ok. But in this case, I am not able to run smartctl on the hard drive. It is

 If you still decide to replace the disk with a newer one, I'd copy the
 data from an off-line system (e.g., from a LiveCD). If data is still
 fully accessible you can use any tool you prefer for the task.
 
 When it comes to cloning a full system I like Clonezilla (or the like)
 applications.
 
 And for deep data corruption that lead to data lose there are specialized
 tools such PhotoRec/TestDisk that can help you with recovery.
 

got it. Thanks.

 Can someone recommend a hard drive manufacturer/model that is more
 resistant to developing badblocks? The drive that gone bad is an iomega
 prestige portable USB 3.0 external hard drive.
 
 For a company I prefer to choose those hard disks tagged as enterprise
 with 5 years guarantee (since I switched to SATA I always buy Seagate).
 

For me the badblocks seem to be developing after couple of years no matter 
what the hard drive is. May be I am doing something fundamentally wrong. 
What surprised me is that this is a back up drive and not used heavily at 
all. I guess iOmega drives are not very stable.

 Also, I tend to avoid as much as I can those external hard disks that
 came integrated along with the enclosure: I prefer to buy the case and
 the disk as separate items so I can choose the best devices in the market
 and also by doing it this way I can replace the hard disk in the event it
 breaks or should I need more space :-)
 

This one is very slim and does not even have an external case.

 I don't know, but in my experience, USB-connected hard disks
 suffer these problems much more than PATA/SATA/eSATA/SCSI/SAS

What about solid state hard drives that can be connected via USB drive? I 
heard solid state hard drives are more dependable (but expensive) than the 
usual (IDE?) ones. Does USB connection matter there too?

Thanks for answers to my other questions as well.

 I guess iOmega drives are not very stable.

 
 I have several external drives from iOmega that are a few years old. But
 the drives inside the enclosure are Western Digital.  I've never had a
 problem with them.

How old is your oldest iOmega drive that does not have any problems? Can you 
please give me its model?

Is the drive usually operated at room temperature or is it usually operated 
in a controlled temperature environment (ex:- in an office where the temp is 
always maintained at a specific level)

Also, how do you usually partition the drive (using fdisk/cfdisk and then 
mke2fs to create the file system or some other method?)

I am asking all these questions just to see where things might be going 
wrong. Usually my drives work fine initially. After 3-4 years, they start 
developing bad blocks. They are usually at room temperature (no air 
conditioning), partitioned via cfdisk + mke2fs.

e2fsck errror: Error reading block (Attempt to read block from filesystem resulted in short read)

2012-08-28 Thread Kamaraju S Kusumanchi

When I ran

$sudo e2fsck -c -c -f -v /dev/sdb7

I am getting a lot of errors such as

Error reading block 18022401 (Attempt to read block from filesystem resulted 
in short read) while reading inode and block bitmaps.  Ignore errory? yes
Force rewritey? yes
Error reading block 19562497 (Attempt to read block from filesystem resulted

Force rewritey? yes
Error reading block 19824641 (Attempt to read block from filesystem resulted 
in short read) while reading inode and block bitmaps.  Ignore errory? yes
Force rewritey? yes

1) Does this mean there are badblocks on my hard drive?
2) Am I correct in choosing yes to both these questions or is there a 
better way?
3) Is the drive going bad and need to be replaced?
4) What might have caused this problem and how to prevent it in the future?
5) Is the filesystem on this partition corrupted?

 I don't get that behaviour although I'm using a different set of tools

When you say it works fine here, does it mean that knode under GNOME does

First of all, make backups regularly. Make the process automated.

As for the testdisk, I have used it before and it is AWESOME.

OT: cannot copy text from matlab to putty

2012-01-16 Thread Kamaraju S Kusumanchi

After logging into a windows 7 machine, I connect to a Debian stable machine 
by ssh via putty (0.62). Now I fire up matlab (7.9.1.671 R2009b) from the 
Linux machine.

The problem is that I am not able to copy any text from Matlab's command 
window to vim/shell (opened via putty ssh connection to the Linux box). The 
copying does not work to any other windows application (ex:- outlook) 
either.

