It scans the OS for malware, but not anything else. (Like my collection of
obvious malware that I want identified.)

ClamAV does a better job scanning a local filesystem. (But it won't store
the viruses into a tree structure for my collection.)

It sounds like something has the file or directory open, but has also
deleted it. (So the process is still holding onto the file, but the system
does not show it since it is marked as deleted.) Sometimes programs will
do this as a way to secure the data from the rest of the OS.

Have you tried rebooting to see if the process and/or kernel will release
the space? I am not certain of lsof will show what process is hanging onto
it.

du -h --max-depth=1 /

You can then look in the directory using the most space with the same
command until you find what you want. You might need to run it under sudo
to avoid the "cannot access directory" error messages.

When I moved to Alaska I had been going to a private school. My reading
skills were very good, but my math skills we not. My mother hired a
math tutor for me from the University of Alaska. She figured the best
method to get me interested in math was by teaching me Fortran. I was
in 4th grade at the time. Spent a lot of time in the computer lab from
then on.

That is one of the first lessons you learn if you learned to type on a
Royal manual typewriter. Looking for 0 and O is another.

Found an obscure bug in a Perl program that I started over 20 years

There was a problem with the early version of those drives. It was

I have a couple of those drives and they work great.

You think I don't know that?  I spent 8 years scheduling speakers

If needs be we can investigate different venues. It is nice to have a

[PLUG] Epson V600 Photo scanner on Fedora 26 -- HowTo

[Alan]

I have gotten the Epson v600 Photo scanner working on Fedora 26. It is
not that hard once you know the one secret step.

First, download the rpm packages. (There are also debian packages and a
similar trick will work for Debian based distros as well.)

First make sure you have libtool and libtool-ltdl installed.

The packages can be found at: http://support.epson.net/linux/en/iscan_c
.html

Download the package bundle for your OS. (32 or 64 bit.) untar/unzip
the bundle. It will create a subdirectory with an install script. Run
it and it will install 3-4 packages.

Now for the nasty bit.

cd into either /usr/lib 9if you are using 32 bit) or /usr/lib64 (for 64
bit).

Look for what version of libltdl.so is installed. On Fedora 26 it is
libltdl.so.7.3.1.

Create a symlink to cover up the lack of proper support for modern
distros.

sudo ln -s /usr/lib64/libltdl.so.7.3.1 /usr/lib64/libltdl.so.3

You can now test with "iscan" and see if it works.

My only concern would be making sure the underlying file system was case

Actually not always...

Depends on the device and the cable.

There are "charge only" cables that will not transmit data.

If the device is made by Samsung, you need to make sure that it has the
correct cable. Some micro usb cables have a resistor in the end that the
Samsung device wants. (Part of the cable spec I believe.)

If it is a usb-c cable you need to verify if it is to spec. (There was a
Google engineer that reviewed all the cables on Amazon.) Not everything
was made correctly.

I am considering doing a talk on Qubes OS. It is very interesting, but the

Qubes is a high security OS where everything runs under a hypervisor.

And on a separate note, the Mac OS X spell checker is the most annoying

What model scanner?

I have an Epson V600 Photo scanner and it required special drivers from
Epson. It took a little hackery to get the binary blobs to recognise.
(Symlinks to differening .so versions for libraries.) Once I did that
XSane would just see the scanner. Xsane looks for available scanners on
load.

Check the scanner manufacturer site for drivers.

There is a tool in Windows to resize partitions. It is much faster than
using gparted.

https://tweakhound.com/2013/01/02/how-to-resize-your-windows-8-partition/

Windows demands to be the first OS on the drive. Install it first, then
resize the partitions leaving enough space for Linux, then install Linux.
Be careful not to wipe the laptop recovery partitions. Some laptops get
upset if those are gone. Linux installs understand what to do with Windows
install and add them to the grub menu.

I had to do this with my Windows 7 laptop. It was annoying, but it worked.

Check the permissions on your .ssh directory. It should be 700. It is
trying to access the key, it just can't find it. That could be
permissions.

That sounds like a different talk. There are disclosure rules for
vulnerabilities that cover this sort of thing. I can do that talk at a
later date.

After getting both of the hardware devices, the talk may be for a
general audience. These are starting to be used for all sorts of general
purpose web sites. Might even be used on facebook at this point. (I
don't use it, but I might set up a bogus account to test this.)

I will know more the farther I get into the project.

The torrent hangs retrieving the metadata. It looks like there are no
seeders for the torrent. (I need to find a client that has good debugging
for torrents.) It could be that there is a IPv6 address that is not
routing, but I am not sure. I get the same hang behavior. The magnet link
format for this one is odd. It does not use a direct tracker address.
Judging by their forums, the way they handle their torrents is not very
straightforward. I wish I had a good answer, but I don't.

Does Ktorrent support magnet links?  They only torrent links I am seeing
on their site are magnet links and not all clients support them.

Transmission should work fine. (It does on the link I tested.)

I have a Lenovo W540. That is about as new as you can get. (It is less

Keyboard is good. Laptop was really expensive. I use an external mouse

on seeing the external mouse. The trackpad works, I just hate trackpads.

[PLUG] A quick summary of Open Source Bridge in Portland

[Alan Niven]

I just wanted to let PLUG subscriber know that the Open Source Bridge 
last week was awesome and highly recommend. Many sessions covering many 
day including an ad hoc Friday set. The food my the best of any 
conference and drew from Portland food carts/caterers. The price was 
right at $300 for all four days including the food and 8 hours of 
volunteer work got your in for free. For the next 30 days you can sign 
up for next year for only $150.

The most surprising thing to me was how nice, friendly and helpful 
everyone was. I hadn't put together that people interested in open 
source would understand and embody the principles that by working 
together we can build and fix the things we need an make a better world. 
At some point here will be videos of all the main session available on 
the Open Source Bridge

The X86 port is ready for prime time. It is on shipping phones in the UK,
China, and India.  There is a translation layer that will convert ARM to
x86 on the fly. (I have seen it run on many test phones and tablets in the
lab on the current version of Android.)

If you are going to run a virtual emulation of Android, you should use the
one that comes with the Android SDK. It builds for either ARM emulation or
X86.

Phones on x86 will be in the US soon. (It takes longer to get a phone to
market in the US, as well as some carrier related issues.) How soon I am
not certain. I live too far in the future and they don't tell me when it
ships.

I may be able to do a presentation on X86 and Android, but I would have to
clear it through legal first. (I have signed many NDAs.)

In the next couple of months I hope to be building an Intel i7 system with

to 64gigs of ram.

If anything is Linux compatible, that should be.  (And if it isn't, it

I have a fixed IP with CenturyLink.  Getting a fixed IP was a bitch, but
using Linux actually helped get to the right people to get it done.  (I
told them I run my own mail server. Had to turn on port 25 on their web
page config and everything worked fine.)

The problem i have with them is they started capping service.  As of
February you will get nastygrams if you use "too much" bandwidth. (They
just cut and pasted what Comcast did with their service.)  They have the
same bandwidth cap for 12mbs as it is for 40mbs.  I calculated that at
40mbs you could reach your bandwidth restriction for the month in 14
hours.  (I cut my service back to 12mbs when I found that out. Not going
to pay $50+ a month for little or no benefit.)

Buying your own modem is a good idea. My Q1000 overheats too often.

[PLUG] Netgear GS116 warranty

[Alan]

My GS116 switch just died 5-days ago, altho I had a similar Netgear 
giga switch die about 6-months ago. Not to mention the power supply 
to my Infrant-Netgear NV+ file server going up in smoke about 2-months ago.

Netgear does a great job of making it hard to use there warranty, but 
eventually come thru. First you should make sure your device is 
registered at there website. Then you need to call they're hard to 
find phone number 888-638-4327 (use extension #4 for tech support.) 
You'll get an operator who will give you a case number then put you 
into a queue to talk to an support engineer. Recently when I got to 
this stage they're hold system timed out after 15 minutes and put me 
into voice mail where I left my number and email. After 4-days of no 
response I had to call again, this time a was able to describe the 
problem to an engineer, after following the previous process. The 
engineer approved my failure and but me on hold to speak to the RMA 
specialist who after verifying serial number, name and address, case 
number etc again and another on hold period, gave me the RMA number. 
He waited on the line while I confirmed the confirming email he sent 
me and the I got to select one of three RMA programs, from free 
(after I send back the unit with the specified documentation to a 
next day air delivery of a replacement unit and pre-paid return for 
about $50. Since I had already replace the unit with a Trendnet 
TEG-160WS smart switch in the intervening time, I went with the 
cheapest approach for about $12.

A similar winding path to replacement was experience with Netgear on 
the fired power supply with the NV+ except I paid the big bucks for 
the next day air. I've notice that a lot of warranties, including the 
lifetime GS116 don't include the power supply, which under normal 
condition it the most like part to die, altho a well designed unit 
should last more than ten years. Cheap capacitors from China seem to 
have cut that lifetime to less than half. Hopefully cap quality will 
increase with manufacturing experience and buyer demand.

Good Luck

The problem with CentOS is that it is based off of RHEL. Red Hat has taken
some steps to make it harder for CentOS from using their RPMs. (Like
having the kernel source as one large tarball instead of clean source and
patches.)

I have two big problems with CentOS.

The versions used are OLD. (As they are in RHEL.)  There are features in
SSH I would like to use on my home system, but the version used by CentOS
is about 5 years old.  If I wanted to use out of date, bitrotten software
I would install Debian.

The packages are quite limited.  I was going to install a program that
needed a pile of Haskell packages and most of them did not exist for
CentOS. Compiling the packages would have meant updating a number of other
packages just to get it to build. If I wanted to go through that headache
I would just install something that is current and upgrade every six
months.

Ubuntu has long term support for some of their versions, but they are
Debian based and I really have no love for the Debian package manager.

I have a T61 laptop at work. I have expanded it up to 4 gigs ram and a

QWest blocks port 25 if you use dhcp.

If you have a fixed IP address you can turn off port 25 blocking by
going to qwest.net and change the settings for your account.

One other problem you may have is that your outgoing address needs to
resolve correctly for your domain. (I had this problem. The CentOS
version of Postfix kept setting my domain as
"localhost.clueserver.org".) Look at the masquerade rules to fix this.

It really depends on where you live. Are you in Qwestland or Verison 
territory?

Depending on where you live you may be able to get DSL/Fiber with faster 
speeds. I have been told it is possible to get just DSL without land line, 
but I think it depends on the carrier.

Speeds vary due to location and carrier. Look on their web site and it 
will tell you what speeds are available for your address.

You really want to use the kernel source from your distro and not the
generic source. Each distro makes changes to their kernels that may or may
not be needed by userspace tools.

BTW, you do not need to recompile the kernel to disable ipv6.

In /etc/modules.d/aliases make the following additions/changes:

 alias ipv6 off
 alias net-pf-10 off

Once you reboot, ipv6 will no longer load.

[Alan]

NOTE: The meeting time and location has changed again.

PLUG Advanced Topics
December 16th, 2009 
7pm - 9pm

Roots Organic Brewing
1520 Southeast 7th Avenue
Portland, OR 97214-3568
(503) 235-7668

Using DRBD to Build High-Availability Clusters on Commodity Hardware

Charlie Schluting of LINBIT will explain how DRBD works and how people
currently use it, with enough information to get you started building
your own clusters.

DRBD stands for Distributed Replicated Block Device, and as the name
implies, allows you to replicate block devices over TCP. DRBD is
extremely flexible due to the fact it is a block device, and as such is
used in a variety of situations. At the most basic level, you can
replicate data between two servers to provide synchronously replicated
storage redundancy for either failover or disaster recovery purposes. In
active/active mode, you can also run GFS, OCFS2, or other clustered file
systems.

Topics that will be covered:
- How it works, history, and future exciting news regarding mainline
kernel inclusion
- How it is used: HA-iSCSI, HA-NFS, Virtualization, Apache, Samba, etc.
- Cluster Resource Manager options and recommendations, and news about
the confusing changes in the Linux-HA / Clusterlabs communities.

And the majority of the time will be spent on:
- Example cluster configuration: hardware setup, installation and
configuration, and cluster manager integration.

Come with questions!

[PLUG] [ANNOUNCEMENT] PLUG Advanced Topics November 19th, 2009 **NEW NIGHT and LOCATION**

[Alan]

[We're back! Sorry for the downtime. Personal issues ate my brain.]

We have a new location, a new night, and an old time.

Michael Dexter  is helping me keep things organized
and helping with planing.  He will help getting speakers and the like.

PLUG Advanced Topics
November 19th 2009
7pm - 9pm

Location: Club 915
  915 SW 2nd
  Portland, OR

Club 915 is a block south and across the street from where Jax used to be.
Big stone building. Can't miss it.

Topic:  Backporting Linux kernel Drivers with Git
Speaker:  Alan Olsen 
  Intel Corp.

Description:
The talk will be a demonstration on how to use git to assist in
back-porting drivers from one kernel version to another.  It will include
merging patches, determining what patches are part of the driver you are
backporting, generating patches, etc. I will also have a quick intro to
some of the git concepts I will be using.

Note: This is a new venue.  It is closer to the Max Line than Roots. It
also has more space.  We will see how it works out.

If the device has the Intel Pousbou chipset in it, then you have to deal
with some proprietary drivers. Ubuntu has support for it. Moblin does as
well. Not much else has it at this point.

Weird. Fedora 11 has been pretty stable for me. (And my laptop has known

Try running memtest86 on your machine and see if your memory is stable.

