Re: Alpine paragraph justification failing

[D. Hugh Redelmeier]

| From: Beartooth 
| 
|   Many times, when I hit ^J amid text in compose mode, it merely

| 
|   This is with Alpine 2.0 under Fedora 11; I haven't yet managed to

There is a slight chance that this is due to the screen not matching
what the buffer contains.

Here's how you might be able to tell:

- type control-Z to suspend (assuming your settings allow you to do
  this)

- type the shell command "clear" to clear the screen

- type the shell command "fg" to get back to alpine

Is the text still a mess?  The same mess?  If so, the buffer and the
screen do match.

If not, you might have a curses problem (curses is the library that
handles "full screen" manipulations of text-based terminals).

Historically Test and General Availability releases happen at 10:00am

daylight savings in the United States.

 so how about we not spend the next several hours playing "where's

As has been pointed out, it's rarely necessary.  There's one area where
I a graphical root user is useful, mass file managing where you can't
use wild cards to do the job.  But you don't need to log in graphically
as root to do these things.  Find a decent file manager, not Nautilus,
then just start it off from the command line.

Yes, I've had ones stall and never recover.  It might be because the

Yes, but with caution.  There are some services that I'd be fairly
confident in using, but I'd be extremely hesitant about giving credit
card details to just any site.

I'd look for a third party to go in the middle.  e.g. Put money into
PayPal (if you trust them, and they can accept PayPal), then use PayPal
to pay the other site.

Or do a direct bank transfer, where all the other person gets is money
sent to them under your control.  They've no way to raid more off you.

Some credit card companies offer one-time features, where you have a
single use credit feature, a bit like gift cards in shops.  You put
money into the single-use credit, the right amount, then use that with
the purchase.

Best advice:  Don't ask *us* about this, contact your bank, or credit
card supplier, and see what they advise and can offer you.

Just to throw some other ideas into the ring, you could clone the
installed drive over to the second one.  Though, bear in mind that if
you're going to use this second drive to run Fedora on another computer,
there may be significant enough hardware differences between this
computer and that computer, that you need to do the install on the
computer it will run on.  That, or tweak it about.

You could take away / comment out the "hiddenmenu" line.  That will
remove the hop, skip, and a jump, approach down to being just one page.
Though that page will be the menu of choices in a box, with a graphic
background.  You can change the graphic, if you want to.

run anaconda to install to second hard drive

[idwsh6b02]

I'm running F11 and I'd like to run anaconda to install another
instance of F11 to a second (blank) hard drive in my system. I'd like
to do it without rebooting. The second drive is removable.

What's the magic?

Just running anaconda spits out:

Code:

OSError: [Errno 2] No such file or directory: '/mnt/runtime/usr/sbin'

So it seems I have to do some prep work to get things "ready" for
anaconda.

Re: minor problems with Audio CD fix from Bug 514213

[Paul Allen Newell]

I am pinging this message out again as I haven't heard anything. I want

in getting the necessary info to submit a bug.


Thanks in advance,
Paul

I just logged two more bugs related to a couple things that didn't 
happen with it.


Bug #537740: if one is using a CD-ROM instead of DVD drive, the 
icon/drive/mount doesn't get killed but it still doesn't see that 
there is media loaded


Bug #537741: the system still doesn't see that it has a floppy drive 
and loading a floppy does nothing (this works in f9)


I have one more bug to log, but need a bit of help to submit it.

I have a DVD that I can play in my DVD player. If I put it in my f11 
system, it not only kills the icon (and I suspect unmounts the drive 
and all sorts of other stuff), it actually totally kills the drive and 
I cannot eject the disk. The only way to get it out is a reboot and to 
push the button once the reboot has started after the current session 
has died.


I have tried every other DVD I can find and don't get this behavior. I 
think I need to supply info about "what the heck this DVD is", but 
would like some advice about what/how to query to give enough info to 
make a bug submission meaningful. I've got Linux f11 and f9 plus 
Windows XP to do querying.


Thanks in advance,
Paul

The CHECKSUM files in the i386, ppc, and x86_64 torrents are the same as
those for RC4.  The RC4 install ISOs are in fact dated 11/9, although
their CHECKSUM files weren't signed until the 12th.

