DD-WRT for my TP-Link TL-WR842ND

My TP-Link TL-WR842ND freeze once or twice a day. It’s not the WAN because I may go online with other ports on FDDI modem. I cannot even login to my TL-WR842ND. Upgrade to the latest firmware doesn’t help, either. After 7 months, I give up and get a new AP.

Until last week, when I try to do more research to see if there is any solution, a YouTube names “TP-link TL-WR740N freezing, no connection until restart” catch my eye. It’s exactly what happen to me. And there are comments TL-WR842ND has the same problem, too. Aidin shadnezhad solve his problem by flash it with DD-WRT firmware.

Here comes the solution!

Assign a different Directory in ownCloud to Store All Backup Files

In Use TurnKey to Simplify ownCloud Installation, you may host your TurnKey ownCloud. In Access Shared Folder on VirtualBox from Guest Linux VM, you may use a shared folder on host from guest VM.

How about host TurnKey ownCloud and ask it to save all backup files in a shared folder on host to save efforts increasing the Virtual Machine Disk? Even on a different internal hard drive or external RAID for better protection?

You need to manually change the ownCloud configuration file and add www-data to vboxsf group in Linux.

Access Shared Folder on VirtualBox from Guest Linux VM

With graphical desktop, it is easy to move files between guest VM and host. But TurnKey is in text mode, I need a shared folder for file exchange.

Fortunately, it is easy to add a shared folder in VirtualBox. It may be auto-mount in guest VM.

Use TurnKey to Simplify ownCloud Installation

TurnKey is an convenient way to test new software without changing your work environment. No need to worried about the extra package or configuration might make your system becomes unstable. I like it very much!

I was looking for a Droprbox-like solution for backup small or frequently changed files. It must keep versions, auto-sync, and fast. Iomega Quick Sync is my favorite in 2001 but it’s not available in Linux and haven’t update for a long time. [Cloud] OwnCloud, a self-owned DropBox-Like Server(Chinese Version) catch my eye. Because ownCloud is available on TurnKey, I download and test it in VirtualBox. I also install the ownCloud desktop sync client in OpenSuSE 12.3 and it works great on Linux.

I am going to show you how to test TurnKey ownCloud in VirtualBox and share how I may use it in production.

Add more Input Method in OpenSuSE 13.1

I need to use Traditional Chinese in OpenSuSE. To be able to input Traditional Chinese correctly, I need extra input method which support Traditional Chinese. It is same to Japanese, Thai, and etc.

Copy.com’s Official CopyAgent in OpenSuSE 13.1

Download and Verify OpenSuSE 13.1 Image with Hash

OpenSuSE 13.1 is available for download on 2013/11/19.  To make sure it’s the same as the original, I use SHA-256² and MD5³ to confirm.

Partition Error and Fail to Install GRUB on Windows 8 Hard Disk

I have install Windows 8 Professional on my hard disk. It works fine until it is moved to another computer for Linux.

At first, I use Clonezilla to do drive-to-drive copy. It fails to copy grub to destination disk. Even I use GPartrd to delete all existing partition, it’s the same.

After a fresh install of Windows XP on my VirtualBox, I notice some program keep on using CPU while I am installing other programs. Windows Task Manager identify it is svhost.exe who  use 99% of CPU time.

Capture Salesforce Outbound Message with a PHP SOAP Listener

To integrate Salesforce and other system, you need to make sure they may communicate with each other.

Web-to-lead is an example for Salesforce to capture message from others. Another example is a variant of “Get data through Salesforce REST API” section in my last post. You may change the Salesforce Object Query Language (SOQL) in Apex code into Salesforce Object Search Language (SOSL) for more flexible database operation in Salesforce.

Another case is when Salesforce need to pass data to other service. This is our focus. Here I am going to how to capture Salesforce Outbound Message with PHP.
