You can host an SL context on the DVD following:

You can also use the attached script to build a DVD.

I need help filling in the steps.

You've got the right steps.  Using rsync is probably the easiest way to 
mirror a repo.  If I recall, examples are on the SL website, and I think 
Nico has posted links to the tools he has written as well.


Once you have the repo mirrored, you can burn it to DVD or copy to USB 
drive, etc.


On the offline machine, you need to edit or create a new file in 
/etc/yum.repos.d/.  It is probably easiest to copy an existing one if 
creating a separate, new repo.  Give the repo an alias in the [] and set 
the baseurl=file://path/to/repo/.  This is the directory containing the 
'repodata' directory.  If you have enabled=1, it will catch it with 
standard yum.  Otherwise you will need to pass 
--enablerepo=alias-you-used to yum with your commands.

It looks like sa_family_t has been morphing over time.  In SL5, it is 
indeed defined in linux/socket.h.  In SL6 I find it defined in 
bits/sockaddr.h.  In SL7 it continues to be in bits/sockaddr.h, but 
there is also __kernel_sa_family_t defined in linux/socket.h.


Try adding bits/sockaddr.h to your includes.

I haven't had much time to work with SL7 yet, but isn't it the
case that there is no xorg.conf by default?  Try just renaming the
nvidia generated one and see what happens.  I think the X server
attempts to autodetect settings, which has gotten fairly reliable
over the years for the most common setups.

-Mark


That is my understanding. In SL7, there should be no xorg.cong file by
default. In fact, |xorg.conf| is marked as deprecated in EL6, but will
still be used if it is present. Graphical settings are supposed to be
automatically detected and configured by the X server.

Akemi


Precisely the problem.  The Nvidia X11 driver package seems to have
"hardwired" some version of the Nvidia (not noveau) driver into the
system.  How does one find this and revert to "stock"  for an Intel
graphics driver or for some more generic VGA style driver?   If I list
the installed RPMs and remove the Nvidia RPM will this address the issue?

My laptop (upon which I am now working) has a laptop Nvidia "card". Thus,

rpm -qa reveals

nvidia-x11-drv-352.41-1.el7.elrepo.x86_64

when I do the same on the workstation in question, I presume I will find
a similar (but perhaps different numbered) nvidia-*-el7.elrepo.x86_64;
if I rpm -e the version on the workstation, will this action force a
return to "default/stock" or must I do something in addition?

Yasha Karant



Uninstalling both the kmod-nvidia and the nvidia-x11-drv should do the 
trick.  It may leave behind the xorg.conf for you to manually remove, 
depending on how the rpm was configured during build.


It is the kmod-nvidia module which does the nouveau blacklisting using 
/usr/lib/modprobe.d/blacklist-nouveau.conf.

Re: a year later - CERN move to Centos - what are we doing?

[Mark Stodola]

Since this is becoming a top-post thread, I will continue the trend.

CentOS does not offer a support contract like RHEL.  Why would a company 
compete with itself?  It is essentially a community supported release of 
RHEL, just like SL.


Of course, some one please correct me if I am wrong here...

This is not a new topic, and was discussed at length when RedHat 
announced the acquisition of CentOS and changes to the build process. 
To my knowledge, the SL team had discussions with the CentOS and RedHat 
people on how to move forward.  The SL team decided to continue as a 
complete separate distribution instead of become in extra 
repository/site for the foreseeable future.


One of the key features I like about SL is the ability to stay on a 
specific point release and still receive relevant updates.  There are 
probably several other reasons Connie or Pat could elaborate on as well.


In the end, it is up to personal/company preference with any 
distribution you chose to use.  That is part of what open source is 
about.  Arguing for distribution usage/mergers doesn't really do 
anything productive here in a users' mailing list.

hi,
after my first post I made a move, I should say a smaller rather, I

Instructions to do that I'm sure everybody can easily look up, just
one tiny manual intervention was needed above what is already covered
by a doc on Centos website.
But most importantly nothing broke, all the usual servers, web, mail,
other net related services including HA carried on seamlessly.
Like I said earlier, and everybody knows, a lot, a lot is already
shared, differences boil down to maybe a philosophy behind each
organization responsible for each snip-off, some organizational and
administrative processes, protocols.
Slight advantage seems that Centos offers, but expected as they are
closer to the source in the lifecycle supply chain, is higher revision
of some rpm packages, I see I get slightly newer kernel for example, etc.

If I was to voice my opinion out - and scientific devel & other
responsible culprits are listening - then I say: go for it, get
together, merge userbase, share devel jobs, duties, etc. Merge/share
or even better, tell Redhat we want to use their, shared by all, bug
reporting system.

I've decided, I'll be moving over to Centos, gradually but surely.
Note, one thing to remember if you did SL -> Centos, afterwards, is
yum repos, make sure what you have enabled there.

that is licensed for free for home use -- presumably meaning single 
user unless one really must work from home for this use.


Note that this application does not support Linux.  Hence, my plan 
is:  under SL run VirtualBox running MS Win 7 pro running the above 
application, but save all of the produced files on the Linux side 
using VirtualBox shared folders.  Many of my colleagues here do not 
use MS Win as the primary OS environment; most use Linux or MacOS X 
with open system extensions (e.g., fink).  The colleague who suggested 
the above application is using MS Win on his workstation.


Has anyone had any experience with this sort of scheme or this 
application?

I would just pick something that seems to have merit and _try_ it.  At 
worst, it doesn't do what you intended and you go find something else to 
try.  I am in a similar situation (mail migration) and am planning on 
trying Chris's suggestion of imapsync.


Setting up an entire virtual machine seems a bit overblown for email 
save/restore.  Also, don't get too caught up on the licensing.  If you 
are doing it 1 time for a handful of users, I wouldn't worry too much.  
If you are going to use it on a regular basis, continuously, then the 
licensing becomes much more of an issue.  If you look at the licensing 
plans, you can see it is bracketed by user count and on an annual basis, 
targeted as a long term backup solution.


My advice, if you are using linux, find a linux solution.  There are 
dozens of scripts/programs out there to do this, just pick one and 
experiment.

Re: SL7 install fails on EEEPC-100HD

Hello,

from an usbkey created with
dd if=SL-7-x86_64-Everything-Dual-Layer-DVD.iso of=/dev/sdc bs=512
installation request goes on on most of x86_64 computers.

But on EEEPC-1000hd ( celeron processor, 900mhz), installation process
stops at boot request
boot:
and following messages are issued:
boot:
Failed to load libcom32.c32
Failed to load COM32 file vesamenu.c32

Is it completely impossible to run the boot process on EEEPC-1000hd
because it's known as a 32bits machine?

Can something be done to overcome this failing step?

Should I come back, to
SL-6.6-i386-2014-11-05-Everything-DVD1.iso
SL-6.6-i386-2014-11-05-Everything-DVD2.iso
?

Thank you for your help

Charles




Charles,

You are correct, the 1000HD uses a Celeron M 353 which is a 32-bit only 
processor.  SL7 is only available as a 64-bit OS.  You will have to 
stick with SL6 in this case or switch to another distribution that still 
builds for 32-bit.


