Hoping someone can throw light on this issue for a Linux newbie.
I'm running Ubuntu Server 12.04LTS and accessing the web via DHCP client
on a Netgear router/modem.
DNS service is provided through Dyndns.org
Basic website is accompanied by a Moodle site which is the main focus of
my operation. (support learning and teaching for U3A group)
All features and functions of Moodle are operative however email cannot
be sent or received. My previous experience with Moodle sites has not
relied on this DNS service and I have no idea what influence their
operation has on the handling of email.
If someone is familiar with all the links in this chain I would
appreciate some explicit advice.

On behalf of the *linux.conf.au 2014* team we are pleased to announce that
we have now started accepting early bird registrations.
According to Luke John, organising director, “The start of registration
represents the culmination of a lot of groundwork in planning for the
conference and it's a real milestone to be at this point in the process”,
“While there's still a lot to do, it's really starting to take shape now,
and I'm quietly confident that we've got a great line up of speakers and
topics and we are looking forward to an awesome conference”.
Paul Del Fante also chipped in to offer encouragement for those of you who
may feel a bit daunted by the distances. “It's Perth, it's Summer, we've
got a fantastic Linux conference on, warm beaches, balmy evenings, city
life, so come on over and share in our hospitality”.
The *linux.conf.au 2014* early bird registrations will be open till
2013/10/13, but are for a limited number of places and may close earlier
before we move on to the formal registration period, and we'd please ask
anyone who registers during this time to keep an eye out for any minor
issues or inconsistencies you come across.

Very early in the boot process, before the getty etc are fired up, I want
to fire up a process that talks over a full tty. What state it leaves the
console after it has finished is irrelevant - the process will finish with
I've had some element of success with openvt and screen (and running stty
sane in the subshell), but they're not particularly neat, and neither of
them propogate the exit value from the last command executed.
And my google fu is still failing me. Anyone any idea of a simple .c
program or the like that can initialise the tty into a semi-sane state and
talking over /dev/tty will do the expected thing? Running 'tty' this
early in the process tells me my tty device is /dev/console, but it
doesn't behave like a tty, in that rlwrap fails to do the expected thing
'rlwrap: Could not open /dev/tty: No such device or address'
(yes, /dev/tty is c 5 0)

That is true and definitely adds a layer.
Whether it is SELinux or containers - you rely on kernel code. Both
can have vulnerabilities.
SELinux is sharing the same name space with the rest of the system -
so you can reach other services, files etc. by misconfiguration.
People are lazy. The easiest way to get it work: allow everything for all.
I just help someone to have a test instance of a website.
There is a form writing data to one DB table (contact):
What do I see: GRANT ALL for db.* for user anyone (no password).

That's correct. But I still need additional layers being reliable,
otherwise it just adds a false sense of security.
At least in the server I rather rely on containers.
The FreeBSD jail implementation is completely done in the kernel
without further userland configuration.
According to Robert Watson he needed to change/add ca. 600 lines to
implement it, that is clearly easier to audit than the complex SELinux
At the same time it contains services pretty well.
As for Androids etc. - I would not trust them as far as I can throw them.
I wonder whether people are interested in a "connection fob" which is
giving you the functionality of a wireless modem, phone connectivity
and GSM, as well as contains and hides devices behind it.
It would improve our security and privacy significantly if that little
thing is open-source and has practical mechanical switches to
enable/disable connectivity, I believe.
Behind it, a phone is a (IP) phone and a tablet is a tablet and a
computer a computer and they all do not rely on plenty of closed
source drivers etc because they do not need to implement the
connectivity functions anymore. And the data exchenge between them is
The connection fob would be the most useful "smartwatch" I could imagine.

I think one of the major drawbacks of a fibre to the node network is
Mike Quigley, CEO of NBN Co, said one of the advantages of a GPON
network is the distribution hub requires no electronics. He used an
example in the United States where a hub was "under water and full of
mud" and it continued to function while the fire department used a
high pressure hose to clean it. Without electronics, the
distribution hub does not require a power supply, nor a battery for
power outages. In a GPON network only the local exchanges housing the
fibre access nodes and the equipment on premises require a power supply.
If Turnbull has his way, it means:
hubs with electronics (optical to fibre converters) close to the house
The converters need power, so it adds additional power lines and other
and a need to shelter the electronics against every kind of weather.
This will in fact increase the costs of the NBN while decreasing
bandwidth and reliability. The savings argument is a dud.
Recently I read a print of an IEEE paper which is coming to the same
result. (sorry, cannot find a reference anymore)
Only politicians without any knowledge could really argue in favour of
fibre to the node in dominantly suburban Australia.
What do folks feel works well for them for a running a local apt-cache?
I want to avoid having to download apt packages for my various Kubuntu
machines for speed rather than quota reasons.

Hi luv-main (or is that now la-luv-main?),
Would someone who was there like to give the list a summary of what happened at tonight's AGM? I couldn't attend but I'm interested in the outcome.
