dd over ssh should be a sure thing.  If you do a lot of image copies remote or 
otherwise you might want to try clonezilla-live.  It knows enough about most 
file systems to only copy the used blocks and can access the image store with 
smb, nfs, or ssh.

cmd to push the image from the remote server using ssh into the local pipe

Correct. However if you wish to implement the client upload feature, 
there is an uploads directory under wp-content which will need write 
ability. The WordPress created subdirectories within this directory will 
also be set to these permissions. But that is only place where write 
should be considered. This is where items like uploaded photos exist.

[CentOS] postgresql copy to and selinux

[Marcelo Roccasalva]

I need to run a "copy table to '/home/user/dir/copy.txt';" but I get
permission denied. Filesystem dir modes are ok and I get no event
logged in audit.log, but if I setenforce 0, I can do the copy. This
explains auditd silence:

# sesearch --audit |egrep postgres.*home
   dontaudit postgresql_t user_home_dir_t : dir { getattr search };
   dontaudit postgresql_t home_root_t : dir { getattr search };

I changed the "dir" type to tmpfs_t and I could write with "\copy" but
not with "copy".

Anyway, what are the best practices to allow postgresql "copy to" a
subdirectory of a home directory (without disabling selinux)? I'm
running centos 5.5.

before picking an operating system for the central server, its a good 
idea to pick the Point-of-sale system architecture.

using terminal server/citrix/nx/etc type connectivity for POS from 
remote locations means if the network is down, the cash registers are 
down.  thats not good. most POS systems have a local onsite store 
server at each location, the registers are terminals to this server, but 
usually run the cash register POS software directly, then the store 
server communicates with the corporate mothership as needed, either live 
or batching transaction logs as appropriate.

different sorts of retail businesses have widely varying POS 
requirements, for instance, the POS system for a restaurant chain is 
very different than the one for a auto parts chain.

All these questions should be sorted out long before getting into 
implementation details like operating systems, hardware platforms.

I think you're reading into this too much.

It sounds like their running an old serial or X terminal server based on 
SCO/HPUX or something and they are thinking of going to a Windows based 
terminal server.

For a small company I'd probably suggest MS terminal servers, running under ESX 
on big hardware so they can provision them out over time.

Seems to me, though memory is hazy, that I was able to get around this
by going in and changing boot order--that is, in the advanced grub menu.

I think there may be differences in controllers and possibly in failure 
modes as to whether the 2nd drive becomes seen as the first when the 
first one fails.  But I'm not sure how to know this ahead of time or the 
right syntax to use for each case.  And while the md devices will still 
build out of the right pieces when they autodetect, you may also need to 
adjust anything that uses the /dev/sd? names to account for them 
shifting (or not) and be aware of it in any manual setup commands like 
using mdadm to force partitions to be added if they didn't come up 
automatically.

Is there an error message before it "aborts"?
I use a kickstrat so I am not sure but, I think you should not be prompted for 
the iso location...
Did you add "method=hd:sda2:/centos" in syslinux.cfg?
It specifies the location of the ISO image(s).
If you are in a hurry, use the alternative methods (see Alternatives at the

Yeah - that may be either an install thing, or an anaconda one. I hate
that. I always have to reboot from the USB key, go to linux rescue, then
chroot to /mnt/sysimage, and grub-install /dev/sda

Then I have to edit /boot/device.map, and hand-make an
/boot/grub/grub.conf. I keep meaning to have one on the USB key, so I can
just copy it after I do the grub install.

Re: [CentOS] Building an install disk on a USB key manually or using unetbootin

I was able to successfully install CentOS 32-bit from an 8GB USB flash
drive (4GB is not quite big enough, even for i386) created with this
procedure:

Create a 10M DOS partition on the USB drive and make it active
Create Linux partition using the rest of the drive

mkfs -t vfat /dev/
mkfs /dev/

liveCD-iso-to-disk  /dev/
mount /dev/ /mnt
rsync --progress  /mnt/

You can get the boot.iso by loop-mounting the CentOS iso and pulling it
out of the /os/i386/images directory, or grab it from one of the mirrors
(the mirror links on the CentOS site link directly to the install isos,
so you'll have to browse up a few directories and then go back down to
find the images directory).

I used 'rsync' here because I hate having a copy process run for 10
minutes with no progress indication.  :)

The only problem I found was that the install insisted on installing
grub on the USB drive rather than the target hard drive.  I finally had
to skip the grub installation and install it by hand afterwards.

Re: [CentOS] Building an install disk on a USB key manually or using unetbootin

[David]

I actually did follow this as the manual attempt at getting it to work; 
unsuccessfully.  I probably should have clarified it better in my 
original email.

The USB boots, I get the install menu, the USB drivers, etc. are 
installed and then I am prompted for the location of the iso.  Once I 
select the location and then the actual iso, the install aborts.

Re: [CentOS] install on raid1

[Jussi Hirvi]

I don't have a direct answer to your question, but here is the howto I 
have been using twice, with good results:

http://www.howtoforge.com/software-raid1-grub-boot-fedora-8

After installing grub to the other disk, did you update your grub.conf 
accordingly?

His syntax shows the installation from within a grub prompt which is right,
Yours looks more like what you use with grub-install. Regardless, his approach
is how my kickstart has been doing it for years with success...

