“*ERROR* pipe is still busy with an old pageflip”
by Lawrence D'Oliveiro
I’ve been hitting an occasional display freeze that matches this
description <http://forums.gentoo.org/viewtopic-p-7675146.html>. Looks
like a known problem with the 3.16 kernel. I thought things had got
better with a system update I did 11 days ago, but this afternoon the
freeze recurred.
Unlike the previous times, killing all my user processes succeeded in
unfreezing the display, so I was able to log in again without rebooting.

Inkscape Version 0.91 Released
by Peter Reutemann
"Four years since the last major Inkscape release, now news is out
about version 0.91 of this powerful vector drawing and painting tool.
The main reason for the multi-year delay is that they've switched from
their old custom rendering engine to using Cairo now, improving their
support for open source standards. This release also adds symbol
libraries and support for Visio stencils, cross platform WMF and EMF
import and export, a native Windows 64-bit build, scads of bug fixes,
and much more. Check out the full release notes for more information
about what has changed, or just jump right todownloading your package
for Windows, Linux, or Mac OS X."

Samba issues
by David Nicholls
Hi guys. I am having an issue with my fresh samba setup.
I built a 14.04.1 LTS Ubuntu server and set up a single mount point
(/media/data) and pointed 3 separate internal hard drives to it (eg it
contains directories "music_drive", "tv_drive" & "movie_drive").
I turned "/media/data" into a samba share.
Annoyingly permissions look fine but I cannot seem to be able to either see
the share on my network from other machines or connect to it. Even using
the servers IP address.
Any advice? Or am I just missing something obvious.
My config is below.
samba.conf
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
#======================= Global Settings =======================

## Browsing/Identification ###
# Change this to the workgroup/NT-domain name your Samba server will part of
# server string is the equivalent of the NT Description field
# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no
# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
; wins server = w.x.y.z
# This will prevent nmbd to search for NetBIOS names through DNS.
#### Networking ####
# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0
# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes
#### Debugging/Accounting ####
# This tells Samba to use a separate log file for each machine
# that connects
# Cap the size of the individual log files (in KiB).
# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no
# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
# Do something sensible when Samba crashes: mail the admin a backtrace
####### Authentication #######
# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.
# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.
# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<
kahan(a)informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
########## Domains ###########
#

# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set

# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)

# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)

# It specifies the location of a user's home directory (from the client
# point of view)
; logon drive = H:
# logon home = \\%N\%U
# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
; logon script = logon.cmd
# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos

Dell Continues Shipping Fresh Linux Laptops
by Peter Reutemann
"In its latest move, Dell will be bringing Ubuntu 14.04 LTS to its
top-of-the-line Precision M3800 workstation laptop and the latest
model of the Dell XPS 13. Both systems will be running Ubuntu 14.04.1.
According to Barton George, Dell's Director of Developer Programs,
programmers had been asking for a better, officially-supported Ubuntu
developer laptop. This came about from a combination of the efforts of
Dell software engineer Jared Dominguez and enthusiastic feedback.
Specs of M3800: 15.6" LCD @ 3840x2160, Intel i7 quad core CPU, NVIDIA
Quadro GPU, up to 16 GB RAM. The bad news is, as Dominguez explained
on his blog, this version of the M3800 doesn't support its built-in
Thunderbolt 2 port out of the box. However, thanks to the
hardware-enablement stack in Ubuntu, starting with upcoming Ubuntu
14.04.2, you will be able to upgrade your kernel to add some
Thunderbolt support."

FSF-Endorsed Libreboot X200 Laptop Comes With Intel's AMT Removed
by Peter Reutemann
'"The Free Software Foundation has announced its endorsement of the
Libreboot X200, a refurbished Lenovo ThinkPad X200 sold by Gluglug.
The laptop ships with 100% free software and firmware, including the
FSF's endorsed Trisquel GNU/Linux and Libreboot. One of the biggest
challenges overcome in achieving FSF's Respects Your Freedom
certification was the complete removal of Intel's ME and AMT firmware.
The AMT is a controversial proprietary backdoor technology that allows
remote access to a machine even when it is powered off. Quoting from
the press release: "The ME and its extension, AMT, are serious
security issues on modern Intel hardware and one of the main obstacles
preventing most Intel based systems from being liberated by users. On
most systems, it is extremely difficult to remove, and nearly
impossible to replace. Libreboot X200 is the first system where it has
actually been removed, permanently," said Gluglug Founder and CEO,
Francis Rowe."'

Georgia Institute of Technology Researchers Bridge the Airgap
by Peter Reutemann
"Hacked has a piece about Georgia Institute of Technology researchers
keylogging from a distance using the electromagnetic radiation of
CPUs. They can reportedly do this from up to 6 meters away. In this
video, using two Ubuntu laptops, they demonstrate that keystrokes are
easily interpreted with the software they have developed. In their
white paper they talk about the need for more research in this area so
that hardware and software manufacturers will be able to develop more
secure devices. For now, Farraday cages don't seem as crazy as they
used to, or do they?"

Mozilla Dusts Off Old Servers, Lights Up Tor Relays
by Peter Reutemann
"According to The Register, "Mozilla has given the Tor network a
capacity kick with the launch of 14 relays that will help distribute
user traffic. Engineers working under the Foundation's Polaris Project
inked in November pulled Mozilla's spare and decommissioned hardware
out of the cupboard for dedicated use in the Tor network. It included
a pair of Juniper EX4200 switches and three HP SL170zG6 (48GB ram,
2*Xeon L5640, 2*1Gbps NIC) servers, along with a dedicated existing IP
transit provider (2 X 10Gbps). French Mozilla engineer Arzhel Younsi
(@xionoxfr) said its network was designed to fall no lower than half
of its network capacity in the event of maintenance or failure. The
Polaris initiative was a effort of Mozilla, the Tor Project and the
Centre for Democracy and Technology to help build more privacy
controls into technology."
