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.

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

I modified it to above and removed ExtData1 reference and it worked. I tried to set the xtics manually and change them according to Marco's reference, but the graph did not refect all the games so I modified the data file and added the date and the opponent and then modified the range to prohibit the line going below and keep everything in quadrant I. If anyone has a nicer way to make the graph look better, or format it using something else please help. I would like for our athletes to see what we need to work on the Goal Differential and not allow too many goals against us.

Issues with install F23 MATE desktop
by Chris Adams 19 Jan '16

19 Jan '16

I have a brand-new Dell Precision workstation, on which I'm trying to install Fedora 23 (with my preferred desktop environment, MATE), which is turning into the most frustrating Linux install I've experienced in a long time (and I've been using Linux since before Red Hat existed). I started with Fedora-Workstation-netinst-x86_64-23 on a thumb drive. I booted, selected automatic partitioning and MATE, and it started downloading RPMs. When it finished downloading, it rebooted. Apparently, there's a conflict between release and updates on who owns /etc/xdg/menus/mate-preferences-categoris.menu, and anaconda just crashes and reboots (not even a traceback) on an install transaction failure. After a few passes through that before I figured out anaconda was not going to install MATE (with frustrating waits for downloads each time), I gave up and did a minimal install. Then I did a dnf groupinstall MATE, and that downloaded all the RPMs, then gave me the error about the file conflict. I tried to exclude one of the choices, use --best, etc., and nothing would solve it. Also, when "dnf groupinstall foo" is run, even if it fails, dnf then thinks the group is installed (and so a repeated groupinstall does nothing). I had to do a groupremove first. I just manually installed the RPMs from the dnf cache to get around the MATE brokenness, and then got systemd to do a graphical boot. Now, when I get to the graphical login, my USB is dead. I can boot single-user mode and the keyboard works fine; as soon as the graphical login loads, USB appears dead (keyabord is like it is powered off, no Numlock, Capslock, etc.). Tried unplugging keyboard, moving it to different USB ports (directly on the computer instead of hub), etc. with no result. The fact that the keyboard works in single-user mode shows there's no hardware problem, Linux USB issue, etc. At this point, I guess I'll roll back and try Fedora 22. If I ever get a working desktop, I'll try to file some bugs I guess. I found a BZ about anaconda that appears to match my problem (1287841). That doesn't explain the MATE conflicts in the repos, dnf groupinstall fail, or disappearing USB though. -- Chris Adams <linux(a)cmadams.net>

XFCE power manager no longer turns off the monitor
by Sam Varshavchik 09 Jan '16

09 Jan '16

At some point recently, my monitor stopped getting turned off after the prescribed period of inactivity. I'm using the XFCE power manager, and its settings remain untouched. Manually executing "xset dpms force off" turns the monitor off normally. "xset q" shows that everything appears to be in order: DPMS (Energy Star): Standby: 300 Suspend: 360 Off: 420 DPMS is Enabled Monitor is On So, what else can I check?

Looking for a printer
by thomas cameron 08 Jan '16

08 Jan '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Howdy, all - I have an Epson Workforce 600 printer, and it's actually a great printer except for one thing: it goes through ink cartridges like an out of control tweaker in a room full of meth. I need a printer with the following features, and I'd love any advice/experience you have had: 1) networked, works with Linux (the kids and me) and Windows (wife) 2) color 3) fast print speed (not as high a priority, but nice) 4) prefer laser printer, as opposed laser jet I had an HP LaserJet 4, and it was awesome, but it was not color and it finally died. I'm looking for that sort of experience, just newer. Any suggestions?

How to change id and group to the user
by Walter Cazzola 07 Jan '16

07 Jan '16

Dear Experts, as you probably know (from another thread) I've just installed Fedora 23 on my dell m6800 and I have a new problem. I have let the installer create my user and it has given it uid 1000 and gid 1000. This is the standard behavior and I'm used to change it by manually edit /etc/group and /etc/passwd but this time this behavior has broken my user. I can't enter at the kde login (before in the splash screen it was asking for the password of my user than asking for a password but no user was specified and I got a login erro when I use my passowrd). Also removing the user with userdel and readd it with useradd didn't solve the issue. The only fix I found was to reinstall the whole system. But now I still have the need to change the user uid and its group number. Which is the correct way? Thank you again for the help and Merry Christmas Walter --

Scroll Bars not Working Properly in F22 Applications in KDE
by Stephen Morris 05 Jan '16

05 Jan '16

I have an issue certain applications not displaying the scroll bars properly. I am using the upstream Nightly version of Firefox and the upstream Daily version of Thunderbird. Both of these display the vertical scroll bar permanently, but neither of them display the top and bottom arrows. Another application I have looked at is Gedit which only displays the vertical scroll bar when you mouse over it, but it doesn't display the top and bottom arrows either. I get these issues irrespective of what KDE theme I use. Looking at the KDE Settings App it displays the scroll bars with top and bottom arrows fine. The Kwin script to force window decorations on GTK+ apps is active. Does anyone have any ideas why the above mentioned applications don't show the arrows but the KDE Settings Application does show the arrows, and whether or not there is anyway to rectify it? From memory I did not have this issue in F21 and F22 was installed from scratch from the live DVD because the F21->F22 upgrade process does not work on my system (the upgrade process wants to run the install from the Grub menu and on my system my wireless network is not active at that point and cannot be made active because of required drivers). regards, Steve
