You'd be amazed at just how anal-retentive the Navy gets. With
powerplants, at least the steam type, they are so anal that they don't
computerise it but rely on a manually operated system and people working
18 hour days. It's almost a miracle that meltdowns don't occur on the subs
and carriers. This anal-ness is why you don't join the Navy to get job
skills. The skills you get would be more appropriate in Russia becuse it's
so backward.

By default "ps" show only ~80 characters/line. You can add "w" to the
list of arguments to show more characters (and you can add more than
one "w"!).
If you just want to know whether /usr/local/apache/bin/httpd is being
used, you could try "fuser /usr/local/apache/bin/httpd". (See the man
page for fuser(1).)

Ok, have to get a few things out of the way to
begin with.
We have to make sure that we're booting to DOS
in the same fashion. I have a boot disk that has
on it DOS (command.com), FDISK and all the other
DOS related commands (doskey, edit, format...)
and MSCDEX.EXE and CDROM drivers. I put this in
the floppy drive and reboot the computer and it
'boots' using 'DOS'. You can't use FDISK while
in windows, the drive would be active.
As far as the 'large disk support' goes I don't
think i've ever used that. My largest drive is
only 2.1GB but still, i've never had to use it.
FDISK could be hanging if your trying to use it
while Win98 is running - can't do that.
And for the problem with explorer reporting that
your 4GB disk is only 1.63GB. Here explorere is
referring to the partition that you are using
currently. For example, if i'm on C:\ then the
size of C:\ will be listed by explorer. I could
be wrong here, the above assumes that your win98
partition is ~1.63GB in size...
Just another question. Did you actually wipe
your entire drive clean? By this I mean did
you delete all the partitions on your drive
using FDISK (DOS) before reinstalling Win98?
To do this you should of course have a working
boot disk that allows access to your cdrom.
Its hard fixing problems like this over a
newgroup, I can only give partial responses
at a time because I can't see the entire
problem all at once, just bits and pieces.
The instructions below have worked for me
on many occasions without difficulty. I know
its frustrating but stick with it and things
will work eventually.

No question, go the IP_Masq route! :) It costs you nothing extra, though
some functions will need to be specially configured.
OTOH, if you can get a "Class C" network for free (note that "Class" terms

Out of curiosity, is that figure for the MCSE the cost of the exam or the
training and the whole shebang? I have a suspicion I would be able to have
more fun preaching linux if I could wave an MSCE in people's faces. And how
hard can it be? I've flipped through the books in stores and everything was

Hi all,
I'm having a great deal of trouble executing my CGI scripts as well... I feel

3. In my srm.conf file, I have the following entry:

I'm still getting the 403 error... can anyone tell me what I'm doing wrong?

You have to delete the Linux partitions with some type of linux disk
utility such as fdisk first(much more powerfull). I would first boot
linux with a linux boot diskette, go into fdisk and delete all native
and swap linux partitions.
Then reformat your hdd in DOS and recreate the partitions. Keep in mind
you have to install linux beneath 1024 cylinders. So, when you set up
the Linux partition using Linux fdisk for example, make sure the range
field is kept under 1024 cylinders. If you're using Lilo, make sure to
have the partition that hold dos/windows also boot up Lilo. That way,
when you start your computer, you can enter dos or whatever the name of
the partition is to launch dos or windows, or just hit enter to launch
Linux. Also, it is easier to do if you install dos/win first. I would
set up three partitions if you have a 4g hdd and allocate 1g for linux.
That way, you would have approx 950m and dependly on the memory 32M+, I
would just allocate approx 20m for swap. Hope this helps.

The web page mention steps for upgrading to kernel 2.2.3 under
Mandrake 5.2/5.3, it doesn't say same rpm packages can be
applied for RedHat 5.2. Can I use the same rpm packages in
ftp.sunet.se/pub/Linux/distributions/mandrake/updates/kernel2.2/RPMS
to apply to RedHat 5.2?
In other words, are rpm packages for mandrake linux interchangable
for RedHat Linux?
I couldn't find kernel-2.2.x.i386.rpm for Redhat yet, checked
several Redhat mirror sites, no success so far. I need a
newer kernel than 2.0.36 because RedHat 5.2 couldn't handle

Interesting... What you are describing distinctly resembles make. Why not

#!/bin/make -f

The thing is *easy* to port. So easy that it makes a nice background hacking

Update syslogd to 1.3-3x or thereabouts. It fixed the problem for me.

Two salient points. One is that you will rarely work as root. You
will only login as root to install or remove packages and update
configurations typically. Furthermore, your family members will not
be running as root, so they can't accidentally delete an important
file. Program crashes will not take down the system.
rm -rf / is a pretty hard combination to accidently type.
Contrast this with windows where all users run as root all the time.
Programs regularly crash the system. Windows has no security model
whatsoever. Any user can delete the system at any time. There's not
even a concept of multiple users with different permissions for
accessing files.

You can disconnect the power button if it's that much of a concern.
Then configure your kernel to power off the system on shutdown. (I
know that doesn't make sense to you now) I have had a couple of power
outages; they caused no problems at all on subsequent reboot.
Ctrl-Alt-Delete functions as you expect.

This does not make sense. Linux utilizes the Intel architecture's
protected mode. This is part of the reasons why applications cannot
crash the system and why users can't just do something like write to
the disk in a raw fashion (unless they're logged in as root which does
have access to the hardware)
The unix security model, while certainly not a panacea for security
issues, is venerable for good reasons. And security problems are
fixed in short order in Linux. Furthermore, the aforementioned
security fixes address problems that rarely affect home users.

What do you mean by "give me the mouse"? If you mean "don't give any

No, you don't. That's for the user to configure, via a utility like
xset(1x).

You can probably do what you want by looking at a series of
MotionNotify events. Looking at hardware-specific data is just The
Wrong Thing To Do (TM) under X.

Subject: Re: Increasing the number of pty or tty to 512 ?
Date: Mon, 15 Mar 1999 11:36:43 -0800
Dave,
Is that an option in the makefile or somewhere in the include file that I can
change ?
I notice that at line 34 of " /usr/src/linux-2.0.36/include/linux/tty.h"
#define NR_PTYS 256
Is this where I should change. Notice that the comment right above that line
do not recommend changing it.
Also in this file: "/usr/src/linux-2.0.36/include/linux/kdev_t.h , the number
of bits for the minor
is 8 bits which turns out to be 256 tty's and 256 pty's for a type of device.
I wonder if there is any
way to increase the number of minor numbers from 256 (8bits) to 65536 (16
bits). If you look further
down (line 87) of this file, you will find there is a possibility of having
16 bits for the minor. But this
portion is disable (#if 0 ....). I wonder what would happen if I activate
that portion and use 16 bits for the pty and tty. It seems to me that if
minor portion has 8 bits, then the major will have 8 bits too. But if the
minor has 16 bits, the major can have 16 bits too. Will this change impact
the mknod command ?
If this does not work out, I am thinking about to borrow other character
device for the tty and pty.
For example, the isdnctrl0 ~ isdnctrl255 are character devices too. But I
doubt this will work, since the type of devices are identified by the major
type, right ? For example, the pty has major type of 2 and tty has major type
of 3. So the only way is to expand the minor portion of the pty and tty
device.
Thanks
James
