Well i use an alias to mount a floppy added in ~/.bashrc

so when i type floppy on the shell the floppy is automatically mounted.

Not necessarily: he may be so busy rewriting parts of the kernel, and

I never noticed that before. But that raises the question, why do

Why do not users make backups? Those who used Windows before must realize
more than any the importance of backups when the system loses or messes up
their files. A user's accidently removing a file is just the same. I have had
Unix lose me (all but the first block of) a file once in 25 years, and Linux
has never lost me a file in over two years, but I remove one by mistake every
once in a while. Backups have saved me every time.

************************
Method of Software Protection
Description of invention:
The normal method of protecting software is shown in diagram1 and my method
which I
wish to patent is shown in diagram2. The software A that is to be protected is
shown
below as a box and it takes as input information B and outputs information C.
diagram1: Normal method of software protection
The input information B is provided by the customer. The output information C
is the
result the customer wants and is paying for. In order to make sure that the
customer is
lawfully using the software A, a license device D is used. This device can be
a software
code used as a key or it can be a physical device attached to the computer’s
serial or
parallel port.
My method:
My method is shown in diagram2. The software is no longer protected by the
license
device D. Instead it is supplied without any licenses and can be used by
anybody. Indeed
everybody who uses the software can simply make multiple copies and use as they
wish.
However, the output C of the program is no longer usable by the customer
because it is
now encrypted. In addition to C, the program outputs a smaller file D.
Alternately
another software (not shown) can generate D from C. D is a set of numbers or
characters
obtained from C in such a way that the probability of obtaining the same output
D from a
different customer’s copy of C is very small. This can be done (for example)
by simply
selecting the 5th, 27th, 63rd, 81st, 102nd, 174th and 237th characters in C to
create a
string of 7 characters as D. Alternately D can contain additional characters
that identify
how much of effort software A had to make in order to generate output C. For
example,
if the 8th character is an “M” it could mean that software A had to exert
“medium effort”.
If the 8th character is a “Z”, it means software A exerted “maximum
effort” to output C.
Now, D is sent to the software vendor E. The vendor E encrypts D and sends
back output
F to the customer, after the customer pays the required fee. For example the
output F
could be the RSA encryption of D using RSA numbers only known by the vendor.
diagram2: My method of software protection
Now, customer feeds the encrypted output C and the file F to a software G.
Software G
knows the RSA numbers because it was written by the vendor E. It also knows
the
encryption scheme used in software A because it was written by the vendor E.
It simply
checks the 5th, 27th, 63rd, 81st, 102nd, 174th and 237th characters in C,
encrypts them
using the same RSA numbers used by the vendor and if the result is F, then the
software
G knows that the customer has paid the required fee and so software G then
proceeds to
decrypt the output C into the output H. H is the output file that the customer
needs, and
the transaction is now complete. Alternately, G can be incorporated into A.
When the customer inputs a different input to software A, then the output C and
output D
will now be different, and so the customer again has to request the vendor to
generate a
new file F in order to decrypt the new output file C and so the software A is
well
protected.

You need to check lots of things. If stuff ends up in /var/spool/mqueue and
does not go out instantly, then sendmail tries once an hour to send it. If
your dial-up connection to the Internet is not up then, it waits another
hour, etc., until it can go out. (The 1-hour interval can be changed, but I
think that is the default).
If that is not the problem, you should make sure that sendmail is running
(run top, pstree, or something, to find out). If it is not, you may need to
adjust stuff in /etc/rc.d/rc?.d (if you are running Red Hat; I do not know
where to look for other distributions) and restart it in /etc/rc.d/init.d.

Subject: Slackware, Soundcards and kernel matters...
Date: Mon, 20 Nov 2000 13:43:32 GMT
Hi!
I was fiddling around with my Slackware 7.1 based Linux box,
so far upgraded with the 2.2.17 kernel and KDE 2.0 only when
I encountered something I couldn't soleve by looking at the
howto's. I know it's there, somewhere, but I can't find it...
The system won't let me use the sound card unless I'm root.
No mp3's, no system sounds, no nothing. It's OK, I'm used to
not having sound, but since root can use all this, why won't
it let my regular account do it?
I think it has to do with a file permission, but I'm stumped
as to which file and which permission. Can anyone help me out?
(Kernel is 2.2.17, compiled as a modular kernel, with the
emu10k1 module loaded at startup. I've not yet tried if it
works in GNOME, since I'd have to install that first.)
Next, the 2.4.0-test9 kernel. It looks good, it starts good -
but where oh where did my modules go? I can find the files,
but modprobe has turned blind. The /lib/modules/2.4.0-test9/
tree looks nothing like the old 2.2.x trees, so I wonder what
to do about this. I _want_ that ACPI support. I _need_ the USB
functions. RH had USB, which I liked very much, but wouldn't
compile anything. 2.4.x has all of it, but I can't load the
modules... Again, can anyone give me a hint?

As several people have pointed out, you should get a dialog box
asking where you want to put the file and giving a default.
This should be what you set in "Download Files To". But you
have to have permission to write in that directory in order to
save a file there. Either choose a directory like your home
directory where you have permission or change the permissions
on the default directory if you have root authority.

I believe disk druid is not available outside installation.
fdisk is not that hard to use, but cfdisk is a bit friendlier.

Subject: ufs rw filesystem driver?
Date: Mon, 20 Nov 2000 09:04:50 -0500
Hola,
I'm moving a drive from a FreeBSD system to a new install of Mandrake 7.2
(Server install - high security).
I've read on the FreeBSD website that linux > 2.1 kernel has rw support for
ufs filesystems. So I try the following.
# mount -t ufs -o ufstype=44bsd /dev/hdc1 /mntpoint
# touch /mntpoint/filename
touch: /mntpoint/filename: Read-only file system
# mount | grep mntpoint
/dev/hdc1 on /mntpoint type ufs (rw,ufstype=44bsd)
So it says in mount that it's rw, however when I try to write to it, I get
Read-only file system!
Am I missing something here, or am I doing something blatantly wrong? I've
tried adding rw to the options as well. Does Linux not really support rw of
ufs???
