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

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 ?
by Per Jessen 27 Feb '23

27 Feb '23

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 ? I'm looking for mythtv-backend, later probably also mythtv-frontend. -- Per Jessen, Zürich (13.5°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes

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.

Wireless mouse pressing scroll wheel doesn't paste
by Jeffrey Taylor 25 Feb '23

25 Feb '23

I think this happened when I updated from Leapt 15.4 to 15.5. I used to be able to click and hold the left button to copy text and press middle button (scroll wheel) to paste. This is on XFCE. I find plenty of pages telling how to disable this and the middle button emulation on 2 button mice but not how to enable on a 3 button mouse. TIA, Jeffrey

SSH connection with publickey no longer works
by Freek de Kruijf 24 Feb '23

24 Feb '23

Hi, I have a Tumbleweed system which makes a backup each night to a Leap 15.4 system, both use aarch64 architecture. I use publickey for authentication, which worked until recently. Both are up-to-date with the latest updates. On the Tumbleweed system I have: # ls -l .ssh/id_* -rw------- 1 root root 1381 21 feb 12:34 .ssh/id_dsa -rw-r--r-- 1 root root 608 21 feb 12:34 .ssh/id_dsa.pub On the Leap 15.4 system I have: rpi4-154:~ # ls -l .ssh/authorized_keys -rw------- 1 root root 2962 feb 21 12:39 .ssh/authorized_keys with the content of id_dsa.pub. The start of the content is: ssh-dss AAAAB3NzaC1kc3MAAACBAIxtorhRWGDeP6L01o83+LgSL9DYcYAXozXtl1cknkfbO To test the way the connection is made I give the command: ssh -v -p xx root@<leap_14.4> Which gives me debug output. After negotiation for the ssh connection the output shows the start of the publickey negotiation, which immediately starts with: debug1: Skipping ssh-dss key /root/.ssh/id_dsa - corresponding algo not in PubkeyAcceptedAlgorithms A few lines further on I have: debug1: kex_input_ext_info: server-sig-algs=<ssh-ed25519,sk-ssh- ed25519(a)openssh.com,ssh-rsa,rsa-sha2-256,rsa-sha2-512,ssh-dss,ecdsa-sha2- nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,sk-ecdsa-sha2- nistp256@openssh.com,webauthn-sk-ecdsa-sha2-nistp256@openssh.com> in which ssh-dss is present. It goes on with: debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password,keyboard- interactive debug1: Next authentication method: publickey But then a number of "debug1: Trying private key: /root/.ssh/id_*" where id_dsa is not present. It continues with: debug1: Next authentication method: keyboard-interactive So it asks for a password and authorization with publickey no longer works. Previously I tried "ssh-keygen -t ecdsa" which did not work either and the one that I used, which worked, was of the type rsa. Any ideas? Bug? -- fr.gr. member openSUSE Freek de Kruijf

Leap 15.5 - looking good
by Per Jessen 23 Feb '23

23 Feb '23

Apart from my own fat fingers, the pxe install of 15.5 is going well. currently less than 200 of 900 packages left. context - pxe+ssh install, from local mirror, root+home filesystem is jfs. Okay, all done before I finished typing. Slightly exotic - I'm trying to boot with lilo, and I can't even run lilo. "No such file or directory". (booted installer, chroot into new system with bind mounts): discompi8:/ # lilo -V bash: /sbin/lilo: No such file or directory discompi8:/ # l /sbin/lilo -rwxr-xr-x 1 root root 186896 May 16 2020 /sbin/lilo* discompi8:/ # strace lilo -V execve("/sbin/lilo", ["lilo", "-V"], 0x7ffc8e28c2e8 /* 40 vars */) = -1 ENOENT (No such file or directory) strace: exec: No such file or directory +++ exited with 1 +++ Granted, I have probahly not installed anything on real iron with lilo in two-three years or more, I must be missing something. -- Per Jessen, Zürich (12.8°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
