It /did/ require Oracle, but it doesn't any more.  To be honest, getting it
working with Oracle was a piece of cake, and the 1G limit wasn't really an
issue as the active database isn't that big.  The 4Gbyte limit on database
size on disk with the XE edition /was/ an issue once you were managing a large
numer of machines.  The defaults that it ship with work fine, other than a
couple of values that can improve performance that are documented on the
spacewalk web site.

I've used spacewalk since 0.1, and it's really not that bad at all.  There's
bits of it I think could be better, but it's not the 'horror' you seem to
think it is.

This is true, certainly 1.4 is almost completely working on PostgreSQL.
Monitoring is the only thing listed not to work with PostgreSQL on 1.5 (which
isn't quite out yet), but that's not the end of the world.

I'd switch to HTTP on the basis that HTTP seems to be the more 'normal' way to

OK Mogens.

That seems to be a reliable option to use across a network. 
What's all the fuss about NFS, when it's trivial to create a 
temporary directory in the Apache DocumentRoot and put the 
ks file there?

Yes. At least there are no version changes with the http 
protocol that would bust anything, and it still works over 
the network. Myself, I use my kickstart file from a USB 
flash drive, so that works on a machine without a Floppy DD 
:)

I know you used python in the end, but for the record this should have been:

IFS=$'\n'

i.e. the \n has to be expanded to a newline, otherwise it causes word 
splitting on either '\' or 'n'.

Actually there are cases where you do want swap ~= physical (even though you 
wont be "using it". For example, if you need to increase the ulimit for stack 
size (some apps need this) then for a normal fork the kernel will need (free 
phys + free swap) > this.

So in the end you'll need a bit more swap then your required stack size limit.

Worth noting is that if you set it to unlimited then you don't need to reserve 
any swap for it...

Thanks very much.
Actually protocol ICMP does not seem to be allowed 
in the Firewall on my Billion 5200S RC.
But I see that this protocol is allowed in "Access Management".
I just tried adding a rule with ICMP protocol,
but it seemed to have a bad effect!
(I was cut off from the outside world.)
I'm sure this is the right way to go, anyway,
so I'll continue my experiments.

[CentOS] Bug in 6.0 i386 Basic server install...

2011-07-21 Thread John Doe

Hey,

I tested centOS in vmware player (512MB, 1 IDE disk) and bumped into a post 
install failure to boot.
While the minimal install works all the way, the Basic server one fails at the 
first post-install boot with following:

  modprobe: FATAL: Could not load /lib/modules/2.6.32-71.el6.i686/modules.dep: 
No such file or directory
  ...
  No root device found
  ...
  Boot has failed, sleeping forever

I used the same partioning scheme as the minimal that is working fine...
/boot ext4 sda1
swap on sda2
/ on sda3

Tried with a SCSI disk image, and Basic server works fine...


Known issue with IDE?

Thx,

JD

[CentOS] How to remove Microsoft soft raid?

2011-07-21 Thread David McGuffey

Have a quad core workstation that was running WinXP_64 that I want to
blow away and install CentOS 6.  C6 install process finds raid metadata
associated with sda and sdb, and then excludes them from the rest of the
installation process.  

There doesn't appear to be an option for disassembling the raid as part
of the install process.  I think there should be.

Any tricks to removing/by-passing the soft raid left over from the
previous OS?

Can you see the 2 HDD's in the console, when you run fdisk -l?

If so, then simply use fdisk to remove all the partitions, then use
the installer to partition and format them

I usually boot from the installer CD and go to a virtual terminal (Alt-F1).
In the shell;

I'd guess that the partition table has some microsoft funkiness in it that
needs to be wiped.

Take, care with this, it can and does eat data...

This problem has been resolved.  A silly editing error replacing 5->6 also
changed the IP-address :-(  With the correct IP-address Kickstart works
correctly with an NFSv3 server as shown above.  No need to upgrade to NFSv4
and Kerberos :-)

For the record, it is in fact possible to add NFS mount options to the PXE 
APPEND line, as documented in 
http://fedoraproject.org/wiki/Anaconda_Boot_Options.
To explicitly force an NFSv3 mount you may add the following NFS mount option:
ks=nfs:nfsvers=3:servername:filename

Thanks again for everybody's help.

