Hi, I have just reinstalled Slackware 7.1, everything is mostly ok,
but my sound blaster 16 card only works as root. There must be some
simple way to fix it ..... please help guys.
I am using 2.2.18 kernel.
Thanks very much.

The easiest way is to prepend the "current directory" indicator, i.e. "rm
./--atime-preserve".
BTW: On my system, "man rm" says in the first page how to remove files
starting in a dash (the author shows how to remove a file called "-f" with
either "rm -- -f" or "rm ./-f"). The lesson here should be: RTFM ("Read the
Fine Manual" -- Yeah, I know, some people have quite another definition of
the F).

Date: Sat, 24 Feb 2001 17:52:29 +0800
I'm working on a socket programming project: requires me to find out the
time-stamp when i send and receive the same data i sent to the echo server.
Is there any way i can out the actual DATA into a file along with its
time-stamps ??
I can use Ethereal to see the DATA but however, there is no time-stamp along
with the DATA.
Do you know the command for tcpdump to show the DATA along with the
time-stamp??

I plan on implementing software RAID1 on my new linux box with twin scsi
barracudas. Can 2.2.18 do it well or should I be looking at 2.4.2 instead? I
need it to work well the first time with no problems.
Can anyone suggest anything? What should I know or do? Is the RAID code in
2.2.18 just as good as it is in 2.4.2?

just get the modems working. No special configuration is needed as far
as the modems go. Beyond that you will need to implement ip masquerading
on the 'linux' machine and a proxy server on the 'Windows' machine so
that one can pass thru the other in order to access your outside
network.
you will need to assign IP addresses to both computers in both operating
systems.
Obvioulsy your work is doubled.

download the kernel source from ftp://ftp.kernel.org
use tar zxvf kernel.2.4.2.tar.gz in /usr/src to decompress it
remember to rm the alreayd existing link named 'linux' as when u
decompress the above it will create a new directory called linux. you
will want to rename this to something like linux.2.4.1 and recreate your
'linux' link to this directory
then do a 'make xconfig' while in an xterm
read the README that comes with the source. it will explain theprocess

What happens if you boot with KBD, then pull it out?
Is this acceptable, or do you require unattended reboot.

I found out on www.linux-usb.org that USB-storage is not supported in
the 2.2 line of kernels.

Subject: trouble compiling gnome-utils
Date: Sat, 24 Feb 2001 06:22:47 -0500
Hi,
I am trying to set up a linux system completely from scratch, i.e.
compile all the source myself. Following the LFS (linux from scratch)
instructions compiling the basic system was no problem. However, trying
to compile gnome is a different story. When I try to compile gnome-utils
I get the following link error.
gcc -g -o gfloppy main.o gfloppy.o progress.o fdformat.o badblocks.o
-rdynamic -L/usr/lib -L/usr/X11R6/lib -rdynamic -lgnomeui -lart_lgpl

/usr/lib/libxml.so: undefined reference to `gzclose'
/usr/lib/libxml.so: undefined reference to `gzwrite'
collect2: ld returned 1 exit status
when I look at the symbl table in lixml.so these are not defined (the
linker is not lieing to me). However, when I check for the symbols in
libxml.so on my working setup they are undefined as well. Thus I do not
understand how this works, or maybe it doesn't and I just don't know
it.
The question now is how do I get the symbols defined in libxml.so?
A search on google for any of these always points me to PHP, which
appears odd to me that one has to have web server tools installed to
build GNOME floppy support.
Any help is appreciated.
Thanks,
Robert

Redhat ships three packages related to vim. Install all of them and
start it with the "vim" command instead of the "vi" command.

You may either want to look at tcpdump dumping its contents into a binary file
and then getting tcpdump to play back the file for you. I know that tcpdump
is capable of time stamping everything for you including going down to the
hundredth of a second.
Another package which you may be interested in is called SNORT. It is capable
of listening to traffic on the network as well as allowing you to apply
filters to the traffic. I also think from memory (although I could be wrong)
that SNORT is capable of time stamping everything for you as well.
SNORT allows you to actually see all the packets being sent as they fly past
your network card.
See ya

/usr/local/bin/eagle seems to be a script (wrapper) and it seems to try to
access another script/program/file/directory which is simply not there. I
guess you have to kind of "debug" the script to find out what's missing.

Isn't this part of the RedHat Network thing?
One of the first things I do after any new install is go through the
list of daemons that automagically start and trim it down.
Same for network services.
At least RH left it in the list, so it is easy turnoffable unlike many of
M$ crap. (anyone know how to easiy remove the "use netbios over
tcpip" thing?)
Given the number of updates that are needed to bring a RH 7.0 install
up to snuff, having something like that run for a day or so isn't a bad
idea. (although a post install script should run once to see what's new,
and it should pop up and tell you that a) it's running, b) it would be a
VERY good idea to check)

Hello,
you could just cat them of /etc/passwd, asuming they are UNIX users on your

In 2.2.x the right way to do this is:
{
int error;
lock_kernel();
error = do_mkdir(tmp,mode);
unlock_kernel();
}
You perhaps also need to save the filesystem user ID and change it to
something else and restore it afterwards. It is a problem, that
do_mkdir() is a static inline function, I suggest that you simply copy
the entire function to your module.
In 2.4.x things have changed, sys_mkdir is now twice as complicated as
it used to be. do_mkdir has been replaced by vfs_mkdir, which does not
do exactly the same. I don't know exactly how your code should look in
2.4.x, but I think more or less you should copy sys_mkdir() except
from the part that copy the name from userspace to kernelspace and
releases it again.
The good news is that in 2.4.x vfs_mkdir() is exported.
