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.

There are several ways to get the UUID.

The first one uses the /dev/ directory. While you are on is you might want to check other by-* directories,

$ ls -l /dev/disk/by-uuid

lrwxrwxrwx 1 root root 10 11. Okt 18:02 53cdad3b-4b01-4a6c-a099-be1cdf1acf6d -> ../../sda2

Another way to get the uuid by usage of the tool blkid as super user:

# blkid /dev/sda1

/dev/sda1: LABEL=“/” UUID=“ee7cf0a0-1922-401b-a1ae-6ec9261484c0″ SEC_TYPE=“ext2″ TYPE=“ext3″

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

Thanks,
God bless you … [:P]

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

# 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

My keyboard layout “us” and own variant “us_intl”
$ cat /etc/X11/xorg.conf

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

Reboot your system:
# init 6

$ 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