FWIW, I am able to copy text from shell/vim/outlook to Matlab's command 
window. So, the problem is just one way.

I am using xming 6.9.0.31 as the X server.

I tried looking in google but is of no help. Any other comments/suggestions 
to look into before I give up?

 So the problem is that you cannot copy text from the linux session
 (client) to the Windoof session (host) through the Putty session. Yes?
 

Not exactly. The problem occurs with matlab command window. I can copy paste 
text between vim sessions, vim and shell, shell and outlook. Here vim, shell 
are opened via putty by sshing into the Linux box.

 
 I tried looking in google but is of no help.
 
 Someone typed google into google and broke the internet. It was

This does not help much. The usual copy pasting is not a problem. The 
problem is the specific case of copying from matlab command window to 
another putty session or to a windows application.

 (client) to the Windoof session (host) through the Putty session.
 Yes?

 Not exactly. The problem occurs with matlab command window. I can
 copy paste text between vim sessions, vim and shell, shell and
 outlook.

 Is this a single Putty session you are talking about?

The effect is the same whether it is the same or different putty sessions.

 I have no problems copying commands within ssh sessions or across
 different ssh sessions, including to matlab. (Debian Squeeze)

 I've never tried using Windoof 7 and Putty to access Matlab.

Well, I think this one is a corner case. There are 4 things involved here 
windows + xming + putty + matlab. One of them does not speak to the others 
properly.

port direction definition

2011-12-26 Thread Kamaraju S Kusumanchi

I have laptop - router - internet. The router is Westell A90-750015-07. I
am using Verizon DSL High Speed Internet.

I have set up the apache server on port 8088. It works internally but not
externally. So http://192.168.1.21:8088 works. However, I am not able to
access the site if I try http://192.168.1.1:8088 or
http://72.88.231.219:8088

I tried to set up the port forwarding in the router, but this process is
very confusing.

Consider these snapshots for example...
snapshot1.jpeg -
https://docs.google.com/open?id=0B4J6QB3eL1ZZYTcyNzNjNTYtZDY5OC00YTMzLWIxM2YtYTVmMTZkZjk3YmRh
snapshot2.jpeg -
https://docs.google.com/open?id=0B4J6QB3eL1ZZMzc3NWY1OTItMjYxMi00M2VmLThjMjEtNDRiZTc2ZDM4YTM3
snapshot3.jpeg -
https://docs.google.com/open?id=0B4J6QB3eL1ZZM2Y4MzBjNDMtOTM4Yy00NmU4LTliZGEtMjkzMzJlYzk2NDAw

In the router configuration (192.168.1.1), I chose Firewall Settings -
Port Forwarding and I get snapshot1.jpeg. I then choose Add. This gives
snapshot2.jpeg. There is no rule relevant to forwarding of http packets, so
I click on create which gives snapshot3.jpeg.

In snapshot3.jpeg, the field (1) Enter a name for the custom service: can
be any random name. But what about (2)? Should I choose Port Forwarding
or
Port Triggering.

The options in section 3 of snapshot3.jpeg are even more confusing. Under
the Protocol, there are three options - tcp, udp, both. I guess I should
choose both?

For Global PortStart, Global PortEnd should I choose 8088?
For Base HostPort, should I choose 8088?
What about Direction? In/Out?
If the Direction is In, then Port Direction can only be Dst.
If the Direction is Out, then Port Direction can be Dst or Src. Which
Port direction should I choose?

Thanks for any help. This is utterly confusing to me. No amount of googling
helped me. There is no help page for this router. Did anyone get this
working or is my best choice to buy another router?

thanks for any help

 Forwarding or Port Triggering.
 
 Select Port Forwarding.  Port Triggering is used to dynamically make a
 selection based upon outbound activity.  But in this case you want to
 make a static configuration.

I followed yours and Andrei's suggestion and it worked like a charm. I chose 
Port Forwarding, Protocol=both, Global PortStart=8088, Global 
PortEnd=8088, BaseHostPort=8088, Direction=In. Then assigned this service to 
my laptop.

 What about Direction? In/Out?
 If the Direction is In, then Port Direction can only be Dst.
 If the Direction is Out, then Port Direction can be Dst or Src. Which
 Port direction should I choose?
 