If this does not work, try to erase the LAST cylinder of each disk.

 The company has ramped up kernel contributions in hopes of adding
 Hyper-V drivers, which it has worked on for more than two years


Microsoft  isn't exactly 
dumping Windows  for Linux 
, but it has become one of 
the busiest contributors 

 
to the Linux kernel. Microsoft's attempt to get Hyper-V drivers into the 
Linux kernel has taken longer than expected, having begun in July 2009

so Microsoft is apparently trying to speed up the process.

Microsoft was the fifth-largest corporate contributor to Linux kernel

*LINUX FOUNDER* Linus Torvalds has said that he's delaying the release of

Torvalds announced back in May that the Linux 2.6.40 kernel will be

[CentOS] nouveau driver one centos 6

2011-07-21 Thread Jerry Geis

I "wish" to not load the or even install the nouveau driver by default.
I want to use the NVIDIA binary driver.

I have tried a number of things:

1) in my kickstart package section add the line:
-xorg-x11-drv-nouveau

This did not work - it was still installed.

2) use the nvidia installer and it asks to create a modprobe.conf file 
to blacklist
the driver. I said yes thats what I want. I verified the file being 
present and rebooted.
The driver is still loaded "lsmod | grep nou" still showed it present.

3) I tried "rpm -e xorg-x11-drv-nouveau --nodeps". This seeming worked 
however
the files for nouveau were still present. find / | grep nouveau showed 
driver files and more

So - anyone know how to get this off of my machine???
I thought the "-" in the kickstart package section would work, but no.

Thanks so much for any thoughts.

Hi Markus.

Thanks for that detailed explanation.

I've checked the /etc/init.d/mysqld file, and like you say, 
it's the mysqld script itself, using the --user=UNKNOWN_MYSQL_USER
option to test the mysql server is up and running.

So at least I know what is causing this error, and the 
reason for it:

TIMEOUT="$STARTTIMEOUT"
while [ $TIMEOUT -gt 0 ]; do
   RESPONSE=`/usr/bin/mysqladmin --socket="$socketfile" 
--user=UNKNOWN_MYSQL_USER ping 2>&1`

Re: [CentOS] OT: Linus Torvalds delays Linux 3.0 launch due to a subtle bug (fwd)

2011-07-21 Thread Geoff Galitz


And more over, there is nothing earth-shatteringly new in the 3.0 kernel. 
Linus said during the last kernel summit he wanted to change the versioning 
scheme to make it easier for various developers in different realms to track 
version changes.   Don't expect anything super-cool for us on the 
sysadmin/user side as a direct result of the 3.x kernel.

Of course, incremental changes are usually welcome for stability and device 
driver support.

So?  The delay mentioned doesn't impact the CentOS kernels at all.
Features will be backported when he releases 2.6.3X, err, 3.0 as needed.

People that are interested in following kernel developments have a
wealth of resources on the net to make use of, both in the form of mailing
lists and also web sites, forums, etc.

There has been a great deal of off-topic noise on this list in the past few
weeks, of which this is only the most recent example.  It's becoming
more a time sink and less a useful source of information.

How about this list return to _CentOS_ _specific_ discussions?

I'm pretty sure that the elrepo driver is the binary driver.

Thanks Rainer.

The dilemma is whether to upgrade from 5.6 to 6.1 or stay with 5.x as
more 5.x versions (5.8, 5.9, 5.10 etc. might be possible). For me the
only negative aspect of 5.x is old kernel 2.6.18 whereas 6.x is 2.6.32?

Is there any easy method of discovering Red Hat's 5.x intentions
post-5.7 ?

Will the Centos volunteers, who do a marvellous job, be willing to
convert any future 5.x versions in addition to the 6.x versions,
effectively giving them a double workload in addition to their normal
full-time paying-jobs ?

