Damn near anything can be a bottleneck... but I saw two things missing
from this discussion. One is... what makes you think the current
performance is bad? 40 to 150 clients is not usually considered a heavy
load, depending on what they are doing. With the sort of hardware you
are talking about, any of the OS's you mention should be able to deliver
respectable performance. In fact, the hardware is probably overkill.
It is worth noting that NT has had some ongoing problems with gigabit
ethernet performance. You might be better off with 4 100mbps cards than
a gigabit card under NT. I'm not sure if these issues have been resolved
with W2K. NetWare, FreeBSD, Linux, and other platforms have all been a
good 30% faster with gigabit ethernet than NT. However, if you are
seeing 10% network utilization, it's not likely you're hitting that
limitation.
Another thing missing from the discussion is NetWare. If what you want
is print and file services, and you want them fast, that is an excellent
way to go. While NetWare isn't the best choice as an application server,
that wasn't the original question. And while NetWare doesn't make good
use of multiple processors, it also doesn't need to for print and file
services.

Hi there!
I am a newbie to networking, but I have to configure a linux box with two
DMZ�s and MASQUERADING!
I have 5 official IP-Adresses: 212.122.23.70 and 212.122.23.104 to 107
Now I have 4 Network devices:
eth0: 212.122.23.70 (INTERNET), eth1:212.122.23.107 (DMZ1),
eth2:212.122.23.105 (DMZ2), eth3:10.1.0.250 (LAN)
and 212.122.23.106 is the Server#1 in DMZ1 and 212.122.23.104 is Server#2 in
DMZ2
My Kernel IP routing table looks something like:
212.122.23.0 * 255.255.255.0 U 0 0 0 eth0
212.122.23.0 * 255.255.255.0 U 0 0 0 eth1
212.122.23.0 * 255.255.255.0 U 0 0 0 eth2

loopback * 255.0.0.0 U 0 0 0 lo
default 212.122.23.1 0.0.0.0 UG 0 0 et0
I can ping from the inside LAN to the Internet
I can ping from the linux box to the Internet
I can�t ping the Servers from the LAN, neither from the linux box
I can�t ping anything from the Servers

Shouldn't matter though. Once mounted it is iso9660 file system for
everything below the mount point, and the type of file system that
contains the directory you mount on doesn' matter.
What does matter is which extension if any the CD file system is
created with. Is it RockRidge, (win9x, what is that called again?)
or pure iso9660. Then you have several mount options, such as
map=o/map=n, conv=a/conv=b/conv=m/conv=t, check=r/check=s
Check the man page for mount for more details.

File timestamps are always kept in UTC; localtime is irrelevant.
Display of file timestamps by (for example) ls uses library functions
to translate the UTC times to whatever you have set as your local
timezone. You can even override the system's idea of local time by
setting the TZ environment variable[1], as in:
$ ls -l xxx
-rw-r--r-- 1 jww jww 0 Nov 3 10:43 xxx
$ TZ=HST ls -l xxx
-rw-r--r-- 1 jww jww 0 Nov 3 05:43 xxx
(I am in the US/Eastern time zone.)
Linux runs on UTC. Human users like to see the local time, so there is
provision for that, as just illustrated. Your associate is confused.
It's not that the wrong time is put for everything, merely that the
wrong time (from your point of view) is displayed.
[1] If you have an account on a machine in another time zone, you can do
this to get times displayed in your own local time.

As it happens, the algorithm in question is trivially parallelized,
so it is easy to exploit multiple processors and get near-linear
speed-up. Unfortunately, the OS cannot do the parallelization for me.
For this reason, I want to launch as many threads as there are CPU's.
It is important that the detection be automatic, since the algorithm
may be launched remotely on machines with different numbers of CPU's.
Can anyone tell me (even if they believe it's a bad idea) how to
automatically determine the number of processors?
Thanks for your help.