 That is very confusing to me.  I vote to select In.  But I do not
 understand why it would provide an option for Out.
 
 After setting this up it is possible that the port forwarding will
 only work from the external network inbound to your internal network.
 That is, testing from your internal network may not be possible.  This
 is because it would require your packages to exit your internal
 network, then be translated through the NAT function of your router to
 the external router address, then the router would need to realize
 that it matches the external router address and route it back down the
 same interface.  That feature is often not allowed.
 
 Meaning that you will only be able to test if this is working from an
 external network.  I often do this using an ssh connection to a text
 terminal and then using lynx, w3m, or elinks to poke at the web site.

You are absolutely right. It does not work internally but if I go to an 
external machine and view the website it works. I've previously tried the 
same configuration but I was always testing it internally. So, it looked as 
if it did not work.

Thanks for all the help.

 Yes. Note: since I have to mess with the ports when doing the port
 forwarding I prefer to let the service always run on it's default port.
 Makes things easier in a lot of cases.
 

The various posts on the internet suggested that Verizon blocks port 80. To 
eliminate that, I was using 8088. I just now checked... the web server works 
on port 80 too!

OT: recommend a book for lamp

2011-12-24 Thread Kamaraju S Kusumanchi

I know a little bit about Linux but nothing about apache, mysql and php 
(other than installing the corresponding debian packages). Can you please 
recommend a book that covers all these topics so I can get a simple website 
up and running by the end of reading it?

I was looking in amazon and found this interesting - 
http://www.amazon.com/Open-Source-Development-LAMP-Apache/dp/020177061X . 
But this was written in Dec 17, 2002. Considering that it was published 9 
years ago, the content is outdated(?) and may be I need something new? Any 
idea?

There seem to be good references on each topic... is that the route to take? 
If so, what do you recommend for each?

thanks in advance

I want to extract sound from a youtube video (I dont care about the video 
part, only sound). I did

$ ffmpeg -i /dev/dsp -o /tmp/song.mp3

However that does not seem to work because I do not know how to tell ffmpeg 
that the video has finished and give me the output.

If I press ctrl-c, the command gets killed.
ctrl-d does not seem to have any effect.

I am using Debian squeeze on Dell Inspiron E1505 laptop.

When I boot from scratch, the network works fine. However, if I do sudo

works after that.

 Can you open another account and safely experiment?
 Or install clean Squeeze in VM?
 I am not expert at all but I don't think that have something with your
 ~/.kde, I think it has to be something with KDE library.
 

On this machine, I already upgraded the KDE packages to squeeze. Even then 
the window was not popping up.

However, A reboot fixed the problem. So, I am guessing that, during the

 $ xmodmap -e keycode  20 = underscore minus underscore minus
 
 That swaps minus and underscore.

Yes. This works and it is just great. Is there a solution when the machine 
does not run X?

map '-' to '_' and '_' to '-'

2010-11-12 Thread Kamaraju S Kusumanchi

While working on my Debian box (which btw is a mix of Lenny and Squeeze), I 
find that I type the underscore character ('_') more often than the dash 
character ('-'). It could be file names, variable names while writing code 
etc.,

Typing '_' involves holding the shift key while typing '-' does not involve 
any. I am wondering if there is a way at the OS (or shell) level solution to 
remap '-', '_' one to another so that typing '_' does not involve holding 
shift key but typing '-' does.

Any ideas/comments/suggestions/pointers etc.,?

thanks

 You need a newer kernel, probably the one from squeeze.

Could you please elaborate why I need a new kernel? Where is the

what is the difference between w95 FAT32 and w95 FAT32 (LBA)

2010-08-21 Thread Kamaraju S Kusumanchi

While running cfdisk, it lists various file system types. Is there a 
document which explains the difference between similar file systems?

In particular, if I want to have a windows XP type of filesystem, do I go 
with 07 HPFS/NTFS or 86 NTFS volume set or 87 NTFS volume set?

Similarly, If I want to create FAT32 partition so that I can exchange files 
between windows and Linux, should I go with 0B W95 FAT32 or w95 FAT32 
w95 FAT32 (LBA)

What are the advantages in choosing one over the other? I tried to google, 
/usr/share/doc/util-linux etc., but could not find anything useful.

