LVM problem

2010-04-15 Thread Luc MAIGNAN
Hi,

I want to add a new disk (/dev/sdb1) to an existing VG.

Here what I've done :

* pvcreate /dev/sdb1
* vgextend VolGroup00 /dev/sdb1
* lvresize -l +20901 /dev/VolGroup00/LogVol00

(LogVol00 is mounted on /)

Then, when I make a 'lvdisplay' I saw the correct size of the volume 
(sum of the old size plus the size of the new disk)

But a 'df -kh' always gives me the old size...

What's wrong ???

Thanks for any help

Regards

 Dear all,
 
 I'm using FC8 and I download the kernel source 2.6.33.2 from
 kernel.org and build it by myself but,  everytime I try to boot from
 the new kernel I met the error No Volume Groups Found.
 I tried everything I could but failed still.
 Would you please give me any idea?
 Thanks in advance.

Are you sure you have compiled all the needed
pieces (such as modules)?

You should compare the kernel messages in the working and
not-working case.

Running a root GUI login is very much frowned upon. What exactly are
you trying to accomplish? The system-config* tools will prompt for
root authentication if necessary or you can su (or sudo) to root in a
terminal session or login as root in a virtual terminal.

documenting the actual case histories of horrible

You mean the cases where everything works correctly? If everything
worked correctly and there were no bugs, and our systems weren't
Internet-connected, and we understood the implications of everything we
did, and we never typed or clicked on anything we didn't mean to, why
would we need the concept of root?

I suspect that he wants to execute a privileged operation from the GUI,
not that he wants to run the GUI from root, though the question is

One scenario is when the normal users are all defined over nis/nfs, and

To fix things in a scenario like that, I boot into runlevel 3 (by 
temporarily appending 3 to the end of the kernel line in grub), login

 Hi Folks,

 I admit to being new to mobile computers, laptops, netbooks, etc.

 there are more states on these systems that a desktop usually uses,
 including sleep and hibernate.

 is there an URL somewhere that will tell me how to recognize these
 different states and
 return my netbook to normal operating mode once the state of drowsiness
 is established?

 i fire up my asus netbook in the am and when i don't use it for an hr or
 so, it goes
 to sleep (or maybe hibernate) mode. the power button light is still on.

 but the only control i get is pressing and holding the power button
 until i get a shutdown.

 would some kind soul point me to a state managment URL?

This page describes the acpi power states:

http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface#Power_States

On my hp laptop, pressing the power button once will cause it to wake
up again. On my old asus laptop (running f11 i think) this didn't work
properly, though it would try to resume. If you don't want it to
hibernate at all, you need to change the power profile. For kde this
under the advancded tab of the system settings.

HTH,

Not here.  Once you've authenticated, that info is cached for a few
minutes, and automatically renewed as you keep on doing things as root.
And, if you are going to be idle for a while, you can manually extend
the period without having to type in the password again (there's an icon

Yeah, well, the *usual* thing that cause problems is - the user stays
logged in as root, does all their work as root, all *their* files are
owned by root, so they have to keep on logging in as root to use their
files.  They paint themselves into a corner, then use that to justify
why they need to be root.

If you want further ideas about what goes wrong, go back through the
list and look at some of Gene's posts.  He runs as root, and comes a

Traditionally IRC (as root) users have their problems, it's just making
it easy for them to become a zombie.

SSH tunnel for ssh traffic

2010-04-15 Thread Christoph Höger
Hi,

I need to ssh to some remote VM that sit in a private LAN. For any other
service (e.g. RDP) I'd use ssh tunneling just normal.
But what do I do for ssh traffic? Since ssh is not host agnostic, it
will always complain about localhost having a different RSA key.
I just do not want to edit the known_hosts every time I need to connecto
to a new machine!

Is there some way to tell ssh to use a tunnel directly for a connection?

  I just run the required GUI application as a root user. It's a trivial
matter to create a desktop short cut that will run as a root user. IMHO
this is a better option, as it is inherently more secure. But then I
prefer to restrict root user access to only those applications that need
it. So I think the Fedora team are right to not have a GUI root login.
  This is my preference and in no way is it a criticism of any choice of
solution others may decide to adopt.

You could use a nonstandard port for the connection. known_hosts
includes the port information when the port is not 22 - it looks

Yea, some sort of pam change seems familiar. I haven't paid
much attention since I switched to KDM (for plenty of other
reasons besides the occasional root login - things like the
ability to modify the X server args to remove the -nolisten tcp).

Really? When did that start happening? It always honks about
localhost changing when I do it. My general solution is to
add the CheckHostIP no option to ~/.ssh/config and then
define different aliases for localhost and use different
ones for different forwarded connections.

