Here's a bit more about what was in the article that I'm trying to
find... 


Meryl,
I've just read the article.

I find little in it to take issue with, except his apparent presumption 
that cracking is a subset of hacking, rather than cracking intersects 
with hacking.


The author apparently believes that all cracking techniques, such as 
dictionary or brute force attacks for example, are hacks. I doubt any 
serious hacker would agree. There is little hack value in an obvious 
approach, the author acknowledges as much himself .. hacking is 
predicated on novelty or creativity.


To state it another way, he believes all cracks are hacks, but not all 
hacks are cracks. He is therefore unable to properly differentiate 
cracking from hacking and has conflated them.


If I were challenging him I think this would be the basis of my challenge.

It's remained unchanged.

With stock hardware I get about 4.5 hours of solid use from a charge. I

No brainer, it came with an Ubuntu derivative pre-installed, but I

Marghanita,

I realise you posted this message quite a while ago now, but I've 
recently purchased four of the Agora Pro Netbooks and if you're still 
considering purchase I thought you might be interested in my comments. 
In summary I'm really very happy with them.


They're surprisingly solidly built for a machine of their class. They 
feel well-built with no flimsiness and I suspect you'd have to try 
pretty hard to do any real physical damage to them.


The operating system has been well localised for Australia and is Ubuntu 
8.04 based. The 8.04 is a little out of date, but the update process is 
obvious and works as expected. It was almost disappointing to discover 
that I didn't need/want to do much after creating my login account to 
customise it; the setup is quite sensible. All I ended up doing was 
disabling the Google gadgets on the desktop because they're not to my 
taste and installing a few application package that I like to use.


I find the keyboard quite comfortable to use, with the possible 
exception of the '/' key being a little awkward to get to from some 
angles. The touchpad works well, but again, from some angles I find that 
my thumbs sometime accidentally stray onto it while I'm typing. I'm sure 
both of these problems will dissipate with time as I become more 
familiar with it.


Wireless/sound work as expected. Bluetooth, as you will know, manifests 
as a small USB dongle which I haven't yet tried, but suspect will work 
just fine.


The screen is quite pretty, with default fonts small but readable even 
for someone rapidly turning middle-aged and both short and far-sighted :)


Happy to field any particular questions you (or others) might have.

Without knowing any detail I can tell you that this sort of problem
usually relates to you configuring a 'default route' on your ethernet
interface that overrides the default route that is normally pointing to
the Internet via your PPP interface. You don't need, or want, a default
route on your ethernet interface, so if you've got one, remove it. The
default route might appear as a configuration item for a 'gateway'. The
only default route you want is the one that pppd will provide with its
'defaultroute' option.

If you look at the routing table on the this machine, you should see
something like:

guglielmo# route -n
Kernel IP routing table
Destination   Gateway  Genmask Flags Metric RefUse Iface
220.233.1.45  0.0.0.0  255.255.255.255 UH0  00 ppp0
10.200.253.0  0.0.0.0  255.255.255.0   U 0  00 eth0
0.0.0.0   0.0.0.0  0.0.0.0 U 0  00 ppp0

The last line, the route to '0.0.0.0' is the default route I'm talking
about. You only want one of those. If you see another one configured
when your ethernet interface is up, that'll be part of your problem.


Your laptop machine should be configured something like this:

gateway 195.168.0.1

and your 'accounts' machine should look similar, albeit with it's own IP
address instead.


If you want your laptop and windows machines to be able to share your
Internet connection, then you'll need to configure what is sometimes
called Network Address Translation, or IP-Masquerade on your 'this' machine.

On my own machine here I use these commands:

/sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
/sbin/iptables -I FORWARD 1 -p tcp --tcp-flags SYN,RST SYN -m tcpmss
--mss 1400:1536 -j TCPMSS --clamp-mss-to-pmtu

But it is possible that Mandrake includes some way of automating this,
or even of configuring this transparently for you.

 I see two main challenges to solving this conundrum:
 
 * getting people to attend a meeting in the first place
 * encouraging people to continue to participate afterwards

Sridhar,
I'd love to be an active member of SLUG. The group seems pretty healthy and
by all accounts it reminds me of the best features of many of the computer
usergroups I remember fondly from the 80's.

I share(literally) Mary's child/meeting night problem. I have a schedule
that makes it just about impossible to attend meetings unless they're on a
Monday or Tuesday night. It's a very haphazard scheduling outside of that.
I'm not suggesting you change the night of the meeting, but I wonder if for
many people it's just logistic issues that prevent them from attending?

Many of the most succesful user-groups and clubs that I have seen operating
have achieved a great number of things, but they nearly always did it on the
back of a very strong social network. Usergroups are great as places to make
true friends and meet with them regularly for some face-to-face and focussed
time talking about common interests.

