# Knowing Knoppix/Internet

# Common web browsers

Once you have an Internet connection, Knoppix has several different *web
browsers* built in. A web browser is a program for using the World Wide
Web, one of the Internet\'s most popular
services.

## Konqueror

Konqueror is a web browser and file manager, which uses the
KHTML layout engine to render content. The WebKit
layout engine used in Safari and Chrome browsers is based on KHTML.

When starting Knoppix for the first time or with default settings into
the K Desktop Environment (KDE), Konqueror will start automatically and
will display a local HTML page introducing Knoppix.

To invoke Konqueror later on in KDE, click Konqueror Web
Browser on the Panel.

## Gecko-based browsers

The Mozilla Application Suite,
then just known as Mozilla, has been a mainstay in earlier versions of
the Knoppix CD until Knoppix 3.8. Mozilla has not been included since
that version in favor of Mozilla Firefox. Mozilla and Firefox are both
available on the Knoppix 4.0 DVD.

### Mozilla Application Suite

Mozilla is a whole, integrated, configurable, sophisticated and
extensible Internet application suite. To invoke it in KDE, click the
"Mozilla Browser" button on the Panel.

On modern hardware, the Mozilla Web
Browser may take longer to start than
Konqueror in K Desktop Environment (KDE), because Konqueror and KDE
share the same toolkit and other technologies. On slower computers with
limited RAM memory, Mozilla may be more responsive when run from a
simple window manager and not from a desktop envrionment.

### Mozilla Firefox/IceWeasel

Mozilla Firefox, a fast, light browser,
replaced Mozilla proper. Firefox 1.0.3 was included in Knoppix 3.8.2 and
has remained the primary browser ever since. Unlike Mozilla, which is a
whole application suite, Firefox 1.0 had an advantage with speed and
responsiveness.

Mozilla Firefox 2.0 later turned out to be comparably less responsive
than SeaMonkey 1.x --- a fork and descendant of Mozilla, that was still
based on original Mozilla technologies, which had matured in 2001/2002.
Firefox 2.0 also requires more in-depth customization than SeaMonkey to
make it more responsive and less resource-hungry.

The Mozilla Firefox package was later changed to
IceWeasel, a version- and source-compatible
fork of Mozilla Firefox. The change was borne out of a naming and
trademark dispute with Mozilla.org and developers of Debian (on which
Knoppix is based).

Since at least Knoppix 6.0.1, IceWeasel has by default included the
NoScript extension, which protects against web
attacks.

## Small browsers

-   For a minimal web browser, click K menu -\> Internet -\>
    Dillo.
-   For text-only web browsing (yes, really), click K menu -\> Internet
    -\> Lynx. Then hit the letter G (for Go). You will be prompted to
    enter the web address that you want to visit. Type the web address
    that you want, then press Enter. The web page will be loaded.

# Email

Knoppix has several different *email clients*. An
email client is a program that lets you send and receive Internet email.
Here is how to set up the KMail email client in
Knoppix:

1.  Click the K menu in the bottom left corner.
2.  Point to "Internet".
3.  Click "*KMail* (Mail Client)".
4.  The KMail mail program will be loaded.
5.  Click the "Settings" menu.
6.  Click "Configure *KMail*".
7.  The KMail configuration screen will appear. On the left side, ensure
    that "Identities" is selected. Click "Modify".
8.  Enter your real name, organisation and email address, then click OK.
9.  Click "Network".
10. Click "Remove".
11. Click "Add".
12. Make sure "SMTP" is selected, then click OK.
13. In the "Host" box, enter the *hostname* of your Internet Service
    Provider\'s outgoing SMTP (Simple Mail Transfer
    Protocol) server. If
    the SMTP server requires authentication, check the "Server requires
    authentication" box and enter your username and password for sending
    mail.
14. Click OK.
15. Click the "Receiving" tab.
16. Click "Add".
17. Select the type of incoming mail server you have. Most Internet
    Service Providers use POP (Post Office
    Protocol). Some provide IMAP
    (Internet Message Application Protocol).
18. Click OK.
19. Enter your login and password for receiving your email. Enter the
    server which provides your incoming email in the "Host" box.
20. Click OK. This takes you back to the "Configure *KMail*" screen.
21. Click OK again.
22. To see if you have new mail, click the "File" menu, then "Check
    Mail". Or click the "Check Mail In" button on the toolbar. KMail
    will look for your new messages.
23. To write email, click the "Message" menu, then "New Message". Or
    click the "New Message" button on the Toolbar.
24. When you have finished writing, click the "Message" menu, then
    "Send". Or click the "Send" button in the Toolbar.

**`Important`**\
`Knoppix will not let you accidentally run Linux programs received by email.`\
`Program files must be given `*`execute permission`*` before they can be run by double-clicking on them.`\
`This gives excellent protection against would-be “email viruses”, while still letting you open ordinary document attachments easily.`
