TCP/IP (Transmission Control Protocol/Internet Protocol)

TCP/IP is a protocol suite and related applications developed for the U.S. Department of Defense in

the 1970s and 1980s specifically to permit different types of computers to communicate and

exchange information with one another. TCP/IP is currently mandated as an of ficial U.S. Department

of Defense protocol and is also widely used in the UNIX community .

Before you install TCP/IP on your network, you need to establish your Internet addressing strategy.

First, choose a domain name for your company . A domain name is the unique Internet name, usually

the name of your business, that identifies your company. For example, Multi-Tech’ s domain name is

multitech.com (where .com indicates this is a commercial organization; .edu denotes educational

organizations, .gov denotes government organizations). Next, determine how many IP addresses

you’ll need. This depends on how many individual network segments you have, and how many

systems on each segment need to be connected to the Internet. You’ll need an IP address for each

network interface on each computer and hardware device.

IP addresses are 32 bits long and come in two types: network and host. Network addresses come in

five classes: A, B, C, D, and E. Each class of network address is allocated a certain number of host

addresses. For example, a class B network can have a maximum of 65,534 hosts, while a class C

network can have only 254. The class A and B addresses have been exhausted, and the class D and

E addresses are reserved for special use. Consequently , companies now seeking an Internet

connection are limited to class C addresses.

Early IP implementations ran on hosts commonly interconnected by Ethernet local area networks

(LAN). Every transmission on the LAN contains the local network, or medium access control (MAC),

address of the source and destination nodes. The MAC address is 48-bits in length and is non-

hierarchical; MAC addresses are never the same as IP addresses.

When a host needs to send a datagram to another host on the same network, the sending application

must know both the IP and MAC addresses of the intended receiver . Unfortunately, the IP process

may not know the MAC address of the receiver. The Address Resolution Protocol (ARP), described

in RFC 826 (located at ftp://ds.internic.net/rfc/rfc826.txt) provides a mechanism for a host to

determine a receiver’s MAC address from the IP address. In the process, the host sends an ARP

packet in a frame containing the MAC broadcast address; and then the ARP request advertises the

destination IP address and asks for the associated MAC address. The station on the LAN that

recognizes its own IP address will send an ARP response with its own MAC address. An ARP

message is carried directly in an IP datagram.

Other address resolution procedures have also been defined, including those which allow a diskless

processor to determine its IP address from its MAC address (Reverse ARP, or RARP), provides a

mapping between an IP address and a frame relay virtual circuit identifier (Inverse ARP, or InARP),

and provides a mapping between an IP address and ATM virtual path/channel identifiers (ATMARP).

The TCP/IP protocol suite comprises two protocols that correspond roughly to the OSI Transport and

Session Layers; these protocols are called the Transmission Control Protocol and the User Datagram

Protocol (UDP). Individual applications are referred to by a port identifier in TCP/UDP messages.

The port identifier and IP address together form a “socket”. Well-known port numbers on the server

side of a connection include 20 (FTP data transfer), 21 (FTP control), 23 (Telnet), 25 (SMTP), 43

(whois), 70 (Gopher), 79 (finger), and 80 (HTTP).

TCP, described in RFC 793 ( ftp://ds.internic.net/rfc/rfc793.txt) provides a virtual circuit (connection-

oriented) communication service across the network. TCP includes rules for formatting messages,

establishing and terminating virtual circuits, sequencing, flow control, and error correction. Most of

the applications in the TCP/IP suite operate over the “reliable” transport service provided by TCP.

UDP, described in RFC 768 (ftp://ds.internic.net/rfc/rfc768.txt) provides an end-to-end datagram

(connectionless) service. Some applications, such as those that involve a simple query and

response, are better suited to the datagram service of UDP because there is no time lost to virtual

circuit establishment and termination. UDP’s primary function is to add a port number to the IP

address to provide a socket for the application.

Chapter 1 - Introduction and Description

The Application Layer protocols are examples of common TCP/IP applications and utilities, which
include:

• T elnet (Telecommunication Network): a virtual terminal protocol allowing a user logged on to
one TCP/IP host to access other hosts on the network, described in RFC 854 ( ftp://
ds.internic.net/rfc/rfc854.txt).

