Hi,
This is the first time that I tweak the kernel, therefore I have a
lot of questions, after over 10 hours of frustration experiences.
The task I want to do is rather simple -- adding the sound blaster
16 to my debian. But this "simple" task has gave me a lot of
trouble. To keep the long story short, here are my current problems:
I upgraded my kernel from 2.0.36 to 2.2.18pre21-idepci, had problems
building my Alsa so I upgrade to 2.2.19-idepci again, using the
dselect. But the wired things are:
- After reboot, I got a lots of depmod error, saying can't create
/lib/modules/2.2.19/modules.dep. Why it is not look into the
/lib/modules/2.2.19-idepci/ directory?
The seems a serious problem to me because last time, I build my alsa
in 2.2.18pre21-idepci environment with 2.2.18pre21-ide header files
but the results can't work with the 2.2.18pre21-idepci kernel. (why?)
- Also, modprobe is looking for the /lib/modules/2.2.19/, not the
/lib/modules/2.2.19-idepci/. How can I fix it?
- Beside, when compiling Alsa, the configure said:
checking for kernel version... 2.2.18pre21
how could I tell the it that my linux is 2.2.19-idepci now?
(I did the configure from clean dir)
- even after I've 'make; make install' the alsa drivers, when I do
modprobe -v snd-card-sb16, I still get an error:
modprobe: Can't locate module snd-card-sb16
why is that and how can I fix it?
Thanks a lot for your help. You can see that I'm really stuck
here. Beside, after upgrading my Debian, I no longer have network
connection at start up any more. I have to configure my eth0 by hand
to get it going... I really hope that I can get out of this trouble
soon. thanks.

And this means nothing, because setuid is ignored on scripts.

AFAIK, it's controlled via the menu Edit;Preferences
[not sure pure text attachments will respond though]
Version of Netscape you're using may invalidate my hint; look elsewhere in
the menus.

Read a little more about RAID before you implement it. If you have a
hardware RAID controller, the controller will initialize the RAID, and
all data will be striped across all disks, along with extra parity
information. /dev/sd[abc] will no longer exist; there will be only
/dev/sda, and it will appear as one 36G drive.
If you're doing software RAID, you will use "mkraid" to create the array
over /dev/sd[abc]. Data will still be striped across all 3 disks, but
you will access /dev/md0 as one big 36G drive.

The MBR will be striped across all 3 disks, with parity. Booting from a
software RAID-5 might be tricky, check the HOWTOs over at
http://linuxdoc.org/HOWTO/ for more info. (Can't help much, got some
RAID-5 and RAID-1 systems, but they're all done in hardware...)

no great expert on this but i think it's the PROGRAM which has to be suid

I don't claim to be an expert on 'net standards by any stretch of
the imagination, but aren't all news postings supposed to be wrapped to 76

Date: Thu, 24 May 2001 23:21:36 -0400
[Orig. post on 18 May, reposted due to no responses]
I'm hoping someone has seen this before and knows what to do; I
haven't been able to figure it out over the last few days.
I've got a Mandrake 7.2 system, with some updates but relatively
clean. Somehow I've managed to mess things up, probably in the process of
trying to put Xchat in. Now, all apps that use GNOME start up invisibly --
they display no windows, but show up as "Sleeping" in a process list. This
happens for apps that use GNOME libraries, such an GnuCash, Xchat, gnapster;
apps that use GTK but not GNOME (Xdownloader, RPMdrake) run just fine. I
normally use KDE as my desktop, and all of those apps also work ok.
Here are some packages which seem to be applicable:
gnome-core-1.2.1-40mdk
gnome-libs-1.2.4-8mdk [also -devel, same revision]
I have tried examining, changing, removing, config files in ~/.gnome,
to no effect. Xchat, gnapster, and Pan are new installations, but I've been
using the same GnuCash for a couple of months, and now it doesn't work
either. Even the GNOME panel doesn't show up.
I have searched the Web and Usenet before posting here; obviously I
did not turn up anything useful. :( Anyone got some clues I can borrow? ;)
*** Additional, 24 May: Have tried removing and re-installing gnome-core and
gnome-libs, no effect. Also moved ~/.gnome, ~/.gnome-private, ~/.sawfish, no
effect. GNOME apps behave the same whether I'm logged in as root or a normal
user. They are the same if I'm using KDE or Enlightenment -- only show up in
process list, not on X display. ***

...and remember that SUID shell scripts are *NOT* allowed. The kernel
will allow you to execute a SUID shell script, but it will not set the
UID. Security reasons, this has been discussed to death, search this NG
for the full explanation.
If you really need to have a shell script execute as root, and have
users other than root be able to execute this script, you need a wrapper
that's been chowned to root and chmodded SUID around the script.
Something like so:
#include<stdio.h>
#include<unistd.h>
int main(int argc, char **argv, char **envp)
{
setuid(0);
execve("/path/to/script", argv, envp);
return 0;
}

Subject: permanent mail server question
Date: Thu, 24 May 2001 23:40:45 -0400
Could anyone direct me in this project. I am a junior Linux network admin
and was asked to put up a permanent mail server on the net.
We are actually using the services of Netnation.ca for our POP accounts and
would like to have OUR OWN mail server. Totally independant. Internal
clients would
connect to that server with Outlook Express for the most part. It also has
to be available from the internet as well. I was planning to use
phpgroupware for outside
access (www.phpgroupware.org)
I need a little guidance as to what to do. I will be using Mandrake 8.0. Are
there any good howto pages out there that could tell me everything that
needs to be done? Like what to do in what order? How can I allow access from
the
inside, but not from the outside? (see outside remark earlier)
I have found many howto's (especially the ones on MUO) that explain how to
do
this with an external POP provider, like ISP's. I really require a full
blown mail system. A complete replacement to Exchange.
Any help would be appreciated.
Best regards
Marco
