Molly-guard to save the day

If you have one or multiple boxes running somewhere at a remote location and you manage them trough ssh, you’re possibly familiar with the following situation.
It has been a long night.
On your desktop there are multiple terminals gaping in the dark.
During the whole night, some of these dark ships transported you to far remote playgrounds and back.
The other  ones were mere destined for local hocus-pocus.
But it’s time to call it a day and go to bed.
You fire away the ‘poweroff’ command just to realize a fraction of a second later that this was the window to your homebrew webserver…

But it’s too late.
The connection is lost and the machine has no wake on lan…
Now you have to get out of your chair, find those damned pants and go all the way up to the attic to switch it back on.

No one likes this horrible situation. So Molly-guard is here to save the day.
Molly-guard is is a bunch of scripts that capture the halt, reboot, shutdown and poweroff  commands and give you a second chance.
By checking if the tty has been created by sshd, it checks whether you’re logged on from a remote machine.
If that’s the case, molly asks you the hostname of the machine you want to shut down.
If the hostname you entered does not match the hostname where Molly is running on, you’re saved :)

You might think this is a silly tool, but after a long time of silence, I’m back to using my home server and just saw this screen:

A little cool thing to know:

A shield to prevent tripping of some Big Red Switch by clumsy or ignorant hands. Originally used of the plexiglass covers improvised for the BRS on an IBM 4341 after a programmer’s toddler daughter (named Molly) frobbed it twice in one day. Later generalized to covers over stop/reset switches on disk drives and networking equipment. In hardware catalogues, you’ll see the much less interesting description “guarded button”.

Pirate Party Ghent has a blog!

It’s here… The Pirate Party Ghent Blog!

If this is the first time you’ve read or heard about the ‘Pirate Party’, then you’ve missed out on some great international news.
So, time to get to the Wikiboats and loot yourself some knowledge!
The Pirate Party is a political party founded in Sweden by Rickard Falkvinge in 2006 and has been founded in at least 40 countries ever since.
The red line throughout their program’s are support for civil rightsdirect democracy and participation, reform of copyright and patent law, free sharing of knowledge (Open Content), data privacy, transparency, freedom of information, free education and universal healthcare.
Above that, it’s the only political party that has spread over country-borders.
Check out the Pirate Party International if you want to learn more about that.

But I started out with the cool news about the Pirate Party Ghent Crew’s Blog, so let’s get back to this specific part of the Pirate Party Belgium.
So yes, there is a Pirate Party in my country, even better, in my city :)
There is a weekly awesome meeting from the Pirate Party Ghent Crew.
I fully understand that now you know, you’re eager to know what’s happening there…
On the Pirate Party Ghent Wiki page, you’ll find the meetingnotes of all past meetings, aswell as the agenda for future meetings.

Are you living in Belgium, and want to find out if there is a Crew around, find out at the main Pirateparty Belgium Wiki, or start your own ;)

[FSF]: Stand up for your freedom to install free software

Stand up for your freedom to install free software — Free Software Foundation — working together for free software.

When done correctly, “Secure Boot” is designed to protect against malware by preventing computers from loading unauthorized binary programs when booting. In practice, this means that computers implementing it won’t boot unauthorized operating systems — including initially authorized systems that have been modified without being re-approved.

The biggest issue with the “Secure Boot” system, is that it’ll create a vendor-lockin. This has been seen with the android system as well, but it’ll be Microsft pulling the strings on this one.

Some other interesting reads on Secure Boot:

Time Wasters – Part1

We all know how easy it is to lose track of time while surfing the awesome internet.
During the last months, I’ve been bookmarking some of the most useless sites that I came across. (Without a reason at that time)
Now I have this folder full of time-wasting websites sitting in my toolbar and wondered whether to delete it or keep it…
So I came up with the brilliant idea of putting the list up here for later referral whilst sharing it with you :) That’s double karma!
Here we go.

Must see documentary on Privacy [Dutch]

Yesterday there was this documentary on the state of the internet, privacy and security (in Belgium).
The  idea was based on David Bond‘s movie/experiment “Erasing David“.

Dirk Leestmans (journalist) hired a private security audit and asked him to hack Freek Braeckman‘s computer and bank account within the next three days.

Dirk also goes deeper on the different used technologies applied by the Belgian Police force to track people.

Watch the video:
