How to remove duplicates (all but installed ver) from /var/cache/zypp/packages ?
by David C. Rankin 13 Mar '23

13 Mar '23

All, We have touched on this before, years ago, 10/11.x days, but the opensuse package name format and variations have changed a bit. What I want to do is find /var/cache/zypp/packages -type f -name "*rpm" | sort --version-sort all the rpm files in /var/cache/zypp/package and remove all duplicates leaving the currently installed rpm version in /var/cache using awk to split path/rpmname and then outputting the record while last == current to pipe to xargs rm -f (which seems to work fine and I'm not worrying about rpm names containing the '\n' character which would necessitate creating and processing records with a nul-character at the end, e.g. -print0 and xargs -0) How to best do that? So long as find ... | sort --verison-sort will give the rpms in version sort order, piping to a short awk script and then to xargs will do. I did this on a few zypp/package dirs by hand, but now I want to automate processing the entire cache for those repos that have --keep-packages set. But before I spend an hour or so testing and tweaking is the a standard way to discard all but installed from /var/cache -- that would keep me from reinventing the wheel? (I have additional repos like devel-gcc, etc.. so package names can have +gitxxx as a version number suffix -- if that makes a difference) -- David C. Rankin, J.D.,P.E.

Plantronics USB headset and mute button
by mh＠mike.franken.de 10 Mar '23

10 Mar '23

Hi *, I use a Plantronics USB headset, which has volume buttons (level up/down, mute). Pressing the mute button, the headset says "open mic on"/"open mic off". As for applications like Citrix workspace app or Microsoft Teams the mute state was synched, so that the app also shows a mic symbol, that was crossed out or not. If such an app was connected, the red led at the USB plug also showed the state of the mute button; if it was red, the headset's micro was muted. I could either press the headset's mute button or the virtual mute button in the app with the same result. Starting today, this sync stopped working. As for the GUI itself everything works as usual - "open mic on"/"open mic off" and level up and down. But the apps don't get the mute state any longer. To really mute or unmute the mic I have to klick the virtual button in the app, pressing the physical mute button of the headset has no effect. Also the red led does not show the mute state any longer. The only change from yesterday was the installation of the latest Tumbleweed snapshot 20230307, but as for the history it contains no package that could have such an effect - at least not obvious for me. I tried switching between pulseaudio and pipewire to no avail. Any idea, what might have caused this and what to do to get the desired state back? TIA. Bye. Michael.

ssh and named/bind
by Marc Chamberlin 09 Mar '23

09 Mar '23

Hello - I am running an OpenSuSE 15.3 x64 system where I am also running a NAMED server for my network. > quasar:/etc/named.d # named -v > BIND 9.16.6 (Stable Release) <id:25846cf> > quasar:/etc/named.d # ssh -V > OpenSSH_8.4p1, OpenSSL 1.1.1d 10 Sep 2019 Apparently recently something has changed which is now breaking SSH's ability to connect to a URL with upper case letters in the host name. (I connect and use SSH within a port knocking script which has worked for many years, so I know it is not caused by something I am doing, but by a change that has occurred within either SSH or NAMED.) Internet and Googling searches seem to imply that Bind (NAMED) is now resolving URL's in a case sensitive fashion. https://kb.isc.org/docs/aa-01113 and I suspect this change has just now caught up with me. But, I don't know if the fault lies entirely with Bind/NAMED. SSH appears to be mangling URLs, changing upper case letters within a URL, to lower case before asking a name server to resolve them. (IMHO this is extremely bad behavior on SSH's part because it is destroying user supplied data, something a program should never do!) Here is an example of what I am seeing that leads me to this conclusion - > ssh marc(a)darkstarINT.mydomain.com > ssh: connect to host darkstarint.mydomain.com port 22: No route to host Notice SSH changed the upper case "INT" in the host name "darkstarINT" to a lower case "int" in the query. I checked the log file at /var/log/named/named and indeed saw the query for the URL, from SSH, was all lower case. The message "No route to host" is misleading (probably because of bad error handling) and just means SSH was unable to get an IP address from the DNS server for the URL host name, that it mangled. Doing some further Googling, I found some references to using an ACL declaration in the NAMED configuration files, but I am unable to find any easy/clear guidance or examples on how to do this. Does anyone here know either how to keep SSH from converting a URL, that it is querying, to stop this horrid conversion of a URL to all lower case, or how to get NAMED to handle queries in a case insensitive manner? (perhaps using the ACL declaration that I found some references to.) If not, does anyone know of a better forum I could ask? Links to documentation, with examples, would also be appreciated, after hours of searching I was not able to find anything helpful. I know I could go through all my NAMED configuration files and and either add duplicate zones or use CNAME perhaps to add in all lower case equivalent host names but that seems like a huge burden and a bunch of extra maintenance overhead.

