Soundblaster
by Antonio Montagnani
I have two similar PC (old Pentium but workin fine)
In Pc no.1 I upgraded from RH8 to Fedora and it went fine: Soundblaster
is working fine
In Pc no.2 I made a fresh installation but in redhat-sound-config Fedora
doesn't see any card, that was working on Redhat 9 after soundconfig...
Where is the trick?? I assume that my Sounblaster is an old 16...but
fine on a router/firewall.
Tnx

Tablet hardware
by Florian Weimer
Is there any tablet-like hardware which is well-supported by Fedora 20
and later? Something with a high-resolution display?
I don't need 3D acceleration beyond what's needed to run a typical
desktop environment, but I'd like to have lots of RAM, a bit of CPU
power (perhaps even a current Core i7) and an SSD with decent read
speed.

SATA II causes system freeze
by David A. De Graaf
For several months I've been trying to track down the cause of
frequent system freezes on a machine I built in Dec. '13.
The frequency of freezes has gradually increased from never to several
times a day.
The solution is so improbable that I wonder if I am hallucinating.
I simply moved the SATA cable from a SATA 2 to a SATA 3 socket on the
motherboard.
There are two hard drives:
/dev/sdb - the primary ATA disk with several partitions that constitute
the working Fedora 20 system. This is a Western Digital WD 2500BB-00G
250 GB with old-style 40pin ATA ribbon cable to the ATA socket on
the mobo.
/dev/sda - the secondary SATA disk, a 1 TB Western Digital WD10EACS-00D.
This is used solely to save a backup image of another machine, updated by
rsync every night at 10:30 PM. It has a SATA connector and, according
to the newegg spec sheet, runs at 3.0Gb/s, which is SATA II. The SATA
III spec runs at 6.0Gb/s. Except for the nightly backup, this disk is
never used, or as Mr. James Clapper might say, never used "wittingly".
The imponderable questions are:
- why would plugging a SATA II disk into a SATA II socket produce
random freezes?
- why would plugging that SATA II disk into a SATA III socket NOT
produce freezes and work well?
- Is this behaviour indicative of defective SATA mobo sockets,
defective ata software, defective hard drive implementation?
Originally, I had used a Gigabyte 78MT-USB3 mobo, but replaced it with
an ASRock 960M/U3S3 FX mobo in a futile attempt to fix the problem.
For several months the original Gigabyte mobo worked fine - and then the
freezes began. These may be the only two available mobo's with both
the AM3+ cpu socket and an ATA disk socket. The Gigabyte mobo has only
SATA II sockets - 6 of them, while the ASRock has 2 SATA III and 4 SATA
II sockets.
For completeness, I've tested all four SATA II sockets. All cause system
freezes, one as quickly as 12 minutes, another as long as 20:27 hh:mm.
In contrast, use of either of the SATA III sockets yield a stable system.
When the system freezes, if X is lit (not screen-saved) the LCD
monitor looks as if it had been hit a sharp blow on the right edge so
that all the pixels have been shaken loose. All vertical lines are
shimmering off to the right or left in quarter inch blocks. The image
is still recognizable and almost readable. The NumLock key toggles
its LED, but not the ShiftLock or ScrollLock. No other keys are alive
including Alt-Fn-N, CTL-ALT-BS or CTL-ALT-Del. There's no mouse
action. The ethernet card LEDs blink, but pinging from another
machine fails. Only the Reset button, or the Power button, work.
Before stumbling onto the SATA II -> SATA III solution, here are some
things I tried, that failed:
- Replaced the motherboard (as noted).
- Added a second 4GB memory stick
- Ran memtest86 for a day and a half without a single error
- Watched the cpu temperatures and saw only normal values
- Cleaned and reseated the cpu and applied new thermal grease
- Disabled skype
- Unplugged a USB camera and microphone
- Removed a USB Logitech wireless kbd/mouse; replaced with wired ones
- Converted the ATA primary disk to SATA via an adapter. Although not
tested extensively, when plugged into a SATA II socket it ran OK.
So, wizards, has any of you experienced a system freeze such as mine?
Can you attribute it to connecting a SATA II hard drive to a SATA II
socket?

rc.local not start at the boot
by Angelo Moreschini
I would say that this thread is the continuation of a my preceding thread :
“selecting some kind of files using the resync command”
There I got help in order to make the backup of some my critical files.
Now I am able to backing up these files using a shell script from the line
command.
But I would like also that this backup runs automatically when the computer
boots.
I know that this task is performed by the rc.local file, in Linux.
Ed Greshko gave me a link about an announcement of Fedora concerning
rc.local ....
there is wrote :
- - - - - - - - - -
The /etc/rc.d/rc.local local customization script is no longer included by
default. Administrators who need this functionality merely have to create
this file, make it executable, and it will run on boot.
- - - - - - - - - -
After I read this announcement, I create the the file rc.local and I made
it executable:
[angelo_dev@zorro rc.d]$ ls -l /etc/rc.d/rc.local
-rwxr-xr-x. 1 root root 1262 Oct 27 12:18 /etc/rc.d/rc.local
But, doing some tests, I saw that the scripts stored inside rc.local not
run at boot, ...on my computer.
I would like to have some advice concerning the way to manage tests, in
order to understand because the content of rc.local is not executed at the
start... and to obtain that scripts run at the boot

