 Saludos Co-listeros.

 Hemos comprado dos servidores Hp Proliannt DL360 g6, estos equipos vienen
 dotados con dos NICs Broadcom netextreme II Gigabite, que no son reconocidos
 por Centos al momento de instalar.

 haciendo un listado de los modulos instalados con el comando lsmode me
 muestra el modulo bnx2 que hacen referencia al modulo para esta NICs, por
 otro lado ejecutando el comando lspci me muestra info de las nics. he
 descargado e instalado los drivers desde el sitio de BroadCom, he
 configurado los parametros de red respectivos y aun no consigo levantar
 estos dispositivos.

 he probado con la ultima version de Centos (5.5) tanto para 32bits como de
 64 bits sin ningun resultado.

 agradeceria desde ya cualquier ayuda o sugerencia (menos cambiar los
 servidores jejeje) que me puedan brindar para poder resolver este problema.

[CentOS] Issue with HP Officejet 6500 on CentOS 5.5

2010-09-19 Thread Mark
I just picked one of these up to replace my 4315, which broke (I think
the feeder roller gear broke from an overstuffed feeder), but it's
giving me problems.

I had no trouble configuring it to print, but it doesn't appear in
lsusb and xsane can't find it, so I can't scan with it, which is the
main reason I bought it in the first place.

I've tried restarting the autofs service (automounter), rebooting, and
switching the USB cables with my old HP Scanjet 3300C, but the 3300
shows up on either cable and the 6500 doesn't appear at all.

I checked in Google and saw other issues with the 6500, but this
wasn't one of them.

Any suggestions?

I suppose I could get a switch and hook it up via Ethernet, but that
really isn't a good solution, and it doesn't explain the problem.

Thanks.

Yeap my Scan Jet was the same way.  It printed but would not scan.  I
got the HP Open Source drivers and installed them and was no problems
after that.

Well their instructions are off. Their rpm will not install because of
dependencies and file ownership conflict between rpms. To succeed at
installing their hplip rpm, I had to provide the --nodeps argument to
remove hpijs. Otherwise, uninstalling hpijs would remove some packages
required packages by hplip-3.10.6_rhel-5.0 and reinstalling the
requirements would bring back hpijs.

As for setting selinux to permissive, I didn't bother. I'm sticking to
enforcing. I'd rather fix selinux when I'll need a blocked feature than
disabling it. For the record, here's the avc:

avc:  denied  { write } for  pid=23972 comm=hp name=.index dev=dm-4

It didn't prevent me from printing but I have not tried scanning.

NX authenticates as the nx user via ssh keys to get an encrypted connection to 
pass the real user credentials over.  The commercial NX server always uses the 
same key as the client, but freenx (at least as packaged in epel or 
centos-testing) generates a unique key per install.  So you have to get the 
contents from /etc/nxserver/client.id_dsa.key into the client config for each 
target host.  You can do this by copying the file with winscp and importing it 
with the NX client gui  Click the 'configure', then the 'key' buttons to get to 
the right place.  Or you can use putty, cat the file to get the text on the 
screen and copy/paste it into the dialog box, replacing what is there - keeping 
the ---begin and ---end lines.

 I'd really like to see a CentOS - NX configuration guide but couldn't find 
 one.
 Can someone just tell me how this should be configuredwhat changes do I

It should come up working - but you can copy the node.conf.sample to node.conf 
and edit it and/or run /usr/bin/nxsetup again if you want to change any options.

 ssh (putty and WinSCP) works just fine for me in case you need to know.
 If you need any particular information, please let me know.

These connect directly as the user - for NX, you need an nx user that should 
have been installed by the package.

Looks like you can get a lot of AVCs. My guess is it depends on how you
installed the printer. The avc above was from a printer installed with
hp-setup. But I get a lot more from an old printer entry that I updated
its make/model and URI.

The OP asked this question on CentOS forums:

I referred him to the CentOS wiki at:

http://wiki.centos.org/HowTos/FreeNX

Then it turnes out he is using NX from Nomachine.  There are
differences between the Nomachine version and CentOS' nx/freenx as you
pointed out.

 I'd really like to see a CentOS - NX configuration guide but couldn't find 
 one.

[CentOS] GRUB woes: GRUB Hard Disk Error

2010-09-19 Thread Rob Del Vecchio
Hello all,
I am attempting to install CentOS 5.5 on a recently donated home server (was
Windows).  I've tried installing twice; first, separating /boot, swap, /,
/var, /usr and /home into different partitions, the second time choosing
default layout.  Both times have resulted in GRUB Hard Disk Error upon
boot.

About the hard disk, it is a Seagate SATA drive.  I do not have another
drive to configure RAID.
The BIOS is set to:
Onboard PATA/SATA Adapters = Both
SATA mode = IDE
Onboard PATA/SATA Cofiguration = Enhanced Mode (???)

