I'm trying to change the CMOS battery in the above old notebook that I use with my ham radio station (old is good around a lot of RF). Does anyone know the secret to getting this thing apart? It seems to be held somehow in the middle under the lower keyboard.

One way this can be done is to preload an alternative to the "open" file system call.
Another way is to create a new file-system kernel module which implements the appropriate open call for files within that particular file-system.
The "union" file-system concept is that if a file cannot/should not be written to then a copy of this file is created in another location and this copy is written to. This has been implemented in both the above ways.
The "cowdancer" Debian package implements the "preload" way.
The "aufs" and "unionfs" kernel modules implements it the file-system way.
All three programs are available under FOSS licenses. May the source be with you!

Hi there,
I'm looking for info on how to fix my login after performing dist-upgrade. I'm running Deb. Etch. I can sign on a root via term.
However I get errors like...
Could not open Network Socket, make sure dcopserver is running. And this one....
Could not start kstartupconfig. check your installation. When signing onto my user account.
I opened Kuser and crated a new login and that works. But I'd like to fix my old one.
Thanks, Christopher Cole

It sounds like something in KDE broke when you updated it - or you may be trying to run something (maybe in your .bash_profile?) that worked with the old KDE version but fails with the new one. Hard to say, without a whole lot more info.

I'm not sure of what you mean here. If creating a new account works, then just remove the old one (make sure you don't delete your home directory, of course) and recreate it. Based on your description, that should fix the problem.

How did you "perform" the dist-upgrade?

via an xterm?

Could you please give the commands you typed and the errors which were returned for each command. It is difficult to know where the problem is if the exact error is not known.

So far, issues of LG have been compressed using tar and gzip. Is there any intention to use tar with bzip2 for future issues? Since most of the files in each issue are text files, bzip2 is more efficient (in terms of the size of the compressed file) than gzip. Here is a comparison of bzip2 and gzip using the current issue; i.e. November 2007 (#144):
1028042 lg-144.tar.bz2 1045337 lg-144.tar.gzIMHO, providing a bzip2 compressed format of LG issues would save some download time.

As I recall, we had a similar discussion here in TAG quite a while back (digging through my 'Sent_mail' says 2002 - but I can't find it in LG. Annoying, that.) In any case, here's the comparison that I ran then:

Given that there's no appreciable gain to be had by changing - and that a change may occasion problems (e.g., it would break any automated scripts that download and decompress the monthly archives), I don't see it changing any time soon. I'm usually pretty reluctant to change things like this without a really compelling reason.

I recall finding out about and playing with 7zip well after this discussion; I don't recall being particularly impressed with it one way or another. Looking at it now, one reason, at least, stands out:
From the man page:
Backup and limitations
DO NOT USE the 7-zip format for backup purpose on Linux/Unix because :
- 7-zip does not store the owner/group of the file.
Compression-wise, using my 'Sent_mail' archive (I've trimmed the output
for readability):

It's also slowest,
by a large margin. TANSTAAFL, I guess.

I have SUSE 10 on my PC and installed Ubuntu which has partitioned my hard drive. I want to reformat the hard drive to allow a clean reinstall of Ubuntu 7.10 only from a desktop CD. I've tried using "fdisk" but get the error message "Unable to open /dev/hda" which suggests a problem somewhere, yet Ubuntu currently runs with out any problems. Do I continue with fdisk? If so, how? Or try something else? Once reformatting is successful, will the PC boot directly off the CD or do I need to make a boot disk of some kind? Many thanks for any tips.

Is your master hard disk an IDE HDD or a SATA HDD? I've come across a similar problem when trying to install Slackware 12.0 on a PC. Then I realised that the PC's specifications contain a SATA HDD, so I used cfdisk to reformat /dev/sda, which was the master HDD.

