NFS4: CentOS 7 client with a Fedora 32 server
by Braden McDaniel
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?

Where are the microcode updates for Crosstalk in F32 ?
by Sreyan Chakravarty
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.

gnome control center wifi madness
by Tom Horsley
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
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.

DNF, Rpmfusion -

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

USB to Ethernet LAN -
by Bob Goodwin
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?

nmcli won't save VPN password
by Sam Varshavchik
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?
