Re: [CentOS] NIC recongized but cant ping

[mechy2k2000]

No, the way the server is planned be setup certain NICs go to different ip
subnets. I got it working though after making virtual bridges for each nic
and using only one for the host and the rest for VMs. Once it got working I
did not try to reproduce the issue.  I will in the future keep these things
in mind should the issue come up again.

Thanks

ON Centos 5, using GPARTED I created partitions for filing systems ext3
and ext4. 4 primary and unlimited (except by space) extended partitions.
That suggests those partitions are not GPT but old fashioned M$DOS

I encrypted some of those partitions.

The 'blkid' command produces a list of UUIDs for those partitions.

A few examples:-

If it is old fashioned MSDOS, you can have four total primary and extended,
not four primary plus extended.  An extended partition then provides a
container for further logical partitions.

LUKS provides a UUID, so being encrypted isn't a barrier to having a UUID.

Yes you are correct. Maximum 4 primary or maximum 3 primary and 1
extended which is then sub-divided into more partitions.

But my point was M$ DOS partitions, not being GPT partitions, can have
UUIDs. The original poster appeared to suggest that was not possible. He
wrote

When I think I am mounting a M$ DOS partition, am I mounting a real
partition or merely 'the file system' within that partition ?  Some may
think one can't have one without the other.

No, the partition there does not have a UUID.  Run fdisk, create a partition,
dd if=/dev/zero of=/dev/sda4

blkid

You'll see no UUID, as the partition does not provide a UUID, and there's
nothing on it to provide a UUID.  Format it, or make some swap space or
whatever, and you get a UUID.

You never mount a partition, only a filesystem.  The partition merely points
you to where the filesystem is.

Those were filesystem UUIDs not partition UUIDs ...

LUKS has its own header similar to ext4, lvm, etc headers which has a UUID
in it.

This UUID being associated with the LUKS header indicates it is not a
partition UUID.

A dd of this (or lvm snapshot) to another partition will keep the same UUID.

A partition UUID within a GPT table would not be persisted in this manner,
and msdos labeled disks have no concept of this to begin with.

Of course you can have a partition or filesystem without the other. This is
how raw devices work and you can mkfs a block device with no partitions.

When you mount something you mount the filesystem.

Please check your SATA data cable first, I have similar experience where
something was
wrong with the cable and it started to give DRDY errors. When I put that
disk into another
machine then it was working fine without any problem.

Try to boot with SystemRescueCD and see that you can mount those LV's.
If that thing does not works then look for any File-System errors.

It's something to consider... but I can't do that easily. This is a server 
that's been running for years, and is in use, and it's a hot-swap bay.

Then it also could be caused by a micro crack on a backplane.

[CentOS] NUX Skype for Linux

[James B. Byrne]

I had cause to install the Skype for Linux package from the NUX repo. 
I discover that this package is configured to automatically start
Skype whenever one logs on to the Gnome desktop.  This behaviour I do
not wish.  However, there seems to be no option in Skype to turn that
'feature' off. Is there any way to disable this in Gnome or elsewhere?

I will be removing Skype shortly when the present need for it passes
but I do not wish this thing automatically starting in the meantime.

Yes you are correct. Maximum 4 primary or maximum 3 primary and 1

LUKS provides a UUID, so being encrypted isn't a barrier to having a

But my point was M$ DOS partitions, not being GPT partitions, can have

LUKS physical volume UUIDs, actually. When you create a LUKS logical 
volume within that PV, it also has a UUID, and a filesystem within that 
LUKS LV will have its own UUID. These are all part of the partition's 
_content_. A GPT partition has its own UUID, independent of the 
partition's content. An MSDOS partition does not.



LUKS has its own header similar to ext4, lvm, etc headers which has a UUID
in it.

This UUID being associated with the LUKS header indicates it is not a
partition UUID.

A dd of this (or lvm snapshot) to another partition will keep the same UUID.


Indeed. If your version of cryptsetup is new enough (supports the 
"--header" option), try doing the luksFormat operation with a detached 
header. Now you will find that your LUKS partition no longer has a UUID.



A partition UUID within a GPT table would not be persisted in this manner,
and msdos labeled disks have no concept of this to begin with.

I obviously had LVM on my mind when I wrote that. Sorry. The principle still

[CentOS] selinux allow apache log access

[Tim Dunphy]

Hey guys,.

