Using rsync to syncronize files between two systems

Rsync is a very handy tool at synchronizing the contents of two folders/directories.

And while being great for local folders, it also works remotely, via SSH, thanks to the -e ssh parameter: # rsync -ave ssh sourceserver:/home/user/ /home/user will sync /home/user from the sourceserver with /home/user on the local machine.

Raspberry PI as NAS

A friend of mine was wondering about using a Raspberry PI as a NAS, the question being: how fast is the PI at file transfers from/to an external hard disk connected via a USB rack.

So I booted up my PI, mounted some random 3.5 inch Samsung 160GB SATA hard drive inside another random Spire USB-SATA external (powered) rack and gave it a go at some testing.

Upgrading the SD card used on WRT54GL v1.1 running dd-wrt

If you’ve done the SD card mod on WRT54GL, you might at some point change it with a bigger / faster card. You could just replace the SD card with a bigger one, but then you’d have to install/re-configure everything set up on it (like Optware stuff). […]

View sorted list of connected IPs

At points one may need to quickly check and see who is connected to a server – and in case of servers running services such as http, ftp (so on) the number of their connections.
The netstat program does indeed display the list of connections, but browsing through it when there is a large number of connections is rather difficult.

RaspberryPI – first impression

I couldn’t resist not trying out my RaspberryPI which I received yesterday 🙂

I quickly recycled one of my SD cards, installed the recommended SD image and booted it up.

After the initial boot setup screen (and partition resize), you can see it running connected to a monitor via HDMI, with a keyboard, mouse and wireless adapter (Asus WL-167g) all plugged in a 4-port USB hub…

My RaspberryPI has arrived

Yay! After around 4 months of waiting, it is finally here. My very own Raspberry PI 🙂

It appears I received a rev2 board which, among other small improvements, should feature 512MB of RAM instead of 256.

The board comes packed in a nice neat pink(?!) case, together with a quick start guide giving you the essential information on how to get the thing started…
