超级快的端口扫描工具blackwater – 作者:Time master

超级快的端口扫描工具blackwater      吊打NMAP

https://github.com/dollarkillerx/blackwater

Blackwater是rust编写基于SCP并发模型的 端口扫描器
官方测试1秒内扫描6W个端口  并且极少的丢包率

吊打传统测试软件NMAP

官方貌似还打算更进分布式版本

ubuntu@ubuntu:~/$ time blackwater -i 110.242.68.3 -p1-65535

Parameter adjustment, solve the problem of packet loss

There are many reasons for packet loss, roughly divided into two.

1. network problems (solution: 1. switch to a better network 2. modify the -ttimeout time)
2. cpu processing super link performance is insufficient (solution: reduce the number of concurrent)

• Extranet scan, not missing a port
  • Modify thread parameters -cCalculation formula: Number of current CPU logical cores * 100
  • Example: Current CPU logical core is 4 cores Parameter is blackwater -i github.com -c 400 -p 1-65535
• Intranet scan, not missing a port
  • Modify thread parameters -cCalculation formula: Number of current CPU logical cores * 250
  • Example: Current CPU logical core is 4 cores Parameter is blackwater -i 192.168.88.11 -c 1000 -p 1-65535
