FreeBSD下用bandwidthd监控网络流量
FreeBSD下用bandwidthd监控网络流量
在流量统计常用免费软件中有mrtg,ntop,bandwidthd等多种,
mrtg 只是显示某一网络接口的总量, ntop详细但也较占系统资源。
现在试试bandwidthd,它可在各种unix下运行。
网关上装上'bandwidthd' ,就可以追踪的是各个的 IP 的流量,而且可以用图象曲线显示各个ip的相应不同协议显示,还能分时段查看
例如包含HTTP, TCP, UDP, ICMP, VPN 以及 P2P 协议的各自流量,以ip为统计对象。
默认的颜色,TCP为绿色;HTTP为蓝色;FTP为浅蓝;P2P为粉红;UDP为棕褐色; ICMP为红色。
安装:
更新ports后,
cd /usr/ports/net-mgmt/bandwidthd/
make -s install distclean
就装好了。
在你的web的根目录建立一个叫bandwidth的目录,
ln -s /web的根目录/bandwidth/ /usr/local/bandwidthd/htdocs
cp /usr/local/bandwidthd/etc/bandwidthd.conf-dist /usr/local/bandwidthd/etc/bandwidthd.conf
修改配置:
vi /usr/local/bandwidthd/etc/bandwidthd.conf
一般修改一下网段和掩码,其他的用默认值即可,如果你熟悉英文,就看看其他选项.大概如下
编辑:
/usr/local/bandwidthd/etc/bandwidthd.conf

把其中 subnet 的设定,以一网段为例:
subnet 192.168.1.0 255.255.255.0

65
item "UDP" 0x800000 udp all
item "ICMP" 0xff0000 icmp all
运行:
cp /usr/local/etc/rc.d/bandwidthd.sh.sample /usr/local/etc/rc.d/bandwidthd.sh
/usr/local/etc/rc.d/bandwidthd.sh start
以后server启动后,会自动启动 bandwidthd进程。
过几分钟后,打开
http://服务器ip/bandwidth/
就可以看到统计结果了。
