No internet on resume
by Ben Flood
Hello, I am having a problem with Fedora 27 KDE, when I suspend and resume
I have no internet, and there is an error in dmesg about which I get a
notification: do_IRQ: 5.37 No irq handler for vector
This did not always happen. I first noticed it in kernel 4.15.3, and it
stopped happening in 4.15.4, but then upon release of 4.15.6 I noticed it
again, but now, reverting to 4.15.4 does not stop it.
Would greatly appreciate if someone knows how to fix this.

IPv6 assistance
by Chris Caudle
I am looking for some help getting IPv6 configured properly on a Fedora 27
system.
I have one system which was installed fresh with Fedora 27, that system is
working properly, it receives both IPv4 and IPv6 addresses assigned by my
router (running latest LEDE release).
I have a second system which receives the expected IPv4 address but does
not receive an IPv6 address.
I notice that on the working system NetworkManager shows two instances of
dhcp client:
$ systemctl status NetworkManager
● NetworkManager.service - Network Manager
Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service;
enabled; vendor preset: enabled)
...
CGroup: /system.slice/NetworkManager.service
├─10930 /usr/sbin/NetworkManager --no-daemon
├─10991 /sbin/dhclient -d -q -sf
/usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-enp0s25.pid
-lf /var/lib/Netwo
└─11106 /sbin/dhclient -d -q -6 -N -sf
/usr/libexec/nm-dhcp-helper -pf /var/run/dhclient6-enp0s25.pid
-lf /var/li
On the system with no working IPv6 address the second entry which begins
"/sbin/dhclient -d -q -6" is not present:
CGroup: /system.slice/NetworkManager.service
├─9804 /usr/sbin/NetworkManager --no-daemon
├─9872 /sbin/dhclient -d -q -sf
/usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-enp3s4f0.pid
-lf /var/lib/Netwo
└─9875 /sbin/dhclient -d -q -sf
/usr/libexec/nm-dhcp-helper -pf /var/run/dhclient-enp3s4f1.pid
-lf /var/lib/Netwo
(In both cases the dhclient arguments are truncated, ran off the edge of
my terminal)
This is from the ifcfg file for the primary interface, it seems to have
the correct IPv6 settings, at least I do not see anything obviously
different than the working system:
# IPv4 settings
BOOTPROTO=dhcp
# Not sure this is needed, doc says PPP only
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
PEERDNS=yes
PEERROUTES=yes
# IPv6 settings
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
#IPV6_ADDR_GEN_MODE=stable-privacy
#IPV6_PRIVACY=rfc3041
#IPV6_PRIVACY_PREFER_PUBLIC_IP=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
DHCPV6C=yes
# Firewall settings
ZONE=FedoraWorkstation
One thing odd that I note in the messages file:
NetworkManager[9804]: <warn> [1520343008.2540] dhcp6 (enp3s4f1): request
timed out
NetworkManager[9804]: <info> [1520343008.2542] dhcp6 (enp3s4f1): state
changed unknown -> timeout
NetworkManager[9804]: <info> [1520343008.2638] dhcp6 (enp3s4f1): canceled
DHCP transaction, DHCP client pid 9916
NetworkManager[9804]: <info> [1520343008.2638] dhcp6 (enp3s4f1): state
changed timeout -> done
enp3s4f1 is a secondary interface, I may not have the DHCPv6 server setup
correctly to hand out addresses on that interface. I see no dhcp6 messages
for enp3s4f0. Is there a bug that would cause dhcp6 client to stop if the
first interface timed out rather than moving on to the next interface?
thanks for any help,

video card questions
by François Patte
Bonjour,
1- When there are two video cards on a computer, an integrated one and
another one, how can we know which video card is used by the system?
2- I have a laptop with an ATI/AMD card, is there a proprietary driver
available on fedora (like this exists for nvidia cards).
Thank you.

How to install the new Video Download Helper Companion App and have
Firefox recognize it
by Temlakos
Everyone:
Firefox crippled most of its extensions beginning with Version 57. (Why
they borrowed technology from Google, I'll never know.) The developers
of the Video Download Helper responded by creating a Companion Application.
I have tried installing that application dozens of times. But /Firefox
refuses to recognize it/. And without that recognition, VDH will not
download most videos from YouTube. (Was that the idea?)
Has anyone gotten that companion app to work? If so, how may I do it?

should /etc/issue.net be installed without telnet-server?
by Robert P. J. Day
(another of those "dang, i never noticed that before" questions
inspired by teaching last week.)
currently, my fedora 27 system has the file /etc/issue.net, which i
casually explained last week was what was printed when you tried to
connect to the system over the network (as opposed to /etc/issue). but
while my fedora system has the man page "man -s 5 issue", it does
*not* have "man -s 5 issue.net".
i thought this was odd since both of the files appear to be
installed by the same package:
$ rpm -qf /etc/issue
fedora-release-27-1.noarch
$ rpm -qf /etc/issue.net
fedora-release-27-1.noarch
$
so why would the man pages not similarly both be there? well,
the man page for /etc/issue comes from here:
$ rpm -qf /usr/share/man/man5/issue.5.gz
man-pages-4.12-1.fc27.noarch
$
while a yum query points out where the man page for /etc/issue.net
would come from:
$ yum whatprovides /usr/share/man/man5/issue.net.5.gz
telnet-server-1:0.17-71.fc27.x86_64 : The server program for the
Telnet remote login protocol
Repo : fedora
Matched from:
Filename : /usr/share/man/man5/issue.net.5.gz
i guess that makes sense since i can see from online that man page,
which explains that /etc/issue.net is related to telnet only:
https://linux.die.net/man/5/issue.net
which specifically claims, "The file /etc/issue.net is a text file
which contains a message or system identification to be printed before
the login prompt of a telnet session."
so, apparently, /etc/issue.net is telnet-specific? i had no idea. in
any event, it still seems odd to generically install the file
/etc/issue.net, while the man page for the same file needs the
installation of telnet-server to show up. is this worth a bugzilla
filing, or is there something else happening here i don't understand?

is there any value to pruning /udev in /etc/updatedb.conf?
by Robert P. J. Day
just noticed in /etc/updatedb.conf in F27, the snippet:
PRUNEPATHS = "... /udev ..."
not sure if /udev ever existed in fedora, but i think it's safe to
say, it's not there now and probably won't be any time in the near
future. and even though it doesn't *hurt* to have extraneous directory
names in that list, is there any compelling reason to keep it there?
