That is a user that already has full root privileges!  That is not a
normal user.  That is a user that already has root.  If they have root
then they are already an administrator on the system and don't need to
break into it.

And what did I specifically say?  I hinted at what would be a wrong
answer.  I said not to give an example using sudo.  Because obviously
root can change the clock.  What did you do?  You gave an example
using sudo to use root to change the clock!  Of course root can change
the clock.  Not an interesting case.

Did you also know that users who have the root password can use su to
become root too?  Users with the root password can change the system.
Shocking!  No.  Not really.

The amount of misinformation in this thread causes me almost physical
pain.

Root can always change the date.  That isn't interesting at all.

The better attack against the clock is to attack the network side of
NTP.  If you can adjust the clock from the network (also not possible
in a default configuration) then you could get some grip on this.  But
by default you can't do that against NTP either.

DIMM sockets don't fail.  What fails is the power circuit supplying
voltage/current to the sockets.

Possibly.  If you look at the PCB below the caps you'll see a colored
residue there as well (gravity).  The caps get old, get hot, and the
aluminum casing separates.  When this happens the oil spills out and the
cap is done/dead.  This assumes a horizontal case.  If the case is
vertical then gravity will pull the oil along the bottom edge of the cap
cylinder wall and pool there before drying.  It may drip before drying
as well, so look at components nearby "underneath" the split caps.

Most mobo manufacturers switched about 5-6 years ago to using all solid
caps, no more oil/film parts.  These have a much longer lifespan.

Probably not coincidence.  But keep in mind other components may have
failed as well.  You could try recapping the board using your soldering
skills and one of these kits, or purchase individual caps for your
board:  http://www.badcaps.net/pages.php?vid=21

But given the cost of $25-30 and your time, the fact that recapping may
not be a complete fix, and the gear is 10 years old, you may be better
off buying new guts.  This seems to currently be the least expensive
Newegg AMD based combo:

Even with a single core at 2800 MHz clock the Sempron will run circles
around your twin MPs at 2x 2000 MHz clock, due to the 1 MB L2 cache (vs
256KB), the integrated memory controller, and dual channel DDR3-1333.
The Athlon MP 2400+ Socket A bus throughput is 2.1 GB/s or roughly 1.05
GB/s per CPU.  This Sempron combo?  21 GB/s, 10x faster.

Oh those photos were difficult!  :-)  But I think you definitely have
the bad capacitor problem.  Read about it here.

  http://en.wikipedia.org/wiki/Capacitor_plague

Compare the pictures for the bulging top of the capacitors in the
wikipedia article to the ones on your board.  But note that the
wikipedia picture is about the worst you will see which is why they
made a good text book photo.  Here is a photo from one of my LCD
monitors that had the bad cap problem.  As you can see they are not as
bad as what is on wikipedia.

  http://www.proulx.com/~bob/photo_album/2012-03-18-bob-samsung-fix/4.html

But those in my pictures are still bulging significantly.  I replaced
them.  This fixed the monitor.  I have actually repaired five LCD
monitors all with similar bad capacitor problems.  Now whenever anyone
has a bad LCD monitor that they think they should scrap out I pop it
apart and look to see if it is an easy repair or not.

You needed a tripod if anyone did!  :-)  Really hard to see but look
at the tops of the cans of the capacitors.  Are they puffed up even
just a little?  If so they they are bad and should be replaced.

> http://s8.postimg.org/i33u96j5h/DSCN1307_smaller.jpg

The reflection in the shiny part of the case actually looks more in
focus than the direct image!

If you don't feel comfortable replacing them yourself I am sure that
you could find an electrically inclined friend that would do it for
you if you bought the parts.  Hard to say but probably less than
$20USD in parts.  Caps that size are not cheap.  I am always shocked
by how much parts cost and you have many of them on your board.

Know any ham radio operators?  I am sure that among that group you
would find someone who would be able to help you with the soldering.
This is really the easiest of the repairs on circuit boards.

No, not that I could find anyway. However, it's still possible to get
to it from the web site. For the record:
Go to http://www.debian.org. Choose the CD ISO images link. Choose the
Download CD/DVD images using HTTP or FTP link. Choose the Official
CD/DVD images of the "stable" release link. Choose the link for your
architecture (only tried this for amd64 and i386). Then find the link
for the checksums you want md5, sha1, sha256 ETC. Should this be
easier to locate? Yes.

For the example you give.

The iso comes from:-
http://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-7.2.0-i386-netinst.iso

Looking at the parent page:-
http://cdimage.debian.org/debian-cd/current/i386/iso-cd/

The sums are listed on the same page. In this instance (SHA1) you'd want:-
http://cdimage.debian.org/debian-cd/current/i386/iso-cd/SHA1SUMS

The relevant entry for that particular iso is:-
c7050ae8ccda40456f6a1c4936ea8f170736b440  debian-7.2.0-i386-netinst.iso

So in this instance you *know* that the cd is intact.

Don't trust the sums? Why should you?
Those sums are signed by the developers:-
http://cdimage.debian.org/debian-cd/current/i386/iso-cd/SHA1SUMS.sign


$ gpg --output SHA1SUMS --verify SHA1SUMS.sign
gpg: Signature made Mon 14 Oct 2013 08:18:52 EST using RSA key ID 6294BE9B
gpg: Can't check signature: public key not found


I then download the key matching that ID from a keyserver (Debian CD
signing key (debian...@lists.debian.org) ID: 6294BE9B Fingerprint:
DF9B 9C49 EAA9 2984 3258 9D76 DA87 E80D 6294 BE9B.).
 and see it's signed by a bunch of people (17). By checking their keys
and the keys of some of the people who've signed their keys - I find I
"trust" the CD signing key "by 2 degrees". The world really isn't that
big after all! :)

NOTE: if you don't know someone who signed Steve McIntyre's key you
surely know someone who does know someone who did (or you've never left
the house you were born in, ever).

Mount the iso (# mount -o loop $someISO $somewhere) and you'll see the

Yes, there's /dists/wheezy/Release, but it doesn't include something
that is signed.

There is also /md5sum.txt, but it doesn't include something that is
signed.

I got it from here:

"Official netinst images for the stable release

Up to 280 MB in size, this image contains the installer and a small set
of packages which allows the installation of a (very) basic system." -
http://www.debian.org/CD/netinst/

This is the download:

That is what I want to do, not a self-test, but before I burn the iso, I

True.

But have you done a self-check. This a first step:
check SHAs.

OR self-check the digital signature of the Release.gpg file for your
release (eg Jessie).

See eg .../debian?/dists/jessie/Release.gpg

Your next step is to satisfy yourself that the signature/fingerprint
of the key you are using for self-checking of a CD for example, is
"safe".

So you need a sense of safety from the Debian Developers and their
network or not-network servers. This is a "take for granted" type
thing for me at the moment.

The next level of improvement in your sense of "safety" of the archive
signing key, is to check its fingerprint on eg, this site:

> http://www.debian.org/CD/verify.en.html
> http://www.debian.org/CD/verify.de.html

eg:
"
pub   4096R/64E6EA7D 2009-10-03
  Key fingerprint = 1046 0DAD 7616 5AD8 1FBC  0CE9 9880 21A9 64E6 EA7D
uid  Debian CD signing key 
"

For example, if you check the Debian signing key fingerprint from a
few random Debian mirrors, perhaps through a TOR proxy to some
overseas/ other country Debian mirror website, then you should be
_reasonably_ comfortable at that point, that the key fingerprint on
your machine or on your particular CD ISO, is in fact the "real
Debian" one.

The next level of improvement in your sense of safety regarding a
particular key (you are concerned that global internet monitoring and
NSA/KGB/etc bodies are all colluding to present to you a FAKE debian
archive signing key, from ALL the websites you have accessed, via
whichever network transport layers (direct through ISP, proxy through
TOR etc) you have checked through), is to physically build your GPG
"web of trust" or "chain of trust" - eg, host a keysigning party, and
invite a Debian Developer in your area.

At this point, your efforts would probably be best spent working to
become a debian developer, and to assist with development and auditing
of various "important" packages in the Debian archive.

You also might consider to rebuild various "important" packages and
libraries, eg GnuPG and those libs which do MD5 and SHAx hashing, and
verifying that you can create bit-identical versions, or at least
re-run your SHA and signature verification process using your custom
build libraries, and making sure you get the same verifications.

At that point, you might install some very old version of Debian (from
say 7 years ago), then build the libraries required to build the
"modern" libraries (or rather, library versions) for your SHA and GPG
sig key checking, and check your modern iso/archive veracity on that
old Debian installation.

At this point, you should have a pretty high level of certainty around
the veracity of the GPG keys and signatures and SHA signatures etc.

Good luck :)

Re: How to verify install iso?

2013-12-12 Thread Ralf Mardorf
You misunderstand me.

If I've got a checksum from the iso, e.g.

[rocketmouse@archlinux downloads]$ sha1sum
debian-7.2.0-i386-netinst.iso 
c7050ae8ccda40456f6a1c4936ea8f170736b440  debian-7.2.0-i386-netinst.iso

where can I find a file with checksums to check/compare?

I need a source and don't know where the source is.

If I download a key, I can decrypt a signed file including the checksum,
but where is that file?

I can not find such a file inside the iso, nor do I know a website to
download such a file.

Ralf

Huh?  You can download the key from the same location as you download
the iso. *Or* you can use the one on the iso:-
$ ls -x
autorun.inf   [BOOT]   css dists
  doc firmware   g2ldr

  *md5sum.txt*  pics   pool

There's no explanation where the checksum files can be found. The iso
does include a md5sum.txt and nothing else. There simply is no file for
comparison.

Keys for what? For a MD5SSUMS.sign file? The iso doesn't include such a

Aside from the methods exhaustively detailed in the links I've provided

e.g. with debian-7.2.0-i386-netinst.iso:-

Readers Digest version:-

Paragraph 1: Debian CDs are digitally signed so you can check for
corruptions and to prove they are baked by Debian.

Paragraph 2: To check the signature use an appropriate tool. "md5sum",
"sha1sums", or "sha512sums".[*1]

startx (with no per-user config) works, kdm has _issues_

2013-12-12 Thread Zenaan Harkness
So I have no per-user config, such as ~/.xinitrc , ~/.xsession and
~/.xsessionrc .

startx after linux console login works well.

When I login to Linux console, then run
sudo service kdm start, and then login from there to xfce,
my XFCE4 keyboard shortcuts don't work (Settings -> Keyboard ->
Application Shortcuts).

Any ideas why?

This is excellent advice.

Please Note: before these experiments, I simply had ~/.xinitrc, and
startx worked.

However, I was inspired by what is the new/current "debian way".

On a whim, I removed ~/.xinitrc and ~/.xsession and I have no ~/.xsessionrc .

So now things work as well as they did with ~/.xinitrc , but without
any ~/.x* files! This is good.

Clearly consolekit is started (logout, as well as reboot etc now
work), my keyboard shortcuts work etc.

This seems ideal - no per-user configuration, and it just works (TM)(C)(R).

Thanks

That brownish color you see is not flux. There would never be any flux 
on the top of the capacitors.
It's caused by the electrolyte leaking out. Probably a close inspection 
(after you have removed the part)
would show some fracture in the aluminum housing, or at least a hole. 
All the caps should show

just clean aluminum on top, like the other ones you see in the vicinity.

I would be tempted to replace these aluminum electrolytics with tantalum 
capacitors of the same or
slightly larger voltage and capacitance ratings. Under no circumstances 
use a lower voltage rating than what
you are replacing.  Much military hardware has been built with tantalum 
caps, but most consumer equipment

has not, because tantalums are quite a bit more expensive.

Whoever is going to do the actual work, remember that electrolytic 
capacitors--both aluminum and tantalum
--are *polarity sensitive*. they *must* be installed with the same 
polarity as those being replaced. The board
itself may be marked--I just looked at a Foxconn mobo, and it has a + 
sign next to each electrolytic cap. But
if not, before removing the caps, mark the board with a + sign where the 
positive end goes, or with a minus sign
where the negative side is. (Aluminum caps are usually marked with a 
white stripe at the negative polarity.
Tantalums, however, are usually marked with a + sign nearest the 
positive lead.)


