How to add free shipping notice on product listing and product view in Magento

NOTE: This tutorial assumes you're using an extension that uses the "special_shipping_group" attribute... But you can also use this tutorial to output any attribute you'd like into the product view and product listing.

Ok... Say you're using the "special_shipping_group" attribute, to specify which products should receive free shipping.

You would, for example, add an attribute called: FREE SHIPPING

Make sure you also set this visible under product listing, and product view, or else it won't display.

Following, you will assign this attribute to all the products that are to use this "FREE SHIPPING" attribute.

Now...

How to install BFD (Brute Force Detection)

Source

What is BFD (Brute Force Detection)?
BFD is a modular shell script for parsing applicable logs and checking for authentication failures. There is not much complexity or detail to BFD yet and likewise it is very straight-forward in its installation, configuration and usage. The reason behind BFD is very simple; the fact there is little to no authentication and brute force auditing programs in the linux community that work in conjunction with a firewall or real-time facility to place bans. BFD is available at: http://www.rfxnetworks.com/bfd.php

This guide will show you how to install and configure BFD to protect your system from brute force hack attempts.

Requirements:
- You MUST have APF Firewall Installed before installing BFD - it works with APF and requires some APF files to operate.
- Root SSH access to your server

Magento Mega Menu: Responsive Custom Menu MOD

Magento Mega Menu : Responsive Custom Menu MOD

Here is a modded Responsive Custom Menu I just did, adding named menu classes and positioning the custom block element above the menu items.

Why?

Original menu didn't have any unique class identifiers for menu items--it was partially unique, but nothing you can actually use to style any individual menu item.  Also I thought it made sense to have the custom block ABOVE the menu listing. After all, any custom element you want to show is likely going to be more important than the regular menu listing.

If you're interested in this, then simply download the attached Navigation.php or copy/paste over the following app/code/commmunity/WP/CustomMenu/Block/Navigation.php:

XBMC Confluence Flat Skin (MOD) - Modern / Flat design

Alright... Kinda off topic.

XBMC is my favorite media center, and the default skin Confluence is pretty dated--i.e. the icons/interface haven't been updated in forever.

I did try other skins, but mouse support wasn't anywhere near as good as the default skin Confluence--I use a logitech touch mouse and no keyboard.

Anyhow...

Increase Limit of Drupal Views Exposed Group Filters sort order

My original post: Exposed filters group: increase weight sort count (#delta)

This still hasn't been fixed at the time of this writing. So here we go...

Sort breaks, and does unpredictable sorting, if you use more than 20 options. E.g. say you have have an exposed grouped filter with a price drop down of more than 20 options, sorting will not work after 20 items, it will always spit out a different order than what you specify.

The fix

Edit the following Views module file:

sites/all/modules/views/handlers/views_handler_filter.inc

Look for this:

Speed up and secure Apache SSL encryption.

By default apache loads a bunch of encryption protocols. Most of which either are insecure and/or slow.

The location of these settings are based on DirectAdmin's Apache 2.4.x, however, you should easily be able to locate them in your apache .conf files.

vi /etc/httpd/conf/extra/httpd-ssl.conf

Set Apache to only use the fastest and best encryption algorithms.

Now comment out the default SSL settings and add new ones as shown below:

DirectAdmin blacklisted and whitelisted IP

Recently my IP address was blacklisted by directadmin on my own server.  Here's a how-to that may save you time, in case you're unable to login to DirectAdmin.

Start DirectAdmin in debug mode

cd /usr/local/directadmin
killall -9 directadmin
./directadmin b2000

Now try to log into directadmin. You should see the reason why you are unable to. For me it was "Blocking blacklisted IP xxx.xx.xxx.xxx"

How to install a new drive in Linux larger than 2TB with proper alignment

Let's assume that we already have a primary physical drive in our system (HDD or SDD), and have added a second drive to our box, which we need to partition and mount automatically on boot.

