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

tavshed — Wed, 20 Jun 2012 14:08:11 +0000

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` ~

Installed x11vnc:
apt-get install x11vnc

Create /etc/init/x11vnc.conf file:

script
x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log
end script

After restart, x11vnc shoud listen on vnc startard port – 5900.

Script is based on upstart event mechanism when Lightdm emits login-session-start event, x11vnc is started.

Wireshark on Ubuntu 11.10 No Interfaces

tavshed — Wed, 26 Oct 2011 18:50:28 +0000

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

iCamSource UDP Ports

tavshed — Wed, 14 Sep 2011 17:20:25 +0000

iCamSource requires UDP ports 12000-12100 be forwarded to the computer. UPnP handles well, but a change to pfSense and not using UPnP made me have to look for a solution.
