Hi all,

After some time finally I will write a new post here.

Today a will write how to maintenance debian/changelog file in a source package.

= Configuring environment variables =

First you need export some environment variables.

EDITOR="vim"

DEBFULLNAME=”Ragner Magalhaes”

DEBEMAIL=”foo@ragner.org”

export DEBEMAIL DEBFULLNAME EDITOR

You can put these lines above in your .bashrc file

= To create a new debian/changelog file =

In the project’s directory just run

$ dch --create

To create a new debian/changelog file.

= To increment the Debian release number =

To increment the package release number run the follow command

$ dch -i -U -D "unstable"

So it will open the debian/changelog file to you  write some comments.

Thanks to Anderson Lizardo[http://lizardo.wordpress.com/] and Alvinho.

Hi all,
today I will teach how to set the screen size using xrandr Linux command.

To find out what sizes are available, run:
$ xrandr -q
SZ: Pixels Physical Refresh
*0 1024 x 768 ( 271mm x 203mm ) *75 70 60
1 800 x 600 ( 271mm x 203mm ) 75 72 60 56

To set the screen size to an available size, run:
$ xrandr -s 800×600

Thanks,
God bless you … [:P]

The following example uses eth1 for the wifi interface though this may be wlan0, ath0 or something else in your case.

Preparation

Ensure that network manager has been stopped and then bring the interface down.

sudo /etc/dbus-1/event.d/25NetworkManager stopsudo ifdown eth1

Configuration

1. Switch the card into ad hoc mode

• sudo iwconfig eth1 mode ad-hoc

1. Set the channel/frequency that you want to use.

• sudo iwconfig eth1 channel 11

1. Add the name (ssid) for the network you want to create/join. Use single quotes if there is a space in the name.

• sudo iwconfig eth1 essid 'name'

1. Add a WEP encryption key

• sudo iwconfig eth1 key 1234567890

Activation

1. Bring the interface back up

• sudo ifconfig eth1 up

1. Start dhclient to get an address

• sudo dhclient eth1

1. If you want to do it manually, you will have to make up an IP address.

• sudo ifconfig eth1 10.0.0.1 netmask 255.255.255.0

echo 1 > /proc/sys/net/ipv4/ip_forward

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

Package dependences:

# apt-get install debian-keyring debian-archive-keyring

If you get o follow error from an unofficial repository:

W: GPG error: ftp://ftp.ragner.net etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 08GC463D1F41D098

Take the GPG key

# gpg --keyserver subkeys.pgp.net --recv-keys 08GC463D1F41D098

and add to apt

# gpg --export --armor 08GC463D1F41D098 | sudo apt-key add -

End

If you run /etc/init.d/apache2 start but the apache2 do not start.
A solution can to be
edit /etc/default/apache2 and change NO_START to be 0

Configure your xserver, here is the xorg:
# dpkg-reconfigure xserver-xorg

My keyboard layout “us” and own variant “us_intl”
$ cat /etc/X11/xorg.conf
…
Section “InputDevice”
Identifier “Generic Keyboard”
Driver “kbd”
Option “CoreKeyboard”
Option “XkbRules” “xorg”
Option “XkbModel” “pc104″
Option “XkbLayout” “us”
Option “XkbVariant” “us_intl”
EndSection
…

Now configure your locales and select the default:
# dpkg-reconfigure locales

Reboot your system:
# init 6

First, put n pages at each leaf with mpage comman:

$ mpage -n a.ps > b.ps

* n can to be 2, 4 or 8

To reverse the pages:
$ pstops "2:0@1.0(-0.00cm,0.0cm),1U@1.0(21cm,29.7cm)" b.ps > c.ps

# aptitude install postfix sasl2-bin

Edit /etc/postfix/main.cf
—
#
# Transport com relay autenticado
#

smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/saslpass

—
Edit /etc/postfix/saslpass

smtp.servername userlogin:password

Then, run:

# postmap /etc/postfix/saslpass
# postfix reload