Re: trying to understand SELinux message

Allow an confined application to write to /root would allow it to do evil stuff 
by replacing /root/.bashrc for example.

And the next time an admin logged in the script would run.  


If you require running X as root then you will need to put SELinux into 
permissive mode.  In F12 we are now preventing users from logging in as root 
from GDM because it is so dangerous from a security point of view.

Imagine running firefox as root and what problems it can cause.

This is a very good explanation of why I should not be logging in and

Good thinking. You definitely do not want to disable SELinux. It is there for 
a good reason, even if one doesn't know the details of what that reason is.
 
  
Yes, I know I should not start X server or login as root ... 



So why did you do it then? Disabled root GUI is also the default for a reason, 
just as SELinux. They are multiple protective layers that try to secure your 
system from any malicious activity, including your own.


  

and that is
not my normal work habit. But I would expect that I should still be able
to do such and not have SELinux bark unless there was something wrong.
It is the "what is wrong" that I am trying to understand and correct.



What is wrong (technically) is you moving files across directories without 
changing their SELinux context appropriately. At least that appears so based 
on the info you provided.


However...

What is wrong (essentially) is precisely logging in as root in a GUI. This is 
disabled by default in Fedora, and SELinux policy assumes you run the default 
configuration. Once you enabled root GUI and started poking around in it, it 
was just a matter of time before SELinux starts yelling at you doing this or 
that wrong. I cannot tell exactly what SELinux is complaining about until you 
provide some setroubleshoot info, but it is definitely because you logged in a 
GUI as root, played around with things and then did something SELinux doesn't 
like. And it will keep happening over and over unless you stop using root GUI.


If you are more familiar with Windows world, this would be like logging in 
with admin privileges, disabling antivirus software and automatic updates, and 
then asking "why does the system keep alerting me that security might be 
compromised?". Well, you compromised it.


So much for understanding.

As for correcting the error, I can advise the following:

1) Find all files that you have been mv-ing as root, and move them back to 
their original location.

2) Stop using root GUI.
3) Learn that mv keeps SELinux labels in contrast to cp which changes them 
appropriately. Understand that this is intentional feature of mv and cp. The 
file and directory labels are displayed by "ll -Z".
4) Whenever you need root access use "su -" to log in as root, or learn to 
configure and use sudo. Use only your normal user account for GUI.
5) For regular system administration you don't even need to use su and sudo, 
because the system should ask you for the root password whenever you start a 
GUI app that needs elevated privileges.
6) If SELinux keeps complaining more, learn how to use setroubleshoot utility 
and post the output here on the list. People will help you correct it all, but 
only after you make sure not to produce any more problems by using root GUI.


HTH.

Best, :-)
Marko

  

Marko:

Appreciate the reply.

The information provided about SELinux context is what I was trying to 
understand. I am sufficiently newbie to not really understand what 
SELinux is doing and, given your info and the post about "SELinux is 
preventing the gdm-session-wor from using potentially mislabeled

files (.dmrc)." make it very obvious what I did to incur the warnings.

I now can backtrack my actions and see what I did wrong. Lesson learned 
regarding SELinux labels.


This upcoming weekend, I will go back and su to root to correct using 
the suggestions you provided.


There is a strong temptation to defend my logging in as root just like a 
child defends an indefensible action. So, to you and everyone who said 
"don't do it", I have no defense. I'm not from a Windows world, I'm 
old-school Unix where the only way some things could be fixed was to su 
to root and it was just easier for big tasks to log in as root. No 
excuse for that now, but old habits die hard. Once again, no defense on 
my part ... I've offered my lame reason just to show its lame.


Thanks,
Paul

Sorry  That wasn't the movie clip.  That was the PBS video you
referenced in:

As I said, it isn't easy or simple.

In order to learn
"tp-live/PBS_CP_General_Audience/cosby-full-revised-CHN.mp4"  you have
to use tcpdump or wireshark to capture the IP packets and then look at
them to find the information.  The a1863/o6 string is also part of the
RTMP protocol that you need to determine.  That info is also in the IP
packets but seems to be the same for all PBS videos.

So, that is what you need to do for PBS.

For BBC, you should investigate get_iplayer or iplayer. 

For CBC, you need to do your own research.

The bottom line is what I said earlier.  Each media provider uses their
own version of middle ware.  So, for each media provider you need to dig
in and figure it out.  I've done that for you for PBS and BBC with the
help of google as well as my own understanding of IP packet capture.

When trying to "download" a file from another computer, scp reports 0

Other download commands (e.g. yum update) work just fine.

I would say it this way..."no simple/easy way to get hold of it".

For example, in data being streamed (but not stored) on your system it
is possible (but not easy) to capture the IP packets and then
reconstruct the data.  Of course you need to know the protocol being
used and how to reassemble the packets.  Then, even if you do that, the
data may have been compressed so you would have to know what compression
algorithm was used to uncompress it (not so hard).  And the data may
have been encrypted with the receiving application being responsible for
decryption.  So, you need to know how to decrypt (not so easy).

That said, I gave you a start for saving those movie clips.  I also can
tell you the key to saving BBC videos is probably an application called
iplayer or get_iplayer.

And it isn't all that amazing at all.  This has been happening for a
long, long time.  Have you ever used vncviewer, run a remote X session?

And think of the simple case of "sftp u...@somehost".  There you have a
data stream between 2 systems...with no easy way to capture the data
stream and reconstruct it.

There's been exactly 1 gcc-induced bug in alpine that I'm aware of, which

Quite possibly your code was wrong.

C89 doesn't require much of floating point.
if(x/11.0==13.7) { ... } would almost certainly be wrong.
There might be compilers and hardware for which

but that wouldn't mean the code wasn't wrong.
if(x< 150.7) { ... } might be good.


It gets more arcane with chained calculations.  Each time you multiply
two numbers together, there is an associated rounding error.  But it is

With difficulty.
One has to live with the fact that floating point
arithmetic is not real number arithmetic.
One will sometimes have to deal with cases too close to call.
Really good code will detect them.
It's not easy.

SCP works one way only

[Konstantin Svist]

For some reason, I can only SCP files off my new NAS, not to it.
I've tried both using it as a server and as a client with same result.

When sending a file to it from another computer, scp reports a certain 
amount transferred (1.9M) and then immediately stalls. The target file 
stays 0-bytes in length.
When trying to "download" a file from another computer, scp reports 0 
bytes transferred.


Other download commands (e.g. yum update) work just fine.

arch: x86_64

P.S. The install in question is F12, but since it's 1 day away from 
release, I'm asking here.

P.S. I'm using Thunderbird, and don't know how to suppress the HTML 
formatting. I appologize.


Its one of those well hidden attributes.

Go to (the book icon) then highlight and select each

You will need to do this for every addressee on your list, unless

Given that I have seen all kinds of effects in C code, but generally
from compilers that are not "ISO standard" what ever that really means
(ISO is not cast in stone by any means either when it comes to almost
all things).

But some things have to work for programs to compile and run across
platforms.

The basic copy function which is in most text books:
*a++=*b++;
for example, but I have seen compilers break this bit of code.
The effects run from:
*++a = *b++
*++a = *++b
*a++ = *++b

I have seen some folks attempt to fix it with parens:
*(a++)=*(b++);  but that is probably predictable, but would mean that
the pointers would have to be set artificially prior to the call to
point one location earlier, and the exit condition would be pointing
after the last character.

Some other interesting artifacts I have come across deals with macro
substitution between debug code and release code, where macros may be
substituted for ease of tracing during the debug phase, but the code in
the macro is subtly different from the code in the routine used for
tracing execution.  Works at Debug but not release, or visa versa
depending on the conditions of the two implementations.

In short, I agree with Rick that you need a book, not just on C, but on
the version

Upcoming IRC Class tomorrow! (2009-11-17)

[Kevin Fenzi]

Greetings. 

This is a regular posting every monday,

scheduled. 

From the Classroom page at:
https://fedoraproject.org/wiki/Classroom
we currently have the following Classes scheduled: 

2009-11-17 14:00 Dan Walsh - Secure Virtualization sVirt

Note that this is in the morning in North America, just before the F12 release.
(Use 'date -u' to see your current time and date in UTC). 

Please see the above page for more information on signing up to teach a
class, providing feedback to the classroom mailing list or other
general information. 

Hope to see lots of folks there!

