question: does "diff" use short cuts?
by home user
When I try to verify a back-up, I use "diff -r". The directory trees being compared contain about 870 files (mostly binary, like PNG, JPG, and so on), and take up about 707 megabytes. The trees being compared are on the hard drive and on a USB-3 stick. When I run the "diff -r" command, it seems to finish too quickly - it seems like less than a half of a second. I saw similar results a few weeks ago comparing about 30 gigabyte trees on the hard drive vs. on a USB-3.1 stick; the results were practically instantaneous. Is diff actually checking every bit (or byte), or is it using some "short cut"?

fedora38 and Samsung ML-1740 USB Printer
by Alex
Hi,
I have a Samsung ML-1740 printer connected via USB that I managed to get
working with fedora37, but after a complete reinstall, I can't remember how
I did it, nor manage to figure it out.
I thought I located a PPD file, but now can't find one. I also recall
working with CUPS on the web backend, but I also tried changing some of
those settings and still can't get it to work.
Sending a document to printer gives every indication it has been printed,
including a message telling me the document was printed and the printer
actually warming up like it's going to print, except nothing ever comes out.
It only has a USB connection, so there is no IP address, so I can't use IPP
or other methods, correct?
The printer is literally 20 years old (manufactured in March, 2004), but
still works just fine. It does make it tough to configure, though. Any
ideas greatly appreciated.
Thanks,
Alex

Unable to Port Forward to a Virtual Machine
by Lists
I have a Fedora (35) workstation with some VMs running on a virtual LAN and I want to open
service(s) to the local Physical LAN. Goal is to make an HTTP service running on 192.168.122.11:80
visible to 192.168.1.* as 192.168.1.62:80
What am I missing!?!?
Office Network
192.168.1.*
192.168.1.62 Fedora Workstation IP
VirtD network
192.168.122.*
192.168.122.11 Virtual Machine IP
I have a script file as
firewall-cmd --add-service=http
firewall-cmd \
--add-forward-port=port=80:proto=tcp:toport=80:toaddr=192.168.122.11
firewall-cmd --add-masquerade
firewall-cmd --add-forward
firewall-cmd --add-port=80/tcp
and sysctll -p reports:
net.ipv4.ip_forward = 1
But when I attempt to get the service
wget http://192.168.1.62
Connecting to 192.168.1.62:80... failed: Connection refused.
Although I can get the service directly
wget http://192.168.122.11

dwagent suggested:
Based on the error message you shared with us in your last email, here is our suggestion:
It seems that the X11 Library is corrupted.
I did the check of the library (an reinstall it), but it does not help.
The libX11 is now -1.8.6 (fc38) while it was -1.7.3.1 in fc36.
Do you think that it maybe a bug in the new version of the X11 library?
Thanks.

OT: Ways to figure what causing High Ping Loss that require power cycling cable modem??
by Michael D. Setzer II
Island got hit with a Typhoon Cat 3/Cat 4 that caused lots of
damage to all internet providers. Power at house was out for a
week. They are still working on lots of issues.
Can figure when issue happens, and power cycle on cable modem
fixes it. Wonder if there might be some process to find way to
prevent it from happening or way to have script software reset
modem. Years ago had way to reboot Surfboard modem, but now
ISP using Arriss cable modems. Web access has no reboot option?
Thanks.
Usually would only need to reboot cable modem about once a
month, but over last 6 days, have required reboots average of 7.5
times a day? 45 total. Similar patterns for prior weeks.
Have script that does 50 pings to local name server, and most of
time is 0, with some values from 1% to 10%, but often jumps to
high rates over 80% to 100%. At which point the internet is
useless. All lights on modem are fine, TV, phone, and 4 Linux
machines all will report no internet. Traceroute to 8.8.8.8 still
works, but when no loss takes total of 1.3 seconds
While getting high loss using -n the time goes to 5.6 seconds, and
without -n takes 2 minutes 13 seconds?
Hops change of three test changes from 10, 14, and 13.
Summary of time.
Up Time Hours Days
129:29:28 129.4911 5.40 90.76%
Down Time Hours Days
13:15:54 13.2650 0.55 9.24%
Script plays sound when ping rate over 10%, and reset brings
everything back to normal. But for how long before it returns has
no pattern that I can find. On some cases if not around to power
cycle it, it will start working again, but rare. Usually, only power
cycle fixes it.

Haven't found a way to send software reboot to modem, so only
physical power cycle works. Seems company was bought by
another and info from web site has been useless.
Looked at netstat and nstat info before and after outages, but don't
see anything from the linux side that shows what issue is.

Fedora 38: Video ATI Radeon HD 6400M/7400M low resolution after
update from Fedora 35
by Dario Lesca
On my notebook[1] I have update from Fedora 35 to Fedora 37, then to
Fedora 38.
Now If I start with last Fedora 38 kernel (6.3.11-200.fc38.x86_64) the
system start without fully graphical boot and monitor is set to low
resolution 1024x768 (4:3) instead of the usual 1366x768 (16:9).
If I start with old kerner 5.17.5-200.fc35.x86_64 all work fine.
I have check the initrd of two kernel and I have noticed that into
kernel 6.X the radeon (and also amdgpu) firmware is missing
[root@fedora initrd-5]# lsinitrd -k 5.17.5-200.fc35.x86_64|grep radeon

[root@fedora initrd-5]# ls ../initrd-*/usr/lib/firmware/
../initrd-5/usr/lib/firmware/:

How to I can resolve my problem?
Why the firmware is missing?