I have a machine which changes RSA key every boot (boot from read only USB key).
The messages you are trying to avoid go away withi this in ssh_config:

  Host myhostname
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null

you should have localhost instead of myhostname.

(are you really worried about someone hijacking localhost?) :-)

On my Asus laptop, pressing any key would wake up from a suspend to RAM,
as the computer isn't completely shut down in that mode.  If you had to
press the power button, then there's some problem with hibernating on
that computer.  Suspend to disc would require pressing the power button
to resume, as the computer is actually turned off in that suspension

I needed the closed-source RPM Fusion packaged NVidia drivers for

or for suspend to disc, as well.  I don't want to remove it just to

 Right. You can type things you don't mean to as easily as click
 things you don't mean to. I'm just looking for the actual evidence
 that GUIs are fundamentally evil when running as root, not all
 this vague handwaving Oh, it must be horrible! stuff that seems
 to be entirely anecdotal or possibly completely imaginary.
   
While not a disaster of epic proportions, I've seen non-techies login
as root for a GUI session to do some minor admin work.  Then they decide
to do a few other things, forgetting or not knowing their actions
under root would have consequences.  Their actions would create files
and or directories in user's areas (most time their own).  They would
then stay logged in as root for an extended time since they were happy
to continue working.  At some point, they'd logout and later, next
day...after lunch, login as themselves and now have all sorts of
troubles they didn't have before.

Since they were non-techies they didn't know the concept of
file/directory ownership so permission denied was a real shocker.  So,
they'd log back in a root and try to fix things only to make them
worse...or make things insecure.  Directories which were previously 755
became 777.

Most of these folks had no concept of command line utils and did all
their administration after clicking on a icon.  Had they stuck to that
as a regular user and simply typed in the root password they most likely
would have done less damage to their system.

I see it as bad practice to login as root for a GUI session.  I'm
experienced and I've not logged in a root for GUI session in years.  I
do, however, have sudo configured to not ask for a password.  Some would
consider that unsafe.


 P.S. The simplest way to login to the gui as root is to switch
 to KDM instead of GDM as your login manager. KDM has not yet
 been taken over by the paranoid thought police :-).

 Hi, Kevin.
 
   The source of my nagios-plugins package is the EPEL repository from

You probibly want the 'epel-devel' list then. 

EPEL is in general much more conservative than Fedora when it comes to
changes. nagios in EPEL has been packaged the same way for many years. 

I suspect you had a version from another repository (dag? atrpms?
rpmforge?) installed that used a different setup, and only recently the
epel version passed that version so it updated.

If you want to log in as root, you will have to start by logging in as a

Run 'grep -H -n != *'
You should see something like:

[r...@tor1 pam.d]# grep -H -n != *
gdm:3:#auth  requiredpam_succeed_if.so user != root quiet
gdm-password:3:#auth required pam_succeed_if.so user != root quiet

gdm.rpmsave:3:#auth required pam_succeed_if.so user != root quiet
racoon:3:#auth required pam_succeed_if.so user != root
xdm:3:#auth required pam_succeed_if.so user != root quiet

except in your case, there will be no '#' preceding the 'auth' in those 
files. Edit to add the '# in all of the files your system lists, thus 
commenting out the line. Those lines make the authentication process 
quietly fail, if you are root.
Stupid idiotic nanny-statism circumvented.

There will be a test however, to see if this works and that you are 
awake. This test should have been done 15 days ago. Do 'su -', 'cd /' 
and then 'rm -rf *'. If you cannot log in after first considering 
whether you should follow these instructions, and you in fact followed 
them, then you have failed.

I'm afraid I do not understand what you are asking.

Let me try to answer what I think you are asking.
I apologize if I'm wrong.

Let us say I want to ssh tunnel to a remote machine on a remote lan.
Let us say I want to tunnel ssh traffic through this ssh tunnel to
still a third machine on that remote lan.

Could I do something like the following in my ~/.ssh/config file:

Host remote
 HostKeyAlias myAliasForRemote
 HostName remote.com
 LocalForward  veryremotehost:22

Host veryremote
 HostKeyAlias myAliasForVeryRemote
 HostName localhost
 port 

Now, could I do
ssh remote
and myAliasForRemote is what is associated with the host in my
~/.ssh/known_hosts file.
and as long as this connection is open, could I do
ssh veryremote
and myAliasForVeryRemote is what is associated with the host,
veryremotehost, in my ~/.ssh/known_hosts file.

I am not sure if the DNS name, veryremotehost needs to be resolved
locally or remotely.  I think it is remotely, but you would need to
check.  Normally, I would have used IP addresses because the hosts on
the company's internal lan did not have DNS entries.

The HostKeyAlias controls the name used for the host that is stored in
the ~/.ssh/known_hosts file.

Is this what you are asking?

