Earlier today while working on a client’s server, which happens to be Microsoft Server 2003, I was unable to extract a .exe file from a zip file I had downloaded. After a moment of thinking I remembered that on Windows 2003 Server there is a default security setting that will simply not extract the .exe file. Below there are brief instructions on how to enable extracting a executable or .EXE file from a compressed zip file.
A couple days ago a CentOS Linux server that I took over administration on had some mysterious files show up in the /tmp and /var/tmp directories. The files were placed in /tmp and /var/tmp by the apache user meaning there is some form of security hole in Apache, PHP, or one of the virtual hosts has an insecure application installed. Before looking into where the issue is I needed to lock things down so no applications could be executed from these directories in the future regardless of a security flaw in the future. Below are instructions on how to secure /tmp and /var/tmp.
I was having a very slow morning at work and I started experimenting with sending tweets from the command line in Linux. I realize this is a little silly and there are plenty of good twitter apps out there but I found it amusing so I decided to post it.
A client of mine recently purchased a Panasonic DP-2330 Digital Imaging System. This device functions as a copier and a network printer which can output up to 23 color pages per minute. There are many features to the device that make it a great addition to any office that needs a centralized network printer.
I have installed the Panasonic DP-2330 on Windows Vista Business Edition (32-Bit/64-Bit), Windows XP Home Edition, and Windows XP Professional. This printer will not install automatically using the drivers that come with Windows so you are required to download the GDI printer driver from Panasonic. Use the information below to download and install the printer driver for the DP-2330.
Installing nmap security scanner on Windows XP is fairly easy. The easiest way is to download and run the nmap stable release executable file currently located here. You can verify the latest release by visiting nmap’s download page here.
Once the nmap.exe file is downloaded just double click it and choose a location to unpack the files. The easiest place would be something like c:\nmap or if you have cygwin installed you might want to do c:\cygwin\nmap. Make sure to note the location as you will need to add this to your path so you can execute it without having to be in the nmap directory.
