nc missing option -z
by Suvayu Ali 02 Nov '16

02 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.

31 Oct '16

I know its not been updated in years, but this is still a must have for me. I just upgraded to fedora 24 (64bit) and Im trying to compile it from source because the rpms Ive found are either broke or dont work right.

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?

Taskbar Panel in Plasma Won't Autohide
by Stephen Morris 10 Oct '16

10 Oct '16

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 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.

Chrome blocks hibernation

This is weird. A few days ago I found that my desktop system (F23 fully updated) would no longer hibernate. A glance at "journal -xe" showed a bunch of lines like: Jun 14 00:50:51 bree audit[12591]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12591 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:50:51 bree kernel: audit: type=1326 audit(1465861851.266:7800): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12591 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:50:59 bree audit[12599]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12599 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:50:59 bree kernel: audit: type=1326 audit(1465861859.424:7801): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12599 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:51:07 bree audit[12603]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12603 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:51:07 bree kernel: audit: type=1326 audit(1465861867.128:7802): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12603 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:51:20 bree audit[12608]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12608 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:51:20 bree kernel: audit: type=1326 audit(1465861880.130:7803): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12608 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:52:09 bree audit[12646]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12646 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:52:09 bree kernel: audit: type=1326 audit(1465861929.397:7804): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12646 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:52:25 bree audit[12662]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12662 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:52:25 bree kernel: audit: type=1326 audit(1465861945.701:7805): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12662 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 Jun 14 00:52:25 bree audit[12667]: SECCOMP auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12667 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c000003e syscall=273 compat=0 ip=0 Jun 14 00:52:25 bree kernel: audit: type=1326 audit(1465861945.768:7806): auid=1000 uid=1000 gid=1000 ses=1 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=12667 comm="chrome" exe="/opt/google/chrome/chrome" sig=0 arch=c00 and when I killed Chrome then hibernation worked again. So one question is: what is the magic incantation to stop these alarms from Chrome? However another question is how is this even possible? A process with normal user privileges can prevent the system from hibernating? Is this right? poc

enp0s8 not configured notification popups every few minutes (annoying)
by Kenneth Wolcott 05 Jul '16

05 Jul '16

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

NetworkManager drops config on link down
by Chris Adams 05 Jul '16

05 Jul '16

I have a USB ethernet adapter on my desktop system that I use when configuring new equipment (servers, routers, switches, etc.). I have a variety of pre-set configs in NM, like 192.168.0.x, 10.0.0.x, etc. Often while configuring something, I need to reboot it, which drops the link. NM "helpfully" de-configures the interface, and I have to wait for link to return and re-select the right config (because NM won't let me select a config for an interface that is link-down). Is there a way to disable this "helpfulness", so that for this USB ethernet interface, once I select a config, it stays configured (even if the link drops)? This is frustrating behavior in many cases. -- Chris Adams <linux(a)cmadams.net>

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
