Reverse tunneling SSH ... manual extract

-L [bind_address:]port:host:hostport
Specifies that the given port on the local (client) host is to be
forwarded to the given host and port on the remote side. This
works by allocating a socket to listen to port on the local side,
optionally bound to the specified bind_address. Whenever a con‐
nection is made to this port, the connection is forwarded over
the secure channel, and a connection is made to host port
hostport from the remote machine. Port forwardings can also be
specified in the configuration file. IPv6 addresses can be spec‐
ified with an alternative syntax:
[bind_address/]port/host/hostport or by enclosing the address in
square brackets. Only the superuser can forward privileged
ports. By default, the local port is bound in accordance with
the GatewayPorts setting. However, an explicit bind_address may
be used to bind the connection to a specific address. The
bind_address of “localhost” indicates that the listening port be
bound for local use only, while an empty address or ‘*’ indicates
that the port should be available from all interfaces.

Sherlock Holmes on Knowledge

Sherlock Holmes closed his eyes and placed his elbows upon the arms of his chair, with his finger-tips together. “The ideal reasoner,” he remarked, “would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it. As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after. We have not yet grasped the results which the reason alone can attain to. Problems may be solved in the study which have baffled all those who have sought a solution by the aid of their senses. To carry the art, however, to its highest pitch, it is necessary that the reasoner should be able to utilise all the facts which have come to his knowledge; and this in itself implies, as you will readily see, a possession of all knowledge, which, even in these days of free education and encyclopaedias, is a somewhat rare accomplishment. It is not so impossible, however, that a man should possess all knowledge which is likely to be useful to him in his work, and this I have endeavoured in my case to do. If I remember rightly, you on one occasion, in the early days of our friendship, defined my limits in a very precise fashion.”
“Yes,” I answered, laughing. “It was a singular document. Philosophy, astronomy, and politics were marked at zero, I remember. Botany variable, geology profound as regards the mud-stains from any region within fifty miles of town, chemistry eccentric, anatomy unsystematic, sensational literature and crime records unique, violin-player, boxer, swordsman, lawyer, and self-poisoner by cocaine and tobacco. Those, I think, were the main points of my analysis.”
Holmes grinned at the last item. “Well,” he said, “I say now, as I said then, that a man should keep his little brain-attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it. Now, for such a case as the one which has been submitted to us to-night, we need certainly to muster all our resources. Kindly hand me down the letter K of the American Encyclopaedia which stands upon the shelf beside you. Thank you. Now let us consider the situation and see what may be deduced from it.

Computer Programming Stupidity

Him: "Well, Qbasic is my favorite."
Me: "Nobody over the age of eight uses QBasic for serious purposes."
Him: "But they made windows with QBasic."
"

Vodafone’s DNS settings

I'm having problems surfing the internet? How do I change the DNS settings?
I'm having problems surfing the internet? How do I change the DNS settings?
If you're having occasional browsing issues, you can specify 'domain name servers' on your computer to see if this fixes the problem.

Vodafone’s DNS settings are:
• Preferred/Primary DNS: 203.109.129.67
• Alternate/Secondary DNS: 203.109.129.68
How to change these settings if you're using broadband:
• Go to Control Panel > Network Connections and select your local network
• Click Properties, then select Internet Protocol (TCP/IP)
• Click Properties
• You will see 'Use the following DNS server addresses' and enter the desired DNS server(s) in the space(s) provided
• Click apply and then try browsing the internet again

Vodafone Broadband settings

What are the basic settings for my Vodafone broadband?


These settings are the same for all our Vodafone fixed line broadband products.

Login: username (your username for broadband is your Vodafone fixed line email address eg. username@vodafone.co.nz)
Password: your password (lower case)
PPP: PPP over ATM (RFC2364) VCMUX encapsulation
VPI - 0
VCI - 100
Every ADSL modem or router has a slightly different way of entering in these basic settings. Simply look at the instruction manual that was supplied with your ADSL modem or router for full details on how to enter these settings correctly.Some brands of router ask for the DNS settings. If required these are
Preferred DNS server: 203.109.129.67
Alternate DNS server: 203.109.129.68
If you're switching to Vodafone broadband from another provider, we've put together a handy guide of all the settings you need to change.

Producing a list of all installed packages in Ubuntu

http://ubuntuforums.org/showthread.php?t=261366

"HowTo: Create a list of installed packages
I found out how to do this recently and thought it might be helpful to some people. To output this information to a file in your home directory you would use,

Code:
dpkg --get-selections > installed-software
And if you wanted to use the list to reinstall this software on a fresh ubuntu setup,

Code:
dpkg --set-selections < installed-software
followed by

Code:
dselect
"

Smart! -- So I put the resulting installed_software file on my ftp space.

So:

exec -w 1 -c "init=/linuxrc root=1f01 rootfstype=jffs2 console=ttymxc0,115200 ro panic=1"

gives:
1 second timeout,
linux cmdline:
init=/linuxrc root=1f01 rootfstype=jffs2 console=ttymxc0,115200 ro panic=1

=> root fs is at FLASH address 0x1F01 ?

Erik Naggum's Contempt Page

For the last hour or so I've been enjoying (and posting) nuggets of quotations from Erik Naggum's Contempt Page... Happy Snacking! :)

How applicable are the techniques of sound programming?

The programmer should not ask how applicable the techniques of sound programming are, he should create a world in which they are applicable: it is his only way of delivering a high-quality design.

Edsger W. Dijkstra:
Answers to questions from students of Software Engineering (EWD 1305)

Mastering Complexity or Not

"The computer, by virtue of its fantastic speed, seems to be the first [technology] to provide us with an environment where highly hierarchical artefacts are both possible and necessary. This challenge, viz. the confrontation with the programming task, is so unique that this novel experience can teach us a lot about ourselves. It should deepen our understanding of the processes of design and creation, it should give us better control over the task of organizing our thoughts. If it did not do so, to my taste we should not deserve the computer at all!"

The humble programmer (Turing award lecture, EWD 340)

http://agilewebsolutions.com/products/1Password

If so, I think I forgot the question...

...along with my password (again ... :( )

The problem with using multiple machines and/or browsers, like I do, is that if you once forget one of your many (different, right? ;-) ) passwords for online services, you start to chase your tail trying to re-synchronize the remembered passwords in the browser cookies and/or other magic.

Scheme and Common LISP on JVM

Some interesting discoveries lately...

Kawa is Scheme on JVM (so is SISC) - a GNU official project.
Runs on Sun and various other JVM's.

Armed Bear Common LISP (ABCL) is CL on JVM

Clojure is new and a bit different -- and sounds very impressive indeed from the presentation(s) at http://clojure.blip.tv
Designed to interoperate easily with Java and other languages on the JVM platform.
The designer (Rich Hickey) has removed dependencies on concrete implementations... e.g. abstracting cons's to first and rest.
seq replaces lists as an abstraction.
It's closer to CL than Scheme (Rich says so).
Looks very promising.