If you want to attract and retain members I'd maintain a focus on community
and sociality. It's something that every member will need to practice too
though; it isn't something that only a few can do. In the end that'll mean
that attracting and maintaining members will probably have to be a shared
concern. If it's only the committee worried about it you're probably in for
a tough time doing much about it.

Terry

 I think the use of offical greeters to assist new people get an orientation

If you get the right people doing this it could make a big difference I'm sure.

 I guess another option is to give the new members a nametag or something
 and then encourage an etiquette of existing members introducing themselves
 visitors during coffee time.

heh, if you're going to do nametags then everyone should be encouraged to
wear nametags, not just the newbies. Otherwise the name-tags alone can make
you feel uncomfortable and 'marked'.

Everyone wearing name-tags, while perhaps seeming a bit daggy, could
actually be a cool thing. You could, for example, have a scheme where other
people could endorse a persons nametag for exceptional behaviour. You know,
Gold Stars for being helpful or something. Maybe you could endorse your
nametag with things that you're prepared to talk about, help with or that
you are knowledgable about. This might provide a means of readily
identifying who the helpful people are, and perhaps encouraging people to
put in the little bit of extra effort to help people.

 One thing I love about SLUG is its excellent blend of technical and social

 at the same time there are plenty of avenues for meeting people and

I'm quite sure you're right, I wasn't trying to suggest that SLUG is
lacking, rather I was suggesting maintaining a strong focus on the social
element to underpin the other activities.

 There is also DebSIG, which I hear is even more informal. Unfortunately, I've 
 never been to make it to one since I don't like to go out drinking in the 
 middle of the week.

I've been to one DebSIG which I really enjoyed. I'd love to be able to
attend regularly, but unfortunately Wednesday nights are also nights I'm
unable to make.

Re: [SLUG] Who looks after your stack?

 I propose that in most cases, it's been the UNIX admins who put together the
 systems then install and basically configure the apps that make up the
 suite of apps that can be called an Information System such as a httpd,
 php/perl plus SSL/TLS and a databases such as Mysql or Postgres.

Rachel,
In my experience (mostly a very large national enterprise with a
well-established IT group) you're right, it's the (Unix/Windows/...)
system administrators who undertake such tasks.

I once found myself pursuing an almost identical question, but along
network lines instead: Who does the network configuration and
administration of your server infrastructure? The network administration
team or the system administration team?

I've seen very few cases where it isn't the system admins that do the
network configuration of the server infrastructure, yet nearly all
network reconfigurations are prompted as part of projects initiated and
owned by the network administration team.

Who manages and configures your DNS? Your resolv.conf? Is name
resolution an application service or a network service?

The system adminstrators usually end up performing an entirely menial
task almost completely under the direction of the network
administrators. Why?

Allowing the network admin team to change the IP address of an ethernet
port on your server usually requires giving the router jocks your root
password, something you'd never do.

I've found that the allocation of responsibilities has generally fallen,
somewhat pragmatically perhaps, along the lines of 'who can actually do
it?' ie, along identity/access-control/authority lines. If you have the
root password you can install and configure software and hence usually
end up doing it, because to allow others to do it necessitates providing
them with the very thing you preciously preserve: your control over the
relevant piece of infrastructure.

I have a case in mind that further illustrates the potential truth of
this: mainframe environments. In mainframe environments the system
security and rights allocation mechanisms are usually sophisticated
enough and fine-grained enough that you can grant the network
administration team sufficient rights for them to undertake their
relevant activities, without giving them rights to completely
reconfigure everything. In these environments the division of labour is
often more rational.

Virtual machine environments will see a shift I think, especially in the
scenarios in which you're most interested: application configuration.
When it becomes more common for individual or clusters of related
applications to be hosted in virtual hosts rather than within the same
single shared operating system instance it will be easier (read:
safer|more likely) for responsibilities within a particular virtual host
to be shared with the people actually responsible for the applications
running within them. The application support teams may be given more
power over their applications and the system administration team may
voluntarily relinquish the exclusivity of rights that they currently
preserve.

What you're describing isn't an apt-get artefact, it's a
distribution/release one.

I don't see how it differs from:

Install Debian version 3 release 1.
Select development task
apt-get install get-text

If you're managing Debian machines, you either rely on the standard
releases, or you do your own. That way you can precisely reproduce a
particular configuration from a particular time.

 Sure apt-get is cute (easy, nice, etc), but ...

apt-get will work cutely, easily, nicely etcely from whatever you point
it at. If you point it at the unstable distribution it'll change over
time. If you point it at a known configuration it'll always install
that, every time.

 Are there any issues in doing this?

The only problems you might encounter are one of general annoyance on 
your part after a few goes of rebooting your machine just to use your 
webcam :)


.. and that while you're running with a non-SMP kernel you'll only be 
using one of your presumed more-than-one CPUs. Which probably won't 
really be a problem at all.


I actually have a QuickCam Pro 4000 too. I haven't tried very hard to

If it's any consolation you're not alone in experiencing difficulty with
