FreeBSD使用logwatch分析記錄檔，並透過Gmail寄出分析結果

Step1)安裝logwatch

#pkg install  logwatch

Step2)設定logwatch，將分析結果儲存到檔案/var/log/logwatch

#ee /usr/local/etc/logwatch/defaults/logwatch.conf

Output = file

Filename = /var/log/logwatch

Range = Today

Step3)使用logwatch分析記錄檔

#logwatch.pl

定時執行logwatch.pl

# ee /etc/crontab

58      23      *       *       *       root    /usr/local/sbin/logwatch.pl

Step4)編輯logwatch.sh，新增標題與寄送給Gmail

/usr/home/jang/logwatch.sh

#!/bin/sh

awk 'NR==1{print "Subject: LogWatch 13\n\n"}1' /var/log/logwatch > /var/log/logwatch2

ssmtp zsg101101@gmail.com < /var/log/logwatch2

讓logwatch.sh具有執行權限

#chmod 700  logwatch.sh

定時執行logwatch.sh

# ee /etc/crontab

59      23      *       *       *       root    /usr/home/jang/logwatch.sh

Step5)修改root的名稱，預設為Charlie &，會影響寄件者名稱

#chpass