 I have a centos 7 machine I'm using as a zabbix server. And I noticed that
apache won't start, with this complaint in the error log:

(13)Permission denied: AH00091: httpd: could not open error log file
/var/log/zabbix_error_log.
AH00015: Unable to open logs


I tried having a look at audit2allow and this is the response I get back:

[root@monitor2:/etc/httpd] #grep http /var/log/audit/audit.log | audit2allow


#= httpd_t ==
allow httpd_t zabbix_log_t:file open;

How can I turn that bit of information into a rule that allows apache
access to this zabbix log file?

I notice that if I disable selinux using setenfor 0, apache starts up
without complaint. But I would rather not leave it disabled.

Thanks,
Tim

[CentOS] gvim current directory

[Michael Hennebry]

When I gvim a file from gnome,
gvim's working directory is always my home directory.
That is not what I want.
It is inconvenient for :vi , :r and :w something.else .
Is there a way to automatically cause gvim's current
directory to be the directory of the edited file?
I am aware of workarounds involving the command line.
I am aware of gedit.
I am looking for a way to give gvim the correct working directory.
Is this a gnome thing?

Hi,

   I'm using unison (http://www.cis.upenn.edu/~bcpierce/unison/) to do this.  
It can
sync in both ways if files are changed on both sides between syncs.

   And, IMHO it's better to filter out the directories that contain 
configuration
for the systems, or better, sync only the documents and other pertinent files.

   Att.,

 Antonio.

It was working fine before I put in the 3TB drive earlier this year, and I
haven't had any trouble at all with it until yesterday, when I started
copying a lot of data to a not-much-used disk.

No, it's not a GNOME thing.  I assume you're opening up gvim from a
menu?  Then your current working directory is $HOME.  That's the way
unix/linux works when you start a program and your CWD is $HOME.  The
graphical interface has a CWD of $HOME, so anything it forks will
too.

i did not recognize the site, but when i connected to it and started
to bookmark it, i saw that i already had it bookmarked.

in checking, i found that it was from 2009-0514-09:08 pm when i ran
a search for backup and recovery sites.

i pulled the docs and tar file to check out later.

i agree, and i have already started writing scripts for both desktop
and laptop to sync just the common, _non_unique_ directories and files.

so, back to my original question, worded differently.

what directories and files should not be copied so that configs for
desktop/laptop do not corrupt configs for laptop/desktop screen?

i am presuming that '.KDE' is one of them, and what else?

i can got thru all directories and files, which would take time and
is what i am wanting to avoid. call me lazy. ;-)

Maybe you need to be clearer.  The screen's configuration is not
really configured in your home directory, but by X (although these
days it's all autoprobed).

Are you talking about what icons appear?  The configuration for KDE?

 Please check your SATA data cable first, I have similar experience
 where something was wrong with the cable and it started to give
 DRDY errors. When I put that disk into another machine then
 it was working fine without any problem.

Then I would agree, cable is much more like reason than (microcrack in)
backplane. Cable may have just marginally insufficient bandwidth, whereas
microcrack effect is usually (but not always) "more fatal".

Does drive plug in into connector nice and smoothly, and tray moves into
hotswap bay smoothly? When you plug the drive, you usually can feel when
connector plugs in, and drive usually moved further in more than 1/16 of
an inch (or more than 2 mm). This is usually sufficient for good
connection.

How about sticking drive into different machine and trying to mount
filesystem there? Any Linux workstation you have around may do.

The last of wild guesses: could it be that the PS of the box in question
is marginally insufficient in power? This tends to show up on machines
that run well for years even if you didn't change anything, and the reason
maybe one of two: electrolytic capacitor loose to some extent their
capacitance with age, and hard drive with age start drawing more power.
Could your new big drive push your box in that direction?

Good luck!

Proxmox is is debian based, but has a really good web based user
interface. I use it to host my CentOS VMs and containers. I would be
aware that it uses 2.6.32 and I have run into hardware issues. (Mainly
issues realtek ethernet adapters, I suggest using Intel adapters)

also, thank you for kicking my chemo brain in the butt. ;-)

yes, i forgot about X being the wise and wondrous now.

iirc, there used to be a file under /etc/X11 that had specs for
keyboard, mouse, graphics card, monitor, language, etc, that one
could make custom changes to if needed. several years back that
got changed with auto probe. yes/no?

therefore, my only real concern would be for progs like firefox,
thunderbird and what else that is not standard with distrib, and
have special files in /lib, /lib64, etc. y/n?

as for icons and KDE configs, icons should be same as they are
under /usr/share and i do want to have same/similar desktop window
settings.

long story to short, just try it. y/n?

