F29: authselect with nis losing mdns4_minimal [NOTFOUND=return],
breaks printing
by Terry Barnaby
Having updated to F29 from F27 (which seems to be generally working well
:) ), I have one issue with our systems due to the new authselect system.
When I enable the nis (YP) system for logins the /etc/nsswitch.conf file
loses the "mdns4_minimal [NOTFOUND=return]" for hosts searches. One
result of this is that when you try and add a printer (at least using
KDE/PLASMA), and the printer is discovered using DNS_SD, then at the
final adding stage the printer is not actually added (does not appear in
the list of printers etc). There are no error messages to the user
(always a bad failing of Fedora/Linux/MsWindows in general), but looking
under the hood it is due to part of the CUPS system not being able to
resolve the <hostname>.local network host address as mdns4_minimal is
not being used.
I have been setting up nis using: "authconfig --enablenis
--nisdomain=<domain> --nisserver=<server> --update". This appears to
call authselect as:
"authselect select nis with-fingerprint with-silent-lastlog --force"
So should I be using a different, direct, authselect command to fix
this, or is it a bug in the authselect system ?

Yes, works fine. Thanks

So both those sections have to be put into 99-zap.conf ?

Not only did Mate not start, I could not find a way out other than
killing the power.
Nothing in all the logs I could read, but .xsession-errors had an entry
reading something
like "environment could not be loaded". I have since deleted that
user, and created another which works fine. The only difference was
allowing the GUI to
create a user group the same as the user name. The user was named guest,
and it created
a group called guest and made the user part of it.

That's what I suspected, and I guess to be expected if Mate couldn't load
the proper environment.
It's a mystery to me why the second attempt was sucessfull while the first
wasn't.
A related question: how do I set up Fedora to allow the alt-sysreq REISUB
to kill the session? And I also thought alt-ctrl-backspace killed the
xserver. It
doesn't for me.
Still finding my way around Fedora after having been gone for a year or two.

problems creating a new user
by Frank McCormick
I am running Fedora 29 with the Mate desktop. This morning I tried
creating a
new user to check out a problem. After logging out and logging in again
with the new users name and password, I was presented with a blank screen
with just the mouse cursor visible.
I deleted that user then created a second new user but got the
same results.
I checked the new users directory after logging in with my regular
account, and there are just a few sub directories but I noticed that
there was no /Desktop. no /Pictures etc.
Has anybody else experienced this problem ?
Any suggestions?

Software for streaming audio or video over LAN
by Marko Vojinovic
Hello everybody,
Huh, it's been a while... :-)
I'm interested in your suggestions/experience regarding multimedia
tools for streaming audio and possibly also video via LAN (mostly WiFi),
played back on multiple client machines, with little to no latency.
You know --- say I want to play some music on my laptop in the living
room, and I want to hear the same thing play on another computer in the
kitchen, and another one in the garage, etc... ;-)
Ideally, it should be low-latency, in the sense that playback should be
synchronized across devices. Like, if two machines are playing in two
rooms, and I'm in the hallway in between them, I shouldn't hear any
offset between the two playbacks.
I'm looking for Linux-centric solutions in general, but mostly from
Fedora or CentOS land. It should do audio, while video would probably
depend on the WiFi speed, I guess.
So far, I've been thinking of a DIY combination of bash scripts and
mplayer, but I guess it's easier to try out something that someone
already made, before I end up mocking up the whole thing from scratch
myself.
Looking for any pointers and suggestions (including keywords for
google). ;-)
TIA, :-)

OT: Fedora Interactive boot option...
by Michael D. Setzer II
Long ago Redhat and early Fedora versions had the option of pressing the
letter i at boot to have it request for loading of the individual kernel options.
Used it long ago, but haven't seen it for a long time, and search show the old
one, but not how it was done, or if it was something only on the redhat.
Have a project that I have handled since 2004, and it works fine using
kernel.org source code to build on versions up to my current Fedora 28
system.
Have an user with an IBM Thinkpad t440p and it freezes with all 5 of the
kernels that are included, plus with safe mode options, and debug options.
Originally, the last message was about ata8 device. Built a special kernel
with all ata modules removed, and lock just showed a different last message,
so am thinking it is what loads next that is freezing.
Looked thru the kernel options, and don't see anything about an interactive
option.
Just wondering if someone might know how that interactive boot process was
done.
Thanks.

Problems with Fedora 29 on my hardware
by Mr Brian Domenick
Hi,
I have a 15 inch HP Spectre 360 running Fedora 28, it runs fine using
nouveau video and wireless works. I tried to upgrade to Fedora 29. After
upgrade with dnf it is fairly broken. Everything came up on the surface,
but it was sluggish and sudo bash was very slow to authenticate and it
was popping multiple oops messages at the top of the screen. I then did
a fresh install of Fedora 29. This seemed to mostly work and no
immediate sluggishness once done. I then upgraded using dnf to the
latest software. This is where the bad behavior came from. After dnf
upgrade sluggishness on sudo again as opposed to instantaneous
authentication before dnf, wifi could now not be shut off. Oops messages
on top of screen and complaining about one of the cpu's in dmesg and
also complaining about Noveau. Wifi became broken and gnome network
manager to shut it off wouldn't do anything. The icon showed as up with
signal but a browser wouldn't work. When it popped up report screen to
report kernel problem it was populated with no info and all you could
really do was close it. Funny thing is I did a fresh install of 29 first
on my Samsung laptop which has strictly intel graphics and different
wireless and everything works 100% on that laptop.
Thanks, any thoughts would be appreciated, I put Fedora 28 back on the
HP and its fine with all the latest software there.
