How widespread is the "chkconfig" utility? I've got a system
admin utility and one of its functions manipulates symlinks in
/etc/rc.d/* to enable/disable a particular service.
If chkconfig is available in most distro's I'll probably change
it it to try using chkconfig first, and if that can't be found
manipulate the symlinks directly.

You're not killing a script, you're killing Perl. Or trying to.
That is, if I understand what you're trying to do. Maybe I don't.

Subject: Can't boot from SCSI if IDE is on
Date: 01 Jun 2001 23:16:59 +0200
I have a computer where the IDE drive has gone south. But the SCSI
drive is still okay. So I copied data from the IDE drive and
installed a new Debian potato on the SCSI drive. Installed a kernel,
ran Lilo. Lilo warned me that this (/dev/sda) is not the first disk.
I boot the machine, get `L 10 10 10 10...' or similar (might be `LI'
rather than `L' and might be `10' rather than `10 ') where the 10
keeps repeating until it fills the whole screen.
Booting from a floppy works. And also, I go into the BIOS setup, turn
off everything it knows about IDE, boot again (from sda): works.
So, how can I boot the machine from sda without losing access to the
IDE drive and the ATAPI CD-ROM in it?

This might be an unbelievably stupid question, but is there any danger
that I could lock myself out of my server if I rebuild OpenSSL over an
ssh connection?
I'm missing a few libraries and have to tweak a couple of things. Since
OpenSSL is (I think) actively involved in maintaining my connection,
could I hose myself by rebuilding it over itself? I'm not entirely
clear on how all of the parts work together.

He may be using a 64-bit, 66 MHz PCI slot. On a 'regular' PCI slot, 90
MB/sec is about where you can expect sustained transfers to be, on a
64/66, it's about four times that much.

Read the lilo docs for more info.
You'll have to play with the disk designators (0x80, 0x81, etc) in your
lilo.conf.

Does the floppy drive activity light even come on? If not, check the power
and data connections. Disconnect both, then reconnect. This will usually
clean accumulated crud from the contacts. Make sure that your floppy drive
is connected to the LAST connector on the cable.

I think that's basically it. In the case of Gnome, I think the major
packages have the same names, but some won't (libgtk1.1 vs libgtk1.2
and things). In those cases, apt-get upgrade will tell you about the
new packages that it's intending to get (like libgtk1.2).

stable. And it won't get everything---just what it thinks are
appropriate for upgrading your current installation. It's really
intended to be a more automated "apt-get upgrade".

It's the latter. "apt-get dist-upgrade" with unstable is fine.
As others have said, you probably want to do "apt-get install
task-gnome-desktop" and things like that.

Sure, it's possible, however you need a terminal

Hi,
I would like to setup a linux box on a 486 in order to share my Internet

Right now, I'm running an NT4 Server SP6 but I'd like to try Linux. I

Reply-To: [EMAIL PROTECTED]
After I had upgraded the kernel on Mandrake 7.2 I had to compile Alsa
package for my SBlive - for obvious reasons the old sound modules stopped
working.
First I tried the stable alsa packages (0.5.11) - they compiled and
installed quite well but unfortunately the bass and treble sliders were
gone.
So i ventured into the beta stuff (0.9.0beta4), no probs with
compile/install/modprobe etc. and watched in awe how the sliders appeared
in aumix... Unfortunately setting the bass/treble makes no difference, so
now I'm stuck with a couple of useless sliders I can toy with when I'm
bored. On top of that, as one might expect, 0.9.0beta4 isn't that stable
and crashes some software...
Anyway I went back to 0.5.11.
Has anyone had more luck with bass/treble in Alsa? If so, how did you do
it? What version did you use, etc?
The kernel is 2.4.4. Here comes the modules.conf:
alias char-major-116 snd-card-emu10k1
alias char-major-14 soundcore
alias snd-card-0 snd-card-emu10k1
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss

Set your system up with 2 network cards. Connect one to your ISP and the
other to your hub. Configure redhat with those 2 network cards. The
LAN-side needs a IP adres in the same "neighboorhood" as your other PC's.
Most common used is 192.168.1.XXX . Give it 192.168.1.254 or so. Than you
set up a firewall rule and enable ip forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward
ipchains -I forward -s 192.168.1.0/24 -j MASQ
OR:
iptables -t nat -A POSTROUTING -j MASQUERADE
I hope you got a somewhat recent distribution with at least a 2.2.x kernel.
I don't know the firewall-thingy older than this..
If your connected on an other way than via a network connection, remove one
network card and place there the device you realy need. An ISDN card or so.
Because I don't know what you use I can't explain the ISP part, but your
main question is answerd, I guess...
