Steps to Update IP Address on MaxCDN:

1. Login to MaxCDN account. Go to “Manage Zones”.
2. Go to “Pull Zone” which you like to update.
3. Then go to “Settings” tab.
4. You will see a section titled “Origin Information”.  That will contain IP address of your old server. Click the “Edit” button in that section. (see screenshot) 
5. Then enter new IP-address in “Origin IP” field and click the “Update” button.  (see screenshot) 

Why don’t MaxCDN update IP address manually?

Its common to perform some testing on a test server, and then use another server, a different one, for production site. So IP-address change is not something very uncommon.

MaxCDN uses IP address to serve content faster. But rather than automatically updating their cache, say daily, they keep it forever! While I like the manual option to “Update” IP address is settings area, which gives advance users some control, it would be better if MaxCDN combine this manual option with automated cache-update.

Smart Auto-Update: A smart solution would be to update IP-Address when “Origin Server” starts returning HTTP 404-error. When there will be too many 404-errors, it may mean the server has been moved. Of course, CDN misconfiguration or origin server-downtime can also result in 404-error but “Smart” programs supposed too handle such cases as well!

Interestingly 39% of these top blogs are using self-hosted WordPress while 9% are using WordPress hosted service. That means more blogs use WordPress hosted than any other popular platform.

Movable Type which was quite popular once as a blogging platform is losing steam fast. This might because the top 100 blogs might have changed and chances are newer blogs are more prone to use WordPress.

Tumblr over the past year has really grown a lot. I wrote about how it has a lot more pageviews than WordPress.com or Blogspot.com blogs. While WordPress.com actually dominates with more visitors than other blogging platforms, clearly showing it seems to be better from a search engine optimization perspective.

This blog too started on Blogger and later migrated to self-hosted WordPress. If you are blogging which platform are you using? Do drop in your comments.

Why did we move?

rtPanel has been growing rapidly (already crossed 5000+ downloads mark). The optimized mark-up of rtPanel framework, improves the site speed and SEO capability. DevilsWorkshop being a part of rtCamp, we decided to use it as a case study to show rtPanel’s capability.  It was a perfect example to consider, as it has a huge reader base, vast content, multiple authors and different functional elements.

We also used this opportunity to rebrand the website with even better looks and refreshing design. Read this to know more about re-design.

Devilsworkshop was earlier running over rtBase framework (internally used in rtCamp). It was later evolved over 2 years of experiential learning with more than 1000+ WordPress projects. The ultimate goal of bringing it to public, was later achieved with launch of rtPanel.

A Good Friday:

On a fine morning of a Friday (February 5, 2012), we just decided to switch Devils’ Workshop on rtPanel. The development was done on live site and within 3 working days it was implemented.

The results are beyond our expectations and it concluded that rtPanel framework can truly do wonders. The increase in traffic was due the optimized markup and default integration of Yoast SEO plugin. The increased traffic ultimately lead to increase in Google Adsense revenue by whooping 85%.

Reference Screenshots:

1. Page Load Time

2.  Visitors Traffic

*Bounce rate is increased, as during design phase, the navigation to archive posts was not given. Now its been corrected, and we hopefully will see the better bounce rate in next months stats.

3. Adsense Revenue

We have more than 600 demo sites on our test server and cleaning them using any WordPress plugin out there was simply out of the question! Can you imagine logging into each WordPress, installing plugin, then scanning/cleaning up WordPress… for 600+ WordPress sites?

Below is combination of Linux commands we used.  Assuming you have logged into a Linux Shell and already have BACKUP of all files (including infected files) lets move ahead!

Command to list all infected files:

grep -lr --include=*.php "eval(base64_decode" /path/to/webroot

This is not necessary but its better to check some files manually to confirm if they have malicious code we are looking for. Also we can use this command after running cleanup command to crosscheck if cleanup is really successful.

Command to remove malicious code:

If above command gives you correct output, execute following command to perform actual cleaning:

grep -lr --include=*.php "eval(base64_decode" /path/to/webroot | xargs sed -i.bak 's/<?php eval(base64_decode[^;]*;/<?php\n/g'

Executing above will remove eval(*) codes.  Above command will also generate a backup version of files it will modify. For example, if it removes code from index.php, you will find a new file index.php.bak in same directory with original content of index.php

Now after running above command, you still find some more infected files, then you need to adjust search and replace parameters in for “sed” part.    You may also use following command for a “liberal” cleaning at the risk of breaking something. (in case you really break something, like I did, you can jump to “Troubleshooting” section below!)

grep -lr --include=*.php "eval(base64_decode" /path/to/webroot | xargs sed -i.bak '/eval(base64_decode*/d'

Trying to avoid re-appearance of this code injection

Its really though to cover every possible way to protect yourself from such attach in this post.

If you remember, WordPress community faced this kind of issue because of WP-PhpMyAdmin plugin sometime back. In our case, we found some old WordPress demo sites were having that plugin installed.

To remove WP-PhpMyAdmin plugin form all WordPress sites on your server, execute following command:

find /path/to/webroot -name "wp-phpmyadmin" -type d | xargs rm -rf

Above is all we did to get rid of eval(base64_decode(*)) codes from all files on our test server. If this happens again on our server, I will update this post with added info.

Troubleshooting:

Just in case you end up in a mess, below are some useful commands.

Missing <?php tag in the beginning:

To add “<?php: tag in the beginning of index.php files, in case if you remove it accidentally use following command:

find /var/www/ -name "index.php" | grep "/htdocs/index.php" | xargs grep -L "<?php" | xargs sed -i "1s/^/<?php \n/"

Don’t worry. If you already have a “<?php ” tag in the beginning, it won’t be added again.

Extra Newlines at the top!

If you find after cleanup, extra newlines at the top of your code, then use following command to remove trailing newlines. Extra newlines creates problem for blog feeds.

find . -name '*.php' -exec sed -i -e :a -e '/^\n*$/{$d;N;ba' -e '}' '{}' \;

I hope you will find this stuff useful.

Developers are happy as they have got an opportunity for a little branding. Our creative heads from rtCamp too got down to design the banners. You can see them here (For Bloggertowp redirection plugin and rtSocial Plugin)

How to change the header image:

You can also customize your plugin custom headers, as it’s a pretty simple process. All you need is to follow the steps below:

(this tutorial was written while developing the header image for our BloggertoWordPress Redirection Plugin)

Step 1: Design  a 772×250 pixel jpeg or png image. (No animated GIFs)

Step 2: Adding it to plugin’s SVN Directory:

• Create a directory in your system: mkdir b2w-plugin
• Checkout the code from WordPress plugin Directory:

svn co http://plugins.svn.wordpress.org/blogger-to-wordpress-redirection/ b2w-plugin

• Move it inside the directory: cd b2w-plugin
• Create one more folder into it. : svn mkdir assets
• Move inside that folder. : cd assets
• Store the Image which you want to display for your plugin inside assets folder.
• Use this command: svn add *
• Now Commit the code from your system to WordPress plugin directory : svn ci -m “Added Banner”.
• It will ask you for the svn username and password. Give it the proper authentication and you are done with the new banner updates for your plugin.

So, lets start getting creative and write your plugin links in the comment area for other readers to see.
