Libcurl.so.3: wherefore art thou?

Gilbert Sebenste — 2013-05-24T21:07:52

I am utterly stumped. I need libcurl.so.3 for CentOS 6.4.
I have Googled everything and I  have been going all over the Internet 
looking for a solution. I give up; I need help. The error message I
get when I try to run a program is:

error while loading shared libraries: libcurl.so.3: cannot open shared 
object file: No such file or directory

I have:

Package libcurl-7.19.7-36.el6_4.i686 already installed and latest version
Package python-pycurl-7.19.0-8.el6.i686 already installed and latest 
version
Package curl-7.19.7-36.el6_4.i686 already installed and latest version
Package libcurl-devel-7.19.7-36.el6_4.i686 already installed and latest 
version

I also have git installed (yes, I know about the EPEL conflict giving 
me a 5.9 version) and I do have the CentOS 6 version installed)...no 
dice. Can anyone help me?

Gilbert

Failed to create /dev/loop0p* entries for partitionsinside loopback devices

Gelen James — 2013-05-24T17:56:21

centos 6 failed to create entries under /dev for newly created loopback devices. Any one know why? and how to fix/workaround it?

The steps to duplicate is pretty simple

dd if=/dev/zero of=/tmp/deleteme bs=1M count=100
losetup /dev/loop0 /tmp/deleteme
fdisk /dev/loop0   ## created partitions 1, 2, etc.
fdisk -l /dev/loop0  ## confirmed that the partitions do exist
mkfs.ext3 /dev/loop0p1 ## failed here, the error prompt says that the /dev/loop0p1 doesn't exist!
ls /dev/loop0p*  ## no entries

Please shed a light here, I'm running centos 6.4

Thanks.

CentOS 6 and PHP

Glenn Eychaner — 2013-05-24T15:42:15

Still upgrading CentOS 5 to CentOS 6, and have run into the next issue:

When I install httpd and php, everything works great, and the default-test "<?php phpinfo(); ?>" works great.  The problem is that I have a bunch of old HTML that seems to use "<?" alone (or worse, "<!--?"), which worked in CentOS 5 but fails in CentOS 6.  I can change all the HTML, but is there an easier way?

Summary of previous issues:
system-config-network-cmd leaving behind "ifcfg" files in network-scripts that it shouldn't: I still don't have an answer for this one; I work around it by naming all the scripts "ifcfg-ethX_<profile>" and cleaning any that don't match <profile> after running system-config-network-cmd.  I suspect it has to do with either the contents of /etc/udev/rules.d/70-persistant-net.rules or the format of my ifcfg-ethX_* files, but haven't been able to resolve it.  Probably will leave it as "workaround works".
UUIDs and boot drives: Didn't solve this one either, but again didn't try very hard because the recove

Frustrated. Java on Centos 6 doesn't give an error message when downloading from a Samsung Galaxy S3

Rock — 2013-05-24T02:24:12

SUMMARY:
Maybe this all boils down to "how do we debug when Java fails on Centos 6?

DETAILS: 
If you don't have the Samsung Galaxy S3, then you might not realize how 
frustratingly difficult it is to transfer multiple files from the 
smartphone to Centos 6.

It should be as simple as hooking up a USB cable and dragging and 
dropping (which it is, on most other smartphones, including the Samsung 
Galaxy S2, which has USBMS mode still intact).
 
Note: I don't have a microUSB card, so that isn't an option and I have no 
desire to transfer the personal photos to the cloud just to get them from 
the phone to Centos, nor to install Wine and/or a virtuoal OS just to do 
something as simple as transfer files.

On the Samsung Galaxy S3, you can go all day to Settings->More Settings-> 
but there is nothing for "USB" anywhere anymore.

Unfortunately, [url=http://androidforums.com/computers/499522-looking-
linux-file-transfer-tool-android-4-0-devices.html]Google has apparently 
disabled USB transfer in the Android OS 4

Dell R320 server

Jerry Geis — 2013-05-23T21:04:24

Is there a way on Dell R320 (two power supplies and hardware RAID-1) on 
centos
to get a message that a power supply is failing or that one of the 
hardware RAID disks is failing?
Sure there is the front panel - but no-one is there ...