There were two versions of RHEL that were supported, 4.x and 5.x. For a 
short time, there are three (4.x, 5.x and 6.x). But in February 2012, 
4.x support will end, and there will again only two versiosn to support.

I don't know if there will another 4.x (4.10) release after 4.9.

If the server hardware is really identical including disks of the same sizes, 
the fastest way to roll them out is probably clonezilla, which has the big 
advantage of being mostly agnostic toward the target OS.  You can try it out 
with the bootable iso, using sshfs or nfs to connect to network storage for the 
image.  If you like it, set up the drbl server to pxe boot into it.  It is rpm 
packaged, but I ended up using ubuntu on the server because it used to only use 
the server's kernel on the clients and I needed something newer than Centos 
provided for windows machines.  Now I believe you  can configure it to pxe boot 
the image from a current livecd even if you run it on a different server. 
Besides the ability to clone windows and other OS's, it also is good for 
snapshot backups of systems (if you can take them down for the copy) and it 
duplicates everything, including any local installs and config edits.

I don't see how this is a dilemma at all.  If your servers are
installed with the 5.x series, they would and probably should continue
to run using the 5.x series unless they suddenly can no longer perform
whatever tasks you need of them.  If the kernel/OS is meeting all of
your needs, why does the version number matter?

As long as Redhat has committed to support 5.x, you will continue to
get updates for it.  RHEL5 will be supported in some way until 2017.

New major versions of RHEL/CentOS should be viewed as completely
separate lines of product, as opposed to one being a direct upgrade of
the other.

Jul 20 09:41:08 Erased: xorg-x11-drv-nouveau

Is this pure WinXP_64 software RAID or BIOS-assisted 'fakeraid'?  If the
latter, go into the BIOS and change its settings from 'RAID' to 'AHCI'
or other 'native' SATA mode.

The only other thought would be to use a Live CD to clobber the disks
(eg using fdisk or 'dd if=/dev/zero of=/dev/sda' or something). It might
also be possible to get to a shell process with Alt-F2 in the installer
and using fdisk, etc. to clobber the disks -- do this *before* screen
where it asks about partitioning, etc.

The driver rpm depends on all the specific driver RPMs.  The 0 byte figure is
because the driver RPM contains no files.  But it means your kickstart (and
the default install groups) can have xorg-x11-drv and doesn't need to be
updated everytime they add a new driver (which'd be pretty annoying).

If I'm not mistaken, CentOS at one point was providing 3.X, 4.X and 5.X. 
3.X ended at the EOL as set by upstream, just as it should and just as 
CentOS has stated in their policies/commitments. I expect that 4.X will 
follow that same path, will all updates/upgrades done until the 
predefined EOL, again as set by upstream. 5 and 6 should go down that 
same path. So, look to upstream for EOLs on your version of CentOS and 
expect to do a rebuild of your system at that point. This is one of the 
beauties of how upstream operates and what CentOS emulates. Rest at ease.

If upstream holds true to its aimed for goals, I would predict we might 
see 4.11 or even 4.12 before it goes EOL. But that is just a guess based 
on quarterly updates that sometimes aren't exactly out on the third 
month. Gee, I have a bit of work to do. I think I still have like 4 
version 4 systems running. One will be moved to 6 over the next couple 
of weeks... the rest are easy in comparison.

So, erasing the RAID signatures with "dd" in addition to changing the

[CentOS] Experience with Centos running off usb-stick(s)

2011-07-21 Thread Dennis Jacobfeuerborn

Hi,
I'm trying to build a redundant duo of firewalls/routers/gateways and I'm 
thinking about not putting any disks in them and instead using a usb-stick 
raid-1 as storage.
Has anyone any experience with this? Since the machines will be running 
pretty much only iptables, conntrackd and keepalived there is not going to 
be a lot of disk activity going on and the plan is to do all the logging on 
a remote machine which should reduce the write activity on the sticks to 
almost zero during normal operation.

I've already created a fairly minimal kickstart for such an installation 
but I'm wondering if there are any opinions out there on whether this is a 
feasible approach or if there are any gotchas I'm not aware of.

Regards,
   Dennis

I wasn't referring to pdsh/pdcp; I was referring to pconsole.  The 
reason I said complementing is that sometimes it is good to have 
stuff under a configuration management system like cfengine/puppet,
but sometimes you need to run ad-hoc commands, in an identical 
fashion, on lots of similar machines, which pconsole is good at
(subject to the caveats I previously mentioned).

I made no comments on pdsh/pdcp at all, and make no claims on where
it fits in the spectrum.

[CentOS] There is no One True Solution

2011-07-21 Thread Devin Reade

Folks, in many recent threads this pattern has been happening:

   OP:   Any suggestions on how to do ?
   Responder 1:  Look at .
   Responder 2:  Look at .
   Responder 3:  Look at .
   Responder 4:  It doesn't work for me / I don't like that / it's a 
 stupid solution / etc

   

There's nothing wrong with comparing / contrasting different solutions,
but can we please try to remember that every circumstance is different
and that just because someone suggests a solution it doesn't mean
that it's the best for everyone?  Ultimately, only the OP will be
able to figure out what works best for him but having alternatives
can help him get there.

IMNSHO we, as professionals, should have lots of tools in our toolboxes,
understand their pros and cons, not only in isolation but as they 
would apply in the different environments in which we find ourselves.

If you have observations about a solution based on experience by
all means share them (but please qualify the circumstances in which
they apply).  If you don't, file the solution away in your meatware
for future reference.

But if you hear about a solution and it doesn't seem like a good fit
for your particular circumstances, and you're not the OP, can we
please stop hearing the "but it doesn't work for *me* in these
slightly different circumstances" comments?

[CentOS] centos6 not using /etc/gdm/custom.conf

2011-07-21 Thread Jamieson, Stephen CTR Navair, 5.4.4.4

In CentOS5 you were able to create a server section in /etc/gdm/custom.conf 
such as

[server-Standard]
name=Standard server
command=/usr/bin/Xorg -br -audit 4 -s 15 
chooser=false 
handled=true
flexible=true
priority=0

After this change, Xorg would run with the -br -audit 4 -s 15 options. 

Unfortunately in CentOS6 this is not the case. It completely ignores anything 
put into custom.conf as far as I can tell.  It appears to run with -nr -verbose 
-auth -nolisten tcp by default.  Is there any way to modify this?

Stephen Jamieson

Perhaps by not storing so much stuff in it?  That, or adding more RAM.
Seriously, if you're going to fill up a large portion of your available
memory with a ramdisk, demands for memory are going to have to be met by
pushing pages out to swap space.  By default, a ramdisk can grow to up
to half of the available RAM after the kernel has been loaded.  If
programs and I/O buffers need more than the other memory you have
available, what option is there besides swap?

I should probably have just answered `man taskset`, but the below got
typed too quickly.

"what option is there besides swap [to disk]?"

Compcache, Compressed Caching for Linux?

But last I read, it needed a newer kernel than was in 5.x.
So no I have not tried it. :)

 From elrepo.org,

yum install kmod-nvidia

will take care of everything for you, and because it's a kABI-tracking 
kmod package you won't need to rebuild the kernel module for each kernel 
update, and yum will automatically take care of future nvidia driver 
updates for you too.

A word of warning - there is a bug [1,2] in 6.0 that means installing 
kmod-nvidia from a kickstart file will *fail* so I would advise 
performing your install and then manually installing kmod-nvidia 
immediately afterwards. Alternatively there is a workaround in the 
elrepo bug report [3] should you really want to do this from a kickstart 
script.

Hope that helps.

I just installed CentOS 6 on Monday and at least the daemon section was honored:
I have this:
[daemon]
AutomaticLoginEnable=True
AutomaticLogin=mythtv
TimedLoginEnable=true
TimedLogin=mythtv
TimedLoginDelay=30

And my MythTV account logs in without delay on boot and after 30
seconds if you logout and leave the console idle.