Incorrect.  C, for example, does not guarantee the order of evaluation
of arithmetic operators of equal precedence in the same statement (in
other words, is something like "a + b + c" evaluated left to right, or
right to left?).  This can have significant effects if some of the
operands have "side effects"

Another example is that a null pointer (or the value "NUL") is not
necessarily zero, only that it is guaranteed to not point at any valid
datum.

C allows quite a bit of leeway to the compiler implementation.



I think I disagree on this one. We jumped from standardization of keywords to
how operators perform. I quote from page 53 of K&R: Table of Precedence and
Associativity of Operators: a + b + c *always* goes from left to right. K&R is
not the standard, but does the standard say otherwise? Lots of things are up
to the compiler writer, but I'd be surprised if this was one of them. Sometime
people worry about things like

a++ + b++ + c++

but even there, the precedence and the associativity are defined. In this case

a++ + b++ + c++

becomes (in psuedo stack code):

a++
b++
c++
a b +
c +

because binary + is lower precedence than ++.

No?


No.  The value of a++ is the original value of a.
Assuming a++ does not change the stack:
a b +
c +
a++
c++
b++

Also allowed:
c b a
b++
+ 
c++

+
a++

I probably should have added "...subject to standard rules of 
arithmetic".  AFAIK, there's no guarantee to the order that any given

operand to an arithmetic operator will be evaluated if they're at the
same level of precedence.  In the examples you give, the binding of "++"
is higher than addition so that's unambiguous. But if a, b or c are, 
say, pointers that depend on the values of one of the others, then side

effects can be dangerous (the classic example of that is "getc(3)").

What I was trying to get across is, while the library is pretty 
standardized (with the exceptions usually called out in the man pages),

there are some things that different compilers will do differently and
one should take reasonable care to make sure to use order enforcing
syntax to make things work properly.

However even that is off the point of this thread.  The C _library_
is documented, but that's because it is the underpinnings of many of
the high-level languages used (C, C++, Fortran and most of the others).
The languages themselves normally aren't.  The perl, python and several
other groups do create man pages for their languages (which can be
massive) and that's a nice thing, but IMHO it's somewhat inappropriate.
If you need to know C, get a book.  Ditto C++ or python or other high-
level language.  Don't rely on man pages.

I'm not even sure I like all the stuff you get with "man bash", but you 
all know that I'm a curmudgeon.  :-)

No.  a++ means:  produce the value of a for use in the expression, then
increment a.
 ++a means:  increment the value of a, then use the incremented
value in the expression.

So, a++ + b++ + c++ produces the value (a+b+c), but the variables a, b,
and c get incremented *after* their values get used in the expression.

For example:

2.
smb://domain/user:pas...@printerurl

Neither worked. Previosly I had a smb:// line that worked.
Are there any other ideas out there. I remember that the previos line requirede

 but it seemed to me that it also needed a printer name.

Incorrect.  C, for example, does not guarantee the order of evaluation

It does in the example given.
Binary + associates left to right.

(a+b)*(b+a) could be ambiguous.
Either sum could be performed first.
If their are side effects, order could matter.

Order could also matter if floating point is involved.
C89 doesn't require much of floating point.
It doesn't even require that the same expression with
the same data produce the same number each time.

The following function could return 1:

int fred(float a, float b)
{
int result=0;
for(int j=0; j< 10; ++j) result+=(1f< a*b);
return result;
}

I would hope not.


Another example is that a null pointer (or the value "NUL") is not
necessarily zero, only that it is guaranteed to not point at any valid
datum.

C allows quite a bit of leeway to the compiler implementation.

ogre is another library that might be of interest. It is used to do 3d

Nope, not found, looking at my fc10 (32bit) this is a symbolic link pointing
to ld-2.10.so in the same directory.  Looking at /lib, thats not there either.

In a 2nd email, you asked for

Here is that listing.

[r...@deneb linux-2.6.31.6-PPS]# head -n 15 .config

So, to me it looks like (at least) one rpm did not load, yet the rpm -qa shows 
them
as having loaded.  

I just went back and did a 
sha256sum Fedora-11-X86_64-DVD.iso
and it gave the correct checksum, 
however when I did
sha256sum /dev/cdrom
to check the DVD, it did NOT give the correct checksum.  
Perhaps I should reburn the DVD ?  Or is this not the correct way to check the 
DVD ?

