Re: Sane Scanner Resolution Configuration
by Mike Flannigan 23 Jul '20

23 Jul '20

Sure thing. The 'xsane.rc' file at ~/.sane/xsane is copied here: http://www.mflan.com/temp/xsane.rc There is also a 'xsane.mdf' file in there, but I don't think you need that. There is also a 'CANON:Canoscan9000FMarkII.drc' file in there and it is copied here: http://www.mflan.com/temp/CANON:Canoscan9000FMarkII.drc Mike On 7/21/20 10:09 PM, users-request(a)lists.fedoraproject.org wrote: > Thanks Mike, that's interesting, my Xsane ver 0.999 doesn't provide > the same functionality.

bizzare dual-monitor behavior
by Greg Woods 22 Jul '20

22 Jul '20

Let me start by saying I have used this same setup literally for years now and have not seen this new issue until yesterday. I have a dual monitor setup. One of the monitors is controlled by a KVM switch; the machines that have only a single graphics port use this monitor via the KVM switch. The other monitor has two HDMI ports that are connected to two computers directly, bypassing the KVM switch; I just switch the second monitor manually between the two as needed. What used to happen when I switched to a different computer is that I can use the new computer using the first monitor, the mouse and the keyboard, just as usual. The second monitor, unaffected by the KVM switch, will continue to show the image it is getting from the dual-monitor system. I am used to this; sometimes I even use it to my advantage when the monitor is showing a web page or something that I can still see while working on a different computer. But, what is now happening (since yesterday) is that when I switch to a second computer, the non-KVM-switched monitor now flashes off and on every few seconds (and just keeps doing this seemingly forever; I did leave it this way for more than 15 minutes last night) . This is INCREDIBLY annoying and makes it impossible to make any use of the image displayed there. Another oddity is that this is NOT happening with the other dual-monitor machine. That system is a Dell laptop in a dock. The system with the issue is a fairly new desktop (which did not exhibit the issue for the first few days of use, it suddenly started yesterday). Both systems are running Fedora 32 (but of course they have very different hardware). I normally use GNOME on Xorg, but I have tried plain GNOME (Wayland) and Cinnamon too and the problem exists there as well. I briefly tried Plasma, but that results in a solid green screen, and when I switch back to the two-monitor system, the first monitor is solid green too and none of the keys respond, so I had to use a remote ssh shutdown to recover. Has anyone ever seen anything like this and know what I could do to stop it? Thanks, --Greg

Printing failure -
by Bob Goodwin 22 Jul '20

22 Jul '20

Earlier today I discovered that I could not print from this Fedora 32. It has always printed without a problem. The printer is Ethernet connected to my LAN. I have gone through the setup with cups, the fedora/gnome admin app, and now the Brother liinux install tool. Cups shows: HLL5100DN <http://localhost:631/printers/HLL5100DN> HLL5100DN Brother HLL5100DN for CUPS Paused - "could not create directory "/root/BRF": Permission denied" The Brother install tool quits when it tries to make a test print and finds it can't see the printer: lpadmin -p HLL5100DN -v cups-brf:/ -E Test Print? [y/N] ->y wait 5s. lpr -P HLL5100DN /usr/share/cups/data/testprint ls: cannot access '/etc/udev/rules.d/*.rules': No such file or directory ls: cannot access '/etc/udev/rules.d/*.rules': No such file or directory Hit Enter/Return key. I began writing this yesterday, this morning we tried and were able to print from a Mac portable via wifi so that says the printer works at least. Something is corrupted in my computer it appears? And doing "ctrl p" fails with: > Cups shows: > HLL5100DN <http://localhost:631/printers/HLL5100DN> HLL5100DN > Brother HLL5100DN for CUPS Paused - "could not create directory > "/root/BRF": Permission denied" > > > The Brother install tool quits when it tries to make a test print and > finds it can't see the printer: > > lpadmin -p HLL5100DN -v cups-brf:/ -E > Test Print?

