Question: Can I install openssh on one of the official linux distributions?I plan to use this along w/ a USB HDD as  NAS (network attached storage) over SFTP.How about a WebDAV server on this little pc?
Document: I love me some Rasberry PI. Pick one up if you are adventurous or want some low power computing. I use mine as a NAS (network attached storage) server.
Working perfectly as home theater pc using raspbmc. Using a powered usb hub so I can connect usb wi-fi adapter, rf adapter, usb stick, & keyboard/mouse for setup and maintenance.Connected to lcd tv via hdmi cable. 1080p @ 120Hz is perfect. Audio over hdmi working. Streaming content over network from NAS device and website streaming - hulu, netflix, & assorted xbmc add-ons.I plan to purchase another for my home and plan to push these as gifts for friends.
I use the Pi as my home Linux utility device. I use it to run basic services such as DHCP, Syslog, etc. and run scripts for maintenance and management. I would not use it as a media device, but for a super low power, low maintenance, device it is fantastic. I bought another one that I use as a utility device for my work, using it as an SSH, SCP, TFTP server and use a USB to Serial cable to configure new network devices.
Me and my Pi have been gone through a lot over the past year. This little board is a ton of fun. I use it for a variety of network functions and its nice it can run off of one of my routers USB ports. I just tape it to the side of the router and connect a LAN and USB adapter and its good to go as an always on small server.I'd recommend buying some heat sinks ( you can find them on here) and a case.
I ordered this to use as a minecraft server. It turned out to be way too slow to use. I still have it on the network and I'm planning to use it for a NAS, but I'm not sure how it will perform.
I bought this little guy to use as a web server and NAS server, and it worked perfectly. Here are my thoughts:Pros:+ Very tiny and doesn't get hot or loud. Basically silent and the size of a credit card, very low profile. Put it in a little case and no one will even know it's running!+ Does what it's meant to do, well.
I knew the limits going in. I tried to run a minecraft server on it, but could never quite smooth out the lag. Decided to re-purpose it as a receiver for my Plex Media Server. Although it can be a bit slow, paying ~$40 vs building an HTPC made the occasional wait worth it. Plan to get a second one for the living room television.RasPlex software is very easy to setup and install as well.
Great little computer. I use this plugged into a usb WiFi and usb HDD and running a http file server (apache2) for streaming media files over my wifi network. It's definitely much slower than a modern computer, but for the low wattage power consumption, price and small size, what did you expect?The only problem I've had was with the power. You really need a high amp usb charger to run this if you use usb devices without a powered hub.
Awesome little gizmo! I set mine up to be a simple printer server, I like the flexibility it has to do future projects with it. I had a nice NAS on it going for awhile but then it broke down, not because of the hardware, but because my lack of linux skills.
This is an awesome little computer which works really well for me as a file and media server running raspbian. At 5 watts, plus power for the separate USB hard drive, it is quite economical. Estimated 20 watts.I plan on getting another,to play with the digital io. There is also the option to add HD cameras which would be pretty cool.
