将 NETBIOS 域转换为 FQDN(完全限定域名)(Translating NETBIOS domain into a FQDN (Fully Qualified Domain Name))

问题 简而言之 - 如何将 NETBIOS 域转换为 FQDN? 详细信息:假设我在域 A 中,并且我拥有域 B 的用户凭据,该域与域 A 具有信任关系(我可以对凭据进行身份验证)。 当我拥有的只是来自该域的某些经过身份验证的用户的凭据(包括 netbios 域名)时,如何获取域 B 的 FQDN? 我正在用 C# 编码,但也欢迎使用 COM/WMI/Win32 解决方案。 回答1 这可能不是最佳选择,但看起来您可以进行 NetBIOS 名称查询以获取 IP 地址,然后进行反向 DNS 查找以从中获取 FQDN... http://www.protocolbase.net/protocols/protocol_NBNS.php (反向DNS步骤很容易查到) 回答2 您对另一个域有什么样的访问权限? 您针对另一个域中的哪个服务器/服务进行身份验证? 您是否可以访问其他域中的域服务器? 如果是这样,那么您可以拨打这样的电话: DirectoryEntry rootDSE = new DirectoryEntry("LDAP://10.11.12.13/rootDSE", @"DOMAIN\Username", "Password"); Console.WriteLine(rootDSE.Properties["defaultNamingContext"].Value); (将 10

Mail of PHP, DNS request timed out, and FQDN

I want to make mail() of PHP work in my Windows Server 2012 R2. To this end, I first installed SMTP by following this page. One thing that confuses me is the Full-qualified domain name. WIN-RFELH8GM0KN is what it proposes by default. My server hosts several websites, does anyone know which website I should specify here? I did not change this, as a consequence, mail www.google.com in nslookup returns DNS request timed out. So is it an error? Of cause, my test.php does not send the mail: <?php mail('mymail@gmail.com', 'title', 'content'); ?> Could anyone help? Update 1 Following the answer of

How to configure FQDN in ovirt engine

I want to configure oVirt in Vultr bare metal server. But I don't know how to configure Engine VM FQDN. It always tell me The address proposed for this host does not resolves locally. There is error message: And I've already configure my /etc/hosts file. Here is my /etc/hosts code: 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 guest ::1 guest 127.0.0.1 VTest ::1 VTest 149.28.103.174 ovirt 127.0.0.2 test I've tried FQDN guest,localhost,ovirt,localhost.localdomain.

Validate FQDN in C#

Does anyone have a Regular Expression to validate legal FQDN? Now, I use on this regex: (?=^.{1,254}$)(^(?:(?!\d+\.|-)[a-zA-Z0-9_\-]{1,63}(?!-)\.?)+(?:[a-zA-Z]{2,})$) However this regex results in "aa.a" not being valid while "aa.aa" is valid. Does anyone know why?

How do you find the FQDN of the local host?

How do you find the FQDN of the local host in Go? BTW: net.LookupAddr() doesn't work on Windows. So that's not an option.

Translating NETBIOS domain into a FQDN (Fully Qualified Domain Name)

In short - How do I translate a NETBIOS domain to a FQDN ? Details: Assuming I'm in domain A and I have user credentials for domain B which has a trust relationship with domain A (I can authenticate the credentials). How do I get domain B's FQDN when all I have are the credentials of some authenticated user from that domain, including the netbios domain name? I'm coding in C# but a COM/WMI/Win32 solution would be welcomed as well.

在启动时为GCE实例配置FQDN(Configuring FQDN for GCE instance on startup)

问题 我正在尝试使用预先配置的FQDN启动Google计算引擎(GCE)实例。 我们打算运行基于/ etc / hosts内容获得许可的应用程序。 我正在使用Google Cloud SDK实用程序-gcloud启动实例。 我尝试使用元数据选项设置“主机名”键,如下所示: gcloud compute instances create mynode (standard opts) --metadata hostname=mynode.example.com 每当我在计算机实例下登录开发人员控制台时,都可以在“自定义元数据”下看到主机名。 这似乎是一个新的自定义键-它对以下内容没有影响: http://metadata.google.internal/computeMetadata/v1/instance/hostname 返回。 我也尝试过像下面那样设置“实例/主机名”,这在使用gcloud时会导致解析错误。 --metadata instance/hostname=mynode.example.com 我已成功使用元数据服务器的启动脚本功能来运行启动脚本,该脚本可解析新创建的实例(更新的/ etc / hosts)的新内部IP地址。 这似乎可行,但感觉不像“谷歌方式”。 我可以在实例创建过程中使用metaserver功能配置实例的FQDN (特别是域名,因为实例名称始终是主机名

将powershell命令的输出保存在变量中并在批处理脚本中使用它吗?(Save the output of a powershell command in a variable and use it in batch script?)

问题 我想做的是保存powershell命令的输出(从批处理脚本运行),并在批处理脚本中使用它。 你能告诉我该怎么办吗? 电源外壳命令为: [System.Net.Dns]::GetHostByName((hostname)).HostName 我想在批处理脚本中使用输出。 聚苯乙烯 如果我可以从cmd而不是从powershell中获得完整的计算机名称/主机名/完全限定的域名(FQDN),那就更好了。 但是完整的计算机名称不是ComputerName和UserDNSDomain变量的串联。 回答1 for /f "tokens=*" %%i in ('powershell /command "[System.Net.Dns]::GetHostByName((hostname)).HostName"') do set return=%%i echo %return% 回答2 您可以使用nslookup批量执行此操作,该查询执行相同的DNS搜索: for /f "tokens=1*" %%a in ('nslookup hostname ^| findstr /i "name"') do set return=%%b echo Hello '%return%'

将带有FQDN的URL(TLD后加点)重定向为与PQDN等效的URL(Redirect URLs with FQDN (dot after TLD) to equivalent with PQDN)

问题 可以使用FQDN来访问许多网站(即,在TLD后面加一个点): https://www.ebay.com./ https://www.google.com./ https://www.reddit.com./ https://stackoverflow.com./ https://zh.wikipedia.org./wiki/Main_Page 某些网站无法通过这种方式访问​​,但我现在找不到示例。¹² 在.htaccess文件中,是否可以将带点后缀的所有变.htaccess定向到不带后缀的变体? 理想情况下,使用“通配符”规则,这样您就不必显式列出域(无需编辑即可在不同的站点/域上使用它)。 重定向示例: http://example.com./ http://example.com/ http://example.com./foo http://example.com/foo http://sub.example.com./bar.html http://sub.example.com/bar.html ¹当通过HTTP访问时,stackoverflow.com会产生HTTP错误400:“错误请求-无效的主机名”。 ²Wikipedia,当通过HTTPS访问时(仍为可选),曾用于给出证书错误:“该证书仅对以下名称有效: *.wikipedia.org , wikipedia

关于hostname和fqdn的区别和获取及设置

很多应用软件会涉及到fqdn如salt获取到的fqnd和host可能会不一样,两者有何区别? THE FQDN You can’t change the FQDN (as returned by hostname --fqdn) or the DNS domain name (as returned by dnsdomainname) with this command. The FQDN of the system is the name that the resolver(3) returns for the host name. Technically: The FQDN is the name gethostbyname(2) returns for the host name returned by gethostname(2). The DNS domain name is the part after the first dot. Therefore it depends on the configuration (usually in /etc/host.conf) how you can change it. Usually (if the hosts file is parsed before DNS or NIS) you can change it in
