Website Security Tip remove catch all bindings

May 23, 2010 by Paul White

A few months ago I noticed that one of my clients websites seemed to be getting spikes of traffic.  However with spikes in traffic most clients would report an increase in sales or business.  When looking at the stats server, the requests were for pages and files that were not even on the server, and were for technologies ( PHP ) that I do not run on m box.  If you see requests for files like /prx2.php, /phpmyadmin/config/config.inc.php, /roundcubemail/readme, or /webmail/readme.  You might want to read this article.

Force Windows 7 to open excel documents in separate windows

Force Windows 7 to open excel documents in separate windows

Feb 11, 2010 by Paul White

I love windows 7, but I hate the way they open documents under a single window.  I googled for a long time to find a fix for this.  Finally I found the solution.  If you want to force Windows 7 to open your Applications especially Excel, Word, Internet Explorer, Firefox in a new window, then I have the solution. Get ready to make a simple Registry Edit to make windows the way run more like it used to under XP

Adaptec 4805 SAS RAID benchmark on Windows 7 review

Adaptec 4805 SAS RAID benchmark on Windows 7 review

Feb 5, 2010 by Paul White

I knew I was going to make the switch to Windows 7, but I wanted to make a few upgrades before I did this.  These upgrades included hot swap trays for my SATA drives, and extending my SAS RAID array from 2 drives to 4 drives.  However this forced me to get a Dedicated RAID controller, as the ASUS board only supports two SAS drives.  On this blog I will focus on the SAS RAID upgrade using the Adaptec 4805SAS RAID card and 4 x 15K RPM Fujitsu SAS Hard Drives.

Windows 7Every since the release of Windows 7 my friends have been urging me to make the switch.  They said its faster, and overall better.  Finally after getting ahead of some of my work I took the plunge and made the switch to windows 7.  Probably one of the best decisions I have ever made. If you want to cut your utility bill, I highly suggest you make the switch to windows 7.

Hacker Attacks and Invalid character in a Base-64 string

Jan 13, 2010 by Paul White

On my websites I have them setup to email me anytime a server error happens.  If you ever get an error like "Invalid character in a Base-64 string",  This is likely a hacker attack.   In my case it was on the members login on my client's website.  I logged in and shut down the site.  10 minutes later I started it back up and the hacker had left.  Interesting is what the HTTP RAW data reveled.

HTTP_X_FORWARDED_FOR:84.0.182.175, 84.0.162.91, 84.0.237.176, 84.0.228.6, 84.0.220.100, 84.0.147.233, 84.0.159.1, 84.0.84.37 HTTP_PROXY_CLIENT_IP:84.0.182.175, 84.0.162.91, 84.0.237.176, 84.0.228.6, 84.0.220.100, 84.0.147.233, 84.0.159.1, 84.0.84.37 HTTP_CLIENT_IP:84.0.182.175, 84.0.162.91, 84.0.237.176, 84.0.228.6, 84.0.220.100, 84.0.147.233, 84.0.159.1, 84.0.84.37

Never seen these values before.  According to the logs the IPs were from hundreds of compromised systems. However they all had these values in common.   I am going to add a rule to detect the Class A IP in the 80.x.x.x block in the HTTP_X_FORWARDED_FOR, and block.  Hopefully this helps some other people out

MX records being used to block spam

Apr 20, 2009 by Paul White

Recently I have noticed that the open rates of a few of my client's newsletters are going down.  This is leading me to believe that most free mail servers are using yet another litmus test to detect and block spam.  Unfortunately those of us with legit bulk emails campaigns are also feeling the pinch.

Dell Poweredge 1750If you have ever run into the problem of buying or selling something on ebay, only to have it not work once it reaches it destination, you know the kind stress this creates.  Basically the Dell Poweredge 1750 Server I had was not booting up, and would flash an orange / amber light on the front, and had no display, and no beeps.  The solution was pretty simple, Reseat everything!

Dec 17, 2008 by Paul White

Task Manager at 100 percent on core i7Now that you have your awesome new core i7 workstation ( like me ), its a shame that whenever you look at task manager you rarely see your 8 processing threads being utilized.  Well if you are one of those people that prefer your 4 cores not being hanging around the water cooler all day ( System Idle Process ). Then I have just the program for you.  Help in the Search for Extraterrestrial Intelligence ( SETI )
