While troubleshooting a programming problem today I noticed that you can’t use a LIKE search for string columns containing special characters like % or _ without using a special syntax. Figuring out the problem took only a few minutes, but remembering syntax is always easier if you write about it.

Has this ever happened to you? I created a new virtual machine running Ubuntu on my VMware server before I left home, but forgot to install the ssh server… so I couldn’t get to that machine at all from my remote location. Rather than driving back home I decided to find a solution.

One of the biggest security holes you could open on your server is to allow directly logging in as root through ssh, because any cracker can attempt to brute force your root password and potentially get access to your system if they can figure out your password.

I’m the type of geek that has an SSH client open at all times, connected to my most frequently used servers so that I have instant access for monitoring and anything else. As such, it irritates me greatly when I get disconnected, so I’m sharing a few methods for keeping your session alive.

Today a reader had a very good question about lsass.exe is the Microsoft security management process for domain access and local security policies.  Simply put it manages who logs on to your PC and/or Server.  There are a few viruses that mimic this process.  The Sasser virus was one of the more popular attacks a few years ago.  The Sasser worm would exploit lsass.exe so that XP would start a countdown of 60 seconds advising you to save your work.  Every time you rebooted your machine this would keep happening.  This process is located in C:WindowsSystem32 in either a PC or Server.  If you were to find it in any other location in your system … it is a virus.

I have been testing Windows Home Server (WHS) for about 6 months now. I thought I would write a few things about this new product from Microsoft. Basically, WHS is meant to be a computer which will sit in your closet and deliver multimedia content to various computers and other geek gadgets around your house. You are able to create user accounts, stream music and video, and create backups to your home server. Your children can watch a movie on their computer while you listen to your favorite music or vice versa. Saving copies of your files is just like you would do at work if you put them on a network drive.

So you’ve got MySQL on your web server, but it’s only opened to local ports by default for security reasons. If you want to access your database from a client tool like the MySQL Query Browser, normally you’d have to open up access from your local IP address… but that’s not nearly as secure.

My favorite feature in the latest version of VMware Workstation is that you can run virtual machines entirely in the background. This is most useful for “appliance” machines that you won’t actually use from the prompt, but through a web browser or ssh client.

A very common task for a web developer is uploading a single file from a subdirectory on your development box to the same subdirectory on a remote server. Unfortunately, this always ends up being an annoying manual process involving switching directories on both servers, and wastes a large amount of time.

As this site has gained popularity, the time required to keep the site running has also grown. For instance, even though Akismet blocks virtually all of the spam comments, I still have to manually filter through hundreds of spam comments per day to see if any valid comments were blocked.
