Hey all,
Does anyone have real-world experience of using linux's interface
bonding on public networks?
(In the bandwidth-aggregation mode, not the redundancy mode)
I was wondering how I could make the following setup work:
* Rent a VPS in Melbourne with four IP addresses
* Get four (or just two) ADSL connections wired up to home
* Have your VPS connect four VPN connections from itself back to each
of your home IPs.
* Bond all four interfaces together
* Create a fifth VPN connection, this time going over the
bonded-virtual-interface between VPS and home, and then configure your
home server to use that link as the default route?
It sounds pretty messy and I'm not sure it'd actually work in
practice; the routing tables would be hell to get right.
Are there any guides already out there?
Cheers,
Toby

As said, I had similar issues - and it is an Optus network.
For the case mentioned here, I would go with the commentary on the
mentioned page:
ITT: The evidence posted just indicates there's a fucked up router
somewhere in Telstra (or along the path) that's screwing with large
packets, nothing here proves Telstra monitoring.
Why it only affects some hosts? Because routing isn't the same for all
destinations.

I'm looking at buying a new tablet. It will mostly be for watching video,
Youtube and movies downloaded from the net, but as with most general purpose
computers it will get used for lots of other things.
The main options I'm considering now are the Google Nexus tablets. The Nexus
line seem to have good quality hardware, good specs, and reasonable prices.
They also should be easier to root if I want to run Ubuntu or something on
them later.
For tablets with 16G of RAM the Nexus 7 is $299 and the Nexus 10 is $469.
Currently the 32G Nexus 10 is out of stock so I'm mostly comparing the 16G
Nexus 7 with the Nexus 10, if I choose the Nexus 7 then I'll think about
whether it's worth paying for extra storage (probably will be given that
there's no SD card support).
Does anyone have any experience with them? What about comparing 10" and 7"
tablets generally? Obviously 10" is better for watching movies and a lot
better if more than one person is watching. 10" should also be better for
blogging.
Is the 10" tablet worth the extra $170 and losing the option of more storage
(or alternatively waiting for Google to get stock)?

Above are the Play Store and Wikipedia pages for the tablets in question.

Hi,
Linux distros using the apt package management system tend to cache
downloaded packages in /var/cache/apt/archives/
If you have many very similar machines set up, then you'll almost
certainly have a HTTP proxy cache setup for them to retrieve packages
through, to reduce huge duplication of downloads.
This essentially obsoletes the /var/cache/apt/archives, though. And
when you're running dozens of virtual machines, it'd be nice to avoid
storing all these duplicate files.
What's the right way to disable it?
I see I can adjust the max size and age via the
APT::Archives::Max{Age,Size} parameters, but what about just turning
it off altogether?
Cheers,
Toby
Hi All,
Want to disable UUID, and address hardware directly by device and
partition specs. Did it on my current system (~ 4 years ago), happy.
But see differences in files/contents in Trusty, and want your expert
advice, before I start changing things.
My knowledge is low. (Barely understand what I'm writing.) Can follow
clear simple step-by-step instructions, or grateful for links to same.
New system is Gigabyte MB, IntelCore i5 CPU, SATA HDD, dual booting on
64-bit Windoze plus just-released Trusty 64-bit Desktop.
Here's what I =would= do...
(1) Edit /etc/default/grub to remove the # at the start of line...
#GRUB_DISABLE_LINUX_UUID="true"
(2) Edit /usr/share/grub/grub-mkconfig_lib to comment out the 3 lines
starting...
if FS_UUID= (etc.)
... but that line doesn't exist in that file.
(3) Edit /etc/fstab and change very instance of UUID= (etc.) into the
corresponding drive and partition e.g. /dev/sda2
(4) Edit /etc/initramfs-tools/conf.d/resume and change UUID=RESUME=
(etc.) into the corresponding drive and partition e.g. /dev/sda2
(5) Run update-grub
(6) Then re-do all the above each time I do a kernel upgrade.
So please: Your advice, keeping to my original goal of
disabling/bypassing UUID. What am I forgetting? What am I doing wrong?
Thanks VERY much,

