<h2>Introduction</h2> |
| 11 |
|
|
|
| 12 |
|
|
<p>News portal is a PHP based newsreader. It is licensed under the GNU |
| 13 |
|
|
Public License (see enclosed LICENSE). |
| 14 |
|
|
</p> |
| 15 |
|
|
|

|
|
<h2>Overview</h2> |
| 18 |
|
|
|
| 19 |
|
|
<p>This script collection enables the access to a newsserver (by NNTP) from |
| 20 |
|
|
a webpage. It allows you to combine web-forums and newsgroups. |
| 21 |
|
|
The script is also suitable for presentation of announce newsgroups |
| 22 |
|
|
on web pages, without having the user notice that he is in fact accessing a newsserver. |
| 23 |
|
|
</p> |
| 24 |
|
|
|
| 25 |
|
|
<p>The main functionality of the script is located in the file |
| 26 |
|
|
<tt>newsportal.php3</tt>, which contains the major part of the implemented php3-functions. |
| 27 |
|
|
In addition to that there are four more php3-files, which are directly accessed |
| 28 |
|
|
by the browser. |
| 29 |
|
|
<UL> |
| 30 |
|
|
<li><i>index.php3</i> shows the available newsgroups of the newsserver (if |
| 31 |
|
|
you have added the names to groups.txt) |
| 32 |
|
|
<li><i>thread.php3 </i>displays the article-overview of a newsgroup. The |
| 33 |
|
|
articles are displayed in a thread. |
| 34 |
|
|
|
| 35 |
|
|
<li><i>article.php3</i> displays an individual article. |
| 36 |
|
|
<li><i>post.php3</i> posts a message into a newsgroup. WARNING: This script |
| 37 |
|
|
produces absolutely not RFC conformal messages. Thus 'umlauts' in the Subject |
| 38 |
|
|
are not mime encoded ! It still works fine though. |
| 39 |
|
|
<li><i>config.inc </i> contains the configuration. |
| 40 |
|
|
<li><i>body.inc</i> contains the header and the body-tag of the pages. This way |
| 41 |
|
|
the layout of the pages (i.e. the background) can easily be adjusted. |
| 42 |
|
|
<li><i>german.lang </i>: The German language definitions |
| 43 |
|
|
<li><i>english.lang </i>: The English language definitions |
| 44 |
|
|
</ul></p> |
| 45 |
|
|
|
| 46 |
|
|
<p>Since fetching the article overview of the newsserver takes quite some time, |
| 47 |
|
|
newsportal caches this data in the directory |
| 48 |
|
|
<tt>spool/</tt>. Any file can be put in this directory, they will |
| 49 |
|
|
automatically be regenerated. |
| 50 |
|
|
</p> |
| 51 |
|
|
|
| 52 |
|
|
<h2>Installation:</h2> |
| 53 |
|
|
|
| 54 |
|
|
<p><ol> |
| 55 |
|
|
<li>download the zip or tar.gz archive |
| 56 |
|
|
<li>unzip it to a directory |
| 57 |
|
|
|
| 58 |
|
|
<li>The file<tt>config.inc</tt> |
| 59 |
|
|
must be edited with your settings (the most important variables are: |
| 60 |
|
|
<i>$server, $port, $title and $readonly</i>). |
| 61 |
|
|
|
| 62 |
|
|
<li>Write the names of all groups newsportal should show into the file <tt>groups.txt</tt>. |
| 63 |
|
|
Behind the groupname, seperated by a blank, a description of the group can be added. If the description is missing, |
| 64 |
|
|
newsportal will try to request the description from the newsserver. |
| 65 |
|
|
|
| 66 |
|
|
<li>The spool directory has to be created and configured to grant read an write access to the newsserver |
| 67 |
|
|
("chmod 777 spool" ). |
| 68 |
|
|
</ol></p> |
| 69 |
|
|
|
| 70 |
|
|
<h2>Configuration</h2> |
| 71 |
|
|
<p>The following adjustments can be made in <tt>config.inc</tt> |

<li><i>$file_newsportal="newsportal.php3":</i>Name of the file containing |
| 77 |
|
|
the newsportal-functions. |
| 78 |

<li><i>$file_groups="index.php3"</i>: The file which shows the list of |
| 79 |
|
|
available newsgroups. |

|
|
<li><i>$file_post="post.php3"</i>: The file which allows you to post an |
| 84 |
|
|
article to a newsgroup. This file can be removed, if the system is set on |
| 85 |
|
|
readonly (see below). |
| 86 |
|
|
<li><i>$file_language="english.lang"</i>: Reference to the language |

