HP Pro 1102w printer installation in Debian with CUPS

All necessary information are available here.

And the bits that I care about:

Download and Install

Click the link, or cut and paste the whole command line below to download the driver.

    $ wget -O foo2zjs.tar.gz http://foo2zjs.rkkda.com/foo2zjs.tar.gz

Now unpack it:

Unpack:
    $ tar zxf foo2zjs.tar.gz
    $ cd foo2zjs

Now compile and install it. The INSTALL file contains more detailed instructions; please read it now.

Compile:
    $ make

Install driver, foomatic XML files, and extra files:
    $ su			OR	$ sudo make install
    # make install

(Optional) If you use CUPS, restart the spooler:
    # make cups			OR	$ sudo make cups

Now create printer entries for your spooler.

Once the above is done simply go to https://Your_cups_server:631/ and add the printer:

cups_p_1102w

and if everything went OK the driver will be visible somewhere near the bottom of the list as listed above.

Quad Core UDOO – Debian – compiling kernel 4.0.8

U-Boot 2015 http://www.igorpecovnik.com/2015/02/20/udoo-quad-debian-sd-image/

Download the software:

wget http://mirror.igorpecovnik.com/kernel/4.0.8-udoo-next.tar

extract it and only install the u-boot package:

dpkg -i linux-u-boot-4.0.8-udoo_1.8_armhf.deb

 

Kernel based on https://github.com/patrykk/linux-udoo

Install prerequisites:

apt-get install lzop kernel-package u-boot-tools dblatex docbook-utils \
 kernel-common libsgmls-perl libsp1c2 libtinfo-dev sgmlspl sp texlive \
 texlive-bibtex-extra texlive-math-extra xmlto xsltproc libncurses5-dev

Getting the kernel:

cd /tmp
mkdir kernel4.0.8
cd kernel4.0.8
wget https://github.com/patrykk/linux-udoo/archive/4.0.8.zip
unzip 4.0.8.zip

now change directory to the kernel folder and configure it:

make menuconfig

compile it – in my case it took approx 2 hours:

make uImage LOADADDR=0x10008000  modules

install the modules:

make modules_install

copy the kernel to /boot folder

cp arch/arm/boot/uImage /boot/
 cp arch/arm/boot/zImage /boot/

compile the dtb file:

make imx6q-udoo.dtb

copy dtb file
cp arch/arm/boot/dts/imx6q-udoo.dtb /boot/dts/
copy firmware
cp firmware/imx/sdma/sdma-imx6q.bin /lib/firmware/sdma/
configure your uboot
nano /boot/boot.cmd
then copy and paste this
setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext4 rootwait console=ttymxc1,115200
ext2load mmc 0 0x18000000 /boot/dtb/imx6q-udoo.dtb
ext2load mmc 0 0x12000000 /boot/zImage
bootz 0x12000000 - 0x18000000

if you use graphical interface you will probably want to replace the first line with:

setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext4 rootwait console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 ahci_imx.hotplug=1 quiet

then convert it to uboot format
mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

Now cross fingers, connect console cable and restart the device

StartSSL – NGINX SSL

To ensure that your website is securely running it needs to have https enabled. This short tutorial will list steps necessary to secure NGINX server with a free Class 1 certificate from StartSSL.

Assumption:

1. You have a server running NGINX
2. You have already setup free account with StartSSL
3. You have validated your domain with StartSSL

Prep Work:

Download the StartSSL CA Certificate using wget:
wget https://www.startssl.com/certs/ca.pem

Download the StartSSL Intermediate CA Certificate using wget:
wget https://www.startssl.com/certs/sub.class1.server.ca.pem

Create a unified CA Certificate file:
cat sub.class1.server.ca.pem >> ca.pem

 

Private key and Website Certificate

Use the StartSSL™ Control Panel to create a private key and certificate and transfer them to your server.

My naming convention:
Private key: website.com.original.key
Certificate: website.com.crt

Then execute the following steps:

Decrypt the private key by using the password you entered when you created your key:
openssl rsa -in website.com.original.key -out website.com.key

Secure your key:
chmod 600 website.com.key

Create a single file containing your signed certificate and the StartSSL CA certificates for Nginx:

cat website.com.crt ca.pem > website.com.unified.crt

Configure your nginx server to use the new key and certificate (in the global settings or a server section):

ssl on;
ssl_certificate /etc/nginx/conf/website.com.unified.crt;
ssl_certificate_key /etc/nginx/conf/website.com.key;

Reload nginx config or restart the service.
And you’re done!

Debian Package Installation Notes

apt-get

You can run a simulation to see what would happen if you upgrade/install a package:

apt-get -s install

To see all possible upgrades, run a upgrade in verbose mode and (to be safe) with simulation, press n to cancel:

apt-get -V -s upgrade

apt-cache

The option policy can show the installed and the remote version (install candidate) of a package.

apt-cache policy

aptitude

The console GUI of aptitude can display upgradeable packages with new versions. Open the menu ‘Upgradable Packages’. Pressing v on a package will show more detailed version information.

Or on the command-line:

aptitude versions

Passing -V will show detailed information about versions, again to be safe with the simulation switch:

aptitude -V -s install

Substituting install with upgrade will show the versions from all upgradeable packages.

Another option, if you don’t know the full name of the package, is formatting aptitude’s search output:

aptitude search -F "%c %p %d %V"

%c = status (package installed or not)
%p = package’s name
%d = package’s description
%V = available package’s version

Another way using dpkg and grep:

dpkg -s | grep Version

0