Alternatives link broken after package upgrade
by Terry Polzin 22 Jul '20

22 Jul '20

I've been dealing with this issue on a couple of my Fedora 32 machines. It appears that the upgrade of icedtea-web from icedtea-web-1.8.2-3.fc31.x86_64 to icedtea-web-2.0.0-pre.0.3.alpha13.patched1.fc32.x86_64 breaks the alternatives link to javaws.x86_64. I have to downgrade icedtea-web to be able to run JNLPs

What is the argument I need to properly pass a PCI or PCIe device to a podman container at runtime (podman-run)?

Re: Sane Scanner Resolution Configuration
by Mike Flannigan 21 Jul '20

21 Jul '20

My XSane ver 0.999 allows changing the resolution by selecting the dropdown on the main screen and selecting 75, 150, 300, 600, etc. http://www.mflan.com/temp/res1.jpg Mike On 7/21/20 4:08 AM, users-request(a)lists.fedoraproject.org wrote: > Subject: > Sane Scanner Resolution Configuration > From: > Stephen Morris <samorris(a)netspace.net.au> > Date: > 7/21/20, 4:08 AM > > To: > fedora <users(a)lists.fedoraproject.org> > > > Hi, > Having installed imagescan from Epson, and installed sane and > xsane, and edited the imagescan config file to specify the network > settings of my printer all-in-one, I now have xsane finding my > scanner, but this has highlighted a problem. > Having run xsane it has created Epson:ET-3700.drc in path > ~/.sane/xsane, which contains all the options used by xsane for > scanning.

More portal nonsense?
by Tom Horsley 21 Jul '20

21 Jul '20

Imagine my surprise to find this in my daily logwatch: df: /root/.cache/doc: Operation not permitted So I check it out: [root@zooty ~]# mount | fgrep doc portal on /root/.cache/doc type fuse.portal (rw,nosuid,nodev,relatime,user_id=0,group_id=0) More nonsense from portal and flatpak being dragged in?

F32 nftables hiccups
by ja 21 Jul '20

21 Jul '20

I have been attempting to use nft/nftables to blacklist ssh connections and have come across two problems. nftables-0.9.3-3.fc32.x86_64 kernel-5.7.8-200.fc32.x86_64 1. The "limit rate" syntax does not work correctly unless the "burst" value is set. counter add @saddr_rate { ip saddr timeout 2m limit rate over 4/minute burst 1 packets} counter \ update @saddr_blacklist { ip saddr timeout 10m } counter drop 2. The following syntax is not accepted by nft update @connection_count { ip saddr ct count over 3 } \ add @saddr_blacklist { ip saddr timeout 1m } drop nft_harting.nft:80:3-52: Error: Could not process rule: Operation not supported update @connection_count { ip saddr ct count over 3 } \ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I have been following a Debian mail list (amongst many) https://unix.stackexchange.com/questions/581964/create-dynamic-blacklist-wi… which implies that both of the above should work with the kernel/nft F32 versions installed. I attach the output of nft list ruleset (with the offending rule "{ ip saddr ct count over 3 }" commented out) (It includes the "set" definitions used above) Can anyone see any deliberate mistakes?

I have also just updated the extension pack to also 6.1.12, but I don't think the extension pack is what provides usb support (I thought the main usage of the extension pack is to get shared folders available) I thought the usb support was natively built in to virtualbox. In the machine settings in the usb section, I have 'Enable USB Controller' ticked, and then within that I have the radio button 'USB 3.0 (xHCI) Controller' selected, but that does not enable usb in virtualbox, any device inserted into a usb port is "mounted" under windows, and then I have to click on the usb icon in the virtualbox taskbar and then select the inserted device from the popup list to get the device into the linux virtual machine. Then once finised with the device do the same thing again to give the device back to windows. Please see https://www.virtualbox.org/manual/ch01.html#intro-installing as to information of what the extension pack provides.... Partially, from the page... Extension packs. Additional extension packs can be downloaded which extend the functionality of the Oracle VM VirtualBox base package. Currently, Oracle provides a single extension pack, available from: http://www.virtualbox.org. The extension pack provides the following added functionality: The virtual USB 2.0 (EHCI) device. See Section 3.11.1, “USB Settings”. The virtual USB 3.0 (xHCI) device. See Section 3.11.1, “USB Settings”. -- The key to getting good answers is to ask good questions.
