xsane doesn't work
by Angelo Moreschini
recently xsane stopped to work on my computer...
I don't remember exactly what i did when this happened (perhaps I made
something of wrong on the panel configuration setting ??).
They are several days that I manage to fix this problem.Actually I get the
error :
"xsane error during device I/O failed to open device hpaio:/usb/Deskjet..."
I get this error message after I modified the file /etc/sane.d/hp.conf
with the purpose to add inside it the exact manufacture name of my scanner
(Hewlett-Packard ID 03f0:ac11 ) .
Before I made this, I got other kind of error messages , as
"failed to obtain value of option source"
and
"failed to start scanner : invalid argument"
I know this is a common problem , I followed this link to try to work
around :
https://cromwell-intl.com/open-source/xsane-invalid-argument.html. till
now without success.
here some lines of error that I got from juornalctl

need iptables.conf syntax
by ToddAndMargo
I am told elsewhere that this is not the proper syntax:
/etc/modprobe.d/iptables.conf add
nf_conntrack_ftp ports=21
Anyone know what the right syntax is?
Many thanks,

I need iptables ftp nat help
by ToddAndMargo
Hi All,
My iptables firewall ported from RHEL won't connect to ftp sites
and throws this error (written by me years ago):
WARNING: active FTP rules have been selected but one or
more necessary modules have not been detected
In /etc/sysconfig/iptables-config, you must add ip_nat_ftp
and ip_conntrack_ftp to IPTABLES_MODULES. Delimiter is a
space. For example:
IPTABLES_MODULES=ip_nat_ftp ip_conntrack_ftp
To load changes, use:
# /etc/rc.d/init.d/iptables restart
# systemctl restart iptables
To check if modules are loaded, use
lsmod
1) is Fedora doing FTP differently in iptables?
2) where do I find
ip_nat_ftp
ip_conntrack_ftp
now a days?
Many thanks,
-T

F28 Parole needs H.264 (High Profile) Decoder
by Robert Moskowitz
I have an iPhone .mov quick time video I need to play for my wife. I get
this message from Parole. When I click on install, nothing seems to happen.
How do I get this decoder installed?
Meanwhile, VLC will play the audio, but the video stays on the first
frame. What's with that?
Or maybe some other app is better?
thanks

auto-kill process using too much memory
by Frédéric
Hi,
It happens sometimes that someone launches a process that uses too
much memory. Then the computer starts swapping leaving the computer
completely out of use. When the swap is full (I guess), the process is
automatically killed and we can work again. But this can last 10-15
minutes.
Would it be possible to kill any process using more than some LIMIT
memory? The aim being to kill it before it starts swapping.
Note that I am using F27 for now.
Thanks in advance,
F
