The phishers are getting techincal...
This morning I got a phishing letter. Since it was not from my bank, I almost deleted it without looking, and then this caught my eye:
You are receiving this message, due to you protection, Our Online Technical Security Service Foreign IP Spy recently detected that your online account was recently logged on from am 184.108.40.206 without am International Access Code (I.A.C) and from an unregistered computer, which was not verified by the Our Online Service Department.
Now, besides the bad English, which I will not take time to correct, the IP address jumped out at me and caught my attention and I had two immediate thoughts.
First, my thought was, as a normal Joe User, where is 220.127.116.11 and what does it mean I was logged in from there. That does not look like a street address. As an end user, I do not care what an IP address is (frankly, I do not care that I have one, much less know what it is), so does putting it in a phishing scheme make the email seem more legitimate? I would not think so, but then I have not bothered to study the science too closely.
But what intrigued me more, especially as a network engineer was that the 88 supernet, where ever it might be allocated, cannot possibly be exposing itself to the Internet, can it? And certainly not down to the host level? I cannot think of any major (or minor) corporation or ISP that does not do some form of address translation anymore, so how would I, as an end user, even know I was “logged on” from that IP address even if I was? My IP address is 10.x.x.x or 192.x.x.x or some other non-routable address. I would have no clue what IP address I am ultimately presenting to the outside world, so even if the letter was “legitimate,” giving me the IP address is pointless. Better to say I had logged on from a bistro in France.
But of course, that would defeat the purpose, and the purpose here is to scam you into clicking that little blue hyperlink and typing in your user name and password for the bad guys to get. The Internet never was the domain of fools but it has gotten more dangerous and less safe every day. Caveat emptor and lasciate ogni speranza voi ch'entrate (that’s Dante…)
Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
