[clug] More in the list of things that someone should have told me long ago.


I'm tired after sleuthing the meanings of bits of your code. So I'd 
appreciate in future plain-English explanation as well.

[clug] Full Circle

Issue #5 described the features of some Ubuntu releases. Also there was 
a review of a fork with a different interface.

Operating systems were compared.

Corporate news was of a project switching to Linux, as well as Linux 
out-competing other operating systems!

And an article described a presentation at an educational conference.

There were reviews of virtualiser and security application programs.

Page layout layers were explained.

Construction and strategy games were reviewed. As was a Wine Web site.

Articles described users:
     * transitioning to Ubuntu;
     * making suggestions;
     * asking questions; and
     * showing off a desktop and a PC setup.

Finally listed were bug-reporting and article-writing guidelines.

[clug] A Question About Password Handling and Authentication Mechanisms

I've been meaning to look into/ask if there exists a challenge-response
mechanism for passwords where the password doesn't have to be stored in
plain text or in a recoverable form, ie it can be stored using a
cryptographic hash. In fact, no where is the password stored or
transmitted over a channel in a recoverable form. Does anyone know of
such a beast?

I image it would operate something like this:

Say you have a password in plain text, password. It is then stored on
the server hashed, Hserver(password). Upon connection from a client a
challenge is sent to the client and using the plain text password
entered by the user the client carries out a one way calculation, call
this hash Hclient(password, challenge) which is then sent to the server
for verification. To do this the server performance another calculation
on the hashed password, Verifier(stored_password, challenge), and
compares it to the client supplied hash. In other words,

1)  Server stores password
  stored_password = Hserver(password)

2) Client connects.

3) Server send challenge to client, challenge.

4) Client calculates response to challenge with a one-way function
  response = Hclient(password, challenge)

5) Client sends response to server

[clug] using 'dd' in a pipeline

I’ve been looking at deliberate MD5 collisions and went to write a simple script based on ‘dd’, only
to fall flat on my face - detecting ‘end of file’ from STDIN.

‘dd’ doesn’t consider EOF as an error and returns “success”.

I could use dd’s “iseek”, but that ties me to named files in the file system :(
I’d prefer to use a pipeline - current script below, but it requires I first know the size of the file,
exactly the same issue as ‘iseek’.

One option is to catch the output of ‘dd’ in a temporary file, then test for its size, ending when the temp
file is zero length.

I tried using the bash ‘read’ with "-n 0”, but that reads an entire line [not good for a binary file]
‘IFS=“” read -r -n 1’ runs, but consumes a byte of the input and discards binary ‘\0’ bytes :(

The stat() and read() system calls either don’t report EOF, or return zero-length at EOF.

I could test if a program that does a read() of zero-length, then uses ‘select’ with a short timeout,
would reliably detect EOF on STDIN if it was a pipe or file.
It doesn’t seem reliable & portable to me, but it may be.

ioctl() and fcntl() didn’t seem to have

Anyone got ideas that I can use in a shell script? I’d prefer not to have to write code :)
There may already be extended versions of ‘dd’ that do this (haven’t checked these: dc3dd dcfldd
dd_rescue ddd)

Or suggestion on existing tools or how to implement a simple test for EOF on STDIN (pipe or file) in PERL, PHP
or other scripting languages.

[clug] Full Circle

Issue three got excited about 3D representation eye candy.

And there were articles on desktop layout, scrawling notes, desktop 
publishing, photography, music, multimedia encoders and video tutorials.

Users described their PC, desktop, and Ubuntu experience.

An Apple notebook was praised. And dual boot was discussed.

There was an exposition on Xubuntu. And a whine about American software

[clug] Next meeting and more

Hi all,

I've decided to step down from running the CLUG and PSIG.

I've been doing this job for many years now, and it's been increasingly
difficult for me to do well.  In part this is just because my focus has
changed, but mostly it's just because I've been doing it now for long enough
that the continual struggle to get another speaker or to organise a
discussion topic when we don't have one has made me tired and
unenthusiastic.  And CLUG deserves better than that.

So if you're interested in seeing CLUG meetings continue, in any form,
please come along to the meeting this Thursday to discuss what happens next.

Hope this helps,
