if you run a yum update, you will see that all 6.0 updates ( except, yes
firefox and xulrunner ) are all in place. The 6.1/ stuff should be
coming through soon. There are a couple of rpms that are not doing the
right thing and we should have those resolved in a day or so.

Re: [CentOS] Subnet expansion

 Hi all,
 Can pls share your experience on this?

 Currently I have this network:
 10.1.16.0/22.
 10.1.16.0-10.16.17.254 are DHCP managed
 10.1.18.0-10.1.19.254 are statically assigned

 If I need to expand it to:
 10.1.16.0/20

 1. What is the best way to do it with minimal network disruption?

 2. If I keep some machine with 22 subnet mask, will it still be able
 to talk to the other machines in it's range?

Seeing as noone else has posted anything, you can have my thoughts.

I think the answer to this part is not trivially.  A machine in the /20 subnet
will expect to be able to talk directly to a machine within the /22, but that
machine will want to talk via a router.  You can hide subnets within subnets
using arp-proxying, but I'm not sure there's an easier way.

A machine within the /22 would be able to talk to any other machine within
that /22 (even if they're configured to use /20), but won't be able to happily
talk to machines within the /20 but outside of the /22.

Re: [CentOS] ext4, 4k sector alignment

thats by cylinder, which is an old MSDOS legacy thing. I believe
parted and probably some other programs let you partition by sector instead.
In my kickstart pre script, I use:
... | sfdisk -H $HEADS -S $SECTORS -uS --force -L $DEVICE
For SSDs, I saw the recommended respective values: 224 56 (or 32 32)
fdisk also has -u for sectors unit, and -H/-S to force a fake geometry.

But I must admit that I am still a bit confused with all these alignments...

The key thing is to be sector aligned per physical drive; align to eight sector
blocks; a starting sector of 56 would work. With RAID and LVM alignment to
chunks or stripes is desireable.

Forget CHS specifications; they haven't been valid for years anyway; think LBA
and only LBA and you'll be fine. No drive made actually has 255 heads
anyway or a constant 63 sectors per track, either, for that matter. All
mechanical hard drives made these days employ ZBR and have a variable number of
sectors per track, less than ten (or 12, in the case of some 15K RPM FC and
SCSI drives that I know about; have some 15KRPM 36GB SCSI drives with six
physical platters, 12 genuine physical heads, all in a half-height 3.5 inch
form-factor) heads, and many thousands of cylinders.

SSDs don't even have heads or tracks, and thus those specifications are
meaningless and need to just go away. It's LBA all the way, and the critical
alignment is to erase-block size.

See the following articles for more, and better, information that goes into a
lot more detail than I have time to do:

Re: [CentOS] Upgrading from CentOS 5.6 to 6.0

2011-07-26 Thread Jim Wildman

Several points (all for enterprises I've worked at)
1) Folks tend to hold onto hardware WAY past the expiration date.  We
still have SunFire v1xx boxes alive and some x86 boxes that aren't 64
bit capable.  If they want the latest OS, buy new hardware.
2) I've never seen an OS upgraded across major releases under an
existing app (other than a web server).  Generally it is the other way. 
The app guys want to run the new version, which requires the new OS, which 
requires new hardware, which requires a full recert.
3) Just because IBM can do it on mainframes and Power/AIX boxes, doesn't
mean you can do it on x86 hardware.  Or should even try. 
4) As others have noted, comparing RHEL to Fedora is not valid.

 This is roughly what Microsoft used to aim for (somewhere on the road 
 between XP and 8 they seem to have totally quit the idea, though).

As a slightly off-topic aside, there is a youtube video out there about doing 
just that; the video shows an upgrade chain that goes from Windows 1.0 (no, 
that's not a typo) up through Windows 7, all as upgrades, along with all the 
things that have to be changed along the way some of the text the guy 
enters in textboxes is NSFW, however.  So you'll have to google for it 
yourselves; it made Slashdot a few weeks back, so it shouldn't be hard to find.

I'm sure that some of these major upgrades *can* be done, but in a land where 
the package is the unit of OS granularity, and package maintenance practices 
vary from package to package as to 'upgradeableness,' it really becomes a task, 
and this is before even considering the upgrade-hostile attitudes of some 
software projects that upstream ships packaged in upstream EL.  

While package groups give an illusion of a unit larger than a package, it's 
just an illusion, really.  The collective set of dependencies defines the full 
distribution, and nothing in the dependency chain requires rigorous, tested, 
upgrade path implementation.

In the case of other commercial vendors doing this, well, those vendors 
typically have strict and tight control over all the developers working on it, 
and have enforcement mechanisms in place to ensure that migration paths are 
implemented.  It's called an employment contract, and it's enforced through the 
ordinary commercial developer chain of command.  

While open source developers and packagers are technically capable of doing 
this, some seem to take great delight in making it difficult to be compatible 
(partly to prevent closed-source programs from continuing to work).  And if 
just one development group becomes the proverbial fly in the ointment, then all 
the users of that package that need upgrades to 'just work' suffer.  And 
sometimes the developers care, and sometimes they don't.

But consider: upstream doesn't employ a 'critical mass' of developers in all of 
its shipped packages to reliably enforce upgrade provisions, even if it wanted 
to do so.

Beyond that, there are packages supported by upstream that have serious 
difficulties with major version upgrades, simply because supporting data in 
place upgrades is not a priority for that development group.  I can think of 
more than one project that seems 'upgrade hostile' but in reality it's just 
something that's not front burner; they'd rather develop newer features and fix 
bugs than 'waste' time on a rarely used procedure that is, in some cases, 
extremely complex and in other cases simply won't work anyway.  That is, there 
are data sets associated with some upstream packages that are impossible to 
migrate in place to a newer version in a seamless, nondisruptive, fashion.

In a nutshell, it becomes a tradeoff of open source freedom versus the upgrade 
needs of the users.  If the needs of the users trump the freedom of the 
developers, then developer freedom (the freedom to 'scratch ones own itch'), 
the very essence of open source, goes out the window.

To the OP, if your itch is to have seamless in-place upgrades, then scratch 
that itch (or pay someone what scratching that itch is really worth... but be 
prepared to come up with six or seven figures).  That's going to be a mighty 
big itch, though. especially with over 2,500 upstream packages from nearly 
as many heterogeneous development groups with many more agendas of their own.

Keep in mind that the Linux kernel itself makes no concessions to 
backwards compatibility and demands that all related modules be 
recompiled to match changes.   Enterprise distributions have their hands 
full just trying to keep things working within the life of a major rev 
and are generally restricted in how much new development can be added 
without major breakage.

Other OS kernels have more reason to maintain backwards binary 
compatibly (i.e. paying customers that demand it...).

[CentOS] Problem with /etc/security/console.perms.d/51-local.perms

2011-07-26 Thread Thomas Johansson

I'm having trouble to get rules in /etc/security/console.perms.d to work 
properly. I have found no clue reading forums. The same problem appear 
also in Scientific Linux6 and Fedora13/14. The rule i add works fine on 
centos 5.

total 4
-rw-r--r-- 1 root root 283 Jul 26 15:48 51-local.perms
hostname:/etc/security/console.perms.d# head -2 51-local.perms
usbserial=/dev/ttyUSB[0-9]*
console  0660 usbserial 0660 root.uucp

When i read docs for RHEL 6.1 i found this
Removed references to 50-default.perms, since this file was removed in 
Red Hat Enterprise Linux 6, per Bugzilla 630524.

I have no access on redhat and cannot read the bugzilla report. COuld be 
related to my issue.

ANyone who knows what the problem is or have any workarounds for this?

Yes, its only a slight over-generalization to say that free projects

Even though RHEL isn't a free project, there's only so much they can do

[CentOS] Question about CentOS 6 installation setup

2011-07-26 Thread Mark

When I created a CentOS VM (using VMWare WorkStation), I installed
with the first DVD, and the disk partitioning and installation was all
done automatically with almost no input required from me.

The problem with this is that the /boot partition was too small (under
50MB) and I couldn't update the kernel (it blew out with a grubby
error, which I did not recognize - separate thread on that).

Is this a manifestation of using VMWare for the VM platform, or is
this normal for a 6.0 installation or what?

have copied the original and used that copy to create a test 
environment. I have run through all system updates and have upgraded all 
relevant packages. The test system is at 5.6 now.