<p><b>Newsserver setip</b> |
| 93 |
|
|
<UL> |
| 94 |
|
|
<li><i>$server </i>: Hostname or IP of the newsserver |
| 95 |
|
|
<li><i>$port </i>: Port of the newsserver, normally 119 |
| 96 |
|
|
<li><i>$post_server</i>: Optionally an extra newsserver can be indicated here |
| 97 |
|
|
which is used by post.php3 for writing articles. |
| 98 |
|
|
This is useful if two newsservers need to be accessed, a fast read-only server and a slow server |
| 99 |
|
|
to post articles. Be aware that it might take some time until the posted article will show up on your |
| 100 |
|
|
main newsserver ($server), which you use to read articles. |
| 101 |
|
|
<li><i>$post_port </i>: Port of your post-newsserver |
| 102 |
|
|
<li><i>$server_auth_user</i>: If the newsserver requires authentication by name and password put your username |
| 103 |
|
|
here. Otherwise just set the variable to "". |
| 104 |
|
|
<li><i>$server_auth_pass</i>: Put your password here. |

<ul> |
| 111 |
|
|
<li>0: Simple listing of the articles</li> |
| 112 |

font face or size can be set.</li> |
| 123 |
|
|
<li><i>$thread_fontPost</i>: The same as $thread_fontPre, |

| 137 |
|
|
overview data of a newsgroup newsportal tries to get from the newsserver. |
| 138 |
|
|
"0" means no limitation. $maxarticles also indicates the amount of articles |
| 139 |
|
|
to be stored in the spoolfiles. A lower value means less work for newsportal</li> |
| 140 |
|
|
<li><i>$maxarticles_extra</i>: The problem with $maxarticles is that all |
| 141 |
|
|
article data must be completely requested again by the new server, if the |
| 142 |
|
|
indicated value is exceeded. |
| 143 |
|
|
$maxarticles_extra can be set to prevent this. |
| 144 |
|
|
The article-spool will only be restructured if |
| 145 |
|
|
$maxarticles + $maxarticles_extra articles are present, whereby |
| 146 |
|
|
$maxarticles many article data are requested. |
| 147 |
|
|
Only if an exact given number of articles should be displayed on the web page, the value of |
| 148 |
|
|
this variable schould be set "0".</li> |

|
n is a natural number > = 1 and all numbers from 1 to n must be |
| 154 |
|
|
assigned, gaps are not permitted.</li> |

|
|
<li><i>$age_color[n]</i>: The colour in which the article is marked</li> |

<li><i>$thread_sorting </i>: The sort sequence for the articles: |
| 157 |
|
|
<ul> |
| 158 |
|
|
<li>0: No assortment, articles are displayed in the order in which they are polled from |
| 159 |
|
|
the server. This is nearly like ascending |
| 160 |
|
|
assortment.</li> |
| 161 |
|
|
<li> 1: ascending assortment, the oldest articles to the top.</li> |
| 162 |

<li> -1: descending assortment, the newest articles to the top.</li> |
| 163 |
|
|
</ul></li> |
| 164 |
|
|
<li><i>$articles_per_page</i>: If this value is not 0, the maximum amount of articles is given, which are to be |
| 165 |
|
|
displayed on one page at the same time. The thread will be split into |
| 166 |
|
|
individual pages.</li> |
| 167 |
|
|
<li><i>$startpage</i>: In connection with $$articles_per_page |
| 168 |

|
the variable indicates, which page is to be displayed first: |
| 169 |

<p><b>Frame support</b><br> |
| 192 |

Example files for the frame support are located in |
| 193 |
|
|
<tt>extras/frames/</tt>. In this section the names of the frames can be |
| 194 |
|
|
defined. If you want to use frames you have to set the variable |
| 195 |
|
|
$frame_thread to "thread_frameset.php3". |
| 196 |
|
|
<ul> |
| 197 |

defined in <tt> thread_frameset.php3</tt>.</li> |
| 199 |
|
|
<li>$frame_thread</i>: Name of the thread frame. |
| 200 |
|
|
<li><i>$frame_groups</i>: Name of the frame for the grouplist, normally set |
| 201 |
|
|
to "_top" to open a new frameset.</li> |
| 202 |
|
|
<li><i>$frame_post </i>: Name of the frame for post.php3</li> |
| 203 |
|
|
<li><i>$frame_threadframeset </i>: Name of the frame, in which the |
| 204 |
|
|
frameset is to appear, which takes up the article and thread Frames. |
| 205 |
|
|
Normally set to "_top".</li> |
| 206 |
|
|
<li><i>$frame_externallink</i>: Target frame for external links within |
| 207 |
|
|
articles.</li> |

