Killing only selected Chrome windows from the CLI ?
by Philip Rhoades 28 Mar '18

28 Mar '18

People, This command exits the chrome process tree gracefully, in all window managers: pkill --oldest chrome but it is not what I want to do - when Chrome goes mad and the whole system starts grinding to a halt (I know from experience it is Chrome) I want to try and work out what specific Chrome tab or window is the problem. Chrome has its own task manager: SHIFT ESC but you can't kill a window with all its tabs from there. Using: ps aux | grep "beta\/chrome" seems to indicate individual tabs? Using: xprop _NET_WM_PID and clicking on the different windows always give the same id. I wrote the script below using wmctrl and xkill to allow me to kill the Chrome windows in reverse order of creation but killing the first Chrome window kills all Chrome windows. The xkill man page says the "program is very dangerous" and: -id resource This option specifies the X identifier for the resource whose creator is to be aborted. - so it looks like aborting "creator" gets rid of everything. Any suggestions about fixing my script to selectively kill single Chrome windows? Thanks, Phil. #!/bin/bash wins=`wmctrl -l | sort -r` IFS=$'\n' # bash 4 readarray -t winsarr <<< "$wins" for win in "${winsarr[@]}" do IFS=' ' read id junk1 junk2 name <<< $win echo "$id $name" echo -n "Kill?: " read junk if [ "$junk" == "Y" ]; then xkill -frame -id "$id" fi done -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

F27 boots to grub> after (failed?) dnf update ?
by linux guy 28 Mar '18

28 Mar '18

I ran DNF update via ssh on my x86_64 FC27 server the other day. For some reason it didn't finish and when I rebooted it, it boots to a grub prompt. "Minimal BASH-like line editing..." grub> So... grub> set root=(lvm/fedora/root) grub> linuxefi (hd0,gpt2)/linuz-4.14.13-300.fc27.x86_64 grub>initrdefi (hd0,gpt2)/initramfs-4.14.13-300.fc27.x86_64.img grub>boot This gives me a switch root error and stops at the emergency mode prompt #. How do I get my server to boot again ? Thanks

multiple GUI logins and mounting external drives
by Tim 27 Mar '18

27 Mar '18

Hi, If I use the GUI switch user feature, so that two users are currently logged into the same PC, graphically (and you can switch between them using CTRL+ALT+F1 and CTRL+ALT+F2), I frequently find that whenever I plug in a USB drive, or SD card, that nothing pops up on the login that I'm using. It nearly always pops an authentication window on the other login. It doesn't matter which one I'm currently using, it nearly always uses the other one. Surely the system knows which one is currently on- display, and should use that one? -- [tim@localhost ~]$ uname -rsvp Linux 4.15.10-200.fc26.x86_64 #1 SMP Thu Mar 15 17:14:41 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted. There is no point trying to privately email me, I only get to see the messages posted to the mailing list. George Orwell's '1984' was supposed to be a warning against tyranny, not a set of instructions for supposedly democratic governments.

"Malformed URL" popup when trying to mount an external drive (KDE)
by PropAAS DBA 27 Mar '18

27 Mar '18

All; I'm running Fedora 27 KDE spin, fully updated. Every time I plug in an external drive, no matter what file system is on the drive (i.e. a windows usb stick, an ext4 external ssd drive, etc) and click "Open With File Manager" I get a popup that simply says "Malformed URL" with the only option / button of "OK". The drive does mount, but the error is annoying. Thoughts? Thanks in advance

OT: little help for fixing a spreadsheet template
by Antonio Olivares 27 Mar '18

27 Mar '18

Dear kind folks, I asked for a little bit of help regarding a spreadsheet sports template. We have a different system than the regular 3 points for a win, 1 point for a draw and 0 points for a loss. In our system we have 3 points for a win(in regulation), 2 points for a win(in OT/PKS-penalty kick shootout), 1 point for a loss(in OT/PKS), and 0 for a loss in regulation. There is a website that has some nice templates to use and all we need is to cut the competition to two rounds only as we play round-robin and we need to modify the existing templates to figure this out for us. http://excel-example.com/templates/sport-tournament-template In the comments section, the question has been asked in the comments section but no replies to that question. Usually the scores are entered as Use 1- first half 2- second half OT1 overtime 1st period, OT2- 2nd Overtime period and PKS-penalty-kicks Team1 1-0 2-0 OT1-0 OT2-0 PKS-3 Team2 1-0 2-0 OT1-0 OT2-0 PKS-2 so Team1 wins 1 to 0 in PKS there are 0 goals added to the GF and 0 goals added to GA and earns 2 points Team2 looses 1 to 0 in PKS and gets 0 goals in favor and 0 goals against and earns 1 point This should happen for all the games to be played. We were in a 6 team district and now we will be moved to an 8 team district. We can open the spreadsheet with LibreOffice and keep using xlsx and/or convert it to ods. Thanks for any help/advice/suggestions. Best Regards, Antonio

The IPA Server hostname must not resolve to localhost (127.0.0.1). A routable IP address must be used.
by Peter Bittner 27 Mar '18

27 Mar '18

Hi there, I'm trying to set up an all-in-one infrastructure system (using Vagrant), which included FreeIPA, libvirt and The Foreman, and some other software. The Idea is that I (locally) bootstrap such a system that helps users to create their definite infrastructure management setup in the end. Naturally, this entails that FreeIPA is installed on localhost. This, however, doesn't seem to work: The `ipa-server-install` script aborts and issues the following error message: The IPA Server hostname must not resolve to localhost (127.0.0.1). A routable IP address must be used. [...] Is there any way to make a local install happen? Or what do I have to do instead? Any thoughts and ideas highly appreciated, Peter

shutdown messages
by François Patte 25 Mar '18

25 Mar '18

Bonjour, While shutdowning, I can see, but have not the time to read, some strange messages on the console. These messages are not logged. Is there a way to slow down the message display at shutdown. A good tool would be an "interactive" shutdown: press a key to access the next displayed page of messages. Thank you. -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte

new selinux question
by François Patte 25 Mar '18

25 Mar '18

Bonjour, Today I wanted to activate the dictd service on my computer. This failed and I received a selinux alert: mdadm wanted to access something... No connection with dictd. After a few researches, I was sure that selinux was blocking the dictd start. But the selinux troobleshooter only refers only to the first 40 alerts and I had to go to the audit logs to find out what was the problem with the dictd service. Why is se-troobleshooter is so limited? Thank you -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)6 7892 5822 http://www.math-info.univ-paris5.fr/~patte

Adding an application to Fedora
by Robin Laing 25 Mar '18

25 Mar '18

Hello, There is some discussion on a different list about adding an application to Fedora. I looked at the web site https://developer.fedoraproject.org/start.html and is this all that someone starts from? How about taking over a project that seems abandoned? Thanks in advance. Robin
