One Liner to Get External IP Address Comments Off

Was poking around ServerFault this morning and came across a great one-liner command using curl which will tell you the device’s external facing IP address. This probably isn’t anything new but it was something that I just haven’t thought of until now. curl icanhazip.com Icanhazip.com is just a simple output of the IP address of the accessor, so it is really clean and simple, just how I like it. It is really easy to set up by yourself if you have a domain not doing anything. In index.php, place: $ip=@$REMOTE_ADDR; echo "$ip";  

Copy Files to Many USB Drives Quickly and Easily 1

I was recently tasked with copying speaker’s presentations, files and handouts onto 100s of USB Drives (key drives) for a conference that work is hosting down in Washington, D.C. My first thought was that it was going to be a pain to have to copy/paste the files to each drive. I thought about creating a batch script to copy the files with a double click. But really, who wants to be doing all of that clicking and/or typing? Work smarter, not harder. Then I remembered a neat feature that SyncBackSE, a program I use at home for backups, has available. The backup program – which is basically a file copy process – can be triggered based on the insert of a drive, whether that be a USB Key Drive or an External Hard Drive. Using the program, the only action you need to do to trigger the copy process is….

Sensor Graphing via Wireless Sensor Network to a Mobile Internet Device Comments Off

I wrote this paper during this past spring semester at West Chester University, for a class in the Computer Science department. My paper was accepted and published in the proceedings of the 2009 International Conference on Wireless Networks which was held on July 13-16 in Las Vegas, NV. The title of the paper is “Sensor Graphing via Wireless Sensor Network to a Mobile Internet Device” – my demo device being the iPhone. The paper as presented is below: Sensor Graphing via Wireless Sensor Network to a Mobile Internet Device by David Drager

First Cell Phone SMS Vishing 1

Just received my first SMS “Vishing.” Vishing is where you receive a text message on your cell phone which tells you to call a number for some reason – your credit card was blocked, or something similar. The message I received was: 8665379776@suneast.org()SunEast F.C.U (Card Blocked) Alert. For more information please call 1-866-537-9776. Thank you./ The first tipoff for me was that I do not have a SunEast account. I called the number (which also appears to be associated with another business) and it just rang endlessly, so I am not sure if their system is working quite right; but I believe what is supposed to happen is that a voicemail picks up indicating that you should leave a message with some personal information – your banking password, credit card number, SSN, etc – which then the criminals can use to their advantage. Is this becoming more popular? This is….