Upon booting into rescue mode, the file systems mount successfully and I am
able to read data from files.
The current file structure is (default layout):
/boot
/
swap

grub.conf:
#boot=/dev/sda1
default=0
timeout=5
splashimage=(hd1,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-194.el5)
   root (hd1,0)
   kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/VolGroup00/LogVol00
   initrd /initrd-2.6.18-194.el5.img
title Other
   rootmoverify (hd0,0)
   chainloader +1

This is brand new from the installation.

My questions are, what am I missing?  Bad configuration?  Should
boot=/dev/sda1 really be commented out?

Some pointers for manually installing and configuring grub would be great,
as I am lacking experience in that area.

Any idea as to what is going on would be great!

Thanks in advance,
Rob

I have selinux disabled.

I was able to plug the 6500 into my son's WinXP box and it worked
there, but I'd SO much rather use xsane than the scanner's control
panel - it's god-awfully slow, and windows takes almost as long as the
scan process itself to finish processing the PDF, and I don't get the
individua page images from multipage scans (like xsane provides).

I used the same USB cable for both host connections, and I've switched
connections on my host between the two open USB ports and neither one
works (although they work just fine for all my other
semi-permanently-attached USB devices, mainly my Brother laser printer
and the old HP Scanjet (and the HP Officejet that broke - it still
recognizes that when it's plugged in, but the scanner refuses to
work).

Any other ideas?  What am I missing?

Well I'd wipe the drive clean using Gparted with a cross 
format. Do a minimal kickstart installation to install GRUB 
on the MBR.

Prior to that make sure the BIOS settings are OK for the 
SATA drive.

That shouldn't take to long.

It decreases performance and could be problematic.

 Well I'd wipe the drive clean using Gparted with a cross
 format. Do a minimal kickstart installation to install GRUB
 on the MBR.

 Prior to that make sure the BIOS settings are OK for the
 SATA drive.

 That shouldn't take to long.

[CentOS] How to simulate minimal ISO install using stage2 image file?

2010-09-19 Thread Chad Woolley
Hello,

I'm working on a project which automates creation of EC2 AMI images.
To do this, you must use a running EC2 instance to mount an image file
in a chroot jail.

My problem is that I want to create an AMI that looks exactly like a
minimal (nothing selected) install from the CentOS ISO image, but the
stage2 image [1] file is much more minimal than that.  e.g., it
doesn't have yum, groups, devices, networking, etc set up as you would
if you had run the ISO minimal install on a real or virtual box.  I
can't mount the ISO directly in the chroot (as far as I know, but I
could be wrong).

My question is, how can I make the mounted stage2.img chroot jail look
just like a minimal ISO install?  I could manually create everything
(which I have started), but this is a lot of work, and I'm likely to
miss something that an ISO build would have (e.g. some group).

Is there some other standard CentOS script I can run after mounting
the stage2.img which will do everything the installer does?  Can I run
the installer manually with some kickstart script?  Pointers to
references and documentation are welcome...

Thanks,
-- Chad

I've read a bit on kickstart installations, and now I get to delve deeper
 :)
Thanks for the advice!

 Can't you put the SATA drive on native instead of IDE in your bios ?
 It decreases performance and could be problematic.

Quite right, all of the information that I found on the grub error paired
SATA and RAID.
I chose this because I wanted to remove the variable of a RAID installation.
 In retrospect, that was an unfounded idea.

Thanks,
Rob

Also please note that if that card has SATA 2.0 capacity, native mode is
probably named AHCI on the bios.

Indeed!  There is an AHCI option.  I will set that.

Re: [CentOS] GRUB woes: GRUB Hard Disk Error

2010-09-19 Thread Rob Del Vecchio
Used a kickstart script to install the system, got slightly different
results.
Upon boot, I see:
L 99 99 99 ... 99

and so on.  This could be due to a correctly configured BIOS (set to AHCI).

However, the installation boots when the installation disk finds an
installed copy of CentOS on the hard drive?  For the moment, I am carefully
fiddling with grub.

Sorry, should have googled before mailing; looks like it can be fixed with
grub-install.  Hopefully smooth sailing from here.

Thanks for the help thus far,

[CentOS] Using Make in frequent cron job

2010-09-19 Thread Kenneth Porter
Is there a way to get Make to be silent when it does nothing, but have its 
normal verbosity when something is made?

I want to use Make in a frequent cron job (every 1/2 hour, perhaps 10 
minutes) but I don't want to get a bunch of emails telling me nothing was 
done (which will be most of the time). I just want to know when it found 
something to do.

You can write a wrapper script and run it in a subshell to capture the
output.  Pretend echo is make:

a=$(echo 'made something') # no output
if echo $a | grep 'made something'  /dev/null; then
  echo $a
fi

you could run `make -q`, then if it returns a non-zero status, run `make`


like...

 make -q || make

However, I'm unsure exactly which of those options to use.  This seems
like a common task - are there any good tutorials which show the exact
process to create an basic CentOS image in a chroot via kickstart?