Currently with Windows machines I can't just connect to the SSID and 
enter in a username and password. I have to go and manually add the 
SSID, modify some settings; specifically turning off validating server 
certificate, turning off automatically use my Windows login, and turning 
on User or computer authentication mode.


We also have some OS X clients. Fortunately connecting via OS X is 
easier. The catch is that I have to join the machine to our domain. 
After that it's pretty much username and password, and they are on.


Ideally I would like to have a simple connect to this SSID, enter your 
username and password and that's it solution and still have all 
requests checked against our Active Directory server.


On a side note. I'm going through my settings trying to get this working 
more smoothly and I ran across:


wbinfo --a user%password (yes I'm adding in my username and pass)

plaintext password authentication succeeded
challenge/response password authentication failed
error code was NT_STATUS_ACCESS_DENIED (0xc022)
error messsage was: winbind client not authorized to use 
winbindd_pam_auth_crap. Ensure permissions on 
/var/cache/samba/winbindd_privileged are set correctly.

Could not authenticate user MYUSERNAME with challenge/response

I know the 2 error lines are permissions related. I'm not sure what the 
permissions should be on this file/folder. Can someone let me know this?


The tutorial from FreeRadius says that I should get output similar to:

plaintext password authentication failed
error code was NT_STATUS_NO_SUCH_USER (0xc064)
error message was: No such user
Could not authenticate user CHSchwartz%mypassword with plaintext password

Yet

ntlm_auth --request-nt-key --domain=MYDOMAIN --username=MYUSERNAME
NT_STATUS_OK: Success (0x0)

So the Auth is working. I don't understand though why my AD server is 
letting cleartext passwords through. It shouldn't right?


Any help would be greatly appreciated.

While the problem is bad metadata, should yum really be left off the 
hook for segfaulting when it gets bad data?  Shouldn't yum catch that 
error with checks, then exit gracefully with an error code?

(If there are already sanity checks, adding one more to catch a null 
pointer being passed would be a natural extension of those checks.)

sure, but you need to take this upstream to get attention. I just dont 
see this as an important enough issue to fix within centos here. 
Expecting valid metadata should be a reasonable assumption.

Maybe we should start signing the metadata as well just as an added step.

No. Programmes that crash on bad input are vectors for exploits. Even if
it's unlikely someone would put an untrustworthy repo in his config yum
shouldn't segfault on bad data.

I agree. It should report that the checksum is bad, and skip to the next 
repo.

 (thought: could bad metadata cause an exploitable segfault?)

I hope not! In either case, it is Redhat's issue, not ours, and
the bug should be filed with them.

ah you see, we have a bit of room when it comes to yum and package

*should* consider local fix's. With due testing and perhaps limited

[CentOS] Gimp PDF plugin - Centos 5

2011-07-26 Thread Frank Cox

Gimp on Centos 5 has somehow lost its ability to load a pdf file on three (i386)
different computers.  I'm pretty sure that this used to work.

When I try to load a PDF file I get the initial box titled Load Postscript
with rendering and antialiasing options, but when I hit OK I get an error
message:  Opening filename failed:  Plug-In could not open image.

Comparing between Centos 5 and Centos 6 I see that I have a file named file-pdf
in the gimp plugins directory on Centos 6 x86_64 (/usr/lib64/gimp/2.0/plug-ins)
but that file is not preset on the Centos 5 boxes..

just a stab in the dark here -- upstream issued an update to 
poppler / evince that obsoleted xpdf (gratuitiously) mid 
ABI lifecycle in 5, seemingly for a security matter that 
seemed, to me to be a mild local exposure, only

$ ldd /usr/bin/gimp | grep pop

perhaps a needed helper application is now absent?

This programm  works fine.

Gimp can load a pdf file on Centos 6.

Something has got blown up only in Centos 5's gimp that didn't affect gimp in

Gimp can still render postscript on Centos 5, it just doesn't know how to

One random thought: On *some* VM setups (and I believe the OP is using
a VM), some of the boot infrastructure might be missing or exists only
the host system, so it might not be possible to upgrade a VM's kernel
while inside of the VM.  (I know that is the way it is for the CentOS 4
VPS I rent from Tektonic).
