Usage: host [-aCdlriTwv] [-c class] [-N ndots] [-t type] [-W time]
[-R number] [-m flag] hostname [server]
-a is equivalent to -v -t ANY
-c specifies query class for non-IN data
-C compares SOA records on authoritative nameservers
-d is equivalent to -v
-l lists all hosts in a domain, using AXFR
-i IP6.INT reverse lookups
-N changes the number of dots allowed before root lookup is done
-r disables recursive processing
-R specifies number of retries for UDP packets
-s a SERVFAIL response should stop query
-t specifies the query type
-T enables TCP/IP mode
-v enables verbose output
-w specifies to wait forever for a reply
-W specifies how long to wait for a reply
-4 use IPv4 query transport only
-6 use IPv6 query transport only
-m set memory debugging flag (trace|record|usage)

more命令，功能类似 cat ，cat命令是整个文件的内容从上到下显示在屏幕上。 more会以一页一页的显示方便使用者逐页阅读，而最基本的指令就是按空白键（space）就往下一页显示，按 b 键就会往回（back）一页显示，而且还有搜寻字串的功能 。more命令从前向后读取文件，因此在启动时就加载整个文件。
more命令和cat的功能一样都是查看文件里的内容，但有所不同的是more可以按页来查看文件的内容，还支持直接跳转行等功能。

安装dnsdict6
wget /releases/thc-ipv6-2.7.tar.gz
使用上面的命令会出现证书错误，在本机下载然后拖进虚拟，最后打开终端开始安装！
tar zvxf thc-ipv6-2.7.tar.gz
cd thc-ipv6-2.7
sudo apt-get install libpcap-dev libssl-dev
make
sudo cp dnsdict6 /usr/bin/
【课外拓展】说明： 用来枚举域服务器的，它使用你提供的一个字典或者内置的列表来枚举
语法：dnsdict6 [-d46] [-s|-m|-l|-x] [-t 线程] [-D] 域名 [字典路径]
参数说明:
-4 显示ipv4
-t 指定要使用的线程 默认：8 最大:32
-D ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝［只显示字典不扫描］＝＝＝＝
-d 显示在DNS服务器上的NS（一种服务记录类型）MX（邮件服务器） ipv6 的域名信息
-e 忽略没有NS域错误
-S 执行SRV服务名称猜测
-[smlx] 选择字典大小[内置的] -s 小型是50条 -m 中等是796条[默认] -l 大型1416条 -x 最大3211条

dnsdict6 v2.7 (c) by van Hauser / THC <vh@>
Syntax: dnsdict6 [-d4] [-s|-m|-l|-x|-u] [-t THREADS] [-D] domain [dictionary-file]
Enumerates a domain for DNS entries, it uses a dictionary file if supplied
or a built-in list otherwise. This tool is based on dnsmap by .
Options:
-4 do also dump IPv4 addresses
-t NO specify the number of threads to use (default: 8, max: 32).
-D dump the selected built-in wordlist, no scanning.
-d display IPv6 information on NS and MX DNS domain information.
-e ignore no NS for domain errors
-S perform SRV service name guessing
-[smlxu] choose the dictionary size by -s(mall=100), -m(edium=1419) (DEFAULT)
-l(arge=2601), -x(treme=5886) or -u(ber=16724)

Security+认证为什么是互联网+时代最火爆的认证？
牛妹先给大家介绍一下Security+
Security+ 认证是一种中立第三方认证，其发证机构为美国计算机行业协会CompTIA ；是和CISSP、ITIL 等共同包含在内的国际 IT 业 10 大热门认证之一，和CISSP偏重信息安全管理相比，Security+ 认证更偏重信息安全技术和操作。
通过该认证证明了您具备网络安全，合规性和操作安全，威胁和漏洞，应用程序、数据和主机安全，访问控制和身份管理以及加密技术等方面的能力。因其考试难度不易，含金量较高，目前已被全球企业和安全专业人士所普遍采纳。
Security+认证如此火爆的原因？
原因一：在所有信息安全认证当中，偏重信息安全技术的认证是空白的，Security+认证正好可以弥补信息安全技术领域的空白 。
目前行业内受认可的信息安全认证主要有CISP和CISSP，但是无论CISP还是CISSP都是偏重信息安全管理的，技术知识讲的宽泛且浅显，考试都是一带而过。而且CISSP要求持证人员的信息安全工作经验都要5年以上，CISP也要求大专学历4年以上工作经验，这些要求无疑把有能力且上进的年轻人的持证之路堵住。在现实社会中，无论是找工作还是升职加薪，或是投标时候报人员，认证都是必不可少的，这给年轻人带来了很多不公平。而Security+的出现可以扫清这些年轻人职业发展中的障碍，由于Security+偏重信息安全技术，所以对工作经验没有特别的要求。只要你有IT相关背景，追求进步就可以学习和考试。
原因二：IT运维人员工作与翻身的利器。
在银行、证券、保险、信息通讯等行业，IT运维人员非常多，IT运维涉及的工作面也非常广。是一个集网络、系统、安全、应用架构、存储为一体的综合性技术岗。虽然没有程序猿们“生当做光棍，死亦写代码”的悲壮，但也有着“锄禾日当午，不如运维苦“的感慨。天天对着电脑和机器，时间长了难免有对于职业发展的迷茫和困惑。Security+国际认证的出现可以让有追求的IT运维人员学习网络安全知识，掌握网络安全实践。职业发展朝着网络安全的方向发展，解决国内信息安全人才的匮乏问题。另外，即使不转型，要做好运维工作，学习安全知识取得安全认证也是必不可少的。
原因三：接地气、国际范儿、考试方便、费用适中！
CompTIA作为全球ICT领域最具影响力的全球领先机构,在信息安全人才认证方面是专业、公平、公正的。Security+认证偏重操作且和一线工程师的日常工作息息相关。适合银行、证券、保险、互联网公司等IT相关人员学习。作为国际认证在全球147个国家受到广泛的认可。
在目前的信息安全大潮之下，人才是信息安全发展的关键。而目前国内的信息安全人才是非常匮乏的，相信Security+认证一定会成为最火爆的信息安全认证。