Being immature, opinionated, or even certifiably insane doesn't make him

Root access by incompetents is a bad thing, the interface is moot. But 
at any level of competence forcing people to do things in a complex and 
unfamiliar way make errors more likely. I have scripts to do things I 
only do a few times a year, as well as set of notes that would have been 
a wiki had there been such a thing when I started. Bozo should not have 
root, anyone so trusted should be allowed to use the best tools available.

Your whole argument only makes sense if you accept the first sentence as 
true. And frankly I don't, at least using standard Fedora menus.

What tools do you install that would wreak such havoc? I'm looking at 
the menus (FC13 at the moment) and I find the set of things needing root 
and the set of things a user trusted with root would want to do have 
little overlap and minimum danger. Unless you trust root to people who 
are clearly incompetent, what would they do from GUI that they could 
screw up worse trying to do it from CLI? Some users have never *seen* a 
CLI, and find it a neat new feature. I didn't make that quote up. ;-)

 All that being said, if one is a godlike user and/or is willing to
 deal with the carnage that can (note I said _can_) ensue with root-
 based GUIs, then by all means edit the pam files and have at it.  No
 one is stopping you.

Good. Because if you have root password then all you have accomplished 
with nanny login is to force the user to type the root password for 
every GUI, or force the user to try to use su and a possibly unfamiliar 
CLI to do things.

I have a high resistance to giving just users root in any way, much 
less blocking access to tools which might do the wrong thing but would 
at least do it correctly. I have pissed off several managers by 
requesting a signed authorization to give root to people who are not 
administrators. And covered my ass once with just such a paper, I am not 
a trusting person.

I wouldn't worry about GSS failure.  You haven't set it up.
- From URL:

it explains the idea behind GSS.  I tend to think of GSS as Kerberos.

 where do i find the minor code its referring to?
 
 any ssh guru's out there to provide  a clue?
 

Not sure.

When it says, Agent admitted failure to sign using the key.,
is it referring to ssh-agent?

There is a program, ssh-add, which talks to ssh-agent.
I haven't used ssh-add or ssh-agent in a long time.

Before I take us down this path which might be a wild good chase,
I better ask are you using these?

Whenever I have publickey authentication problems,
it usually is file and directory permissions.
You indicated you checked ~/.ssh and ~/.ssh/authorized_keys

As a test, could you make certain your $HOME directories,
on both the local and remote machine, are not writable by anyone,
but owner?

Could you make sure ~/.ssh on both machines is only read/write
by owner?

Could you make sure the files in ~/.ssh, such as authorized_keys,
config, id_rsa, known_hosts, are only read/write by owner?

For me, anything in ~/.ssh should only be read/write by owner.
Call me paranoid but only owner should have access to these files.

The one kicker, I'm asking you to do, is make sure both
$HOME directories are, at most, readable, by others, and not writable.

If you want someone to put files in your $HOME directory area,
can you set up $HOME/droparea and give them read/write access
to $HOME/droparea?

Given that you say so yourself, the logical question is why do you need
Clamav? Clamav is usually installed by people running mail servers for
users who access them from Windows. If all you're doing is reading mail
in Linux, it's extremely unlikely that you even need it. In 35 years of

 Given that you say so yourself, the logical question is why do you need
 Clamav? Clamav is usually installed by people running mail servers for
 users who access them from Windows. If all you're doing is reading mail
 in Linux, it's extremely unlikely that you even need it. In 35 years of
 using first Unix and then Linux, I have yet to see a single virus that
 wasn't a proof-of-concept demo.

This is really what I have been wrestling with myselfwhy do I really 
need it

Is Fedora really that secure?

I come from windows and I am amazed at how not secure windows is.

So thank you as I don't really need it.

The only time I get a reaction from Virus software with linux is when I 
put in a windows 7 backup dvd

Even if we limit the discussion to email viruses, that's a very complex
and difficult question (to which the answer is yes :-). It's not an
attribute exclusive to Fedora as such, but to all Unix-based systems,
mainly for three reasons:

1) The mail client isn't running as root.
2) Even when running as root, Linux mail clients won't blindly execute
attachments.
3) Even for executable attachments, the virus is written for Windows and
won't run on Linux.

Of course it's in principle possible to get past all the above barriers,
so *in theory* you can have a Linux virus, assuming the user is stupid
enough to run an unknown executable. As I say, I've never seen one in
the wild.

 I come from windows and I am amazed at how not secure windows is.

See (3) above. Most viruses are written for Windows as it's the most
popular platform. MS likes to pretend that's the only reason it gets all
the grief, but there are other factors.

 You could use a nonstandard port for the connection. known_hosts

Well, the point being that in this case some directories were set to

gain access to other people's personal files, photos, etc.  Yes, it is a
local exploit.  But, if some guy had emails about his colleagues he
didn't want to get out...or his cache file was filled with trails of
visiting porn sites...or...

