nc missing option -z
by Suvayu Ali 03 Nov '16

03 Nov '16

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. -- Suvayu Open source is the future.

Alternatives to Theme Font size changer Firefox plugin?
by Sam Varshavchik 28 Oct '16

28 Oct '16

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?

F21: Thunderbird insists on calling Fedora list messages junk!
by William Mattison 13 Jul '16

13 Jul '16

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.

how to set 24-hour clock (military time) on Fedora 20 in KDE?
by Kenneth Wolcott 04 Jul '16

04 Jul '16

Hi; I can't seem to find any way to change the Fedora 20 KDE time and date settings so that the time is displayed in the 24-hour format like military time. Is this not possible? Thanks, Ken Wolcott

installing via VNC over ipv6
by Chris Murphy 29 Jun '16

29 Jun '16

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. -- Chris Murphy

smplayer volume control
by Andre Robatino 09 Apr '16

09 Apr '16

For a long time now, the smplayer (from RPMFusion) volume control is vertical, instead of horizontal, with a negligible height, so it's essentially useless. This is still true with the latest version smplayer-16.1.0-1.fc23, and even after deleting ~/.config/smplayer. Do all Fedora users see this, and can it be fixed?

Major owncloud updates incoming
by James Hogarth 02 Apr '16

02 Apr '16

Hi all, We're at the last stages of preparing the first major owncloud update in a while. The current version of owncloud in Fedora is the fairly old stable 8.0 release (presently 8.0.10) which we want to bring back in line with the current owncloud upstream release of 8.2.2. Unfortunately it's not possible to migrate directly from 8.0.x to 8.2.x as upstream only supports jumping in increments with no skipping of major releases. In order for a smooth transition to 8.2.x (and after that 9.0.x when it's released) we'll be releasing 8.1.5 to F23 and F22 within the next couple of weeks. We plan to leave this in updates-testing for a slightly longer period than usual to allow for a wider test base for a major version jump. Please remember your backups prior to the upgrade! Once 8.1.5 is pushed to updates 8.2.2 will be pushed to updates-testing for a similar extended period. It's imperative that the 8.1.5 update is applied before the 8.2.2 update is pushed to updates. If you want to assist in the testing and provide feedback or bug reports please use the usual channels of bodhi and bugzilla - both easily accessible from pkgdb: https://admin.fedoraproject.org/pkgdb/package/rpms/owncloud/ Kind regards, James

Protecting my network from rogue IoT devices.
by Javier Perez 02 Mar '16

02 Mar '16

Probably Off Topic, but maybe tangentially related to Fedora. I read with interest this forum piece about IoT devices phoning home. https://isc.sans.edu/forums/diary/IoT+The+Rise+of+the+Machines+Guest+Diary/… What caught my attention is the following phrase: " My home network is hardened and any new (unknown) device connected to it receives an IP address from a specific range which has no connectivity with other hosts or the Internet but its packets are logged" I imagine it is done through the Gateway Router at home. Is there any tutorial somewhere to learn how to do this? Also, what program could one use on FedoraServer or FedoraWorkstation to host the log created by the router ( I imagine some sort of dd-wrt machine). Given that journalctl took over syslog duties, could I still use syslogd to receive the data from an external router or do I have to look somewhere else for that? I wonder. -- ------------------------------ /\_/\ |O O| pepebuho(a)gmail.com ~~~~ Javier Perez ~~~~ While the night runs ~~~~ toward the day... m m Pepebuho watches from his high perch.

Openvpn Configuration/Access Issue
by Stephen Morris 01 Mar '16

01 Mar '16

Hi, I am trying to my vpn service provider using instructions they provide for Ubuntu Mint as the only information they provide for Linux. When I go into Networkmanager and create a new Openvpn connection and try to connect to it, I get a popup saying the connection failed and one of the messages seems to be indicating that I am missing a plugin. As far as I can see I have every Networkmanager vpn plugin installed, so I am at a loss trying to understand the message. Is anybody able to shed any light on what/where I need to look to try to identify what the connection issues are? regards, Steve

OT: recommended way of timing two pieces of code in C
by Ranjan Maitra 29 Feb '16

29 Feb '16

Hi, Disclaimer: This is clearly marked OT, with the only connection to this group being the fact that I am running F23 on a 20-core Dell T5810 @3.1 GHz each and 64 GiB memory. My OT queries over the past 13 years (almost) here have elicited great wealth of information so I am posing here. So, I am trying to compare two kinds of methods in a C program. Both are written as efficiently as possible (assumed because no point otherwise). I would like to know which of these is more efficient. I have been using get_rusage but I was wondering whether there is a better way? Separately, is there a way to get the number of floating point instructions in C? Both FLOPS and MIPS?
