Is there a distro pre-configured to install and run as a tor exit node?

Reece Arnott — 2013-05-22T11:19:17

I'm thinking about setting up a spare machine as a tor exit node and 
wondering which distro would be best to use as a base. Is there one 
already set up to run tor as an exit node which just has an install 
wizard or something?

(Or is it something that we should want to make a bit harder to do so 
you have to explicity commit to doing it?)

Power off after a certain time of inactivity in Ubuntu (using the activiation of a screensaver to do it)

Reece Arnott — 2013-05-22T09:38:14

Rob was asking for a way to save power by turning off machines that had 
been inactive for a certain number of hours in Ubuntu.

The key thing to realise is that sensing inactivity is what screensavers 
do so... sudo apt-get install xscreensaver if it isn't already installed 
and do the following:

1) create an executable script file from the text file shown here: 
https://gist.github.com/chrisyco/988104 (this is a wrapper to give you 
the options to suspend, hibernate, restart, or shutdown). This is 
optional if you are only going to ever want to shutdown.

2) Run xscreensaver-demo to create a ~/.xscreensaver prefs file if it 
doesn't already exist.

3) Edit the ~/.xscreensaver file.

The important thing is to insert the following line immediately under 
the line that says "programs:       \":
"Shutdown"     /absolute/path/to/power.sh shutdown \n\

The other options below can either be set while you're editing the file 
anyway, or via the GUI by running xscreensaver-demo:
timeout:    2:00:00 # This is the time of inactivity to wait hh:mm:ss
mode:        one # So only one screensaver is run. Note that if you ever 
set this back to cycle through random screensavers you should take out 
the above Shutdown screensaver :-)
selected:    0 #which screensaver is run, if the shutdown script is the 
first one listed under programs then it will be screensaver 0

If you are *only* going to shutdown you don't need to power.sh script, 
instead you can replace the reference to it above with the following line:
"Shutdown" dbus-send --system --print-reply 
--dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager 
org.freedesktop.ConsoleKit.Manager.Stop \n\

(I have tested this on Ubuntu 13.04 and it works. There may be minor 
variations in the older versions so YMMV)

Copying large files to a thumb drive?

Worik Stanton — 2013-05-17T00:38:00

I have a 32 gig thumb drive that I want to put HD videos on to play on
my TV.  (So far the best way I have found to

All works well except that the 5GB files do not copy happily.  At about
4GB the copy process fails complaining the file is to large, or it fails
silently.

I have tried drag and drop in Nautilus, the cp command and the dd
command.  I was about to use split, cp and cat but if some one has a
reason this is happening it could speed things up remarkably.

I am wondering if another file system might help.  According to mount it
is vfat, the drive I am copying the files from is fuseblk (not sure what
that is).

Any ideas?

DNS resolution on local network

Bob Brown — 2013-05-12T08:12:10

Hi,

A little while ago I installed a Debian server and called it "riwaka". It
is a bare bones install - only OpenSSH is installed onto it. I chose DHCP
for the network and it was assigned an IP of 10.1.1.13 on my LAN. It's
wired but it shares the same network space as wireless clients via my Orcon
Genius router.

I noticed on my Ubuntu laptop I could "ping riwaka" and I get a response
from it. On a Windows PC through it can't resolve "riwaka". Both the Ubuntu
and Windows PC's are DHCP-configured.

At first I figured that it was the router doing the name resolution as it
as the DNS server that is specified in the DHCP response but in the router
config it lists DHCP clients of which "riwaka" is notably absent:

10.1.1.2 name=android_b41ab12268964a9a
10.1.1.3 name=android-fafb23eb66e2912b
10.1.1.4 name=GuruBobs-iPod
10.1.1.5 name=android-5b740b7e8555ac05
10.1.1.7 name=toshtop
10.1.1.8 name=
10.1.1.6 name=Loopys-iPod
10.1.1.9 name=squee
10.1.1.10 name=SnOOpS-iPhone
10.1.1.12 name=OPOHOPC
10.1.1.15 name=PAVILION
10.1.1.19 name=hpbook
10.1.1.20 name=Opoho-PC

Presumably this is a list of DHCP clients that have been seen at some point
so they can be consistently given the same IP address.

Anyway - my question is - how come my Ubuntu machine can resolve "riwaka"
to 10.1.1.13?

Cheers,

- Bob -

Debian release tea party

Alex King — 2013-05-04T22:52:22

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I'm having a Debian release tea-party, if you want to chat about Debian
or anything related on a rainy day, come on up and join me at 3pm.

What: Debian release tea-party
Where: 60 Helensburgh Road, Wakari
When: 3-5pm today, Sunday.

RSVP appreciated.

You may know that today is the planned release date when testing
(wheezy) becomes the new stable version (7.0).  Due to our timezone, I
suspect it may not actually be released by 3pm, but we can celebrate
anyway.  If we run out of interesting conversation, we can listen to
National Radio or something (broadband is dodgy so youtube is
disappointing.)

Not much snack food here so bring your own if you want.

