[ilugd] Linux boot from SAN disks to Internal disk

[Yashpal Nagar]

Folks,

I need some help, We have a Linux host which is currently running/booting
from a disk which is allocated from a SAN. We have to move bootable disk
from SAN to internal disks. We have used dd and created a copy of the SAN
disk to Internal disks. However, when we boot it says:
rootvg not found.

We have used clonezilla but it did't give work as expected.

I think there should be way around, can someone provide some hint or way
around this?

Regards,
Yash

[Yashpal Nagar]

Dear All,
I would like to have some discussion on Chef, how many people on the list
use it or aware of using it for day to day automation, provisioning and
compliance purposes in their Infrastructures. Also if there are trainers
who have good understanding on the subject and could deliver the training
on Chef for Corporate, please let me know offline.

Thank you

A very sad day indeed. I can't believe...it.

Raj has always been helpful to all the people of different age group.

I learned a lot from him during my early days by merely knowing him in
couple of ILUGD meetings.

You would be missed badly Raj

Re: [ilugd] sudoers - how do we manage it?

Thanks Karan, Satya

I'm exploring them but seems I can make use of these API, but there is
nothing already in place which is some sort of wrapper on top of
visudo/sudo with some features on top of it.

[ilugd] sudoers - how do we manage it?

[Yashpal Nagar]

Hi All,

I'm looking for a Open Source tool which can only manage /etc/sudoers. Now
before many start advising vi and many other such editors. We have no
problem in using it but our requirement is very specific - the size of
sudoers access file is very large and infact getting large day by day to
push on few thousand hosts.

It would be great to have few features like:

01. It provides a convenience to add new users, hosts, commands which user
is allowed to.. etc in a consistent manner. We wish to get this file
organized in the sense of free from human typos, abbreviations, standards
etc.

02. Many times the access is provided on temporary basis, and humans are
prone to forgetfulness. if there is some access could be provided for a
definite time basis, after which the access is automatically revoked

03. We are looking for a cursor based tool/utility which could possibly
mange it it in more affective manner.

if, there are commercial products as well, pls do let me know.

Thanks & Regards

Hi Debendro,

By default all block devices are accepted in LVM. If you want LVM to watch
out  only for certain type of devices, you have to put an appropriate
filter.

e.g to exclude CDROM you may put

filter = [ "r|/dev/cdrom|" ]

Given your requirement, you may try

filter = [ "a/sda[1-9]$/" "a/emcpower.*/" "r/.*/" ]

And don't forget to run vgscan -vv after making changes to lvm.conf, also be
careful if running on production, keeping the backup of lvm.conf is must.

Cheers!

It is amusing to read the whole story of FOSS's ability and the potential it
have. The complete debian desktop within 10min over the network with only a
network port as requirement is panacea for the industry like 'call centres'
where bringing up the machine ASAP is always high on demand. I'm sure you

I know that sounds great to fine tune the Linux servers to such
limits. But I wonder where exactly this requirement can be felt on
gateways, application servers, database servers - perhaps only in
banking/financial domain to avert the internal/external security?

There are so many Linux servers which are directly facing towards
public network with specific ports open, do they necessarily use
selinux now a days?

I remember one time experience with selinux when it started filling up
log files, when one of the program tried to access /home which it
found unusual.

So many people shy away probably because it (selinux)  is not being
used in /everyday/ use as other programs are such as iptable, ipchains
etc may be.

Though the functions of spyware, selinux might sound same but their
contexts are different.

Selinux is developed into the Linux kernel space to help to have
tighter control on the all the processes e.g how  they can interact
with files, devices, sockets, ports etc within the system.  Which can
be implemented by system defined policies.

So more precisely selinux is developed to enhance the Linux system
security beyond the trival system access controls granted in the form
of file permissions, privileges etc

On the other hand a spyware is nothing but a software which is
presumably written outside kernel space and  meant to be used for
fishing the information, to move/copy the information from one place
to another. A spyware can exploit any software system/app and used
that as a tool to hack the system information. A spyware is not
necessarily to be used as a means of enhancing the system security of
a Windoz box like in the case of selinux.

Little disappointed with the URLs provided,  thought of looking for
more information. This is not the first and last news from M$ on
violation of the patents, but the important thing is the "Ruling" by
the court this time. Which has ordered M$ to ban selling the M$ word
in the USA. Which is quite remarkable ruling.

Apparently the same new is spreaded across all the major news and
leading technology news websites.
some of them are

http://www.usatoday.com/tech/news/2009-08-12-microsoft-lawsuit_N.htm

which clearly tell how exactly Microsux ( kudos to Raj for inventing
ludicrously innovative term) violated the patents.

I4i, which mainly makes software for drug and defense companies,
obtained the patent for a "customized XML" tool in 1998. XML is a
specialized alphabet that can capture any kind of computer file as a
regular text.

Microsoft started using XML as an alternative way to save Word files
in Word 2003 and made it the default format for all Office files in
Office 2007.

This made it easier for Microsoft and its partners to create programs
such as accounting software that generates reports in Word formats,
says Rob Helm, analyst at research firm Directions on Microsoft.

not GoI, but the babus inside the Govt departments and their decision making
panels - who haven't envisaged such vendor lock ins. So untill we see enough
FOSS aware people inside the GoI, I wouldn't be surprised to see such
caveats. Instead would urge to keep on striving for our software freedoms,
freedom of choice and making sure more and more people are aware of the same
because  there is huge "end user" base exists in our govt offices who only
thinks "computer means windowz".

The good news is there is a change going on in GoI at many levels, their
acknowledgement of FOSS in e-governance is one of the most accurate example
of same, the interesting thing would however would remain to see its
implementation.

I think Pawan has been reasonably polite to make you understand what he is
talking about. I don't think you are still in adolescence or immature to
understand the whole point. Nobody has challenged you not to use SMS in your
life, but the point is when you are teaching someone, one can atleast expect
the *teacher* , not to do the same mistakes at the same place,  for what he
is drumming to others.

I can't stress enough on the flexibility to listen completely, honesty to
acknowledge the mistakes we made in our life, when you say something you
really mean it. Have you ever wondered why God gave us 2 ears and one
mounth? Surprised? good, so that you can listen more and talk less! But I no
wonder i see so many blokes who speak more listen less, everyday.

I would leave you with one line which "Robert T. Kiyoski" used in one of his
famous book.

"In old world content was king, in new world context is king"

whose context I have changed a bit, he said this in the context of
"economy", but I guess it is applicable to our "understandings" as well.

As Karanbir already suggested, there are only few cases you need to play
around with source. The default apache you get with any of the Linux
distribution should already be compiled for module support, means you can
include other modules at run time and no need to recompile it again.

To check whether you have built in support, on a apache 2 box, I see (notice
the mod_so.c )

WEB01:~ # httpd2 -l
Compiled in modules:
  core.c
  worker.c
  http_core.c
  mod_so.c

Coming back to your "To integrate JBOSS with APACHE" , you need to download
appropriate mod_jk and provide a appropriate config to apache, which tells
apache what module to load, its name, its location, JkWorkersFile ,
JkLogFile, JkMount , JkLogLevel and plenty more to mention.

There is no suse jboss rpms,  AFAIK till SUSE 10. Why not some one use
binary JBOSS available to all, which has built in some of the good startup
documentation, scripts (like start,stop etc), I don't think you require
anything once you get a appropriate JBOSS binary bundle.

One need to un'tar the JBOSS binary and setup the neccessary JAVA_HOME,
ANT_HOME & JBOSS_HOME
Need to be careful of the java if the pre-installed one you require or
something else, rest deployment etc is quite trivial and there is plenty of
documentation around. If you intergrate JBOSS with Apache then you must need
to have a appropriate mod_jk (x86 32bit or x86_64/AMD64) there are two
binaries for each.

Fantastic to hear that the event went so well. There is huge potential in
young generation, who have  lots of ideas and more importantly willingness
to do something, but the problem is how do we integrate and give them a
direction. Such events definitely helps to students and should continue to
happen.

My favorite is this -

RX/TX no errors or packet dropped, on both AIX, NFS client side.

Included the async also into the /etc/fstab and manually umount and mount
the file system.

NFSCLIENT: /home/idpssupp/REPORTS /mnt/amosoutput nfs
nfsvers=3,hard,nointr,noac,async 0 0

Now, when i run mount it doesn't show async as the option mounted the file
system with

it only shows

(rw,nfsvers=3,hard,nointr,noac,addr=10.35.0.169)

Any idea, why async is missed?

All I want is to avoid stale file system condition from NFS clients.

Both (NFS server, NFS client) servers are 1000mbps duplex full.

hdparm on NFS client you mean? NFSclient server is 15k RPM disks (2 T)
storage, RAID 1 & RAID5 with two raid array controllers.

Removed the entry from /etc/mtab

and ran the
mount -o remount /mnt/amosoutput

I really doubt if the above works, it simply come to next prompt

I still see

NFSCLIENT:~ # ls -l /mnt/amosoutput
/bin/ls: /mnt/amosoutput: Stale NFS file handle

the entry for the /mnt/amosoutput didn't reappear in /etc/mtab after I ran
the mount with remount option. mount though shows the new options picked
with for the shares in question.

nointr -- I can try with, but why even after remount, it doesn't pick
options.

[ilugd] NFS client - Urgent

[Yashpal Nagar]

Hi All

We are running  NFS clients on Redhat and SUSE linux distros with the
following options.

NFSSERVER:/home/idpssupp/REPORTS/mnt/amosoutput nfs nfsvers=3,bg,intr 0
0

for some time quite happily, recently we have encountered the messages on
NFS clients

Apr  7 07:11:51 NFSCLIENT kernel: nfs: server NFSSERVER OK
Apr  7 07:11:51 NFSCLIENT kernel: nfs_statfs: statfs error = 116
Apr  7 07:21:06 NFSCLIENT kernel: nfs_statfs: statfs error = 116

I have tried using...
NFSSERVER:/home/idpssupp/REPORTS/mnt/amosoutput nfs
nfsvers=3,hard,intr,noac 0 0

and ran

mount -o remount /mnt/amosoutput

but still we get the following...

NFSCLIENT:~ # ls -l /mnt/amosoutput
/bin/ls: /mnt/amosoutput: Stale NFS file handle

The above problem appears intermittently and would disappear if i just
umount and mount the file systems manually.


A call is already raised with Redhat but still no response.

We have mix of NFS clients on RHEL ES 4, SLES 9 and NFS server is AIX 5.2
ML10. Any help is much appreciated.

By default known_hosts records the hostname/IP in hashed format. You can
turn it off by putting the follwing into .ssh/config

HashKnownHosts no

I was under impression that one must need to have hostname/IP in known_hosts
to use "ssh-keygen -R hostname/IP" , but I just tested it works! whether
your hostname/IP is there or not in known_hosts , you can user ssh-keygen -R
anyway...

Excellent, thanks for your help!

The file which sends the data to add into the .ssh/known_hosts on your local
server, from the target host is
  /etc/ssh/ssh_host_rsa_key.pub

The above URL states that known_hosts format support wild cards and you can
setup your file such that it wouldn't prompt you adding the keys everytime,
if your target host is on a DHCP.

Precisely something like this I was looking for, which is a clean way of
doing this.

But .ssh/known_hosts doesn't record the keys with hostname/IPs, atleast with
OpenSSH_4.7 with Ubuntu. So this option is not helpful.

I understand older openssh-clients-3.6.1p2-18 such as on RHEL 3.0, records
keys along with IP/hostnames But there is no "-R" option with ssh-keygen!

So, I'm still trapped, to find more.

But still I need some more information, URL etc to know what happens when

[ilugd] .ssh/known_hosts

[Yashpal Nagar]

Hi all,

On one of a servers I recently build with SLES 10 SP2,  I didn't created any
ssh private and public key pair -- id_rsa and id_rsa.pub for root user
When i tried to ssh this server it gave me offending key warning on my local
server (/home/yash/.ssh/known_hosts)  because I had recently formatted the
target host, So the finger print/key is changed which is normal.

But the problem is when i tried to locate the public key in
/home/yash/.ssh/known_hosts I didn't find any key with a reference to my
target host/IP alongwith. All I found is a file, with full of keys and its
damn diffcult to find which I was looking for, Generally i look for target
hostname/IP, if either of them is matched, I just remove it and it works. Is
there any another way to find the matching key of the target host?

Now I have created the key pair public and private but still same result-
the file known_hosts still doesn't have any key with a host reference in it.


what I want to understand is, if one doesn't create a pair of keys then how
does the authentication takes place? If it is on the basis of server finger
prints then how/where these finger prints picked up and presented to ssh
client?

Server is running openssh-4.2p1-18.36, with a ssh client OpenSSH_4.7p1
Debian-8ubuntu1.2,

[ilugd] Recovering data from Linux LVM

[Yashpal Nagar]

Hi All
We have got a Ubuntu desktop used for some development, which is
crashed recently and not happy enough to boot. It has got the
following partition table.
   Device Boot  Start End  Blocks   Id  System
/dev/sdb1   *   1  31  248976   83  Linux
/dev/sdb2  32   30394   243890797+   5  Extended
/dev/sdb5  32134610562706   82  Linux swap / Solaris
/dev/sdb61347   30394   233328028+  8e  Linux LVM


I booted with Ubuntu-Live CD and couldn't recover anything. Finally
attached the disk(via USB port) as a secondary disk on a already
running Ubuntu desktop.
Disk detected (/dev/sdb) OK, and installed lvm2 on running Ubuntu.
After i run though vgscan i could also see VG and logical volume.

There is only LV with a single PV.

[EMAIL PROTECTED]:~# pvscan
  PV /dev/sdb6   VG Ubuntu   lvm2 [222.52 GB / 0free]
  Total: 1 [222.52 GB] / in use: 1 [222.52 GB] / in no VG: 0 [0   ]

I have got the following issues if somebody could help

1. How do I find the "file system type" on the defined LV, under the
Linux LVM partition? Mounting of LV always keep on saying you must
specify FS type, but it does't take anyone of ext2, ext3, reiserfs as
the file system type.
2. I have run though fsck.ext3, fsck.ext2, fsck.reiserfs but none of
them runs successfully
3. There are some bad blocks, can i mark them and still live with this
disk and if could recover some data?

Thanks and Regards

Thanks Arun, I got it sorted.

I forgot to disable "SATA Operation" opion to "Off" in BIOS. Since I
am not using Nvidia software raid, it is important to disable this
option. Interesting thing is by default this option is Off, but I
found it "On" on even another new Optilpex box.

After that everything worked OK.

[ilugd] nvidia Optiplex 740

[Yashpal Nagar]

Hi All

I am facing a problem with a Optiplex 740 from Dell to set it up for
with SUSE Linux 10 SP2.
No matter whatever way I installs it says..

NO BOOT DEVICE DETECTED, INSERT SYSTEM DISK AND PRESS F1 TO CONTINUE
OR PRESS F2 TO SYSTEM SETUP

There seems to be a nvidia software raid onboard, which I have
disabled as Linux installation advised not to use that.

Anyone could be of help?

Regards
Yash

 I got Nintendo Wii as a free gift with a mobile deal from

for £35/month contract.  But not sure how many DVDs etc are available

Is there any way to verify that pciid is locked and stay assured that

Since it has changed in our case, it is important to check that.

Yes, I  believe so, looked at the grub.conf it no where mentions any
name like c1d0 or c0d0.

Good suggestion, BTW is there any way we can control this naming, with
program such as udev?

I am bit concerned about, what happens if it flips and it expects root
at c0d0p1, in that case what should i do?

Thanks for your help

[ilugd] Raid controller naming

[Yashpal Nagar]

dears,

We have got a server with two array controllers P400 (built in card),
additional card P800 (PCI card), each connected with 8x146Gb SAS
drives.
which i am required to built for a new Sybase database and
application. Server is DL 585 G5

I installed RHEL 4.0, P400 appeared as /dev/cciss/c0d0 and P800 as
c1d0. All went nicely and installed GRUB on /dev/cciss/c0d0; It was
just warming up and again required me to re-install.

This time P400 appearing as c1d0 and P800 as c0d0 during installation.

Does anyone know what can cause this device name to swap, & how does
it effect server in case it happens again? I have allocated everything
under LVM2 except (/) file system,  / is at c1d0p1 now.

The only changed I can think of is:
a) opened the server to check Raid cache memory backup "battery" on
p400, whether present or not, No other change
b) made some changes into the BIOS relating to booting preference, NO
other change

Any guesses?

Yash

We use Nagios extensively to
1. Generate system and resource utilizations
2. Report our system/services uptime and SLAs
3. System hardware failures e.g disk etc
4. Report capacity planning and management

Bit curious about vmware monitoring though? but rest of the things
Nagios just works out of the box :)

Indeed very nicely drafted, and I also enjoyed Eric S. Raymond's
article on economics of FOSS.

On Eric's chapter 10, When To Open, and When To Be Closed.

How much the FOSS is effected in case M$ also open its source?

Secondly like this article, Is there any single place where all the
software's licenses are explained? No I don't want to become FOSS
advocate rather want to understand with simplicity like Eric explained
the complex subject of economics in FOSS.

[ilugd] Redhat update roll back

[Yashpal Nagar]

Hi there,

We recently upgrade a update from RHEL ES 4.0 U6 to RHEL ES 4.0 U7,
which has broken some functionality in one of our application. This
application which I am not very much familiar about, appears to
utilize Firefox libraries, and application support has told us Redhat
has removed some libraries which is the basis for the problem.

Now I am looking for a roll back, from update 7 to update 6. I have
already raise a call with Redhat and waiting their reply.

But I have full faith on list and just wondering if someone already
have some experience on such problem and could share some thought?

Regards
Yash

Yes, it is mission critical, as critical as if data is not available,
flight wouldn't take off.
But it is not on RAID0, as I said "experimented" for the example shake.

if I am not wrong the disk is already added into the array while the
system was online, the moment you add the disk, array expansion
started stating - expanding.

It the scsi kernel module which required to be reloaded.

single user mode -- to add the partition into LVM?

correct but, file system umount was required for ext3 on RHEL 4

True, But you can very well remove and add hot spare disks. You can
also remove even a single hot spare drive in a RAID5 array.

> removing 2 disks will fail the virtual drive with loss of data.

Correct.


I experimented a bit on this and found expanding a array carefully
does't lead to any data loss. Here is what experimented

Created a RAID0 (called array B) with single disk(146GB) with hpacucli.

Initialized the disk into LVM.
created a VG and a LV under LVM2 and put some data on the logical volume.

Now i went ahead and expanded the Array B with hpacucli, with another
disk(146GB) into RAID0, it took 15min/per GB to expand the array as HP
documentation states. After expanding finished, I saw both the disks
were appearing OK into the array B.

hpacucli slot=<0> array B add drives=

Now i needed to expand the logical drive

hpacucli slot=<> ld 2 modify size=max
#here I found logical drive expansion almost instant, however HP
document states its should be 15GB/min

Under Linux, after any logical drive expansion under RAID system, you
must need to reboot the server.

After reboot, run fdisk -l, I found the drive now expanded, showed me
293.6 GB instead of 146GB earlier, i needed to pvresize the physical
volume into the LVM and VG was automagically expaned.

Mounted the LV and found the data intact with no problem.

So in theory it appears like expanding the array with new disks works,
with no data loss and you require a reboot into Linux. My OS was RHEL
4.0 ES

[ilugd] HW raid question

[Yashpal Nagar]

Hi All

On a HP DL580 G4, intel 64bit with Smart Array P400 Raid controller
card with SAS disk drives.

Here is how i have installed SLES 9.0

tuxx02:~ # hpacucli ctrl all show config
Smart Array P400 in Slot 4(sn: PA5360J9STQ0QK)
   array A (SAS, Unused Space: 0 MB)
  logicaldrive 1 (136.7 GB, RAID 1+0, OK) ** contains OS**

  physicaldrive 2I:1:1 (port 2I:box 1:bay 1, SAS, 146 GB, OK)
  physicaldrive 2I:1:2 (port 2I:box 1:bay 2, SAS, 146 GB, OK)

   array B (SAS, Unused Space: 0 MB)
  logicaldrive 2 (546.8 GB, RAID 5, OK) ** contains Databases & apps **

  physicaldrive 1I:1:5 (port 1I:box 1:bay 5, SAS, 146 GB, OK)
  physicaldrive 1I:1:6 (port 1I:box 1:bay 6, SAS, 146 GB, OK)
  physicaldrive 1I:1:7 (port 1I:box 1:bay 7, SAS, 146 GB, OK)
  physicaldrive 2I:1:3 (port 2I:box 1:bay 3, SAS, 146 GB, OK)
  physicaldrive 2I:1:4 (port 2I:box 1:bay 4, SAS, 146 GB, OK)
  physicaldrive 1I:1:8 (port 1I:box 1:bay 8, SAS, 146 GB, OK, spare)

I need some extra storage, and thinking to remove the spare disk (1:8)
 from array B, and create "array C", and then initialize the disk into
the LVM2 and create LVs.

Is there any other way around? e.g without removing the disk from array B?

What I also want to understand is, does hardware RAID system really
care about data, what happens to the data if one, add a disk into the
existing logical drive?
e.g logicaldrive 2, what if I unkmark the disk as spare, what happens
to logical drive/date??

Thanks and Regards

No

This is exactly, where this thread started under what "basis" linux
time zone start showing only Calcutta as the only choice. Is there can
be other reason apart from,  British considered it as the capital
during their time?

I agree Vivek's point to checkout, how other countries with single
timezones handled this issue.

ServerXX:~ # free -m
 total   used   free sharedbuffers cached
Mem: 12008  11978 30  0216  11175
-/+ buffers/cache:587  11421
Swap:10236   4567   5668

It appears then Linux uses lot of memory as "cached" such as 1175 MB
in this case, which is nothing but free Memory reserved for other
process utilization. Is there any limits for cached/buffer part?

[ilugd] Linux Memory utilization

[Yashpal Nagar]

Hi All

Recently I came across a problem, few of our Linux servers utilise
almost whole of the 12 GB physical RAM on servers hosting Sybase
databases. No matter whether the Sybase database utilization remains
at peak or low and/or we have multiple instances of Sybase or not,
but Memory utilization appears to be constantly high.

What I wanted to know is a on a normal database servers Sybase or
Oracle, what kind of memory utilization on Linux as the OS, is
considered safe/good, to perform its best? Our system is running on a
SUSE eneterprise Linux 9 SP3 x86_64.

I know there would be database level tunings also which makes lot of
the differences but assuming the database is tuned.

Regards
Yash

Very well said infact this is frustrating to see wrong maps at many
places including BBC, worldtimezone and many more.
But this is not right forum, to protest for this. If you come across
one, don't forget to tell, please!

Sure, using Linux for more than 8 years professionaly and almost lost
in too many of linux distributions Redhat, fedora, SUSE, Ubuntu,
Debian :)) The issue i have got it i don't want to know how other
distribution works differently, in this case Xandros (aahh..) instead
just want to use yum, apt etc for any Linux distribution so that i can
get it up & working what i need as a tool, whenever. You may call me
too lazy, but, this is what too many things to remember, to do/
achieve same thing in different ways.

I could use yum,apt with this as well, is, great news to me, i would
try & check how everything goes. Infact i was looking for this..

>

Will try this, after i could connect by this probably will switch to
this laptop. But does my company allow to use personal laptop ,
umm, but i can connect from home anyway ;)


Thanks for your help!

[ilugd] ASUS Eee PC 900

[Yashpal Nagar]

Just got hold of one, after waiting for about 2 weeks from PC world, 
thought of sharing some experiences with you.

System config

ASUS eee PC 900

RAM 1GB

Disk 20 GB SSD

processor 800Mhz celeron

Xandros Linux


First some of good noticeable features

   1. booting is very fast, by the time you plug the power, system is
  up, absolutely no wait time or gazing at cryptic boot messages

   2. IO is very fast; e,g copying from SD mem to disk or vice a versa
  , just took out SD card from my digicam & inserted, it immediately
  opened photo manager

   3. hybernating works perfectly, just click & done, for waking upjust
  press any key, instantly you would see OS ready

   4. Skype with video works perfectly

   5. Set of applications provided are mozilla firefox, mozilla
  thunderbird email client, Open office 2.0, acrobat reader, pidgin
  2.0, dictionary, printing system/drivers, voice command – well you
  can call certain commands by voice e.g “computer movie” to play
  built in movie player etc 

   6. Speaker, mike works good with reasonable pitch

   7. Wirelss detects nearby clouds good but still need to test

   8. less weight, very handy & somewhat attractive

Flip sides

   1. keyboard size is very small, one would require practice but should
  be manageable after some time

   2. Its a good laptop on the move with any flavour of linux, so far
  tried, Ubuntu though, but I think not suitable for serious office
  work.

   3. You would not find any command line terminal, no xterm

   4. display max at 1024x600

   5. Memory 1GB , SSD disk 20GB is OK, but some more justice should
  have been done with processor which sometimes appear as busy

Finally i have decided to put Ubuntu as the main OS on it and will live 
with it any way at home ;)

Yash

How much did it cost in India? did you check if Eee PC 900 is also
available there? share some info about how did you make USB stick
bootable; people install ubtuntu even on SD cards.

later have 20GB and its hard to get hold of one in UK.

[ilugd] Hardware faults with Nagios

[Yashpal Nagar]

Folks

How do we use Nagios, for detecting hardware faults, like hard disk
failure, RAID controller failure/error, Network card down etc. Is
there any plugins around for same. We have Nagios using for system
health and service monitoring All doing well, with NRPE plugins but
lacking hardware faults detection and reporting.

Indeed a great news! Congratulations to the team who voted against Open 
XML, it proved that few headliner companies like TCS, Wipro, Infosys etc 
can NO way define the Indian standards.

Thanks a ton Raj, Niyam for share this.

Asus Eee PC 900 seems to be a great deal if you really serious about
Linux as the OS & value for money.

 I have no idea when it would hit in Indian market, but appears to be
promising, comes with 20GB (Solid State Disk, read more about SSD ),
Intel processor, 1GB RAM preloaded with Linux.

http://www.reghardware.co.uk/2008/04/16/asus_launches_eee_900/

Hardware specs goes here

http://blogs.guardian.co.uk/technology/2008/04/15/asus_releases_eee_pc900_specifications_and_uk_prices.html

People in a couple of linux mailing list are desperate to get a copy of it!

[ilugd] Microsoft must pay $1.4bn to EU

[Yashpal Nagar]

The European Commission has fined US computer giant Microsoft for

[ilugd] smbclient & Traffic

[Yashpal Nagar]

Hi

I am running a NFS server (AIX 5.2 ) to export some file system having
certain reports to a Linux server (SUSE 9.3).  At present both of
these systems are on two different LANs but speed is not the issues
and so far working fine. Now we are putting this AIX  server to a
geographical distant place and it would require to supply same
reports.  I belive, to run NFS over the WAN would be too much of
traffic. Samba server is already running on AIX and neccessary
firewall rules are also placed in WAN to access shares etc.

What i am looking at is, can i use smbclient to mount these file
systems instead of NFS, having said i already have samba server and
firewall rules in place. What kind of traffic smbclient generates in
comparison to NFS,  is it reliable? or there any other program
available.

Regards
Yash

[ilugd] Microsoft set to open up software

[Yashpal Nagar]

Microsoft has announced that it will open up the technology of some of
its leading software to make it easier to operate with rivals'
products.
The technology giant is to publish key software blueprints on its website.

It also promised not to sue open source developers for making that
software available for non-commercial use.

Microsoft is being investigated by the European Commission on the
grounds that limiting access to its technology could be stopping
competition.

[ilugd] FOSS to drive Kerala's first e-governance Web GIS

[Yashpal Nagar]

Kerala's e-governance initiatives have decisively turned its back to
Proprietary software systems like Microsoft. This was evident when the
State's first active web GIS (Geographical Information System) was
launched in public domain this week.

It was using Free and Open Source Software (FOSS) technology that GIS
was developed, KR Srivathsan, director, IIIM-K (Indian Institute of
Information Technology and Management- Kerala) said.

"The main objective of Active Web GIS is to make the dynamic
geographical information available in a simplified, open Web
interface," he added.

Knowledge of spatial data is becoming increasignly important for
scientific and business organisations to make informed
decisions."Active Web GIS is very crucial when the location-specific
information is dynamic and decisions have to be made on real time
basis," Srivatsan said.

Absolutely, by definition of dual core, it is ok to increase the count 
of CPUs into the operating system, as "operating system perceives each 
of its execution cores as a discrete logical processor with all the 
associated execution resources"
So depending upon the no of cores, you may see same number of logical 
processor, fine.

But in case of HT which is a technique, to create different set of 
instructions for the same CPU, so that it can better utilise CPU 
resources. Essentially it also does't have two CPU execution resources 
as in the case of "dual core".  Then why it is so important to show them 
as two CPUs in the OS? Is HT technology also means to increase the cpu 
logical counts and thus increase the performance for CPU intensive apps?

Yes, it is dual core. The presence of the ht flag in /proc/cpuinfo 
merely indicates that the processor reports its Hyperthreading 
configuration, even if it is disabled or not supported.

is there any way to disable dual core?

[ilugd] Intel HT

[Yashpal Nagar]

Hi All

On a HP blade BL460 G1 server where there is no option to disable the 
hyper threading in BIOS. The only options it has is -

Advance -> processor Options ->
 \--> HW prefether
 \-->Adjacent Sector Prefetch
 \--> No-Execute Memory 
Protection
 \--> Inter (R) 
Virtualization Technology

BIOS version is I15 05/01/07, Called HP who told to upgrade Firmware but 
appeared to be unsure whether upgrading would really fix. Current 
firmware version also is not very old.
There is a application hosted on these boxes which requires the 
hyperthreading to be turned off.

I tried to disable HT by putting the "noht" keyword in the kernel 
argument line in grub.conf
## grub.conf
...
title Red Hat Enterprise Linux ES (2.6.9-42.ELsmp)
   root (hd0,0)
   kernel /vmlinuz-2.6.9-42.ELsmp ro root=LABEL=/ noht rhgb quiet
   initrd /initrd-2.6.9-42.ELsmp.img
...
##

but it did't work,  Blades have 2 Xeon 2.33 Ghz processors, appearing as 
4 in the OS,  /proc/cpuifo clearly tells processor is definitely HT 
capable.

flags   : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge 
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall 
lm pni monitor ds_cpl est tm2 cx16 xtpr
cpu cores   : 2

is there any other way around?

Yash

re-installation is required for the following two purposes.
1. rpm re-installation of glibc-2.3.3 will overwrite the original files 
once again and will ensure, you have all the files at right path, 
permissions, md5 etc are ok
2. re-installation will also help to re-establish the symblinks.

What I did is, established a sftp connection from the error free server 
to the faulted server just incase something breaks and it require to 
copy some libs again, and re-installed the glibc-2.3.3  with --force 
option on it.  Then I also required to copy the following files with sftp
ld-linux-x86-64.so.2
ld-lsb-x86-64.so.2
ld-lsb-x86-64.so.3

which are nothing but symblinks to the same file ld-2.3.3.so. It worked 
with only downside is rpm database still have a inconsistence 
glibc-2.6.1 installation, which i am ok to bear that ;)

Thanks a lot guys for your help!

I boot the system with Ubuntu x86_64, Live CD, and mounted the root file 
system (/dev/cciss/c0d0p4) and found ld-linux-x86-64.so.2 was already 
present.
# ls /mnt1/lib64/ld-*
ld-2.3.3.so
ld-linux-x86-64.so.2
ld-lsb-x86-64.so.1

Then i just copied all the /lib/* and /lib64/* from another system, Then 
i rebooted and found the above error
# boot errors###
blogd: no message logging because /var file system is not accessible
Boot logging started on /dev/tty1(/dev/console) at Thu Nov 29 13:36:25 2007
Master Resource Control: previous runlevel: N, switching to runlevel:3
Master Resource Control: runlevel 3 has beenreached
blogd: no message logging because /var file system is not accessible
###

As we had to power down the system (we could't issue any shutdown 
commands), i thought it might be beacuse FS might have a problem and 
require manual fsck'ing. Again booted the system with Ubuntu Live CD and 
run fsck.ext3, e2fsck on all slices, checked the *free file system size, 
which was ok, and then again try to boot the system. But no luck same 
error as above given.

This time booted the system with SLES 9.0 SP3  and run rescue,  and run 
fsck.ext3/e2fsck once again on all slices inlcuding /var 
(/dev/cciss/c0d0p6), but same error, this time i also verified 
/etc/fstab also which appeared to be Ok. Then i move ahead and try to 
use the "Repair Installed System" option available in the SLES. All the 
system verification tests passed except that, some of the package could 
not verified, i tried to repair them (which cause them to re-install), 
but installation of many of the programs failed!

By this time i had a very little hope, time was running away, as this is 
a key production training system. I started moving the application 
installation data (installed under (/) FS) to another slices 
(/dev/cciss/c0d1). Fortunately i had, two big slices (/dev/cciss/c0d1p1 
/ /dev/cciss/c0d1p2) RAID5, where I moved, most of the data from 
/dev/cciss/c0d0/p*.  I thought not to format any OS slices ( / , /var, 
/usr) and just re-install SLES 9. But all goes fine except during the 
RPMs installation the same RPMs (which failed during Repair option) got 
failed again, to install.  Since i had already taken backup,  i 
re-installed the SLES, with format option :(

The issue is I still have two boxes with glibc-2.3.3 and glibc-2.6.1 
installed

host3:/ # rpm -qa|grep -i glib
glibc-i18ndata-2.3.3-98.61
glibc-32bit-9-200512100800
glibc-locale-32bit-9-200512100801
glibc-2.6.1-18
glibc-locale-2.3.3-98.61
glib-32bit-9-200501041713
glibc-info-2.3.3-98.61
glibc-devel-2.3.3-98.61
glibc-devel-32bit-9-200512100801
glib-1.2.10-586.2
glibc-2.3.3-98.61
glib2-2.2.3-117.2
glib2-32bit-9-200507121454
glibc-2.4-31.2

Could anyone help, to properly remove glibc-2.6.1 ?

Thanks a lot for your patience :)

Best regards,
Yash

[ilugd] glibc2.6.1 problem - Urgent!

[Yashpal Nagar]

Hi All

One of my mate upgraded glibc from glibc-2.3.3 to glibc-2.6.1-18 on a 
production server SLES 9 SP3 withou thinking any consequences. This also 
required to install openssl-devel-0.9.8a-18.4 & openssl-0.9.8a-18.4 as 
one of the dependencies for glibc-2.6.-18, while compling NRPE pluging.

Now i have removed the glibc-2.6, openssl-devel-0.9.8a-18.4 , 
openssl-0.9.8a-18.4 after looking glibc2.3.3 is still there. Which has 
invited other problems like-

TUWIGMAMS02:/bin # ls
-bash: /bin/ls: No such file or directory
TUWIGMAMS02:/bin # cp
-bash: /bin/cp: No such file or directory
TUWIGMAMS02:/bin # rpm -qa
-bash: /bin/rpm: No such file or directory
TUWIGMAMS02:/bin # cd ..

Could anyone please provide help, what are the options i do have now!

Best Regards
Yash

Apart from uptime, which tells about the load average in the form of 
average number of processes essentially in "run_queue" at a time, over 
last 1 minute, 5 minute and 15 minutes. There is another program called 
System Acitivty Report (SAR) which represents the CPU utilization in the 
form of percentages.

The CPU load monitored by SAR is shown in %

[EMAIL PROTECTED]:/var/log/sa> sar -f sa31|more
Linux 2.6.16.21-0.8-default (hostux2)   31/08/07

00:00:26CPU %user %nice   %system   %iowait
%steal %idle
00:01:26all  0.98  0.00  0.53  0.78  
0.00 97.70
00:02:26all  0.80  0.00  0.33  0.65  
0.00 98.22

How does this % relates to the uptime output? Does this % refers to the 
run_queue capacity? Is there any way we can modify run_queue.

In SAR's case, is it fair to sum the % of queues (excluding %idle) and 
conclude that as the total "CPU load" at that time?

Yash

Very interesting to know the difference between "cpu utilization" and 
"load".

Do you also know where are the Dr. Gunther's Quiz answers?

[ilugd] Uptime

[Yashpal Nagar]

Hi All,

>From the man pages of uptime, you get

Print the current time, the length of time the system has been up,
the number of users on the system, and the average number of jobs
in the run queue over the last 1, 5 and 15 minutes.

But when actually you run uptime, you get load average instead
[EMAIL PROTECTED]:/var/log/sa> uptime
 12:36pm  up 223 days  3:05,  1 user,  load average: 0.00, 0.00, 0.00

How does the jobs in the queue and load average relates to each other. could
anybody help me to understand ?

Re: [ilugd] Online activity declining in linux-delhi/linux-india

[Yashpal Nagar]

I secondly agree to Kenneth, the environment in the list is not conducive.

People's attitude about small-2 questions being asked, HOWTOs, questions
about other linux distributions like SLES or RHEL are poorly treated to such
a level that, person, might not ask any question again after that... :(

lately i found even some person even strangely asked "How, Microsoft abused
its dominant position.." is related to linux ?


I am sure, there are more than dozens people in the list, who mostly replies
like ask Novell, ask Redhat, read the RTFM etc, instead of, if they don't
want to participate, if the topic not of much of their interest, just ignore
that.. don't provide such comments which could embarrass the sender.

What about people using devices such as digital camcorders or digital
cameras with linux? I am sure you can't discuss such things in ILUGD! There
are other GNU/Linux lists in the world where people do't hesitate to discuss
anything about GNU/Linux, no matter whatever directly or indireclty it is
related to GNU/Linux or FOSS.


I believe what we can discuss, what we can't, is this list only for Linux
OS, that too only like Debian? need to be properly defined at the ILUGD
website and if possible define a one liner in the bottom of every message.

Secondly we need to be more flexible in accepting emails of whatever type
relating to Open Source, GNU/LINUX, etc and remove the obligations such as
tagging the subject of the messages to [OT], [commercial], refrain sending
warnings to the OP.


Being a member of ILUGD fior more than 8 years, i know few of the people out
there and i keep on, i don't mind. But what about the newbies? :)

I believe yes, the online participation is decreasing, we need to be more
open and flexible to discuss a revolution in software such as Open Source or
GNU/Linux.

Yash

[ilugd] Slow tar

[Yashpal Nagar]

Hi All

On a production Linux box with tar (GNU tar) 1.15.1, i want to nightly
backup most of the file system & then scping/rsync to another box. How do we
use tar with limited resources like some specific cycle of CPU to use
e.g20% CPU, with specified I/O or bandwidth limit
e.g 50MB/s

if anybody could point something would be a great help.

Re: [ilugd] Microsoft loses anti-trust appeal

[Yashpal Nagar]

 Microsoft to carry out EU ruling:



The European Commission said Microsoft will now charge a one-time fee of
10,000 euros to firms that want "complete and accurate" technical
information on Windows software.

In addition, it will also allow the data to go to open source software
developers.

Open source software allows users to read, alter and improve its code - in
contrast to proprietary software where a company controls the source code.

Re: [ilugd] Network card firmware

[Yashpal Nagar]

Hi Asish,

I have tried lspci , ethtool, lshw  but i don't think anyone of them
provides firmware level detail for network card.

HP provides some CLI based utilities like hpacucli, which can provide such
details for RAID array controller, but there is no utility for network card.
Can anyone help?