I'm a bit sour over TUV's choice to drop 32-bit, but you have to roll 
with the punches.

Since it's commercial software, maybe you could ask *them*?
I already have.  As Corel (which bought Bibble -- strange -- if 
corporations are people, and corporations can buy other corporations, 
why cannot non-incorporated real human people buy other 
non-incorporated real human people -- perhaps because corporations are 
not people but merely engines of avarice) effectively was bought by 
Microsoft a number of years ago, their technical support for Linux is 
not superb.  Otherwise, Corel would keep (as does VirtualBox owned by 
Oracle, a parent corporation that competes with Red Hat for EL 
for-profit support) versions around that are in fact directly 
compatible with most distros. Interestingly, the IA-32 version (32 bit 
linux) runs fine under IA-32 SL 6x.


Speaking of which, is there any other workflow package that works as 
well or better directly under Linux (I do not mean Photoshop under MS 
Windows under VirtualBox under Linux -- I do mean native)?  I have 
tried gimp, but the import facilities for imaging vendor proprietary 
image formats (raw, e.g., Nikon NEF) is not as effective.  I do not 
run Mac OS X (a typical image manipulation environment) because none 
of our primary machines (both fixed workstations as well as laptops) 
are sold by Apple and thus it is software piracy in the USA to run Mac 
OS X on such machines (Apple will not sell a license for Mac OS X for 
non-Apple machines ) -- otherwise Mac OS X with fink or the equivalent 
might be a solution.


Yasha Karant


This might be a case where another distribution will fit your needs 
better.  Does Corel have a list of supported OSes you can reference?

is [Desktop Entry] part of the post install script?


Yes, if you look close, the lines right above that call xdg-open, and 
are echoing the [Desktop Entry] lines into a file (using the ).  It is 
basically creating a desktop icon entry in a common location.


/bin/echo -e #!/usr/bin/env xdg-open
[Desktop Entry]
Type=Application
Name=PDF Studio 9
Exec=/bin/sh \$I4J_INSTALL_LOCATION/pdfstudio9\
Icon=$I4J_INSTALL_LOCATION/.install4j/pdfstudio9.png
  $I4J_INSTALL_LOCATION/pdfstudio9.desktop

That is all one line of a command essentially.
It looks like the script just makes a few symlinks and ensures the newly 
created desktop icon is executable.
The rest is just unpacking jar files, which I'm not as familiar with as 
I haven't touched java in close to a decade.  It all looks straight forward.

Hi Mark,

Do you know how to do the reverse of the cpio extraction?
In other words, how to make it back into an rpm?

-T


You need to use rpmbuild and write a small SPEC file.  It's a bit much 
to explain in email.  I suggest grabbing this guide to get started:

https://www.gurulabs.com/downloads/GURULABS-RPM-LAB/GURULABS-RPM-GUIDE-v1.0.PDF

It's not hard, and if you grab a SPEC from another simple source rpm, it 
shouldn't take long to have a usable output.  Basically, you have to tar 
up the files you extracted, create the spec w/ the 
postinstall/preuninstall script sections, and tell it to go.


There are probably guides from TUV that have best practices for naming 
and locations, but you aren't required to follow them, especially for 
something this trivial/personal use.

Learning the art of building RPMs is a valuable skill, no time like the 
present to learn.  Once you know what you are doing, you can have a nice 
environment setup to build things.  A lot of people use 'mock' to ensure 
clean build environments (chroot), but like I said before, not necessary 
in this case.

It is an unfortunate change, yes, but I prefer to give Red Hat the
benefit of the doubt as far as motivations go, since they could close
it up completely like SuSE has with SLES and SLED (OpenSuSE is SuSE's
Fedora, so it doesn't count).  And SuSE is completely within its
rights under GPL to do how they are doing; this is not a jab against
SuSE, since SuSE has also done and is doing a lot of great work for
open source.  (Of course, since I haven't looked for publicly posted
source for SLES in a while, they may have posted it since I last
looked and I just don't know about it.)


I am glad you agree that Red Hat now moving closer to what SuSE is doing
is unfortunate and not welcomed by the community(*).

(*) Where community in my definition excludes people on Red Hat's
payroll ;-)



Although this discussion seems interesting, I see the same points being 
reiterated.  I don't see how any of this is going to change anything 
though.  RedHat and CentOS are moving forward whether we like it or not 
and the SL development team are doing what they can within those 
constraints.  If one needs all that integrity and vetting of the source, 
go fork over the money for a license.

That is correct, SL and TUV do not support secure boot at this time.

I'm sure a more up to date list can be found with moderate searching.

Evidently, the current answer for SL is that it is not UEFI Secure Boot

depending upon the quirks (or proprietary generosity) of the actual BIOS

The only hardware that does not permit secure boot to be disabled is
arm based Windows. The Windows logo requirements at at work here.



If Linux cannot handle this issue, then Linux is finished on all generic

At the moment Fedora, SuSE , Ubuntu all can handle secure boot. It is

Hi Mark,

The frustrating thing is that I have no problems printing
from anything else. I can print an envelope just fine
from Wine/Word Pro, which also uses CUPS. Other programs,
portrait or landscape, print just as it is told.

Anyway, I opened up the following with Red Hat:
https://bugzilla.redhat.com/show_bug.cgi?id=977976

Maybe, someday, I will be able to print an envelope
through LO.

Thank you for your response.

If you have the time and patience, you can look into turning up the 
debug/log level of cups to see what is going on between the programs. 
You can also intercept the print queue contents by leaving the spool 
enabled but the printer disabled.  With enough poking, you should be 
able to pin down where the problem exists.


I am guessing (not sure) that most word processors generate postscript 
and send it to CUPS.  You can compare the postscript generated in the 
spool from each of your programs to see how they differ.  It may be 
worth while to open the postscript in a text editor to see if there is 
other meta-data that could be affecting the outcome as well.

I'm not familiar with LAPACK myself, but if you are unable to locate a

be retrieving the srpm (source rpm) and modifying the spec file to use 
the newer source package and rebuilding.  You might run into dependency

You may need to change /etc/fstab and /boot/grub/grub.conf, if the
partition layout is different or the files use UUIDs. In the latter
case, I just change to partition names (e.g./dev/sda1).

Then run grub to install the boot loader:

grub
root (hd0,X)
setup (hd0)

This works great as long as the hardware is similar enough that the
initrd/initramfs still works. Otherwise, there's an extra step to
regenerate it, which I can explain if people want.

image onto the remaining machines one hard drive at a time.

Let A represent the operational (clone source) machine, and Bhd a
target hard drive. The hard drive on A is /dev/sda, call it Ahd. A is
shut down power off. Bhd is installed into an available bay on A, A is
booted, and Bhd appears as /dev/sdb in A. Using dd on A, clone
/dev/sda to /dev/sdb . Mount on A the partition of /dev/sdb that
contains /etc (there are no end user home directories -- only home
directories are those of the system administration users). Using a
text editor (e.g., vi), modify the /etc/sysconfig/net*
scripts/directories, as well as /etc/hosts. for the name and IP
address of machine B that will contain Bhd (resolv.conf will be the
same -- all of these machines are in the same DNS subzone, same TCP/IP
subnet). Iterate through all of the target workstation hard drives. As
there are no other distributed services running, this should suffice.