Some would say it's short notice, but it's more than 14400 seconds, so I
don't want any complaints :)

Cheers,
Alex

Free distros for new users

Danyl Strype — 2013-05-02T05:04:44

Kia ora koutou

I've tried a few more distros since Jan. I've been working my way
through the handful of distros endorsed by the FSF, to see if any of
them are usable as a day-to-day desktop OS. some of them are pretty
much useless, or at least so raw that they only usable by confident
GNU/Linux geeks:
http://tinyurl.com/bp3affg

Trisquel is the pick of the bunch so far. I've had a few minor niggles
with it on my netbook, but I'm looking forward to testing it on my
desktop when I get home.

I've also been looking into distros which are built around the
Enlightenment desktop. The only one I've actually tried so far is
Bodhi, which I see as more of a proof-of-concept distro than a
production one at this stage. I do like what I've seen of
Enlightenment so far though, it's leaner than XFCE (which was already
starting to bloat the last time I tried it as well as being ugly and
confusing), and gives LXDE a run for its money in performance and
stability, as well as being prettier than the LXDE distros I've tried
(Peppermint, Lubuntu, Triquel-Mini). Again, I'm looking forward to
trying it out on the desktop.

I feel some hesitation to bring this topic up again. I think that's an
undesirable chilling effect of the original discussion being framed as
a "flamewar". My posts on the subject may not have been "non-violent"
enough for Alex' needs, but I feel I made more effort than some to
maintain a neutral tone, and to back up my arguments.

Alex, I accept that "unethical" is a judgement, that's why I qualified
it by inserting the words "I believe" immediately before it, rather
than stating it as a self-evident fact. Also, I believe I stated my
needs in the email that started the whole discussion. I need Ubuntu to
regain my trust by owning the trademarks to their own name, making an
effort to be more responsive to their developer and user community,
and dealing with the UbuntuOne and Amazon-lens issues (I went into
detail in later emails about how I felt those needs would best be
met). Failing that, I need a new GNU/Linux distro to replace Ubuntu.

Restoring apt cache

Worik Stanton — 2013-04-15T22:00:53

My laptop will not boot.  I have been trying to get its HDMI output working
and something awful happened and now it will not boot. Oh dear, how sad, I
can cope. I have my bootable USB stick so can recover.

But I am a long way from a decent internet connection so do not want to
reinstall all my software over the net.  I have managed to burn my
/var/cache/apt onto a DVD (that was not easy) and I would like to know can
I expect to reinstall, which will stomp that cache(?), and copy the
cache/apt into the fresh file system and will those packages be available
to me without having to download again?

It seems to me that it should, but it is the first time I have tried.  I
know my /home directories will endure over reinstalling from my stick, but
the /var hierarchy? And if not I do not know if there is more I need to do
to copy my old packages over.

Since my last install (I reinstalled Ubuntu in the hope HDMI would work
better from there) I have not cleared the cache.

cheers
W

squid config puzzle

Craig Knights — 2013-04-11T22:33:59

OK,  I'm doing something silly..

I'm trying to time restrict a proxy..

this from my squid.conf

acl BOARDERS_ON_AFTER_SCHOOL time MTWTF 15:30-23:00
acl BOARDERS_ON_BEFORE_SCHOOL time MTWTF 07:00-08:30
acl BOARDERS_ON_WEEKENDS time SA 07:00-23:00


http_access deny !BOARDERS_ON_AFTER_SCHOOL
http_access deny !BOARDERS_ON_BEFORE_SCHOOL
http_access deny !BOARDERS_ON_WEEKENDS

but the proxy still goes... and it shouldn't

where's my logic failing?

hmmm, thanks,

Adding someone to a group

Geoff Barkman — 2013-04-03T02:46:34

Hi There
If I want to add someone to a group in Ubuntu 12.04 (and most other
linuxes) I type

addgroup geoff audio

To add myself to the audio group.

Now if in a terminal I type "groups", it shows up the groups I am in... but
not the new group until I log out and back in again... or reboot.

Does anyone know of a way that I can add myself to a group to save having
to logout? So the group membership shows up straight away. If I have to
type some other command to refresh things it doesn't worry me.

off topic. electronics project

greig corlett — 2013-03-28T21:56:19

Hi all

a bit off topic but im sure there is some electronics enthusiasts on here.

I am in the process of building a micro hydro generator from an old smart
drive washing machine.  i have rewired the stator to give an output voltage
between 60 and 120v depending on speed and mostly load.  I need to build a
regulator which will charge a 48v battery bank and be capable of around
5-7A or about 250w.

I was hoping to be able to use a 3 terminal regulator like the lm317 with
current boost transistors but since this regulator has a max voltage of 37v
would not be suitable.

Is the another similar regulator which is capable of the voltages and can i
use boost transistors in the same way with the higher voltage/ power
required.

Thanks guys for your help it will be very much appreciated.

Greig

Hi all
Geoff and I are involved in the Silverpeaks Country Music club. The club
has the domain silverpeaks.org.nz. We want to have a couple of email
addresses e.g. newsletters< at >silverpeaks.org.nz. Is it possible to set up a

do you go about organising it?

Any other suggestions?

Book on IT failures Dangerous Enthusiasms

"...Prof Gauld ... also spoke about the troubled teacher payroll
Novopay, saying the saga had renewed interest in his book on IT

rounding errors in the points of the triangles - bad game engine design 
- or maybe just due to bad scene design).
