[CentOS-es] Clonacion de disco

2008-10-29 Thread [EMAIL PROTECTED]
Hola a todos,

Tengo un servidor CentOS 5.2 con un disco de 40 GB y lo he clonado con el 
programa G4L a uno de 250GB, todo va bien, excepto que me marca que el disco de 
250GB es de 40GB y si voy a administracion de volumenes logicos me sale el 
resto del espacio de disco pero como uncategorized y me pone particinonar 
manualmente.

Mi pregunta es ¿como particiono lo que me falta de disco?

Gracias.

Re: [CentOS-es] dhcp y control en proxy

2008-10-29 Thread Wilder Deza
mmm. pues tendrias que poner una lista en /etc/squid/red_wireless, donde 
el rango de ips para esa red wireless, luego de eso


luego crear una acl con horario de uso, paginas permitidas, etc.

ejemplo
#defines el rango de ips de la red inalambrica
acl range_wireless src /etc/squid/range_wireless

#definimos la hora de disponibilidad
acl time y algo más q no recuerdo la sentencia..
#contenido del archivo range_wireless
192.168.1.10
192.168.1.x
192.168.1.x
192.168.1.20

#establecemos la regla de control
http_access deny range_wireless !tiempo

con esto le estas diciendo que para la red inalambrica le estas 
denegando el acceso pero más no en el lapso de tiempo pongamos 8:00am-7:00pm

[CentOS] cmirror - CentOS

2008-10-29 Thread Rajagopal Swaminathan
Greetings,

I might have missed something in the list here.. But could someone point out
some introductory material / docs regarding cmirror?

Is there something (even beta would do) in CentOS to read and understand
about this?

OT- On Fossils:
While I cannot claim Fossil state anywhere near some of the people who
were doing cards -- I knew about them though -- when I was born, I have had
my spell flicking switches to select boot device on a Texas Instrument DS
990 switching between the Washing machine disk and the 9 tape drive. (Now
this is in India when a lot of restrictions -- both by Indian and other
governments -- were there in Technology imports) The interesting part of it
was the entirely memory mapped design and barely a few registers...
and then in Prime 750 which had 5 huge boards which constituted a CPU. and a
hefty amount of RAM -- 8MB. The thigs is they worked 24x7 and we were
required to give a month's notice before shutting them down / rebooting
unless there was a breakdown which was very rare. Just like Linux
^H^H^H^H^H^H Centos Servers

IMO, all acronyms are obscure. That is their primary purpose -
obscurity. This enhances the exclusivity of those in the Profession
and slows the entry of new blood, thereby increasing the incomes of
those familiar with the jargon.

As increased on-line communication came to be in vogue, the utility of
the acronym increased, ostensibly for greater communication
efficiency. But they still serve their primary purpose.

I have vague recollections of having fixed similar problems by tweaking
the device ordering in initrd and/or modprobe.conf; however, backing up

Phil,

There are a couple of reasons, although they may make no sense.  First, 
I did not want a multiple point of failure.  If the boot loader is on 
the MBR of /dev/sda, and the os is on /dev/sdb, then you have a multiple 
point of failure.  If either card dies, then I am hosed.  It would be 
*similar* to running a RAID0 on the os.  Not a good idea IMHO.


Also, if I wanted to replace the data drives in the future, I couldn't 
just unmount the partition and replace the drives.  The boot loader 
would be gone as well.


I did not find an option during the install prep to re-locate grub to 
the MBR of /dev/sdb.  I probably should try the text-based installer to 
see if there are more options.


Heck, I may just remove the 9550 board until the initial os install is 
completed.  That should accomplish what I am trying to achieve.  Just 
seems like there should be a more elegant way of doing this.


I am installing 5.1 because I have the isos on hand.  I was just going 
to let yum update me to 5.2...


Thanks for your help,

[CentOS] resize LVM (ext3)

2008-10-29 Thread David Hláčik
Hello guys,

my scenario is following


   1. I have LVM group named system
   2. I have a logical volumes
  - system/root , ext3 mounted as / (20GB)
  - system/swap, swap
  - system/home, ext3 mounted as /home (431GB)

I need to shrink system/home to 80GB (currently there is 57GB used) and use
free space to create another logical volumes.

My scenario is


   1. reduce ext3 fs size to 80GB by using resize2s
   2. reduce system/home size by using lvreduce
   3. create another logical volumes

Questions


   1. How can i be sure that i will shrink ext3 to exact size 80GB and that
   the same will lvreduce do? I do not want to cut from ext3 filesystem if i
   will reduce logical volume too much
   2. Can you please send me commands to achieve 1) and 2) part of my
   scenario?
   3. Or can i just use lvreduce and my ext3 will shrink automatically?
   4. Do i need to umount system/home when resizing?

