NFSv4 exports exist in a single pseudo filesystem, where the real directories are mounted with the –bind option. Here is some additional information regarding this fact.
Let’s say we want to export our users’ home directories in /home/users. First we create the export filesystem:
sudo mkdir /export
sudo mkdir /export/users
and mount the real users directory with:
You can display the contents of a .deb package with the program deb-gview. To install run:
sudo aptitude install deb-gview
To have a look at the contents of the package garmin-upload-tools_1.2.0_all.deb run:
deb-gview garmin-upload-tools_1.2.0_all.deb
set the variable SANE_DEBUG_DLL:
export SANE_DEBUG_DLL=255
then run sane (xsane, scanimage) and look at debug output.

You can install Firefox add ons on your own by using the built in add on manager. But you can also use the Ubuntu/Debian package system to install some extensions such as the great Adblock Plus and the Noscript extension:
sudo apt-get install mozilla-firefox-adblock mozilla-noscript
The installation of the port knocking daemon is quite simple:
sudo apt-get install knockd
To start the knockd daemon automatically: uncomment START_KNOCKD=1 in /etc/default/knockd.
Configuration:
Edit the config file /etc/knockd.conf:
[options]
logfile = /var/log/knockd.log
[openSSH]
sequence = 7000,8000,9000
seq_timeout = 5
command = /sbin/iptables -I INPUT -s %IP% -p tcp --dport 22 --syn -j ACCEPT
tcpflags = syn
[closeSSH]
sequence = 9000,8000,7000
seq_timeout = 5
command = /sbin/iptables -D INPUT -s %IP% -p tcp --dport 22 --syn -j ACCEPT
tcpflags = syn
to open the port run (on the client side):

1.As 1st rule (INPUT 1) allow all traffic on loopback adapter lo (so your programs on localhost can communicate if all other traffic is blocked later)
sudo iptables -I INPUT 1 -i lo -j ACCEPT
2.Allow incoming traffic on port 80:
sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
3.Block all other traffic:
sudo iptables -A INPUT -j DROP
sudo iptables -L
sudo sh -c "iptables-save > /etc/iptables.rules"
change /etc/network/interfaces to automatically load the rules before network adapters are set up:
Just run:
sudo apt-get install gnome-bluetooth
