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.

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

compressed issues of LG

Minh Nguyen [nguyenminh2 at gmail.com]

Fri, 2 Nov 2007 14:13:10 +1100

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.gz
IMHO, providing a bzip2 compressed format of LG issues would save some download time.

How do I reformat an Ubuntu installation?

Derry [fajd at tpg.com.au]

Thu, 29 Nov 2007 23:05:29 +1100

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.

NIS client root privilege

Smile Maker [britto_can at yahoo.com]

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

Is there anyway to prevent that.

Thanks & regards, Britto

Some stunnel questions (hopefully not too dumb)

Harmon, Paul [paul.harmon at nscorp.com]

Thu, 29 Nov 2007 15:44:51 -0500

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

It means that you don't have CONFIG_X86_CPUID enabled in the kernel (that' s in the 'Processor type and features' section).

  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  
If you want to use x86info, you'll also need to enable CONFIG_X86_MSR.
