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 http://www.thc.org/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) 2014 by van Hauser / THC www.thc.org

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 gnucitizen.org.

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。

 近期,安全牛课堂在做此类线上培训,感兴趣可以了解
