并发线程限制
Uimite用于限制当前shell内进程的资源使用
查看默认值
Ulimite -a
全局配置文件 :/etc/security/limits
用途距离
限制堆栈大小:ulimit -s 100
限制shell内存使用:ulimit -m 5000 -v 5000
没有直接对socket数量的限制参数
Linux系统中一切都是文件,运行中的文件叫做进程

电源优化
渗透测试系统耗电较大
延长电池的寿命
无操作挂起、关闭显示器
降低显示器亮度
不使用时关闭无线网卡
开启硬盘省电选项
hdparm -i/dev/sda if AdvancedPM=yes then hdparm -B 1 -S 12/dev/sda
启动笔记本模式
点击root----->系统设置----->电源
在此时间内无操作则挂起:10分钟
关闭屏幕

服务开关
Kali linux 默认未开启所有网络服务
update-rc.d ssh default
update-rc.d ssh start 20 2 3 4 5 .stop 20 0 1 6
运行级别 0 — 6
update-rc.d A defaults 80 20
update-rc.d A defaults 90 10
/etc/init.d/ssh start
0表示关机,6表示重启,1表示单用户模式,2345表示多用户模式
root@kali:~/Desktop# /etc/init.d/ //大量的服务启动脚本
root@kali:~/etc/init.d/# ls -l
root@kali:~/etc/init.d/# ./ssh start //打开ssh
