Hi, I'm trying to help to an elderly person which uses Debian stretch to access the gov.il interface, she has the biometric id card and I have a generic smart card reader (GemPC Key SmartCard Reader) that I wished to give her so she could auth to the system. I don't have a biometric id , so I can't verify if we can even use the browser to access the web interface. Does anyone have a biometric id , and can check if they can login using FF / chromium or stuff like that ?

off topic (but I don't know who to ask) - probably?? ISP problem
by Shlomo Solomon 02 Jun '24

I teach computer networking and the latest assignment I gave my students was to use Python and Scapy to emmulate traceroute. The code is simple: - send an ICMP packet with TTL = 1 which will fail but return the first hop address - continue sending ICMP packets - each time increasing the TTL to get the next hop - if the ICMP reply is NOT an error, we have arrived. None of my student submissions worked, which was strange, so I tried my own code which I know is correct. It also did not work. The error messages arrive for each hop, but it seems that the NO ERROR message (when the destination is reached) is not arriving. I also checked with Wireshark and see error replies (as I should) for each hop, but then (when I assume I have reached the destination) there is no reply. I then tried disconnecting my computer from my ISP and connected via a Hotspot on my phone - PROBLEM SOLVED. So this seems to be a problem with my ISP (019) blocking some traffic. But I don't know what the next step is. If I call customer service, I'm sure no-one will understand what I want. BTW - ping and the "real" traceroute work fine. I also looked at router settings, but did not find anything suspicious. Can anyone suggest how to explain my problem to my ISP? ALSO - if there is anyone using 019, I would be happy to send my code for testing to verify that this is really a problem with 019. -- Shlomo Solomon http://the-solomons.net Claws Mail 4.0.0 - KDE Plasma 5.24.7 - Kubuntu 22.04

Do up-to-date Nvidia drivers suppress output to DVI interface?
by Omer Zak 31 May '24

My Linux desktop has two displays (DELL and Samsung), Nvidia GP107 (GeForce GTX 1050 Ti) with HDMI and DVI outputs. The operating system is Linux Debian Bullseye (version 11.9). Today I upgraded the Nvidia proprietary drivers from version 550.54.15-1 to version 555.42.02-1 (several .deb packages) and as a result, only the HDMI-connected display works now in X-Window. When the computer boots, the text display is via the DVI screen, and when X-Window works, the DVI screen displays nothing and information is displayed on the HDMI-connected screen. The output of 'xrandr | grep connect' is as follows: DVI-D-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 476mm x 267mm HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm I saw no obvious error messages in /var/log/Xorg.0.log nvidia-smi does not display anything abnormal. glxgears works on the screen connected via HDMI. I tried few versions of /etc/X11/xorg.conf (/etc/X11/xorg.conf.d/ is empty) including having no xorg.conf at all. All of them yield the same results (only the HDMI-connected screen displays stuff). Questions: 1. Does anyone know if Nvidia disabled, in version 555.42.*, their DVI support or changed its configuration options? 2. What, if any, configuration options should I check?

Hi all, The Wednesday, 5/1/2024 GoLUG meeting commences at 7pm Eastern Daylight Time online at meet.jit.si/golug . I'll be late because of my kids' birthday (this happens every May), but when I get there I'll show a simple no Javascript, CSS-only web-menu and a 100% CSS, no graphics knockoff of the logo from TV show Law & Order. This gives plenty of time for others to show off various interesting tricks they've created. Hope to see you there.
