Joomla 3.1.x: ini_set() has been disabled for security reasons (old)

When I open my web using Joomla version 3.1x, I found annoying messages "ini_set() has been disabled for security reasons". Unfortunately, this warning prevent me to login into Joomla administration.

There are 2 way to fix it. You can choose one of these way:

1. You can edit [your root Joomla]/configuration..php

and add

error_reporting(0);
@ini_set(‘display_errors’, 0);

between <?php and class JConfig

it's become like this

<?php
error_reporting(0);
@ini_set(‘display_errors’, 0);

class JConfig {

2. or you can edit file [your root Joomla]/libraries/joomla/session/session.php and add @ in every ini_set command.

For Example in line 120 (line number may deferent for each Joomla version) it becomes like this.

@ini_set('session.use_trans_sid', '0');

done.... :)

Installing Debian 7 x64 ethernet card & wifi in Lenovo B490

Last week, I got problem for enabling ethernet card & wifi in Lenovo B490 after installing Debian 7.1 x64. I need to install it offline for at least enabling ethernet card or wifi to make it online. After googling, i decided to enable ethernet card first to make it online (easier).

To install ethernet card in lenovo B490, it uses chipset realtek r8169 and it needs to install its firmware manualy from debian.org. follow these step to install it:

1. Download realtek r8169 firmware https://packages.debian.org/wheezy/all/firmware-realtek/download
2. Install it by run this command
   # dpkg -i firmware-realtek_0.36+wheezy.1_all.deb

After that, make it online, and add repository required to update your system. Wifi in lenovo B490 uses chipset bcm43142 that does not exist in debian repository. I follow this guide http://forums.debian.net/viewtopic.php?f=30&t=109498 to install its wifi. Here are steps to do:

1. Download the driver from https://mega.co.nz/#!qIUySZYJ!PgfNRVCcXO-enbDuhziUqVCriMcDhbU-houaQ97c0yM
   or the link was broken just search in google "download wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb" or from this server
2. Install it manualy bu run this command
   # dpkg -i download wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb
3. Install network-manager by run this command
   # apt-get install network-manager

Installing ODOO 8 in Debian

Odoo was formerly known as OpenERP until May 2014. It was rebranded because version 8 of the software included apps including website builder, e-commerce, point of sale and business intelligence. The software conforms to standard expectations of ERP systems, while providing additional modules beyond the coverage of traditional ERP systems.

These are steps to install ODOO/OpenERP version 8 (latest release) in Debian (in my case):

1. Add this into your /etc/apt/sources.list
   deb http://nightly.odoo.com/8.0/nightly/deb/ ./
   or
   deb http://nightly.odoo.com/master/nightly/deb/ ./
2. Install odoo key
   # wget https://nightly.odoo.com/odoo.key
   # apt-key add odoo.key
3. update by run this command
   sudo apt-get update
4. install ODOO 8 by run this command
   sudo apt-get install odoo

Shellshock Vulnerability on Bash Shell

This is how you test your bash shell whether its vulnerable or not for 'shellsock' bug.
Run this on your linux shell (you don't need super user account for this):
 $ env x='() { :;}; echo vulnerable' bash -c "echo this is a test" 
if the result like this:
   vulnerable
   this is a test
then, you need to upgrade your bash version.

Just run (as superuser or sudo)
 # apt-get update
 # apt-get upgrade

It will show bash upgrade like this:
 Get:1 http://security.debian.org/ wheezy/updates/main bash amd64 4.2+dfsg-0.1+deb7u3 [1,501 kB]

After I upgrade my bash, the result becames like this:
   this is a test

I use bash version : GNU bash, version 4.2.37(1)-release (x86_64-pc-linux-gnu)

Repairing GRUB UEFI Dual Boot Debian 7.1 x64 and Windows 8 x64

Accidentally I failed to install AMD Catalyst 13.6 beta on my Debian 7.1 x64, and I lost my GNOME. For short, I can't recover my GNOME and I reinstall my Debian 7.1 without EFI mood  (my mistake). The Installer can not detect EFI and the only option to install bootstrap loader is MBR.

I can not start both my Debian and Windows. From Bios, I start boot via EFI DVD to start Debian CD Installer. I choose Advanced Option to fix bootstrap location from MBR to EFI Partition (System Reserved), and follow these step:

1. Update your Debian and run
   # apt-get install grub-efi-amd64
   This command will remove grub package, and choose yes
2. Configure your GRUB using this command
   # modprobe dm-mod
   # grub-install
3. Apply your new grub into EFI Partition
   # update-grub
4. This procedure only fix boot into Debian. To create boot option to load Windows 8 boot manager you need UUID for EFI partition by running
   # blkid
   write down UUID for EFI Partition (it may be label as "System Reserved") with size about 100M-130M.
   for my case UUID is 4842-E4F1
5. edit file /etc/grub.d/40_custom and at the end of file add
        menuentry "Microsoft Windows 8" {
          insmod part_gpt
          insmod fat
          insmod search_fs_uuid
          insmod chain
          search --fs-uuid --no-floppy --set=root 4842-E4F1
          chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
        }
   the file becomes like this:
        #!/bin/sh
        exec tail -n +3 $0
        # This file provides an easy way to add custom menu entries.  Simply type the
        # menu entries you want to add after this comment.  Be careful not to change
        # the 'exec tail' line above.
        menuentry "Microsoft Windows 8" {
          insmod part_gpt
          insmod fat
          insmod search_fs_uuid
          insmod chain
          search --fs-uuid --no-floppy --set=root 4842-E4F1
          chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
        }
6. reinstall and reconfigure your grub by issuing :
   # grub-install
   # update-grub

Done, now I have GRUB to my Debian and option to load Windows 8 Boot Manager
