NSLOOKUP命令的使用方法

由 自古美人都是妖i 提交于 2019-12-20 07:06:05
查询IP地址 nslookup 最简单的用法是查询域名对应的IP地址，包括A记录、MX记录、NS记录CNAME记录。 查询A记录： nslookup 域名 查询MX记录： nslookup -q=mx 域名 查询NS记录： nslookup -q=ns 域名 查询CNAME记录： nslookup 域名 查询域名反向解析是否生效可以使用Windows下的 nslookup 命令 命令格式： nslookup -qa= ptr xxx.xxx.xxx.xxx -qa= ptr 说明查询类型是 PTR 也就是反向查询 后面请跟上你要做反向解析的IP地址 (反向解析是从IP查主机名的解析,所以不用与域名的解析混淆) 如下为一个正确 PTR 解析的输出结果 C:\Users\sony> nslookup -qt= ptr 203.86.5.67 服务器: ns.szptt.net.cn Address: 202.96.134.133:53 非权威应答: 67.5.86.203.in-addr.arpa name = mail.idcsea.net 如果看到类型最后一行的红色部分说明反向解析已经成功。 在线查询:http://www.lbase.net/ReverseDNS 来源： https://www.cnblogs.com/hsapphire/archive/2010/11/19

Why golang Lookup*** function can't provide a server parameter?

由 喜夏-厌秋 提交于 2019-12-18 12:14:42
问题 For nslookup command, it has nslookup somewhere.com some.dns.server . However, it seems that golang dnsclient only load config from /etc/resolv.conf code here: https://golang.org/src/net/dnsclient_unix.go#L225 Does the golang standard library provide something like func LookupTXT(name string, dnsServer string) (txt []string, err error) ? requirement : 1. Don't change the default /etc/resolv.conf . 回答1: @holys "github.com/miekg/dns is too heavy for me" It's not that heavy: package main import

How to perform “nslookup host server”

由 谁说我不能喝 提交于 2019-12-17 07:49:43
问题 My C# service needs to periodically poll nslookup host server . Currently it spawns a Process that executes batch script. Due to performance reason I'm considering to do this check using some API . But the problem is, that using, for example, System.Net.Dns.GetHostAddresses I can only emulate nslookup host check, but not nslookup host server (without seconds param). I've looked at bunch of similar SO questions, but none of them seem to solve my issue. Are there any way to perform nslookup

[System.Net.Dns]::GetHostEntry method resolves IP to HOSTNAME without PTR record?

由 孤街浪徒 提交于 2019-12-12 10:19:47
问题 I am trying to use Dns.GetHostEntry method to get the HOSTNAME for a given IP from the DNS server. According to the documentation, the method first tries to do a reverse lookup on the IP address. In my case this is always successful when I use Dns.GetHostEntry . Now, the strange thing is that for the same IP nslookup doesn't give me anything. It either times out or gives me error: UnKnown can't find 10.4.202.16: Non-existent domain . When I look into the DNS server (2008 R2), I can not find

Batch script for loop & nslookup

由 主宰稳场 提交于 2019-12-12 04:07:26
问题 I've seen this question posted before, but none of the solutions address my issue. I'm simply trying to iterate through a text file that contains host names. When I try the same command (omitting the extra percent signs) from the command line, it will work once or twice then then give the error noted below. Running it as a batch file, the batch file exits without doing anything. This one has really stumped me. Here's the code in my batch file: @echo off set OUTPUTFILE=Results/Results.txt set

centos配置DNS地址

1.先查看一下自己是否有DNS地址 $cat /etc/resolv.conf 文件为空，则是没有配置DNS地址，或者使用nslookup命令解析一下网址。 nslookup www .baidu .com 2.配置DNS地址，编辑resolv.conf文件，此文件只能使用root权限编辑，非root权限无法保存。 $sudo vim /etc/resolv.conf 我添加的第一个是我的上层路由的地址，第二个是google的地址。 3.按esc到命令输入模式，输入:wq保存，再次使用nslookup测试一下，dns是否可用。 参考链接： http://jingyan.baidu.com/article/359911f574f61b57fe030604.html 来源： CSDN 作者： 迷茫十字路 链接： https://blog.csdn.net/ever_peng/article/details/79387774