I suppose you'd find that OK...and just chalk it up to idiots.  But
that is one of the reasons for making it hard for folks to login as root
from the GUI.  To protect them from themselves. 

Yes, some people's view is that everyone should have the choice to shoot
themselves in the foot.  Some people think their children are very
intelligent, and well taught so there is no need in the world for child
guard caps on medicines and other bottles.   Sure, it a pain for older
folks with no children in their household...but I think they can request
non-guarded bottles at the pharmacy.   So, the choice is there to opt
out.  And the choice to opt out with regards to the root login exists. 
But, it isn't easy to do it for the simple reason that if it is easy to
do...the idiots would be the first ones to do it.

My reasons for not allowing root access for GUI logins is different than
what others have and for what you're looking for proof of.  IMHO, my
reasons are more fundamental and more likely to have real world impact.

 This comes very close to my needs. Only one thing left: Is there any way
 to trigger ssh remote just by running ssh veryremote?
 

I always started ssh remote manually.

Could you create a bash shell script that starts ssh remote in the
background, and then starts ssh veryremote?

- From the man ssh page, there is a suggestion about using
  The following example tunnels an IRC session from client machine
  “127.0.0.1” (localhost) to remote server “server.example.com”:

  $ ssh -f -L 1234:localhost:6667 server.example.com sleep 10
  $ irc -c ’#users’ -p 1234 pinky 127.0.0.1


Perhaps you could do something like:
# Please note...I have not tested this.
#!/bin/bash
# establish the initial ssh tunnel putting it in the background
ssh -f remote sleep 10 
# wait 2 seconds for ssh to set up the tunnel, hopefully long enough
sleep 2
# establish the ssh tunnel to the very remote machine.
ssh veryremote

I prefer starting ssh -f remote sleep 10  manually to know the ssh
tunnel is actually started before I start using it to forward traffic.

Other than using a bash script, I can't think of a way to trigger
the starting of ssh remote.

On another note, they added a ~/.ssh/config option that is new to me.
For those having problems with a home directory shared across multiple
machines, from man ssh_config,
they added NoHostAuthenticationForLocalhost

NoHostAuthenticationForLocalhost
   This option can be used if the home directory is shared across
   machines.  In this case localhost will refer to a different
   machine on each of the machines and the user will get many warn-
   ings about changed host keys.  However, this option disables host
   authentication for localhost.  The argument to this keyword must
   be “yes” or “no”.  The default is to check the host key for
   localhost.

Wifi link iwl3945

2010-04-15 Thread Kurian Thayil
Hi All,

Since the installation of F12 in my Acer Aspire 580 series laptop with
Intel 3945ABG wireless module, I am having the issue where my Wifi link
gets deactivated and activated (disconnects  connects) frequently. AP
is a Netgear WGR router with WEP enabled. Was using Debian GNU/Linux
(Etch  Lenny) and I was able to work without any issues. The following
is the /var/log/messages when a typical wifi session is disabled and
enabled. This issue was severe when there was no security enabled in the
router (I gave only MAC address level security). When I included WEP, it
became better. Module iwl3945 is loaded in the kernel along with
iwlcore, mac80211. Any idea on how to avoid this completely?

Some question in include\linux\I2c.h

2010-04-15 Thread mojian4linux
Hi all.
 when i read the include\linux\I2c.h,  i have a question   between 
--
/* include\linux\I2c.h */
  ...
/* Standard driver model interfaces */
int (*probe)(struct i2c_client *, const struct i2c_device_id *);
int (*remove)(struct i2c_client *);

/* driver model interfaces that don't relate to enumeration  */
void (*shutdown)(struct i2c_client *);
int (*suspend)(struct i2c_client *, pm_message_t mesg);
int (*resume)(struct i2c_client *);
...
--
Q:
1. /* driver model interfaces that don't relate to enumeration  */--what 
does this sentence mean?
2. what  the different between 
int (*resume)(struct i2c_client *) 
and 
int (*remove)(struct i2c_client *)
?

Re: Wifi link iwl3945

Hi All,

Since the installation of F12 in my Acer Aspire 580 series laptop with 
Intel 3945ABG wireless module, I am having the issue where my Wifi 
link gets deactivated and activated (disconnects  connects) 
frequently. AP is a Netgear WGR router with WEP enabled. Was using 
Debian GNU/Linux (Etch  Lenny) and I was able to work without any 
issues. The following is the /var/log/messages when a typical wifi 
session is disabled and enabled. This issue was severe when there was 
no security enabled in the router (I gave only MAC address level 
security). When I included WEP, it became better. Module iwl3945 is 
loaded in the kernel along with iwlcore, mac80211. Any idea on how to 
avoid this completely?
