Protecting your site from particular IP addresses w/ Apache
If a particular user is abusing your Apache web server, it is quite easy to deny access to your site. We found (with our ISP) that the easiest is to put an entry in the .htaccess file in the root of the directory you want to protect: deny from xxx.xxx.xxx.xxx Where xxx.xxx.xxx.xxx is the offending […]
Using Whois With PHP
If you would like to provide whois queries via PHP, a good package to use is available here. An example script that uses this package is: <?php include(“whois/main.whois”); $whois = new Whois($_GET[‘query’]); $result = $whois->Lookup(); echo “<pre>”; for($i=0;$i<count($result[rawdata]);$i++) { $row = each($result[rawdata]); echo $row[“value”].”\n”; } echo “</pre>”; ?> The query variable is arbitrary.

Adding PHP Support to Apache
Assuming that you have PHP installed, and the module available for Apache, these lines need to be in httpd.conf for PHP support: DirectoryIndex index.php index.html <Files *.php> SetOutputFilter PHP SetInputFilter PHP LimitRequestBody 10000000 </Files> AddType application/x-httpd-php .php Now, these lines are often in other files that are included; however, if .php pages just spew the […]

Adding Modules to httpd.conf With Apache 2
We recently converted from a source version of Apache 2 to an RPM version. We wanted all of the PHP/MySQL stuff compiled in and working quickly. Yes, we were very lazy.

Installing XAMPP on a Minimal System

Parsing Web Logs Into Calendar Text/Stats
We aren’t quite happy with the web stats software we use. The information is not brief enough. Mostly, we want to see the last couple months, with the weekends visible, and the unique hosts and pages viewed. Also, we have a lot of content that gets snagged that isn’t really what we consider a valid […]
