How to install TACACS+ on Linux CentOS
TACACS+ (Terminal Access Controller Access-Control System Plus) is commonly used to authenticate network devices like routers and switches using a central server. Instead of using the local database on a router or switch, we can use the credentials that are stored on the TACACS+ server. Whenever you try to log onto a network device, the credentials that you supply will be forwarded to the TACACS+ server. Besides authentication, TACACS+ also allows us to configure authorization and accounting. Authorization lets us define what commands a user is able to use on the router or switch, and accounting lets us log whatever commands the user is typing.
Tac_plus is a TACACS+ daemon for Linux, It’s based on the original Cisco source code and works with a simple configuration file.