I have a fairly complex pxe configuration... Multi-distro/OS  Here is my centos 
pxelinux.cfg/default:

# Centos 3.9
label centos3
  kernel centos/3.9/vmlinuz
  append initrd=centos/3.9/initrd.img ramdisk_size=10 text ks=http:///ks.cfg

# Centos 4.8
label centos4
  kernel centos/4.8/vmlinuz
  append initrd=centos/4.8/initrd.img ramdisk_size=10 text rescue 
ks=http:///ks4.cfg

# Centos 5.5
label centos4
  kernel centos/5.5/vmlinuz
  append initrd=centos/5.5/initrd.img ramdisk_size=10 text ks=http:///ks5.cfg

# Centos 6.4
label centos6
  kernel centos/6.4/64/vmlinuz
  append initrd=centos/6.4/64/initrd.img ramdisk_size=10 text 
ks=http:///ks/ks6-64.cfg
#  append initrd=centos/6.4/64/initrd.img ramdisk_size=10 text 

My kickstart is loaded via http, so you also have to configure the web server 
to be able to serve that as well.  The path for the kernel and initrd is 
relative to the root of the
tftp server.  In my case /tftpboot contains

centos//<32|64>/

with the appropriate kernel and initrd

The real "trick" is building menus.  That is quite poorly documented

Let me know if you need more help.

hope it helps

Thanks for that. I have the laptop running now and am logged into a
virtual console.

dmidecode details for my laptop:

BIOS Information
Vendor: Dell Inc.
Version: A21
Release Date: 11/14/2013

System Information
Manufacturer: Dell Inc.
Product Name: Latitude E6420
Version: 01

Base Board Information
Manufacturer: Dell Inc.
Product Name: 032T9K
Version: A02

I might try downgrading the BIOS version to see if that helps. I don't
know that I've tried doing that with Dell's utility before, but I'll
give it a shot.

I setup a short loop to append the output of /usr/bin/sensors to a log
file and then call 'sync' just after.

This is the last entry just before the system shut down:

Looks like the system is a bit warm, but not overly so? So far I've not
figured out how to check the fan speed. I'll keep looking.

The most common issue with E6 series laptops is dust/lint/hair in the fan
grill.

The bios fan control is based on an efficient extraction of heat, but a
small amount of lint will keep it heatsink warmer longer.

That is the tell tail sign, as it is not cool when under low to no load.

Force the fan to high (dell diagnostic CD or other program) should be strong
(moves an empty paper coffee cup) cold air blowing.

Good tip, thanks.

I tried using the onboard Dell diagnostics and it shows that the current
Processor Fan speed is about 2906 RPMs. It _did_ click loudly once and
then appeared to pick back up. Attempts to run the test aren't yielding
any high spin up/down noises like I'm used to hearing from other systems.

Current thermal readings (inside of the diagnostics screen):

CPU Thermistor: 65C
Ambient Thermistor: 27 C
SODIMM Thermistor: 39 C
Video Thermistor: 54 C

Back on the topic of the diagnostics, I'm running a CPU stress test and
the CPU Thermistor has grown to 69 C.

After some time the fan speed has finally increased to 3257 RPM and I
can finally clearly hear that it is spinning. Once the test completed
and the CPU temp started dropping, so did the fan speed, finally
settling back to about 2900 RPM.

I'm still puzzled why the laptop appears to lockup when attempting to
login to the desktop environment when using CentOS, but not Ubuntu
15.04. Any thoughts there?

Back on the topic of CentOS, I ran 'watch /usr/bin/sensors' for about 20
minutes and the temp only slightly fluctuated. It was only the login
attempt that shut down the system.

No, not really.
Aren't the GUI's the same irrespective of the OS?

I copy-pasted the setting steps to not have Skype autostart from a 
Windows-centric page, and I'm assuming the GUI, and should therefore be the 
same.

If it'll make you feel better, please replace all instances of "Windows" above 
with "CentOS". ;-)

Re: [CentOS] Virtualization

[Alessandro Baggi]

Please don't top-post with fully quoting all previous content. This is a
mailinglist.

Proxmox VE is based on Debian. What does this have to do with CentOS? As
it makes use of KVM you can run CentOS on top of it as a virtualization
guest.
