本文将介绍如何在Debian或其他Linux版本下安装调试SARG。
SARG代表Squid Analysis Report Generator，是一款能够生成图形界面流量报告的免费软件。
在Ubuntu下你可以通过以下命令得以安装：
apt-get install sarg
但是在debian下你需要首先修改source.list然后进行下载，完全步骤如下：
1. 打开/etc/apt/source.list
2. 添加以下命令行到source.list：
deb http://backports.debian.org/debian-backports squeeze-backports mail
3. 更新list：apt-get update
4. 下载并安装SARG：apt-get install sarg
安装后调试/etc/sarg/sarg.conf ，将文件调试成以下：

5. 如果没有安装apache2，需要安装apache2
apt-get install apache2
6. 都完成后，通过 http://ip-address/squid-reports/ 来访问
7. 调试exclude_users和exclude_hosts设定规则
