小编给大家分享一下Linux下如何使用Evilscan扫描网络，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
Evilscan 是一个网络扫描器，它运行在 NodeJS 环境中。有许多种选项，允许用户扫描单个 IP 地址或一个范围的IP。它还允许用户选择扫描单个端口或一组端口。
环境
Centos8
npm(Node包管理器)
安装
从github中克隆该仓库，如果系统没有安装git和npm需要提前安装：
[root@localhost ~]# yum -y install git npm[root@localhost ~]# git clone https://github.com/eviltik/evilscan.gitCloning into 'evilscan'...remote: Enumerating objects: 901, done.remote: Counting objects: 100% (178/178), done.remote: Compressing objects: 100% (124/124), done.remote: Total 901 (delta 88), reused 114 (delta 46), pack-reused 723Receiving objects: 100% (901/901), 12.97 MiB | 5.66 MiB/s, done.Resolving deltas: 100% (545/545), done.进入evilscan工作目录并安装：
[root@localhost ~]# cd evilscan/[root@localhost evilscan]# npm install -g evilscan/usr/local/bin/evilscan -> /usr/local/lib/node_modules/evilscan/bin/evilscan.js+ evilscan@1.8.0added 4 packages from 4 contributors in 6.476s使用方式
使用下面命令可以查看evilscan的帮助信息：
[root@localhost ~]# evilscan --helpUsage: evilscan [options]Example: evilscan --target=192.168.0.0/24 --port=21-23,80Options: --port port(s) you want to scan, examples: --port=80 --port=21,22 --port=21,22,23,5900-5900 --reverse display DNS reverse lookup --reversevalid only display results having a valid reverse dns, except if ports specified --geo display geoip (free maxmind) --banner display grabbed banner when available --bannerraw display raw banner (as a JSON Buffer) --bannerlen grabbed banner length in bytes default 512 --progress display progress indicator each seconds --status ports status wanted in results (example --status=OT) T(timeout) R(refused) O(open, default) U(unreachable) --scan scan method tcpconnect (full connect, default) tcpsyn (half opened, not yet implemented) udp (not yet implemented) --concurrency max number of simultaneous socket opened default 500 --timeout maximum number of milliseconds before closing the connection default 2000 --hugescan allow number of ip/port combinaison greater than 16580355 (i.e a /24 network with port range 0-65535) --display display result format (json,xml,console) default console --outfile dump result in a file --json shortcut for --display=json --xml shortcut for --display=xml --console shortcut for --display=console --help display help --about display about --version display version number
使用实例
语法：
evilscan [options]扫描网络中的一台主机上的0-4000端口，抓取banner并仅显示open的端口：
[root@localhost ~]# evilscan 192.168.0.10 --port=0-4000 --banner192.168.0.10|139||open 192.168.0.10|135||open 192.168.0.10|110||open 192.168.0.10|25||open 192.168.0.10|445||open 192.168.0.10|2381||open 192.168.0.10|2301||open 192.168.0.10|3389||open
扫描网络中的一台主机上的0-100端口，抓取banner，仅显示打开的端口，使用json格式输出，每秒显示进度状态：
[root@localhost ~]# evilscan 192.168.0.13 --port=0-100 --banner --isopen --istimeout --progress --json{"_timeStart":"N/A","_timeElapsed":"N/A","_jobsTotal":100,"_jobsRunning":0,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Starting","_message":"Starting"}{"_timeStart":1628685339594,"_timeElapsed":999,"_jobsTotal":100,"_jobsRunning":100,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Running","_message":"Scanning 192.168.0.13:100"}{"_timeStart":1628685339594,"_timeElapsed":2003,"_jobsTotal":100,"_jobsRunning":100,"_jobsDone":0,"_progress":0,"_concurrency":500,"_status":"Running","_message":"Scanning 192.168.0.13:100"}{"ip":"192.168.0.13","port":25,"status":"open"}{"ip":"192.168.0.13","port":22,"banner":"SSH-2.0-OpenSSH_7.9-hpn14v15\\r\\n","status":"open"}{"ip":"192.168.0.13","port":80,"status":"open"}{"_timeStart":1628685339594,"_timeElapsed":2019,"_jobsTotal":100,"_jobsRunning":0,"_jobsDone":100,"_progress":100,"_concurrency":500,"_status":"Finished","_message":"Scanned 192.168.0.13:80"}
提示：并发数默认为100。如果想扫描大量的 ip/端口范围，可以使用 --concurrency 选项（例如 1000）。
如果要突破 1024 个打开套接字的限制，使用下面命令更新限制参数：
