[oS-en] rsyslog filtering question.
by Carlos E. R. 24 Jan '22

24 Jan '22

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, After I upgraded to 15.3 my main machine, I see excesive verbose entries, probably debug entries, in the warning log. I want to filter them out. These are the entries I'm starting with: <3.4> 2022-01-23T22:56:02.171332+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - /etc/xdg/autostart/ibus-autostart.desktop:2: Unknown key name '_Name' in section 'Desktop Entry', ignoring. <3.4> 2022-01-23T22:56:02.171482+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - /etc/xdg/autostart/ibus-autostart.desktop:3: Unknown key name '_GenericName' in section 'Desktop Entry', ignoring. <3.4> 2022-01-23T22:56:02.171539+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - /etc/xdg/autostart/ibus-autostart.desktop:4: Unknown key name '_Comment' in section 'Desktop Entry', ignoring. <3.4> 2022-01-23T22:56:02.171911+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - Configuration file /etc/xdg/autostart/klipper.desktop is marked executable. Please remove executable permission bits. Proceeding anyway. <3.4> 2022-01-23T22:56:02.175609+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - Not generating service for XDG autostart app-xapp\x2dsn\x2dwatcher-autostart.service, error parsing Exec= line: No such file or directory So, I create this filter in /etc/rsyslog.conf: #debugging. if $syslogfacility == 3 and $syslogseverity == 4 and $programname == 'systemd-xdg-autostart-generator' \ then -/var/log/pruned.warn & stop This does work. So indeed it is facility number 3, severity 4, and the programname is correct. But I want to be more strict, and I write this modified filter: #debugging. if $syslogfacility == 3 and $syslogseverity == 4 and $programname == 'systemd-xdg-autostart-generator' \ and ($msg startswith '/etc/xdg/autostart/ibus-autostart.desktop') \ then -/var/log/pruned.warn & stop This does not trigger on the line below, it continues being written to /var/log/warn and not to /var/log/pruned.warn: <3.4> 2022-01-23T22:56:02.171539+01:00 Telcontar systemd-xdg-autostart-generator 28650 - - /etc/xdg/autostart/ibus-autostart.desktop:4: Unknown key name '_Comment' in section 'Desktop Entry', ignoring. To me, it is obvious that the message is indeed starting with '/etc/xdg/autostart/ibus-autostart.desktop', so why doesn't it work? What am I missing? If instead I write: #debugging. if $syslogfacility == 3 and $syslogseverity == 4 and $programname == 'systemd-xdg-autostart-generator' \ and ($msg contains '/etc/xdg/autostart/ibus-autostart.desktop') \ then -/var/log/pruned.warn & stop It does work. :-? - -- Cheers Carlos E.

Entering Unicode hexcodes using Ctrl-Shift-u

As reported by several list members, it appears that this no longer works in TW, and I can confirm that it also does not work out-of-box with Leap 15.3. A bit of digging around the web came up with a solution: install the package ibus and reboot. Voilà, it works again, except in a console (including eg. Konsole). By default, this will put a panel in the system tray that allows one to configure the beast to one's preferences. There are also a lot of supplementary packages that I haven't examined yet. I have no idea what any of them do, or why/when they might be needed. At least with just this one package, the basic functioning can be restored. Next silly question, why is ibus not included as part of the default configuration at install time?

Having followed your advice, I repeated deleting and re-setting up the Wifi adapter in Yast as described above, which worked now without producing an error message. Now, my problem does not persist any more, i.e. I have a wireless access to my router again - thanks a lot! Best regards, Wolfgang

[oS-en] How can I play a sound from a script?
by Carlos E. R. 23 Jan '22

23 Jan '22

Hi, I want to play a sound from a script, for example to signal it finished, but I can't. First problem: I can't find a CLI command able to play the sound files I want, found in the default installed system: er@Erebor4:~> aplay /usr/share/sounds/freedesktop/stereo/bell.oga Playing raw data '/usr/share/sounds/freedesktop/stereo/bell.oga' : Unsigned 8 bit, Rate 8000 Hz, Mono ^CAborted by signal Interrupt... cer@Erebor4:~> This command produces horrible noise with any .oga file I try. cer@Erebor4:~> madplay /usr/share/sounds/freedesktop/stereo/bell.oga MPEG Audio Decoder 0.15.2 (beta) - Copyright © 2000-2004 Robert Leslie et al. audio: No such file or directory cer@Erebor4:~> cer@Erebor4:~> paplay /usr/share/sounds/freedesktop/stereo/bell.oga cer@Erebor4:~> (silence...) cer@Erebor4:~> play /usr/share/sounds/freedesktop/stereo/bell.oga /usr/share/sounds/freedesktop/stereo/bell.oga: File Size: 8.50k Bit Rate: 487k Encoding: Vorbis Channels: 2 @ 16-bit Samplerate: 44100Hz Replaygain: off Duration: 00:00:00.14 In:100% 00:00:00.14 [00:00:00.00] Out:6.15k [ ====|==== ] Clip:0 Done. cer@Erebor4:~> (silence...) I can play sounds with VLC, but not being a CLI command, it starts a GUI that then I have to close manually. "vlc --help" is huge, I have not seen a way to play a sound and exit. I can probably convert a sound to .wav, and play that one. play, aplay, and paplay all work that way. Second problem: I can not play them as root, and I do need them as rootm because those scripts run as root.

