nload 是一个命令行应用程序,nload 能够实时的监控网络流量和带宽使用情况。
下载 nload 并释放。现在的版本是 0.7.3。安装 gcc 包。

[root@searu ~]# wget
[root@searu ~]# tar xzf nload-0.7.3.tar.gz
[root@searu ~]# rpm -qa | grep gcc
[root@searu ~]# yum install gcc

进入 nload-0.7.3 目录并预配置。
[root@searu ~]# cd nload-0.7.3
[root@searu nload-0.7.3]# ./configure

configure: error: ncurses library or development files not found. ncurses is required for nload.

找了下问题,ncurses-devel 包没有安装。
[root@searu nload-0.7.3]# yum install ncurses-devel