I think Rick Moen has somewhat addressed this problem in this month's thread "uninstalling linux". His tip is to boot your PC with a live CD/DVD distribution, then execute the following command to reformat your hard disk:
dd if=/dev/zero of=/dev/sdXX bs=512 count=1In the same thread, I also talked about using Knoppix to wipe out all partitions on an HDD. Just in case you haven't come across this tip, I've reproduced it below:
A "quick and dirty" way is to get yourself a copy of a Knoppix distribution. Perhaps from Knoppix 5.x onwards, maybe from 3.x onwards would also do the job. Here, I assume that you use Knoppix 5.0.1 or 5.1.1 CD/DVD distribution.
[1] Set up your BIOS to boot a CD/DVD drive first.
[2] Boot up the Knoppix live CD/DVD. This will take a while to load X and get you into KDE, a graphical session under Linux.
[3] Once KDE is ready to use, locate the "K" icon in the bottom-left corner of your screen. This is the menu for KDE, similar to the "Start" menu under Windows XP.
[4] Click on the K menu and locate "System". You need to be patient with live CD/DVD distributions, depending on your system's hardware specifications. Once the "System" menu pops up, click on a program called "QTParted". I think there are two icons for this tool within the "System" submenu:
1. QTParted (create, reorganize and remove partitions) 2. QTParted (QTParted)You can choose either of these two programs.
[5] I assume that you're using IDE HDD(s) and IDE CD/DVD drive(s). Once QTParted is up, you need to familiarize yourself with the "Device" tree on the left side of the program window. If you have two IDE HDDs, then your master hard drive will be /dev/hda (this is also the case if you have only one IDE HDD), and your slave drive will be /dev/hdb. Your IDE CD/DVD drive(s) will be /dev/hdc for the master drive, and /dev/hdd for the slave drive.
[6] Familiarize yourself with /dev/hda and/or /dev/hdb, as the case may be. Note down the drive and/or partition(s) that you want to delete/wipe/format/reformat. Say you want to keep /dev/hda intact, but you want to wipe everything on /dev/hdb. Then on the "Device" tree, click on /dev/hdb. A visual representation of the drive should appear on the right side of your screen. This is similar to what you would get if you have ever format/reformat/defragment drives under Windows XP.
[7] Right click on any partition to get yourself familiar with the options for formatting, resizing or deleting partitions/drives.
[8] In your case, I assume that you want to delete all partitions on /dev/hda. In the "Device" tree, click on /dev/hda. Then right click on a partition and choose "Delete" to wipe it out. This won't actually wipe out the partition, yet, but just an indication that you want to wipe it. Do this for as many times as you have partitions. Once you're happy that all partitions have been marked for deletion, go to File -> Commit. Be cautious here; this will actually wipe out all partitions that you've marked for deletion.
[8] Once all partitions on /dev/hda have been wiped out, reboot your machine. If everything goes well, you should now be able to install/reinstall MS-Windows XP on /dev/hda.

You could try booting the Ubuntu CD and see if the disk partitioning step offers an option to take over the whole disk. Most installers will repartition and reformat for you, but I'm not familiar with Ubuntu. The installation instructions should tell you.
Alternatively, if you have to wipe it beforehand, then when you're in linux try 'df -k' or just 'mount'. These will list your mounted filesystems. If the partitions start with /dev/sda then your hard disk is /dev/sda and you can reformat the disk using 'fdisk /dev/sda'.
Most PCs will boot directly off a CD, but you may need to alter the BIOS settings to allow it and/or to make it try the CD before trying to boot from the hard disk.

I'm talking about Ubuntu 6.10 here, but I think Ubuntu 7.10 is similar. Once you've booted into the default desktop session, locate an icon in the top left of your screen called "Install". You may find this icon underneath another icon named "Examples". Run the "Install" icon and carefully follow the instructions.
First you'll be presented with the "Welcome screen", followed by the "Where are you?" screen. Then you'll get the "Keyboard layout" screen, which is followed by the "Who are you?" screens. After that, you should be presented with the "Prepare disk space" screen. This screen presents you with three radio buttons; here's what they look like on my MacBook
1. Erase entire disk: SCSI1 (0,1,0) (sda) - 120.0 GB ATA TOSHIBA MK1234GS 2. Use the largest continuous free space 3. Manually edit partition tableBut I think you can expect to see something similar to these three radio buttons. Radio button 1, the very top one, should allow you to automatically wipe out everything on your hard disk. Choose the top-most radio button and click "Forward". Carefully follow the instructions on the "Ready to install" screen. Once you're satisfied with your system's configurations, click "Install".

Unless you're root, you won't be able to use "fdisk" to change the HD via "fdisk". Try 'sudo fdisk /dev/hda'.

When I configure NIS client in Linux machines the client's roots are having exclusive access to the home directories by doing "su username "

It is on NIS.
In nis client root can do su - username

I don't think there is a way to stop that, other than not mounting the directories-that-shall-not-be-accessed.

That one of the major security problems if anybody besides trusted admins have root access anywhere with NFS shared files. You can switch off that root is allowed to su without password to a different user -- but then root can allow this again of course by changing the same config file.
The only way to give RESTRICTED root access (like apt-get ...) is setting up sudoers file so (specific) normal users may do CERTAIN things but definietly not everything (like sudo bash).
On the other hand with samba/cifs file it MIGHT be possible (not tested) to allow users to mount their particular part of home to a mount point they have access to (not all users to the same mountpoint) with authentification. Then local root might not be able to do so easily that much harm to other users. cifs is supposed to carry some unix attributes over samba shares, but I'm not quite sure yet what exactly and how to set this up with the proper fstab lines.