It sounds like you might not have your php set up correctly in apache or 
at least in this virtualhost.  Somewhere in your configuration do you have 
lines that say:

AddHandler php5-script .php
AddType text/html .php

This is most likely found in /etc/httpd/conf.d/php.conf

That did the trick!

I took a peek in /var/log/httpd/error_log, and found a few lines of 
"script tried to increase memory_limit to  bytes".

I edited /etc/php.ini and increased the memory limit from 16M to 32M, 
restarted Apache, and now everything works.

By the way: I wonder if this could create some problems.

[CentOS] Problem installing WordPress on CentOS

[Niki Kovacs]

Hi,

I have a curious problem installing WordPress on a local LAMP server 
running CentOS 5.5. I have some other (dynamic) websites running on the 
same machine without problems. Here's what I did.

1) Create a 'wordpress' database in MySQL monitor.

2) Download WordPress, unzip it into /var/www/html/

3) # chown -R apache:apache /var/www/html/wordpress

4) Open Firefox on http://localhost/wordpress

5) Follow instructions (fill in database name, database user and 
password, etcetera).

And here's where things go wrong. When I click on "Begin installation", 
Firefox wants to "open" the file install.php by leaving me one of the 
two following choices :

a) edit "install.php" in GEdit
b) download "install.php"

I'm puzzled. Why doesn't install.php simply open as a page?

Any idea what went wrong here?

Cheers,

Niki

Well, as I was trying to say, I can transfer in both directions as long 
as I initiate from the computer. I'm assuming this implies everything is 
just fine with the bluetooth unit itself.

It's built-in Bluetooth, by the way.

You know, now that you mention it, I remember that I had to upgrade to a 
Fedora package even to get the discovery stuff and/or connection *from* 
the computer to work (this is something I set up a year or so ago.) I 
installed only bluez-gnome earlier, though, but now I've upgraded the 
other packages, too, so I have the same versions as you. Unfortunately, 
there is still no luck sending from the phone - the behaviour is still 
the same.

Another clue, though: If do the Bluetooth setup in a slightly different 
way on the phone, I get the following messages:

Getting service list...
Service not found

I suppose this may be the root of the problem, i.e. that the phone 
expects the computer to publish a list of services, and the GNOME 
bluetooth stuff doesn't.

Yes, send and receive files by bluetooth, under CentOS 5.5 with a SE
T630 phone and the following setup:
# rpm -qa | grep blue
bluez-gnome-0.8-2.fc7

It works for me since replacing some of the original CentOS packages
with packages from Fedora Core 7 (fc7).

Thx for all the answers.
As a matter of fact, while my Dell Vostro 410 was getting 3.3GB without PAE,
a new Vostro 430 was getting only 3GB (but a full 4GB in PAE)...
I went anyway for the non PAE just for peace of mind and because 3GB is still 
plenty.

[CentOS] Sending files from mobile to CentOS via Bluetooth

[Toralf Lund]

Has anyone here managed to send files from a mobile phone to a CentOS 
system via Bluetooth? I'm trying with a Samsung E1310, using the GNOME 
tools, but can't get it to work. I can send files from the Linux box to 
this phone using the Nautilus bluetooth plugin 
(nautilus-sendto-bluetooth), and have also managed to "pull" some data 
I've been trying to send, via "obexftp". If I try to initiate a transfer 
from the phone, however, it will just display a generic "connection 
failed" message. If I run gnome-obex-server from the command line while 
doing this, I get

$ gnome-obex-server
conn_request:   bdaddr 
conn_complete:  status 0x00

But that's pretty much it. Any ideas? I'll also include some hcidump 
output below... Note that based on a simple web search, it does look 
like others have experienced the same thing, but I didn't really get 
much out of the information I found in terms of figuring out how to 
resolve the problem.

I'm using the latest packages from the CentOS 5 repositories. I also 
tried slightly older versions of bluez-utils and blues-libs as report at 
Red Hat Bugzilla suggested this might help, but it  didn't really.

Either you can do most of it "manualy" (and learn a few things), 
or you use others scripts/programs (seeAlternatives at the bottom)...

[CentOS] install on raid1

[Wessel | Postoffice]

Hi All,

I'm currently trying to install centos 5.4 x86-64bit on a raid 1, so if one the 
2 disks fails the server will still be available.
i installed grub on /dev/sda using the advanced grub configuration option 
during the install.
after the install is done i boot in linux rescue mode , chroot the filesystem 
and copy grub to both drives using:
grub>root (hd0,0)
grub>setup (hd0)
grub>root (hd1,0
grub>setup (hd1)
grub>quit

then reboot, but is still get the error : disk boot faillure, insert linux 
install disk.
does anyone now what i'm doing wrong? here is a copy of my partition scheme.

Disk /dev/sda: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

?

Re: [CentOS] Fsck on mdraid array - SOLVED

[Jussi Hirvi]

Hei,

Ok, as many of you pointed out, the raid arrays did not start 
automatically on "linux rescue" boot (when not mounting the arrays).

I followed Mogens' advice: I let linux rescue mount the arrays, then 
checked /etc/mtab and unmounted everything. After that fsck run ok.

(Turned out the filesystems were ok, so my problem must lie elsewhere.)
