<title>Connecting to and Using the Internet</title>

21

<para>The Internet is used daily by millions of people for work and entertainment. Searching for

22

information all over the world, corresponding with friends

23

and relatives, participating in discussion forums, reading the news, playing games,

24

has never been easier... or more accessible.</para>

25

<para>The means of connecting to the Internet is not always a choice and depends greatly on where you live and/or work

26

and the surrounding infrastructure. The pre-requisites to connect to the Internet are an Internet Service Provider (ISP) subscription and a functional Internet connection in your area.

27

Configuring the Internet connection requires minimal involvement from you. Ubuntu supports most connection types. This

28

lesson will cover: Broadband (cable or ASDL), dial-up and direct access through Local Area Network (LAN).</para>

29

30

<para>Broadband refers to either Asymmetric Digital Subscriber Line (ADSL) or a DOCSIS connection (television cable).</para>

31

<para>Ethernet Modem (PPPoE) uses a modem connected to the computer with an Ethernet network cable.

32

It is generally used in conjunction with Broadband connection.</para>

33

<para>Dial-up uses dial-up connection, and is limited to 56 kbit/s or slower.</para>

34

<para>Local Area Network (LAN) uses Ethernet or wireless, and is generally also used in conjunction with a Broadband connection.</para>

35

<para>Mobile Phone uses modem functionality integrated into modern mobile phones.</para></tip>

36

<para>Broadband connections are fast and reliable connections that users subscribe to

37

for a fixed monthly fee. Broadband companies offer packages with different speed

38

specifications and bandwidth limits. If you travel and need Internet access, you

39

can purchase a wireless Internet connection. If your computer does not have one pre-installed,

40

you will need to install a wireless card. This connection is similar to a satellite connection, where data is

41

transmitted through the airwaves.</para>

42

<para>Dial-up access uses the same lines as your phone connection, except that the parties at the two ends are computers. This is a slow and cheap connection

43

that uses a phone line to connect to a local server. Your computer dials a phone number that is provided by your ISP and

44

connects to the server. Consequently, you cannot make phone calls while you are connected to the Internet. This is oldest and slowest means of connecting; carrying out many functions

45

using this mode can be very tedious and frustrating.</para>

46

<sect2>

47

<title>Network Manager</title>

48

<para>The Network Manager on Ubuntu is a simple to use and powerful utility to stay connected with wired and wireless adapters. It is located on the top menubar at the outer right corner.

49

A left-click will reveal if your computer is already connected to a wired or wireless network. In case of a wireless network that is protected by a password, a dialogue will appear and ask for the password.

50

The password can then be stored in your keyring, where it will automatically be used when needed. However, you may be asked for your keyring password if you have to log out.</para>

open source drivers for these are not available. Therefore, these

<title>Accessing News</title>

359

<para>News can be retrieved from the Internet in different ways. Using Usenet and RSS for access is covered below.</para>

360

<para>Newsgroups are online notice boards where people post comments and discuss subjects of mutual interest. They are technically distinct from,

361

but functionally similar to discussion forums on the World Wide Web. Anyone can participate in the discussion and post thoughts. At the rate at which newsgroups

362

are growing, it is safe to say that there are groups covering most subjects imaginable; from computers to social issues, pet advice, literature and science,

363

job postings and housing to rent etc.

364

It is a fast and easy way to communicate, share views and advertise to people all over the world. Newsreaders are the applications used to access newsgroups.</para>

365

<para>USEr NETwork (Usenet) is the main source of newsgroups and newsfeeds. It is an Internet discussion system where people read and post e-mail-like

366

messages called posts to one or more of a number of newsgroups.</para>

367

<para>To join a newsgroup, you create a subscribed list and your newsreader stores the information. You will receive alerts when people have posted new listings

368

and when you check to read the latest update, there will be a posting and bunch of messages from several people. You will see something that looks similar to your e-mail inbox.

369

You can decide whether to reply to the newsgroup, the author or to both. Some people prefer not to constantly receive email messages and log in

370

from time to time to see the latest updates. The news server posts do expire after a certain length of time, as determined by the person running the server.</para>

371

<para>There are two types of newsreaders, online and offline. The online newsreader downloads just the message headers, and you see

372

what looks like a mailbox. The messages themselves however, are not on your machine. As you access a particular message,

373

the newsreader retrieves it from the server. When you are done reading a message, it is not stored on your machine,

374

unless you save it specifically. Offline newsreaders, on the other hand, connect to the server, download all new messages for the newsgroups to which you

375

are subscribed, upload any posts you wrote since the last time you connected to the server, and then disconnect. You can then read the messages as you

376

wish, composing replies and new posts to be uploaded next time you choose to connect. </para>

377

<para>Many news related Web sites do offer news feeds that allow you to see when Web sites have added new content.