Thanks in advance!

fssize=$(tune2fs -l $dev |

Now, $fssize has the complete size in bytes. Verify it:
echo $fssize

Now, for lvresize:
lvresize -L 80G system/home

Verify that the printed target size matches the wanted value.

3. Or can i just use lvreduce and my ext3 will shrink automatically?

NO! lvreduce doesn't care about what's inside, and will happily lose
data.

4. Do i need to umount system/home when resizing?

Yes, and you must do a full fsck also:

e2fsck -f /dev/system/home

 Les,

 You can try the version of freenx here:

 (freenx-0.7.3 is there, the NX is same as released version)
 If it all works well, we can release this version of freenx.
 
 Thanks! The i386 version installs OK, works at least as well as the
 previous version and I have been able to connect to a shadow session of
 another freenx session.

Glad that it works, it also seems to work for me on i386 and x86_64.

 However, I think I'm missing something about
 how to connect to a shadowed console session.  If I configure the client
 to use a vnc session, I can see it as vnc-local but haven't been able to
 connect even though I am connecting as the same user.  Do I need to set
 a password for this?  Is documentation for the new features available
 somewhere?
 

I do not know how to connect to a local vnc session using the NX client,
though I was going to look into that.  If I figure something out I will
post here, though I am not sure when I can look at it.

seeing very similar behavior.  It has gotten better since we complained

The fast load on subsequent visits could be explained by Drupal doing 
some caching of needed items so it doesn't have to go to the database.


The initial site load time became much more noticeable after IX took 
some kind of hit on their DB server.  All we know is the site suddenly 
couldn't connect to the database, they fixed something on their end and 
the database came back but we've had the long lag for first load ever since.

From: Scott Silva [EMAIL PROTECTED]

Wrote:

 Even though the recommended swap is 2 times system memory, I have
 never made a swap partition over 2 GB. Maybe I am also flirting

I believe that the current recommendation is 2 x physical memory up to 2
GB and then 1 x physical memory thereafter.

See:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Deployment_Guide/s1-swap-what-is.html

 Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and
then an additional 1x physical RAM for any amount above 2 GB, but never
less than 32 MB.

So, if:

M = Amount of RAM in GB, and S = Amount of swap in GB, then

If M  2
S = M *2
Else
S = M + 2

Using this formula, a system with 2 GB of physical RAM would have 4 GB of
swap, while one with 3 GB of physical RAM would have 5 GB of swap.
Creating a large swap space partition can be especially helpful if you
plan to upgrade your RAM at a later time.

For systems with really large amounts of RAM (more than 32 GB) you can
likely get away with a smaller swap partition (around 1x, or less, of
physical RAM).

[CentOS] how to get rid of kerberos

2008-10-29 Thread Marcelo M. Garcia

Hi

How to get rid of kerberos, or at least to prevent to go into path? 
Where is defined the path for users?


I need to configure and use rtools (I know that I should use ssh, but I 
need rtools) and I think very annoying the messages from Kerberized rsh 
or rlogin, like this:

-sh-3.2$ rsh kitten02
connect to address 192.168.89.2 port 543: Connection refused
Trying krb4 rlogin...
connect to address 192.168.89.2 port 543: Connection refused
trying normal rlogin (/usr/bin/rlogin)
Last login: Tue Jun  3 20:17:32 from kitten01
-sh-3.2$

But if kerberos is not in path, everything works fine:
-sh-3.2$ rsh kitten02
Last login: Tue Jun  3 20:13:13 from kitten01
-sh-3.2$

Thanks

 then an additional 1x physical RAM for any amount above 2 GB, but never

That's a silly recommendation, and never been true for Linux.  RedHat
don't always know what they're talking about.

In older BSD systems (eg around SunOS 4 times or before) swap space was
utilised oddly; all memory was allocated from swap, so you needed _at
least_ physmem of swap just to use all your real memory!  So if you
added physmem of swap then your total virtual memory size was still
only physmem.  No help!  So the rule of thumb came along that said
swap = 2*physmem and that gave you a VM of 2*physmem.   Linux never
did this (and I don't think modern BSDs do, either) so adding physmem
of swap will automatically give you twice physmem of VM.

So the old BSD 'swap=2*physmem' rule of thumb is now a linux
'swap=physmem' guideline instead.

But it's still just a rule of thumb, or a guideline.  How much swap you need
depends on your circumstances and load.  If you have 4Gb of RAM and find
the system is using most of it for cache then you may not even need any
swap!

