceRecord: Failed to get foo record in example.com zone on TOMDEV server.
哦，不！那删除了两条记录！
Oh no! That deleted both records!
我可以指定一条记录到 Remove-DnsServerResourceRecord 吗?
Can I specify a single record to Remove-DnsServerResourceRecord?
这是我尝试过的:
这完全被拒绝了:
> Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR -RecordData "0200020001550374776F0374776F00"
Remove-DnsServerResourceRecord: InputObject for resource record has an invalid value. Failed to remove the resource record on TOMDEV server. Please check extended error for additional details.
如果我尝试捕获一条记录并将其通过管道传送到 Remove-，则会删除两条记录:
If I try to capture the one record and pipe it to Remove-, that removes both records:
# First, we single out exactly one record:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" }
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo NAPTR 35 0 01:00:00
>
# That worked! Let's use that query and pipe it to Remove!
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" } | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -Force
# Nope, that removed both records!
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
Get-DnsServerResourceRecord: Failed to get foo record in example.com zone on TOMDEV server.

这不是删除"foo"处的所有内容，只是NAPTR记录在那里.(实际上，该消息说的是记录集"(复数)，而不是记录".
It isn't removing everything at "foo", just the NAPTR records there. (In fact, the message says "record sets" (plural), not "record".
让我们证明，通过创建A记录加上2个NAPTR记录，所有记录均位于标签"foo"处.我们将看到相同的问题:
Let's prove that by creating an A record plus 2 NAPTR records all at label "foo". We'll see the same problem:
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
HostName RecordType Type Timestamp TimeToLive RecordData
-------- ---------- ---- --------- ---------- ----------
foo A 1 0 01:00:00 4.4.4.4
foo NAPTR 35 0 01:00:00
foo NAPTR 35 0 01:00:00
> $OldObj = Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType naptr
> $OldObj[0].RecordData.Data
010001000155036F6E65036F6E6500
> $OldObj[1].RecordData.Data
0200020001550374776F0374776F00
> $OldObj[2].RecordData.Data
> Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR | Where-Object {$_.HostName -eq "foo" -and $_.RecordData.Data -eq "0200020001550374776F0374776F00" } | Remove-DnsServerResourceRecord -ZoneName "example.com" -Name "foo"
Confirm
Removing DNS resource record set by name foo of type NAPTR from zone example.com on TOMDEV server. Do you want to
continue?

推荐答案
如果您要删除其中之一，则不要紧要删除其中之一，也要说您也尝试过此操作:
If you are saying you want to delete one of them, and it does not matter which one, are saying you also tried this:
Get-DnsServerResourceRecord -ZoneName "example.com" -Name "foo" -RRType NAPTR |
Where-Object {
$PSItem.HostName -eq "foo" -and
$PSItem.RecordData.Data -eq "0200020001550374776F0374776F00"
} |
Select-Object -First 1 |
Remove-DnsServerResourceRecord -WhatIf
