nc missing option -z
by Suvayu Ali
Hi,
I used to use netcat to check if a particular host is up or if I have
internet connection before I run a few scripts. I would use the -z
option in particular. But now I see that has been removed:
$ nc -z imap.gmail.com 993 && sync-my-email.sh
ncat: invalid option -- 'z'
Here is the excerpt from the old manual page:
-z Specifies that nc should just scan for listening daemons, without
sending any data to them. It is an error to use this option in
conjunction with the -l option.
Any ideas what happened to it? What can I use as replacement?
Thanks for any ideas.

Alternatives to Theme Font size changer Firefox plugin?
by Sam Varshavchik
The popular theme font size changer Firefox plugin,
https://addons.mozilla.org/en-US/firefox/addon/theme-font-size-changer/, no
longer supports Linux.
The default Firefox font size is too small for people with poor eyesight. As
far as I can tell, the only thing that official "Firefox themes" do is set a
background image for the UI. As Benny Hill would say, biiiiiiiiiiiiig …deal.
The top-ranked comment on that extension page suggests hacking "userChrome-
example.css" in ~/.mozilla/firefox.
$ find ~/.mozilla/firefox -name userChrome-example.css -print
$
There goes that idea.
Googling around the only other suggestion I found was to hack
layout.css.devPixelsPerPx setting in about:config. All that did, apparently,
was making the Firefox UI elements themselves bigger, but their font size –
the menu and the URL bar – remained exactly the same.
Anyone has other suggestions?

Taskbar Panel in Plasma Won't Autohide
by Stephen Morris
Hi,
I am trying to get the Taskbar Panel to autohide, but when I click on
the options button in the panel, the left, right and center options are
permanently highlighted but seem to function in terms of moving the
indicator that reflects which option is active. Also the 'Always
Visible', 'Auto Hide', 'Windows can Cover' and 'Windows go Below'
options are also permanently highlighted but selecting the 2nd or 3rd
option does nothing. It appears these options are highlighted because
the colour scheme I am using, which is forget-me-not thinks they are
push buttons.
Does anyone know why these don't work anymore in Fedora 23? I am using
Breeze for the Windows Style and Windows Decorations themes.
regards,
Steve

F21: Thunderbird insists on calling Fedora list messages junk!
by William Mattison
Good afternoon,
Most messages received from this fedora list are labelled junk by
Thunderbird. This is even though I whitelisted "From" =
"users-request(a)lists.fedoraproject.org". Actually, I have this problem
both in my Fedora-21 and my windows-7 systems. Any ideas? Surely
messages from this list are not junk!
thanks,
Bill.

enp0s8 not configured notification popups every few minutes (annoying)
by Kenneth Wolcott
Hi;
enp0s8 not configured notification popups every few minutes (annoying)
I just installed Fedora Live 64-bit KDE as a VirtualBox Guest OS.
I want to have two VirtualBox ethernet interfaces:
One for the vm to "see" outwards (NAT Network) and
Two for me to ssh into it (Host-only) so that I'm not forced to use
the console.
Every few minutes (it seems like every few seconds), I get a
notification popup that states that enp0s8 is not configured and then
a notification popup that it is being disabled.
How do I configure my outgoing ethernet interface?
I used to edit a file called something like /etc/network*/interface
and then I could change the default DHCP setting to be static and the
default disabled (off) setting to be enabled (on).
How does one do that kind of stuff now?
Is that a systemd thing?
Thanks,
Ken Wolcott

installing via VNC over ipv6
by Chris Murphy
This suggests installation using vnc over ipv6 is supported:
https://fedoraproject.org/wiki/Anaconda/Features/Ipv6OnlyInstallation
But when I use inst.vnc boot option, I get an text screen that says to
connect to an ipv4 address, an ipv6 address isn't listed. When I go to
a shell and use 'ip addr' there is a global ipv6 address, but no
formatting for tigervnc I've come up with will connect, it won't
connect:
vncviewer.desktop[12590]: CConn: unable connect to socket:
Invalid argument (22)
If I boot Fedora 23 Server on this same hardware, the 'ip addr'
address can be used successfully to ssh into the server, and also
point a browser to https://[ipv6]:9090 to reach the Cockpit interface
successfully.
root 1744 0.0 0.9 251060 36468 pts/0 Sl+ 03:29 0:00 Xvnc
:1 -depth 16 -br IdleTimeout=0 -auth /dev/null -once
DisconnectClients=false desktop=Fedora rawhide installation on host
10.0.0.15 SecurityTypes=None rfbauth=0
I can't tell if -InTransports needs to explicitly specify ipv6 for it
to work. But at this point I'm stumped and can't tell if it's user
error or a bug. And netstat isn't on non-live media apparently so I
don't have access to that while xvnc is running to see if it's
listening over something other than just an ipv4 address.

Balsa -
by Bob Goodwin
I have installed Balsa in this updated Fedora 23 computer, it runs but
will not connect to the mail server.
I can click on "check" and it appears to be checking for mail but
produces an error message ending in "ERR Invalid Command." I've been
through the account set up process again thinking I may have had a typo,
but still no luck.
Also after having run Balsa from a terminal I see the following:
(balsa:22220): Gtk-WARNING **: Failed to register client:
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
org.gnome.SessionManager was not provided by any .service files
** Message: init gpgme version 1.4.3
** Message: protocol OpenPGP: engine /usr/bin/gpg2 (home (null), version
2.1.11)
** Message: protocol CMS: engine /usr/bin/gpgsm (home (null), version

** Message: protocol GPGCONF: engine /usr/bin/gpgconf (home (null),

** Message: protocol UIServer: engine /home/bobg/.gnupg/S.uiserver (home
(null), version 1.0)
** Message: OpenPGP protocol supported
** Message: CMS protocol not supported, S/MIME will not work!
Network is available (Tue May 10 16:31:42 2016)
So "** Message: CMS protocol not supported, S/MIME will not work!" is
the problem?
Can I fix that? If so what must I do ...
I've tried this running both xfce and gnome in Fedora 23 and in a VM
with Fedora 24b, the result is always the same, I can't collect any mail
with balsa ... Same error message.
Any thoughts appreciated,
Bob

Dual boot
by Celso Viana
Hi all,
You know if you can dual boot with GPT and BIOS disks on the same machine?
/dev/sdb GPT -> Windows 10
/dev/sda BIOS -> Fedora 23 x64
The machine only starts with Windows; not appear the boot menu
Thanks!

I would have thought it was just css setup by whoever runs the
hyperkitty web site to make it looks like whatever they want.
If it is hard coded and not css, then hyperkitty needs a much
much bigger enhancement request :-).
