Vandals caught on camera

2014.08.24

The kids in these two pictures punctured a hole in my cars front left tire and then rang out doorbell at 3:20 am on August 24, 2014.

My son and I were set for a early start to make an amusement park a few hours away. We still made the amusement park after filing our report with the sheriff. Vandalism to the car costs me time and money to repair. Taking time from an adventure with my son is unacceptable and the juveniles will be found.

I’ll be distributing the photos and information to the local middle schools.

Mac OSX applications won’t start after cloning or time machine restore

2012.06.20

I cloned a drive on the Mac Mini and when the clone started up everything looked in order. However, some apps were giving warnings or dumping when they started.

Twitter for Mac would ask for credentials and then fail.
MS Office 2011 kept giving a warning about the database.
Firefox was missing a profile.

Permissions seemed to be the culprit and then I ran across this forum thread. http://support.mozilla.org/my/questions/785562

The fix was as easy as:
Run this command in terminal from your home directory
sudo chown -R `id -un`:`id -gn` ~

Wireshark on Ubuntu 11.10 No Interfaces

2011.10.26

When installing Wireshark on Ubuntu I’ve run across the issue of no interfaces. Below are the steps to revolve that issue.

Install the setcap executable
$ sudo apt-get install libcap2-bin

Create wireshark group
$ sudo groupadd wireshark

Add your user name to group wireshark
$ sudo usermod -a -G wireshark YOUR_USER_NAME

Change the dumpcap directory to group wireshark
$ sudo chgrp wireshark /usr/bin/dumpcap

Change mode to 750
$ sudo chmod 750 /usr/bin/dumpcap

Grant capabilities with setcap
$ sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap

Verify the change
$ sudo getcap /usr/bin/dumpcap