Re: Software to handle bits and pieces of information.

2010-08-04 Thread Kamaraju S Kusumanchi

Gary Roach wrote:

 Hi;
 I could use some suggestions. I seem to collect a lot of snippets of
 information scribbled on pieces of paper, old napkins, etc. Examples are
 notes on harware, sources for stuff, notes on possible projects, book
 that I might want to buy in the future and on and on. This has generated
 numerous scraps of paper and sticky notes with the result that chaos
 reigns. I recently tried knotes which helped a lot but didn't cover
 tasks. I have now switched to Kontact. This takes care of scheduling
 things, projects and short term notes. I still am not sure what to do
 about those notes that could be around for a long time like maybe  a
 note on the proton boron fusion reaction energy . I may never use it
 but would like to be able to find the information if need be. I guess I
 need a repository for disparate information (how's that for fuzzy). I
 hope this makes some sense.
 
 Any suggestions.
 
 Gary R

I usually have a directory where I keep all the relevant note files. If
the information falls into a specific category (ex:- calendar based events,
todo stuff, where you stopped reading a particular book :-) etc.,) I'll
have a separate file.

If the information is a random tidbit (ex:- Capital of Libya is Tripoli
and for some weird reason you want to note that down :-)), I just use a
plain text file to jot it down. I normally have some conventions (ex: tags,
delimiters, content separators) within that file, so that I can write a
script to extract all the relevant information as and when needed (ex:-
give me all the tidbits related to Fortran language, all the research
papers written by a particular author). I guess you can use some database
query language if it becomes unmanageable... but I never had to go that
far.

It takes some time to set up this kind of stuff and come up with conventions
that work for your case. But I honestly believe that all you need is a good
editor like vim, grep and sometimes find. I am saying this after having
tried some GUI applications, applications where the information is stored
in a non-greppable format. YMMV.

 While this is beneficial to Debian, it is often not beneficial to the
 user (except for indirectly, since what benefits Debian, benefits the
 user). It would be best if this is done in a testing environment,
 outside of the actual production machine.
 

What do you do if you had access to just one machine (say your personal
laptop) and don't have the luxury of running multiple machines (one for
testing and one for production etc.,)? Sometimes, it is better/practical to
jump the wagon little bit ahead of time and do some testing, before
settling down with the stable version for the next 2-3 years.

If you are administering a system that is used by multiple users, then of
course, it makes sense to wait until a new stable version is officially
released.

keeping the title of konsole window fixed

Is there anyway to keep the title of the konsole window fixed?

I usually have multiple konsole terminals open. Each of them often contains
multiple tabs. I like to set the title of each konsole window manually and
do not want it to be changed dynamically. Is there any way?

I know that ctrl-alt-s can change the title of the tabs. I am looking for a

I think LD_LIBRARY_PATH is what you are after. Also take a look at -B option

sudo apt-get install libc6-dev=2.7-18 gfortran=4:4.3.2-2

(I think) That will downgrade your libc6-dev, gfortran as necessary.

syslog is full of wlan0: switched to short barker preamble

2009-09-07 Thread Kamaraju S Kusumanchi

My /var/log/syslog is full of messages such as

Is there anything I can do to get rid of these messages? Google did not
yield any useful hits (may be I am using the wrong keywords).

ftp access for debian security updates

2009-08-19 Thread Kamaraju S Kusumanchi

Is there any ftp mirror for debian security updates? When I looked at
http://www.debian.org/security/ it just lists an http mirror. However, on
this machine http is not allowed, but ftp is enabled. That is why I am
looking for an ftp repository.

Any ideas/comments/suggestions?

Re: Safest maintenance of a sid system

AG wrote:

 Hi
 
 Having recently upgraded to sid, I want to try to ensure that I am able
 to maintain a more or less stable system under those circumstances and
 in the full knowledge that, by definition, sid is unstable and may be
 subject to breakages.
 
 With this in mind, what do the more experienced sid users do in terms of
 the daily updates of packages that come through - for example - the
 Update Notification?  I know that sidux users rely on some scripts -
 sxmi and sgfi (??) I think - but I wonder if that is what native sid
 users rely on or do you have your own recipes for maintaining reasonable
 stability?  For example, the use of scripts such as those from sidux, or
 not doing a daily system update or ... ?
 
