It's not without it's problems though, especially when using yum... Blindly
playing with this repository can be bad for your system's health, plenty of
care and attention is required...

The packages require quite a bit of ongoing maintence once installed and not
all versions are stable... The packages don't tend to carry much
documentation, the reported requirements are not always accurate and the
package clean up routines are never complete...

yum update girlfriend doesn't typically work too well if a prior version is
already installed, newer versions get installed then a cleanup happens
afterwards, race conditions exist where the previous version can do lots of
bad things to your system while both versions are effectively installed at
the same time... a yum remove girlfriend before a fresh yum install
girlfriend is recommended... Care should still be taken as yum will attempt
to honour the package dependancies and other packages such as pet, house and
car could be removed when trying to remove girlfriend, especially if any of
those were installed after girlfriend and more so if it was requires of the
girlfriend package that triggered their installation... Typically there are
significant system reconfigurations required to support each new version...
yum reinstall doesn't always work too well with girlfriend, the package does
tend to leave quite a bit of state information in place, even after
uninstall, which, if this is the cause of the problems, won't be fixed by a
reinstall...

An upgrade of girlfriend to wife exists, it's not cheap though and
potentially can require some major system reconfiguration to support... yum
can't really handle this, often getting confused between the option of
upgrading to wife or updating to a later release of girlfriend... The
upgrade to wife can be forced in certain situations such as if any child
packages have been accidentally installed, such as by automatic overnight
updates...

With wife installed, yum will let you install additional versions of
girlfriend, but, this is not a recommended configuration as there are some
very serious interoperability issues, especially if an installation of
girlfriend pulls in a child update... In that situation, yum would try to
upgrade girlfriend to wife, but, as you can't, in a standard configuration,
have multiple instances of wife and newer versions of wife obsolete older
versions, the old version would need to be removed, the massive number of
unresolvable dependancies involved in the that would cause yum to crash...
The only solution is to use rpm with varying force and nodeps options to
attempt to get your system functional again, though even then, bits of old
packages will still be lying around consuming resources, especially if child
packages exist...

So, while the packages can work, there is quite a bit of work involved in
fully integrating them and maintaining them... yum can be used, but, it's
probably best to exclude them in yum.conf and manually install and update
the packages where you find necessary, taking great care in avoiding
conflicts and managing dependancies... The extra care taken in doing it
manually can really pay off in long term system stability...

I've tried a few different versions of the proprietary driver with no

try some more versions. Maybe I'm lucky. ;-)

[CentOS] Updates for csgfs on CentOS4

[carlopmart]

Hi all,

  I am trying to install csgfs on two CentOS hosts. I have installed latest 
kernel from updates repository. But when I try to install csgfs, yum returns me 
this:

Dependencies Resolved

=
  Package Arch   Version  RepositorySize

Is this ok [y/N]

  Yum tries to install kernel 2.6.9-78.0.1.EL. Where are the updates modules 
for 
csgfs to use with kernel 2.6.9-78.0.13.EL??

Thanks.

what facility? Everything Benjamin explained is there.

I'm not getting any email to r...@ on my servers. I suggest you try to 
find out where you might have exposed it. Spammers try to avoid sending to 
root.
Or, are you sure the mail is *really* sent to root and not to an address 
aliased to root? Lots of users (basically all users that were created for 
use by a daemon) on the machine are aliased to root.

If it's really spam straight to "r...@domain" a simple "r...@domain 
nouser" in virtusertable or access.db should usually solve the problem as 
cron rather sends to "root" or "r...@localhost".

[CentOS] Dual-boot with WinXP, CentOS already installed

[Sorin Srbu]

Hi all,

I'd like to deploy a solution with dual-booting systems where CentOS 5.3 is 
already installed and WinXP will be installed to a separate disk.

I found 
http://apcmag.com/how_to_dual_boot_linux_and_windows_xp_linux_installed_first.htm?page=1
 
and it seems straight forward enough, although the description is for Ubuntu.

The problem as I see it, is that the how-to differs from how CentOS looks in 
/etc/grub.conf and the boot-loader in Ubuntu with respect to making grub work 
again after the Windows install.

I found Tldp.org mentioning dual-boot plenty, but most or all articles listed 
are using lilo as a boot-loader, which seems a bit obsolete and besides I 
can't quite translate the instructions from lilo to grub. 8-/

Basically, what would I need to change in the how-to from apcmag.com above?? 
Thanks for any pointers.

Googled some more. Realised /boot/grub/menu.lst *is* /etc/grub.conf... Duh!

Also some people say it's better to have Windows installed to the first
harddrive and the first partition (so that C: is the where it should be on
1st hd/1st partition). 

Would I be better off disconnecting the drive containing CentOS and
reconnect it when I'm done installing Windows. Then boot with CentOS rescue
and reinstall grub to the Windows-hd MBR?

[CentOS] Weird performance problem

[Ugo Bellavance]

Hi,

I'm running a CentOS 4.  server and I sometimes face a weird problem. 
It is a weird performance problem, and here is how I discovered it.

This server runs OpenVZ virtual machines, and one of them is an asterisk 
server for my personal use.  The first symptom of the problem is that 
the voice quality became flaky.  So I logged on the server to see what 
could be eating cpu cycles, when I ran top, it took almost one minute 
before top actually showed.  Another hint is that when I run dstat (a 
monitoring utility that is a mix of iostat and vmstat and other stats), 
I often get a "missed xx ticks", where xx is a number.

Example (current) (sorry for the wrap):

total-cpu-usage -dsk/total- -net/total- ---paging-- ---system--

  missed 30 ticks



The problem is currently occuring, but it doesn't seem to be affecting 
voice quality for now, so I have some time to try to find the cause. 
The only solution I've found up to now is to reboot... But hey, this 
isn't a Windows 98 machine :)!

I tried restarting the VZ system, which restarts all the VMs, but it 
didn't solve the problem.  I can't tell if the problem occurs on a stock 
centos kernel, because the server is running production (but 
non-critical) virtual machines, so it is always running the openVZ kernel.

So here is what I've done for now:

- Top shows a load of about 0.4

- vmstat 1 10 shows this:

Look for the release notes, and, at worse, look the upstream release notes.

Another hint is that pings are really slow.  Even pinging localhost is 
very long.  The first reply is fast, but the second takes ages to come.

It seems to be blocking here:

recvmsg(3, 0xbfbf84b0, MSG_DONTWAIT)= -1 EAGAIN (Resource 
temporarily unavailable)
gettimeofday({1239887784, 389347}, NULL) = 0

The rest comes as soon as there is another response:

gettimeofday({1239887903, 119727}, NULL) = 0
gettimeofday({1239887903, 119791}, NULL) = 0

Then it blocks again...

This confuses Nagios that is running in a VM on this server.

Can the 'gettimeofday' be the problem?  'date' runs w/o delay.

It's like that tutorial says. Forget about backing up grub.conf. This is 
nonsense. You want to make a backup before changing it, just in case, but not 
because of the XP installation.
After the installation you have to reinstall grub with "grub-install" (from a 
live disk) and add the chainloader stuff to grub.conf.

mount /dev/sda2 /mnt/linux (if that is where you linux resides)
grub-install --root-directory=/mnt/linux /dev/sda
(if you want to install it to the partition use sda2 instead of sda, then the 
partition has to be active, so that you can boot from it)

Instead of using grub-install you can backup the mbr before the installation 
and then restore it afterwards. You can easily get bad results from that if 
you mistype, though.

[CentOS] SELinux errors on my CentOS 5.3 (32 bit) Desktop after upgrade from 5.2

[Lanny Marcus]

I am running SELinux in Permissive mode. GNOME and KDE are installed.
Following the upgrade from CentOS 5.2 to 5.3 (32 bit) I am getting
SELinux messages. Possibly of interest to someone here or upstream?
(Since I'm using Permissive mode, this is not a problem for me). If
these are known issues, please disregard.  Messages follow:

(1) SELinux is preventing nm-system-setti (system_dbusd_t) "getsched"
to  (system_dbusd_t).

SELinux denied access requested by nm-system-setti. It is not expected
that this access is required by nm-system-setti and this access may
signal an intrusion attempt. It is also possible that the specific

I've had nothing but good results with dual-boot *if* Windows is installed
first and then add linux. The other way around is a first for me.

Generally speaking, which one is the easiest and/or safest if time is an issue 
and you want to things fast and streamlined doing this, grub-install or backup 
and restore MBR. That is assuming I don't screw up when I do either and 
mistype or something.

Or are both things different sides of the same coin kinda' thing?

Why? If you want to put them on separate *hardware* then you don't have to 
reinstall anything. Just make sure that the CentOS drive is the first boot 
drive.

The kABI-tracking kmod-xfs for CentOS-5 started in Oct 2008.  The
CentOS-4 version has been tested and will be offered shortly (as soon
as you/Tru builds it for release).  :-D

But the code is somewhat getting old.  Maybe it's time to get the
project xfs going again?  Tru is the leader of this project.

I think I prefer the grub-install way because it's easier to remember what you 
have to do and harder to mistype. Using dd works 100%, though, if done 
correctly. 
Even if there is something wrong with grub-install or grub in the live disk, dd 
is hardly affected. But, as I said, if you use two disks and pull the first out 
you do not have to reinstall/restore the MBR anyway.