Hi All,
I'm trying to use Stunnel to create an encrypted tunnel into my LINUX box from another LINUX box and as much as I hate to admit it, I know relatively little about SSL implementation. I would like to set up connection from a relatively dumb test client application which requests of my test server to send out the contents of a file which I specify to it. This is done by firing up my server and having it listen to requests on specific port number which I have chosen, accept the connection and respond with the data over the socket. I have recently found Barry O'Donovan's article in the Linux Gazette which seems to specify how to set up Stunnel-4.XX to create an SSL aware server. That much seems reasonable. But my question is "How do I setup a similar scheme for the client?" I've found other articles, but they seem to be for older versions of Stunnel using flags that do not seem to apply to Stunnel-4.XX. So here I am with half the solution I need. Now what? Help!!!!
Many Thanks for serious replies,
Paul Harmon

I confess to not being a user of stunnel4 (even though I should be!). However, one need not actually do any "SSL-like" thing to connect to an SSL server which does not require clients to authenticate using SSL.
The option "client = yes" ought to do most of the work.
Next you need to decide on what port your stunnel will accept local connections (say this is 1234) and what port on the remote side you will connect (say this is 4321). You then put "local = 1234" and "connect = remotehost:4321".
Finally, you start stunnel and then point your non-SSL aware client to "127.0.0.1:1234".
To make the whole thing more SSL-like, there are two aspects:
1. Client verifies the server if you use
CAfile = certfile
where you replace certfile with the name of a file
containing the self-signed certificate of the CA of your
server certificate (or enough CA's to verify this server
sertificate).
2. Server uses SSL to authenticate the client if you use
key = keyfile
cert = pemfile
where you replace keyfile with the name of the file
containing your SSL private key and pemfile with the name
of a file containing the certificate for your key. This
certificate must be signed by a CA whose certificate is in
the CAfile of the server. (Chaining of certs is also
possible).
Hope this helps,

This is with the (default) setting "verify = default" which does not do SSL verification, but see below.
> To make the whole thing more SSL-like, there are two aspects:
In addition to the settings given in my earlier mail you need to set "verify=2" or "verify=3".

You've got it. In more detail:
Stunnel(client) does not provide the client protocol it merely creates an encrypted tunnel which the client can use to communicate with the server. Now your local network client needs to connect to some network port in order to take its part in the protocol. Normally this would be "remotehost:port". In this case we want to tunnel it so it is "localhost:4321" which speaks to stunnel. Then stunnel(client) encrypts this and sends it to the stunnel(server) at "remotehost:1234" which in turn then passes it to the actual server listening on some local port.
So, yes, the stunnel(client) is acting as a local server which proxies the remote service.
I hope this clarifies things. (I may have mixed up 1234 and 4321 so that the above description may be at odds with the configs I gave).

I have ubuntu 7.04 on a single user computer. New to ubuntu linux 0S & using the command line, trying to learn it. Need information on how to auto mount the platform device (floppy0) and the PC floppy drive. When I right click on floppy drive & click on mount, I get the error message, mount:/dev/fd0 is not a valid block device.

You may have a bad or unformatted floppy; that message often indicates one. If you believe that it's neither, try inserting it into the drive, then (without trying to mount it) check to see what it looks like to the system:
sudo file -s /dev/fd0

1. The very first Google hit on "remove Linux" is http://support.microsoft.com/kb/314458 , "How to Remove Linux and Install Windows XP". Article appears to be sufficient albeit grossly overcomplicated.
2. However, I would think it should suffice to just boot your MS-Windows XP installer from its CD or DVD or whatnot, and tell it to blow away whatever's on the target hard drive. I'm pretty sure that even XP can handle that extremely elementary installation task.
Basically, what you tried to do was boot the hard drive. As the old technical support joke goes, Don't Do That, Then.

If you're booting the MS-Windows XP installer CD/DVD, the installer program (Setup or whatnot) would (usually/often/always) hiccup if it finds that your master IDE HDD has a partition on it. Setup doesn't care what kind of partition, as long as there's a partition. Then you'd get the infamous BSOD, or your screen would just blank out.

I actually checked using an XP installation CD and the ThinkPad T42p test machine in front of me, which has a bunch of Linux swap and ext3 filesystems on it. No such problem seen.
I did not proceed to actually wipe the drive, as I have uses for those filesystems, as yet.
FWIW, in the general case, I'd just keep a live CD around, boot it, and "dd if=/dev/zero of=/dev/sdXX bs=512 count=1". Clean, fast, foolproof. But the "I want to install XP" querent wouldn't want to hear that, so I didn't bother to tell him.

