KwikiExperiences

This Kwiki runs under the ?WN Webserver http:/docs/wn/manual.html. Here you will find out, how this works.

Look also at ?KwikiNotOnApache to see why one would do this and at ?FhsKwiki about some experimental code.

Authentication

Kwiki needs the webserver to be able to restrict access to one (1) file via authentication. I guess there are only a small number of Webserver which can do this, of course Apache can, but WN only can do authentication based on directories.

So the basic trick is, to move the admin.cgi of Kwiki to a subdirectory (called /admin/ here) and restrict access to this directory. admin.cgi calls are redirected to this directory. The admin.cgi accesses the original database, templates, etc. via symbolic links to the original places.

here is the output of ls -l of the normal instalation directory, showing the additional /admin/" directory, and a modified admin.cgi:

 drwxr-sr-x    2 root     root          320 Sep 16 00:44 admin
 -rwxr-xr-x    1 root     root          316 Sep 16 16:13 admin.cgi
 -rwxr-xr-x    1 root     www-data      103 Sep  5 14:36 blog.cgi
 -rw-rw-rw-    1 root     www-data     1304 Sep  9 11:09 config.yaml
 drwxr-xr-x    2 root     www-data      144 Sep  5 14:38 css
 drwxrwxrwx    2 root     www-data      944 Sep 16 16:15 database
 -rw-r--r--    1 root     www-data      394 Sep 16 00:38 index.cache
 -rwxr-xr-x    1 root     www-data       91 Sep  5 14:36 index.cgi
 -rw-r--r--    1 root     www-data      127 Sep 16 00:38 index.wn
 drwxr-xr-x    2 root     www-data      224 Sep  5 14:38 javascript
 -rwxr-xr-x    1 root     www-data       91 Sep  5 14:36 kwiki.cgi
 drwxrwsrwx    8 root     www-data      200 Sep 16 16:01 metabase
 -rwxr-xr-x    1 root     www-data       98 Sep  5 14:36 pages.cgi
 drwxr-xr-x    2 root     www-data      536 Sep  5 14:38 template

And here the contents of the /admin/ directoy. The real admin.cgi is copied here:

 -rwxr-xr-x    1 root     www-data      139 Sep  5 14:36 admin.cgi
 lrwxrwxrwx    1 root     root           14 Sep 16 00:36 config.yaml  -> ../config.yaml 
 lrwxrwxrwx    1 root     root            6 Sep 16 00:36 css ->  ../css
 lrwxrwxrwx    1 root     root           11 Sep 16 00:36 database -> ../database
 -rw-r--r--    1 root     www-data      529 Sep 16 00:37 index.cache
 -rw-r--r--    1 root     www-data      299 Sep 16 00:37 index.wn
 lrwxrwxrwx    1 root     root           13 Sep 16 00:36 javascript -> ../javascript
 lrwxrwxrwx    1 root     root           11 Sep 16 00:36 metabase -> ../metabase
 lrwxrwxrwx    1 root     root           11 Sep 16 00:36 template -> ../template
 -rw-r--r--    1 root     root           39 Sep 16 00:44 wnpasswd

And at last, the modified admin.cgi in the main directory:

 #!/bin/sh
 echo "\
 Content-type: text/html
 Location: http://www.magma.com.ni/im2000/admin/admin.cgi?$QUERY_STRING

 <HTML>
 <HEAD><TITLE>Wiki Administration</title></head>
 <BODY>
    <H1>Please go to the ...</h1>
    <A HREF="admin/admin.cgi?$QUERY_STRING">administration directory</a>
    of this KWiki
 </body></html>
 "

This makes for a redirection to the real admin.cgi located in the /admin/ subdirectory. There might be Browsers which do not understand the redirection, so the cgi also creates a page, showing a link to the real admin.cgi to click on.

WN Configuration

index.wn in the main directory:

 Default-Attributes=cgi

 Default-Document=index.cgi

 File=admin.cgi
 File=blog.cgi
 File=index.cgi
 File=kwiki.cgi
 File=pages.cgi

index.wn in the admin directory:

 Default-Document=admin.cgi

 Authorization-Module=~/cgi-bin/wn/wnauth wnpasswd
 Authorization-Realm=Wiki@magma.com.ni
 Authorization-Type=basic

 File=admin.cgi


 File=blog.cgi
 Redirect=../blog.cgi

 File=index.cgi
 Redirect=../

 File=kwiki.cgi
 Redirect=../kwiki.cgi

 File=pages.cgi
 Redirect=../pages.cgi

Kwiki Installation

I experienced some trouble when activating the features of Kwiki, here are the tips to avoid them:

Don't use any TAB Characters in the config.yaml file!

The following directories had to be created by hand

* metabase/blog

metabase/private
metabase/public
metabase/rcs

I gave this directories the following owner: chown root.www-data metabase/*
and permissions: chmod u=rwx,g=srwx metabase/*

Issues

The given configuration does not allow to see slides from within the admin directory.
