FYI:
1) You means /proc/net/ip_fwchains?
2) You can simply move /sbin/ipfwadm to /sbin/ipfwadm.real, and
ipfwadm-wrapper will do this for you.

you dont read much do ya? Mp3s need to be converted (decompressed) to
Wavs before being put onto a CD IF you want them to be played thru
regular cd players. If you dont care if they cant be then go ahead and
leave them in mp3 format. You dont convert Wav files into ANYTHING.
That's the format audio has to be in for it to be played thru a cd
player. Wav IS the proper format. Each song has to be in its own
track. You put 10 songs on a cd, then cd will have 10 tracks. And an
audio cd has no filesystem so no mounting ( coudlnt do it anyway) is
needed to play a cd in Linux. To convert an mp3 to wav u have to get a
decoder program to decode the mp3 and decompress into a wav. Being a
Wav and in CDA format is the same thing, just for clarification.
and an audio cd isn't an audio cd until it has audio on it, before then
its just a cd. Only until you put some kind of information on it does
the CD become a specialized cd such as an audio cd, a data cd, etc. So
when u want to put mp3s on an audio cd, u should say u want to put them
onto a cd to create an audio cd. Just another hint on clarification.

I'm running kernel 2.2.7 and it has read-only support for NTFS partitions.
I can copy files from my NTFS drives while booted up into Linux. Support

You have to pass special parameters to the kernel to tell it u have more
than 64 megs of RAM. I forget the technical problem that causes this
but I can tell u the solution. In your lilo.conf file you have to add
teh line 'append "mem=128M"' . I believe that is the correct format.
Add that before the info that describes your partitions. If 128 doesnt
work u will have to try say 126 b/c if u tell linux it has more ram to
work with than u really have then it can stop booting like mine did. I
have 96 megs of RAM but in the boot sequence it shows 98***Kbytes but in
the lilo.conf file i had to put 96M so u should put 128M and see what
happens. And dont forget to run 'lilo' to put the new settings into
effect, then reboot. That should do it for ya.

Of course not. Corporation action does require profit
motives. It's more like prisoner's dilemma/social dilemma
situation where each individual (corporation) has no
rational motive to provide service, whereas cooperation

Well, I think it should have freed up a few of those buffers and caches
in order to allow me to run "free" for instance...
After going to 2.2.7, things seem to be okay - it gives me enough memory
to do things when I need to. I got about 3Mb into swap before reaching

Aha... cheers. The swapon(8) man page says that the priority given should
be between 0 and 32767, hence my confusion :)

They provide equivalent functionality (from the source level, at
least). GNU libc is actively maintained, is more portable between
machines, and has transparent support for things like NIS and Hesiod.
Linux libc (libc5) doesn't face the political challenges that GNU libc
has, but also hasn't seen a release for two years.
Most current distributions use some form of GNU libc. This includes
Debian 2.0 and later and Red Hat 5.0 and later. AFAIK Slackware is
the lone holdout for the Linux libc.

You should say which Linux distibution you are using!!!
I am using RedHat 5.2 and I've had the same kind of problem.
If the modem doesn't respond and your com-port (cua#) is set correctly?
Then it's sounds like your irq# is incorectly set in Linux.
First check your Irq# setting in Windows (Hope you know how)
Then in linux (I am assuming you are using RedHat 5.2) check The "rc.local"
File-settings (You must be "root")
First read the file : "less /etc/rc.d/rc.local"
Or
Use the command "setserial -a /dev/ttyS2" (or /dev/cua2)
If the irq# is not the same as in windows then you will have to change to
the same as the one in windows. (You can also find your modem's irq setting
in the modem's manual)
Editing the "rc.local" file in emacs is quite easy. you can put the full
"setserial command" in your "rc.local" file or just modify the irq#
If you can connect to your Isp but cant connect to the web the probobly
your DNS is incorect which you can get from your ISP.
Hope it works

No, that was FAT32 support. VFAT support was there years ago in my

The PATH variable specifies a list of directories that your shell uses
to find programs to run. If your shell is bash, zsh, or ksh -- type
"echo $SHELL" to find out which -- the PATH has the form
/path/to/directory1:/path/to/directory2:/path/to/directory3 (etc.)
You alter it by typing something like
$ PATH=$PATH:/path/to/another/directory
at the prompt, or do it "automatically" (upon each invocation) by
putting such a line (without prompt) in the appropriate startup
file in your home directory, which should have a suggestive name
like ".bashrc" or ".zshrc" ("rc" = "run commands" or something like
that). (Oh, files with names starting with "." are hidden by
default by the "ls" command.) Consult your shell's documentation
for further details.
(If your shell is csh or tcsh, the syntax is slightly different.
See its documentation, or change your shell.)

Unix files remain there for as long as they are open by any process for
reading or writing. If you remove the file you just remove it's name
from the
directory but the file itself is not removed until it is not referenced
by
any process. This is a useful feature. A program can create a temporary
file
and immediately remove it, but keepa handle to the file. Then use the
file
for readin/writing or even inherit the handle to other program. The file
is
actually deleted only when the last reference to it is closed.
You did not have to unmount. Terminating the program that had the file
open
was enough to actually delete it. Since the file is open by your X
session, logging out would be enough.
One easier way to regain that space would be not to remove the file but
to
empty it by eg.:
cat /dev/null > ~/.xsession-errors
Off course, that would not work if you already tried to remove that
file.

They are both standard c libraries. glibc (variously glibc2 or libc6) is
the GNU C Library, version 2, or the 6th linux c library. Libc (variously
libc5) is the 5th linux c library. glibc supercedes libc5, fixing some
bugs and linux-specific behaviour. It also brings all versions of linux
onto the same C library; non-intel versions have consistently used glibc
rather than attempting to port libc5 to whichever platform.
Ongoing linux devel is almost exclusively oriented to developing with
glibc rather than libc5; libc5 development is more or less halted (I
believe that the last bugfix has been released and the team disbanded and
moved on), although you can always pick up sources and continue.

"glibc" is a particular Linux libc. A "libc" is a "C library",
a collection of useful functions collected for the convenience
of programmers. These functions do such things as manage memory,
manipulate strings, perform sorting, calculate higher mathematical
functions, ask for services from the underlying operating system,
and do input and output. Every nontrivial program will use some
of these functions.
On Linux (like all modern unixes), the libc is a shared dynamic
library. "Dynamic" means that these functions need not be copied
into each executable program's binary file, but rather are loaded
from the library at run time. "Shared" means that things are
arranged so that when the same functions are needed by more than
one program, only one copy need be loaded into memory.
The Linux system has gone through several different libc's.
The current generation is called "libc6", "glibc" (for "GNU libc"),
or "glibc2", and is available in either 2.0.x or 2.1.x flavors.
Many programs and systems still use the preceding generation,
known as "libc5", "libc" (as opposed to "glibc"), or occasionally
"glibc1" (upon which it was based).

I believe that your code should look more like...
#include <stdlib.h>
main() /* implicit int */
{
long int x; /* you had double x; */
char state[8];
initstate(6,state, sizeof state); /* state is an array */
setstate(state); /* that's modifyed by initstate/setstate */
x = random(); /* random() returns long int */
printf("%.15ld/n", x); /* format corrected for long int */
return 0; /* always return completioncode to os */
/* above could have been exit(0); */
}