Shutdown A, remove Bhd, install Bhd into B, boot B upon which Bhd
should appear as /dev/sda . Done.

Is there a better method in terms of software? At this time, I do not
want to setup a remote image server that effectively will download the
full image of Ahd onto Bhd over a network, nor do I want to make a
custom install DVD as we only have a small number of workstations to
clone, not, say, one hundred.

I do understand that if Ahd and Bhd present different bad blocks to
the OS, and these are not hidden by the intelligence on each
individual hard drive, then dd may not work. However, the drives
already have been surveyed and the bad block situation should not be
an issue.

A related question (that was partially addressed in a different
thread): is there a way to remove/disable Network Manager and use a
traditional static configuration? On a laptop that needs to move
within the field from one 802.11 network to another, with a different
DNS zone and TCP/IP configuration, Network Manager provides similar
ease and functionality to the end user autoconfiguration applications
that are used under Mac OS X or modern MS Win. This is unnecessary and
in some sense dangerous for static workstations that need no such
dynamic configuration.

My thought was to find the RPM that installs Network Manager and
simply uninstall it, either via yum or a simple rpm -e command. Is
Network Manager too deeply ingrained in current EL6 (using TUV
compliant model) to make this feasible?

Yasha Karant



You can use g4u (Ghost for Unix) or g4l (Ghost for Linux) to image and 
back up disks over the network.  Usually using FTP.  There are other 
fancier utilities such as Clonezilla that may also work well.  Most have 
bootable media to get it on the network and a few clicks/commands to get 
the disks cloning.

requires the additional manual steps you outline. dd of an entire hard
drive does clone the MBR and also effectively does the formatting step
of each partition (we are not using logical volumes, but old fashioned
distinct partitions).

You also presume a high throughput network, depending upon the size of
the tar file image, as otherwise the time for getting the tar image can
be substantial. Whilst the network here is adequate at switched 802.11
100BT, with only limited segments at 1 Gbit/sec or higher bandwidth, the
actual throughput -- as measured -- can be less than 1 Mbit/sec causing
substantial delays. These workstations are NOT on a 1 Gbit/sec segment,
but only at 100BT, and we (locally) have network issues. As the
workstations have physical security locks and are cabled through raised
flooring, physically moving the machines to a location with a proper 1
Gbit/sec LAN segment, bypassing the local university security
implementations, VLAN segments, etc., is a significant amount of
physical work.

Am I misstating your methodology?

I've done cloning for many years with tar:

On the source machine, boot from an SL live CD and mount the source's

cd /mnt/wherever

Then, on the target, boot the live CD, partition the disk, create the
root filesystem and mount it. THen untar the contents with something
like:

cd /mnt/wherever
ssh someuser@somewhere cat mysystem.tar | tar -xpSf -

You may need to change /etc/fstab and /boot/grub/grub.conf, if the
partition layout is different or the files use UUIDs. In the latter
case, I just change to partition names (e.g./dev/sda1).

Then run grub to install the boot loader:

grub
root (hd0,X)
setup (hd0)

This works great as long as the hardware is similar enough that the
initrd/initramfs still works. Otherwise, there's an extra step to
regenerate it, which I can explain if people want.

As there are no other distributed services running, this should suffice.

should appear as /dev/sda . Done.

Is there a better method in terms of software? At this time, I do not
want to setup a remote image server that effectively will download the

Re: What is the correct way to set up a dual boot system for CentOS 6.3, or SL 6.3, and Windows 7?

After numerous searches on how to setup CentOS 6.3 and Win7 to dual boot
I turn to the readers of this forum for help...

I suppose my question is quite simple:

What is the correct way to set up a dual boot system for CentOS 6.3, or
SL 6.3, and Windows 7?

I have tried several times, with several variations, but run into the
same problem: After installing Win7, then CentOS, the machine boots
straight into Win7 and no grub menu appears...

I have a pretty new system that I built in Nov 2012: i5-2500K, Gigabyte
GA-Z68XP-UD3 mobo, 8GB RAM, eVGA NVIDIA GTX 560 card, and two 1 TB SATA
drives.

My first attempt was to install Win7 on drive 0 then install CentOS on
drive 1, with grub installed in the /boot partition which was on
/dev/sdb1. Apparently there were some issues with this due to Win7,
UEFI, etc. I didn't really understand all these problems so I tried again.

My second attempt was to try to disable the EFI stuff in BIOS and
install WinXP, then install Win7 over this to avoid the system restore
partition, and EFI issues etc. then install CentOS over this, again
installing grub to /boot, which was /dev/sdb1.

I noticed the default location for grub was /dev/sda, which is the
windows disk... Would this not hose up the windows install?


I believe your problem is right here.  Both of your previous 
descriptions installed the boot loader to a partition on the second 
disk.  Most BIOS will boot from the first MBR it finds.  This is 
typically the MBR of disk 0.


Your first attempt looked good, but you needed to install the boot 
loader for CentOS (SL, TUV, etc) to /dev/sda (notice no partition).  If 
the installer doesn't catch it, you will have to manually add in a chain 
loader for Win7 to the grub menu.  This is a quick text file editing. 
Examples can be found doing a web search along the lines of 'grub 
windows 7 boot entry'.


A typical dual boot should install Windows _first_, then any linux 
distributions.  This allows the later boot loaders to locate and add 
entries for the previous operating systems if possible.  The Windows 
loader can be a pain to get other operating systems (such as linux) to 
work, but it is possible.  You'd have to extract the linux boot loader 
from the disk into a file, put it on the windows partition, and manually 
add entries to the NTLDR configuration.  At least, that is how it was 
many years ago when I did it with NT4 and using lilo.




I have set up Windows/CentOS dual booting before, but not on this
machine, and not with CentOS 6.3. Any help would be appreciated more
than you can imagine...


I have been a CentOS user for a while, but I am intrigued by SL, and
would definitely jump ship to SL if I can get it dual booting with Win7...

Revisor is the recommended tool for SL6.  You always have the option of 
rolling by hand.  I use a set of modified scripts to roll custom SL5 
images based on the documentation on the SL's website and from searching 
the web.  If you simply want to customize the packages, you can make the 
necessary changes, rebuild the repo data, update the comps files, and 
build the image.


Remember, SL and TUV are _not_ bleeding edge like Fedora.  Just because 
the bleeding edge calls something old doesn't mean it is garbage and 
useless.  It just means someone has come up with a new/different way of 
accomplishing the same task.

You might want to try the various atl drivers from ELrepo (elrepo.org). 
 They maintain current drivers for a lot of devices not generally 
supported by TUV.  I think you'll want kmod-atl2.  If you find that none 
of the ELrepo drivers work, it might be worth contacting them to get the 
correct one built and added to the repository.

If the connection is still active, you can use a combination of 'netstat 
-na' and/or 'lsof -nP -i4' to find the process owning the connection. 
If it isn't, it will be difficult to track down without fancier 
logging/capturing tools.  You mentioned remote mounts, but not what 
method (CIFS, NFS, etc).  If it is NFS, pseudo-random ports are chosen 
for the client connections and may be your culprit.