Reduce the filesystem to 78G or 79G with resize2fs, then reduce the LV
to 80G, then grow the ext3 filesystem again to fill all the LV. This
should make it safer when cutting the LV.

That's what I always do. It eliminates small chances of my math
disagreeing with resize2fs's math. Plus, IIRC, then the second re-size
doesn't need a size parameter. Resize2fs will automatically grow to the
maximum allowed by the partition/logvol.

Re: [CentOS] how to get rid of kerberos

2008-10-29 Thread Tony Schreiner
/usr/kerberos/bin  gets put in your path by /etc/profile.d/krb5- 
workstation.sh  or krb5-workstation.csh.


You can move them or comment them to prevent them from working

or

yum remove krb-workstation

to remove the package.

But you do know that rsh is not safe on an open network right?

[CentOS] Can one invoke multiple INSTANCEs of Firefox on CentOS

2008-10-29 Thread James B. Byrne
I am doing some testing with XForms and I really need a separate instance
of Firefox, one that shares nothing with my primary instance that has
various reference works and web sites open, to test forms.  Is this even
possible?  I have a sense from the small bit of testing that I have done
that even with separate profiles and invoking the firefox process manually
from different terminal windows does not provide a completely separate
running instance on the desktop.

Is there a way to do this?  If so then how?

I fully understand the emotional need to respond to one who throws
around terms like Communist, Tyrannical, etc. even if ostensibly
framed as a rhetorical question. Certain terms and phrases are by nature
pejorative and I;m sure the OP knew this when he entered his post.

My feeling was the OP is either an ignorant, unappreciative,
self-centered, and emotionally immature person that expects all projects
and activities to meet his desires, wants and criteria, _or_ he is
trolling.

In either case, any response you provide will be obviously wasted as the
OP's POV will likely not be affected. Therefore, you waste your time
responding.

[CentOS] Problem with svn/apache

2008-10-29 Thread Joe Tseng
I hope someone can help me with this b/c I'm stumped...  I had set up an svn 
repository a while ago with an apache/webdav front end using the default centos 
packages.  For some reason this morning it stopped working for me - it would 
give me a 403 error.  I suppose the problem is with Apache and not svn.

So far I've checked the following:
I use a couple of files called svn_htpasswd_file (for userids/password hashes) 
and svn_auth_file (users, groups and permissions) - I verified the files were 
still apache:apache and were user-readable
Just for grins I ran chown -R apache:apache on my repository home directory 
and all repositoriesI made a new user entry in the two files listed above with 
full admin rightsI restarted httpd and rebooted the serverI made sure the httpd 
processes were running using apache as userAnd I've run out of ideas.  Has 
anyone else seen this before?

[CentOS] Re: Installer stopped short

2008-10-29 Thread Scott Silva
on 10-29-2008 2:54 PM Niki Kovacs spake the following:
 Hi,
 
 I just tried to install a CentOS 5 desktop on very recent hardware, an
 Acer desktop machine. The installer stopped short very early. I gave
 Ubuntu 8.04 a shot, and it installed without a problem. Now what can I
 do about this?
 
1) Try the RHEL 5.3 Beta and see if it is any better. Report your findings to
the list.

2) See if the manufacturer has a driver disk for the hardware (not likely).

3) Use Ubuntu until 5.3 comes out, and see if it (CentOS) supports the
hardware later.

 Is there a way to use some enhanced kernel (like the centos.plus
 kernel) to perform the install? I guess what's missing there is a
 specific driver for something (SATA drive? Processor?).
 
There are some boot options to try, but you have a good chance that CentOS
won't support your hardware. There isn't any way to use a different installer
kernel without learning how to build install disks with Anaconda. It is not
the most difficult thing in the world to do, but it is not the easiest either.

 Any suggestions?

 I just tried to install a CentOS 5 desktop on very recent hardware,
 an Acer desktop machine. The installer stopped short very early. I

How early is very early? Did it stop before the first Welcome to Centos
screen, or did you get to disk partitioning? Knowing exactly where it
dies can be useful. Also, scan the disc to see if that's naffed and
causing grief.

When CentOS is installing you can press Alt-F2 - Alt-F4 (Ctrl-Alt
if you're in gui mode) and there should be a few different screens of
logs. Do any of those provide insight into where it's failing, or what
it last tried to do?

I know it's going farther off the beaten topic here, but just received
this email of warm wishes from our friend Spike Turner that I thought
I'd share.

It's not even necessary to insult him, he's done it all for himself.