Depending on the values you need, you might find them at Radio Shack. 
They don't have a large selection,
and their prices are about 5 times what the actual value is, but for 
three pieces, that's the simplest.

Otherwise, Digikey will definitely have what you need.

Changing Week start

2013-12-12 Thread Alois Mahdal
Hello,

regarding locales and my user account, I have kind of strange
taste, but I would like to know if it's possible to achieve
this (or at least indicate my preference to applications):

*   As a language of display (e.g. GUI messages), I want to use
English

*   As date format, I want to use Czech standard, e.g.

   "Út, 31.12.2013 13:45:31" for last day of this
   year, quarter to 2pm plus 31 seconds

*   When a week is displayed, I want to see Monday as the first
day


Of course I never had problem with the first one.

Time format can be specified using LC_TIME along with things
like paper format and monetary format, although most of the
time I just tweak it in the app (since it's usually only
xfce4-datetime-plugin where I really care).

However, I have yet to find a proper way how to define first
day of week.  Is this possible?   Or is there an ongoing
attempt to add this to standard LC_* arsenal as well?


Thanks,
aL.

PS: Although I said that my taste is strange, I suspect this
might be valid case for any English-speaking citizen living in
a non-English environment:  basically you want all in your
native language, except for things like dates, timetables and
prices, where you want to be consistent with what you see
everywhere around you.  (Disclaimer: I'm not that case, I'm
native Czech, I just prefer English for GUIs and WWW to avoid
distraction from incorrect/incomplete translations and to
learn English better.  And to explore new use cases ;))

Hi Kailash,

Yes, I do have to ask, so I know not to do.

Pics I can do. However, the angles a bit rough, me leaning on one leg, system

The exactly matching numbers is a coincidence, but overall it isn't.
Dying capacitors mean that the power rails they are attached to are no
longer nice and clean and smooth, but contain voltage spikes and
steps. When the voltage including these transients falls outside the
range in which RAM (or anything else) works, then it starts causing
errors. RAM draws quite a bit of current, and the higher the current,
the worse the spikes, so removing RAM may well take the voltage
back into the working range. The worse the capacitors get, the more
you need to reduce the current taken to get things working again.
Capacitors degrade prograssively rather than dying instantly, and you
can't see the loss of capacity, so the number that are visibly damaged
is a coincidence. They will all be on the way out.

So yes, replacing the capacitors is the only option. And as has been
said, it isn't a trivial job. It's easy in principle, but the board is
thick and the holes aren't that much larger than the wires, and the
wires are connected to large copper areas, so it's difficult to melt the
solder. Too small an iron simply won't do the job at all, you want at
least 50 Watts with a short bit or an equivalent hot-air rework tool.
Having removed the capacitor, it may be even more difficult to remove
the remaining solder from the holes, or at least enough to fit a new
component. If you succeed in removing the dodgy capacitors, look around
their positions to see if any electrolyte has leaked out, and if so,
clean it up. It's water-soluble and corrosive, and generally eats
copper and other materials, so don't leave it there, even if it looks
dry. It *will* eat the PCB tracks nearby.

Finally, these capacitors are chosen for very high ripple current
ratings at high frequencies, so any replacements need to be designed to
do this particular job. Obviously, use the same capacity and voltage
rating (not larger in capacity, as that may over-stress the switching
regulator which they work with, and not higher in voltage as it won't
do any harm but you'll be trading that for ripple current) and
preferably about the same physical size. The smaller the capacitor, the
lower its ripple current rating will be. The ripple rating won't be
marked on the capacitor, though you may be able to look up the model
number in a datasheet. Just get the highest ripple current you can find
for the voltage and capacitance and physical size, looking for figures
quoted at tens or hundreds of kilohertz rather than 50/60Hz values.
Capacitors designed for switching regulators won't usually have a 50Hz
value quoted anyway.

apt, aptitude and synaptic handle package install conflicts differently.

These tools do the same in trivial situations like installing or
removing package from the main archive.

But, put a number of packages with the same name and different versions
(add versioned dependencies to the picture) - and these 3 tools start
behaving differently. Add the fact that any package in backports
archive has special version that is _lower_ that any version in main
archive - and sometimes these tools may produce funny results.

Basically, apt provides you with the most dumb solution possible
(works most of the time) - install what you want, upgrade dependencies.

Aptitude gives you multiple ways of installing package (and one has to
choose carefully) - install what you want, upgrade/downgrade
dependencies (and may remove something just for fun :).

Synaptic assumes that you are not lazy, and will use Ctrl+E (IIRC, may
be wrong) to force particular versions for needed packages.

So, it's possible to use Synaptic for the task, it just will violate
the great IBM principle - 'People should think, machine should work'.

A agree regarding to the multi-layer, I only half agree regarding to
replacing the capacitors. Could you post a link to a photo? "rusty
looking" could be flux, it not implicitly has to be a broken capacitor.
We unlikely will be able to spot it by a photo, but you never know.

Correct, but I experienced that Debian's packages of memtest (e.g.old
stable) often didn't work correctly on my machine, when I used the same
version of memtest from a memtest iso, it did run without issues. The
same when I used memtest from Ubuntu. They seem to compile it different,
than it's compiled for the original memtest isos.

When I talk about memtest, I mean memtest 86+.

I would use it from here
http://www.memtest.org/#downiso

Debian anyway does provide version 4.20, while the iso comes with 5.01.

About a month ago, I found the box crashed again and beeping on reboot, so

tried them in that first slot and both worked. I tried adding some back and no

I think all the RAM is good, but the last three slots are bad (or maybe just 
the 2nd is bad, and then the 3rd and 4th can't work without the 2nd??).

Looking closer I see three capacitors on the board (nearer to the CPUS than the 
ram slots) have a rusty looking coating on the top. One is worse looking than 
the other two (eh?), the two have some part of their tops that still look shiny 
silver. I've heard of capacitors going bad on motherboards, but never saw any. 
Is this rust a sign of failure and could their failure be the cause of the RAM 
slot problems?

Other than the lockups/memory beeping I've never really seen any issues with 
this system (did replace bad drive once or twice). It has boinc/seti/asteroids, 
webserver(s) and other stuff running (except when running BOINC its not heavily

Are three rusty capacitors and 3 bad slots just a coincidence? Thanks.

As far as I know, memtest will just run until you stop it. If you
have it running for say 10-12 hours, and it just prints successive
tests that it's doing, then your ram is probably fine. I would
personally move on to checking the rest of the hardware at this point.

You won't get any error messages. The system will execute valid commands

if it was bad, and on the first one, the one in slot 4, after taking it out, it 
rebooted and worked fine. So I figured that stick was just bad and left it at 
that. I didn't have any other sticks of the right DDR type and I didn't bother 
to replace it.

About a month ago, I found the box crashed again and beeping on reboot, so 
going through the same elimination process found only the stick in the first 
slot would work. It seemed odd two sticks could go bad at the same time, so I 
tried them in that first slot and both worked. I tried adding some back and no 
matter the combination except for one single stick, always got a beep-fest. So 
I think all the RAM is good, but the last three slots are bad (or maybe just 
the 2nd is bad, and then the 3rd and 4th can't work without the 2nd??).

Looking closer I see three capacitors on the board (nearer to the CPUS than the 
ram slots) have a rusty looking coating on the top. One is worse looking than 
the other two (eh?), the two have some part of their tops that still look shiny 
silver. I've heard of capacitors going bad on motherboards, but never saw any. 
Is this rust a sign of failure and could their failure be the cause of the RAM 
slot problems?

Other than the lockups/memory beeping I've never really seen any issues with 
this system (did replace bad drive once or twice). It has boinc/seti/asteroids, 
webserver(s) and other stuff running (except when running BOINC its not heavily 
stressed but generally is doing _some_ work pretty much all the time).

Are three rusty capacitors and 3 bad slots just a coincidence? Thanks.

Keep .xsession as a contant. You know it makes sense.

I have let it run over night, it is still going, but no errors so far. Would

1. Running startx basically runs xinit.

3. startx now searches for the system xinitrc in /etc/X11/xinit/. This
   contains the line

  . /etc/X11/Xsession

   and Xsession will use ~/.xsession if it exists.

So startx on Debian uses .xsession :). However, it does not consult it

Indeed it does. It goes on to use /etc/X11/Xsession. :)

Should some of the xs have a '.' in front of them? startx and .xsession
should (except in exceptional circunstances) be found together. A good
way to foul a system up is to use .xinitrc or .xsessionrc by itself with
startx because the files in /etc/X11/Xsession.d then do not get used.

It accepts 'SYSFS' or 'ATTR', no difference, and accepts *either* rule.
But still does not run the script. 

This is on a up-to-date 'jessie' system, with a basic Kindle (costing
£69 from Amazon, the basic model). Just so that we can perhaps see the

I attach a screenshot showing the kindle open in thunar. You'll see I

be mounted by hand, so the problem is not just with the kindle, its
system-wide. 'thunar-volman' is loaded, but I still have to mount by
hand, whichever file manager I use.

Gotcha. :-)

Ah, ok.  While, yes, MS decidedly doesn't support it, I was actually
thinking in terms of 32-bit addressing - which *would* only support up
to 4GB.  Thanks for the mention of PAE; I did a quick search on it and
found the following at Wikipedia:

"In computing, Physical Address Extension (PAE) is a feature to allow
32-bit x86 central processing units (CPUs) to access a physical address
space (including random access memory and memory mapped devices) larger
than 4 gigabytes.

"First implemented in the Intel Pentium Pro in 1995, it was extended by
AMD to add a level to the page table hierarchy, to allow it to handle up
to 52-bit physical addresses, add NX bit functionality, and make it the
mandatory memory paging model in long mode.[1] PAE is supported by Intel
Pentium Pro and later Pentium-series processors except most 400 MHz-bus
versions of the Pentium M.[citation needed] It is also available on AMD
processors including the AMD Athlon and later AMD processor models."

And it went on in all kinds of details from there.

So there are some nifty hardware tricks that let you get around the
limitation.  Good stuff! :-)  Thanks for the info.

You could try following the advice given in

   /usr/share/doc/xfce4-session/README.Debian

Selectively quoting we have

   * only use startx, without any argument
   * don't use a .xinitrc, use .xsession

and later

   Then you need to fine-tune your pam installation so ConsoleKit
   can be sure that your user is correctly authenticated. For that,
   you need to:

   * install libpam-ck-connector
   * put:

   
   session   optional  pam_loginuid.so
   

   *before* pam_ck_connector.so in /etc/pam.d/common-session.

This works for me.

> In the meantime, it looks like I'll have to go back to using .xinitrc

Then your X session is probably not set up correctly so you will have to
deal with that in the .xinitrc.

Huh?  :/


Which distro ships a pae kernel with highmem64G *disabled* in the

I don't know?

He was asking for CLI statements and those above are the statements, if
you download the vanilla kernel source from kernel.org and build a
32-bit kernel, for e.g. Debian. Yes, there are other CLI statements too.

Why do so many people, with 64-bit architecture prefer 32-bit operating
systems?



Maybe it's because some software is not available for 64-bit systems,
and the devs won't provide what I think is called multi-arch so that
32-bit programs run on the 64-bit system. It's a trade-off--you can have
a distro that supports 32-bit apps on a 64-bit system, but then you have
to put up with all the BS that that distro imposes on you.

Yes, in any situation except playing certain 3D games.

I use an i3-3225 to drive 1920x1080; it does very well at video
playback and random desktop use.

Note that ~/fonts would be sufficient here.
For your own convenience you can put your fonts in any sub- or
sub-sub-directory and they will still be seen.

Under these, too, you can create any directory structure you like,
without having to specify it in ~/.fonts.conf.
Not sure why you prefer ~/fonts over one of these, but never mind,
it's not that important.

sound problems after upgrade

2013-12-12 Thread Christopher Judd
Hi,

I have a testing box, kernel 3.2.0-3-amd64, using KDE.  After an 
upgrade earlier this week, I am having problems with sound.  The system is an 
MSI 760GM-P23 motherboard with onboard RealTek ALC887, and sound has always 
worked fine previously.

The problem is that there is no sound output from Amarok, or when 
I try to test the various sound devices from the KDE system config window.  
Sound works fine in VLC, however.

I have phonon configured to use the VLC-phonon backend; 
pulseaudio is not installed.  

How can I determine where the problem is, or which package is 
broken?  Thanks.

-Chris

And I'd don't. 'dist-upgrade' can install new packages (and _usually_
nothing breaks from installing new packages), but more important - it
can _remove_ existing ones (and that _surely_ can break things).

'apt-get upgrade' on the other hand is usually considered safe enough.

I just added the Orage Clock Applet to my panel and can select the
timezone and configure it to display the time zone of choice, in this
case UTC.  It looks like every time zone known to the system is
available.

Neither version "displays" the Kindle on my systems. udisks does. Your

That's intentional. Failed upgrade needs human intervention, and that
trick is hard to accomplish if the box goes down.

Still, if one has desire to blow legs off:

sudo sh -c "apt-get update && apt-get upgrade -y ; poweroff"

Sure, if you don't mind using dash instead of bash, 'sudo sh' and 'sudo
su' are the same. 

Also, 'sudo su -' and 'sudo -i' set up all root environment variables
(specifically, $HOME). 'sudo sh' keeps $HOME, which can lead to
not-so-funny things.

Thank you for sending me back to the man page to check the real
meaning of dist-upgrade! I thought it was for hot distribution level
upgrade but it has also an use for normal software packet updating.

I thik I will stick to upgrade and accept to have some packet held
back. My work was not hindered by that, at least until now...

Good point, I don't use apt that often, because my "main" distro isn't
Debian. I guess there's an option to always confirm. Btw. dist-upgrade
anyway might be better than upgrade.

For newbies it's hard to search for information about Linux, because
they don't know the terms, as long as they don't know the structure of
Linux and in addition it's hard to distinguish the good, the bad and the
ugly websites.

Sorry, it may ask if it has to preserve or not a configuration file

You don't say what parts of Wheezy (2+ packages) you've installed,
I'm presuming GNOME. Someone here can advice you on how to use the GUI
package manager for GNOME (I 'think' it's Synaptic).
http://debian-handbook.info/browse/wheezy/sect.apt-frontends.html#idm140081895704256

Not difficult to install. If you know what a console is and how to
become root it's just a matter of, as root, typing:-
apt-get install -y openoffice.org

When you're more comfortable installing software in Debian you may wish
to run the latest Apache OpenOffice.org. See:-

Already installed on your machine will (should) be this FAQ:

file:///usr/share/doc/debian/FAQ/index.en.html

Browse to it with your web browser.  From this contents list, section 
8 provides a fair bit of information.  Appreciate you are looking for 
simple descriptions, so you may want to skim some of this.


Once you begin to feel your way around, you want to 'search' for Open 
Office.  Software for installing is held in 'repositories', so you 
will need to search them for open office.  I use a GUI for that, 
Synaptic, but if you are using terminal, the Aptitude program may help 
you.


I was a bit confused at first, too.  Don't do what I did, which was to 
install packages (*.deb) direct from source sites - the Debian 
installation ends up getting a bit cluttered with co-existing older 
and newer versions of things.  I recommend sticking with Debian 
releases of programs, if at all possible.


regards, Ron

apt-get upgrade will ask the user to upgrade or not and that is wanted,
assumed the update was successful. This line is ok, I just have doubts
if there is anything less good with using sudo sh, I will ask detailed
about it in some minutes, since I have to reboot first.

Let's attempt to get a colour transformation to black and white. :)

Firstly: .xsessionrc is for holding ***global environment*** variables.
The emphasis is mine.

Secondly: 40x11-common_xsessionrc in /etc/X11/Xsession.d is sourced
before 50x11-common_determine-startup. So .xsessionrc is read before
.xsession and any environment variables set will become available to
applications run by the commands in .xsession.

Thirdly: Everyone likes a test to do. :) Create .xsessionrc with
contents similar to these:

   xterm &
   TZ='GST-10' ; export TZ
   exec 

Now execute 'startx'. You have a functioning system? Execute 'date'.

Putting commands in .xsessionrc is very naughty. Are you still there,
Charlie? For your own good, please stop doing it.

How to install Packages on Debian-Wheezy

2013-12-12 Thread Wally Lepore
Hi Folks,

Recently completed a successful install of Wheezy in Virtual Box. Runs
great but slow (for obvious reasons). I'm not looking for
speed/performance at this point but just looking to learn the
interface, access and perform functions in terminal (as well as root
terminal) and run basic programs.

I would like to locate a link that explains in simple terms (if that's
possible), "How to Install Packages". I've been hours reading about
this topic via many links but find them helpful to some extent but too
advanced.

The link below was helpful but then it became difficult to understand.
I prefer not to start executing commands in root terminal if the
instructions are a bit overwhelming (at my current level of
understanding).

http://www.aboutdebian.com/packages.htm

I'm searching for a complete beginners guide that details "simple to
understand instructions" on "How to install packages" as well as other
general "how-to's" in Wheezy (current stable). I would much appreciate
any links and/or suggestions.

My initial interest is to install "OpenOffice". I understand wheezy
has LibreOffice aready installed but I need OpenOffice as well for a
project I'm currently working on.

Thank you kindly for your patience and help.

Exactly! Kinda like house fire insurance (or any kind of insurance for

A good passphrase for the encription will slow down (even halt if you
are lucky) an attacker that has complete control of your machine,
while no password will protect a computer that is physically in the
hands of the enemy.

Is that a statement we can agree ? BTW, it's my point of view.

Yes - especially if you say no password will completely protect a computer.

No, having one user with ALL=(ALL) ALL by default AND having

credential caching.

The problem is not strictly technical. There is no technical difference in
guarding an account with id 0:0 that you can access by direct logon or
having root unreachable by logon and one user that can become root via
su or sudo.

The problem is in the usage of the account, it's a psychological one:
your everyday account is your everyday account, and using it with
strict security - as appropriate for an administrative account - could
be what someone labels "a PITA". And this relaxed behaviour may lead
to security breaches.

Credential cache hijacking in sudo is one of the paths an attacker may
use: the change of the timestamp was a trivial one to find and has
been fixed; I fear that subtler attacks may be possible.

And in these case is not that sudo is misbehaving. My opinion is that
the poor program as been abused.


Yup - i agree with all of this.

Cheers

Iain

There are old 32 bit PAE only machines around with plenty of capability
today, albeit with a lot more space and power consumption for the
performance.  Take the Unisys ES7000 Orion 230 for example.  It's a 32
processor Foster Xeon 72" mainframe, 32 bit PAE only CPUs.  Original
price when new in 2001 was ~$300,000 USD.  Today?  A few thousand, if
you could find a complete working unit at a surplus equipment dealer or
on Ebay.

CPU count:  32
CPU type:   Intel Xeon MP Foster, first gen NetBurst
Specs:  1.4-1.6 GHz, 256KB L2, 1MB L3
System cache:   256MB static RAM, 32MB per 4 CPU module, 8 modules
System RAM: 64GB ECC SDRAM, 128x 512 MB DIMMs, 32-way interleaved
RAM bandwidth:  20 GB/s sustained, 25.6 GB/s peak
IO Slots:   64 PCI 2.1 66 MHz
32 PCI 2.1 33 MHz
IO Bandwidth:   5 GB/s sustained

There are a number of workloads at which this 13 year old PAE only
system would offer excellent performance today.  It would make one
heckuva server for web, mail, database, etc.  It would have decent SETI
or Folding throughput though individual work unit processing would be
pretty slow compared to today's CPUs.  You'd be hard pressed to find a
32 bit PCI FC400/800 or SAS controller, but Intel still sells a PCI GbE
card.  This allows for MPIO iSCSI over multiple HBAs and GbE links to
modern iSCSI SAN RAID arrays.  Say 16 HBAs, 4 links to each of 4 arrays
with 24x 2.5" SAS drives, 96 drives total, 3.2 GB/s throughput.

This is obviously an obscure and unlikely scenario, but it is a good
example of why one would choose to run a PAE kernel.

use: the change of the timestamp was a trivial one to find and has
been fixed; I fear that subtler attacks may be possible. 

And in these case is not that sudo is misbehaving. My opinion is that
the poor program as been abused.

Maybe that's what I read? Anyway, I renamed the file ~/.xsession and
the system booted without problems. I thought it took a little longer
but that was probably my imagination as I expected it to fail.

Thanks for the good information.
