Or you could use http://rg3.github.com/youtube-dl/ which is part of the Fedora

youtube-dl 'http://www.youtube.com/watch?v=nAQpU5sg-P4' will nicely grab the

But the less than 80 character wide limitation isn't a limitation set by our 
body it was a limitation set by the older displays.

People in most places tend to read horizontally rather than vertically 
therefore I don't see why hardware shouldn't accommodate that and allow me to 
read horizontally more than vertically.

Personally I also like to take printout of reports in landscape mode ..

I am not sure what is the big deal with widescreen monitors and coders :) - I 
do coding for a living and I use widescreen monitors both at work and home. I 
actually use 2-3 4:3 monitors at work depending upon how wide I need it to be.

Among other things try doing a diff across three files on a widescreen monitor 
and see how useful all that space is. Next I don't have to worry about my code 
getting wrapped just because my display doesn't go that far wide. It is also 
useful for people who are working with datasets - most computer generated 
datasets wont care how wide your display is - I have seen 256 columns or more 
of dataset flowing into some of the apps I work with. With a wide screen I can 
keep my email, browser and terminal all open without having to switch between 
them - try debugging a web based service while looking at the server logs.

> Even for those who use computers for common office applications, the

MS Office reading pane nicely splits into multipage format irrespective of your 
screen dimension - it is always nicer to be able to read larger text than 
everything squeezed into a 4:3 monitor.

End of the day I think we have to adapt ourselves to the hardware than expect 
them to modify to our style. Do remember there are more people buying 
widescreen HDTV than people buying consumer grade LCD monitors so the incentive 
is to go widescreen especially since you can claim a larger size for lesser 
pixels if you manufacture 16:9.

Re: [ilugd] ntp sync to server bt still drift is there

[Mithun Bhattacharya]

I don't know which distribution you are using but on Fedora I do the following:
1. Setup decent NTP servers in ntp.conf - I set the following
server 0.fedora.pool.ntp.org
server 1.fedora.pool.ntp.org
server 2.fedora.pool.ntp.org

2. Run ntpdate at startup - this basically runs with the following OPTIONS="-U 
ntp -s -b"
   This just does a one time synchronization at startup

3. Run ntpd - this will make sure your time doesn't drift once it has been 
synchronized

Note: Running ntpd as is wont help especially if you are drifting too much - I 
don't remember the threshold but beyond a certain point ntpd wont try to 
correct the time.

On SMPS, my rule of thumb is: "the bigger the better", since one may
add more devices (drives, cards, fans etc.) in future.  Actually same
goes for chassis too, the more the number of fans the better.  I
prefer to let the budget constrain the choice.

Unfortunately that is the kind of answer I am getting in google. I am not sure 
whether I am asking the wrong question but I definitely believe there should be

[ilugd] New Year Project - "DIY Desktop"

[Mithun Bhattacharya]

I did search for "DIY Desktop" on google and got overwhelmed by the number of 
results it returned.

Basically I am looking for pointers to how to build the ideal desktop. Few 
things for which I dont seem to find answers are:
1. How do I calculate SMP required - I am not even sure what all draws power 
inside a computer !!
2. How do I figure out which chasis is good for my needs - I dont see much 
focus on air flow, number of fan required. Intel says BTX is the recommended 
chasis configuration for the latest CPU's but I cant find any chassis optimized 
for BTX configuration.
3. I do know the CPU, memory, hard disk, graphics and sound capabilities 
required - what else do I need to worry about ?

If anyone has lately given thoughts on these do share the info.

[ilugd] Version control strategy

[Mithun Bhattacharya]

Does any one have any pointers for maintaining a collection of independent 
scripts / very small projects under version control.

To elaborate I have about 200 scripts and 40 folders where each folder could be 
considered a mini project.

I dont think this would fit a standard project layout where we can tag all the 
scripts for each release. It also doesnt seem to make sense to create a module 
out of every script. Changes could be as frequent as multiple times a day to 
maybe once in two years. Almost all the changes result in an immediate release. 

Any thoughts or pointers would be highly appreciated.

It happened to me recently. Was using vsftpd in my intranet on a
Fedora box. Decided to try out Ubuntu-64bit on a new box. So while
formatting the box decided to give /var partition a larger size. To my
horror, when configuring vsftpd on Ubuntu found the default directory
is /home/ftp!!! Now how do I ??? I want to use FDS but my box is
Ubuntu, so should I steal another box for Fedora/FDS sake??

