I’ve been playing around a bit with podcast clients the last couple of days. I’ve been finding online news feeds for the onlineradiotv.com site and for many of those I have bash scripts to handle downloading or streaming the audio available from shortwave broadcasters. I did run across a few podcasts too though and thought it might be time to take another look at linux podcasting clients…
So for the past month and a half I’ve been puzzling over northcarolinagenealogy.net and it’s mysterious sudden disappearance from google. I mean… let’s see, there are a couple hundred posts there. It uses the same template as this and the South Carolina genealogy site do. Nothing really different than the South Carolina Genealogy site (more posts…?) I don’t have any links to “bad neighborhoods” that I can tell over there, but doing a site:northcarolinagenealogy.net search at either google.com or blogsearch.google.com turns up NOTHING. (While similar searches for southcarolinagenealogy.org or averyjparker.com turn up scads of pages, and a November search would show the same for northcarolinagenealgy.net)
The last time I used openvpn, it was version 1.x and only supported a single connection per running process. So, if you had a server that you wanted to support multiple clients connecting, you had to… have multiple ports open to the outside world (unless you did something VERY fancy), and had to have as many openvpn processes open and listening for connections, as you had clients you expected to connect. It wasn’t a pretty setup unless you had a small number (1-5) that you expected to connect. Fortunately that has changed with the 2.0 series of openvpn and it’s really matured as a vpn solution.
Dealing with text…. we’ve looked at a couple of basics on logging in and starting to use the command line and hopefully not feeling too helpless there… we’ve seen ways to navigate directories and how to find new commands and how to find out more about how to use them. Now it’s time to talk about how to manipulate (work with) text files. Most every important configuration file in linux is text based and editable from the command line. This can be a VERY good thing at times, or very intimidating if you’re not comfortable with a command line environment. It’s worth noting that you CAN edit configuration files with a graphical interface text editor….
Now that we’ve logged in and learned how to move from one directory to another (and find where we are if we get lost…) it’s probably time to start learning how to find out about other commands. Well, if you press tab at the command line you will likely see something that starts like this….
$
Display all 4601 possibilities? (y or n)
and if you answer with a “y” you will see a long list of programs that could be run. That’s not usually the best way to find a program though.
This is part two in a series of “how to use the command line in linux” style articles…. these are intended to be quite basic for those that have not used a command line before…. In part one we logged in (if necessary) and found out about the help command, navigated a bit with the arrows and exit -ed from our login. This time we’ll try to learn a bit more about dealing with files and navigating. In a graphical interface, if you browse files, you’re presented with a list of files and folders for a directory that you can scroll through and read at your leisure. In the command line we have to tell the computer to list the files and folders for the directory that we’re currently “in” to list those in linux, we use the ls command….
I know many people get intimidated with a black screen, white text and blinking cursor. No mouse, not knowing where to start…. well, I’m going to spend a bit of time in this article trying to help show you how to survive the command line in linux. For starters, don’t think that linux is a command line only operating system. In some installs, the administrator may not want a gui, but there are some VERY functional and full featured graphical interfaces for linux. For me though, if you know what you want to accomplish, the command line can be a much more efficient way to “get the job done” for many tasks.
I did an article a while back about cron and scheduling tasks in linux (I also mentioned kron which is a graphical interface for cron scheduling…). That works well and good for things that happen on a recurring basis, but the next question is what if I want to schedule a command (or series of commands) to happen once and not again? Well, to tell the truth I’ve used cron for this on occasion, being sure to revisit the crontab and remove the entry before it repeats again, but there is a better way. At.
This sounds like a serious vulnerability. The SecurityFix is reporting on a very serious vulnerability in AOL.
The problem affects AOL version 8.0, AOL version 8.0+, and AOL version 9.0 Classic.
The vulnerability could allow a remote attacker to take control of a users PC. Basically, all that would be needed is for the AOL user to visit a specially crafted web page.
The 2006 Winter Olympics are coming up. This time around, the olympics are being held in Turin, Italy. The official site can be found here. I can’t say that I’ve been a huge fan of the Olympics, but there are things that interest me. First is the security environment. Obviously the Olympics is a high-profile event and unfortunately has been the target of trouble before. I can’t help but have a concern (and prayer) that the security will be clamped down in such a way that all the events go off smoothly and that sport is the main story for their run. Of course, the next thing on my mind is the technology aspect…. from this announcement
