使用 dnscmd 更改 SOA 上的 TTL

  • 772

嗨，我在我的 Windows Server 2012 上使用 dnsmcd 命令来从 csv 文件创建新区域。

但我需要更改 SOA 记录上的 TTL，所以我尝试这样做：

dnscmd /recordadd example.com `@ 300 SOA

但我有这个错误：

Command failed:  DNS_ERROR_RECORD_FORMAT     9702    0x25E6

有办法吗？

dns-zone windows-server-2012 windows-dns

    这是修改授权开始记录的正确格式

    dnscmd /recordadd zonename @ SOA primaryDNSservername responsibleemailipaddress serialnumber refreshinterval retryinterval expireinterval defaultTTL

  2. 如果您想知道为什么在尝试更改 SOA 记录（即增加区域的序列号）时收到此错误DNS_ERROR_RECORD_ALREADY_EXISTS，请检查您要更改的序列号（新序列号）是否实际上高于当前序列号. 此错误消息令人困惑，所以我希望它不会让您头疼，直到您弄清楚原因。

    如果您觉得它有用，我会使用此脚本，因为在 200 左右的区域上单击“增加”对我来说太过分了。

    rem  To increase serial on all zones: copy this to a script, as functions cannot be use from CLI

echo on

rem  get the intersting zones first that you want to change
echo. > %TEMP%\dnszones.txt
for /f %%z in ('dnscmd /enumzones ^| findstr in-addr.arpa') do echo %%z >> %TEMP%\dnszones.txt

rem  take existing serials from all zones
for /f %%z in (%TEMP%\dnszones.txt) do dnscmd /zoneprint %%z | findstr SOA > %TEMP%\dns.%%z.txt

rem  read the serials and increase them
for /f %%z in (%TEMP%\dnszones.txt) do for /f "tokens=1-8*" %%a in (%TEMP%\dns.%%z.txt) do call:increase_serial %%z %%e

goto end

:increase_serial
rem arg1=%~1 is the zone name, arg2 is existing serial
@rem  example format of the SOA record
@rem         3600 SOA   servername.domain.com. hostmaster.domain.com. 13 900 600 86400 3600

@rem  as per https://technet.microsoft.com/en-us/library/cc816941(v=ws.10).aspx
@rem  var a is minimum-default-ttl - optional
@rem  var b is string SOA
@rem  var c is PrimSvr - server name with dot
@rem  var d is Admin - contact for admin
@rem  var e is serial
@rem  var f is Refresh - in seconds
@rem  var g is Retry - in seconds
@rem  var h is Expire - in seconds
@rem  var i is MinTTL - in seconds

set /a INCREASED_SERIAL=%~2+1
@echo increase serial from %~2 to %INCREASED_SERIAL% on zone %1
for /f "tokens=1-8*" %%a in (%TEMP%\dns.%~1.txt) do dnscmd /RecordAdd %~1 @ SOA %%c %%d %INCREASED_SERIAL% %%f %%g %%h %%i
goto :eof

:end