[CentOS] Question re RHEL 5.3

2008-10-29 Thread MHR
I've heard now from more than one source about problems with CentOS
(and RH) at least up through 5.2 w.r.t. SATA drive handling, and I've
even reported on this myself in this list before.

My question is, do we have any idea if 5.3 has any improvements in this area?

One of my cohorts here, who happens to be a Fedora fan, says that
these problems are fixed in F9, but I have grave concerns about
putting an enterprise lifeline main application on any Fedora release.
 If 5.3 solves these issues, I'd much rather go with that.

Any ideas?  Any places I might look to see for myself?

Thanks.

The only issue I've ever seen has been with the onboard fakeraid stuff
more and more vendors seem to be adding. I've been using SATA disks
with centos since the early 4.x days without issue, so you have me at
a bit of a loss here. I'd say if anything it's due to controller
support, and much of that can be chalked up to what hardware vendors
are pawning off as 'controllers' these days.

 Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and
then an additional 1x physical RAM for any amount above 2 GB, but never
less than 32 MB.


That's a silly recommendation, and never been true for Linux.  RedHat
don't always know what they're talking about.

In older BSD systems (eg around SunOS 4 times or before) swap space was
utilised oddly; all memory was allocated from swap, so you needed _at
least_ physmem of swap just to use all your real memory!  So if you
added physmem of swap then your total virtual memory size was still
only physmem.  No help!  So the rule of thumb came along that said
swap = 2*physmem and that gave you a VM of 2*physmem.   Linux never
did this (and I don't think modern BSDs do, either) so adding physmem
of swap will automatically give you twice physmem of VM.


Ah, yes, not an older release of Solaris...SunOS4

A certain release of SunOS4 required swap be twice the amount of RAM or 
it would crash according to an article that I read but I cannot find 
right now. Here is a FAQ article related to SunOS that tells us how 
SunOS4 handled virtual memory (swap must be at least the same amount of 
RAM): http://www.bjnet.edu.cn/sun-admin/FAQ/F-comp-sys-sun/Q30-0.html


The source of this 'recommendation' that swap be twice that of RAM is 
affects more than just Linux


http://blogs.sun.com/jimlaurent/entry/solaris_faq_myths_and_facts

So please, stop spreading this swap should be twice the amount of RAM 
installed nonsense.

No, and from what I saw on the RH bugzilla list of SATA disk related

I will go back and dig deeper.

Re: [CentOS] changing partition priority on install

I did not find an option during the install prep to re-locate grub to 
the MBR of /dev/sdb.  I probably should try the text-based installer 
to see if there are more options.


It is there in the GUI installer - can't remember exactly where without 
going through the install, but something like an Advanced button on a 
configuration page toward the end of the process.


Heck, I may just remove the 9550 board until the initial os install is 
completed.  That should accomplish what I am trying to achieve.  Just 
seems like there should be a more elegant way of doing this.


I am installing 5.1 because I have the isos on hand.  I was just going 
to let yum update me to 5.2...


That should work.


Thanks for your help,

Phil,

Thanks for your input.  I did find the location of the grub install 
modification.  Strange thing is, when I restarted the install, grub 
defaulted to the MBR of /dev/sdb.  I did not change any hardware or bios 
settings in between attempts.  I have no idea why the change happened.


Once the install was completed, the OS partition showed up as /dev/sda, 
even though it showed up as /dev/sdb during the installation process. 
Grub is apparently happily residing in the MBR of /dev/sda.  Again, I 
can't explain it.


If you (or anyone else) has insights to this behaviour, or can point me 
to where I can read up on it, I would appreciate it.


Thanks again for all your help.

The one problem I've seen and posted here was w.r.t. smartd error
reports showing 2^32 - 1 errors on one of the disks (probably my
system disk) every few minutes.  I thought this was more than just a
bit suspicious, since there are only 4,687,500,000 sectors on a 300GB
disk, and the likelihood of having errors on 4,294,967,295 (~92%) of
them is rather slim unless the whole system is crashing a lot (it's
not).  It's a Seagate 300GB, so I ran Seagate's SeaTools on it in
lightweight mode, and no problems were reported, which is good because
the disk is only about a year and a half old and has my CentOS root,
swap, boot and home partitions on it.

I'll dig deeper on this one - sounds fishy to me, too, now

I recently set up a CentOS 5.2 server with RAID 1 (software) and 2 sata

old codger hat  this was also how early IBM System/370 DOS/VS

now, on late model Solaris, 'swap' is also used as tmpfs, which /tmp and 
/var/run utilizes by default, so you definitely want to allocate 
sufficient swap space for this at least, regardless of how large your 
physical memory is.