[PLUG] ANNOUNCEMENT: PLUG Advanced Topics April 15th 2009

[Alan]

Advanced Topics
April 15th, 2009 7pm - 9pm-ish

Location:   Roots Organic Brewery
1520 SE 7TH
Portland, Oregon

Topic:  Server Sky - Data Centers in Orbit
Speaker:Keith Lofstrom

Large data may soon consume 50MW or more of electrical energy.  The EPA
estimated US data center power consumption in 2006 at 60 billion
kilowatt
hours, or 1.5% of total US power consumption, and predicts a doubling by
2011. This will have huge environmental, social, and economic
consequences
unless we find alternative ways to power our digital economy.

Server sky is a proposal to build large dispersed arrays of ultralight
solar powered server satellites and launch them into 6400km equatorial
earth orbits, between the inner and outer Van Allen belts.   There is
room in these orbits for billions of server-sats.

A 30 gram server-sat consists of a thinned 12 inch solar cell, with
power efficient processors, solid state memory, and microwave
transceivers bonded to the edges. Thousands of server-sats position
themselves into dozens of dispersed three dimensional arrays (hundreds
of meters on a side) using light pressure for thrust and liquid-crystal
shutters for trimtab steering.  A server-sat array acts as a large
phased array antenna, permitting it to steer thousands of communication
beams at receiving stations and communities under its position in orbit,
handing off communication and control to the server-sat arrays that
follow it in orbit.

Earth can return to what it is good at – green and growing things –
while
space can be filled with gray and computing things.  More information at
http://www.server-sky.com

Comcast has an immediate significant problem for me.  That is, lack of
freedom.  Freedom is a major advantage of Free Software, and it is a
major advantage of open access networks.  Comcast is largely free to
do whatever they want with rates and restrictions.  Yes, they are
sometimes fast.  But also, yes, they block useful things at a whim.
Compared to 100 Mbps symmetric fiber you can get in Tokyo for
$11/month, they are FAIL.

John> As for speed, at one time they were throttling torrents, [...]

Clear is not going to be a good choice if you plan to run torrents.
They use a medium (the airwaves) that has a finite capacity, and they
are likely to be aggressive about keeping it relatively free, to enable
them to get the oversell ratios to the point where it's profitable for
them.

John> [...] Recently Clear had a table at PSU with a couple employees,

They were probably not Clear employees.  Clear has been extremely open
to resellers.  Many, many podunk little computer consultancies, ISPs,
cell phone dealers, etc have been signing up to resell Clear.  You see
"Clear people" everywhere.  Few to none of them are Clear employees,
any more than the cell phone kiosk dudes/dudettes at the mall are
Verizon or AT&T employees.  I don't know what the resale deal is, but
I suspect they get a cut of the subscription fee.

Clear has had a lot of money dumped into it.  Intel alone gave it
something on the order of $1.5 Billion (somewhat amusingly, the devices
that Clear is using on the network are not using Intel radios, but
broadcom and motorola).  Comcast, Sprint and others have also invested
in Clear.  Right now, Clear is aggressively advertising to get
subscribers.

We (Personal Telco) have been told that Clear can be used to backhaul
PTP hotspots.  If that is verified by experience, then they can be
counted as sharing-friendly and we'll identify them as such to
potential node hosts.

Right now, there are no linux drivers for the Clear USB WiMax device.
So mobile WiMax use for linux (and Mac, I think still) is
problematic.  You can take the Clear Home modem thingie with you, and
it uses a standard 12V power supply and has ethernet ports so drivers
are not an issue with it.  Just a bit bulky, is all.

That is, in summary, what I know about Clear.  Eventually (when device
drivers appear and work reliably), they might be a good choice for
mobile Linux and Mac users.  Right now they might be a good
alternative to Comcast in places you can't get DSL or where DSL
service is crappy.  But ultimately, for fixed-location service, I
think open-access (by which I mean where you have an wide choice of
ISP and Terms of Service) fiber is the way to go.

I am currently considering canceling.  A bunch of real life events has
been distracting me from getting a speaker.  The room change is not
helping.

Anyone have suggestions?

Re: [PLUG] March AT location?

[Alan Olsen]

I do not have a speaker for the next AT. (Life and work have eaten my
brain.)

Not certain what people want to do. Try for fourth Wednesday? Heavy
drinking? Something else?

Re: [PLUG] AT at Roots followup and schedule glitch

[Alan Olsen]

Is another night available? Tuesday or Thursday?

I asked Sarah (Roots Event Coordinator) to give me some feedback
