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.

install.img
by CLOSE Dave
I need a copy of the install.img file for Fedora 20. It doesn't seem to
be present in archives.fedoraproject.org or in the F20 netinstall ISO.
Can anyone point me to a copy?

Apache and umask for document root
by Alex
Hi,
I've set up a virtual host for a joomla website and having some
permissions problems. I've seen numerous configurations online about
how to set umask for the apache user, but none have worked, including
creating a systemd file
(/etc/systemd/system/multi-user.target.wants/httpd.service) with the
following:
[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=notify
Environment=LANG=C
Umask=0006
ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND
ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
# Send SIGWINCH for graceful stop
KillSignal=SIGWINCH
KillMode=mixed
PrivateTmp=true
[Install]
WantedBy=multi-user.target
The problem is that the files are owned by the joomla user, but also
need to have access (both read and write) to be able to modify some
files within the document root.
Does anyone have any suggestions on how to set umask for the apache user?
I'm also interested in recommended permissions settings for the joomla
document root.
Thanks,
Alex

Audio book download -
by Bob Goodwin
.
Can anyone tell me how to download files from Amazon's audible.com with
fedora 24 that I can copy to a flash drive? They refer to several
applications they provide, none or which appear to be Linux apps ...
Normally I just get MP3 files, etc. and can deal with them.

USB flash -

"Your message to the test mailing-list was rejected for the following
reasons:

Perhaps someone can offer a suggestion here?

I am trying to use an USB flash drive but it does not mount/show up on
desktop. It is listed under lsusb though.
Normally this just works but not in this Fedora-25 beta.
What am I missing or doing wrong?

gnome-abrt claims the kernel is tainted
by George R Goffe
Hi,
"my" fc23 x86_64 system gets the following messages below which trigger gnome-abrt execution. The results of this report that the kernel is tainted but there are no modules listed. I had assumed that the tainted flag was due to the vbox kernel modules being loaded so I used rmmod to remove them. subsequently I got another message (see below) but gnome-abrt still claims that the kernel is tainted.
Am I doing something wrong or is this a bug?
Thanks,
George...

youtube-dl
by JD
A new strange behavior of this util.
When downloading a format of the file that is pure video (i.e. no audio)
I end up with tens of small files each one labeled by the name of the
listed movie
appended with .part-FragN where N ranges from 0 to more than 200
sometimes.
I updated youtube-dl by running youtube-dl -U and retried. It does the
same thing.
After it finished getting all the fragments, it does not catenate them
into a single
video file.
How can I get around this problem?
Thanx!!