Closing port 631 from other computers
by Jarmo Hurri
Greetings.
After the recent security incidents I am trying to increase the security
of my computer by closing unnecessary ports from outside world.
The only listening port in my system right now is port 631 (ipp), as
"lsof -i | grep -i listen" reports:
************************************************************************
cupsd 2349 root 10u IPv4 37790 0t0 TCP *:ipp (LISTEN)
cupsd 2349 root 11u IPv6 37791 0t0 TCP *:ipp (LISTEN)
************************************************************************
I tried disabling cups services, but then printing stopped working.
So ok, I need a connection from my computer to port 631 for
printing. But that port should be closed from all other computers. At
the moment it is open to the outside world (10.13.3.247 is the address
of my computer in LAN):
************************************************************************
[jarmo@localhost ~]$ nmap -sT 10.13.3.247
Nmap scan report for 10.13.3.247
Not shown: 999 closed ports
PORT STATE SERVICE
631/tcp open ipp
************************************************************************
I tried to close the port using firewalld. But the port does not seem to
be open, and firewall can not close it. I can freely take a telnet
connection to the port. The first commands show that firewalld is
running and iptables is not.
************************************************************************
[jarmo@localhost ~]$ systemctl status firewalld.service

Trying 10.13.3.247...
Connected to 10.13.3.247.
Escape character is '^]'.
************************************************************************
So I must be doing something wrong. My questions are:
1. Have I diagnosed the situation correctly? Is port 631 really open to
the outside world?
2. If port 631 is open, why can I not close it using firewalld?
3. What is the best way to deny connections to the port from any other
computer than that of my own? Is it the approach I have taken now?
Thank you for all your help in advance.

Where is a Camera Mount Point?
by Stephen Morris
I have plugged a digital camera into my usb port and mounted it using
the popup displayed from the auto detect via konqueror (this annoys me
as well). When konqueror is launched it displays the contents via
Camera:/ which is okay, but subsequently I can't find any entries under
/run that represent the camera. I assumed there would be a mount point
under /run like there is for a usb flash disk. Given that there appears
to not be a mount point under /run, where is it mounted in Fedora 20, so
that I can point dolphin (which is what should be launched from the
'Open with File Manager' prompt, not Konqueror) at the mount point
rather than having to manually type Camera:/ into the address bar.
regards,
Steve

"Input out of Range"
by Beartooth
I normally run three or four computers behind a 4-way KVM switch;
one of them is an old Dell PowerEdge SC1420, which began life as a
server, configured with RAID of some sort. It has long since been re-
purposed and re-configured, and is now an ordinary old PC. I ran CentOS 6
on it for years, but recently installed F 20 instead.
When I boot it, the HP w2207h widescreen flat panel monitor gives
me a message saying "Input out of Range" and tells me to reset to
1680x1050. I can ssh in -- but what little I recall of such efforts years
ago, when the monitor was new, is no help; and I can't seem to find the
setting I need to change.
When I've had this problem in recent years, I could shut
everything down, swap cables around like a crazed beaver, ending up with
the Dell, and only the Dell, connected to the peripherals -- directly
connected, without the KVM switch between -- and simply reboot.
Either CentOS or earlier releases of Fedora would find the
monitor, change the setting, and be fine. That now fails.
What file do I need to get into to tell the machine 1680x1050??
When I do once get into that file, do I simply find lines that
look similar to 1680x1050 and change them? Or is something fancier going
on??

gnutls, openssl and compiling mutt
by AV
Does it make any difference if mutt is compiled with '--with-gnutls'
enabled or with '--with-openssl' enabled.
Mutt (Fed20/21/Rawhide package) shows that '--with-gnutls' is used.
I ask because I have no problem connecting to my ISP Ziggo
with mutt when using Fedora.
With the following in .muttrc:
set ssl_starttls = yes
set smtp_url = "smtp://volovics@ziggo.nl@smtp.ziggo.nl:587
the TLS connection is established successfully and I am asked to
accept the certificate. Everything works OK from then on.
But this does not work on a MacBook Pro with OsX Yosemite.
I use the Homebrew mutt. This mutt is compiled with '--with-openssl',
linked to 'openssl-1.0.1j'.
Using the same .muttrc file I use in fedora the TLS connection
'aborts' and I get the error message:
"SSL failed, I/O error. Could not negotiate TLS connection".
The openssl-1.0.1j from Homebrew seems to be the same as in
Fedora Rawhide though I have not checked all the patches.
(Of course mutt in Fedora is compiled with gcc and the Homebrew
mutt with LLVM Clang. Ziggo seems to be using TLSv1)

A Linux for the totally maintenance free
by JD
Have a friend who wants to try getting away from windows, which,
in spite of all the AV software the vendor had installed on her
windows 7, it was plagued by viruses that rendered it unusable.
So, since she is not technically savvy, I was thinking of finding a linux
distro that is practically self maintaining, as she has zero tech savvy for
doing things like updates, configurations, fililing abrt reports, .....etc.
Any ideas what linux to use for such a person?
Thanx.