Probably no time soon, since it apparently requires newer versions of

http://docs.xfce.org/xfce/building
Xfce 4.10 requires Gtk+ 2.20 and Glib 2.24

SL6 has 2.18 and 2.22.


This sort of thing is why you exchange cutting edge for stability. Its
the same issue with moving KDE ahead to  4.3: a lot of the core distro
would have to go along with it.

The dependency breakages (or, at a minimum, package rebuilds) required
are a hard enough maintenance problem that its better to just spin off a
new distro than to deal with rifted library problems. Distros get hard
to maintain pretty fast, which is why most distros don't make it very far.

Since both XFCE and KDE aren't part of SL or TUV's distro but come from
EPEL (and probably other repos) its impossible to expect the SL team to
decide to fork the entire distro for the sake of one window manager, as
this is completely against their goals.


Just a minor correction, KDE is indeed part of TUV/SL, it just is not 
the latest bleeding edge, as you state.

I would recommend looking into squid or some other filtering proxy.  The 
fundamental problem with using iptables/hosts restrictions is wildcard

up sinking a vast amount of time to resolve.  There are also several 
commercial solutions that can be implemented at the firewall/router

Hi Mark:

I believe you should be able to update the global prefs.js in something like

/usr/lib64/firefox-3.6/defaults/profile/prefs.js

Eg something like

user_pref(browser.startup.homepage, http://google.com;)

Anything in firefox about:config should be able to be set like that globally.


I'm actually trying on FF 10 on a 32bit install.
I've been trying various filenames with those contents (also pref(), 
lock_pref() and lockPref()) in:

/usr/lib/firefox/
/usr/lib/firefox/defaults/
/usr/lib/firefox/defaults/preferences/ (this is where channel-prefs.js 
exists)
I even created /etc/firefox (and a few subdirectories based on a google 
search.
I'm stuck with the file:///usr/share/doc/HTML/index.html, even after 
clearing out ~/.mozilla.


I'm not looking for theoretical replies, but rather someone who is 
_actually_ doing it and has it working.  There must be someone out there 
who's got this worked out on SL/CentOS/TUV.

then I'm
not sure what Networkmanager or the new parallel udev device 
discovery may

be doing... And since 6.1, some (recent Dell) servers have biosdevname
enabled by default. Which makes the first onboard interface em1, for
example :-) The advantage is that this will always match the 
physical socket

labelled 1 on the server.
ksdevice=link works for me when I'm doing an actual pxe boot.  I 
haven't
used the pci=bfsort parameter but the sorting of the names isn't the 
problem

here.  The kernel/initrd.img combo from the DVD seem to be ignoring
ksdevice=link and ksdevice=mac addr.  Regardless of sorting issues 
those
should work if I've only got one NIC with an active link, which is 
true, or

if I specify the mac address of the NIC I'm installing over.

What happens if you use a regular DVD, tab out of the menu, and add
your ks=... and ksdevice=... values to the kernel line?

Don't have a DVD drive on that system.  I built a USB stick from the 
install DVD that's boots correctly.  Tried out Tom's suggestion on a 
different system with only one NIC and everything proceeded as expected.


Tried on the problem system and again it worked just like I want it 
to.  But when using the vmlinuz/initrd.img combo from the install dvd 
manually entered into /boot/grub/grub.conf it ignores the ksdevice 
parameter.  The system boots to the installer but gets stuck awaiting 
a selection of which NIC to use.  Selecting the active NIC and 
everything proceeds normally.


What install DVD are you grabbing the image from?  There was a bug in 
6.0 and 6.1 involving the network interfaces during installation.  A new 
6.1 iso was issued and the fix was in place for the initial 6.2 
release.  Make sure you are at least using the corrected 6.1 image.

Docbook, Publican, docbook-utils?

[Mark Stodola]

Does anyone have any recent experience writing documentation in docbook 
with current tools?
I'm in the process of updating a user manual that I wrote several user 
ago in docbook xml that used xsltproc, fop, and docbook 4.1.x 
definitions.  It looks like I've fallen behind and new tools are 
around.  A search shows that supposedly TUV is using a tool set called 
Publican, but information is scarce.  I also see docbook-utils and 
docbook-utils-pdf as available packages.  Grabbing the latest fop and 
definitions is giving me quite a screen full of errors.  There must be 
an easier way by now.  I'd like to continue to generate html, pdf, and 
ps output at a minimum.


What are people using for a tool chain these days?

My laptop and workstation are operating environment identical except
that my laptop is IA-32 SL6x and my workstation is X86-64 SL6x (and
there are some hardware differences reflected in driver differences).
On my workstation, as root, I can update any of the Mozilla

10.0.2) from within the application. However, on my laptop, this
generally fails and I must download a new tar.bz2 file that I must

what is the reason? Note that my mozilla configuration files between
the two platforms are the same in so far as I have any control over
these (e.g., visitation to different URLs from firefox or seamonkey

mandated by my university or from clean sites).

I have done a cursory check of the mozilla public lists but have found
nothing of relevance.

Thanks for any insight.

Could you start firefox from a terminal, try the internal update
process, and see if any usefull information is given in the terminal?
Sure sounds like a permission problem; but you said you are using root?
You should be able to destroy anything as root:)

Chris


There is no problem in downloading from Mozilla the entire update as a 
tar.bz2 package followed by the manual installation ( tar -vxjf ) as 
root into the appropriate directory.


However, there is a mechanism, for minor release updates (e.g., 10.0.1 
to 10.0.2) within firefox, thunderbird/lightning, and seamonkey 
without the manual unpacking -- the files are updated within the 
running application and the updated instance is invoked at the next 
initiation (restart) of the application.  This mechanism needs to be 
as root if the files are installed in a systems, as contrasted with an 
ordinary end-user, directory.  However, the mechanism fails on one 
SL6x box but succeeds on another; when the mechanism fails, then I 
must used the manual installation method from the tar.bz2 file as 
explained above.


Yasha Karant


I believe Chris is well aware of that.  He instructed you to start 
firefox from a terminal and attempt the update process from within 
firefox (meaning _not_ the tar.bz2) and see if it has any errors written 
to stdout or stderr in the terminal.  It helps if you read the email you 
are replying to.

You should be able to modify the ppd file in /etc/cups/ppd/.  You can

dimensions to the orientation you want.  Restart cups after editing.

The reason for the upgrade is to pick up the security fixes in 2.2.21.
  
This is where TUV's practices can get one confused.  They have a habit

Bill,
I've experienced the same situation over the years.  I simply disable 
kudzu after the initial installation.  It will not affect USB or other 
hotplug type devices as you question (at least from my experience).  I 
have a setup script/rpm that issues a 'chkconfig kudzu off' and go on my 
way.  The only time I've needed to run it again is if I change hardware 
that requires different drivers.  You can then make the changes by hand, 
or run kudzu from the command line on an as-need basis.


For information's sake, kudzu builds, maintains, and monitors 
/etc/sysconfig/hwconf in case you are curious how it determines things.

