Remote PGP and ssh ?

10 July, 2009 (16:00) | Uncategorized, security, technical | By: Joffie

With the Dutch government enforcing new laws on storing communication information there is a broader need for people to start using PGP to encrypt their e-mails.
I must admit that I haven’t been using it for a long while now. The main reason is that I often e-mail from a server that I ssh into from my laptop. I am not the administrator of that machine. That is the main reason that I don’t want to store my private keys localy on that server. I want them only on my laptop (or better, on an encrypted USB disk in my laptop).
But how to sign and encrypt mails if you haven’t got the keys on the server? What I want is something like the ssh-agent forwarding.

Style change

NuDonker

I must admit, I read a the website http://nu.nl/ a lot to check up on the latest (Dutch) news.
Of course I use Addblock Plus to get the site readable in the first place. But that is not enough for me. I think the site is looking way too bright. If google can save 750 Megawatt hours a year, I am sure a darker nu.nl can save some watt’s too.
To get google dark, you can use http://blackle.com/.

So I decided to write up a greasemonkey script to darken things up: http://joffie.swal.org/gm/nudonker.user.js. This uses an extra stylesheet to modify the existing styles.
Though It does give the desired effect, in some reloads you can still see that the rendering of the greasemonkey part takes up a little time. I guess I need to look in http://userstyles.org/stylish/ to get that effect fixed.

bullshit generator

Yesterday I got a mail from a friend with http://www.jurgensland.nl/download/adviesmatrix.pdf attached. The trick is to randomly pick a part of the sentence from each column. Put all those columns together and you’ve got a complete sentence of Dutch bullshit.

I hate to do random things myself when I’ve got a computer that can do random stuff for me. So here it is: http://joffie.swal.org/bs/. And to view the source: http://joffie.swal.org/bs/index.cgi?view-source.

uShare and the hidden telnet functions

30 March, 2009 (08:46) | technical | By: Joffie

Ever since I’d bought a xbox 360 I would like it to be able to play music and video as well as games. Because of lack of time I never had a lot of time to play around with it. Until today. On my server I installed uShare. This program is part of GeeXboX and shares data to a xbox 360 in your network.
Interested in all of the features I noticed a telnet interface. I am alway curious what one can do with the telnet interface especially when it is enabled by default.
De default port that is used is port 1337 (from the manual page).

GeekTool

geektool usageSome time ago, my employer forced a MacBook Pro on me (oh, the horror of my job) and I’m getting used to MacOSX more and more. Last night, I came across GeekTool, a tool to display text (or images) on your desktop. Following the examples, I’ve decided to add a somewhat stylish date / time thingy on my desktop (see image).

GeekTool can show files (tail), output of a shell command or images. It’s easy to setup and configure and simply handy! Highly recommended.