new XPS13 9310 resume from hibernate is failing
by mh＠mike.franken.de 23 Jan '22

23 Jan '22

Hi *, yesterday I installed a new XPS13 9310 2-in-1 by preparing the necessary partitions and reovering a backup from an XPS 13 9370. Everything works ok besides resuming from hibernate. For the original XPS13 9370 this still works without any problems. When running "systemctl hibernate" on the 9310 I get systemd-sleep[5537]: INFO: running /usr/lib/systemd/system-sleep/grub2.sleep for hibernate systemd-sleep[5537]: INFO: Running prepare-grub .. systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.16.1-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.16.0-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.12-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.8-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: Skipping openSUSE Tumbleweed, with Linux 5.15.7-1- default (recovery mode), because it has the noresume option systemd-sleep[5537]: running kernel is grub menu entry openSUSE Tumbleweed (vmlinuz-5.16.1-1-default) systemd-sleep[5537]: preparing boot-loader: selecting entry openSUSE Tumbleweed, kernel /boot/5.16.1-1-default systemd-sleep[5537]: running /usr/sbin/grub2-once "openSUSE Tumbleweed" systemd-sleep[5537]: time needed for sync: 0.0 seconds, time needed for grub: 0.1 seconds. systemd-sleep[5537]: INFO: Done. systemd-sleep[5534]: Entering sleep state 'hibernate'... I get the same output from "systemctl hibernate" on the 9370. Both have a swap partition with 32 GB in size and 16 GB of RAM. Kernel command line contains resume=UUID=<uuid_of_swap_partition> in both cases. The only difference I saw is this message, that shows up on the 9310 before systemd-sleep is running: kernel: PM: Image not found (code -16) Any idea what might be wrong here? Thx and bye. Michael.

Creating a BTRFS root filesystem
by Mark Petersen 23 Jan '22

23 Jan '22

I'm trying to create a btrfs root filesystem following Richard Browns blog found here: https://rootco.de/2018-01-19-opensuse-btrfs-subvolumes/[1] but it seems that he missed a step or I can't follow directions. If I follow his recipe to the letter then no 1st snapshot is ever made and no default subvolume can be set. So, I omitted line 4 of step 4: and created a snapshot between his steps 6: & 7: btrfs subvol snapshot /mnt /mnt/(a)/.snapshots/1/snapshot After step 7: I am able to set the default subvolume, but I have the @ subvolume showing when I list the directory in step 8: Anyone have some pointers? Thanks. Mark -------- [1] https://rootco.de/2018-01-19-opensuse-btrfs-subvolumes/

How to connect via WiFi
by Wolfgang Mueller 22 Jan '22

22 Jan '22

My new computer is an HP 15s-eq2147 FHD RYZ5-5 16GB 512 SSD DOS It has no cable connection to the internet, but only access via WiFi. Installing Leap 15.3 was no problem, but so far I did not manage to establish a WiFi connection. Using Yast, I set up a wicked service with fixed address, getting this list: Device Name: wlan0 Configured with address 192.168.2.16/24 (acer.ariannuccia.zz) Starting automatically on cable connection I find it somewhat absurd that a cable connection is required even for WiFi. Since I have no cable connection, I am looking for a work around. Any idea? The "Authentication Mode" offers these 5 options: No Encryption WEP - Open WEP - Shared Key WPA-EAP ("enterprise") WPA-PSK ("home") On my router (192.168.2.1) there are these "Encryption type": Unencrypted (not recommended) WPA2 (very secure) WPA / WPA2 (secure) WPA (secure) For avoiding problems with the correspondence of these methods, I have selected "No Encryption" on my computer and "Unencrypted (not recommended)" on my router. But the connection does not work. Any attempt to ping the router from the new computer is rejected with the reply: connect: Network is unreachable Any help would be welcome. Thank you in advance and best regards, Wolfgang

authentification system
by jdd＠dodin.org 22 Jan '22

22 Jan '22

Hello, I'm building an usenet server on top of Leap 15.3. Looks like it would be interesting to authenticate users. Somebody spoke of kerberos. I don't expect more than a hundred users, at most. do you know some system a bit simpler? Do you have some link (including to Kerberos under Leap)? thanks jdd -- http://dodin.org http://valeriedodin.com

Compose key.
by Carlos E. R. 21 Jan '22

21 Jan '22

Hi, On this same machine, on 15.2 I have edited file "/etc/X11/Xmodmap". !! Fourth example: Make Menu key on WIN95 keyboard doing Compose !! CER !! keysym Menu = Multi_key !! keysym Win_R = Multi_key Does not work !!keysym Win_Menu = Multi_key Neither keysym Super_R = Multi_key This activates the compose key (using XFCE), on the right "Windows" key of my keyboard. On Leap 15.3 the exact same paragraph does nothing. Fresh test install. Why? -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.3 x86_64 (Erebor-4))
