1. GENERAL INFORMATION
1.1) What is PPP
Non Technical
Point to Point Protocol (PPP) is a network protocol that can
turn your home PC into an Internet node via the phone line.
Technical
PPP is the Internet Standard for transmission of IP packets
over serial lines. PPP supports asynchronous and synchronous
1.2) Why do I need PPP
Using PPP give your computer the ability to browse the World Wide
Web (via Netscape or other browsers), FTP, telnet, IRC, and many
other internet related activities using your PC at home.
1.3) Why PPP instead of SLIP?
PPP is better than SLIP because it invokes more error checking
than SLIP.
1.4) What do I Need to use PPP
PC Requirements

2. PPP CONFIGURATION PARAMETERS
2.1) IP Addresses
Each port on the terminal server at RU has a different IP address.
Example:
Port 1 137.45.10.101
Port 2 137.45.10.102
Port 3 137.45.10.103
Port 4 137.45.10.104
Thus, your IP address will change each time you connect if you get
a different modem. Most packages will either automatically adapt to
this using ppp, or you can specify server assigned IP address.
2.2) DNS Servers
The following is a list of DNS servers available on campus.
137.45.128.132
137.45.128.4
137.45.192.100
2.3) Domain Suffix
runet.edu
2.4) Subnet Mask
255.255.255.0
2.5) Default Gateway
137.45.252.55
2.6) MTU Settings
Maximum Transmission Unit (MTU) refers to the size of an IP packet.
On the Radford University Terminal server, this value is currently
set to 1500.
1500
