Rejected Urban Dictionary Words

Recently submitted a couple of words to Urban Dictionary but they rejected them. Anyway, here they are.

Whackamendation: Noun 1. The incorrect or undesireable result of an algorithm that the various social networking websites use to try and provide people you are not currently linked to on their site but might know based on your current network. 2. The incorrect result of the algorithm your DVR suggests you might like but is totally off-base and probably rooted in the one show you recorded by accident or error.

Fauxfile Pic: Noun 1. A picture a person uses on social networking sites to represent them that attempts to show them in a more socially-positive way. Examples of fauxfile pics are; a picture of the person that was taken over 5 years ago, a picture heavily corrected in digital imaging software such as Adobe Photoshop.

Unfortunately, UD seems to have gone downhill a bit.

More Complex GUI IPTables Setup for CentOS 5.x with Bastille Linux

We have a few CentOS boxes and require a little more IPTables tweaking than the standard security setup in the GUI. I could go into the IPTables config files, but I am more than a little rusty on the logic for IPTables. So, I went back to an old stand-by to config the multiple interfaces on a couple of my CentOS boxes.

http://bastille-linux.sourceforge.net

Download the RPM and install it.

sudo rpm -i Bastille-3.2.1-0.1.noarch.rpm

You can get perl-tk and and perl-curses via CPAN. I know DAG's RPMForge is just about standard now, but I prefer going to source if it is not standard. Of course, yum and the RPM model is basically kind of a pain now if you are used to apt-get in Debian/Ubuntu systems.I suppose the DAG RPMForge makes is a little less painful. But, CPAN is great.

You can do a couple of commands to get the pre-reqs for the graphical Bastille hardener. I would make sure you do these via the server console inside a gnome session. You get quite a site to watch on the Tk install.

sudo cpan install Tk

and

sudo cpan install Curses

I ended-up having to do a force install on Tk because I failed some of the TK install tests in the GUI. Anyway, no problem. This will get you what you need to then run

sudo bastille -x

I tend to run it via the console, but you should do it via ssh -X. Bastille comes in VERY handy when you have to do some IPTables configs for multiple network interfaces and you want different rules for different interfaces. Firestarter is another nice GUI tool when you don't want to get into tables configs yourself.

lickwh.at – The best URL Shortener Lick-Wilmerding Has Ever Seen!

Just launched a URL shortener service primarily useful for Lick-Wilmerding Alums, Students, Faculty and Staff.

http://lickwh.at

It is a play on the famous/infamous "Lick What?" saying seen around campus for years on sweatshirts and t-shirts. It is open to the public to use and would certainly be a little different than the other generic ones out there if you decided to use it. It is just a little side project, but fun to use so give it a try if you want.

Okay, I am now on Twitter


Okay, I am finally on Twitter now. I haven't ever seen a lot of value in it over the last couple of years for what I do, but now, there are a couple of good uses that make sense.

http://twitter.com/licktech is great for Lick-Wilmerding Technology updates. I think it will be usefull to provide status updates and downtimes as needed to those who care to know what we are doing behind the scenes. Traffic will be pretty high I think.

http://twitter.com/jonmergy is my personal account. Very low traffic.