Here's how to that:

Let's see what physical drives we have installed in our server:

ls /dev/sd*

Since this is our 2nd drive, you should see /dev/sdb.

Example:

How to permanently raise ulimit 'open files' and MySQL 'open_files_limit'

The default ulimit (maximum) open files limit is: 1024--Which is very low, especially for a web server environment hosting multiple heavy database driven sites.

This ulimit 'open files' setting is also used by MySQL. MySQL automatically sets its open_files_limit to whatever the system's ulimit is set to--at default will be 1024.

NOTE: MySQL can NOT set it's open_files_limit to anything higher than what is specified under ulimit 'open files'--you can set it lower, but not above the 'open files' limit.

Anyhow...

This is how we raise the ulimit

To check the limits:

How to create an additional domain and use it as a domain pointers in DirectAdmin

Domain Pointers are designed to be exact duplicates of the domain they're created under. As such, you cannot edit many aspects of them.

However, if you wish to have the website data remain the same as the main domain, but be able to control email accounts, you can do it by creating the pointer as another full domain name, and then use symbolic links to link the website data to that of the main domain.

1) If the Domain Pointer exists, delete it.

2) Create the Domain Pointer as a full domain:
- User Level -> Domain Setup -> Add Another Domain -> domain=domainpointer.com

3) Link the data directory that of the main domain, requires ssh:

How to fix Linux error "read-only file system"

Recently our /etc/fstab got screwed up preventing us from SSH-ing into the server after a reboot. So we were given KVM access to our server.

Once seting up Java to allow unsigned certificates--hint: under the Java Control Panel click the "Security" tab, and slide the "security level" to the bottom "Medium" . We were then greated with a message:

'give root password for maintenance or press ctrl+d to continue"

Come to find out CTRL-C and CTRL-V doesn't work, you have to type the pass by hand--this was very tedious since my root pass is extremely complex.

So once in I soon realized that the system was mounted as "read-only"; meaning that you couldn't make any changes to it; or in other words, completely useless at this state.

DirectAdmin how to set an external email server for Domain Pointers

If you ever created domain pointers in DirectAdmin, you may have wondered how to set the domain pointer NOT to process email locally.

For instance say you have PRIMARYDOMAIN.com as the main domain under your DirectAdmin account--and it is set NOT to process emails locally, but rather have an external email server handle that; Under MX Records you un-checked "Use this server to handle my emails. If not, change the MX record and uncheck this option". So now you decided to create a "domain pointer" under that same account for another domain SECONDARYDOMAIN.com ... You set the proper MX records for this domain pointer under DNS settings, pointing to the external mail server, and think you're all good to go...

How to install an Apple Thunderbolt Display on a NON-Apple Thunderbolt PC with brightness control support

So... A couple of years ago I purchased a Thunderbolt capable motherboard  (Gigabyte GA-z77X-UP5), and an Apple's 27-in Thunderbolt Display--rather than it's (now-discontinued) Apple LED Cinema display--to go along with my Apple iMac 2010 (as a dual-display setup) which I was primarily using as an LED monitor for my Windows 7/8 PC.  Boy was that a mistake... LOL . Thunderbolt support on non-Apple computers was TERRIBLE back then. Maybe it still is terrible still, but I got some good news after all this time. More after the break.

How to prevent accidentally doing "rm -rf /" | How to Install safe-rm

As a server administrator, I rely mostly on root or sudo access--allowing me absolute control of the server. However, "with great power, comes great responsibility!"

You can easily accidentally do this devastatingly bad command of wiping your entire system clean.

rm -rf /
# or
rm -rf /*

Which looks almost identical to the popular command

How to specify where root email goes

Your server sends out a lot of email to user root. For example, CSF (ConfigServer Security & Firewall) sends out most security notifications to root.

So, this is how we specify what email address root emails go to:

vi /etc/aliases

Scroll to the bottom,  and add or replace  existing:

root: YOUR@EMAIL.COM

Save and exit, then reload the aliases:
