Unable to connect to a multicast session in Fedora 9 with realtek RTL8111/8168B
by Jon Dufresne
Hi,
I have been debugging this issue for quite some time and think I have
reproducible evidence that localizes this to the hardware.
I have a single nic, lspci lists it as:
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
I want to connect to a multicast session using my Fedora 9. I have
successfully connected to the same multicast session using other PCs,
some running Fedora 9, some running other distos, and some running
Windows. If I put a 3com nic into my box, I am able to successfully
connect to the multicast session using my box.
I broke this down to a very simple program. I now just do the bare
minimum to connect to the stream. I am going to attach the c file of
the program. When I run this on a working computer, it gets through
the loop grabbing data off the multicast session. When I run this on
my box with the realtek chip, the program block on the call recvfrom()
forever.
I am left to conclude this is a bug in the realtek driver that is
preventing proper joining of a multicast session.
Any idea about how to resolve this or test it further?
Thanks,
Jon

mount relatime option / Ext3-fs: Unrecognized mount option ...
by Ryan Sawhill

Hey Gary. I can't believe you're the only other person that has posted
something about this issue. I ran into it a few days ago when I first
updated to 2.6.26.6-79.fc9.i686. I guess we're the only people who use
the relatime option that have updated so far. Anyway. Prime example of
why one should never remove an old kernel before testing a new one....
For those that didn't quite understand what Gary's saying, this latest
kernel doesn't appear to have support for relatime, and so the system
chokes right after GRUB passes control to the kernel and it tries to
mount / read-only. I'm no dev though--haven't looked at the source.

desktop cpuspeed
by Hiisi
Hei, List!
I'm running Fedora 7 on an old computer. It's Celeron 510 MHz with 256
MB RAM. I use it in a scientific laboratory for temperature controlling.
(There's a simple program that sets the temperature of heater in polymer
films orientation machine) Since it's the only computer in the
laboratory I'm interested in speed it up for simple tasks of text
editing and WEB browsing. I would like to do it not so slow. Looking for
a bit more RAM for it but useless yet - can't find DIM memory anywhere.
What is possible to do, I suppose, is to speed up its CPU frequency. I
could not find this option in BIOS. There's some record about processor
but I can't change there anything. Then I was trying to speed it up
using cpuspeed program. But useless. I've seen somewhere while googling
'cpuspeed usage' that it utility is only for laptops. So, here's my
question: how to speed up my CPU?
Thanks in advance.

Fedora 9 Boot Problem
by Jack Lauman
I've got an ASUS M3N78-EMH HDMI motherboard with 2 Gb RAM & AMD 5600 X2
proc.
There are (2) Seagate ST350032NS (500 GB SATA drives) configure in the
BIOS for a RAID1. The OS is RedHat Fedora 9.
Following successful installation, it fails to boot. The grub boot
loader displays correctly but immediately goes into POST and reboots as
soon as the OS begins to load. There are no errors displayed.
If I use the recovery CD, I can mount the sysimage and run yum update
and install software successfully. I cannot get this machine to boot on
it's own without following this procedure.
Any assistance in resolving this would be greatly appreciated.
Thanks

How do I do a selective, recursive copy ? Bash script ?
by linux guy
I have a huge multi level directory of legally ripped music. I ripped
my CDs as flac and mp3.
How do I easily copy just the mp3 files onto another drive ? Ie, ignore
the flac files and copy only the mp3 files ? I want to keep the
directory structure intact.
The main directory is Music. In Music is BandA, BandB, BandC, etc.
Inside BandA is Record1, Record2, Record3, etc.
Inside Record 1 is song1.flac, song1.mp3, song2.flac, song2.mp3, etc.
I want to preserve the directory structure. I feel a script coming on.
Am I right ?
Thanks

selinux stops nfs?
by William John Murray
Hello all,
I am trying to persuade an F9 box to export an filesystem
with nfs. It seems to be unwilling:
Oct 27 10:49:41 RAL-161-1-14 rpcbind: rpcbind terminating on signal.
Restart with "rpcbind -w"
Oct 27 10:49:41 RAL-161-1-14 setroubleshoot: SELinux is preventing the
rpcbind from using potentially mislabeled files
(/home/murray/.xsession-errors). For complete SELinux messages. run
sealert -l 14ad5007-8011-4b44-91e9-a4d0932e2f5e
Oct 27 10:49:42 RAL-161-1-14 mountd[20260]: Caught signal 15,
un-registering and exiting.
Oct 27 10:49:42 RAL-161-1-14 kernel: nfsd: last server has exited
Now SElinux is in permissive mode. But the error claims that
SELinux is preventing the rpcbind from using potentially mislabeled
files
(/home/murray/.xsession-errors).
Now this seems odd - this file is not one I am trying to export. And I
have definitely got 'permissive' set. But I do the following anyway:
restorecon -v '/home/murray/.xsession-errors'
And restarting nfs gives the same error all over again.
What am I doing wrong?
Thank you,
Bill

Problems after compile kernel 2.6.27 on fedora9
by Bob
Hi, All
I have problems after compile kernel 2.6.27 on fedora9.
The System can boot successfully except there is no background picture at the boot menu which has the show details button.
And after boot, i can see the icons on the Desktop but all of the icon's name can't display.
So as the console, I can exec commands, but couldn't see the result display.
Is someone can give some advise?
Thanks a lot!

Thank you so much for the link, I download the file
"hybrid-portsrc-x86_32_5_10_27_6.tar.gz" and the readme files, the
direction are written for people that are familiar with Linux. I got
stuck on step 5 "make -C /lib/modules/<2.6.xx.xx>/build M='pwd'" I
replaced the contents of <2.6.xx.xx> with "2.6.26.6-79.fc9.i686" which
is the directory I found in my computer in the directory there is a file
"build" and yet the result No such file or directory I try also as root,
same problem. Any help is greatly appreciate. Vinny

VDQ : rhgb, plymouth -- and mkinitrd
by Beartooth
It seems rhgb (which I have always detested, and routinely
removed from all machines) is to be replaced by plymouth -- which hides
not only the boot messages I want to watch, but grub, too. (That seems
insane for anyone who has multi-boot machines; I must have misread a web
page, or otherwise be confused somehow ....)
So in F10B, "yum remove rhgb" turns into a command that removes
plymouth -- and takes mkinitrd along with it.
So do ordinary users need mkinitrd?? Is it OK to let yum go ahead
and take it away?
To the best of my knowledge and belief, I've never once used it,
in all the years since RH7; but I could make a long list of things I've
tried removing, only to be warned that something I can't do without
depends on them. Is mkinitrd one of those? Or not? How do I tell??
