In this article we will pass a parameter to a PHP script via a URL, and we will get a little more sophisticated in our conditionals and regular expressions. One problem with accepting parameters is that there are often security issues. It is very important to ensure that the parameters passed by the user conform […]

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 […]

Grab the sdk from java.com. For us, we are going to install this on Lobstora, which is a GNU/Linux box. Just make the binary executable and run it: [root@srv-1 opt]# chmod 700 j2*.bin [root@srv-1 opt]# ./j2sdk-1_4_2_03-linux-i586.bin We like putting this in /opt with a symlink to j2sdk. [root@srv-1 opt]# ln -s j2sdk1.4.2_03 j2sdk [root@srv-1 opt]# […]

SharePoint 2007 chooses a random port for administration. This is particularly difficult when choosing the single server configuration. Use the stsadm command to change the administration port number on MOSS 2007 / WSS 3.0. Go to this directory: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN> Enter this command: stsadm -o setadminport -port 4444 It will take […]

Rather than relying on the security provided by the default WordPress install, we have utilized some other security measures. We changed the prefix to the wordpress table names so zero-day SQL exploits which depend on default installations will not work. Defeating zero day exploits is significant because new WordPress vulnerabilities emerge often, and exploits may […]

Apache and some other programs need System V Inter-Process Communication (IPC) enabled in the Linux kernel. If you get this error when starting Apache: [emerg] (38)Function not implemented: Couldn’t create accept lock then it is possible that System V IPC is not enabled. If you are creating a custom Linux kernel, the option you want […]