NetworkManager provides the same sort of services and is widely used

putting it into your computer via a USB stick.  The rpm should be installed
once, and then never needs to be installed again.  In the case of a
distribution such as RHEL, standard practice is to have necessary rpms
installed initially as part of the original system.  It would be somewhat
surprising if that didn't happen with rp-pppoe.


I think I have failed to clearly point out my problem. I know how to
set-up pppoe connection via Roaring Penguin software rp-pppoe as I
have already done so with my Fedora 13 and Ubuntu partitions.
As I am currently installing SL from Livecd which does not come with
that rp-pppoe package. So that I have to download it somehow and then
install it to set up a pppoe connection. That's why I am asking
whether there are any other software/method to set up pppoe connection
in SL?
My confusion increases with googling and after going through RHEL
documents - I have found some suggestions there as how to configure it
with pppd. Just want to know how is it different than the software we
are dicussing rp-pppoe and is there some easy steps to do so.

Re: How to turn off screen saver and DPMS

   Does anyone have any ideas? Is there something that can be added 
to the xorg configuration to prevent the screen from turning off, 
perhaps?


We have been investigating this somewhere in 2008 for a conference 
(FrOSCon) with the aim of providing 2 large conference screens 
directing people to various talks at the entrance (a bit like as you 
can see at airports), but also for the various presentation computers 
in the various rooms.


Obviously, the first year having to provide input every hour to make 
sure they didn't blank was not very much appeciated. (But hey, 
CentOS+ELRepo actually worked on the hardware, in contract to latest 
Fedora and Ubuntu) So our LiveUSB solution that was not designed for 
it, was not tested for this kind of use.


The next year I came up with the following configuration (tested on 
CentOS 5), which worked:


 ### Disable screensaver start
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
bool  /apps/gnome_settings_daemon/screensaver/start_screensaver false

 ### Disable screensaver locking
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
bool /apps/gnome-screensaver/lock_enabled false

 ### Disable screensaver altogether
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
bool /apps/gnome-screensaver/idle_activation_enabled false

 ### Increase screensaver idle time (max 2h, we set to 10h)
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
bool /apps/gnome-screensaver/idle_delay 600

 ### Disable DPMS screen blank on AC and battery
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
string /apps/gnome-power-manager/ac_dpms_sleep_method off
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t 
string /apps/gnome-power-manager/battery_dpms_sleep_method off

 ### Disable Computer sleep when on AC and battery
 gconftool-2 --direct

integer /apps/gnome-power-manager/ac_sleep_computer 0
 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t

 ### Disable Display sleep when on AC and battery
 gconftool-2 --direct

 gconftool-2 --direct 
--config-source=xml:readwrite:/etc/gconf/gconf.xml.defaults -s -t

 gconftool-2 --direct

 ### Other noblank features
 cat EOF /etc/X11/xinit/xinitrc.d/noblank.sh
 echo Disable screen blanking for $TERM and $DISPLAY
 setterm -powersave off -blank 0
 #xset -dpms
 xset dpms 0 0 0
 xset s noblank
 xset s off
 EOF
 chmod 0755 /etc/X11/xinit/xinitrc.d/noblank.sh

It is quite possible some things are redundant, but once it worked I 
wasn't very interested to find those items that were not helping the 
cause ;-)


Hope this works for you. Do let me know if you can improve this scheme !

Kind regards,


This does indeed work! I'm going to hand it off to the rest of our 
software staff for integration and any necessary improvements. If I 
hear of any changes that seem useful to others, I'll certainly pass 
them along.

Just an observation, but depending on what you need displayed and 
interacted with, you could consider running a more trimmed WM or none at 
all.  This would drop all of the gconf settings and leave you with 
simply dealing with the xset/DPMS features of the X server.

You need to have your SPEC file create the symlinks in the
buildroot so that
they are a part of the package, i.e, the symlinks are
owned by the rpm
package. Then when you uninstall or update the package rpm
will
remove/update the symlinks for you rather than leave them
dangling as per
your example above.

Take a look in any relevant package SPEC file from the
distro for examples
of how this should be handled.


Phil,
 thank you. That's what i thought and i took a look @
glibc-2.3.4-2.54.src.rpm. I didn't notice any of the
functionality you
mentioned, which prompted me to write the email.

another question is :
 do i explicitly add the file.version to the %files section
 or just
mention the link ?

Thank you
Andrew


To summarize,  lib_andrew-123.rpm installs the file
lib_andrew.so.123 and creates a symlink to it called lib_andrew.so

Here is how I would handle it:

# make the libdir directory in the buildroot
%{__mkdir_p} %{buildroot}/path/to/libdir/

# then install the lib
%{__install} -p -m 0755 lib_andrew.so.123 %{buildroot}/path/to/libdir/

# then create the symlink(s) as necessary
%{__ln_s} lib_andrew.so.123 %{buildroot}/path/to/libdir/lib_andrew.so


You must also make sure /path/to/libdir is on the ldconfig path if
you have installed to a non-standard path - if not, add it like so:

%{__mkdir_p} %{buildroot}%{_sysconfdir}/ld.so.conf.d/
echo /path/to/libdir 
%{buildroot}%{_sysconfdir}/ld.so.conf.d/lib_andrew.conf

but if you can, it's far easier to just install to /usr/lib(64)

Finally, in %post run /sbin/ldconfig

Your %files section then needs to include all of the above.

Hope that helps


Phil this is very helpful indeed. But the links are created by make 
not by mr (rpm).  So how should we go around this?
 
Andrew


If I'm not mistaken, you should not need to manually link libraries.  
ldconfig should be taking care of this for you, so all you would need is 
the %post entry to run ldconfig with the proper flags after 
install/upgrade/removal.  Assuming it ends up in a standard path, 
otherwise the ld.so.conf entries are needed as well.

Thanks very much indeed. I do some testing with FC15, now that it's out.

  

You guys are all welcome!  Thank you for noticing.  :-)

Nico,

FC15 changed their network adapter naming convention.  See:

http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming

And, they substituted nm-connection-editor for system-config-network.
My eth0 became p2p1.  ifconfig -a will show the new names.  (We will
probably see these changes in EL sometime soon.)



This is not likely. This would be a substantial change to the most
basic configuration tools on the installation media and their default
interfaces. I would not expect to see a feature like that in an RHEL
release, and thus in SL, until after  all the kinks are worked out of
it in Fedora, and RHEL 7 and thus SL 7 is released.
  
This is a feature in RHEL 6.1.  It is disabled by default except on 
certain Dell models.

You can find this in the Hardware Support section of the release notes:

Re: USB over IP programming experience

[Mark Stodola]

David,

This sounds like a job for a terminal server (RS232 over IP).  They are 
very common and easy to work with.  In fact, I'll be on your campus for 
the next 2 weeks (flying in Sunday) to help install an accelerator that 
is being moved.  Part of the installation includes such a device.  I'd 
be happy to meet up and show it to you along with code.  Our control 
system software is written so that you can open a direct device (serial) 
connection or a TCP/IP connection with a simple command line argument.  
This results in minimal code changes.


If you are interested in meeting or want more detailed information, we 
can take it off-list.  My contact at Vanderbilt is Mike McCurdy, 410 
24th Ave S.


Cheers,
Mark

Install the kmod-nvidia and associated packages from ELRepo.  I'd take 
nvidia over ati under linux, the 2D performance from the ati driver is 
horrible, especially under multiple monitor configurations.  The binary

I try to use Intel NICs as often as possible.  If the standard SL kernel

Re: Network Shared close periodically

[Mark Stodola]

This could be a simple matter of firmware for the USB wireless 
adapters.  Have you tried removing the USB adapters for a few seconds 
after linux has been shutdown, then booting windows?  You could also 
unplug them while windows is running and then replug to load windows' 
copy of the firmware.  I've had adapters that refuse to work between the 
2 OSes because of mismatched driver/firmware combinations without 
removing power from the adapter.  I imagine there is some flag or device 
ID change that occurs once the firmware is properly loaded, causing 
subsequent loads to be ignored.  I've seen this with JTAG programmers as 
well.  You may be experiencing this, only in a more subtle manner.

It's a serious problem for me because the disconnection of a mapped

Looks like a DRI/GLX issue at first glance.  I've had very good luck 
with the ELrepo packages:
kmod-nvidia, nvidia-x11-drv combination.  Maybe you are missing the 
kernel module in the first instance.

Re: Need help recovering SL4 /boot (not backed up)

[Mark Stodola]

Greetings SL fans,

Sorry for the length of this post, but I'm hoping someone can come to my
rescue and want to provide sufficient context.

Recently I had a hard drive failure on a Sun X4600 box running SL4.8.
The box has four drives; the drive that failed was /boot (only). The
other three drives make up /dev/md0.

The /boot drive was not backed up (headsmack!).

I have created a rescue USB stick based on the System Rescue CD, which
boots via grub. I can boot the System Rescue CD successfully, and it
sees /dev/md0, which I can then mount and read from and write to.

I have attempted to create a kernel and initrd image to add to the USB
stick that will boot the box as if the kernel and initrd image were on
the failed (and now removed) boot drive.

I built the kernel and initrd image on a box similar to the box with the
failed hard drive. I replaced /etc/modprobe.conf with the file from the
target server, and then did 'yum install kernel-largesmp'. I copied all
the resulting kernel-related files from /boot to the USB stick, as well
as the appropriate directory from /lib/modules.

I then restored the helper box to its original state.

I booted the System Rescue CD on the target system and copied the
/lib/modules directory into place on /dev/md0. I fixed up grub/menu.lst
to have a stanza to boot the newly created SL4 kernel. I rebooted the
box, and everything seemed to be going swimmingly, until . . .

. . . the booted kernel seems unable to build /dev/md0 and the boot
process fails.

In the original configuration, the boot drive was /dev/sda, and the
drives making up the soft RAID partition were /dev/sdb, dev/sdc, and
/dev/sdd.

The System Rescue CD detects the USB stick as /dev/sda and the three SAS
drives as sdb, sdc, and sdd. All is well.

It's not clear to me what is going awry with the SL kernel, but as
the boot verbiage scrolls by, I see /dev/sdc referenced twice, and no
reference to /dev/sdd. When the kernel attempts to assemble /dev/md0, it
uses /dev/sda, /dev/sdb, and /dev/sdc and this fails and /dev/md0 cannot
be mounted and the kernel panics.

Help, please. Suggestions? Thanks.

BTW, I've put both SL4.8 Disc One, and the SL4.8 Live CD on a bootable
USB stick; both boot successfully, but I was unable to find a way to
make either one recognize /dev/md0, much less rescue me.

Cheers,
 Pann
  
If all you lost was /boot, you can probably boot off the install media 
in rescue mode so it mounts things, chroot to /mnt/sysimage/, then 
reinstall the kernel and grub packages as appropriate, make sure grub is 
installed to the MBR or whatever means you use to boot, and reboot.

Re: User interfaces for mysql

[Mark Stodola]

Larry,

Could you elaborate on this.  I'm having trouble following what exactly 
you are trying to accomplish.  If you want to provide a web interface to 
a mysql database using php, this is certainly possible.  You'll need 
apache, php, php-mysql all installed and functioning.  If you've written 
your php properly and have apache set correctly, the php will be 
interpreted and executed by apache when the clients visit, with your 
script outputting html back to the client.


I lose you when you say it will not execute, and then talk about the 
browser interface.  Have you checked apache's error logs? Are you trying 
to get the php to run on each client?  If so, then a web browser is not 
the way to go, unless you write a java applet to handle this, which will 
end up sandboxed.


Cheers,
Mark

Alien is a last ditch effort at best.  Are you able to obtain the source 
code to the .deb package and compile it yourself?  Odds are you are 
going to run into dependency/library problems with the debian package 
anyway, even if you do get alien up and running.


You extract the contents of the .deb using the following:
ar vx filename.deb
tar xvfz data.tar.gz
or
ar p filename.deb data.tar.gz | tar xz

You can then install it by hand or roll it into an RPM.

Re: Another side effect that crept in with SL 5.5

[Mark Stodola]

Larry,

Although my problem might be different, it may be relevant.  I've not 
used 5.5 (still hanging on 5.2).  I've run into problems like this as 
well with printing in a similar fashion.  I've found that the community 
adopted the use of texttopaps, which is horribly bugging, borderline 
CRAP.  Try editing /etc/cups/mime.convs and changing the text/plain 
filter back to texttops (remove the 'pa' from the existing entry).  My 
experience wasn't a non-printing, but a printing of something entirely 
different from what I expected (font, pitch, etc).


Another workaround may be to use enscript to generate a postscript or 
pdf and then send it to the printer.

Example:

enscript -q -B -MLetter -fLetterGothicLineMonospace7/11 
--margins=45::10: -o - filename.txt | ps2pdf - filename.pdf


Or a texttops filter:
/usr/lib/cups/filter/texttops pdf-gen postgres filename 1 cpi=16 
lpi=6 page-top=18 page-left=46 filename | ps2pdf - filename.pdf


Hope that helps.

Cheers,
Mark

This is almost as old as unix itself.
LPD  LPR
lpr does not recognize the -o cpi=10.   In fact it doesn't recognize -o 
cpi=12 or any other font size.
This script takes the complete parts (thousands of parts) list and inventory 
and allows users to input a partnumber, or range of pn's and print  labels 
from anywhere in parts list, awks the parts list and prints the labels at 
selected locations on a page of sticky labels.  Completely formated to label 
page.

Tests:
Removed the -o cpi=10 from script and it runs fine except the font size is the 
default of 12.
The output data was redirected to file junk 
If you cat junk | lpr -o other options -P ep900c it will print.

Add -o cpi=10 and it halts no error message - nothing.
Page is in CUPS as a sent file but no printing.
The hardware, printserver, printer is unchanged but with the upgrade to SL 5.5 
we can no longer print at a defined cpi.

To test we tried several printers on the network and all have the same result.
They work fine with out the -o cpi=10.
The job shows it was processed by cups but never is deleted from jobs list.

It like the font list was some how disconnected, lpr never times out after 
hours of letting it run.


It has got be something that was changed or upgraded and defaults set or ???

Re: Nvidia woes...

Sergio,

I haven't noticed any memory leaks, but I also haven't been actively 
hunting them down.  There don't seem to be any signs of dwindling 
performance before this happens.  Most times, it is just idling 
overnight.  At most, there is a small amount of network traffic on an 
isolated LAN of no more than 5 or so devices, mostly Win XP or SL5.2 
systems (often running off a custom livecd based on Urs' scripts).


What card/config/drivers are you running?

Hey everyone,

I currently have deployed a number of SL 5.2 i386 machines.  Due to the 
circumstances, I'm not in a position to upgrade them to the latest 5.x with 
ease.  Lately I've been having trouble with systems locking up hard that are 
running an nvidia card using the 190.42 or 195.36.15 proprietary drivers.  Dual 
monitors connected via DVI, twinview.

I've tried a GeForce 9600GT as well as a Quadro NVS 290 with varying success.  
The Quadro seems to have lasted about a month before locking, while the 9600GT 
is much more often, daily/weekly.  I'm running the stock 5.2 kernel 
(2.6.18-92.1.6.el5) and Xorg (xorg-x11-server 1.1.1-48.41.el5_2.1).  The 
systems are generally idle when it happens.  I'm having no luck capturing log 
data or kdump data.

The strange part is, having identical hardware in several locations, only some 
experience the issue.

Hardware:
Intel DG43NB motherboards (bios revision doesn't seem to matter at this point, 
running 98,99,104, or 105)
^- hardware revision is the same for all of them: AAE34877-402
Areca ARC-1200 SATA RAID card (latest firmware, 1.48), running 2 320G seagates
Additional PCI-e NIC, Intel PRO/1000, running e1000e v0.4.1.12-NAPI
Single stick, 1GB DDR2 (800) memory
PS/2 Keyboard/mouse

I'm curious if anyone else has run into similar problems such as this, and if they have 
found a solution.  I'm looking at trying the 185.18.31 drivers, which seem to be 
certified for linux by a few software vendors, according to nvidia's website.

What driver versions and/or card make/models are people using successfully?  
Any help or pointers are greatly appreciated.

As I said, not all of them are misbehaving, and I have several with the same 
config minus the video card running fine on SL5.2 and Windows XP Pro (SP3).

Getting desperate,
Mark

Re: Problem mounting cifs

[Mark Stodola]

You might be able to get some info out of the contents in 
/proc/fs/cifs/.  Does nautilus actually mount the filesystem somewhere, 
or is it using smbclient and friends to make it appear as such?  CIFS is 
actually quite different from SMB once you start digging into it.


Also, a newer samba might help.  I'd recommend checking out sernet-samba 
(http://enterprisesamba.org/index.php?id=54).
It's a build of newer samba versions against various enterprise linux 
distributions, including RHEL.  I had to upgrade a few of our servers so 
they could properly authenticate to a Win 2008 server.

Re: Clean SL 5.4 Install and Anaconda Disk Partitioning Madness

[Mark Stodola]

Brent L. Bates wrote:

 I've been searching Google for answers and can't find any, so I decided
to check here.

 I'm trying to do a clean install of SL 5.4.  I'm booting from an SL 5.4
x86_64 DVD.  When I get to the point of custom partitioning my drives,
Anaconda makes a mess of things.  I have 4 drives and I want 4 partions on
each drive.  The first partion will be `/boot', next `/', then `/data', and
finally a swap partion.  As I create each partition on each drive, Anaconda
will suddenly rearrange the order of the partions.  When I go onto another
drive, the order may be different than the last drive I just partitioned.
 When I try to do the 4th and last partition, I get an `Extended' 4th partion
(which is empty) and a real 5th partition, instead of a simple single
partition.

 In the end, what I want is the first partition on each drive combined
into a software RAID 1 and be `/boot'.  The next 2 sets will be software RAID
0's and `/'  `/data'.  The final partitions will be 4 separate swap
partitions that the OS will take care of.

 I've tried creating all the partitions on one drive and then moving onto
the next one and the next one, but it scrambles things up.  I've tried
creating the first partition on each drive, then combining them into the RAID
1 md0 device, and specifying the files system type, and mount point `/boot'.
 Next I go onto the next partition, which I've tried as a software RAID 0
partition and swap at various times.  This one usually works, but not always.
 When I get to the 3rd partition, then it will suddenly rearrange the
partitions on that drive.  I've even seen it suddenly create a swap partition
on a different drive than what I'm actually working on.

 I've done this with earlier versions of SL, but I don't remember having
this much trouble with Anaconda randomly rearranging things and creating an
extra unneeded partion.  Any insights would be greatly appreciated.  Thanks


I've noticed anaconda likes to try and be smarter than you.  Quite 
annoying.  You can probably solve this by specifying things explicitly 
in a kickstart file, pre-partitioning the disk using fdisk/sfdisk, or 
fiddling with the force primary partition check box and the order you 
specify the partitions in anaconda.  I've worked in the reverse order 
over the years, manually tricking anaconda, then forcing an sfdisk dump 
in, and finally resorted to tailoring a kickstart to do my bidding 
because disk sizes aren't constant for me.


Hope that helps a bit.

Mark

We have a process here were users must push files onto USB disks. The

In trying to do away with some complex, hacky scripts I'm trying to
udev-ise this. Ie. when a USB disk is plugged into the machine a symlink

serial number of the disk.

My udev rule is:
KERNEL==sd*, SUBSYSTEMS==scsi, SYMLINK+=disknumber-%E{serial}
It can create devices with symlink '/dev/disknumber-' but the
substitution of the ATRR{serial} bit seems to be impossible to get working.

The man page is usual includes no examples which might actually give me
the context I need to properly understand the 'printf-like substitution'
syntax that the developers are talking about.

Tim,

I think you are confusing sysfs with environment variables.  the %E{key} 
is used for environment variables.  The serial number is a SYSFS 
attribute.  Try changing %E{serial} to %s{serial} and see if it works.

Re: udev rule to name USB disks after their serial number

Tim,

I think you are confusing sysfs with environment variables.  the %E{key}
is used for environment variables.  The serial number is a SYSFS
attribute.  Try changing %E{serial} to %s{serial} and see if it works.

Cheers,
Mark




That didn't work unfortunately, my rules file now looks like this:
KERNEL==sd*, SUBSYSTEMS==scsi, SYMLINK+=disknumber-%s{serial}

Any other ideas?

It works here, I just made a /etc/udev/rules.d/10-test.rules file with 
your above line.
Next I ran 'udevcontrol reload_rules'.  I then connected my Kingston USB 
drive and /dev/disknumber-5B7A121E appeared.


Do you have any other custom rules that are mangling this one?

Cheers,
Mark

It might just be a peculiarity of the USB stick I'm using to test it
then since it's creating a device '/dev/disknumber-' looking like it
can't find the serial number.

 I'll try with one of the actual USB hard drives they're using when I
can get access to one next week.

