securing this workstation.
by home user 19 Oct '25

19 Oct '25

(Fedora-42; stand-alone workstation) This is a totally new Fedora install on a stand-alone workstation, done today. It is not a part of a LAN or WAN or any other home or office network. It is not dual-boot. I do need for Firefox, Thunderbird, and dnf to be able to interact with the "outside world" appropriately. I do occasionally need to be able to download or upload things. Beyond those (and maybe other appropriate things that don't at the moment come to mind), I do not want anyone or anything to be able to get into this workstation. For example, no "ssh", "scp", "rlogin". I gather from the Fedora docs that I should use firewalld or firewalld-config. I have both. But Fedora docs does not give me enough detail. I am not an IT professional. What specifically should I do to keep unwanted people and things out?

This error pops up whenever my system boots up. Clicking on [Details <<] produces a message box with the single entry "Details" in it. What's happening? Thanks - jon

ESC/P thermal receipt printers and Linux...
by Fernando Cassia 19 Aug '25

19 Aug '25

Running dmesg after plugging my POS-5890K labelled usb thermal receipt printer, it identifies itself as full-speed USB device number 9 using ehci-pci idVendor=0416, idProduct=5011 Mfr=1, Product=2, SerialNumber=3 Product: POS58 USB Printer Manufacturer: GD32 Microelectronics SerialNumber: Printer I found the hard way that these printers are not supported by CUPS by default ... one has to go the extra length to either send esc/p codes manually via your own app http://kg4zqz.blogspot.com/2016/08/escposf-thermal-printer-filter-and.html ...or compile a driver from source, just like 20 years ago for some printers... maybe 2018 will be the year of desktop linux *sarcasm* I've tried this driver and it didn't work... http://scruss.com/blog/2015/07/12/thermal-printer-driver-for-cups-linux-and… (the driver source was fetched by git from its current github repo, so it's not out of date, it's in fact newer than the above blog post) What gives more clues is the small piece of thermal paper that came with the printer with a printout of its self-test (surely from Windows). It reads: 58-IV-U Thermal Printer Version: 58.E-Z04-AA Revised date: 06-Jan-2017 Command Standard: EPSON (ESC/POS) Print mode: Normal mode & Hex Mode Print method: Line Thermal Print width: 384 dots/line Print speed: 90 mm/s Chinese Mode: NO Print density: Level3 Current Codepage:0 Interface Type: USB Current Character: Chinese (GB18030) Alphanumeric Code Page: 0: OEM437 (Std.Europe) 1: Katakana 2:OEM850 (Multilingual) (…) 96:(Thai2) I wonder why the CUPS folks have not released a generic “EPSON ESC/POS” printer driver where the above parameters can be tweaked and entered manually. The driver mentioned above was compiled, and installed but didn’t work. A sample print gave gibberish. A second text-only printing (by clicking the CUPS “print self-test page” read “IF YOU CAN READ THIS YOU’RE USING THE WRONG DRIVER FOR YOUR PRINTER”. A crude bug-finding code it seems… Any ideas before I head over to the CUPS maling list and pull my hair? For instance, this blog post https://mike42.me/blog/2015-03-getting-a-usb-receipt-printer-working-on-lin… talks about using "usblp" but commenters say "usblp" was deprecated (already in 2015) So what does replace usblp? And look, here someone else also pulling his hair. https://stackoverflow.com/questions/45926734/raw-cups-printer-how-to-avoid-… FFS, a line printer was the first type of printer, back in the days of RS232 ports. If we can't get a USB line printer detected and configured and send ASCII to it, we're doomed. All because there's a dozen poorly documented layers of software crap obscuring it... FC