___

So you feel it is bad that someone set the default as /home/ftp yet you wish to 
use /var/ftp or something similar ?

I assume Ubuntu hasn't done anything to vsftpd to not allow you to change the 
default configuration. After all this is what freedom is about - isnt it ? 
Ubuntu can set the default howsoever they please and you are free to set it to 
whatever you please.

As for Enterprise releases I believe they would all conform to the LSB which I 
would imagine include standard destination for FTP folder etc.

1. fdisk -l would tell you the available partitions if any on the hard disk.
2. file -s  would tell you which filesystem it is
3. Since the hardware had a crash - it is recommended you do a fsck on the 
filesystem unless it is a Windows partition
4. Mount should be able to automatically mount all known filesystem without 
specifying it on the command line - if it doesnt work and item 2 & 3 worked 
them pass the parameter -t  to the mount command.

Unknown partition tables... it says for USB storage device (floppy 
/dev/sda) which is seen as SCSI storage. I checked these at screen 3 and 4.

---

USB disks turn up as mass storage devices unlike floppy - did you create a 
partition on the USB disk before copying the drivers on it ? How did you 
prepare the USB disk ? I hope you didnt format the USB disk in NTFS or VFAT.

Though I would have to comment that I think it is very unusual for a distro to 
be intelligent enough to handle a USB disk but foolish enough to ask for a 
partition on it and also foolish enough not to realize that the whole disk is a 
single partition.

[ilugd] Intel 3945 with WPA2

[Mithun Bhattacharya]

Does anyone have success getting a Intel 3945 wifi card working with a wifi 
router configured with WPA2 authentication.

As of now I have had luck with the following:
1. Configured the ipw3945 module and wpa_supplicant
2. I can browse available wifi access points
3. I can use a static IP other than what my Windows was assigned and ping the 
router

The following doesnt work

1. DHCP gives a timeout - windows gets an IP through DHCP without a problem
2. The kernel module doesnt load automatically when I run wpa_supplicant even 
though I have alias eth0 ipw3945 in my /etc/modprobe.conf and the 
preinstall/postinstall setup in /etc/modprobe.d/ipw3945. It works fine if I do 
a modprobe ipw3945
3. I cant ping the router if I use the IP which Windows got before I rebooted 
into Linux

Any suggestion would be highly appreciated.

you have a server where you dont need the graphics card at all or have a high

similar technologies are actually stealing your RAM and are not dedicated 
memory modules.

The price is roughly the same in Nehru Place (might be slightly cheaper),
but the problem is the market is flooded with the v5 model, which can
only run DD-WRT micro as it has half the flash and RAM. It is slightly
more tricky to reflash, and can be turned into a brick if the reflash
is incorrectly performed. I have not been able to find the L model
(equivalent to the v4) anywhere, short of ordering it from Mumbai. Same
with the Asus WL500g.

[ilugd] WRT54GL

[Mithun Bhattacharya]

Just for information sake I bought a Linksys WRT54GL wifi router recently and 
would recommend anyone who is looking to purchase a new router for SOHO use to 
go for it. Other than the fact that it boldly says open source inside and 
actually running a Linux kernel I am currently using it for the following setup.

1. One VOIP phone wired connection.
2. One work laptop wired connection running VPN
3. Laptop on wifi running skype, bittorrent and usual surfing.

I am basically using the advanced QOS feature of DD-WRT which is the opensource 
firmware I have flashed the router with. The basic priority list is as follows:

1. MAC priority premium to VOIP phone
2. MAC priority express to office laptop
3. Bittorent traffic bulk priority
4. HTTP/HTTPS with standard priority

Therefore I have actually called people to solve work related problems on the 
VOIP phone while working on the office laptop while my bittorrent download was 
going on with no bandwidth throttling configured on the application level.

To compare I had initially run the router with the original Linksys firmware 
and I found that no amount of tweaking the parameters could stop my bittorrent 
traffic to not gobble up all the bandwidth.

Re: [ilugd] answer seeking by an admin

[Mithun Bhattacharya]

1. Use lsmod to see whether a new module has been loaded or not.
4. Configure a bootloader like LILO or grub
5. Use smartctl

I am not sure about question 2 and 3. From what I understand every device 
driver available for a OS has a alloted major number. The number used by the 
current driver can be found from /proc/devices The minor number can be variable 
depending upon what sequence the device was loaded. If I am correct then 
question 2 and 3 doesnt make sense. Maybe I dont understand how this works or 
else these questions are not from RHEL exam ?

In one of interview of RHEL I have been asked following question.
Please help me in getting answers

1) Without using dmesg command and messages and dmesg log file, how
one will find that hot pluggable drive just inserted has been detected
by kernel or not.

2) Are device file corresponding to this drive will be created
automatically? If no which command will create corresponding block
device file in /dev.

3) If these is no way for automatic generation of block device, how
major and minor number of a disk can be figured out so that one can
use mknod device_name b maj_no Minor_no?

4) If this disk is configured and partitioned successfully. One has
copied /boo, / , /var and /usr of running system to this disk on
corresponding directory. What has to be done to write bookable super
block /MBR on this disk so that one can boot from this disk on next
reboot.

5) without using dmesg and message file, how one can get prior
information that a particular disk is malfunctioning and going to
crash / fail.

It's too small to make a SF project IMO.  I would do it as a last 
resort (well, sarovar, not sourceforge).  What do you think?

I wouldnt worry about size - I started off with a 100 line perl code which has 
managed to grow into 5 branches over a couple of years. Basically unless 
sourceforge or sarovar prevents you from starting a small project I would say 
go ahead and do it.

That is a SATA hard disk which was not existing when Redhat 9.0 came out. Use

I dont think that attitude has ever helped anyone for any appreciable
amount of time. If you are doing or using something which is meant for
the common mass you have to worry about what they say. Ofcourse we do
have the saying the majority is a fool but still it is a much needed
fool.

Anyway other than that I dont think the URL was presented or commented
on in the right way. My interpretation of why they think Linus is not
needed is because Linux has caughtup with so much of a momentum that it
is running on it's own. Yes Linus does his share of coding and yes he
is guiding the developement process - but what the article says is that
there are enough people contributing to Linux and quite a few
commercial organization are getting to decide which way Linux
developement should go forward. Yes commercial organization do worry
about what will get them more money from the majority unlike some
people who would prefer to stay in their shell.

It depends on your needs and level of confidence in the language.
Ofcourse you already knew that ;). I would recommend you try out a few
of the following before making a decission. You can always write back
with your queries but in most cases you shouldnt have a problem using
either of them.

Pure Templating:
1. Template Toolkit
2. Text::Template
3. HTML::Template

The following can do templating for you but do remember these are more
comprehensive tools and once you have them installed your horizon for
developement grows exponentially. All of them are best used under a
mod_perl environment but most can be used under a CGI environment too.
1. EmbPerl
2. HTML::Mason
3. ePerl
4. Apache::ASP

As I said earlier it depends on what is complete requirement.

Ok I am assuming it is showing full because the filesystem is mapped
all over it. If that is the case
http://www.tldp.org/HOWTO/LVM-HOWTO/reducelv.html should cover the
process.

I have provided the URL for the same above.

I also see another problem - you have only one partition which is
completely dedicated to the LVM installation. A better way out is
usually to create lots of small partitions and then setup LVM over it.

It wont help your current situation but for future reference - what I
did was created 10 partitions of 4GB each and merged them under LVM.
This way I can always pull out any partition if I need it for non LVM
use later without having any headache.

To begin with I would recommend you read the LVM howto
http://www.tldp.org/HOWTO/LVM-HOWTO/ being a good starting point.

Next to summarize there are three major sections in a LVM namely
extents, volumes and volume groups.
To understand them more clearly you could think of Physical volumes as
hard disk or a software raid device, logical volumes would be
equivalent to a partition on that device.
These volumes would be internally split into chunks of data which would
be called physical or logical extent depending upon what type of volume
you are splitting.
Using these volumes you create Volume groups which is where you start
looking at it from outside the LVM therefore your filesystem sits on
the volume group.
Any resize activity you do should be supported by the volume group and
the filesystem sitting on it and everything else will happen
transparently.
Now to free space from LVM and have it usable for Windows you need to
have a logical volume freed from LVM. If you dont need to pass the
whole space to Windows you could ofcourse resize the partition and put
part of it back into the LVM.
Therefore to resize (shorten) a filesystem on LVM you need to do the
following
1. Run pvdisplay on the partition or device you wish to remove and
confirm it is not being used (check for "Free PE"). If it has data in
it - you need to have spare space in other extents in the VolGroup and
then run pvmove.
2. unmount the filesystem
3. Resize the filesystem
4. Run vgreduce to remove the volume from the volume group.
5. Mount the filesystem on the updated volume group.

I would recommend you read the HOWTO thoroughly and understand the
commands I have mentioned. Since I donot know the structure underneath
your volume group and since I dont want you to blindly copy my
instructions I have not mentioned the exact syntax to use. I do believe
I have mentioned all the steps but dont blame me if I missed any step -
it is your data after all :).

1. Do a 'cat /proc/mdstatus' and check whether md still thinks you have
two hard disk in the raid setup.
2. Assuming it shows three or more hard disk with one in failed status.
Run 'mdadm /dev/md0 -r /dev/hdd1' which should remove the failed device
from the RAID array.
3. Run 'mdadm /dev/md0 -a /dev/hdd1' which should add the new hard disk
back into the array.
4. Regularly check the output of 'cat /proc/mdstatus' to see the Raid
array being recreated. If possible try not to shutdown the server till
the array is recreated. Following command might be helpful 'watch -n 10
cat /proc/mdstatus'
5. RAID devices dont necessarily have a filesystem therefore you can't
mount the device/array itself. Assuming your filesystem didnt get wiped
out you should not have to mount anything. RAID will recover itself and
become healthy in the background without your intervention. Ofcourse
system performance would go for a toss meanwhile.

Do note I have made assumptions as to what your devices and raid setup
are. Check the man page to understand what options I have given and
their implications.

Depends on whether you at all have a proxy server or not. I would

1. Crimp a cross cable and connect the laptop to the desktop directly.
2. Set a static internal IP on the laptop
3. Set a static internal IP in the same subnet on the desktop
4. Set the route on the desktop to have a default gateway of the IP of
the laptop
5. Set the DNS server to the server assigned on the laptop

Thats all - the steps are pretty much OS independant so you can pick
and choose whatever OS you feel like. Just make sure your firewall
settings on both your laptop and desktop are properly configured to
allow the IP you are using.

Firstly put it under /etc/fstab - you have better control over the
mounting and unmounting process including unmounting shares while
shuttign down.

Secondly I think your problem stems from the fact that smbfs like nfs
will retry indefinitely if a share becomes unavilable - this can have
serious implications on the server. The way around is to understand how
the hard and soft mount options works. Read the details under the nfs
section in mount and decide which one is more important. Remember hard
mount is the default and that is what you would usually want unless
your apps really know how to handle unrealible network file systems.

So a Meta declaration will override the Content-Type header since
ContentType could possibly be a servier configuration whereas the META
tag is controlled by the person maintaining the page who idealy should
be a better judge of what the document is actually in.

I believe this is very iffy and behaviour may change with even a small
patch to whatever browser you are using - basically no standards on
this behaviour.

Cant recall specific standards but a nice discussion on similar topic
is available here
http://ppewww.ph.gla.ac.uk/~flavell/www/content-type.html
Do note I couldnt locate any reference to the fact that Content-Type
can not be overridden at the broswer end.

> So, in other words, browser should not trust server.

In a hostile network I would prefer not to. I am not sure of the
specifics but bottom line is it is a matter of trust - would I trust a
unknown server to decide how I treat their data or should I be the best
judge of it. I would rather let applications I trust decide what to do
with anything.

I think we have deviated a bit from Charset to Content-Type Charset is
not as strictly enforced as Content-Type.

Yes there are sufficient broken webservers out there who say rpm is a
real media file to give me headaches.

Coming back to http://www.w3.org/TR/html4/charset.html My
interpretation is

1. Check for Content-Type use it if available. Go to item 2 for text
contents
2. Check for META tag use it to over ride server side Content-Type
3. Check for element charset and override the charset for the specific
element

Maybe my interpretation is wrong but I think that is what happens
currently. Also as I mentioned before we are discussing two different
topics here. Content-Type is a superset of charset as in in most
scenarios Content-Type is sent without a charset involved which is why
META tags play a lot of role.

I am not sure which HTML specification you are looking at but the W3
page says quite opposite of what you are claiming

http://www.w3.org/TR/html4/charset.html
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

Basically a sample interaction between a browser and a HTTP server goes
like this in terms of document encoding:

1. Browser sends request to the webserver with the Accept-Charset
header eg Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7. The charset
could be a list in which case the values are in decreasing order of
priority. The q value mentions the allowed degradation in quality of
the content if selecting the specific charset in this case utf-8 or any
charset other than ISO-8859-1
2. Server responds with the charset as part of the content-type header
eg content-type:text/html; charset=ISO-LATIN-7 If none of the
acceptable charset mentioned by the browser is available at the server
side then a 406 response is sent.

The majority of the problem starts now. The standards say that the
content-type specified by the server is a recommendation or a guideline
and not an overriding instruction. The browser is supposed to accept
the data in good faith but is supposed to use it's own judegement in
handling the data. This is the reason why all browser give you an
option to change the charset being used to render the current page.

Next problem is UTF-8 encoding itself. This was developed after UTF-16
and UTF-32 came into the picture primarily because it was backward
compatible with ISO-8859-1. Do note most browser and HTTP server will
default to ISO-8859-1 if a specific character set is not defined.
Therefore the first 127 characters are exactly the same in UTF-8 and
ISO-8859-1 Any attempt at autodetecting character encoding will fail
since there is no way to differentiate between a UTF-8 encoded
character or a two ISO-8859-1 encoded characters. Thats the reason why
you see funny characters on your screen if there is a missmatch in the
server response and the page encoding.

There is a way around it too as mentioned here 
http://www.w3.org/TR/html4/charset.html#encodings Basically if you
follow standards there is no scope for default value for document
character set encoding. You are supposed to specifically mention which
characterset to use to render the document inside the document itself.

This should be at the begining of the document and in english
(ISO-8859-1 has some unfair advantage since it was the first encoding
used on the web) In theory every document should have it and every
renderer should strictly adhere to it - irrespective of what anything
else might suggest - unless ofcourse the user wants to override it. In
practice we all default to ISO-8859-1 and follow the server side
recommendation or specific document encoding if present otherwise most
of the internet wouldnt render at all.

Coming to BOM I refer to http://www.w3.org/TR/html4/charset.html - read
the section "Notes on specific encodings" which seems to say BOM should
be used only if UTF-16 data is present. Also it should be the first
byte to be transmitted to the user-agent - I am not sure whether that
implies it should be before the HTTP headers or after that.

I guess that is all I can think of at the moment. Hopefulyl it has been
of some use.

For transferring emails the easiest way is to setup a IMAP server and
push all the emails into it. That can be later pulled out into
thunderbird or whatever your preferred email client be.

Since you have shown a file listing I am assuming you have mounted the
VCD before attempting to play it.

The recommended way to play a VCD is not that. I would recommend you do
the following:
1. Unmount the CD
2. Run the following
mplayer vcd://1

Maybe you meant to do

mysqldump generates SQL to recreate the table schemas with optional the

Basically most SATA RAID (including non onboard hardware) provide
software based RAID support. You can review the details here 
http://linuxmafia.com/faq/Hardware/sata.html

Intel definitely gives a fakeraid or software based RAID support.

As the above URL will say if it costs too good to be true or is for
free then it probably isnt a proper hardware RAID support.

Bash version will tell you just that the version of Bash you are using.
Simillarly OS fingerprinting will tell you which version of the kernel
is running.

What I have been saying is that to know specifically which version of a
distribution is installed just follow the strategy which the
distribution uses to determine version.

RedHat : /etc/redhat-release
Fedora : /etc/fedora-release
Debian : /etc/debian-release
Slackware : /etc/slackware-release

A distribution is just a collection of packages. It doesn't have any
specific technical information which needs to be standardized across
distributions. What every distribution does have is to consistently
inform the release of that specific distribution which will be
consistent across versions of that distribution.

I guess corporate customers would like SCSI disks, even home users
shouldnt go for anything less than SATA disks.

I do recall NFS having lad issues that definitely needs to be looked
into. Guess we will have to develop a proper set of test cases based on
your feedback :).

I have used pretty simple installations of LVM over RAID5 on Fedora
Core 3 and it did come up in a few min. I do agree complex LVM and RAID

Adding disks would be limited by the enclosure holding them. A highly
modular system I am afraid wont be there in a first cut we would
probably have to set up a research lab or something where CPU and hard
disks both are modular and are being used efficiently.

Also if I add a CPU does it contribute to a existing box or creates a
new box. There are various degrees of modularity which could be
achieved but definitely not everything in the first version.

Haha as soon as I get someone interested in coughing up resources you
can be the beta tester. Unless ofcourse you have some spare cash and
the knowhow to make cabinets suitable for housing hard disks with
proper cooling. I wonder how temperature could be measured in the
cabinet over a period of time - anyone has any thoughts on the same ?

I am hoping you have been encouraging in in your email :).

As for targetting business users - I am not against it but I would
prefer to first see what hurdles I encounter in the proof of concept.

I agree running a business is a different ball game but then I can also
see that there is ample scope for starting one considering the
competition in India is almost non existant because of the price
factor.

err maybe we should take some simple steps before we start targetting
the business users ? Most SOHO users probably can survive without
qouta's - assuming there is absolutely no way to maintain it across
platforms.

To think about it quotas need to be implemented at the Linux end - so
would there be an issue if a web based interface is provided to manage
quotas or am I looking at the problem differently ?

Hmm I am not sure how easy it is have a custom built hot-swappable SCSI
drive based setup in Delhi. Of course the cabinet is the biggest
problem at the moment.

If you have any plans for setting up a business I don't see a reason
why you shouldn't agree to have a SLA.

For me making money is not important. It is more of saving money for
personal use. I would like to be able to do it for the sake of doing
it.

[ilugd] NAS idea

[Mithun Bhattacharya]

I have this brewing in my head for quite sometime and was wondering
whether anyone was ready to try it out. I currently cant due to lack of
resources but if it works you could probably earn some glory/money
whatever.

Basically I am looking at a Linux based NAS solution. Unless I am
mistaken most NAS systems are costing 5-6 times the cost of the
hardware involved.

If my understanding is correct a simple NAS is:
1. A storage space available over the network
2. Fault tolerant
3. Expandable
4. Transparent
5. Compatible across OSes

The way I see it is I need the following to get it going
1. Gigabit network
2. RAID 1/5
3. LVM
4. RAID and LVM can be configured to handle hot swap
5. Share disk space using NFS/SAMBA

Of course it runs Linux or I wouldn't be talking here. There are two
things currently lacking off the shelf.

1. A cabinet to hold/expand hard disks at least 4 hard disks to begin
with
2. A web based application to manage the RAID and LVM setup.

I am hoping I am making sense here and would like to solicit feedback
as to the viability and interest in trying out the setup.

[ilugd] Promise Fastrak TX2300

[Mithun Bhattacharya]

Has anyone been able to do a fresh install of any distribution on a
desktop with the above mentioned SATA RAID card ?

As of now FC4 installer says no hard disk found even if I force it to
load the sata_promise kernel module. It is quite possible the kernel
version with that installer was not aware of the particular RAID card.
I am not very sure what all RAID cards this particular module supports
- is this information available anywhere specific ?

Couple of things in this context:

1. -r option is for recursive download A more preferable option is to
use -m mirror option assuming you want to maintain a local copy and not
take a snapshot.
2. To ensure you can read the whole thing offline you might want to use
the -k option. Revewing the wget documentation I think you might want
to do "wget -m -k -K -E"
3. Do you have any specific requirement for downloading the complete
website - is it for offline reading or for taking a backup ?

  Order allow,deny  Allow from All

2. Why do you need to enable ExecCGI on your document root ?

3. Are your scripts given execute permission ?

Are you sure /dev/modem is symlinked to /dev/ttyUSB0 ? Try running
minicom on /dev/ttyUSB0 and give appropriate AT commands - it is a

You basically need to do two things :
1. Boot from a reliable media - could be pxe, knoppix, zipslack
anything as long as it is not from the corrupt hard disk.
2. Ensure sufficient disk space is available to the OS once you have
booted from something. This could be a CDR, DVDR, local hard disk, USB
drive, NFS mount, FTP server, another linux box with SSH on it.

The choice is yours to make depending on what you have easily available
at your end.

You would need space to save the data you can retrieve. Therefore
either go for a new hard disk with minimal OS installed or you have a
machine with sufficient disk space accessible using knoppix.

The only thing which can make the filesystem driver throw an error is
if the physical media is absent.

Since this is a hard disk and I assume a non hot swapable one - your
media has had a failure. Just get it replaced and use a different media
to boot your OS before you try to retrieve anything from this one.

Once it runs out of physical memory new request for memory would result
in swap usage. If you manage to use both the physical memory and the
SWAP the OS will return a error.

How the error is handled by the application is very application
specific but it would definitely exit - either gracefully or core dump
on some illegal operation.

If it is for HTTP traffic only you might want to consider doing it

[ilugd] Negative Responses

In the last few days I seem to notice a lot of negative feedback. The
linux versus freebsd performance thread being one but not the only
thread receiving answers which could potentially have been toned down.

I do agree Sandip could have asked more specific questions if he wanted
specific answers but I don’t agree that he crossed the line of asking
others to do his homework.

Lets keep this a cheerful and a fun place to ask questions.

Never too late to catchup I guess :).

Some highlights pasted from the website 

-
MySQL 5.0 is the most ambitious release in MySQL's history. MySQL 5.0
delivers the enterprise features the community has been asking for,
including Stored Procedures, Triggers, Views, Information Schema, XA
Distributed Transactions, and new Storage Engines. We also added Strict
SQL Mode to eliminate some of the ‘Gotchas’. Plus, MySQL 5.0 builds
on our reputation for Reliability, Performance, and Ease of Use.

There is hardly any language left in this world where you couldnt
implement any specific logic due to the limitation of the language.

It's true that some languages come bundled in with extensions to
simplify your work with specific situations but lets not take it for
granted that those specific situations are required by everyone.

As Sandip mentioned earlier that is not specific to python and can be
easily done for developement in any language.

I dont think Raj was talking about Templating mechanism. Yes templating
is important. Yes it is also highly missused. Missused in the term that
the template shouldnt drive the application rather the application
should drive the template.

What Raj is talking about is separating the business logic from the
templating mechanism. I dont know much about PHP but I guess Raj is
saying these two layers are not actually independant layers in PHP
based implementations.

I would say most novices need templating mechanism whether they use a
standard package or whether they rig up something of their own is what
differentiates a novice from the expert.

Agreed and atleast I am not bashing PHP as such but targetting more the

If you will notice I dont usually go out of the way to promote Perl

Interesting question - why do programmers think that just because his
limited knowledge perceives a script to be junk whereas it could be
invaluable for the enterprise ?

I would prefer if everyone wrote his code as if he was writing a
enterprise application and then the programming world would have better
things to do than figure what the previous developer was high on, while
writing the code, he is maintaining.

Lets forget all the other trivial websites and talk about Yahoo. One it
started with Perl as the backend language and two now a days it uses
everything from Perl, Python, C, LISP and god knows what else... so umm
stop this pointless discussion of my language is better than yours.

I know a few ex employees of Yahoo on this list who might enlighten us
all as to what really works and what doesnt work there..

Personally I think it is the employees more than the language who can
really make an enterprise grade application. I have seen enough crap
code in all the languages where I have spent any amount of time.

Firstly a PC can not boot without RAM. Since the PC seems to have
powered up and the boot loader also got loaded I am assuming there is
some sort of damage to the hard disk. I would recommed a backup disk be
created and then you should start looking at what you can retrieve from
the damaged hard disk.

The other reason the boot loader would be confused are:

1. Extensive filesystem damage - you are better off with the backup
disk in any case then
2. Power went off before lilo could write to the boot sector - only
valid if you were playing with lilo and only if lilo couldnt write
before power went off.
3. If you use grub then /boot/grub folder or /boot/grub/grub.conf or
/boot/grub/menu.1st on Debian got corrupt.

Do note if power wasnt the culprit then either the kernel was non
standard or the motherboard is dying on you.

The list guidelines are available at

The third item clearly says offtopic postings should be avoided.

Also I donot think everything which can be mapped to the GNU principles
can be accomodated in this mailing list. This list is specifically for
people and topic related to Linux. It would probably be off topic to
even discuss how Free BSD and GNU go together. The same applies for all

Re: [ilugd] 17" plasma/lcd monitor recommendations

[Mithun Bhattacharya]

I have a DELL UltraSharp 1704 which gives me 1280x1024 @ 32 bit color
according to windows ..

I dont think you will find a 17" TFT which gives you 1400x1050
resolution.

Also this LG of yours is a TFT or a CRT ? I am surprised to hear you
are getting 1400x1050 on a 17"CRT - arent they equal to a 15" display
area ?

Do note a TFT will always give lesser resolution compared to a equal
viewable area CRT. Also fast moving images dont render too well on a
TFT unless you are ready to sell your kingdom for it :).

Something I noticed which doesnt seem to have been mentioned is the
fact that it seems both Acer and Limpus are of Taiwan origin. Also
Limpus seems to be able to run KDE but all text is in chinese. Maybe
this was somebody's quick fix / lowcost option to promote taiwanese

I have no idea never used it myself - I cant imagine it being a too
heavy module. I would say resource requirement would depend on the
number of servers being managed rather than the volume of traffic. Best
thing to do would be to setup a test environment and try some load
testing.

The idea behind backhand is that you have a single apache installation
working as just the load balancer. You can keep a apache 1.x
installation for mod_backhand and keep your application on Apache 2.x

Isnt the jetdirect method applicable to laserjet printers connected
directly to the network ?

I didnt notice any way to configure socket option in CUPS - is this
automatically available on my setup ?

Doesnt this imply I have to setup a raw data queue with printer driver
loaded at the client end ?

My basic problem is that I am having a ancient DeskJet printer which
doesnt have driver for Windows XP. It works great from Linux even in
color. I am not sure what all I need to do to get my CUPS working with
Windows. Do I have to provide a driver to Windows even in my setup ?

Ideally I tell Windows to use CUPS via IPP for a Postscript printer and
then CUPS manages the rest. Is this feasible or am I looking at an
impossible situation ?

SAMBA is another option independant of IPP. I am trying to minimize the
number of server I need to run CUPS in theory should be able to manage
everything.

[ilugd] Configure windows to use CUPS

[Mithun Bhattacharya]

Hi,

I am trying to configure a CUPS based print server on windows using
IPP.

Windowx XP does seem to have the facility to enter a printer using a
URL.

At CUPS end I have configured a HP Deskjet printer as DeskJet and set
it as the default printer.

My question is - what exactly is the URL I am supposed to provide to
windows to be able to print using IPP ?

I gave http://192.168.0.100:631/printers/DeskJet but Windows doesnt
like it even though I can see it using a browser on the same machine.

[ilugd] Indexing the mailing lists

[Mithun Bhattacharya]

Hi,

I was wondering whether there is any consious decission not to allow
the mailing lists to be indexed by the search engines. There has been
quite a few emails I would like to refer back to but I find them
impossible to find on google atleast.

I believe we have a pretty decent sized archive of both the LUGD and
LIH mailing lists which should have quite a bit of useful information
for the world in general :).

Re: [ilugd] How to create a new linux user on the fly

[Mithun Bhattacharya]

Couple of things that can be done are as follows :

1. You use suexec and take let AMS have fun with his bots.
2. You do a sudo and have the same problem as above. In both cases you
just hope there are no bugs in your implementation which would result
in your system being hacked or made useless long before you realized
what has happened.
3. You use the web front end as a queuing mechanism and allow a
separate superuser process to implement the creation process. Better in
the sense that your application is modular and each module does what it
is good at. Throw in a authorization step and the whole thing is a
little more secure.
4. Do you really need to change the system setup ? Most requirements
can easily be fulfilled by implementing a separate authorization and
authentication mechanism which is independant of the system accounts.
This can only be answered by you and the answer would probably be valid
for your specific case. Look at what CVS and Vpopmail does to handle
situation where they have multiple users accessing the server but dont
necessarily have anything to do with a system account on the server.

SQUID is using 98% CPU or RAM ? I dont see the relationship between 98%
CPU and lack of SWAP usage.

While you are at it can you tell the CPU and RAM usage at the time of
bottleneck ?

Also take a diff of your squid.conf against the default one provided by
your distro and paste the result.
