Keeping SSH Session Alive

Preventing a SSH connection from dropping while you are inactive or waiting for a script to finish is quite easy. If you are on a Ubuntu or Debian client you only have to add one line to

/etc/ssh/ssh_config
ServerAliveInterval 5

In OSX the config file for ssh can be found in /etc/ssh_config.

Actually this line sends a keep-alive packet to the server every 5 seconds. You can change the interval as you like, but for me it works best with 5 seconds.

Alternatively you can also use the parameter when connecting to the remote host. The command looks like this:

ssh -o ServerAliveInterval=10

Make backlight adjustment work in Ubuntu on the Panasonic CF-R7

I was struggeling with the backlight quite for a while now. But finally I found something which finally works.

First you need git core installed

sudo aptitude install git-core

Next you checkout the module

git clone git://git.myrix.net/pana_acpi

The next step is compiling and loading the module

cd ./pana_acpi
make
make install
modprobe panasonic_acpi

At this point you can already check if the brightness buttons are working.
Next copy ./pana_acpi/acpi/* to /etc/acpi
and restart the acpid daemon.

/etc/init.d/acpid restart

This module should work on all the 7-Series from Panasonic. I only tried it out with my CF-R7.

Flight Simulator X is a bit crazy

Today I was flying from Chubu Nagoya Airport to Kansai Intl. with an Airbus A-320. I was just approaching the destination airport, when an error came up.

It says that the computer run out of memory. The computer is running Vista 64 and has around 8GB of RAM.

This is really a weired behaviour :s