378

You can get the latest headlines and video in one place, as soon as it is published, without having to visit the Websites you have taken the feed from.

379

Feeds, also known as Really Simple Syndication (RSS), are just Web pages.</para>

380

<para>In this section we will cover two types of Newsreaders, Linux Feed Reader (Liferea) for news feeds and Thunderbird for Usenet news.</para>

<title>Instant Messaging</title>

950

<para>E-mail message is not expected to be real-time, which means you can respond to it when time allows.

951

But when 'Immediacy' is required, instant messaging (IM) is the way to go. Using IM over the Internet

952

can bring down costs of long distance phone calls when you want to stay in contact with friends. While

953

in office, if you want an answer to a simple question, IM facilitates quick and easy communication and

954

reduces the amount of e-mail messages sent and received in a day. IM also enables you to view a person

955

using Web-cams or talk over the Internet for free.</para>

956

<para>The default instant messenger client on Ubuntu is Pidgin, a cross-platform instant messenger that

957

supports various popular IM network protocols. Using Pidgin, you can communicate with people who use America

958

Online (AOL) Instant Messenger (AIM/ICQ), Gadu-Gadu, GroupWise, IRC, Jabber, MSN, Napster and Yahoo. It

959

allows you to list all your friends in one window. Pidgin users can log on to multiple accounts on multiple IM networks simultaneously. This means that you can chat with friends on AIM, talk to a friend on Yahoo Messenger, and sit in an IRC channel, all at the same time. Pidgin supports many features of the various networks, such as file transfer, away messages, typing notification, and MSN window closing notification. A few popular features are Buddy Pounces, which give the ability to notify you, send a message, play a sound or run a programme when a specific buddy goes away, signs online or returns from idle.</para>

<title>Making Phone Calls Using Softphones</title>

1055

communication protocol and use a common audio codec to communicate with another person. The audio codec

1213

<para>Using Ekiga, you can call anyone who is registered to the public SIP provider and uses a SIP

1214

software or hardware. You can use the online address book of Ekiga to find the SIP addresses of other Ekiga users. It is of course possible to call users who are using another provider than ekiga.net. You can actually call any user using SIP software or hardware, registered to any public SIP provider. To make calls, you can type the Uniform Resource Locator (URL) address of the user you wish to call in the <emphasis role="strong">sip:</emphasis> input box and click the connect icon on the right of the text box to place a call. If you know the URL address of the party that you wish to call, you may enter that URL into the sip: input box at the top of the screen and press the Connect button. Pressing the Connect button would call the user at that address. With the default setup, you can simply type sip:foo to call user foo@ekiga.net.</para>

<para><emphasis role="strong">From Computer to Regular Phones</emphasis></para>

1216

<para>You can use Ekiga with multiple Internet Telephony Service Providers. There is a charge for this service so

1217

you will need to create an account with the provider first. You can then dial the numbers from the <emphasis role="strong">Dialpad</emphasis> and make

1218

calls.</para>

1222

select <emphasis role="strong">Use PC-To-Phone service</emphasis> and you are ready to call regular

1223

phones using Ekiga. With the default setup, you can simply use sip:00911129535955 to call the real phone number 003210444555, 00 is the international dialling code, 91 is the country code and 1129535955 is the number to call.</para>

1224

<para><emphasis role="strong">From Real Phones to Computer</emphasis></para>

1225

<para>You can also use Ekiga to receive incoming calls from regular phones. For this, you have to login

1226

to <emphasis role="strong">PC-To-Phone</emphasis> account and purchase a phone number. Ekiga then rings,

1227

when people call you at that phone number.</para>

a central server. To accomplish this, Skype uses a decentralized peer-to-peer technologies and its own

1299

proprietary communication protocol. Skype uses encrypted communication, which means all communications

1300

are encrypted from end-to-end so that others cannot listen in. We will not go into detail over Skype communication here.</para>

