Hi all!
I know you can use modprobe and insmod to load modules. But is there a
command I can use to see if a module is loaded?
TIA,

Let's see. I can buy a cheap PC clone on which I can run Linux -- in a
networked environment so I don't even need anything more than the OS
itself -- for about $600US. At even a bargain basement (costing) rate of
$50US hour, that's only 12 hours of programmer time. Considering the
complexity of Linux, you'd have to expend thousands of hours to get
something that might -- just might -- provide a moderately faithful
emulation of exactly one version of Linux. Just one version! To get three
versions, you'd probably have to double that. And who's going to do the
program maintenance every time a new kernel version comes out? You?
Probably not. You wouldn't have enough time to understand all of the
differences from the last version in time to get it coded before you'd have
to start working on the next new kernel version.
OTOH, If I'm really paranoid, I can get removable shells for my HD's so I
can remove all but one OS drive every time I'm ready to test a new "feature"
of my hardware. Perhaps for an investment of $1000US I can create a totally
"safe" computer with two HDs, one of which is used only to restore the OS on
the other in the case of a total wipeout. And that's buying new hardware.
I can probably scrounge up enough hardware in my basement to create one of
these machines for under $100US.
While it might be a nice thing to have, it's totally economically
infeasible. Maybe it might make sense for a stable OS like Windows ;-) but
not for something that's changing as rapidly as Linux.

I was trying to shutdown my computer remotely. I typed the shutdown -nr 1
command and the system shutdown but when it rebooted and I try to telnet
into the system, the computer prompts me for my password but then says that
the system is shutting down in one minute. Is there a reason for this and
how do I fix it.
Thanks

Yes. You can run multiple instances of Linux on an IBM 390.
One guy at IBM reportedly had 4000+ instances of Linux running
on a signle box. It's a very cool concept: instead of racks
and racks of servers that all need to be maintained, you buy a
single 390 and run umpteen copies of Linux: one as a DNS
server, one as an IMAP server, one as an NNTP server, a few
dozen as HTTP servers, a few as database servers, etc. There
are virutual network channels between the instances, and they
can share disk space.
390's have auto-failover, hot-swappable _everything_ and they
quite commonly run 99.99+ percent uptime. That's something
that's simply not possible with a room full of x86 machines.
Once the number of x86 machines gets large enough, the cost of
ownership of a 390 is actually less than the "many racks of
cheap shit" approach.
> I think this could be useful for System
> developement,
Definitely. That's way machines like the 390 have always had
fully virtualizable designs. That way you can run multiple
OSes on one box. Can't affort to give every system programmer
his own physical machine? Then give each one a virtual machine
or two.

Unfortunately, due to the mind-numbing backwardness of the
Intel CPU design, it is not easily virtualizable. So there's
no nice to set up multiple virtual machines on one physical
machine if you're talking about the x86.
If Intel had done a better job on the 386, we probably would be
able to run multiple virtual machines on nice cheap hardware
(vmware does it, but they put a _lot_ of work into it, and
they want some payment for that work).

You can boot Linux in Linux with vmware and there is s user space

I can't get the LPD printer daemon to start. I'm running Red Hat Linux
release 5.2 Kernel 2.0.36 on a 486. I can print (from root) by
directing output directly to /dev/lp0 but when I try
lpc start all
it returns with
lp:
printing enabled
lpc: connect: Connection refused
couldn't start daemon
I thought it might have something to do with permissions but I've
compared everything I can think of with another machine (with lpd
running) and everything seems the same. I can't find anything in my
Linux books ("Running Linux" and "Linux in a Nutshell") about this
error. Any advice would be greatly appreciated.
Thanks in advance.

Okay, so it's saying that your cdrom drive is the primary
master. What sort of a setup is this? Do you not have an IDE
hard drive in the machine? Are you currently running another
operating system on it? What does the BIOS say? It's sort of
hard to believe that your cdrom is the primary master. I've
never seen a config like this, unless your hard drive is
SCSI. I'm sort of out of my element, here, as I've no
experience at SCSI-hd based systems, although the principles
should be the same.
In any event, what output do you get from
ls -la /dev/hda
What Linux distro and kernel are you running?

The following software packages emulate PC hardware and will allow
Linux to be installed within your virtual PC on Linux:
* VMWare - Commerical
http://www.vmware.com/
* Simics - Commercial
http://www.simics.com/
* Plex86 - Open Source
http://www.plex86.org/
More useful for kernel development is User Mode Linux which allows you
to run a Linux OS (kernel and all required processes) as separate
processes under Linux.
* User Mode Linux - Open Source

There are 5 types of panels. The one you are talking about is the

THe install.readme of netscape tells you where to place plugins and
