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(the driver source was fetched by git from its current github repo, so it's not out of date, it's in fact newer than the above blog post) What gives more clues is the small piece of thermal paper that came with the printer with a printout of its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

[FC8] ssh and CAC card???
by Todd Denniston 17 Sep '24

17 Sep '24

From what I understood, the change to openssh listed in: rpm -q --changelog openssh |less as: "* Wed Jun 20 2007 Tomas Mraz <tmraz(a)redhat.com> - 4.5p1-7 - experimental NSS keys support - correctly setup context when empty level requested (#234951) " was supposed to allow the Common Access Card (CAC) to work with the shipped Fedora 8 ssh. As per NSS usual, everything is undocumented, i.e., `ssh-add --help` does not help at all, and `man ssh-add` points to `ssh-add -s reader` # ssh-add -s 0 Enter passphrase for smartcard: SSH_AGENT_FAILURE Could not add card: 0 # ssh-add -s 1 Enter passphrase for smartcard: SSH_AGENT_FAILURE Could not add card: 1 So does anyone know how to use the possible functionality, or are we reduced to reading the source? -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter

Apache fails to resume after hibernation
by Patrick O'Callaghan 07 Sep '24

07 Sep '24

I've noticed recently that Apache often (or perhaps always) doesn't respond after a system hibernate/resume cycle. After restarting it ('apachectl restart') all is well. I could script an automatic restart after resuming, but I wondered if this is a well-known problem with a simpler solution. poc

This list's search engine not working?
by HaJo Schatz 22 May '24

22 May '24

Ever since I stumbled across this list, I seem to have major difficulties searching the archives. Say I want to see my posts to the list (they all have the same footer as below), I believe I could go to http://www.redhat.com/archives/fedora-list/ and enter "HaJo" as a search string. Searching in all sections, I get 0 results. Does the search engine ignore me by some reason? BTW -- I've been posting since about June, and when showing the archives sorted by author, I do find my posts. OK, not the most helpful to search for my own posts, but I do have the same issue when searching for given topics. Any other search engine out there indexing this list reliably? Google shows 0 hits on a "site:www.redhat.com/archives/fedora-list/" search... -- HaJo Schatz <hajo(a)hajo.net> http://www.HaJo.Net PGP-Key: http://www.hajo.net/hajonet/keys/pgpkey_hajo.txt

Hi Michael, --- Michael Folin <michael.folin(a)donator.se> wrote: > how do I install Tomcat i fedora? > can't find it during the installation > If you mean during the installation of Fedora Core itself, then I don't think Tomcat is provided with Fedora Core (please feel free to correct me if I'm wrong). This means you will probably need to download Apache Jakarta Tomcat (either binaries, or the source which you'll need to build) and install it. Hope this helps.

F38: systemd-resolved.service oddity
by Ranjan Maitra 22 Oct '23

22 Oct '23

Dear friends, From the past week, I have had an issue in that after several hours, some particular sites become inaccessible to me, and can only be accessed if I use restart using sudo systemctl restart systemd-resolved.service What particular issues cause this? Why did it start a week ago, and has become quite reliable in its annoyance? (I have to say that when I can no longer access this site, I am no longer on Cisco SecureClient VPN, which is also one of the sites which can not be accessed with Cisco SecureClient VPN without restarting systemd-resolved.service, and the site is my worksite domain). Happy to file bug reports, and to test different things. I am on a fully updated F38. Many thanks and best wishes, Ranjan

battery life
by Matt Morgan 10 Oct '23

10 Oct '23

I have a new HP Victus laptop with Fedora 38 and Windows 11 installed. In Windows, the battery lasts all day--8+ hours. In Linux, it lasts about 2.5-3 hours. I installed TLP, which I remember from way back, although I don't know if that's what people do these days. In any case, it didn't help. What else can I do to get Fedora not to eat up the battery life so fast? Thanks, Matt
