You need a recent virtualbox, or the (proprietary) server version of it (which is free as in beer). In any case, the steps below work for me on Ubuntu intrepid: |

You need a recent virtualbox, or the (proprietary) server version of it (which is free as in beer). In any case, the steps below work for me on Ubuntu intrepid:
/etc/apt/sources.list:
deb http://download.virtualbox.org/virtualbox/debian intrepid non-free
Execute:
$ wajig install virtualbox-2.1
Answer yes to install the kernel module, it should just work. Create the virtual image:
$ VBoxManage createvm -name ubuntu -register $ VBoxManage modifyvm ubuntu -memory "2048MB" -acpi on -boot1 dvd -nic1 nat $ VBoxManage createvdi -filename ~/.VirtualBox/Machines/ubuntu/ubuntu.vdi -size 20000 -register $ VBoxManage modifyvm ubuntu -hdb ~/.VirtualBox/Machines/ubuntu/ubuntu.vdi $ VBoxManage registerimage dvd ~/ext/debian-40r6-i386-netinst.iso $ VBoxManage modifyvm ubuntu -dvd ~/ext/debian-40r6-i386-netinst.iso
Start the image
$ VBoxHeadless -startvm ubuntu VirtualBox Headless Interface 2.1.2 (C) 2008-2009 Sun Microsystems, Inc. All rights reserved. Listening on port 3389
Connect to the image (requires X) on the same machine:
rdesktop localhost
Or you can login remotely by forwarding the 3389 port:
$ ssh -L 3389:localhost:3389 server
And from your desktop computer
$ rdesktop localhost
Install the system. After installing it, remove the cd (iso image) by
$ VBoxManage modifyvm ubuntu -dvd none
Stop the image (do not save changes)
$ VBoxManage controlvm ubuntu poweroff
Stop the image (save changes)
$ VBoxManage controlvm ubuntu savestate
Networking
In order to be able to login using ssh, do:
$ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/Protocol" TCP $ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/GuestPort" 22 $ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guestssh/HostPort" 2222
Then you can login on the server using:
$ ssh -p 2222 localhost
Or if you put this into your .ssh/config:
Host pythonnb HostName localhost User ondrej Compression no Port 2222
Then you can connect just by ssh pythonnb.
To forward the port 8000 for the Sage notebook, use:
$ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guest8000/Protocol" TCP $ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guest8000/GuestPort" 8000 $ VBoxManage setextradata ubuntu "VBoxInternal/Devices/pcnet/0/LUN#0/Config/guest8000/HostPort" 8000
Sage
Download and install Sage as usual in the virtual machine. Start the notebook:
$ ./sage ---------------------------------------------------------------------- | Sage Version 3.2.3, Release Date: 2009-01-05 | | Type notebook() for the GUI, and license() for information. | ---------------------------------------------------------------------- sage: notebook(address="") [...] ************************************************** * * * Open your web browser to http://localhost:8000 * * * **************************************************
And connect to http://localhost:8000 on your host machine.
Securing the Sage notebook
Do all of the below as the user ondrej, that will run the notebook server. Create an nbuser user that will run the actual worksheets:
$ sudo adduser nbuser $ sudo addgroup sageusers $ sudo adduser ondrej sageusers $ sudo adduser nbuser sageusers
Setup ssh keys, so that you can do ssh nbuser@localhost without a password. Create a working directory:
$ mkdir nbfiles $ chmod g+w nbfiles
You have to make Sage available just by calling sage and it needs to be in default paths, e.g. it's not enough to add the path to Sage to your .bashrc. Do it by:
$ cd /usr/local/bin $ sudo ln -s /home/ondrej/ext/sage-3.2.3-Debian4.0-32bit-Intel-i686-Linux/sage .
Create notebook.py:
from sage.all import * notebook(directory='/home/ondrej/nbfiles', port=8000, accounts=True, address='', ulimit='-u 100 -v 300000 -t 3600', open_viewer=False, timeout=120, secure=False, server_pool=['nbuser@localhost'])
And start it using:
$ sage -python notebook.py
Setting up lighttpd
$ wajig install lighttpd
Create /etc/lighttpd/conf-available/20-notebook.conf:
server.modules += ( "mod_proxy" ) $SERVER["socket"] == ":8080" { proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => 8000 ) ) ) }
Enable it:
$ sudo lighty-enable-mod notebook $ sudo /etc/init.d/lighttpd force-reload
And login to your computer from the outside world to the port 8080 (you can of course just setup the port 80 instead of 8080).
