Linux下使用Evilscan掃描網絡
Evilscan 是一個網絡掃描器，它運行在 NodeJS 環(huán)境中。有許多種選項，允許用戶掃描單個 IP 地址或一個范圍的IP。它還允許用戶選擇掃描單個端口或一組端口。
環(huán)境
Centos8
npm(Node包管理器)
安裝
從github中克隆該倉庫，如果系統(tǒng)沒有安裝git和npm需要提前安裝：
[root@localhost ~]# yum -y install git npm
[root@localhost ~]# git clone https://github.com/eviltik/evilscan.git

使用方式
使用下面命令可以查看evilscan的幫助信息：
[root@localhost ~]# evilscan --help
Usage: evilscan [options]
Example: evilscan --target=192.168.0.0/24 --port=21-23,80

如何使用evilscan 掃描網絡如何使用evilscan 掃描網絡
使用實例
語法：
evilscan [options]
掃描網絡中的一臺主機上的0-4000端口，抓取banner并僅顯示open的端口：
[root@localhost ~]# evilscan 192.168.0.10 --port=0-4000 --banner
192.168.0.10|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
掃描網絡中的一臺主機上的0-100端口，抓取banner，僅顯示打開的端口，使用json格式輸出，每秒顯示進度狀態(tài)：
[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：并發(fā)數默認為100。如果想掃描大量的 ip/端口范圍，可以使用 --concurrency 選項（例如 1000）。
如果要突破 1024 個打開套接字的限制，使用下面命令更新限制參數：
ulimit -u unlimited
