HOME_NET = 'any' --> HOME_NET = '192.168.50.19/24'
EXTERNAL_NET = 'any' --> EXTERNAL_NET = '!$HOME_NET'

5 snort檢驗規則，19500+條
snort -c /usr/local/snort/etc/snort/snort.lua
六 運行，測試
1 自定義一條ping測試的規則
#增加本地規則庫
sudo vim /usr/local/snort/etc/rules/local.rules
alert icmp any any -> $HOME_NET any (msg:"ICMP connection test"; sid:1000001; rev:1;)
#測試規則正確
snort -c /usr/local/snort/etc/snort/snort.lua -R /usr/local/snort/etc/rules/local.rules2 啟動snort?
#配置日志
sudo vim /usr/local/snort/etc/snort/snort.lua