Re: [CentOS] Acrobat Reader 9 on Centos 4.7

[Bart Schaefer]

On CentOS 4 I'm getting

/opt/Adobe/Reader9/Reader/intellinux/bin/acroread:
/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.5' not found (required
by /opt/Adobe/Reader9/Reader/intellinux/bin/acroread)

The latest acroread I can find that's NOT the one in the Adobe
repository (which is where that one came from --
AdobeReader_enu-9.1.0-1) is version 5 from rpmforge.  Can anyone point
me to a more recent working RPM for CentOS 4, as in, approximately
version 8 ?

Of course you change files. But it works as well, yes, just checked it out. I 
wasn't aware of this, although I have EasyBCD already installed on my Windows 
7 netbook. However, if you do it this way you have to rely on the BCD boot 
loader and the Vista partition.
I would recommend it if you use the Linux OS only irregularly. If it is your 
main system using only the Linux-native boot loader surely is recommended.

I'm not sure, but I think you will also need to have grub installed to the 
Linux partition. So, if you installed it on the MBR it may fail to boot.

I also got these type of messages.  I just did a yum update from

As noted in other replies, Windows not not play well with anything 
else.  Your best bet would be to disable/remove/disconnect the drive 
with CentOS and then do the Windows install to the other drive.  Once 
Windows is installed, you can reconnect the CentOS drive and then easily 
edit grub.conf to boot Windows using the "chainloader" directive.  This 
approach will only work if there are no primary partitions on the CentOS 
drive that Windows recognizes.  Windows (just like DOS) assigns drive 
letters to partitions in drive number order starting with the primary 
partitions and then moving on to the extended partitions.  The bottom 
line is that you want the first Windows partition on the non-CentOS 
drive to get assigned drive letter C: when Windows boots.  As long as 
Windows doesn't recognize the partition type (e.g., ext3), no drive 
letter gets assigned.

The problem with suggestions to just install Windows and then either use 
another boot loader or repair the grub installation is that you are 
stuck doing that work through Windows.  My experience has been that 
Windows isn't as easy to work with for making changes to the boot loader 
and any approach that overwrites the Windows boot loader may leave you 
with Windows not being bootable.  The approach I described above leaves 
the Windows boot loader in place although you may need to edit 
C:\boot.ini to make sure it can still find Windows when both disks are 
"present."

Here is the grub.conf that I use on my laptop.  The internal drive boots 
to either CentOS or Windows while Fedora 10 and Ubuntu are on an 
external USB drive.

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#  all kernel and initrd paths are relative to /boot/, eg.

My grub.conf points to Windows on a partition on the internal drive.  
Yours would point to Windows on the "second" drive (probably hd1).  
Likewise, your boot.ini will need to point to Windows with something like:

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP"

changing to:

multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP"

Note the change -^

I'm assuming your Windows disk would end up being /dev/hdb in a Linux 
world.  If your system is using SATA drives or the Windows drive would 
be something other than /dev/hdb, you may need to make some adjustments 
to what I have suggested.

Cheers,
Dave

You can always boot the centos install CD/DVD with "linux rescue" at the 
boot prompt - or use a knoppix or other live cd distribution.  And it is 
a good idea to be prepared for this.  I don't know if you want this, but 
it is also possible to set up VMware server with access to the raw 
device so besides dual booting you have the option of running the other 
OS as a VM guest.   Most windows versions have to be re-licensed when 
they see different hardware even if it is virtual so you may have to use 
windows as the host for this if you do it often.

Toby: M$ is completely unaware that any other OS exists. Or, they will
never admit to that.  However, 1 or 2 days ago, I saw a listing for a
temporary job assignment in Redmond, WA, with "The Software Giant",
for someone to work with a team of people who are the only ones there
who work with Linux. They are the "Linux experts" in that place.  I
assume it is for M$, but not positive about that.   :-)  There is a
web page on the CentOS Wiki about how to reinstall GRUB, if it gets
trashed or is overridden when installing another OS.Lanny

GAG is a standalone boot disquette / boot CD.  It doesn't need Winblows 
or anything eles.  It just installs itself on MBR and the boot media 
contain the config utility with the "write to MBR" function.

You just have to instruct Linux to put all its stuff to its partition. 
I'm not very familiar with all the Linux boot stuff, so i can't comment 
on how to do it for somebody that had Linux installed first.  I'm sure 
somebody on the list can give us infos about it and using GAG on MBR 
afterward.

Winblows tries to do its best not to ask anything to the user and decide 
by itself.  No wonder why tons of worms are spreading under Winblows! 
One have to say that a large part of this is due to bad design but 
trying to do everything in place of average Joe is wrong.

I've never seen this problem at all - running AMD 64x2 7750, 4Gb
memory with GEForce 7200gs card, nvidia driver
nvidia-x11-drv-173.08-1.beta.el5.rf.x86_64 (from rpmforge - duh).
I've used a 19" CRT, 17" 1280x1024 flat panel and, currently, 22"
1680x1050 flat panel (Emprex - cheap, but works great).

