Firewall and RPC Setup for NFS
by Jonathan Ryshpan
Setting up to use NFS I've found that RPC doesn't work; it's blocked by
the firewall. I surmise that RPC is one of the services listed in
System->Administration->Firewall under the "Trusted Services" tab. But
which one? If my surmise is not correct, how do I enable RPC service
without turning off the firewall?
The OS is Fedora-10 with all updates running on an x86_64 system. In
"Trusted Services" NFS4 is enabled.
Thanks - jon

F10 won't bootup. Stalls at startx, and gdm
by Nigel Henry
F10 was booting up fine yesterday, and I had been trying to get Hydrogen
working so that it didn't crash the desktop when I tried to start it. Got
that problem resolved, and had rebooted a few times during getting the
Hydrogen problem resolved.
Today I try to bootup F10 and it stalls when trying to startx, and gdm. The
monitor is just clicking off, and on. No text, no nothing.
Next I bootup, appending the kernel line in grub to boot into runlevel 3,
which gets me into runlevel 3. I login with username, and password, then su
to root. Then I type gdm, and gdm opens, and I can login to KDE with no
problems.
There are some 300MB of updates waiting for my F10, but this problem has
arrived before installing any of them.
With most of the installs on this Asus M2N-X Plus mobo, I have to append the
kernel line in grub with acpi-off, otherwise the bootup hangs when starting
X. Everything is locked up. With acpi=off F10 has been booting ok up to to
ysterday. Quite why I'm now seeing this problem with F10 is to say the least,
a bit bizarre.
Anyone have any ideas as how to resolve the problem, apart from re-installing
F10?
Nigel.

RAID1 /dev/md4 lost one disk partion /dev/sdb4 after reboot, WHY??
by L
Hi
I have RAID1 system, the partition /dev/md4 is in raid1 with
/dev/sda4 /dev/sdb4. In order to check /dev/sdb4 I remove it from
/dev/md4
mdadm /dev/dm4 --fial /dev/sdb4 --remove /dev/sdb4
after checked it, I added it again
mdadm /dev/md4 --add /dev/sdb4
The system did sync md4, this lasted ~ 6 hours. however, after reboot,
/proc/mdstat shows /dev/md4 has one disk /dev/sda4 active.
I have no choice, but add it again. the system do sync once again.
apparent something is not right.
How to let system hold both partitions /dev/sda4 and /dev/sdb4 for
/dev/md4 after reboot?
thanks

Fedora-10/KDE losing keyboard connection
by Timothy Murphy
I notice that my Thinkpad T43 has started getting
into a rather strange state every other day, or thereabouts,
where pressing keys seems to have no effect (even Ctrl-Alt-Del),
although the mouse still moves the cursor.
I was surprised to find the other day
that I could still contact the laptop from another machine,
and could even ssh into it, and re-boot it remotely.
(I should have looked to see what was going on, but forgot.)
I wonder if this is a common phenomenon,
and if so if there is any simple way of getting the machine
out of this state?
(I suspect it may have something to do with suspend-to-RAM,
which started working brilliantly a month or so ago,
I think more or less when this phenomenon started.)

Sound pops
by Ranbir
Hi Everyone,
I have fully updated F10 system running on an Asus P5Q-E motherboard.
Yesterday while listening to some mp3s, I heard snaps, pops, and
crackles (rice krispies are tasty!). At first I thought it was maybe a
poorly encoded mp3, but listening to many other mp3s didn't remove the
issue.
Has anyone else experienced this recently? I remember reading here
quite a while ago about similar issues. I believe at that time it was a
problem with pulseaudio. Maybe the bug is back. :: shrugs ::
Any input would be appreciated!
Regards,
Ranbir

odd bind problem
by Mark Haney
I've got a newly installed F10 box that is running BIND as a slave.
I've been seeing something really odd, though. About every 6 or 7 days
DNS recursion fails. There are no real error messages, but suddenly I
can query any record we are SOA for (we host a couple dozen zones for
customers) but we can't query, say www.google.com from that server. We
get a SERVFAIL.
At first I thought it was due to a package update, but this has happened
3 times in 3 weeks and is unacceptable for a slave server. Any idea
where to begin debugging this problem? Anyone else seen this?

Sadly, man lsmod only tells me it produces a "nice layout", without
telling me how to interpret the colums.... I assume the first number
is its process id,the second one how many modules it either calls (the
ones listed) or is called by -- and the ones with "0" in this place are
not active/ends of chains????? -- and the lower the pid, the earlier the
proces/module started?

Just tried selecting "default" for both & get "problems with audio
capture" or "problems with audio playback"
Selecting "pulse" for both gives unintelligible sound
Selecting "si7012(hw:si7102:0) for both, works.

do these diagnostics tell me my MMC card is toast?
by Robert P. J. Day
inserting a rocketfish 2g SD card into the reader in my fedora 9
laptop generates buckets of:
Mar 28 15:16:50 localhost kernel: end_request: I/O error, dev mmcblk0, sector 8

... etc etc ...
should i just assume this card is toast and get another one? or
might there be another reason for the above?

Yes, somehow, I had a .repo for free-updates, with enabled=0, used gedit

Thanks, Kevin. If I remember correctly, in some replies to other
questions about sound devices, you wrote something about "Alsa being on
top of PA" (or vice versa!) - I also read that various programs are
"Front end" or Backend" to something else.....
Question 1 - which way is "front" & "back" ie nearer Hardware or nearer
User?
Question 2 - is there a way for naive users (like me!) to find out what
sequence of modules/software/gizmos is actually involved in say, getting
the noise from my CD/DVD/AC97 to the speakers?
Question 3 - does having ALSA mixer. KMix, Pulseaudio Volume control
open at the same time cause any problem?
Question 4 - when I open PA Manager, what is meant by "Sound Server"
(only servers I ever met were either in a restaurant or a big box in a
computer room for supplying things to networked computers - & I don't
have either here in my workroom!)
Question 5 - in the Skype example above, how can I find out what the 4
SiS variants represent?
Question 6 - (maybe the wrong place to ask this one...) KMix handbook
says I should see 3 tabs, one of which is switches, and "leds" to show
which controls are active.... I only have 1 tab & no leds; normal in
KDE4? (KMix Version 3.5 Using KDE 4.2.1 (KDE 4.2.1) from "About KMix")
Many many thanks to you & Rex for helping me through this minefield of
confusion!
(Is there a "for Dummies" guide to all these things somewhere on the Web?)
Thanks
Dave