Is that reported to linux/centos some way?
This is my first R320.

Thanks,

Jerry

Changing disk UUID after cloning

Glenn Eychaner — 2013-05-22T19:58:54

So, I have a CentOS 6 system, and I want to make several clones of it.  I'm using Clonezilla to clone the drives; that's no problem.  But the drive UUIDs are driving me up the wall. After cloning, the two drives have the same UUID, but I'd like each clone to have different UUIDs so there's no possibility of a conflict when I am running diagnostics with two drives installed, etc. But when I change the UUID of the /boot or / partition (even if I update /etc/fstab), the system won't boot; it GRUBs OK (after I use recovery mode to rerun grub-install), but never gets to the 'Welcome to CentOS " message.  Do I need to "rebless" vmlinuz or initrd or initramfs in the /boot partition if I change the drive UUID?

Or should I just ignore UUID and go back to using labels in /etc/fstab (which is what I did in CentOS 5)?

Thanks,
-G.

SuperMicro with LSI MegaRaid with Centos 6.0

Gregory P. Ennis — 2013-05-21T17:54:17

Everyone,

I am trying to install a Centos 6.0 system on a SuperMicro with an LSI
MegaRaid SCSI 320-2 controller.  

I had originally tried to install 6.4, but the 6.4 install DVD does not
boot with this configuration.  
See :
http://bugs.centos.org/view.php?id=5377

Fortunately, the 6.0 install DVD worked fine until it failed to identify
the hard disc controller.  I checked the lsi.com site which had a driver
for RH 3 and RH4, but not 5 and not 6.  

The interesting thing about this machine is that I had Centos 5.0
installed without difficulty (that over time upgraded to 5.9)

Does anyone have any idea of a driver I could use to get Centos 6.0 up
and running.

Thanks!!!!

Greg Ennis

semi-OT: flashing the BIOS on an HP dl580 GT, afterward

2013-05-21T15:41:16

When last we saw our hero, er, sysadmin, he'd found that the "noarch" BIOS
update was, in fact, a self-extracting .exe file, and he'd extracted it.
Finally getting the ok to take the system down, the following hilarity
(for small values of hilarity) ensued.

First, booting off unetbootin to freedos was fine... except it was try to
guess which version - freedos + emm386 + himem, no himem, live CD only,
or, finally, "no drivers loaded", which works. It gags on something orders
of magnitude larger than it was written for, y'know.

Then I discover that the builtin type command does *not* have /p, and
there's no more command, and I should have read the longer files before I
started this. Fun with <ctrl-s> ensues.

Finally, I find what are actually DOS config.sys files, with different
extensions, and read them - they're one-liners, and find out how to run
the rompaq.exe that runs the utility to flash the drives, and run it. And
again. And again. And *finally* get the reason it's failing, and (to save

CentOS Dojo and Barbecue - Aldershot, UK on 12th July 2013

Karanbir Singh — 2013-05-21T15:42:04

Hi,

The next CentOS Dojo is coming to Aldershot, UK - a 45 min train ride
from London Waterloo station - on the 12th July 2013. We have a great,
and growing list of speakers already on the agenda, and another few
waiting to confirm.

And, the venue sponsors - catn.com - are going to organise a hog roast
barbecue and beet for everyone attending once the talks are done (
4pm'ish ). So another great reason to come along and say hi.

Details on the day: http://wiki.centos.org/Events/Dojo/Aldershot2013
Registration URL : http://centosdojoaldershot.eventbrite.co.uk/#

I will post another followup email once we have the agenda finalised,
but if you are in the area - or can get to the area on the 12th July - I
highly recommend you come along. Its going to be a great event!

Regards,

CentOS source rpm repository setup

Toralf Lund — 2013-05-21T13:53:00

Hi.