In any case, any thoughts on my problem will be appreciated.

Fedora includes the mesa graphics library, which is a free
implementation of OpenGL. By itself, the OpenGL library doesn't help
you get an OpenGL rendering context, but there are other libraries
which are helpful for that. I'm also very new to the OpenGL stuff, but
I've use SDL to do that. The SDL reference documentation includes
examples on doing that.

As far as I know, at least the basic SDL graphics stuff should work
just fine anywhere you can expect to get a normal graphical program
running. Basic OpenGL stuff is also doable with just a plain vesa
video driver, but of course it'll be quite slow unless you have
hardware acceleration.

I don't think you need the radeonfb driver for anything SDL related. I
think the SDL framebuffer usually refers to the pixels inside the
window that SDL creates for you.

I had a stream at PBS stutter then stop dead in its tracks 10 minutes
before the end. Sometimes, somewhere else, just changing the screen
size killed the video.

That's a reason why I want to save important videos that I might want
to watch again. The other being that they might someday disappear from
the site.

OTOH, I find The Warning, Inside the Meltdown and Breaking the Bank to
be top of the top class documentaries and I'd like to contribute a few
dollars. But I really don't believe in giving away my credit card
number on the net. I only use my credit card to pay my ISP. I'm old
fashion, I suppose.

Do you people use your credit card on the net?

It's running very stable on mij x86_64 Fedora 11 system, both music 
and video's run smoothly. Somehow however I can't play physical media 
like DVD's and CD's, as XBMC doesn't seem te be aware of them. Could 
be a libcdio-0.18 related problem.


I would recompile a version from SVN. It's not as bad as it sounds ;)

Hello Kevin
I appear to be running the same kernel (2.6.30.9-96.fc11.x86_64)  My processor 
is a single Intel Xeon 2.0Ghz QuadCore.  The following seems to show that this

XBMC for Fedora

[Rolf Fokkens]

Hi!

Several people have contributed to this subject in the past: XBMC for 
fedora. So far however XBMC isn't available in rpmfusion or fedora 
repositories. Is there a specific reason (like licensing) for this?


Anyhow, given the fact that there isn't an XBMC RPM in one of the 
mentioned repositories, I built it myself based on an RPM by Scott 
Harvanek. It's here: http://rolffokkens.dyndns.org/


It's running very stable on mij x86_64 Fedora 11 system, both music and 
video's run smoothly. Somehow however I can't play physical media like 
DVD's and CD's, as XBMC doesn't seem te be aware of them. Could be a 
libcdio-0.18 related problem.


Cheers!

Rolf

P.S. I'm using Thunderbird, and don't know how to suppress the HTML

Incorrect.  C, for example, does not guarantee the order of evaluation
of arithmetic operators of equal precedence in the same statement (in
other words, is something like "a + b + c" evaluated left to right, or 
right to left?).  This can have significant effects if some of the

operands have "side effects"

Another example is that a null pointer (or the value "NUL") is not
necessarily zero, only that it is guaranteed to not point at any valid
datum.

C allows quite a bit of leeway to the compiler implementation.

missing CPUs -- kernel-2.6.30.9-96.fc11.x86_64

[Kevin Abbey]

Hi,

I just updated to the latest kernel in the updates of Fedora 11 and the
system is no longer using the 2 quad-core chips
The system is no longer seen as an SMP system using

On the same system the older kernel works fine:

On identical hardware but different server also running Fedora 11;
this kernel works fine:  2.6.30.9-90.fc11.x86_64


Is  this broken?:  2.6.30.9-96.fc11.x86_64

While a pain to do, I have always had good luck getting the full
capabilities of the projector recognized when I do a cold boot of my
Fedora laptop with the projector connected and powered up.

Paul SELinux policy can not be written in such a way to allow you to run X 
Windows as root.

The problem is too many Applications require rights to write to the homedir and 
we want to treat /root differently then /home.
Allow an confined application to write to /root would allow it to do evil stuff 
by replacing /root/.bashrc for example.

And the next time an admin logged in the script would run.  

If you require running X as root then you will need to put SELinux into 
permissive mode.  In F12 we are now preventing users from logging in as root 
from GDM because it is so dangerous from a security point of view.

