[oS-en] Suddenly, mouse wheel doesn't work.

25 Apr '23

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Suddenly, mouse wheel doesn't work. It was working, and suddenly it stopped working. I was seeing strange messages in log related to usb, so I unplugged/replugged the mouse, no effect. I downgraded the kernel several versions, no effect. Middle button, which shares the wheel, works. Leap 15.4. XFCE. What can I do to diagnose? This one is a trackball. I connected at the same time a second mouse, cheapo, and it works fine.

Leap 15.4 mailx quite dated
by David C. Rankin 15 Mar '23

15 Mar '23

Devs, mailx is a fantastic command line mailer, but the version for 15.4 is more than a DECADE out of date, e.g. $ mailx -V 12.5 7/5/10 Uhhh, that's July 2010 folks? Why are we not using the s-nail package which still enjoys active development? E.g. $ mailx -V mail v14.9.24, 2022-03-26 (built for Linux) At least that's only 11 months old, not 13 years... -- David C. Rankin, J.D.,P.E.

Finding recent work directories
by Robert Webb 04 Mar '23

04 Mar '23

Since I often get side-tracked and forget what I was doing, I wrote a script to find directories with recent (or otherwise selected) files in them. That makes a better list than sorting directories by their own modification times. This script, 'finddirs_by_latest_file', allows to restrict the search with extra find expression terms, but I usually just run the second script below, 'fblf100', which invokes finddirs_by_latest_file to make two lists; for the latest 5 and 100 days (or whatever time periods given). Excuse all the script boilerplate. Carlos, this may help you find your router config info. --<cut>------------------------------------------------------------------ #!/bin/sh # finddirs_by_latest_file.sh 2022-06-30 rw # # Outputs a list of directories of found files, sorted by the time of # their most recently modified file, and prefixed by a file count. #-----<lib/s/template-errx-getopts.sh>----------------------------------- CMD=finddirs_by_latest_file VERSION=0.1 export LC_COLLATE='C' Cmd=`basename "$0"` umsg() { #------<USAGE>--------------------------------------------------------- printf 'usage: %s %s\n' \ "$Cmd" '[--sdir] [find_options] <find_starting_point>...

[oS-en] Obtaining external IP
by Carlos E. R. 02 Mar '23

02 Mar '23

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I use "checkip.dyndns.org" to obtain my router external IP in scripts. I don't have yet IPv6, but my question is, can someone that does have IPv6 test it and find out if it writes the IPv6 address? And if not, is there an alternative query site to find that one, suitable for scripts? Thank you. - -- Cheers Carlos E. R.

A little bit weird - /etc/resolv.conf is not being populated
by Per Jessen 01 Mar '23

01 Mar '23

>From the mythv thread - I have just repeated this issue, on Leap 15.1. (I know its EOL, but I don't have a choice). a) after rebuilding the initrd, the first boot - just the standard template in /etc/resolv.conf, no nameserver. firewalld is running. b) 2nd reboot, no changes. Still an empty /etc/resolv.conf. The wicked lease information is from last night. c) stopped and disabled firewalld, 3rd reboot. Now the lease info was updated and so was /etc/resolv.conf. Weird stuff. d) enabled firewalld and rebooted. Empty /etc/resolv.conf. I would try this out on 15.4 and 15.5, but NFS installations don't work. I guess I could do a zypper dup. Anyone have any suggestion as to how or why firewalld might interfere with the populating of /etc/resolv.conf ?? Surely that's crazy. -- Per Jessen, Zürich (1.5°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

systemd override requires= ?
by Per Jessen 28 Feb '23

I'll just throw this out here, I'm still researching - I have a service unit that has: Requires=mysql.service I'm trying to override this to "Requires=" (i.e. nothing) with a drop-in, but I'm not having any luck. I keep getting: mythbe2:/etc/systemd/system # systemctl start mythbackend Failed to start mythbackend.service: Unit mysql.service not found. I can override it to something different, but how do I just remove it ? -- Per Jessen, Zürich (1.0°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

packman leap 15.4 - no mythtv ?

having finally managed to boot 15.4 from nfs root, I started looking for mythtv. It was available from packman up until 15.3, but I can't find it for leap 15.4 ?

Excellent printer compatibility: Brother MFC-L3770CDW
by Stakanov 26 Feb '23

26 Feb '23

Since a lot of users come and ask advice on printers, having found one working really well with Leap and TW, I wanted to share this experience about a multifunction printer with print/scan/fax function. The Brother MFC-L3770CDW has an automatized feed, double sided copying/fax and is fitting for mid size volumes (small home office, club, smaller organizations). The volume is limited by the price of the cartridges, for high volume there are better solutions. TW / Leap: very good compatibility with the driver installation following the following howto of opensuse: https://en.opensuse.org/SDB:Brother_How_to_setup_a_Networked_Printer_Scanner The machine performs extremely well and if you own a voip to isdn gateway you can also use it as a well working fax offering standard/fine/superfine/foto . Within the selection of scanners the multfunction printer is visible with all features, printer and fax also. This is true for Leap 15.4 and TW. So if you need a LED printer with excellent print quality, colour and b/w as well as automated feed, scan of multiple also double side pages and compatible to a 100 % as it seems with your opensuse machines, this is my advice. The only drawbacks are a slightly higher price for cartridges than e.g. some Lexmark and a slightly lower speed for doublesided scan jobs. As these run without your presence (at least if the pages do not have a paper jam) the latter point should be negligible for private and SOHO users. The printer/scanner has also a normal "scanner" field for use with oversized or rigid document. I would not recommend it for photos where, at least for me, a nice flatbed scanner is till the best high resolution solution. I hope this is the right group for such a message and that I do not cause high blood pressure to some, for the terrible loss of bits and bites. But as people regularly ask for advice, well this is mine. Regards, S.