• FTP: the File Transfer Protocol allows a user to transfer files between local and remote host
computers per IETF RFC 959 ( ftp://ds.internic.net/rfc/rfc959.txt).

• Archie: a utility that allows a user to search all registered anonymous FTP sites for files on a
specified topic.

• Gopher: a tool that allows users to search through data repositories using a menu-driven,
hierarchical interface, with links to other sites, per RFC 1436 ( ftp://ds.internic.net/rfc/
rfc1436.txt).

• SMTP: the Simple Mail Transfer Protocol is the standard protocol for the exchange of
electronic mail over the Internet, per IETF RFC 821 ( ftp://ds.internic.net/rfc/rfc821.txt).

• HTTP: the Hypertext Transfer Protocol is the basis for exchange of information over the
World Wide Web (WWW). Various versions of HTTP are in use over the Internet, with HTTP
version 1.0 (per RFC 1945) ( ftp://ds.internic.net/rfc/rfc1945.txt) being the most current.

• HTML: WWW pages are written in the Hypertext Markup Language (HTML), an ASCII-based,
platform-independent formatting language, per IETF RFC 1866 ( ftp://ds.internic.net/rfc/
rfc1866.txt).

• Finger: used to determine the status of other hosts and/or users, per IETF RFC 1288 ( ftp://
ds.internic.net/rfc/rfc1288.txt).

• POP: the Post Office Protocol defines a simple interface between a user’s mail reader
software and an electronic mail server; the current version is POP3, described in IETF RFC
1460 ( ftp://ds.internic.net/rfc/rfc1460.txt).

• DNS: the Domain Name System defines the structure of Internet names and their association
with IP addresses, as well as the association of mail, name, and other servers with domains.

• SNMP: the Simple Network Management Protocol defines procedures and management
information databases for managing TCP/IP-based network devices. SNMP, defined by RFC
1 157 ( ftp://ds.internic.net/rfc/rfc1157.txt) is widely deployed in local and wide area network.
SNMP V ersion 2 (SNMPv2), per RFC 1441< ftp://ds.internic.net/rfc/rfc1441.txt) adds security
mechanisms that are missing in SNMP, but is also more complex.

• Ping: a utility that allows a user at one system to determine the status of other hosts and the
latency in getting a message to that host. Ping uses ICMP Echo messages.

• Whois/NICNAME: Utilities that search databases for information about Internet domain and
domain contact information, per RFC 954 ( ftp://ds.internic.net/rfc/rfc954.txt).

• Traceroute: a tool that displays the route that packets will take when traveling to a remote
host.

Internet Protocol (IP)

IP is the Internet standard protocol that tracks Internetwork node addresses, routes outgoing
messages and recognizes incoming messages, allowing a message to cross multiple networks on
the way to its final destination. The IPv6 Control Protocol (IPV6CP) is responsible for configuring,
enabling, and disabling the IPv6 protocol modules on both ends of the point-to-point link. IPV6CP
uses the same packet exchange mechanism as the Link Control Protocol (LCP). IPV6CP packets are
not exchanged until PPP has reached the Network-Layer Protocol phase. IPV6CP packets received
before this phase is reached are silently discarded. (See also TCP/IP.)

Before you install TCP/IP on your network, you need to establish your Internet addressing strategy.
You first choose a domain name for your company. A domain name is the unique Internet name,
usually the name of your business, that identifies your company . For example, Multi-Tech’s domain
name is multitech.com (where .com indicates this is a commercial organization; .edu denotes
educational organizations, .gov denotes government organizations). Next, you determine how many
IP addresses you’ll need. This depends on how many individual network segments you have, and
how many systems on each segment need to be connected to the Internet. You need an IP address
for each network interface on each computer and hardware device.

IP addresses are 32 bits long and come in two types: network and host. Network addresses come in
five classes: A, B, C, D, and E. Each class of network address is allocated a certain number of host
addresses. For example, a class B network can have a maximum of 65,534 hosts, while a class C
network can have only 254. The class A and B addresses have been exhausted, and the class D and
E addresses are reserved for special use. Consequently , companies now seeking an Internet
connection are limited to class C addresses. The current demand for Internet connections will
exhaust the current stock of 32-bit IP addresses. In response, Internet architects have proposed the
next generation of IP addresses, Ipng (IP Next Generation). It will feature 16-byte addressing,
surpassing the capacities of 32-bit IP. Still in its design phase, IPng (also known as IPv6) is not
expected to be widely deployed before the end of this century .