I have two Windows 98se machines and one Linux machine on my home network
all using Linksys NICs and a Linksys Hub and a Linksys router to share my
internet connection. It all works great. When configuring the Linksys card
under RedHat linux I did download the latest driver (tulip.c). When using
Mandrake Linux it configured the card out of the box.

Subject: device is busy & filesystem issues
Date: Fri, 03 Nov 2000 16:07:54 GMT
Hi,
I have two filesystem issues that I can't figure out.
1. Often, when I try to unmount a filesystem (ie floppy or zip). I will
get "device is busy". But there is no activity and no users are using
this filesystem (i.e. /mnt/floppy or /mnt/zip). I have no idea why this
is happening and how to resolve this.
2. something is wrong with my floppy filesystem when trying to mount
ext2 filesystem disks.
here are attempts:
[janine@boco janine]$ mount /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
or too many mounted file systems
[janine@boco janine]$ mount /dev/fd0 /mnt/floppy/
mount: only root can do that
[janine@boco janine]$ mount -t ext2 /mnt/floppy/
mount: only root can do that
question-- is this something that only root should do? why can't a user
do this?
so, as root:
[root@boco /root]# mount /dev/fd0 /mnt/floppy/
mount: you must specify the filesystem type
[root@boco /root]# mount -t ext2 /dev/fd0 /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
or too many mounted file systems
can't get it to work!!
Sometimes when it does mount...and I check the size via df, I get a
bizarre disk size like 92meg for a 1.4 meg floppy.
Here is my /etc/fstab file
/dev/hda3 / ext2 defaults 1 1
/dev/hda4 /home ext2 defaults 1 2
/dev/hda1 /mnt/win98 vfat noauto,user 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/syjet /mnt/syjet ext2 noauto,user 0 0
/dev/sda4 /mnt/zip ext2 noauto,user,mode=0777 0 0
/dev/fd0 /mnt/floppy ext2 noauto,user 0 0
/dev/fd0 /mnt/dosflop vfat noauto,user 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hda2 swap swap defaults 0 0
Any help would be greatly appreciated.

I think it might be what "Dances with Crows" (the other nice person who
replied to my question) says about some sectors being bad. The disk
basically has nothing on it except the DOS file structure and those bad
sectors. I don't know whether those sectors are physically bad or just
marked bad in FAT. Is there any way to duplicate a disk like this? Thanks

Hi!
I'm using Mandrake 7.2 on a Dual Celeron machine. I have both the new
KDE2.0 and helixcode gnome installed. I use gdm that comes with gnome as my
login manager. Sice I installed KDE2.0, Each time I restart the Xserver,
the option of running Gnome upon login under GDM is not available anymore.
Meaning, the file /etc/X11/gdm/Sessons/Gnome is not executable anymore. I
can make it executable again and Gnome shows up again. But I would lke to
fix this properly. So either I find out why this happens or if somebody
knows where to place the "chmod +x /etc/X11/gdm/Sessons/Gnome" command so
each time before gdm is executed it will fix this problem up front !?

Hello,
I am using a "tail -f" to track appends to a logfile, but I found out that
changes are not reflected quickly. My experience on Unix systems is that
changes are shown instantly, but on Linux it takes a long time (minutes)

1 sec.
Does anyone have the same experience on this? Do you know how to solve this

Hmmm... though it actually works as a bug, it migth well be a feature:
all getting-password apps rely badly on the string passed (I mean, those
that, as usual, rely on the client sending a string as a password, rely
badly on it) so, if there's a lag between the password prompt and being
ready to recive the string (and a well-behaved app should expect this)
should trash out any input recieved too early (flush buffers out) so no
bogus string is passed (hum-hom... what about a man-in-the-middle app
who trash rubish between the login prompt and the moment the string is
recieved? Since the password would be rejected once and once more, most
probably the user or the sysadmin will change it... just in time for my
spy-app to catch the new one!). It migth probe all login apps trash the
buffers, but RH, being PAM dependant by default is slighty slower than
others...