Recently python-iview stopped working because the ABC apparently started
sending unicode characters where the previous code didn't work.
The new python-iview in GIT depends on Version 3+ of Python and the
Debian/Wheezy Python build system doesn't seem designed for building that - or
at least it's well beyong my Python coding ability.
I used the below patch to convert the text in question to plain ASCII and make
the program work again (the change to the #! line isn't needed).
Note that the ABC doesn't want us to create archives of programs downloaded
from their web site. But if you do want to create such archives I can
recommend a BTRFS RAID-1 array of two cheap SATA disks for that purpose. 3TB
SATA disks are dirt cheap nowadays. The worst of the BTRFS problems I
described in my last LUV talk only occur when a filesystem is filled and a 3TB
RAID array isn't something you'll fill quickly.

Hi all,
I bought a Firefox phone.. and it does not connect to the Telstra network
(Optus works, btw, but I have a Telstra contract at the moment).
It works using WLAN.
However, I wanted to play with it anyway.. Do you know a way to connect it
to a PABX as Asterisk?
Regards
Peter
Hi,
I posted last year about a problem I was having with Linux's PPPoE
functionality in regards to a specific modem. At the time I put it
down to a dodgy modem and moved on, but now I've hit it on another
modem, and twice seems more than coincidence.
The problem is that path MTU detection seem to break when the "bad"
modems are involved. So the Linux box running pppoe is OK, because it
knows the interface has an mtu+mru of 1492, but masqueraded clients do
not.
You can work around the problem a bit, by having an iptables rule with
--clamp-mss-to-pmtu, but it's a kludge.. and importantly, only
required for two of these four modems. The other two work just fine
*with apparently identical configurations* (ie. LLC / bridged)
Can anyone think of a reason for this?
The rp-pppoe and other mailing lists offer tantalising hints that I'm
not alone, but sadly those threads do not lead to any solutions.
Modems that work:
* TP-Link TD-8817 (Trendchip chipset)
* Billion 7300RA (Trendchip chipset)
Modems that don't work:
* TP-Link TD-8840T (Trendchip)
* Billion 7800NL (Broadcom chipset)
We have a few Netgear ReadyNAS 104's, and they all crash under high iscsi load. They are being used to hold backups from a windows server, and the one I've been working on rarely gets through a single overnight backup.
I have ssh'd in and it seems that the iscsi backing store is a file sitting on a btrfs mount. The kernel is 3.0.101, which strikes me as a little old for running btrfs although I guess being an appliance they could well have backported everything from a newer more stable release. Or not, going on how much crashing it's doing.
I was planning on using netconsole to see if I could capture its dying gasp, but it's not compiled in and not built as a module.
A warranty claim is the obvious answer, but that's always a pain so I'm wondering if it's possible to work around the problem by tweaking some things.
Netgear are aware of the problem, and have asked things like how full is it getting so I guess they know about the btrfs limitations relating to running out of space. So far the only solution they have offered is to try the latest beta kernel and do yet another factory reset, which we've done.
Some info (abridged):
# mount
/dev/md127 on /data type btrfs (rw,noatime,nodiratime,nodatasum,space_cache)
/dev/md127 on /apps type btrfs (rw,noatime,nodiratime,nodatasum,space_cache)
/dev/md127 on /home type btrfs (rw,noatime,nodiratime,nodatasum,space_cache)
# uname -a
Linux RPCV-NAS1 3.0.101.RN_ARM.1 #1 Thu Mar 6 09:31:05 PST 2014 armv7l GNU/Linux
Any hints appreciated!
Thanks
James

From the beginning (many years ago) I have had problems with some DVD
drives not reading video DVD's correctly so these days I usually have 2 DVD
drives, and LG and either a HP or Pioneer DVD, if the disk wont work on one
it will (usually) work on the other.
Note: I do not have a TV or infact watch TV at all, I do though uses DVD's
for some entertainment, because of this it was worth my while to go to some
effort to watch DVD's.

errrrrrrrrr, lets put it this way.........
libdvdcss allows one to watch DVD's from different regions, its a
cryptographic cracking system so some distro's (Debian any way) do not
package it. For a long time I have sucessfully viewed zone 1, 3 and 4 DVD's
using this library.
The library is transparent in use if its present a player (eg xine) will
use it, if its not present it will of course not use it.
