Expect examples and tips

If you can connect to any machine using ssh, telnet, ftp, etc then you can automate the process with an expect script. This works even with local programs where you would have to interact with a script or program on the command line. When I first starting using Expect I wanted a short but detailed description on how Expect performed its magic. I had to read the Expect O'Reilly book to gather all of the information I needed, but that was not very short. I'm going to give my shortened version of how it works, and answer the questions I had at the time I was learning it. Installing and getting started Expect is written as a Tcl extension and can be installed on almost any Unix type distribution. After Expect is installed find where it was installed to by issuing the command "which expect". Expect - Expect - Home Page.

Debian - How do I backup my Raspberry Pi. If you want to preserve all of the data, you will probably have to create a disk image.

debian - How do I backup my Raspberry Pi

Furthermore, Windows cannot recognize typical Linux filesystems, so you probably won't even be able to see your files, when you plug in your SD card. Creating a disk image will preserve not only files but also the filesystem structure and when you decide to flash your new SD card, you will be able to just plug it in and it will work. On Linux, you can use the standard dd tool: dd if=/dev/sdx of=/path/to/image bs=1M Where /dev/sdx is your SD card. Raspberry Pi. Backing up the SD card - what's difference .bin vs. .img? Joe Schmoe wrote:1) Yes - "cp" and "dd" will create the exact same file.

Backing up the SD card - what's difference .bin vs. .img?

And, as I said, the syntax for "cp" is easier, so there' s really no need to use "dd" for this task (or any tasks related to the making or saving of images for the Pi). Note to nitpickers: I didn't say there's no reason to use "dd" ever - there are - but not in this simple case.2) No, you can't use "scp", because "scp" refuses to work with anything other than an ordinary file. You can't use device names with "scp". Why is it the simple method never works? Raspberry Pi Disk Images. RPi Debian Auto Login. RAID Pi – Raspberry Pi as a RAID file server. This mini-project uses a Raspberry Pi as a RAID array controller.

RAID Pi – Raspberry Pi as a RAID file server

Now it won’t be the fastest raid controller on the planet, but if you’re only doing a bit of streaming, and a bit of backup, and would like a bit of redundancy, then this solution might be for you. OK, maybe not. The performance will be slow. Very slow. How to Turn a Raspberry Pi into a Low-Power Network Storage Device. Mix together one Raspberry Pi and a sprinkle of cheap external hard drives and you have the recipe for an ultra-low-power and always-on network storage device.

How to Turn a Raspberry Pi into a Low-Power Network Storage Device

Read on as we show you how to set up your own Pi-based NAS. Why Do I Want to Do This? The benefit of having an always-on network storage device is that it’s extremely convenient to have your data (or backup destination) always accessible to the computers both inside and outside your network. The downside, in most instances, is that you’re consuming a fair amount of power for the convenience. Raspberry Pi Disk Images. New Raspberry Pi development vm version 0.2 « Executing Gummiworms.

I mentioned recently that I planned to keep using TrueCrypt in GNU/Linux since I had used it profitably in Windows, and that I also intended to keep using the container approach where you create a single file of a certain size and then mount it to get your virtual file system. I’m reevaluating my plan. I still like TrueCrypt and will likely keep using it, maybe by alternating DVD backups between it and my new intended: the EncFS Encrypted Filesystem.

(And of course GPG is always good for many crypto jobs, and will also be part of my security framework.) The drawback with my TrueCrypt method is having to create files of fixed sizes. You either have a lot of empty space tied up or you’re bursting at the seams and can’t expand a volume. After adding another 200GB drive to the slug the other day, I didn’t want to make more decisions about container sizes. Summary of my vague crypto knowledge Let me be clear that I’m no expert at this stuff. What to do? The EncFS Encrypted Filesystem 1. 2. 3.

Get started with Fetchmail, Procmail and Dovecot. Having already shown you how to run your own web server using Apache, we'll now turn our attention to the most important application of networking: email.

Get started with Fetchmail, Procmail and Dovecot

Running your own mail server may seem like overkill, but there are a number of good reasons for doing so. And if you consider yourself well-versed in the lore of sysadmin, this is definitely a topic you need to be comfortable with. Read on! There are several aspects to mail serving: receiving mail from outside, delivering it to local mailboxes, serving mail from the local mailboxes to clients, providing web access to those mails and receiving and forwarding outgoing mail from the clients. There are two ways of getting the mail on to your system; you can run a full-blown mail server such as Postfix and set up the MX records to point to your IP address, or you can pull it from an external mailbox using Fetchmail.

How2SetUp a Raspberry Pi Windows file server - Simon The Pi Man. Ok this instruction sheet will allow you to setup a Raspberry Pi computer to act as a (NAS)Network Addressed Storage server so it will be possible for you to access files from any/all your windows PC's in your house using the Raspberry Pi to share the files on a disk drive attached to one of the usb ports on the Raspberry Pi. 1.

This will provide anyone with a few pounds/$ to spare, to create new innovative systems, whether embedded systems, home systems, or possibly the ultimate in shared processing such as "Peer to Peer Processing (P2PP)". The Raspberry Pi computer is a machine based on an ARM chip so has extremely low power consumption and should run on batteries. The machine is just a basic motherboard with a number of i/o ports including a TV out, sound out, usb ports, rj45 network port (on model B), hdmi, micro usb power, gpio interface and an sd card interface.

The default processor is a BroadCom BCM2835 processor with either 128Mb onboard RAM (model A) or 256Mb (model B). Full tecchie details are available from the Raspberry Pi details page if you require this info. Dovecot. Please see this mail about some reasons why this page needs to be updated.
