How do I set the run target and turn off services on a non running installation ?
by linux guy 09 Mar '17

09 Mar '17

I have a non booting installation that I need to get running. I would like to know how to change the run target to the command line and disable several services that are causing issues during the boot process. How does one manually change the run target on a non booting installation ? What do I edit ? Because my installation doesn't boot, I can't run systemctl, so I must edit the link manually. How does one manually disable services so they don't start during the boot process ? Because my installation doesn't boot, I can't run systemctl, so I must edit the configuration manually. Thanks

Good firewalld documentation?
by Chris Adams 09 Mar '17

09 Mar '17

I'm trying to switch from using straight iptables to firewalld, but I'm not really "getting it" with how firewalld works. The documentation on firewalld.org doesn't really explain things to me. On a server, I would typically restrict management access (SSH, SNMP) to certain subnets, and leave the other ports (HTTP, HTTPS) open with an iptables like below. What would be the easiest way to accomplish the same thing with firewalld? ************************************************************************ :INPUT ACCEPT [0:0] :FORWARD DROP [0:0] :OUTPUT ACCEPT [0:0] :mgmt - [0:0] -A INPUT -i lo -j ACCEPT -A INPUT -p tcp --dport 22 -j mgmt -A INPUT -p udp --dport 161 -j mgmt -A mgmt -s xx.xx.xx.xx/xx -J ACCEPT -A mgmt -s yy.yy.yy.yy/yy -J ACCEPT -A mgmt -p tcp -j REJECT --reject-with tcp-reset -A mgmt -j DROP COMMIT ************************************************************************ -- Chris Adams <linux(a)cmadams.net>

How to add words to system spell-checking dictionary
by Andrew Toskin 09 Mar '17

09 Mar '17

Repost of my question on Ask Fedora -- https://ask.fedoraproject.org/en/question/101943/how-to-add-words-to-system… I'm trying to figure out how to add words to a spelling dictionary so that I get the most impact for the effort --- some way to have it apply to all applications, *or at least as many of the ones I actually use* as possible. If I have to target specific spell checkers for specific applications, then I'm mostly interested in adding words to the spell checking dictionaries used by the applications I most often compose text with: Firefox for web forms, Evolution for email, Atom and gedit for code and plain text, and LibreOffice for office documents. Each of these applications has a way to add words to their own spelling dictionary, but those dictionaries are application-specific, and I would have to add a given word to all of them. So I've been hunting to see If they share a single spell-check system, or even if there's 2 or 3 systems that covers all of those. Here's what I've found out so far: I notice my system in particular has these packages which match "spell" in the name, plus enchant: * aspell - 12:0.60.6.1-14.fc25 * gnome-python2-gtkspell - 2.25.3-48.fc25 * gspell - 1.2.3-1.fc25 * gtkspell - 2.0.16-11.fc24 * gtkspell3 - 3.0.9-1.fc25 * hunspell - 1.4.1-1.fc25 * hunspell-en - 0.20140811.1-5.fc24 * hunspell-en-GB - 0.20140811.1-5.fc24 * hunspell-en-US - 0.20140811.1-5.fc24 * enchant - 1:1.6.0-14.fc25 * python3-enchant - 1.6.8-1.fc25 Wikipedia says hunspell replaces myspell and is widely used. `rpm --query --requires` says that Firefox and LibreOffice both depend on hunspell. gedit uses gspell, which relies on enchant, which can use myspell as a backend --- and the directory `/usr/share/myspell/` is actually owned by hunspell. Atom's spell-checking package searches in the myspell directory too, so it seems like I *should* have a good chance of doing everything I want to do from the hunspell configuration. So I tried creating a user addon dictionary by creating the file `~/.hunspell_en_US` containing a few line-separated words (all lower case except for proper nouns, no /flags or anything). However, those words are still marked as a spelling error in all the applications I'm testing on, *except* for hunspell itself, via the command line tool. Why isn't it working?

