Subject: Help with CD-R & CD-RW !
Date: Tue, 11 Jul 2000 15:57:55 GMT
Hi,
I have to admit that the man page for cdrecord is too big and
incomprehensible for me. Could someone walk me through the steps needed
to
1) create an audio cd image from a bunch of mp3 files (using mpg123 &
cdrecord?)
2) create a data cd image from a bunch of files
3) burn a cd image to a CD-R
4) same as (3) but with CD-RW
Extra questions:
Can I skip the the image creation using pipes or something?
Do I have to transform mp3 into wav first to feed it to cdrecord? (I
don't have to do it with windows software)
My CDRW gets mounted under /mnt/cdrom (/dev/cdrom, which is a link to
/dev/hdc). Do I need to use another "dev" for writing (as opposed to
reading)?
Thank you so much

Subject: extending video card driver functionality
Date: Tue, 11 Jul 2000 15:57:47 GMT
Does anyone know of references regarding
how to (programatically) get a video card that
supports hardware scaling to actually perform
the scaling when the driver provided in the
XFree86 distribution does not provide this
functionality? Ideally, the solution would
involve adding this functionality somehow while
maintaining the use of the (perhaps hacked) XFree86
server.
So far I have been able to find no relevant info
concerning this problem, and consequently, I would
greatly appreciate any type of info or pointers
anyone could provide.
Thanks

Unless you have two hard drives, you will probably need to partition
your hard drive first. If your drive is already partitioned, then you're
set -- put windows on one of the partitions, and linux on another.
You can probably do this in whichever order though I've only tried the
order {Windows, Linux}. If your drive isn't partitioned, you'll need
to use something like fips or partition magic to shrink the existing partition
(assuming you have something interesting on it) so that your linux install
can create a new one in the resulting empty space.
Short answer: I've tried windows first, then linux, and that worked fine.
Lilo is a program that writes some stuff to the part of your disk which
normally loads the operating system. So when you boot up your machine
it says "do you want linux or windows?" and you say, of course, "linux".

*sigh* Yes, I *know*. I have RTFM, you know. Have you? Ansi.sys is _not_
ISO (or ANSI!) C. I have not, and will not, have ansi.sys loaded; the
ISO C standard does not require me to. Therefore, ansi.sys escape codes
are not portable and off-topic. What's so hard to understand about that?

Some Linux distributions by default compile the SCSI CDROM support (sr)
into the kernel. Redhat 6.1 is one that does this. In that case, there
is is no sr_mod. Almost certainly the case here, so no loading is
required.

I'm afraid you missunderstood it. The ftpdaemons (am using wu) are
initiated as root (try opening an ftp connection from command prompt),
before you log-in, the process will be running as root, but as soon as
you log-in as a user, the ftpd will be suexeced to your username. You
can easily monitor the process with ps aux|grep ftpd and see how it
happens.
My problem is the ftpd is initiated as some xy username (not the
username trying to logon, but some xy user that is home asleep at the
time :)) and not as root as it should be, so he is not able to read
the /etc/ftp* files and the ftp* files shouldn't be worldreadable.
So... does anyone have an idea why is my ftpd initiated under a xy-
username and not under root?

No. It causes it to send plain-text passwords, which is the default for
a linux Samba setup. If you're worried about security, this is a *bad*
idea. If you don't have administrative powers on the linux box, then
it's your only hope.
If you have root access to the linux box, modify the /etc/smb.conf file
to enable encrypted passwords. Then create an smbpasswd file by running
/usr/bin/smbpasswd and add the user to it. (You can even have blank
passwords if you want.) You're done.

It should be able to, but as I said above, it's not a good idea for a
secure system.

Look in /etc/inetd.conf there should be a line like:
ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -l
-a
^^^^
Here is where it tells inetd what user to run the ftp deamon under.

I'm working on a very similar issue right now. My /dev/console is
missing but the /dev directory is there. Mine is an RH60 system so I'm
planning to boot from an emergency floppy and the install the dev*.rpm
file. If you're missing the entire /dev directory, you're gonna need a

I think it only converts to PCL3. But it's free, so you can keep your

The columns and rows within a workspace are also called viewports.
The difference that I have noticed is that the viewports are contiguous,
whereas workspaces are independent. One can use the mouse to drag a window
across the edge of a viewport, and move it into the adjacent viewport. One
can also use the middle mouse button to move windows from viewport to
viewport on the Gnome pager.

Do you have a loopback plug connected to the serial port so
that data that comes out the Tx Data pin gets sent back in the
Rx Data pin?
cat "zxcv" >/dev/ttyS0 # data goes out Tx Data pin
cat /dev/ttyS0 >asdf # capture data coming in Rx Data pin
Your other option is to use mknod to make /dev/ttyS0 the slave
port of a pty pair, and read your data from the master port of
the pair. This way you aren't using serial port hardware at
all.
