Latest VLC version
by Mark
Is it just for me that VLC has stopped working with latest upgrade?
When I open a media file it will play the audio but not the video and
in the log there is
vlc.desktop[22216]: [00007f5298001080] xcb vout display error: window
not available
Totem doesn't have any problem playing the same media files. My VLC
version is 3.0.0-0.28.git20170622.fc25

Screensaver Anomaly in F25
by Craig Lanning
I did an upgrade from F24 to F25.
Everything seems to be working fine.
I use xscreensaver instead of gnome-screensaver with a Gnome desktop.
I have noticed that the timer for the screensaver is not being reset
when I type or use the mouse. I can be using the machine and the
screensaver will activate and then deactivate (since I'm typing or
using the mouse).
Has anyone else noticed this kind of behavior?
Is this something with xscreensaver or is the timer reset somewhere
else?

CIA Outlaw Country attack against CentOS / Rhel (and Fedora?) Is
this credible?
by stan
Wikileaks released a document about an attack against CentOS / Rhel.
https://wikileaks.org/vault7/#OutlawCountry
Here's the text, there are some docs there also.
OutlawCountry
29 June, 2017
Today, June 29th 2017, WikiLeaks publishes documents from the
OutlawCountry project of the CIA that targets computers running the
Linux operating system. OutlawCountry allows for the redirection of all
outbound network traffic on the target computer to CIA controlled
machines for ex- and infiltration purposes. The malware consists of a
kernel module that creates a hidden netfilter table on a Linux target;
with knowledge of the table name, an operator can create rules that
take precedence over existing netfilter/iptables rules and are
concealed from an user or even system administrator.
The installation and persistence method of the malware is not described
in detail in the document; an operator will have to rely on the
available CIA exploits and backdoors to inject the kernel module into a
target operating system. OutlawCountry v1.0 contains one kernel module
for 64-bit CentOS/RHEL 6.x; this module will only work with default
kernels. Also, OutlawCountry v1.0 only supports adding covert DNAT
rules to the PREROUTING chain.
My first take is that this doesn't represent a very serious threat. Do
you disagree?

Writing a systemd service file
by Alex
Hi,
I'm trying to write a service file for a daemon and having some
problems. I believe the issue is with the ability to give the process
write and read access to parts of the filesystem which appear to
somehow be restricted.
The daemon is the Avira virus scanner, which runs under amavisd-new.
The daemon's home directory is
/usr/local/savapi-sdk-linux_glibc24_x86_64, and it needs write access
in the modules directory.
The daemon can run as root or as the amavis user. It drops its
privileges to the amavis user after starting anyway.
Here is what I have so far:
# cat /etc/systemd/system/savapi.service
[Unit]
Description=Avira Antivirus SDK
Documentation=http://www.ijs.si/software/amavisd/#doc
After=network.target
Wants=clamd(a)amavisd.service
Wants=postfix.service
RequiresMountsFor="/usr/local/savapi-sdk-linux_glibc24_x86_64"
[Service]
Type=forking
User=amavis
Group=amavis
PIDFile=/var/run/amavisd/savapi.pid
ExecStart=/var/spool/amavisd/savapi.sh start
ExecReload=/var/spool/amavisd/savapi.sh reload
Restart=on-failure
#PrivateTmp=
PrivateDevices=false
CapabilityBoundingSet=
ProtectSystem=full
ProtectHome=true
[Install]
WantedBy=multi-user.target
I've specified "RequiresMountsFor", which I understood could be used
to provide access to parts of the filesystem. I've also disabled
PrivateTmp and PrivateDevices.
The ExecStart script just spawns the savapi daemon:
#!/bin/bash
cd /usr/local/savapi-sdk-linux_glibc24_x86_64/bin
./savapi --config=savapi.conf &
When I attempt to start the service, journalctl -xe shows me:
Validation failed for option 'ModulesDir' with value
'/usr/local/savapi-sdk-linux_glibc24_x86_64/modules'. Path cannot be
accessed (no write permission).
ModulesDir is /usr/local/savapi-sdk-linux_glibc24_x86_64/modules
When I run the script manually as root or as the amavis user, it runs
successfully.
I think the problem is that I don't understand how systemd processes
access the filesystem and the restrictions on permissions.
Any ideas greatly appreciated.
Thanks,
Alex

Keyboard problems.
by George R Goffe
Hi,
I'm running Fedora 27 x86_64 (rawhide) and have noticed a problem in text windows with Firefox.
The problem exists in both the FF released version AND the FF beta version. It could be Firefox.
The problem exists with KDE and WindowMaker as the desktop manager.
What I'm seeing:
I have the caps lock key mapped to the ctrl key so when I type ALL caps I have to hold down the shift key. When I try to insert a space between words I have to release the shift key, otherwise the space is ignored. This used to work but since I reinstalled this system the keyboard is acting strangely. This behavior plus certain other letters seem to want to generate a cedilla or an accent grave or accent acute or an umlaut. There are a few other characters that behave similarly. Coincidentally I started getting messages about python forcing "PYTHONCOERCECLOCALE=0". Maybe this is not related to this problem, I can't tell. Could this be a LOCALE issue?
I can't tell if this is a bug or just a UFU (User Foul Up). Any thoughts/hints/tips/suggestions would be gratefully accepted.
Thanks,
George...