Mount of NAS Ethernet Connect to Router Fails at Boot Time for CIFS Interface in F24
by Stephen Morris 06 Mar '17

06 Mar '17

Hi, My Nas device now fails to mount at boot time via the CIFS definition in fstab but the corresponding NFS definition mounts quite happily. Also after the system comes up and I log into KDE I can manually mount the CIFS device. As far as I am aware the only difference between when it was mounting at boot time and now is several system updates, also the system update I did yesterday morning (which updated several hundred packages, which included a new kernel) has not rectified the issue. The systemctl output is below, I have blanked out the userid and password for security reasons. Does anyone have any ideas why this has now stopped working? systemctl status mnt-nas.mount ● mnt-nas.mount - /mnt/nas Loaded: loaded (/etc/fstab; bad; vendor preset: disabled) Active: failed (Result: exit-code) since Tue 2017-01-17 06:40:15 AEDT; 40min ago Where: /mnt/nas What: //192.168.1.12/Volume_1 Docs: man:fstab(5) man:systemd-fstab-generator(8) Process: 1299 ExecMount=/usr/bin/mount //192.168.1.12/Volume_1 /mnt/nas -t cifs -o username=********,password=********,cache=strict,_netdev,rw (code=exited, status=32) Jan 17 06:40:15 localhost.localdomain systemd[1]: Mounting /mnt/nas...

running some X11-Applications with sudo under GNOME/Wayland fails
by Joachim Backes 06 Mar '17

06 Mar '17

Hi, seeing coincidentally that some X11 applications with sudo under GNOME/Wayland will fail: ------------------------------------------------------------- For example: 1. sudo xterm No protocol specified Warning: This program is an suid-root program or is being run by the root user. The full text of the error or warning message cannot be safely formatted in this environment. You may get a more descriptive message by running the program as a non-root user or by removing the suid bit on the executable. xterm: Xt error: Can't open display: %s 2. sudo gnome-terminal No protocol specified Unable to init server: Could not connect: Connection refused Failed to parse arguments: Cannot open display: ---------------------------------------------------------------- Running the same under Gnome/Xorg executes properly. Anybody sees this too? Kind regards Joachim Backes -- Fedora release 25 (Twenty Five) Kernel-4.9.13-200.fc25.x86_64 Joachim Backes <joachim.backes(a)rhrk.uni-kl.de> https://www-user.rhrk.uni-kl.de/~backes/

Restarting systemd
by Patrick O'Callaghan 06 Mar '17

06 Mar '17

'dnf update' (using the tracer plugin) often tells me to restart certain services via systemctl, which is fine. However on occasion it tells me to restart something manually. I can usually figure out how to do this, but the one I can't figure out is systemd itself: ... You should restart: * These applications manually: systemd # systemctl daemon-reexec # tracer You should restart: * These applications manually: systemd Sending HUP, TERM etc. to systemd doesn't make any difference. Is there a way to do this without rebooting? For extra credit, why is the output of tracer different when running via sudo or su within a GUI, compared with running directly as root logged into a text console? The above commands were run using the latter. When using the former, tracer gave no output. poc

Setting default Xsession on Fedora 25
by Laverne Schrock 05 Mar '17

05 Mar '17

Hi, I'm using GDM on Fedora 25 and want to change the default graphical session that is used. The "built in" default session is the "Gnome" session, but I want the default session to be the "Gnome Xorg" session. I have added DefaultSession=gnome-xorg.desktop and WaylandEnable=false to the [daemon] section of /etc/gdm/custom.conf as recommend here: https://ask.fedoraproject.org/en/question/96134/how-can-i-set-xorg-as-a-def… I have also deleted all the contents of /var/lib/AccountsService/users so that no per-user defaults cause problems. Here is what happens. I boot up the computer, type in my username, hit enter, and type in my password. Before I proceed, I check which session is going to be used. "Gnome" is the one selected on the list. I proceed anyway. After login, I see that Xorg is running, NOT Xwayland. I log out, and the go to log back in. I check the list again, and "Gnome" is still selected. This time when I log in, Xwayland is running. Huh? If I manually select the "Gnome Xorg" entry, I get what I expect and my preference will be saved, but I want to set the default for all users. Am I doing something wrong or does this seem like a bug? If it is a bug, I don't know which package it actually belongs to. Thanks, Laverne Schrock P.S. My graphics card: $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
