from one location. RADIUS prevents hackers from intercepting and 
responding to authentication requests by transmitting an authentication 
key that identifies it to the RADIUS client.
Characteristics
Protocol:  UDP
Server Port(s): 1645
Client Port(s): client
RIP
RIP is a routing protocol that predates IP, making it one of the oldest 
protocols on the Internet. It is used to automatically build routing tables 
for local routers. Because it is directionless, it is quite similar to DNS in 
configuration. You should enable RIP only if your Internet service 
provider requires that you run a routing daemon.
Incorrect or deceptive routing information can wreak havoc with local 
networks, could cause service denial problems, and possibly completely 
compromise the local network. Enable this service only after careful 
consideration.
Characteristics
Protocol:  UDP
Server Port(s): 520
Client Port(s): greater than 1023
SMB (Windows Networking)
Server Message Block (SMB) is used by Windows to share files, 
computers, printers, and other network resources.
If you set up replication, you may see repeated attempts to use the port 
mapper service on port 135. This will eventually fail, and fall back to 
using port 42. Refer to the RFC for DCE, and the DCE-RPC proxy sections 
for more details.
