Xming with Raspberry Pi
This is detailed recipe (with bad puns!) for getting a Raspberry Pi displaying, out-of-the-box, via PuTTY and Xming on Windows. The method described is headless (AKA crustless: the Pi needs no keyboard, mouse or TV/monitor connected to perform it) but it's not compulsory to be so :). This is just a convenient method to make some simple file changes (that I use) with only a network cable and micro USB power connected to the Pi.
The method uses a Linux computer for setting the Raspbian image on the SD card (Raspbian changes shown here could just be deferred on a headed Pi). You need the Pi, not yet powered-up, connected to your network plus an SD card + USB adaptor; the latter just for interfacing the SD card to the Linux computer if it has no SD card slot.
Note: for this method the network (192.168.0.0) has connected: a Windows computer, raspberrypi (will be set to 192.168.0.6) and an internet gateway machine/firewall/router (192.168.0.5). A Linux computer is also needed, but it does not have to be on the 192.168.0.0 network.
Some of the window captures below may not exactly match what you now see with the latest Raspbian «wheezy» image.
Pi & bash
Download, copy to SD memory and customise the Raspbian «wheezy» image.
Note: commands shown (
$ command) in this section are for the Linux computer.
Download Raspbian «wheezy» 2013-09-25-wheezy-raspbian.zip to, for example, a Linux computer directory /scratch (the zip is 577 MB download and the extracted image, for the SD card, is 2.75 GB).
$ cd /scratch $ sha1sum 2013-09-25-wheezy-raspbian.zip 99e6b5e6b8cfbf66e34437a74022fcf9744ccb1d 2013-09-25-wheezy-raspbian.zip $ unzip 2013-09-25-wheezy-raspbian.zip Archive: 2013-09-25-wheezy-raspbian.zip inflating: 2013-09-25-wheezy-raspbian.img
Plug your SD/adaptor into the Linux computer (best to reformat the SD card first). Find the device that is your SD card
$ fdisk -l ... Device Boot Start End Blocks Id System /dev/sdc1 8192 7744511 3868160 b W95 FAT32
/dev/sdc1partition, for me, and a 4GB SD card (but check really carefully you get the right device + the SD card is about to be imaged and all its original contents lost!)
$ umount /dev/sdc1 umount: /dev/sdc1: not mounted
just in case it is mounted and copy the image to the SD card (takes a while)
$ dd bs=4M if=2013-09-25-wheezy-raspbian.img of=/dev/sdc 706+1 records in 706+1 records out 2962227200 bytes (3.0 GB) copied, 601.61 s, 4.9 MB/s
Note: use of device:
/dev/sdc, not the first partition on the device:
to flush system buffers before removing the SD/adaptor.
You can see the Raspbian partitions on the SD card
$ parted -l ... Model: SanDisk SDDR-113 (scsi) Disk /dev/sdc: 3965MB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 4194kB 62.9MB 58.7MB primary fat16 lba 2 62.9MB 2962MB 2899MB primary ext4
Note: you now have two partitions, the first
/bootand the second
/, for the Raspbian file system.
Unplug the SD/adaptor and plug it back in again. The new partition will not mount if you don't do this.
/dev/sdc2and go to the location of the first, of three, files to be changed
$ mkdir /media/external if the directory /media/external does not exist $ mount -t ext4 /dev/sdc2 /media/external $ cd /media/external/etc/network
I'm going to set the interface on the Pi to be static address: 192.168.0.6, and the internet gateway: 192.168.0.5. First edit file
interfaces(file changes are show in unified format:

Add at least one nameserver to file
/media/external/etc/resolv.conf(my gateway is also a DNS server). You can just add your ISP's DNS servers.
Change directory (i.e. up to
/media/external/etc) and edit file

Get out of the mounted partition and dismount it
$ cd $ umount /media/external
You are finished on the Linux computer. Remove the SD/adaptor.
Transfer the SD card to the Pi and power it up. It should boot and be able to respond to ping and service SSH requests.
$ ping 192.168.0.6
Ping should respond on the Pi itself and elsewhere on the network (and where named to:
If you have a problem, or get one later, you can move the SD card back to the Linux computer, mount partition 2 again and examine the logs in directory
I clean SD cards with the official SD Association formatter, before reusing them, as it removes any partitions automatically.
Use PuTTY to login to the Pi remotely via SSH, configure and update the Raspbian OS, and prepare for use with XDMCP and X-Forwarding.
Note: commands shown (
$ command) in this section are for your Pi via PuTTY on Windows.
PuTTY.exeon your Windows computer.
Enter the address of raspberrypi (192.168.0.6 in this case), set the remote character set to UTF-8 and click «Open».
Click «Yes» to the PuTTY Security Alert...we do trust this host!
At the PuTTY terminal prompt respond
You should now have a command line terminal for
You need to «Expand Filesystem» (if your SD card is bigger than 4GB), set «Console Text console, requiring login (default)» for «Enable Boot to Desktop/Scratch», check/set «Internationalisation Options» and «Select» «Advanced Options/Update». Note: that your ssh server should be left enabled, and the default locale is for the UK. Re-run
raspi-configagain anytime you want to change these options.
You should be on the internet (via your gateway) so do a full upgrade
$ sudo apt-get update $ sudo apt-get upgrade
Go make coffee...upgrade may take some time!
You don't want all that login spam again and a reboot is now needed
$ touch .hushlogin $ sudo shutdown -r now
Your PuTTY terminal will disconnect, so close it, wait a while and reconnect with PuTTY when the Pi has booted (use ping to check it's up).
Log back in to the PuTTY terminal for user
roota password and remember it (optional...it's your Pi...you can rebuild the image yourself if you destroy it...plus you don't want to keep typing sudo to do useful work!)
$ sudo passwd root

~/.bashrcfor both user

Finally: I recommend you don't use startlxde or lxsession via PuTTY as you can't Logout cleanly and the Pi's resources may be left in unknown states (e.g. processes and files not gracefully flushed, stopped or closed).