I tried the L&G nvidia driver last year some time, but I decided I'd
rather have the rpmforge working dkms driver than the L&G, even though
it's a beta driver.  When I upgraded to 5.3, that was the first time
the driver was actually rebuilt for the kernel since 5.0.

I think it's worth while to keep xfs updated for a while until ext4

[CentOS] CentOS 4 dkms-ndiswrapper

[Agile Aspect]

Hi - I'm trying to get wireless running on CentOS 4.7 on a dual core laptop
(latitude-e4500) for an employee.

I'm having trouble with building dkms-ndiswraper-1.54-1.el4.rf -
enclosed are the
errors messages.

The kernel was rebuilt to disable CONFIG_4KSTACKS.

The errors prior to rebuilding the kernel are identical to the errors after
rebuilding the kernel and rebooting - minus the error regarding the
CONFIG_4KSTACKS.

Basically I just typed

  make

in the directory.

I'm using dkms this time - I've never used it before. I'm under the impression
that all I had to do was type 'make' in the directory in the ndiswrapper
directory.

Any help would be greatly appreciated!

[CentOS] OT: Possible for Malware against Windows boxes to attack Firefox on Linux?

[Lanny Marcus]

My belief is that this is not possible, but there are many extremely
knowledgeable people participating on this list and I would like to
know if it is in fact possible. I am running CentOS 5.3 (32 bit) fully
updated. Browser is Mozilla Firefox v.3.0.7.

I believe both times this happened, once yesterday and once today, I
was surfing on the web site of my favorite singer/musical group; or in
the forum, which is a highly restricted area. Today when it happened,
I believe I was looking at a video coming from YouTube.com

I contacted the webmaster, someone I communicate with frequently,
thinking that something on one or more of his web pages is infected,
but he wrote back, thinking that my box (dual boot MS Windows XP and
CentOS on the same hard drive) is infected by this malware and that
his web site is clean. Below is part of the description he sent me in
an email. I have seen the pop ups, a request to install
Install-2006-60.exe which I declined, etc. Comes from
  Is there any way the Firefox web
browser could have been corrupted by this, while using CentOS Linux?
 TIA!  Lanny

Malware Description:
Antispywarepcscanner.com appears to be another web pimp of the
hazardous fake anti-spyware tool called Personal Antivirus. Do not get
flattered by the seemingly decent-looking and pleasant design of

Besides, Antispywarepcscanner.com may act as an obsessive
browser-hijacker that redirects your web-surfing to its URL without

redirections are preceded by the intrusion of Zlob trojans that
obscurely trespass on your PC and forcedly modify browser settings.
When you hit Antispywarepcscanner.com, you will see either the
misleading advertising of Personal Antivirus scareware, or witness the
deceptive online scan performed by the above-mentioned rogue utility.
No matter what tricks the fraudsters prepared for you on

Red Hat Enterprise Linux ES release 4 (Nahant Update 4)

openssh-server-3.9p1-8.RHEL4.15
2.6.9-42.ELsmp

uptime 944 days

Started getting the eavesdropping message from a login that is
supposed to login w/o a password.
And always did before today.

That would make me very suspicious that the box had been cracked,
and that a foreign sshd had been substituted for the real one.

rpm -V is your friend.

After trying for 2 hours, I ran into 3 brickwall-issues. Like you found, there 
are two base perl modules which require newer versions than that which comes 
with 5.3. These modules are
File::Temp  and Encode   (core)

cpan2rpm can package them OK, but there are fatal transaction check errors when 
installing.

Mr. JV is the author of RT3 and DBIx::SearchBuilder. The SearchBuilder module 
also stopped me (briefly) with a dependency on DBD::Oracle. To grab this from 
CPAN requires the supporting Orable Libs. I altered the spec and removed any 
Oracle depends.

These 3 issues were enough to cause me to give up.

Re: [CentOS] kernel update doesn't update grub.conf

[Devin Reade]

[I saw this thread in the mailing list archives, but wasn't subscribed
at the time, so sorry it's not a proper follow-up.]

The symptoms you describe could be a side effect of being previously hit by
 and
.

Those bug items describe workarounds.  After you get mkinitrd upgraded
to that in 5.3 the problem should go away, although you may have to 
manually fix up the results of the bad kernel install.

My experience is that when browsing on any OS and you come across an 
error message stating that your computer is infected and you need to 
install such and such software, the web site I was visiting has an XSS 
exploit that was taken advantage of to try and get you to manually 
install a piece of malware.

Install the FireFox extension "noscript" and be very careful about what 
domains you authorize scripting from.

The fact that an XSS attack was able to give you a phony message means 
the same site could have XSS that reads your cookie and steals your 
session ID.

Noscript reduces the odds of such attacks being succesful.