Imagine running firefox as root and what problems it can cause.

Warning about possible display issues with F12 upgrade.

[Linuxguy123]

Just a heads up that I know of at least 2 F12 show stoppers (as far as
upgrading goes) wherein the computer screen doesn't display the session
properly.  

https://bugzilla.redhat.com/show_bug.cgi?id=529128

https://bugzilla.redhat.com/show_bug.cgi?id=528188


Both of these cases involve NON proprietary display drivers.

If you Google a bit you might find other cases that involve non
proprietary and proprietary drivers.

Long explanation short, I would run F12 live before I did a blind
upgrade to make sure that the video display is going to operate properly
once you do upgrade.

Hope this helps someone.

Is the plan to put windows back on it? You should be able to pop in a

Hmm...

Build a house. Add locks to all the doors and windows so that the
contents of the house can be kept secure. Then disable the locks and
leave the doors and windows wide open.

Makes *perfect* sense.  :-)

Sorry for the very late followup, but after clean installing F12, I see
that the F12 installer has again switched the active partition from the
Windows partition (/dev/sda1) back to the Linux /boot partition
(/dev/sda2).  I'll have to switch it back again to avoid future problems
with Windows updates.

MAC is very useful for home users that run programs that process data
from untrusted sources. This includes web browsers and mail readers.

Most of the people I know who deal with autocad file submissions from the
outside actually prefer not to accept DWG files because they never quite
feel confident that what appears the other end will match what was saved.

Mind you with DXF having a 600 dpi tiff of the drawing as a check
reference is a good idea as well. I've had funnies between qcad and
autocad where things like linesizes changed mysteriously or extra bits
appeared.

Agreed. Some sites don't even support pausing the stream (i.e. the
stream player pauses but doesn't keep downloading, thus becoming
unwatchable on flaky networks as you say). Some NY Times streams seem to
be like this, though not most of them.

how to start with simple SDL programming?

[Robert P. J. Day]

  having never done any SDL programming before (so be gentle), what
would i need to do to get started in terms of loading framebuffer
support for my first program?

  currently, on this laptop, i have perfectly serviceable video with:

$ lsmod | grep radeon
radeon509536  2
ttm42256  1 radeon
drm_kms_helper 25456  1 radeon
drm   172288  5 radeon,ttm,drm_kms_helper
radeonfb   75128  0
fb_ddc  2464  1 radeonfb
i2c_algo_bit6068  2 radeon,radeonfb
i2c_core   28608  8 
radeon,drm,radeonfb,fb_ddc,i2c_algo_bit,i2c_dev,videodev,i2c_piix4
$

  i also have a "radeonfb" loadable module which i'm assuming i'm
going to need.  or am i?  there's certainly enough simple SDL examples
out there to get started, i just want to make sure i have the
underlying functionality in place for my first sample program to run.
thoughts?  or am i going about this the wrong way?

Where? I don't see it for F12. I also note that the author seems to have
received a DMCA takedown notice, instigated by Adobe.

I've heard about using WINE software and AutoCAD 2008.
Also, I believe AutoCAD 2002 has ran on Linux before fairly well.

I'm no expert on the Linux side, but I keep an open ear since I work
as an AutoCAD developer on Windows.

I had a similar problem once, years ago, with a version of redhat linux when
the memory was faster used up than it was free'd by the paging daemon. I
managed to solve the problem by tweaking some kernel parameter's that
influenced the behavior of the virtual memory system. But I think that now
everything has improved with the current fedora versions, so this problem
has disappeared.

This is utter bullshit. I wonder why nobody edited this out of Wikipedia by 
now...

Yes, in the early days SELinux was rough around the edges here and there, but 
not today. And yes, SELinux does have a learning curve, but by now there are 
plenty of nice GUI tools that help people deal with it without actually having 
to learn the internals, changing the policy manually, etc.

This is FUD, please stop spreading it.

Good thinking. You definitely do not want to disable SELinux. It is there for 
a good reason, even if one doesn't know the details of what that reason is.
 
> Yes, I know I should not start X server or login as root ... 

So why did you do it then? Disabled root GUI is also the default for a reason, 
just as SELinux. They are multiple protective layers that try to secure your 
system from any malicious activity, including your own.

