monitoring of fed/web severs
by bruce
Hi.
To all you sys admin -- real or just good!
I'm doing some thought/research prep to figure out what's required to
monitor remote (cloud) web servers, and the services running on the
instance.
Ie, what apps/services should be used
-3rd party apps running/pointed to the box
-what should be tracked/monitored?
-are there "recipes" to use to be used as a starting point?
-things "not" to do -- things "to" do..
Good/Better/Best practices...
Server security processes
User attacking the server
Traffic attacking the web Server process..
Whatever the list has to offer, I'd be interested in seeing/hearing.
thanks much
ps. The use case is a couple of test servers, running different
webSites, with different mysql db. The apps will be php/javascript for
the most part.
thanks!!

USB device detected but can't access
by Alex
Hi,
I have a SanDisk Ultra Flair USB 3.0 device that doesn't appear to be
properly recognized. It doesn't appear in an "fdisk -l" output and not
automatically mounted on the filesystem as other devices are. It does
appear to be detected, however:
[498296.376209] usb 2-3: USB disconnect, device number 7
[498298.800214] usb 2-3: new SuperSpeed USB device number 8 using xhci_hcd

idProduct=5591, bcdDevice= 1.00
[498298.812867] usb 2-3: New USB device strings: Mfr=1, Product=2,
SerialNumber=3
[498298.812871] usb 2-3: Product: Ultra USB 3.0
[498298.812874] usb 2-3: Manufacturer: SanDisk
[498298.812877] usb 2-3: SerialNumber: 4C530001030516102474

[498298.983388] usb 2-3: reset SuperSpeed USB device number 8 using xhci_hcd
It's not that old, and certainly doesn't have many hours on it. Are there
any other ways I can try to access it before determining it's defective?

With kernel-6.5.5 flatpaks don't start
by Jürgen Botz
After doing 'dnf upgrade' on my Fedora 38 Thinkpad and then rebooting into new 6.5.5 kernel yesterday no flatpaks would run. The 'flatpak' command itself was fine, i.e. I could do 'flatpak list' and even 'install', but 'flatpak run ...' failed for all flatpaks I tried. Rebooted back into older kernel (6.4.15) and everything was fine. Haven't had time yet to investigate further, yet, but I'll have another look this weekend... for now I wanted to see if anyone else has experienced this?

Creating a ScreenShot HotKey Script
by Philip Rhoades
People,
I want to scroll through doc pages in a script loop doing a screenshot
for each page eg the procedure would be:
1. Display the first page of the doc you want to screenshot.
2. Hit CTRL-PrtScrn (say) to start the script loop.
The script does a screenshot of the current screen.
The Right Arrow or PageDn key is sent from the script to advance the
doc to the next page.
The script continues to loop . .
3. The script is stopped by CTRL-C (say).
Is this possible? Should I be trying to do this from Sway?
Thanks,
Phil.

can't ping
by Mike Wright
Hi everybody,
I have no idea how I got in this mess, but I've lost the ability to use
ping as a regular user. sudo still works.
Nothing in lsattr, regular perms are 755 no suid.
ping: socktype: SOCK_RAW
ping: socket: Operation not permitted
ping: => missing cap_net_raw+p capability or setuid?
Any help? Especially ideas on how I managed to do this?
Thanks

Current Stable Fedora Version?
by Stephen Morris
Hi,
I am currently on F38, but the other day when I was searching for
how to do something (which I've forgotten what it was) I found
instructions for F39 and F40. So I'm now curious as to what is the
current stable version of Fedora?
regards,
Steve

EFI and fedora
by Bill Cunningham
In the days of mbr bios we could save the 512 of the HDD sector.
Now is all this gone with UEFI? Is the bootsector of the partition, 512
to 1024 or so bytes no longer valid? IS there specific locations that
uefi files are stored in binary of the drive? Or, is that all gone now
and we are just looking at files in text in partitions like boot/efi ?

Hung Virtual Machine
by Robert McBroom
Power outage dropped my f38 system while a virtual Rawhide system was
running. On restart the virtual machine is paused and none of the
virt-manager shutdown, reset or delete work. It wasn't supposed to come
up on a host restart. What can be done to clear the lock?

I want to generate randomly generated triangles from points as in

any suggestions as to why it does not run? Do I need to use oracle's java? does openjdk no longer work.
Thank you in advance.