 Thanks for any tips/ steers.
 
 AG

Install apt-listbugs, apt-listchanges. Upgrade packages only if you know why
you want to upgrade them. If you don't know why you are upgrading a
package, you don't need that upgrade. Those are my rules when upgrading a
sid system.

Also, over the years of using a SID system, you'll have a feel for which
upgrades can be trusted which might break your system etc., For example, I
never had problems upgrading gcc, coreutils etc., But I do not rush to
upgrade to the latest KDE apps. YMMV.

You are kidding, right? 

It actually depends on what you are using it for. I use GUI-less systems all
the times for programming. They are as useful as a GUI system.

This is not to say that GUI is useless. For browsing, emails, reading pdfs
etc., I use GUI based systems.

Both have its advantages, disadvantages. The trick is to make the right
choice.

 I recently re-subscribed having been off for about four years.  The
 changes I have noticed are:
 
 1. Much less traffic.  I previously got 250+ posts per day.  Now 50-100.
  Could this be due to the development of ubuntu?

May be. But I also think it is because the quality of Debian packages,
packaging process (having Sid, testing, stable, experimental, backports),
bug reporting process have improved a lot in recent years. As a result, a
user of Debian does not need to constantly write emails to d-u for support.

 5. Less newbie posts.  Ubuntu?

I think so. But I am also glad that it is that way.

 7. Less spam.

Totally with you on that. The mailing list managers deserve kudos for doing
such a great job.

Install the openssh-server package on the Debian server machine.
Start the ssh server (as root) by doing
  /etc/init.d/networking restart

Install an ssh client on MS windows. I prefer putty for an ssh client. YMMV.
Enable X11 forwarding in putty

Install and start an X server on MS windows. I prefer xming.

Connect to the server... and you are good to go.

Long time ago, I did something like this. I first converted the mp3 to wav,

forgot the tools, commands to achieve this. Sorry! Google might be of some

 While you may think its terribly inefficient, it isn't really.  A fancy
 wait function is just polling anyway, you're just making it overt.
 You also have the ability to have proga and progb only touch the file if
 they complete successfully.  If you merely wait until their ps
 disappears, you don't know if they crashed or properly completed.
 
 Doug.

Good point. I'll have to think about corner cases like these furthermore.
The scenario you portray does sometimes occur. The suggestions I got in
this thread are very helpful. Thanks guys.

OT: launching jobs in a combined serial parallel way

I have three programs - say proga, progb, progc.

proga, progb are completely independent. They take couple of hours to
finish. The time to complete proga, progb are not same.

progc should to be launched only after both proga, progb are finished. progc
takes another couple of hours to finish.

What is good way to automate this problem (that is no manual interaction)? I
prefer to use nohup since sometimes I have to log out of the machine before
the whole process finishes.

Currently I have a shell script that works as below.
1) launch proga, progb in the background using nohup.
2) Ask proga, progb to write a file when they finish.
3) Every five minutes check if these files are present. If they are present,
launch progc.

This gets me going for now. But it looks terribly inefficient. I would
appreciate if someone can provide a better solution.

Using Debian Lenny (Stable).

 In a shell script, run proga and progb in the background, then wait
 for them both with the wait builtin.  Something like this:
 
 #!/bin/sh -e
 # -e flag will abort on any error
 proga # Start proga in background
 progb # Start progb in background
 wait   # Wait for whichever finishes first
 wait   # Wait for the other one
 progc  # Now run progc in the foreground
 
 Scott.

This is great. A little perusal of 'man wait' gave me a better idea.

nohup proga 
pa=$!
nohup progb 
pb=$!
wait $pa $pb
nohup progc 

Thanks a lot. Just what I am looking for.

Re: OT: launching jobs in a combined serial parallel way


 Are progs ab yours?

Yes. They are mine.

 If so, how about having each one check ps for the 
 other one as part of it's exit. If the other one isn't running, start
 progc before exit.
 

That is a nice idea. I have not thought about it. For now, I will go with
Gifford's tip of using the shell's wait function.
