Fedora 11 install issue
by Kevin Kempter
Hi all;
I downloaded the fedora 11 x86_64 DVD iso image and burned it to a DVD with
k3b.
Now when I start the laptop with the DVD in the drive , the dvd spins up, and
I see this on the screen:
ISOLINUX 3.75 2009-04-16 ETCD Copyright (c) 1994-2000 H. Peter Anvin et al
Then it just hangs...
Thoughts?
Thanks in advance

I didn't understand initially what "pass by name means". Probably had to
look more careful at the program.
Doesn't matter any more. I need to do a statement: this thread is closed
from now. Ones more: thanks everybody for your responses!

You're right. And the person, who needs to verify all this is me. I just
was trying to do it easy. Now I understand - it's impossible. Need to
write the whole program from scratch. By the way, I also have to use
another algorithm. The initial procedure builds quintic natural spline.
Semi-local smoothing spline would suit better to my task. But that's too
more as for this list, as for this off-topic thread...

This looks like a redirection of stdout to the log file. You can add this rule using
# grep polkit-read-aut /var/log/audit/audit.log | audit2allow -M mypolkit
# semodule -i mypolkit.pp
I believe this is actually a bug in xdm. in that it should be passing append privs for its log versus write.
If a relabel caused you to loose labels, then you need to add the labels via semanage fcontext instead of just executing a chcon.
For example, if I had web content under /myweb
# semanage fcontext -a -t httpd_sys_content_t '/myweb(/.*)?'
# restorecon -R -v /myweb
Would tell the SELinux system about my alternative labeling.
A blog I wrote about similar stuff.

I use cached imap on kmail with good results. It is fast and since the
messages are also stored locally it is quite fast.
The only precaution worth of note is not to subscribe the "All Mail" folder
for gmail accounts.

No the mailer didn't "eat it," but I haven't figured how to implement
it. After some experimenting I have to admit I need an example. I am
eager to see it work though.

Hi,
I followed the instructions here for installing Pulse Audio,
(http://forums.fedoraforum.org/showthread.php?t=206868) on my F10
machine, (an F9 upgrade). I did this as I thought the system upgrades
would do this eventually anyway and was interested. However it's just
just caused me grief.
Does anyone have any instructions on how to remove this completely from
my system, that they've successfully used? It's become slow, hard-locks,
sound skips or just stops.

Hi guys,
I'm trying to create an script to verify some databases and their
privileges.
I have all of them in some files with the following format:
server1
server2
server3
server4
Being all of them MySQL servers and the first one the master and the rest of
the just the slaves.
I only want to check the privileges in the slaves and I've created the
following statement:
for i in `cat file1_cluster`; do echo -n $i: && mysql -h$i -uroot -pwhatever
-e"show grants for 'user'@'10.10.%.%';" | grep -i "REPLICATION CLIENT" | wc
-l ; done > /tmp/privs
Keep in mind I just want to know the slaves which doesn't have the
REPLICATION CLIENT privileges, just that.
So that will write in /tmp/privs something like:
server1:0
server2:1
server3:0
Being the value 0 a machine which doesn't have REPLICATION CLIENT privilege
and 1 being the value which mean it does.
The thing is, how can I do the "for" loop to avoid reading the first line of
the file: file1_cluster, file2_cluster etc...cause the master will never
have replication client privileges.
After reading the /tmp/privs with another for, I will use cut -d ":" -f to
look for values distinct from 0 and do a mail -s to the admins.
Any help will be more than appreciated.
Thanks a lot

Camera/F-spot problems
by Steve Blackwell
It's been a while and several versions of Fedora since I tried this
but F-spot used to start automatically when I plugged my camera in to
a USB port. Now it doesn't but I see the appropriate USB messages in the
system log that show the device is recognized correctly.
What does happen is that after a minute or so I see a camera icon appear
on the desktop and I can click on the icon and a Nautilus window opens
with a message at the top saying this media contains digital photos and
a button that says "Open F-spot Photo Manager". F-spot does not open
when I click on this button and there are no system messages.
I can open F-spot manually from the Applications menu but it does not
know that a camera is attached to the computer and I don't see a way to
tell it where to find the camera.
In the end this is just inconvenient because I can get to the picture
through the Nautilus window but does anyone else have similar problems
and/or any solutions?

First of all, thanks everybody for your responses.
Here's a fragment of the initial code:
PROCEDURE QUINEQ(INTEGER VALUE N1,N2; REAL ARRAY Y,B,C,D,E,F(*));
IF N2>N1+1 THEN
BEGIN
INTEGER N;
REAL P,Q,R,S,T,U,V;
N:=N2-3; P:=Q:=R:=S:=T:=0.0;
FOR I:=N1 STEP 1 UNTIL N DO
BEGIN
U:=P*R; B(I):=1.0/(66.0-U*R-Q);
C(I):=R:=26.0-U;
D(I):=Y(I+3)-3.0*(Y(I+2)-Y(I+1))-Y(I)-U*S-Q*T;
Q:=P; P:=B(I); T:=S; S:=D(I)
END I;
D(N+1):=N(N+2):=0.0;
And quotation from paper (year of publication: 1976), that describes the
algorithm: "These procedures have been tested in Algol 60 on the
Telefunken TR-440 computer
at the Leibniz-Rechenzentrum of the Bavarian Academy of Sciences,
Munich, and
in Algol W on the I B M 360/67 at the Stanford Center for Information

I had little problem with modification of it. I just auto-replaced

change by hand FOR and IF-constructions, that is:

F11: Unable to print to HP LaserJet 4250
by Marco Guazzone
Dear all,
Every time I try to print to an HP LaserJet 4250 printer, the result
is the following:
* CUPS says the job has been successfully printed (e.g., status "completed")
* instead, the printer does not print anything, it blocks and shows a
"Service Error" message; the only way to restore is to power it off
and on.
Note: With F10 the printer worked perfectly.
Moreover, if I try to print to another HP printer (HP LaserJet 8000)
I have NO problem.
Here below are some details:
