Basic Installation of TripWire

I originally posted this at

To install Tripwire, run in the folder that you have extracted the tripwire files into
sudo ./
Then enter passphrases/passwords when asked
Then enter the shortname of the primary user of tripwire
Allow the system to define the baseline state of the Server.

To update your tripwire database after making system changes run this command:
./tripwire -m u -r ../report/day-month-year-initials.twr

To update your tripwire config, change the /usr/local/etc/twcfg.txt file and run this command
./twadmin -m F -S ../key/site.key ../../etc/twcfg.txt

To enforce a new policy, edit the /usr/local/tripwire/policy/twpol.txt file and run this command:
./twadmin -m p > ../policy/twpol.txt

To view Tripwire reports run this command
./twprint -m r -r ../report/*.twr â†’ the * in this command is meant to demote your latest twr file

To scan what changes have been made to the system, cd into this directory /usr/local/tripwire/bin and run
./tripwire -m c
To email these changes to the email address listed in the config file, run ./tripwire –m c -M

Keyboard Shortcuts: Windows

10 Essential Keyboard Shortcuts for Microsoft Windows Users to Get More from their PCs

Keyboards: We all use them. Those of us that work for Three18 happen to use ours for anywhere between 6 and 18 hours a day, hopefully not more. With that kind of time, we’ve learned to be especially crafty in our pursuit to be as efficient as possible. We don’t know all the keyboard shortcuts, but we do know a bunch. Here are a few shortcuts that will have you keyboard jockeying like a pro in no time.

10 & 9: Ctrl-Tab and Alt-Tab. These 2 gems will cycle you through tabs in a window and through all open windows, respectively.

8: Ctrl-Alt-Delete. This well known keystroke combination will give you access to a plethora of information about your computer. Your task manager, current login, change password dialogue, are just a few. Explore this one, there’s more here than you think.

7: Just type! In any explorer window, or open folder you can jump to the file you’re looking for without using the scroll bars or buttons. It’s far more efficient than the scroll and read technique, just type the first few letters and you’ll jump right to it.

6: Windows-r: This combination will have the same effect as Clicking ‘Start’ and ‘Run’, leaving you with an open Run dialogue.

5: Alt-Enter: Instead of Right-clicking and choosing ‘Properties’, use this. It’s especially handy if you already have your right hand on the keyboard. Perhaps because you just used tip #7?

4: Hold Shift while inserting a CD/DVD: Need something off a disc, but don’t want to wait for the autoplay? Hold shift, and it will disable autoplay while mounting the disc.

3: Esc: In almost any window that has a ‘Cancel’ button, Esc is mapped to it.

2: Windows-m: If you’ve used a Mac for any length of time, you’ve probably used the Apple-H command to hide all windows. Here’s your Windows equivalent.

1: Hold Shift while closing a window: Open folders cascading out of control? The keystroke Alt-Shift-F4 or just holding Shift and clicking on the X to close your current window will also close all its parent windows.

Windows XP

Starting Windows in Safe Mode

For computers with one operating system installed, you can boot into safe mode, which Windows with a limited set of files and drivers and disables startup programs. This is pretty helpful when troubleshooting Windows problems. To start into safe mode, hold the F8 key down while rebooting a Windows computer. If you see the Windows logo appears, reboot and try again.

This should load the Advanced Boot Options screen. Here, use the arrow keys to highlight safe mode option and then Enter. That’s it. Hope this helps!

Positional Parameters and Packaging

When packaging it is worth note that Apple reserves some positional paremeters for your scripts. These are defined at

They include:

  • $1: Path to the package
  • $2: Path to the destination.
  • $3: Installation volume.
  • $4: Root directory
Mac OS X

Click on App, Hide Others

When you open an application you can have all the other applications minimize. To do so you’ll add the single-app key into by using the following command:

defaults write single-app -bool TRUE

Then you’ll need to restart the Dock:

killall Dock

Edge Family Gifting

You see, in my family it can get hard to buy good gifts for each other.  After my first book came out my dad decided that I needed a website.  So for my birthday he was kind enough to build me one in Flash.  Now that’s some serious Edge family gifting:

On the Road

On the Road: Pittsburg

One city that struck me as totally different than what I thought it would be is Pittsburg.  I expected a run-down, dirty city.  But it isn’t.  It’s really modern and nice.  :)
