NFS4: CentOS 7 client with a Fedora 32 server
by Braden McDaniel 27 Jul '20

27 Jul '20

I'd like to support a CentOS 7 client from a Fedora 32 NFS4 server. Other Fedora 32 clients can mount the volume just fine using: $ mount -t nfs4 my-server:/my-export-root/foo /foo But when I try this from a CentOS 7 client, I get: mount.nfs4: Operation not permitted Is there any bit of configuration I can do on the client and/or server to make this work, short of allowing fallback to pre-4 NFS versions? -- Braden McDaniel <braden(a)endoframe.com>

Where are the microcode updates for Crosstalk in F32 ?
by Sreyan Chakravarty 27 Jul '20

27 Jul '20

Hi, Well guys, its time to panic once again. I just found out my system is vulnerable to the new Crosstalk vulnerability by running the popular Meltdown OVH script. More about the vulnerability over here: https://www.vusec.net/projects/crosstalk/ These exploits get worse each time, this one affects all cores. This is how I tested for the vulnerability. Downloaded spectre-meltdown-checker.sh via : wget https://meltdown.ovh -O spectre-meltdown-checker.sh and then just executed with sudo. This is the output I got: * SRBDS mitigation control is enabled and active: NO > STATUS: VULNERABLE (Your CPU microcode may need to be updated to mitigate the vulnerability) CVE-2020-0543:KO Full output here: https://pastebin.com/raw/hyfFBbaF As you can see the tool specifies that my microcode is not the latest. That being said, where do I find the latest microcode from ? My OS is fully updated, and the firmware and microcode is also latest according to DNF: $ sudo dnf update linux-firmware Dependencies resolved. Nothing to do. Complete! $ sudo dnf update microcode_ctl Dependencies resolved. Nothing to do. Complete! So where is the microcode update in Fedora for this ?? Canonical has already published microcode updates for this, as shown here: https://youtu.be/UR-5vAZ1cGg?t=1160 <rant> It kind of seems frustrating that a bleeding edge distro like Fedora still hasn't provided updates yet. While Ubuntu a distro that doesn't always use the latest software already has a fix. </rant> What can I do now ? What is progress for Fedora ? Will the microcode from Canonical work for Fedora ? Dumb question I know but I am desperate. Let me know if any further info is required. Some more info about my CPU: https://pastebin.com/raw/TNJS930F What is everyone else in the community doing about this ? Thanks. -- Regards, Sreyan

gnome control center wifi madness
by Tom Horsley 26 Jul '20

26 Jul '20

If I bring up the gnome control center wifi page, it always says "no adapter detected". If I turn on wifi, it shows me a list of SSIDs to connect to, and I can connect. If there is no adapter detected, what am I talking to? :-).

Steam erroneously marked as "Installed" in Gnome Software
by Sreyan Chakravarty 26 Jul '20

26 Jul '20

Hi, I have NEVER installed Steam via Gnome Software on my notebook, in fact I never installed it ever, but on Gnome Software it is marked as "Installed". Any way I can remove it from there ? That is mark it as "not installed" ? When I click on "Remove" it says "no packages to remove" but it has "Launch" and "Remove" options enabled. "Launch", does nothing. Are there any command-line/debugging/troubleshooting options that I should know about for Gnome Software Centre ? Seems like I haven't seen the last of such annoying bugs. Thanks. -- Regards, Sreyan

DNF, Rpmfusion -

I guess this means rpmfusion is running behind, or does it imply something else?

USB to Ethernet LAN -
by Bob Goodwin 24 Jul '20

24 Jul '20

I have a WD 4TB external hard drive connected to my Fedora32 computer on which I have been saving data. It connects via USB, has no ethernet port (I am not the one who bought it) and I would like to make it available on my LAN. Is there any way to do it with software? -- Bob Goodwin - Zuni, Virginia, USA http://www.qrz.com/db/W2BOD FEDORA-32/64bit LINUX XFCE Fastmail POP3

nmcli won't save VPN password
by Sam Varshavchik 23 Jul '20

23 Jul '20

I'm trying to save an OpenVPN password via nmcli, in Fedora 32. I believe I should be executing: nmcli connection modify CONNECTIONNAME vpn.secrets "password=[PASSWORD]" So I execute this as root, and this initially produces very promising noises in /var/log/messages: Jul 22 20:41:35 jack NetworkManager[1525]: <info> [1595464895.3350] audit: op="connection-update" uuid="UUID" name="CONNECTIONNAME" args="vpn.secrets" pid=67812 uid=0 result="success" However, the password appears to disappear into a black hole: nmcli --show-secrets connection CONNECTIONNAME | grep secrets vpn.secrets: -- And nmcli connection up fails because there's no password. The VPN connection's configuration was imported from the VPN provider's supplied ovpn file, via "nmcli connection import". Some searching around found some hits suggesting that my /etc/NetworkManager/system-connections/CONNECTIONNAME should have a [vpn- secrets] section, but mine does not. If I add it, run "nmcli connection reload", "nmcli connection modify", that just removes the [vpn-secrets] section. What would be the right way to do this?
