MPlayer will play the VCD file like usual, but with no sound. Just wait
until it finished. You'll get a file 'audiodump.wav' that you can convert to
MP3 by using the command:
$ lame -h audiodump.wav newfile.mp3
Switch -h is used to get high quality MP3 file, but bigger filesize.

Netkit
flavio ()
I just wanted to let you know about a nice project carried out at the Third
University of Rome, namely "Netkit".
In a few words, Netkit lets you build a virtual network in order to do all
the tests you would like to carry out, with special focus on learning how to
use routing protocols and stuff like that. This virtual network is realised
launching separate instances of Linux in different xterms - each being a
full-fledged Linux box! There are methods to connect those Linux boxes via
virtual Ethernets and also to communicate with them from the main host.
Netkit owes 90% of the stuff to UML, aka User Mode Linux, which is a project
to let the user launch a Linux Box inside Linux. But I think that they had
really an hard time to set up all the environment and create something
really usable for these network experiences. Moreover, their website
includes a lot of lectures about networking experiences using Netkit. To be
honest, when I prepared my exams I found a couple of broken examples but
everyone should be able to fix it or to... jump to the next example.
Given the fact that you're probably going to acquire tcpdump logs of the
experiences if you decide to give Netkit a try, I also suggest to download
and install Ethereal, which is a nice GUI to explore tcpdump sniffs.
You can find Netkit at [63]http://www.netkit.org, more on UML at
[64]http://user-mode-linux.sourceforge.net. Ethereal is, of course, at
[65]http://www.ethereal.com.
Bye, Flavio.

That's not a bug, that's a feature
Jim Dennis ([66]the LG Answer Guy)
Question by Gary Luker (gluker from southerndata.com)
I found an entry on google regarding a possible bug in bash. I have a script
that does the following.
#!/bin/sh
formatmonth=`date "+%m"` month="$(($formatmonth * 1))" formatday=`date
"+%e"` day="$(($formatday - 1))"
when this is run if the current month is 08 it gives me this error. value
too great for base (error token is "08")
have you found a fix for this? or know a workaround? thanks for any help!
Gary Luker: MCSE, MCSA, MCP, Linux+, SAIR/GNU Linux Pro
The arithmetic functions in bash (and C and some other programming
languages) treat numeric literals with a leading zero as if they are in
octal (base eight). Octal digits range from 0 to 7; therefore 08 is not a
valid octal number.
Using GNU date you can use formatmonth=`date "+%-m"` to supress the zero
padding of the month. That should take care of the problem. According the
date man page the %e value is already "blank padded" so it will never be
mis-interpreted as an octal number.

As our readers may recall, The Answer Gang ([68]tag@linuxgazette.net) is
really a mailing list where the regular subscribers get all queries and
linuxy bits sent through, but it accepts questions and comments from
anybody in the world. Of course this means spammers throughout the world
email us too... -- Heather
Hello gang,
Here is a lurker's 2c worth on weeding out list spam. With a default set of
rules, Spamassassin does a reasonable job of cleaning up my inbox. Recently
though an increasing amount of spam sent to the TAG list has been getting
past spamassassin. On a mailing list I am willing (more so than for personal
mail) to accept the occasional false positive. So I wanted to try running
all TAG emails through a stricter set of spam catching rules. Here is the
configuration I have tried for the last week or so and found the spam:ham
ratio greatly reduced.
A seperate spamassassin config file is used for TAG. From .procmailrc:
:0fw: spamassassin.lock
