Getting one of your Five-a-Day – connecting Remotely to a Raspberry Pi from Linux Mint

It’s Christmas. To mark the occasion, my son bought me a top-of-the-range computer…

Christmas has come early ! Er, hang, on…

Yes, a Raspberry Pi 2 b-spec, complete with 900 MHz Quad-core ARM processor and 1 GB RAM.

Getting it up and running was a bit more of a challenge than I had anticipated.
The Pi uses HDMI for Video output and my ageing monitor is not equipped for HDMI…

The best program on TV – NOOBS doing it’s thing.

In the end, I had to “borrow” the TV.
This arrangement was, of necessity, extremely temporary. The TV had to be back in it’s usual place ready for The Strictly-TOWIE-Dancing-Get-Me-Out-Of-Here Christmas Special, on pain of pain.
Therefore, my first Pi project was to connect to it remotely from another machine, namely, my Linux Mint Laptop.
This will enable me to run the Pi headless (i.e. without a monitor/keyboard/mouse attached to it).

I’m going to cover two different methods of connecting to the Pi.
The first is using ssh to connect to the command line.
The second is to connect remotely to the Raspbian desktop itself.

Just to avoid any confusion, I will be referring to the Raspberry Pi as “the Pi” and the machine I’m connecting from as “Mint”.

Tunneling X over SSH on Ubuntu 9.10

“Just a second”, you’re thinking, “I thought this blog was supposed to be about Oracle stuff ?”
This is true…broadly speaking. However, I’ve spent a fair chunk of the last week playing with Ubuntu 9.10 server working up to putting Oracle on it. This particular mini-adventure will come in handy when I come to do the actual install as Oracle uses a graphical interface as it’s main installation tool.

So, this tuneling X over SSH sounds pretty impressive. Tuneling itself sounds very technical, a fact augmented by the inclusion of a TLA in the phrase. And the X just serves to make it sound rather mysterious and exciting.

As is so often the case in such matters, the truth is rather more prosaic. Continue reading

Installing Ubuntu Server and SSH setup

It is said that the Devil makes work for idle hands. I’ve got a week off. I know, I’ll have a crack at setting up an Ubuntu server on a desktop PC.
Note to self – I really must get a life. Apparently they can be quite useful.

Right now, however, it’s probably a good idea to set out what I’m trying to achieve here.

This server is just something for me to play around with at home. I don’t need to worry too much about large amounts of traffic.
I want to keep my holiday snaps and my music on it so I can access them from the other machines in my house.

I also want to install Oracle 11g on it at some point, so I have somewhere to play with an up-to-date version of Oracle.
As 11g tends to get a bit sniffy if it’s got a GB or less of physical memory to play with, I need to make sure that the host machine has enough memory to accommodate it.

I’ll post about the Samba setup and Oracle installation separately. For now, I want to concentrate on the initial Server installation and SSH setup. Continue reading