|
<p><b>Safety settings</b> |
| 211 |
|
|
<ul> |
| 212 |
|
|
<li><i>$send_poster_host</i>: "true" means that a header-line named "X-HTTP-Posting-Host:" |
| 213 |
|
|
will be attached to every posted article, set to the hostname of the user who wrote the article.</li> |
| 214 |
|
|
<li><i>$readonly </i>: if set to "true", the newsportal is read-only. The file post.php3 can be safely removed.</li> |
| 215 |
|
|
<li><i>$testgroup </i>: if set to "true" newsportal checks if a group is |
| 216 |
|
|
listed in <tt>groups.txt</tt> when accessed through thread.php3. |
| 217 |
|
|
Otherwise a group could be seen simply entering the right URL, although |
| 218 |
|
|
the group is not displayed in the group list.</li> |
| 219 |
|
|
<li><i>$validate_email </i>: Sets how newsportal checks an |
| 220 |
|
|
email address in post.php3 for syntax: |
| 221 |
|
|
<ul> |
| 222 |
|
|
<li>0: no examination. Not recommended, since the |
| 223 |
|
|
newsserver will give an error message, if the address is not syntactically |
| 224 |
|
|
correct.</li> |
| 225 |
|
|
<li>1: Checks the address on syntactic correctness.</li> |
| 226 |
|
|
<li>2: Additionally a MX or A record is checked for the domain-name of the e-mail address. |
| 227 |
|
|
Newsportal performs a hostname lookup.</li> |
| 228 |
|
|
</ul> |

<li><i>$title</i>: The value of this variable is put in the title-header of |
| 234 |
|
|
the generated webpages.</li> |
| 235 |
|
|
<li><i>$organization </i>: Name of your organization. Put after the |

email-address as cookies in his browser.</li> |
| 239 |
|
|
<li><i>$compress_spoolfiles</i>: Sets whether the spool files should be compressed or not. |
| 240 |
|
|
This is recommended under normal conditions, since the size of the spoolfiles shrinks |
| 241 |
|
|
approximately to about 15% of the original size. Be aware that some PHP-Versions |
| 242 |
|

<h2>Safety notes</h2> |
| 246 |
|
|
|
| 247 |
|
|
<p>A few things must be kept in mind to not allow newsportal to open |
| 248 |
|
|
safety-holes: |
| 249 |
|
|
<ul> |
| 250 |
|
|
<li><tt>config.inc</tt> can be requested by every user that knows the filename, |
| 251 |
|
|
if you do not move it to a protected area of your webserver. |
| 252 |
|
|
</ul></p> |
| 253 |
|
|
|
| 254 |
|
|
<p>This script was originally (and actually still) only meant |
| 255 |
|
|
for access to local newsgroups. If you use it with UseNet newsgroups, |
| 256 |
|
|
following problems could show up: |
| 257 |
|
|
<ul> |
| 258 |
|
|
<li>Articles could be posted anonymously (i.e. spamming), see $send_poster_host</li> |
| 259 |
|
|
<li>Newsportal produces 8-bit header lines (i.e. the Subject), |
| 260 |
|
|
which is not permitted. However there do not seem to be any problems.</li> |
| 261 |
|
|
<li>There are lists with so-called "open" newsservers in the |
| 262 |
|
|
internet. Mostly "open" doesn't mean for this server that everyone is |
| 263 |
|
|
allowed to use this server. Normally it means that the operator of the server |
| 264 |
|
|
forgot to protect his server adequatly. So before using an "open" newsserver, |
| 265 |
|
|
you should make sure that the operator permits the use of his |
| 266 |
|
|
server for newsportal.</li> |
| 267 |
|
|
<li>Posting articles anonymously is not accepted in most UseNet groups. |
| 268 |
|
|
Before you give writing access to a newsgroup, you should ask the users in the newsgroup |
| 269 |
|
|
if they have no objections. <b>Do not give public write access on UseNet newsgroups, |
| 270 |
|
|
if you do not know exactly, what you are doing!</b></li> |
| 271 |
|

<h2>Compatibility</h2> |
| 278 |
|
|
|
| 279 |
|
|
<p>Newsportal should work with every phpserver with php3 support |
| 280 |
|
|
and every newsserver. Webserver and newsserver do not need to run on the |
| 281 |
|
|
same machine.</p> |
