[clug] Raspberry Pi Zero: US$5 for bare board

1. Does this change anything? Is Ardunio still a great deal?

2. The Raspberry is a commercial operation.
    As there better value alternatives? More options than the Beagle boards?

Board $5 [out of stock]

Budget pack $30

	• A Broadcom BCM2835 application processor
		• 1GHz ARM11 core (40% faster than Raspberry Pi 1)
	• 512MB of LPDDR2 SDRAM

	• A mini-HDMI socket for 1080p60 video output
	• Micro-USB sockets for data and power
	• An unpopulated 40-pin GPIO header
		• Identical pinout to Model A+/B+/2B

[clug] November - IPv6 using it on the modern internet - Bob Edwards


Canberra Linux Users Group Meeting - 26th November 2015

 Date:          26 November 2015 (Fourth Thursday of the month)


 Time:          18:15 - 18:55

 Abstract:     It's BeerSIG time!
               'What's BeerSIG?' I hear you ask! BeerSIG is a social
               gathering, and an opportunity to get together with
               like minded people and share a social pint
               or two before the meeting.

 Location:     Wig and Pen, Llewellyn Hall, Canberra School of Music
               Look for the table with a stuffed toy penguin


 Time:         19:00 - 21:00 (or when it finishes)

 Speaker:      Bob Edwards

 Abstract:     IPv6 was going to replace IPv4 and "fix" all problems with
               the internet from exhausted address space to letting people 
               have thousands of addressable devvices each. Have you tried
               using an IPv6 only system online?

[clug] Anyone using Seagate SMR dives [6GB & 8GB, 3.5" 'Archive']??

MSY had Seagate 3.5” Archive drives listed when I looked at the Price List today [don’t often check].

Anyone got any Real World experience of them, including “Didn’t buy because I read the reviews”?
Can’t use in RAID arrays from the review I read.

[clug] Shell scripting problem using 'process substitution' [ >( pipeline ) ]

Following a line problem, I have a monitoring script running on a low-power Linux box that uses wget to get
the stats page from my (ADSL) Netcomm router/firewall.
The script runs continuously and I rsync the file back to another machine.
"Just because", the monitoring script only ever appends to the file, so it gets large.

Looking at the data, I could break the file into “per day” files, and then analyse them.
It’s easier admin to leave everything in the one file and just select the day/s I want to process.
[Manually stop / start the monitor & break-out the days into their own files. Can’t do this solely on the
destination m/c because of ‘rsync’.]

I found myself running the same grep (for the day) twice over the long file & counting different things, and
wondered if there was a way to use a pipeline. There is no performance reason to do this - doesn’t take much
time, it’s “just because” :)
[A problem I had encountered for work a few times and never came up with a solution I liked.]

I’ve got two variants below that work, but I’m not happy with the result…
To see something useful, the ">( process )” have to write to STDERR (or /dev/tty).

If I pipe the output of the ‘inner’ count to STDOUT, then it gets sucked up by the next step in the main
pipeline and I won’t see it.

I _could_ play with file descriptors (clone STDOUT to FD-3 for ‘inner processes' and STDOUT of last
process to /dev/null at the end), but that seems a bit clumsy.

The fragment as it is now can’t be ‘just used’ in a pipeline because it doesn’t output to STDOUT
[throws it away], but STDERR.

Anyone do anything like this?

Any suggestions?

[clug] Poweroff doesn't work, it just reboots

     Has anyone experienced this issue where you select "Shutdown" and
the computer shuts down and the reboots instead of staying shut down,
and know of a suitable fix?

I am using Debian Jessie with the Xfce interface on one computer, and
the other has a minimal installation, that is no GUI. Both have this

Below are links to similar issues, with varying and odd suggestions
for a solution.

dpkg --purge kexec-tools

After reading this bug report [1] I added xhci_hcd.quirks=262144 to my
/etc/default/grub boot options.

This list configuration changed somewhere along the way and now

[clug] IPSEC (racoon) - ip route and SNAT assistance


I was wondering if anyone could assist me in getting a VPN tunnel to work
with a specific vendor which requires our VPN end points to be Public IP
addresses to go down a ipsec tunnel.

Lets say my Site (call it site-A) connects to other site (called Site-B)

Phase 1 is working fine.

I have two other systems which are not on the same subnet in the public IP
address space needing to go down this tunnel. However they are on the same
subnet with their private IP addresses (

Site B is fixed to only communicate to my public IP address (unable to
change this)

With some magic of ip route and iptables I believe I can route traffic from
my Machines under the public IP space to hop to the VPN private IP address
and be advertised as the src of the Public IP address when entering the

I know I can see by using an ip route <dest address> via <private VPN gw
address> src <my private IP address> would get the packet over
and using some sort of iptables -t nat -s <IP1> -d <IP2> -j SNAT --to <IP3>
is needed to delivery the packet down the tunnel.

I was wondering is anyone want to assist in getting things working for me?

I am hitting a wall knowing there is an obvious solution but I think I am

[clug] Off topic : Hackfest? Help or group contact details

Hi all, 

First of all sorry for this off topic post. 

Secondly I seem to remember a few posts on this list about a group,  something like Hackfest, that get
together to create electronic solutions to problems. 

My problem is that I have a very good, mostly fox proof, lockup for my chooks but I keep forgetting to lock them
up at night. My chooks were killed by a fox last Sunday night due to my lack of diligence. I don't want to get
more chooks until I can make something that automatically locks the chooks in at night and lets them out in
the morning. This would also be useful when I go away for a few days. 

I thought that some people on this list may be able to help me by either helping me design an automatic locking
and opening system or point me to a group that could help. 

Thanks in advance for any help.

[clug] Adam Baxter turbo talk <at> Ruxcon

Just wanted to share with the list that Adam Baxter gave an awesome
Turbo Talk (aka. Lightning Talk) at Ruxcon 2015 yesterday on gaining
root on an embedded Linux router device he purchased from Amazon.

The Ruxcon Turbo Talk organisers gave it "best talk" props ("not
that Turbo Talks are a competition", or are they?).

We'll have to persuade him to present it again at CLUG sometime
(although it only goes for a bit over 2 minutes).

Good work, Adam!

Bob Edwards.