Tim
  

You can verify that using 'systool'.  Try the following command:
systool -b usb -p -v
Find your USB drive in the output, and there should be something like this:
 Device = 1-2
 Device path = /sys/devices/pci:00/:00:1a.7/usb1/1-2
   bConfigurationValue = 1
   bDeviceClass= 00
   bDeviceProtocol = 00
   bDeviceSubClass = 00
   bMaxPacketSize0 = 64
   bMaxPower   = 200mA
   bNumConfigurations  = 1
   bNumInterfaces  =  1
   bcdDevice   = 0100
   bmAttributes= 80
   configuration   =
   devnum  = 3
   idProduct   = 1d00
   idVendor= 13fe
   manufacturer= Kingston
   maxchild= 0
   product = DataTraveler 2.0
   serial  = 5B7A121E
   speed   = 480
   uevent  = store method only
   version =  2.00


If no serial exists for the device, the serial = line will be absent.

Cheers,
Mark

Re: SL5.4 and Asus eee S101 netbook

I've installed SL5.4 on an ASUS eee S101 netbook that my lab has purchased.  Reviews say Fedora 10 and Ubuntu 9.10 work flawlessly (Ubuntu). 
http://www.newegg.com/Product/Product.aspx?Item=N82E16834220595


I usually use SL, so I've installed 5.4.   lscpi indicates that the ethernet controler is 
Atheros (AR8121 ...) and wireless is atheros (AR928X).  There are no atheros 
entries in the other card adaptor lists in the network configuration submenus.  So,  
neither the ethernet card nor wireless adaptors are recognized?

The README file from downloading atheros driver from madwifi shows  latest download is 
2/08.   README says lspci should show it as unknown and a 0x168x vendor ID.   
lspci -v indicates both ethernet  (8324) and wireless (1a3b:1067) are unknown devices.  
I'm guessing madwifi is not going to not work.  Looks like I need special software.

For lab usage, I don't need networking.  It would be nice to update software 
etc.  I'd install ubuntu if it gave me networking capability and which is not 
available via current RHEL5 SL distro.

thoughts?

This may be of help for the wireless (ath9k).

My guess is some more googling could shed light on the wired interface 
as well.

Hello to everyone,
I have a Scientific Linux CERN 4 installation and I need to control an
usb device with it.
My device is an Opal Kelly FPGA with an usb interface.
I need to access it from some c++ code.
In the FPGA user manual they say:
__
The Linux installation requires the addition of one file to the directory:

  60-opalkelly.rules -  /etc/udev/rules.d/

This file includes a generic udev rule to set the permissions on all
attached Opal Kelly USB devices to allow user access.  Once this file is
in place, you will need to reload the rules by either rebooting or using
the following command:

  /sbin/udevcontrol reload_rules
__
I successfully copied the file into rules.d/ but I still have some
problem.
I don't have the /sbin/udevcontrol application:
all the application with udev in their  name are:
udevinfo
udevtest
start_udev
udev
udevd
udevstart
udevstart.static
udev.static
udev_colume_id

the file 60-opalkelly.rules is pasted at the and of this mail.
How do I make the system load this rule manually?
If I reboot while the device is connected everything works fine,
except that I can only access the FPGA with root priviledges. Any way
to allow users to use it?
Thank you in advance,
Nicola Maggi


# udev rules file for all Opal Kelly VID matches.
# This file allows udev to change the mode to 666 (all read/write)
# for any Opal Kelly VID.
#

# For FedoraCore 5 and similar:
SUBSYSTEM==usb_device, SYSFS{idVendor}==151f, MODE=0666

# For FedoraCore 7 and similar:
SUBSYSTEM==usb, ATTRS{idVendor}==151f, MODE=0666

  

Nicola,

Those rules look like they were written for a different version of udev than
what SL 4 provides.
In order to reload new rules in SL 4, simply executing 'udevstart' should do
the trick.  It will cause a reload.
As for the rules, you'll need to rewrite them, which isn't difficult.
Newer udev (like the one in SL 5) have changed to allow everything in 1
definition similar to what you have provided.
The MODE entry isn't supported, you'll need an entry in
/etc/udev/permissions.d/ to handle that.
It will help if you know the device node name when writing the rules, or to
define one that will be consistent.

For example, here is what I use to make sure a serial adapter is always
detected correctly with the permissions I want:
# /etc/udev/rules.d/11-edgeport.rules
BUS=usb SYSFS{idVendor}=1608 SYSFS{idProduct}=0201 SYSFS{serial}=*-0
NAME=%k SYMLINK=ttyEDGE0%e
BUS=usb SYSFS{idVendor}=1608 SYSFS{idProduct}=0201 SYSFS{serial}=*-1
NAME=%k SYMLINK=ttyEDGE1%e

This generates /dev/ttyEDGE0, /dev/ttyEDGE01, /dev/ttyEDGE1, /dev/ttyEDGE11
aliased to the correct /dev/ttyUSB#.

# /etc/udev/permissions.d/10-udev.permissions
ttyS*:root:uucp:0666
ttyUSB*:root:uucp:0666

This gives any device node of /dev/ttyS# or /dev/tty/USB# permissions of
0666.

I hope that helps.

Cheers,
Mark

Hi,
thanks for the useful help but I just managed to find some time to
work on this problem.

I modified my 60-opalkelly.rules as follows:

# udev rules file for all Opal Kelly VID matches.
# This file allows udev to change the mode to 666 (all read/write)
# for any Opal Kelly VID.
#

# For FedoraCore 5 and similar:
SUBSYSTEM==usb_device, SYSFS{idVendor}==151f, NAME=%k, SYMLINK=usbFP%n

# For FedoraCore 7 and similar:
SUBSYSTEM==usb, ATTRS{idVendor}==151f,NAME=%k, SYMLINK=usbFP%n

and added this lines in the 50-udev.permissions file:
#opalkelly devices
usbFP*:nick2k3:nick2k3:0666

where nick2k3 is my non-root user.

I notice no change after a reboot or running /sbin/udevstart
Furthermore there is no usbFP device in /dev/ directory.
any hints?

(Anyway nothing I have done seems to prevent root access to the device
- which I think is a lucky thing-)

Thank you in advance,
Nicola
  

Nicola,

Try changing SUBSYSTEM=usb_device to BUS=usb.  I don't recall 
SUBSYSTEM being supported in SL4.
You can also debug your rules using udevinfo and udevtest.  lsusb might 
help as well, to verify vendor ID and such.


Cheers,
Mark

Re: dual head with ATI Radeon 43xx

[Mark Stodola]

I run a 3650 on SL5.2 just fine.  I don't see any reason why a higher 
end card on a slightly newer revision wouldn't work, except maybe kernel 
changes.  Just download/compile/install (I'm using 
ati-driver-installer-8-12-x86.x86_64.run) the ATI driver and you can use 
aticonfig to ease the Xorg editing.


I use the following to set up dual 19 LCD monitors, primary on the left:
aticonfig --initial=dual-head --xinerama=on --screen-layout=right \
--resolution=0,1280x1024 --resolution=1,1280x1024

On the kernel line, in your /etc/grub.conf file, append the string
nosmp (without the quotes).

I'm sure that will do what you want.

Alan

SL 4 used separate UP and SMP kernels, unlike the unified SL 5.
Your grub.conf should have 2 entries in there, just comment out the 
ELsmp entry, reorder so it isn't first, or change the default variable.

Try the CentOS package.  It will let you know of dependencies when you
