You guys have got me all wrong.
I love bash. I am a bashophile.
I just want to know if
Linux + /bin/sh = /bin/bash
I've written some init scripts to run
an application as a service on linux, which I posted
to a developpers list. Some have questioned the fact
that i used bash syntax for the script which has the
shebang #!/bin/sh, which to old unix hands means plain
vanilla Bourne, and there's stuff you do with Bash that
doesn't work on ol' Bourne.
I want to claim that on Linux /bin/sh is Bash by default.
Am I wrong?
Cheers

Run fewer programs? Changing kernels probably won't affect memory
usage. Most of those probably aren't running *simultaneously* unless
your server is very heavily used, in which case you need a better
server. How is swapping set up?

Quite true. It can't. The process won't be scheduled, and it doesn't
have control now, and it won't be woken up by an interrupt either.

You might improve the situation by killing the parent of the process
and thus getting it inherited by init. Init has magic powers.

Sorry, I'm sure this is what you mean, but if you type in "ping tornado"
from tornado, it successfully resolves that to 127.0.0.1?
You also didn't mention whether you restarted Gnome and X (though I
suspect you gave it a shot).

I don't really have any idea. After a short time? As you probably
know, most important intialisation scripts are run right at the start.
It might be related though. I guess you could give the whole thing a
reboot - even I do that when I'm really frustrated by a problem! But
don't expect your problem will vanish in Windows-esque style just
because you've restarted your machine!
Oh hold on, you said in an earlier post that you restarted xinetd. Is
there a init script called network (Mandrake is Redhat based, right?)?
If there is, you need to do a ./network restart (or equivalently I think
reload) to apply changes with your network settings.
Go on, see if that works!

In addition to the command line utilities mentioned below, there are also
commercial offerings from Arkeia, and BRU. Both are pretty well respected
entities AFAIK, but perhaps overkill for a small LAN. But if you are used
to a gui tool on a Mac, perhaps they would be worth it to you.

Give it a couple weeks. SuSE is kinda protective about letting their boxed
version sell a bit before letting you download the free version. May be as
much as three or four weeks after the boxed set finally hits the racks here
in the US (w/i the next week, from what I hear)

When you minimize an application it goes to the Iconbox. Another click
on the Icon and the application is restored. I guess it's something like
a taskbar. This screenshot shows the Enlightenment default desktop with
the Iconbox in the lower right, the virtual desktops in the lower left.

I do not know about the part of bearing stress. The spin up phase
normally puts far more stress on the bearings than continuous
running. It the only thing that mattered was bearing life, I would
prefer that my CD-ROM drive just left the disk spinning as long as
the disk were in the drive, or preferable, as long as the OS had the
drive mounted somewhere on the file system. But i use my CD-ROM
drive so seldom that it scarcely matters.

I tried that. I killed the the bash, and the su (I needed to run rpm
as root) so that init was then the immediate parent. init did not
seem to be able to get rid of it either. I guess the thing to do
would be to put a gizmo on the SCSI data bus that pretended to be
the right disk drive (I know which one it would have been, since the
.rpm file, the rpm database, and the root file system where the
vixie.cron stuff would go are all on the same drive) and generated
another hardware interrupt would probably work.
When I designed a hardware system (the one for which I wrote the OS)
in the distant past it would have been a simple matter. It was
possible to send output pulses to any of 16 "devices". These devices
were wired to a plugboard so the pulses could be sent wherever the
plugboard wires were connected. 5 of them were attached to the
interrupt request lines on the machine so that hardware device
interrupts could be simulated exactly. All the device drivers were
written so that spurious interrupts could cause no harm. (Details
omitted.) So all I would need to do is write a program that issued
such a pulse and it would wake up the device driver and this would
all let go. But my present hardware is not set up that way. Too much
trouble, and it should not be unnecessary. Since I do not hear of
this happening to others, I doubt it is a bug in the Linux kernel.
Likewise, I cannot imagine it to be a bug in the rpm program itself
(while it might have bugs of its own, I do not see how it could get
itself stuck in STATUS = D unless perhaps it tried to use a
non-existant device, and I do not see how it would get such a device
open in the first place).
The only other time this seems to happen is when I use my DDS-2 tape
drive. It is on a SCSI controller as well, but a different one.
I.e., my 2 hard drives are on an Ultra-2 SCSI controller and the
tape drive is on a narrow SCSI controller. So if there is a bug in
one of the controllers, it should not affect the other one, or so I
would assume.

If you really do need your script to be a bash script then why not simply
start the file with #!/bin/bash and be done with it?
If it's a bash script why wouldn't you want to say so?

I found it, but I hated it, and even had trouble getting rid of it.
When I created it, my taskbar said I had one, but I could not see it
(it was beneath another window on a different "panel" of my display.
Furthermore, when I clicked on the icon that gets me another xterm,
the xterm was in an awkward part of the screen and had no borders,
so I could not move it or kill it. I put the mouse in the middle of
the window and typed Control-D, but it did not appear to notice it.
I clicked on the Iconbox icon on the task bar and selected first
close, and then nuke and neither did anything. None of the options
included "Revmove from taskbar", so I logged out of my session and
came back in (restarting X Window System, and GNOME/Enlightenment).
I astutely did not check the "Save current setup" box. Then it was
gone and all is well. I do not think I want that feature on my
system. The panel (taskbar) seems to do enough for my needs.
Once or twice, in the bad old days, I deleted the panel (taskbar).
That was a royal pain because whenever I clicked whatever it was to
create a new one, it advised me that the new one would be only
temporary, and that was true. I was lucky to figure out how to fix
it.

Actually, the non-rewinding device would be /dev/nst0.
I have both on my machine:
valinux:jdbeyer[~]$ ls -l /dev/*st0
crw-rw---- 1 root db2iadm1 9, 128 May 5 1998 /dev/nst0
crw-rw---- 1 root db2iadm1 9, 0 May 5 1998 /dev/st0
valinux:jdbeyer[~]$
They came with the distribution I got from V.A.Linux Systems; I did
not need to make those nodes.
/dev/rst0 and /dev/nrst0 would be for those doing raw-io to the
devices. I do not know if Linux supports raw devices for tape or
not, nor whether there would be any benefit to using them for backup
purposes anyway.
As an aside, it is my understanding that Linux kernels from 2.4.*
series do support raw IO to disk drives in order to make
implementation of database management systems run more efficiently,
to ensure that journalling (related to commit and rollback of
transactions), and backup and recovery of systems that cannot be
stopped for doing backups, can run in a logically correct way.

Well, it sounds like you are masquerading ICMP OK.

It sounds like your outbound masquerading is working for TCP, but inbound is
not set up correctly for all ports. FTP use port 21 for the control connection
where you issue commands, but uses port 20 for the data connection where the
responses come back.

We probably need some more information if this doesn't help you. What kernel
version are you using? Are you using ipfwadm, ipchains, or iptables to set up
your masquerading? Can you attach a copy of the script you use to set up the
masquerading or if done manually, attach the output the ipchains or iptables
display of your tables. I can't remember the ipchains command to list the
current rules, but for iptables you can use iptables -L > /tmp/diags and then
append your ifconfig to it with ifconfig >> /tmp/diags so we can see how it is
set up.

Either get a program like PartitionMagic (Easy to use, but not for free) or
use
a program like GNU's parted (Which contains sufficient documentation)
Both can repartition your HDD non-destructively.
But you should still back-up any important data before you start, just to
be on the safe side.

Hello,
Can anyone tell me if it is possible to change the sequence of the rc.d
scripts at bootup? So the sequence of the scripts like this: Sxxxxxx