BIOS update, grub boots, Fedora doesn't
by Go Canes 28 Jun '25

28 Jun '25

I recently updated the BIOS on a new Dell XPS 16 running Fedora 40. Prior to the update everything was working fine. After the update, grub displays the boot menu and indicates it is booting the default entry, then...nothing. I have performed the following tests and/or remedial actions: - attempted to downgrade the BIOS - the updated version does not allow downgrading - no change if secure boot is enabled or disabled - confirmed the boot disk (NVMe) is in AHCI mode (not RAID) - tried disabling extra C-states in BIOS - no change - BIOS has self-tests, they all pass - booting older kernels including the rescue kernel do not change the behavior (other than the grub output as to which kernel is being booted) - booting Ventoy works and lets me select other images to boot - booting a f40 netinstall ISO(via Ventoy) (the same one used to instal Fedora 40 on this laptop initially) gets as far as the "install/test/rescue" menu, but otherwise has the same boot failure - booting a f41 netinstall ISO (via Ventoy) has the same behavior as the f40 netinstall ISO - booting clonezilla (via Ventoy) gives multiple messages about trying to read or write outside of the partition - booting a Raspberry Pi x86 ISO (basically a live image) (via Ventoy) displays several boot messages before the system hangs - booting a NetBSD ISO (via Ventoy) displays several boot messages before eventually displaying a "privileged instruction fault" trap and dropping into a debugger Out of all of the above, the only thing that made me go "hmm" was the partition errors from clonezilla, so I did a test where I disabled the NVMe disk and attempted to boot off of a known, good Fedora install on a USB drive. This also failed. My theories and where they break down: - CPU issue: everything boots and works, up to a point, and the BIOS self-test passes. - RAM issue: everything boots and works, up to a point, and the BIOS self-test passes. - NVMe issue: grub boots, and if I disable the NVMe drive, the boot failures persist anyway. Any suggestions?

dump/restore ftruncate?
by ToddAndMargo 09 May '25

09 May '25

Hi All, Fedora 41 dump-0.4-0.57.b47.fc41.x86_64 When restoring file(s) with `restore`, I get a lot of these messages: restore: <name unknown>: ftruncate: Invalid argument restore: <name unknown>: ftruncate: Invalid argument and on and on and so forth. Everything comes back okay. Is this anything to fret about? Many thanks, -T -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When we ask for advice, we are usually looking for an accomplice. -- Charles Varlet de La Grange ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

suppose I remove nvidia card?
by home user 08 May '25

08 May '25

(F-42 stand-alone workstation; gnome) good morning, My F-42 workstation had 21 mixed crashes in a few hours late yesterday, and more in a matter of minutes just a few minutes ago. It was installed yesterday afternoon. It's practically unusable. I'm now on a windows-10 box (separate hardware, no dual boot). In my "securing..." thread, Samuel said: "...Anaconda won't install the proprietary NVidia drivers, so you must be using nouveau. If it works, then great. If you have issues, you might want to install the drivers from rpmfusion." I don't know if the crashes are related to using nouveau, or due to something else. I do not game. The most graphics-intense thing that I do (as far as I know) is watch youtube videos with a resolution of about 1.4k. So I'm wondering... Suppose I remove the graphics card (nvidia GeForce GTX 660; 12 years old) entirely. 1. What do I lose by going without the graphics card? What are the risks? 2. Would I have to install Fedora-42 Workstation all over again?

Resolving names

Help. Looking at the about systemd-resolved question prompted me to try to clear a problem I am having with local DNS. My home system have few pcs and other devices, some of them with static ip addresses set at my local router. My situation is that name resolution does not always work. For example, if I do pepebuho@pepewin:~$ dig bloody ; <<>> DiG 9.18.33 <<>> bloody ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 61697 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;bloody.

I just work around it by using the ip addresses directly, but I remember it used to work several versions away. How can I make it work again? I tried to solve it using grok as a helper but could not make it work. -- ------------------------------ /\_/\ |O O| pepebuho(a)gmail.com ~~~~ Javier Perez ~~~~ While the night runs ~~~~ toward the day... m m Pepebuho watches from his high perch.

install and grub question
by François Patte 30 Apr '25

30 Apr '25

Bonjour, I have a f40 install on one disk (say /dev/sdc) and I want to install F42 on /dev/sda. I suppose that after the installation grub will propose to start f42 from the new disk, how can I add to grub the now old f40? Is there a step during the install process of f42 to say that I want to add f40 to grub? Thank you F.P.

Hello, If I am correct, there was a sagemath package in the past, but it seems that it is not available anymore. Could somebody clarifies the situation?
