[课后拓展]关于kali linux中无RPM命令无法使用的问题,本人在自己的机器上通过以下方法修正了,
身为kali linux的初学者,如果你用了我的方法将问题解决了最好,如果没有解决请见谅。
------------------------------------------
RPM是RedHat Package Manager(RedHat软件包管理工具)。
在进入kali linux 终端输入RPM,如果提示没有安装的情况的时候
那么这个命令是不能使用的。解决方法是通过改用163的源,更新后使用RPM。
下载163的源
wget http://mirrors.163.com/.help/sources.list.squeeze
注释后面3行
vi sources.list.squeeze
复制到该位置
cp sources.list.squeeze /etc/apt/sources.list
apt-get update
上述操作结束后重启客户端即可使用RPM命令。

nmap 1.1.1.1-254-sn
nmap -iL iplist.txt -sn
Nmap很轻大,后面单独介绍
root@kali:~# nmap
Nmap 6.49BETA4 ( https://nmap.org )
Usage: nmap [Scan Type(s)] [Options] {target specification}
TARGET SPECIFICATION:
Can pass hostnames, IP addresses, networks, etc.
Ex: scanme.nmap.org, microsoft.com/24, 192.168.0.1; 10.0.0-255.1-254
-iL
-iR
--exclude
--excludefile
HOST DISCOVERY:
-sL: List Scan - simply list targets to scan
-sn: Ping Scan - disable port scan
-Pn: Treat all hosts as online -- skip host discovery
-PS/PA/PU/PY[portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports
-PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes
-PO[protocol list]: IP Protocol Ping
-n/-R: Never do DNS resolution/Always resolve [default: sometimes]
--dns-servers
--system-dns: Use OS's DNS resolver
--traceroute: Trace hop path to each host
SCAN TECHNIQUES:
-sS/sT/sA/sW/sM: TCP SYN/Connect()/ACK/Window/Maimon scans
-sU: UDP Scan
-sN/sF/sX: TCP Null, FIN, and Xmas scans
--scanflags
-sI
-sY/sZ: SCTP INIT/COOKIE-ECHO scans
-sO: IP protocol scan
-b
PORT SPECIFICATION AND SCAN ORDER:

Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080,S:9
--exclude-ports
-F: Fast mode - Scan fewer ports than the default scan
-r: Scan ports consecutively - don't randomize
--top-ports
--port-ratio
SERVICE/VERSION DETECTION:
-sV: Probe open ports to determine service/version info
--version-intensity
--version-light: Limit to most likely probes (intensity 2)
--version-all: Try every single probe (intensity 9)

--script-updatedb: Update the script database.
--script-help=
script-categories.
OS DETECTION:
-O: Enable OS detection
--osscan-limit: Limit OS detection to promising targets
--osscan-guess: Guess OS more aggressively
TIMING AND PERFORMANCE:
Options which take
's' (seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m).
-T<0-5>: Set timing template (higher is faster)
--min-hostgroup/max-hostgroup
--min-parallelism/max-parallelism
--min-rtt-timeout/max-rtt-timeout/initial-rtt-timeout

and Grepable format, respectively, to the given filename.
-oA
-v: Increase verbosity level (use -vv or more for greater effect)
-d: Increase debugging level (use -dd or more for greater effect)
--reason: Display the reason a port is in a particular state
--open: Only show open (or possibly open) ports
--packet-trace: Show all packets sent and received
--iflist: Print host interfaces and routes (for debugging)
--append-output: Append to rather than clobber specified output files
