Connect NAS to your Computer Directly

My Lenovo ThinkCentre Edge 72z comes with USB 2.0. Its maximum throughput is 480Mbit/s but the effective is about 35 MB/s or 280 Mbit/s. I want to improve file transfer speed between my computer with external hard disk by replacing USB 2.0 with Gigabit Ethernet which provides higher bandwidth.

If I connect my QNAP TS-112 which has a gigabit ethernet to TL-WR842ND which supports wireless 802.11n with maximum 300MBit/s and wired fast ethernet with maximum 100Mbit/s, the bottleneck will limit the transfer speed to 100Mbit/s. There are two solutions to improve: get a faster wireless router or connect TS-112 to ThinkCentre Edge 72z directly.

Because my ThinkCentre Edge 72z connect to TL-WR842ND via wireless 802.11n, I have an empty gigabit ethernet. Therefore, I choose to connect TS-112 with gigabit ethernet directly. TS-112 may access internet through the wireless connection on ThinkCentre Edge 72z when it is working.But nobody may see it, even we share the same wireless router. Continue reading

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.

Online Storage with File Sync Client in Linux

Copy.com is one of my heavy use online service. It provides Copy App for file sync and a generous 15GB storage. Best of all, when you share (and enable the sync) with others, you may share the cost of storage rather than everybody pay for full. You may see their video for Fair Storage on YouTube.

Before sign up for Copy.com, I use Dropbox because it is reliable and provides a file sync agent on Windows, Mac, and Linux. The only problem is the free storage is not enough to me, but the paid version is more than enough and too expansive.

I also try Ubuntu One, but it didn’t sync properly. For example, when I add some files from office PC, they won’t be synced back to my home computer sometimes.

Box.com, SkyDrive, and Google Drive are pretty good, but doesn’t officially provide a Linux client.

Turnkey with VirtualBox may save your time! Just download ZurmoCRM VM from TurnKey, launch in VirtualBox, change network ip setting, and you may use your browser on host system to test ZurmoCRM.
