Nethogs 是一个终端下的网络流量监控工具,它的特别之处在于可以显示每个进程的带宽占用情况,这样可以更直观获取网络使用情况。它支持 IPv4 和 IPv6 协议、支持本地网卡及 PPP 链接。

下载:

从SourceForge上下载nethogs-0.8.0.tar.gz

使用wget下载:

wget http://sourceforge.net/projects/nethogs/files/nethogs/0.8/nethogs-0.8.0.tar.gz/download

安装:

个人补充:

首先,需要g++编译器,因为nethogs是使用c++编写,即.cpp结尾的文件,必须使用g++进行编译,如果是.c,使用gcc编译器即可。

# rpm -ivh libstdc++-devel-4.1.2-51.el5.x86_64.rpm

# rpm -ivh gcc-c++-4.1.2-51.el5.x86_64.rpm

# ls /mnt/Server/ |grep ncur
ncurses-5.5-24.20060715.i386.rpm
ncurses-5.5-24.20060715.x86_64.rpm
ncurses-devel-5.5-24.20060715.i386.rpm
ncurses-devel-5.5-24.20060715.x86_64.rpm
php-ncurses-5.1.6-27.el5_5.3.x86_64.rpm

然后,需要先 yum install ncurses*,如果安装提示需要下载,可以直接使用rpm -ivh 安装即可,具体安装,如上所示。