<title>Connecting to and Using the Internet</title>

47

48

<para>The Internet is used by millions of people daily for work and

49

entertainment. Searching for information all over the world, corresponding

50

with friends and relatives, participating in discussion forums, reading

51

the news, playing games, has never been easier... or more

52

accessible.</para>

53

54

<para>The means of connecting to the Internet is not always a choice and

55

depends greatly on where you live and/or work and the surrounding

56

infrastructure. The pre-requisites to connect to the Internet are an

57

Internet Service Provider (ISP) subscription and a functional Internet

58

connection in your area. Configuring the Internet connection requires

59

minimal involvement from you. Ubuntu supports most connection types. This

60

lesson will cover: Broadband (cable or ASDL), dial-up and direct access

61

through Local Area Network (LAN).</para>

62

63

<para>Broadband connections are fast and reliable connections that users

64

subscribe to for a monthly fee. Broadband companies offer packages with

65

different speed specifications and bandwidth limits. If you travel and

66

need Internet access, you can purchase a wireless Internet connection. If

67

your computer does not have one pre-installed, you will need to install a

68

wireless card. This connection is similar to a satellite connection, where

69

data is transmitted through the airwaves.</para>

70

71

<para>Dial-up access uses the same lines as your phone connection, except

72

that the parties at the two ends are computers. This is a slow and cheap

73

connection that uses a phone line to connect to a local server. Your

74

computer dials a phone number that is provided by your ISP and connects to

75

the server. Consequently, you cannot make phone calls while you are

76

connected to the Internet. This is the oldest and slowest means of

77

connecting; carrying out many functions using this mode can be very

78

tedious and frustrating.</para>

<sect2>

81

<title>Network Manager</title>

82

83

<para>The Network Manager on Ubuntu is a simple to use and powerful

84

utility to stay connected with wired and wireless adapters. It is

85

located on the top menubar at the outer right corner. A left-click will

86

reveal if your computer is already connected to a wired or wireless

87

network. In case of a wireless network that is protected by a password,

88

a dialogue will appear and ask for the password. The password can then

89

be stored in your keyring, where it will automatically be used when

90

needed. However, you may be asked for your keyring password if you have

91

to log out.</para>

which newsgroups are growing, it is safe to say that there are groups

669

covering most subjects imaginable; from computers to social issues, pet

670

advice, literature and science, job postings and housing to rent etc. It

671

is a fast and easy way to communicate, share views and advertise to people

672

all over the world. Newsreaders are the applications used to access

673

newsgroups.</para>

674

675

<para>USEr NETwork (Usenet) is the main source of newsgroups and

676

newsfeeds. It is an Internet discussion system where people read and post

677

e-mail-like messages called posts to one or more of a number of

678

newsgroups.</para>

679

680

<para>To join a newsgroup, you create a subscribed list and your

681

newsreader stores the information. You will receive alerts when people

682

have posted new listings and when you check to read the latest update,

683

there will be a posting and bunch of messages from several people. You

684

will see something that looks similar to your e-mail inbox. You can decide

685

whether to reply to the newsgroup, the author or to both. Some people

686

prefer not to constantly receive email messages and log in from time to

687

time to see the latest updates. The news server posts do expire after a

688

certain length of time, as determined by the person running the

689

server.</para>

690

691

<para>There are two types of newsreaders, online and offline. The online

692

newsreader downloads just the message headers, and you see what looks like

693

a mailbox. The messages themselves however, are not on your machine. As

694

you access a particular message, the newsreader retrieves it from the

695

server. When you are done reading a message, it is not stored on your

696

machine, unless you save it specifically. Offline newsreaders, on the

697

other hand, connect to the server, download all new messages for the

698

newsgroups to which you are subscribed, upload any posts you wrote since

699

the last time you connected to the server, and then disconnect. You can

700

then read the messages as you wish, composing replies and new posts to be

701

uploaded next time you choose to connect.</para>

702

703

<para>Many news related Web sites do offer news feeds that allow you to

704

see when Web sites have added new content. You can get the latest

705

headlines and video in one place, as soon as it is published, without

706

having to visit the Websites you have taken the feed from. Feeds, also

707

known as Really Simple Syndication (RSS), are just Web pages.</para>

<para>E-mail message is not expected to be real-time, which means you can

1826

respond to it when time allows. But when 'Immediacy' is required, instant

1827

messaging (IM) is the way to go. Using IM over the Internet can bring down

1828

costs of long distance phone calls when you want to stay in contact with

1829

friends. While in office, if you want an answer to a simple question, IM

1830

facilitates quick and easy communication and reduces the amount of e-mail

1831

messages sent and received in a day. IM also enables you to view a person

1832

using Web-cams or talk over the Internet for free.</para>

1833

1834

<para>The default instant messenger client on Ubuntu is Pidgin, a

1835

cross-platform instant messenger that supports various popular IM network

1836

protocols. Using Pidgin, you can communicate with people who use America

1837

Online (AOL) Instant Messenger (AIM/ICQ), Gadu-Gadu, GroupWise, IRC,

1838

Jabber, MSN, Napster and Yahoo. It allows you to list all your friends in

1839

one window. Pidgin users can log on to multiple accounts on multiple IM

1840

networks simultaneously. This means that you can chat with friends on AIM,

1841

talk to a friend on Yahoo Messenger, and sit in an IRC channel, all at the

1842

same time. Pidgin supports many features of the various networks, such as

1843

file transfer, away messages, typing notification, and MSN window closing

1844

notification. A few popular features are Buddy Pounces, which give the

1845

ability to notify you, send a message, play a sound or run a programme

1846

when a specific buddy goes away, signs online or returns from idle.</para>
