Centos上安装iftop
我在CentOs服务器上安装iftop时使用如下命令:
yum install libpcap libpcap-devel ncurses ncurses-devel,结果报错如下:
Loaded plugins: product-id, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Setting up Install Process
No package libpcap-devel available.
No package ncurses-devel available.
Nothing to do
这是为什么呢?请教各位大神