I thought I might set up my CentOS 6 system with a source rpm repository 
config, so that I'll be able to download srpm files via "yumdownloader 
--source" or similar. I'm thinking that in order to this, I have to add 
something like the following to the yum repos config:

    [base-source]
    name=CentOS-$releasever - Base (SRPMS)
    baseurl=http://mirror.centos.org/centos/$releasever/os/SRPMS
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

    #released updates
    [updates-source]
    name=CentOS-$releasever - Updates (SRPMS)
    baseurl=http://mirror.centos.org/centos/$releasever/updates/SRPMS
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6


The question is, what I specify as "baseurl"? The above does not 
actually work, as http://mirror.centos.org/ does not have SRPMS 
subdirectories, although I believe it did in the past for earlier 
versions. So, does anyone know of URLs I can use instead?

Thanks,


- Toralf

ReiserFS - status?

Rafał Radecki — 2013-05-21T12:11:31

Hi All.

What is the status of ReiserFS in CentOS at the moment? I have some servers
which use it as a loadable kernel module. I am thinking about a filesystem
for database systems and would like to know if ReiserFS will be maintained
in CentOS/Linux kernel in the future?

Best regards,
Rafal.

ICMPv6 Neighbour Solication request is not answered bylinux when IPv6 address is assigned via Netlink code.

Kevin Peterson — 2013-05-21T06:10:06

Hi, 

I have a process which is running as a linux service and assigns IP addresses using netlink to configued interface in linux.
For IPv4 addresses i do not see any issue with this assignment.

When i try to assign an IPv6 address, the address gets assigned successfully to the interface, but the Neighbour Solication request received for that address is not responded with and hence ping6 from a different machine doesn't work.

When i take the same netlink code and run it in a sample program the address gets assigned and the Neighbour solicitation is responded with a advertisement and hence ping6 works.

IP assigned by the program : 7000::15/32
IP on client machine from where ping6 is done : 7000::17/32.

Bot machines are connected to same Layer-2 switch.

I have flushed the ip6tables on both the machines just to rule out any firewall issues.

Thanks,
Kevin Peterson

NIC interrupts and packets per second ratio, how to calculate? There must be some way...

Alex Flex — 2013-05-21T05:07:40

Hello again guys,

Iam trying to asses the best hardware for a machine that procceses a 
high number of packets per second on its NIC. THe only way I can achieve 
this without guesses is If iam able to understand or test what the 
number of interrupts available per core and how to translate that to PPS 
capabilities.

So far ive been testing an Core I5 CPU  and was able to achieve up to 
400k packets (small syn packets) in a single core (2.8Ghz i think..) 
untill the point where 100% was reported to serve as hardware 
interrupts, yet what is the math behind this?

In any case, i find this rather low and confused as I know for a fact 
that small home routers even on gigabit have specs that detail they can 
do packet forwarding at rates up to 1.4 million pps and iam sure there 
CPU is no where as powerfull as a 2.8Ghz Core I5 core.

Any orientation is much appreciated.

How to load balance interrupts of a NIC on the PCI-MSI-edge driver in CentOS? :(

Alex Flex — 2013-05-21T04:53:22

Hello CentOS !

Iam trying to configure a Dual Core 1.6Ghz AMD E-350 machine to be able 
NIC (eth0) interrupts the most efficient way possible so that I can be 
able to handle the large number of random source packets per second. 
Currently running CentOS 6.4 2.6.32-358.6.2.el6.x86_64, i made some load 
testing with a random sourced syn flood to the NIC of this machine and 
found out according to top all the CPU interrupts are being sent to 
CPU0, thus saturating it and keeping the second core 100% idle because 
of this the amount of PPS handled is low (50k /sec). So.. below the 
output of /proc/interrupts, and also the output of the SMP affinity file 
which already contains "3" which I expect it tells the kernel to load 
balance the interrupts between the two cores and its not happening.

Questions:
a.) Could anyody please help me with a solution so that iam able to 
balance equally the interrupts on both cores?
b.) Is there anyway to actually assign more interrupts to this IRQ (25) 
or is that something th

Where did yum install monodevelop?

Now.  When I went to my terminal and ran monodevelop... nothing.  When
I tried to locate the actual executable by running
find . -name "*monodevelop*" (kinda overkill, but figured that I'd get this
option out of the way), I couldn't find anything.  So, now, I'm scratching
my head and wondering what to do next :) .  Where did I mess up?  Am
I not starting monodevelop correctly?  If so, how should I start it?