An IP address can serve only a single physical network. Therefore, if your organization has multiple
physical networks, you must make them appear as one to external users. This is done via
“subnetting”, a complex procedure best left to ISPs and others experienced in IP addressing. Since
IP addresses and domain names have no inherent connection, they are mapped together in
databases stored on Domain Name Servers (DNS). If you decide to let an Internet Service Provider
(ISP) administer your DNS server, the ISP can assist you with the domain name and IP address
assignment necessary to configure your company’s site-specific system information. Domain names
and IP addresses are granted by the InterNIC. To check the availability of a specific name or to obtain
more information, call the InterNIC at [phone].

Front Panel

The front panel contains three groups of LEDs that provide the status of the LAN connection, link
activity, and general status of the ProxyServer. The EtherNet LAN LEDs display the activity of the
LAN in whether the ProxyServer is connected to the LAN, transmitting or receiving packets, and if a
collision is in progress. The Link LEDs display the status of the three links that can be connected to
the ProxyServer with whether a link is ready to transmit or receive serial data, and if an external
communications device with a V.35 interface is connected to the ProxyServer. The last group of
LEDs indicate whether the self test passed or failed and if the power On/Off switch on the back of the
ProxyServer is turned On.

Chapter 4 - ProxyServer Software

ProxyServer User Guide

Introduction

This chapter describes the ProxyServer 200-Series Proxy Server software package which is
designed for the Microsoft ® Windows ® environment. The Proxy Server Program Group has five
icons that allow you to configure your Proxy Server, download a default setup or firmware update,or
configure a local port from the Program Manager by double clicking on one of the icons.

Two levels of describing the Proxy Server software are provided; the Help screens contained in the
application provide the first level which is to define the options in a dialog box, the second level define
a task and how the dialog boxes need to be setup to perform that task. For example, in the IP Setup
dialog box, the LAN IP Address must be a static address that is assigned by the LAN Administrator.
This address must be unique to your LAN. This information is provided in the on-line Help. Now , the
task of assigning an LAN IP Address is described in this User Guide and covers the dif ference
between a static IP Address and a dynamic IP Address assigned by your local ISP as the port is
activated. The task approach in this User Guide is going to assume that you have access to the
Helps and therefore will not go into defining options or buttons within a dialog box, but more into the
task that need to be performed.

Before You Begin

Before you begin, let’s cover a few procedural matters so that they are out of the way.
To view or change your ProxyServer configuration, double click on the Proxy Server Configuration

icon.
You may also start Proxy Server Configuration from the File Manager by selecting the Proxy directory

and double clicking on the roucon.exe program in the file list. Local port setup can also be started
from File Manager by selecting psetup.exe from the file list.

You may also run Proxy Server Configuration from either the Program Manager or the File Manager
by clicking on the Run command in the File Menu, then typing: C:\ proxy\ roucon.exe in the
Command Line field. Local port setup can also be run from the Command Line by typing: C:\ proxy\
psetup.exe.

Setup Menu

The Proxy Server Setup menu organizes your configuration process into two categories: Stacks and
Drivers, and Other Setup. The Stacks and Drivers define the Proxy Server IP Protocol stack and the
device drivers define how the WAN is used, i.e., Point-to-Point Protocol (PPP), MultiLink PPP,
(MLPPP), or Serial Line IP Protocol (SLIP) .

The other Setup group defines the proxied applications, the Dynamic Host Configuration Protocol
(DHCP) for assigning IP parameters to the workstations on the LAN, applications such as TFTP for
transferring files between two nodes, telnet for terminal emulation at a remote workstation, and
filtering of data packets for getting through the link.

Chapter 4 - ProxyServer Software

Certain options are enabled depending on the state of the target. If no ProxyServer (target) is found,
click on the Configuration Port Setup icon in the ProxyServer program group, specify the right local
port parameters and retry running this application. You can also connect to the target through a dialup
modem.

ProxyServer setup also has a console terminal for displaying various debugging messages output
from the target. You can control the display of these messages using this application. Normally you
should turn off the display of all messages for better performance of the router .