Enlarging BTFS filesystem on Tumbleweed.
by Frank McCormick 08 Mar '23

08 Mar '23

I want to enlarge the file system on my Tumbleweed partition and even after Googling the situation, I feel the whole procedure is definitely above my pay grade :) I have a 500 gig main drive split into various partitions. Disk /dev/sda: 447.13 GiB, 480103981056 bytes, 937703088 sectors Disk model: KINGSTON SA400S3 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xf73048ad Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 489330687 489328640 233.3G 83 Linux /dev/sda3 489334782 937699691 448364910 213.8G 5 Extended /dev/sda5 489334784 712566783 223232000 106.4G 83 Linux /dev/sda6 712568832 933502975 220934144 105.3G 83 Linux /dev/sda7 933505024 937699691 4194668 2G 82 Linux swap / Solaris Tumbleweed is on sda6, Debian Sid on sda1 using ext4, Fedora is on sda5 also with ext4 with swap space on sda7. I would like to delete Fedora from sda5 and enlarge sda6 to include that space . I'm planning KVM in Tumbleweed with a version of Fedora. What is the best way to go about this? I know partition work can only be done with the disk not mounted so it appears I'd have to boot from an external utility. If possible I'd like suggestions on the best way to proceed. From what I've read a BTRFS file system can only be enlarged from the front and not from the rear? All help appreciated. Thanks

Hi, I'd like to have a few extras variables in a sudo session for a special user or group. I created a new file "mygroup" in /etc/sudoers.d/ with these contents: Defaults exempt_group = mygroup Defaults:%mygroup env_keep="PERL5LIB DISPLAY XAUTHORITY" Is this the correct way to do this? Thx! Bye. Michael.

How to configure Postfix when relayhost only offers GSSAPI and NTLM
by Freek de Kruijf 06 Mar '23

06 Mar '23

My new provider offers on port 587 "250-AUTH GSSAPI NTLM" I am trying to configure my postfix using as relayhost this smtp server. Using kmail I am able to simply provide the username, an email address, and a password. However I have a script that has to send an email. I use mailx to do that, which sends the message to postfix and postfix should send it to the server of my provider. My previous provider offered LOGIN an PLAIN, for which it apparently was easy to configure Postfix. I configured both NTLM and GSSAPI as mechanisms in Postfix. In /etc/postfix/ sasl_passwd the username and password are configured. Error messages in /var/log/mail: postfix/smtp[14307]: warning: SASL authentication failure: GSSAPI Error: No credentials were supplied, or the credentials were unavailable or inaccessible (No Kerberos credentials available (default cache: KEYRING:persistent:51)) postfix/smtp[14307]: 92C8D101152: to=<xxxxx(a)yyyyy.nl>, relay=smtp.yyyyy.nl[212.113.64.zz]:587, delay=16453, delays=16453/0.02/0.14/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server smtp.delta.nl[212.113.64.82]: generic failure) -- fr.gr. member openSUSE Freek de Kruijf
