Introduction, Getting to know the Computer Pool
WWW: Basics, Internet-Search, Interesting addresses
(www.greenpeace.org,
www.nato.int, www.army.mil, www.whitehouse.gov, www.harvard.edu,
www.uni-mainz.de).
Commands (DOS-Box):
- ipconfig - to find out IP number of the computer
- tracert - for example "tracert www.nato.int" - find
out the network hops between the computers
- ping - for
example ping 172.17.10.230 -
or exercise: Ping your neighbour's computer. ping sends packets and if they are
received, the network connection is OK
IP-Number: Combined from four numbers, each from 1 to 255, example:
172.17.10.230
FQDN: Fully qualified domain name, for example: www.nmmu.ac.za
DNS: Domain Name System: transforms FQDN to IP-Number

Overview: How HTTP works. Important tags of HTML
Installation of the server used for our Online Surveys
(address:
umfragen.sowi.uni-mainz.de): Debian GNU/Linux
3.0r1
Woody (seven CDs), Pentium III / 256 MB RAM / 20 GB Harddisk.
Necessary steps:
1) Description of BIOS / BIOS-Settings / Harddisk recording
2) Partitioning the Harddisk (512 MB Swap), rest ReiserFS and
mount to root-directory /
3) Installation of the needed packages plus Proftpd, Apache
4) Setting the Root-Password und User-accounts of course members
5) Testing the WWW-Server und analysis of the corresponding logfiles
(/var/log/apache/access.log and error.log)
6) Create a simple homepage and transfer it to the server using the ftp
program
7) Try to create a simple Mail-Survey and store it on the server
8) Introduction to some additional knowledge for Online Surveys and
RST: Perl, Unix, access rights, reading and interpreting log files etc.
Because of the firewall we do not have access to the WWW-Server in
Germany. So we use a Debian GN/Linux Notebook instead. IP-number:
10.21.6.189
- Going to the page www.hinner.com/nmmu actually loads the
"index.html" file of this directory, so the file
www.hinner.com/nmmu/index.html is fetched by your Web-Browser (Internet
Explorer) and displayed.
- Select "View/Source" to get the html-file displayed. Go
through the tags and see how the structure of an HTML file is. Tags
inbetween <>, ending tags with heading "/"
- Note the most important tags: <head>, <body>,
<title>, <p>, <a>, <table>
- Online surveys basis: the <form> tag
- Open MS Frontpage and create your own first WWW-page (try
to create something useful, also include a form if possible)
- Transfer your "homepage" to the server (10.21.6.189) using
ftp. Open a DOS-Command bos (Start/Run/"cmd"), type ftp 10.21.6.189,
enter Username and password as told in the course. Change your local
directory to where your html-file is using the "lcd" command. Find out
in which directory you are using the "pwd" (print working directory) or
the "!cd" command. List local files with "!dir". List remote files with
"dir" or "ls -la". Transfer files to the server with the "put" command,
receive them with the "get" command. Transfer a couple of files with
mget or mput, for example: mput *.jpg - you will be asked for the files
to be transferred. Answer with "yes" or "no". You can disable those
questions with the "prompt" command. To transfer binary files (images,
programs) switch to "binary" mode first. To transfer html-files or
ASCII-text-files, first type "ascii" to switch mode Leave the
ftp-program with the "bye" command. While in the ftp-program, you can
re-logon with the "user" command, i.e.: "user khh" if the password was
wrong.
- Check in the WWW-browser if your files are there. Be aware
that the old file can be stored somewhere in a cache or proxy-Server in
between, so force Re-Loading of the file with "f5" or "View/Reload".
Task until 18.10.2005: Think and decide upon the three possible topics
for our example survey:
- HIV/AIDS
- The transformation process in South Africa compared to
German Unification
- How the Internet Infrastructure can be
improved in Sub-Saharan-Africa, also means finding the obstacles
- Student lifestyles: Comparison between P.E. students and
Mainz students

Task: Search the
internet and select one Online Survey, copy screenshots
in MS-Word and give a short commentary about content,
level of professionality (from the perspective of the social scientist)
- Decision about sample survey: Student lifestyle comparison
- The "form" tag - Designing a example survey with MS
Frontpage and transferring it to the server.
To do until 25.10.2005:
- Literature search of social scientist´s contributions
to Online Surveys - select one article, read it and evaluate it (must
be a paper article, not online).
- Find a program to conduct Online Surveys - if you found it,
read the instructions and what is needed to set it up and get it
running. Write your opinion.
- Create in Word or Powerpoint (or if you dare HTML) an
Online Survey with five questions (and given answers, if needed) to our
topic (student lifestyle comparison)

| 25.10.2005 |
- The firewall is now disabled so you have full ftp/telnet
access to the server "umfragen.sowi.uni-mainz.de" from NMMU campus.
Please put your sample survey inside your account on that server, the
login is your first name, password has been E-Mailed to you.
- Viewing homework: student lifestyle comparison surveys
Online Survey
programs, literature of social scientists covering this topic
- Working through and analysing the Survey-Sendmail-Programs
(Perl or PHP)
- Installation of RST
- Taking care and Installation of the needed Perl-Modules
(dselect)
- Getting orientation with error output in WWW-Server Log
(view with tail
/var/log/apache/error.log)
- RST: Presentation - Adapting an existing survey
- RST: Installation or adapting of course members' surveys
- RST: Adapting every survey of course members (that means:
Online Surveys of all couse members are running using the correct
account and with RST)
- Using RST and Cascading Style Sheets (CSS)
- Refining and "polishing" the surveys
