              Amiga Mosaic & WWW Frequently Asked Questions

1: What is Mosaic?

Mosaic is a client for the World Wide Web. The World Wide Web is a new
application on the Internet which allows pictures, sounds, animations to
be viewed from anywhere on the Internet. Amiga Mosaic (AMosaic) is
available from Aminet <ftp://aminet/comm/net/Mosaic1.2.1_AmiTCP.lha> and
the Amiga Mosaic site. <ftp://ftp.omnipresence.com/pub/amiga/> 

Mosaic can also be used to access FTP servers from a GUI front end, and to
access Gopher and many other services. The next release of Mosaic will
even allow you to connect to telnet services listed on WWW pages.  

---------------------------------------------------------------------------

2: What version of AmigaOS do I need?

AMosaic version 1.2 works with 2.x Amigas. You need AmigaOS 3.x to view
inlined images. Other versions (including 1.2.1) work only on AmigaOS 3.x.
 

---------------------------------------------------------------------------

3: Why does Amiga Mosaic not do inlined images in AmigaOS 2.x?

AMosaic uses 3.x's DataTypes system to display inlined images.  

---------------------------------------------------------------------------

4: What networking software do I need?

There are versions of AMosaic 1.2 for use with any of DNET, AmiTCP 3.0b2,
or AS225r2. Software derived from those two TCP/IP stacks or emulating it
can also be used. Later versions should all be available for either AmiTCP
3.0b2 or AS225r2.  

---------------------------------------------------------------------------

5: Amiga Mosaic keeps saying "failed to create application" when I try to
start it. Why?

Because you don't have MUI installed, or don't have a recent enough
version for Amiga Mosaic. Install the latest version.  

---------------------------------------------------------------------------

6: Why does AMosaic require MUI? I hate MUI!

We like MUI. It made creating AMosaic much easier for us.  

---------------------------------------------------------------------------

7: AMosaic crashes when I iconify it, or change the preferences using MUI
Prefs.

This is fixed in Amiga Mosaic 1.4 and later. If you can't run those
versions, then don't do that.  

---------------------------------------------------------------------------

8: Why doesn't Amiga Mosaic display external images?

Could be any number of reasons. First, make sure that you have an
env:mosaic/mailcap file. Next, make sure that there is an entry in it for
the type you are trying to display. Finallly, make sure that that entry
has a %s in the command.  

---------------------------------------------------------------------------

9: How do I use forms with Amiga Mosaic?

You have to use version 1.4 beta or later.  

---------------------------------------------------------------------------

10: How do I have Amiga Mosaic use a proxy server?

Set the environment variable for the protocol to the appropriate proxy.
For example, to cause HTTP request to go to www.hut.fi:8001, set
HTTP_PROXY to http://www.hut.fi:8001/. This only works with Amiga Mosaic
1.3 and above; previous versions use an obsolete proxy protocol.  

---------------------------------------------------------------------------

11: Why doesn't the NO_PROXY variable work?

Because it isn't implemented yet.  

---------------------------------------------------------------------------

12: I just get a window popped open on my screen when I tried to play at
an external sound/view an external image:
Title=AmiTCP:bin
Please send email to witbrock@cs.cmu.edu
telling him that you passed through the unsupported
pipe code and which URL it happened on. Also say:
file HTFWriter.c:HTSaveAndExecute line 461 compiled Jun 14 1994 20:07:49

The problem is that you removed the %s from the line handling audio in
your mailcap file. Amosaic is trying to pipe the audio to your player, but
it can't. You need to fix your mailcap file. 

This answer applies to non-audio data too, and to versions of mosaic more
recent than 1.3. As a side note, hours of fun can be had by turning up the
speakers loud and playing that URL with a cat in the room.  

---------------------------------------------------------------------------

13: How do I get Mosaic to open on it's own screen?

For MUI 2,3, run the MUI application, and take the following steps in it: 

1) Make sure you are on the "System" page.

