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.

Sane Scanner Resolution Configuration
by Stephen Morris 21 Jul '20

21 Jul '20

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. Two of the options are for the horizontal and vertical scan resolution, which by default are set to 75. These options are reflected in the xsane gui, but they are disabled so I can't alter them from the gui, I have to edit the config file and specify the resolution I want in there. Where can I find documentation on the format of that xsane config file, that would tell me how I get the list of resolutions the scanner supports into that config file so that they are selectable by a dropdown in the xsane gui? regards, Steve

whereis 'Users Settings Tool'
by Geoffrey Leach 21 Jul '20

21 Jul '20

The doc for Fedora 32 makes reference to a 'Users Settings Tool' accessible (secretly) from the Settings tool. It does not appear to be available. Any idea why? Or where there might be a similar GUI?

According to Thunderbird.net, "Thunderbird version 78.0 is only offered as direct download from thunderbird.net and not as an upgrade from Thunderbird version 68 or earlier." -- https://www.thunderbird.net/en-US/thunderbird/78.0/releasenotes/ What's the plan for Thunderbird in the Fedora repo going forward? -- -- Steve

What is Portal and pipewire and Why Did They Start?
by Garry T. Williams 20 Jul '20

20 Jul '20

A few weeks ago I installed F32-KDE fresh on a workstation (a disk drive failed). All of a sudden last night Portal service was started (whatever that is). I did nothing that I know of to trigger this. Furthermore, since updating after installing this system, that service has never been started until now. Directly after the Portal service started, I see error messages coming from pipewire (whatever that is). Can anyone tell me what this is all about and why it happens now? (I'm especially concerned about why it started.) Jul 16 00:20:59 vfr systemd[1168]: Starting Portal service... Jul 16 00:20:59 vfr systemd[1168]: Starting flatpak document portal service...

reboot after upgrade? and best practice
by Anil Felipe Duggirala 20 Jul '20

20 Jul '20

hello everyone, I would like to ask what is the best practice for upgrading (updating all packages, ie. "dnf upgrade") in my Fedora 32 Workstation. The Gnome Software graphical application provides a way for me to do this, but it can also be achieved in the command line. Do these two methods achieve exactly the same results? I would also like to plainly ask if in any occasion it is necessary or advisable to perform a system reboot after doing an "dnf upgrade". I have noticed that when the upgrade is performed with Gnome Software, a reboot is always performed after the upgrade. thank you,
