Razer laptop Caps-lock key of the death
by Jeandet Alexis
Hi all,
I'm an happy Fedora user, I changed my laptop last year for a Razer
sealth blade.
Fedora/Linux works well except for the known caps-lock key which just
crash the whole system when pressed:
https://github.com/rolandguelle/razer-blade-stealth-linux#caps-lock-
crash
I tried to add XKBOPTIONS="ctrl:nocaps" in /etc/default/keyboard.
The thing is that this solution doesn't seems to work on Fedora, not
easy to find what to search on Google, it looks like
/etc/default/keyboard isn't right config file.
I'm using Gnome with Wayland. Any idea?
This issue/feature is quite fun to show to friends(looks like an auto-
destruct key) but quite annoying when you press caps-lock by mistake
:).
Yes getting it solved by Razer would be the best! But last time I asked
them something, I got:
"
Hi Alexis,
Thank you for contacting Razer Support.
At this time, Razer does not officially support Linux. I am sorry for
the inconvenience this might cause you.
Have a nice Monday!
"
Best regards,
Alexis.

Restart Xorg server and Noveau driver
by Javier Perez
Hi.
Xorg froze while playing a game with wine. Only the mouse worked (not even
the keyboard). I had to hard reboot.
Checking out the logs (journalctl) I saw repetitive nouveau errors.
(sorry, not at home, else I´d post them).
Other times I have been able to ssh into my machine and everything else is
working. I did not try this time (my secondary machine is down for the
moment).
My question is: How can I restart the Xorg server and/or the nouveau
driver?
If I could ssh into the system, I think I could just restart both and not
have to reboot the whole thing. It is more annoying that anything else
because the machine boots fast, but still I think it should not be
necessary.
Just polishing my skills.
Thanks

[LEARNING OUTCOME] Wi-Fi WPA Hacking Tool is Totally Useless on New
Wireless Routers
by Turritopsis Dohrnii Teo En Ming
Hi,
I am sharing my learning outcomes.
Recently I downloaded Kali Linux 64-bit Version 2018.1 and ran it on
my HP laptop with the integrated Intel Dual Band Wireless-AC 8260
Wireless Network Card.
I wanted to test if I could hack the Wi-Fi WPA password on Ruckus R700
Access Point (AP) and the Aztech DSL8900GR(AC) Wireless Router. So I
started using the Reaver WPA cracking tool.
I understand that the Reaver tool works because there is a bug with
Wi-Fi Protected Setup (WPS).
I have no luck with Reaver on the Ruckus R700 Access Point. After
running Reaver, I found out that WPS is permanently disabled on the
Ruckus R700 AP with no option to turn it back on at all. Hence It is
not possible to hack the WPA password on Ruckus R700 AP.
Understanding that I couldn't do anything further with Ruckus R700 AP,
I proceeded to test Reaver on the Aztech DSL8900GR(AC) wireless
router. In this case, I also found out that WPS is disabled by default
on the Aztech wireless router. Reaver will not be useful at all if WPS
is disabled. But there is an option to enable WPS. So I enabled WPS in
the Aztech wireless router configuration page. And continued testing
with Reaver. But because Aztech wireless router has the rate limiting
security feature, brute force password attacks will be very slow and
probably take forever. The rate limiting security feature on the
Aztech wireless router is meant to slow you down when you are brute
forcing the WPS pin.
So here is my conclusion: Reaver Wi-Fi WPA hacking tool is totally
useless on new wireless routers which have the WPS disabled or have
implemented a fix for the WPS bug. Are there any other WPA cracking
tools which I can use in my educational learning journey? Please
advise.

Troubleshooting random hangs
by Suvayu Ali
Hi,
I have been having random hangs on my new Ryzen workstation (Ryzen 5
2400G + B350 mobo). My hardware is supposedly properly supported on
4.15+ kernels. But I have been unable to boot with any of the ones in
the repo.
That said, I can boot with older kernels, but the desktop hangs
randomly. When I say hang, I mean it freezes, and my only recourse is
to reset my computer. I have tried to login remotely, but then I get
"No route to host" from ssh. Looking at the journal, I can't figure
out what is causing these hangs. If someone could have a look, that
would be wonderful.
Logs from the last two hangs:

dnf Upgrade Produces GPG Error
by Stephen Morris
Hi,
I've just attempted to do a sudo dnf upgrade to install the 343
updates that are available, and after downloading all the packages it
got a GPG error and terminated. Has anyone else seen this and is able to
provide some guidance on what I need to look at to identify why?
[SKIPPED] vulkan-filesystem-1.1.70.0-1.fc27.noarch.rpm: Already downloaded
[SKIPPED] xdg-utils-1.1.2-4.fc27.noarch.rpm: Already downloaded

Package flash-plugin-29.0.0.113-1.fc27.x86_64.rpm is not signed
The downloaded packages were saved in cache until the next successful

You can remove cached packages by executing 'dnf clean packages'.

Wow, KVM is great :-)
by Raman Gupta
For my Windows workloads on Linux, I've been paying VMWare for years for their Workstation product so I can run Windows programs like Visual Studio and Quicken. Recently, having some issues with my Windows VM (VMWare using massive amounts of memory and CPU beyond the VM allocation, and causing random latency on my desktop), I thought the time was finally right to try out virsh and KVM again. Converting the VMWare image to KVM worked flawlessly via `qemu-image convert`, and then after a whole bunch of hassles getting the right virtio drivers and guest agent installed and working, the VM is running great. It's running flawlessly, just as fast or faster than my VMWare image, and way more efficient on memory and CPU. And I don't need to taint my kernel to run it.
I do have some follow-up questions though:
1) It seems the networking is not quite as straightforward as VMWare for a single-VM use case. VMWare can run the VM in bridge mode, so that it appears to the rest of my LAN as just another PC. Host-guest, and guest-other networking works perfectly. In contrast, in virsh, it looks like none of the 3 options are as transparent: https://wiki.libvirt.org/page/VirtualNetworking. Running in the default NAT mode, I have two issues:
a) My guest DNS does not transparently work to access my LAN -- only the Internet. The docs @ https://libvirt.org/formatnetwork.html do not provide any guidance for configuring DNS settings. I want to forward requests to the dnsmasq running on the host system.
b) What is the best way to configure my host system to be able to see the NATed IP addresses in the virtual network?
(Fedora 27, fully updated)
Thanks!

fixfiles / restorecon with selinux disabled
by Berend De Schouwer
Hi,
I'm struggling to relabel a root filesystem correctly for SELinux.
I've got a system where I've had to copy (rsync) / to a new harddrive.
I then changed the UUIDs in /etc/fstab, and the system is booting from
the new harddrive. So the labels went missing.
The system does not allow logins if SELinux is enabled, because some
files (including systemd-user-session) are labelled incorrectly.
I've tried various ways to get it back, but fixfiles relabel,
restorecon -vR / require SELinux enabled, and if I enable it I can't
log in to run restorecon.
I've tried /.autorelabel but it appears to be ignored. I've checked
some files with 'ls -laZ'.
Any ideas?