When I said that Setup would hiccup, I have actually tried to boot the installer CD on a PC with two IDE HDDs and two IDE CD/DVD drives. The booting and installation processes didn't go smoothly, because /dev/hda wasn't a partition-free drive, meaning that there shouldn't be anything on it just like what you'd get when you purchase an IDE HDD. BTW, /dev/hdb wasn't connected to the motherboard when this was happening.
I then proceed to wipe everything on /dev/hda, and then run the installer CD again. This time, no BSOD and the installation went OK.

It works on my ThinkPad R40. But I'd need to download extra drivers to accelerate the GUI. I chose to install Slackware 12.0 instead.

You're right.

A "quick and dirty" way is to get yourself a copy of a Knoppix distribution. Perhaps from Knoppix 5.x onwards, maybe from 3.x onwards would also do the job. Here, I assume that you use Knoppix 5.0.1 or 5.1.1 CD/DVD distribution.
[1] Set up your BIOS to boot a CD/DVD drive first.
[2] Boot up the Knoppix live CD/DVD. This will take a while to load X and get you into KDE, a graphical session under Linux.
[3] Once KDE is ready to use, locate the "K" icon in the bottom-left corner of your screen. This is the menu for KDE, similar to the "Start" menu under Windows XP.
[4] Click on the K menu and locate "System". You need to be patient with live CD/DVD distributions, depending on your system's hardware specifications. Once the "System" menu pops up, click on a program called "QTParted". I think there are two icons for this tool within the "System" submenu:
1. QTParted (create, reorganize and remove partitions) 2. QTParted (QTParted)You can choose either of these two programs.
[5] I assume that you're using IDE HDD(s) and IDE CD/DVD drive(s). Once QTParted is up, you need to familiarize yourself with the "Device" tree on the left side of the program window. If you have two IDE HDDs, then your master hard drive will be /dev/hda (this is also the case if you have only one IDE HDD), and your slave drive will be /dev/hdb. Your IDE CD/DVD drive(s) will be /dev/hdc for the master drive, and /dev/hdd for the slave drive.
[6] Familiarize yourself with /dev/hda and/or /dev/hdb, as the case may be. Note down the drive and/or partition(s) that you want to delete/wipe/format/reformat. Say you want to keep /dev/hda intact, but you want to wipe everything on /dev/hdb. Then on the "Device" tree, click on /dev/hdb. A visual representation of the drive should appear on the right side of your screen. This is similar to what you would get if you have ever format/reformat/defragment drives under Windows XP.
[7] Right click on any partition to get yourself familiar with the options for formatting, resizing or deleting partitions/drives.
[8] In your case, I assume that you want to delete all partitions on /dev/hda. In the "Device" tree, click on /dev/hda. Then right click on a partition and choose "Delete" to wipe it out. This won't actually wipe out the partition, yet, but just an indication that you want to wipe it. Do this for as many times as you have partitions. Once you're happy that all partitions have been marked for deletion, go to File -> Commit. Be cautious here; this will actually wipe out all partitions that you've marked for deletion.
[8] Once all partitions on /dev/hda have been wiped out, reboot your machine. If everything goes well, you should now be able to install/reinstall MS-Windows XP on /dev/hda.

Again what the HTML. Stop it.
Yes you can run a java class file with cron.
java somefileAssumes you have $JAVA_HOME set correctly which you will need to do within the crontab file due to how cron clobbers the environment it runs under.

This is bad. This will continually run the specified program, not to mention potentially fill up /tmp very quickly if it contains any data.

Install the JRE from Sun, and not use the GNU stuff. My reply to you from before about JAVA_HOME also applies here.

This is also going to fail because java (sun java, I haven't tested gnu) does not allow a path to be specified like this only a java class name. you need to run a command like this
java -cp /opt/javafiles movefilesusing the 'classpath' switch to specify a path if the class file is in a directory that is not in your CLASSPATH environment variable.
>> but I got following error. >> >> Exception in thread "main" java.lang.NoClassDefFoundError: >> .opt.javafiles.Movefile >> at gnu.gcj.runtime.FirstThread.run() (/usr/lib/libgcj.so.5.0.0) >
This error translates as 'didn't find the file' since java has
helpfully searched your current directory and CLASSPATH directories for
a file called '.opt.javafiles.Movefile.class' . This behaviour must have
seemed a sensible idea to someone at sun

It means that you don't have CONFIG_X86_CPUID enabled in the kernel (that' s in the 'Processor type and features' section).
CONFIG_X86_CPUID: This device gives processes access to the x86 CPUID instruction to be executed on a specific processor. It is a character device with major 203 and minors 0 to 31 for /dev/cpu/0/cpuid to /dev/cpu/31/cpuid.If you want to use x86info, you'll also need to enable CONFIG_X86_MSR.