2) Change application selector from "«Global»" to "AmigaMosaic".

3) Use the screen selector to create a new public screen for Mosaic.

4) Edit it as appropriate.

5) Exit MUI with the Save button. 

You may need to run and exit Amiga Mosaic before you can select it in the
application selector. 

For MUI 3.1, start with the MUI application, doing the folllowing: 

1) Go to the "Windows" page.

2) Click on the button closest to the "Gadgets:" label in the "Window
   Control" frame.

3) Save this 

Now, run Amiga Mosaic (or find it's window if it was running), and notice
that there's a gadget that looks like the one you just enabled in the MUI
application. Click on it, then click on the "Settings" item in the
resulting menu. It brings up what looks like the MUI preferences editor.
In that, do the following: 

1) Go to the "System" page.

2) Click the "Call Inspector" button in the "Public Screen" frame.

3) Set up the screen you want Amiga Mosaic to run on in the resulting
   requester, then save it.

4) Now, use the screen selector to select that screen.

5) Save the results. 

Amiga Mosaic should move to that screen.  

---------------------------------------------------------------------------

14: Is there going to be a commercial version of AMosaic?

Almost certainly not. AMosaic is a port of NCSA X Mosaic, and the right to
sell it commercially requires a rather expensive license. 

However, at least three different Amiga GUI web browsers are being written
from scratch. The group that did Amiga Mosaic is working on one of them,
and it will be commercial.  

---------------------------------------------------------------------------

15: Is the source to Amiga Mosaic available?

Yes, from  the Omnipresence FTP server
<ftp://www.omnipresence.com/pub/amiga/mosaic/MosaicSrc.lha>.  

---------------------------------------------------------------------------

16: How do I subscribe to the AMosaic mailing list?

Send the message "subscribe amosaic" to the address
"majordomo@omnipresence.com". Or, if you'd prefer to subscribe to the
digest version and get one combined message per night, send the message
"subscribe amosaic-digest" to the same address.  

---------------------------------------------------------------------------

17: Are there any other web browsers for the Amiga?

There are a number of other web browsers available. See the amiga browsers
page <http://www.phone.net/home/mwm/amiga-browsers.html> for a current
list.  

---------------------------------------------------------------------------

18: What other references might be useful?

[Authors note: I'm including both commercial and non-commercial
references, along with how to find either them or more information. This
is not an endorsement, merely a pointer to more information.] 

For a general discussion of AmiTCP issues, including application lists and
help getting started, see the AmiTCP FAQ.
<http://www.phone.net/ATCPFAQ/amitcp.html>  

Multilink (normally MLink) functions somewhat like TIA, but uses it's own
protocol with replacement stacks, with source available for the Unix end.
If you're considering TIA, you might want to look at the Multilink support
page. <http://www.hut.fi/~oahvenla/MLink/>

19: Can I set up a World Wide Web Server with AmiTCP?

Yes. You can find a copy of the Amiga Web Server (AWS) on the AWS site.
<ftp://ftp.omnipresence.com/pub/amiga/aws/>  

The other Amiga-native WWW server is awebserver, available from aminet.  

If you prefer the NCSA http daemon, Graham Walter did an excellent port.
It is available from the Amiga Mosaic site.
<ftp://ftp.omnipresence.com/pub/amiga/amosaic/>  

A more recent port of Apache - derived from the NCSA httpd - is also
available from Aminet.  

---------------------------------------------------------------------------

20: How do I keep inetd from saying that httpd is looping?

Inetd assumes that nobody would want to connect to a service more than 10
times a minute. For AmiTCP 3.0b2, this is hardwired into the code, and
cannot be changed without source. You can ftp a patched version of inetd
for AmiTCP 3.0b2. <ftp://ftp.phone.net/pub/mwm/> For AmiTCP
4.1 and later, you can use the TOOMANY option on inetd to change this from
the default value of 60 connections/minute.  

---------------------------------------------------------------------------