In later Fedora releases, GDM has become less and less functional:
configurability has been removed, more so as releases occur. From my
(known to be flaky) memory, that includes the ability to turn off the
silly list that exposes usernames right on the login screen, the ability
to assign your own wallpaper to the login screen, among other things.

In some releases you can hack your way around whatever the missing
feature is that you're missing by using gconf-editor, in others you can't.

So, my guess is that RHEL/Centos 6 has inherited the later Gnome
"features" that have removed the feature you want.

Actually I am not storing too much stuff in it since there is plenty of free 
memory. That was the point of my earlier posts asking why swap when there is 
plenty of free memory. 

Correct me if I am wrong, but I believe behavior is unused files in /dev/shm 
use swap space? I want to make it so it does not do that since it slows the 
system down 
and since there is plenty of available free memory.

And that makes it inappropriate for US gov't work (violates official std),

Ah, yes, creeping M$-ism. Just like the urge to make stuff look more and

[CentOS] Using shell variables inside the ftp client

2011-07-21 Thread James B. Byrne

I have a script that opens an ftp connection to a non-*nix system. 
I desire to change directories on the host system using a shell
variable to set the cd directory.  However, I cannot seem to
discover how this is done.

I have tried this:

TARGET=ftp-pickup

ftp
.  .  .

cd $TARGET

This gives the following error:

550 Failed to change directory.

I am using shell variables (put $TEMP_TXFR_FILE $OUTPUT_FILE)
elsewhere in this ftp session as arguments to get and put statements
and I have no problems.  Is there some reason why I cannot use shell
variables as arguments to the cd command?

I am aware the $ is used to invoke .netrc macros but I have none
defined.  In fact I was somewhat surprised, albeit pleasantly, when
the ftp client accepted shell variables as arguments in the get and
put statements.

Is there a way to dynamically define the target of a cd command
inside an ftp session?

Re: [CentOS] Memory Usage in Top and System Monitor‏


Sorry, I am new to using the mailing list. I put RE: in the subject line 
thinking it would stay in the same thread but not sure why it did not work. So 
I turned of daily digest to reply and replying directly now. Apologies if this 
reply did not work.

Check the FTP configuration file on the remote server. There might be a
block to stop you moving-out of your log-on FTP directory.

VSFTP on Centos has this capability so too, I imagine, has other FTP
servers.

Um, you're new to email (or only have used Outlook...). Hit  will
do that. Don't manually put it in.

Those options are no longer supported in GDM. I think that they were
removed with GDM 2.24 (at the latest, probably 2.22) and C6 is running
GDM 2.30.

You can use

[security]
DisallowTCP=false

in "/etc/gdm/custom.conf" to override the "-nolisten tcp" but I have
no idea about "-br -audit 4 -s 15".

"chooser=false" and "handled=true" are the default (as far as I
remember what they stand for!); no idea about "flexible=true" (I can't
remember what it stands is for!).

It's pretty weird that RH didn't change the GNOME upstream default of
exposing the usernames. I presume that RH doesn't care about the
desktop enough in an enterprise setting. It's easy enough to change
with a gconftool-2 invocation but "even" Apple allows its users to
switch from a "click on an icon/name" login to a "type your name"
login within the OS X GUI. The GNOME developers' choices are difficult
to understand, IMHO.

A ramdisk does not consume any memory at all until you store stuff
in it, and then it uses only such memory as is required to hold its
current contents, i.e., it will shrink again if stored files are
truncated or removed.  From your comment, I presumed you knew you
were actually storing data in /dev/shm.  If you are not, then you
will have to look elsewhere to see what is sometimes consuming a lot
of memory.

Re: [CentOS] Memory Usage in Top and System Monitorþ


Like I said I turned off daily digest to get the individual emails so I could 
"Hit" . (rather than copy/paste from here and RE: in subject line).

So do you know how to stop ramdisk from swapping to disk when there is plenty 
of available memory? I was using /dev/shm but created my own which I suppose is 
the same thing and have the same issue.

mkdir -p /media/ramdisk
mount -t tmpfs -o size=2000M
mount -t tmpfs -o size=2000M tmpds /media/ramdisk