What is wrong (technically) is you moving files across directories without 
changing their SELinux context appropriately. At least that appears so based 
on the info you provided.

However...

What is wrong (essentially) is precisely logging in as root in a GUI. This is 
disabled by default in Fedora, and SELinux policy assumes you run the default 
configuration. Once you enabled root GUI and started poking around in it, it 
was just a matter of time before SELinux starts yelling at you doing this or 
that wrong. I cannot tell exactly what SELinux is complaining about until you 
provide some setroubleshoot info, but it is definitely because you logged in a 
GUI as root, played around with things and then did something SELinux doesn't 
like. And it will keep happening over and over unless you stop using root GUI.

If you are more familiar with Windows world, this would be like logging in 
with admin privileges, disabling antivirus software and automatic updates, and 
then asking "why does the system keep alerting me that security might be 
compromised?". Well, you compromised it.

So much for understanding.

As for correcting the error, I can advise the following:

1) Find all files that you have been mv-ing as root, and move them back to 
their original location.
2) Stop using root GUI.
3) Learn that mv keeps SELinux labels in contrast to cp which changes them 
appropriately. Understand that this is intentional feature of mv and cp. The 
file and directory labels are displayed by "ll -Z".
4) Whenever you need root access use "su -" to log in as root, or learn to 
configure and use sudo. Use only your normal user account for GUI.
5) For regular system administration you don't even need to use su and sudo, 
because the system should ask you for the root password whenever you start a 
GUI app that needs elevated privileges.
6) If SELinux keeps complaining more, learn how to use setroubleshoot utility 
and post the output here on the list. People will help you correct it all, but 
only after you make sure not to produce any more problems by using root GUI.

HTH.

Best, :-)
Marko

Logging as root in X is certainly a bad idea, mainly for security reasons. 
Disabling SELinux is an equally bad idea, also for those same security 
reasons. Why do you advise for one and against the other? It looks 
inconsistent to me.

The fact that OP broke one rule and logged in a GUI as root made the other 
protection layer yell at him about that. And when he asks what is going on, 
your advice is to shut down that other layer. But given that the OP is 
apparently a newbie and is not aware of good security practices, this is quite 
a Bad Idea, since it opens a door for him to break his system even more.

My advice would be to keep SELinux on, and refrain from using X as root. That 
provides good system security (both from others and yourself). 

Best, :-)
Marko

Thanks, Kevin. I have just installed VirtualBox and it works fine and

I've been running selinux on f12(beta+) and things look pretty good.
The default yum-installed policy is starting to shape up nicely, with
virtually no more noise in my /var/log/messages and
/var/log/audit/audit.log files.  (I only see one daily gripe for
asterisk, but that should be cleaned up in the next policy version.)

Until you do something that SELinux would have protected you from...

People do actually do things that need securing, on home computers (do
their banking, etc.).  Just browsing the internet and reading your mail
are the two major points of breakdown on the Windows world, and I'd like
it if that problem doesn't migrate over to Linux, as well.

I can't say that I've had mammoth problems with SELinux.  I've had
occasional glitches, but then the errant program usually gets *fixed* up
quite promptly, so it stops trying to do things that it shouldn't be
doing.  Using very strict SELinux rules on test machines, ones that test
packages before release, could only be a good thing for everybody else.

Of course there are some people who insist that there should be no
restrictions, and that any file should be readable by any person, and
any program able to do whatever it wants.  I tend to think of those
people as clueless, or suspect that they are trying to advocate
something that aids them in hacking other people's computers.

Unfortunately, this is all too common.  I'm not too bothered about
saving most things on the net.  But I get continually snagged by
services that are so lagged that I can't watch them (big long wait,
watch half a second, big long wait, rinse, cycle, repeat).  And the

FYI, I just now successfully downloaded the entire Bill Cosby piece with

"rtmp://203.77.184.132/a1863/o6/tp-live/PBS_CP_General_Audience/cosby-full-revised-CHN.mp4"
-o outfile.mp4

I did this on my CentOS 5 system since rtmpdump didn't compile under
Fedora 11 and I didn't want to debug that.  And I then played it using
mplayer.

All of this I learned by using Google..
