Gentlemen this is the exact syntax I am usiing. I have put it in either of
the firewalls appropriate scripts, and I have even put it in the rc.local
file to try that at one point and can't get it to work. one thing I have had
luck with is just telling the mail server to bind its listening to the
external IF of the firewall and I can then telnet to it, but getting a port
to open is something total different that is not working for me. I have told
the scripts to open ports 25, 110 and I then scan with nmap, nothing....no
extra ports are opn nothing....hummmm....

Maybe check the permissions on the /usr/man directory and subordinates, also
the permissions on the man pages themselves. Mine are:

Linux, like any real OS, dedicates all remaining memory, after the
kernel, as buffers. These buffers are dynamic in that they are resized
whenever a program is loaded. Buffers reduce disk writes and prevent
thrashing (when memory and diskspace are tight). Linux uses memory much
more efficiently that windows. That's why a memory upgrade under Linux
results in a perceptible performance increase, yet doesn't seem to
change a thing under windows.
Here's my `top' on a 256meg Linux box:
120 processes: 118 sleeping, 1 running, 1 zombie, 0 stopped
CPU states: 3.2% user, 0.4% system, 0.0% nice, 2.8% idle
Mem: 253472K av, 235064K used, 18408K free, 0K shrd, 104092K
buff
Swap: 979924K av, 0K used, 979924K free 51972K
cached
Hmmm.... It looks like I gotta zombie running around in there. Time to
go zombie slaying.

Oops. I read your original post again and see I may be heading in the wrong
direction. The MANPATH variable is not set at all in my system! Then I noticed
you are trying the whatis command. whatis uses a database built by a cron job
that invokes 'makewhatis -w'. makewhatis is a shell script that lives in
/usr/sbin/makewhatis on my system. You might want to look at the script. The -w
switch causes makewhatis to issue a 'man --path' to detemine the paths to your
manpages. You might want to try that command and see if it shows the same thing
as your /etc/man.config. If it doesn't, you might want to recompile the man
package.
Does 'man man' work?

A modest number of "dot" files don't hurt, but hundreds of them? At each
logout 2 new files are created, and never is one removed. Sometimes I look
at hidden files, e.g. .xinitrc or .bashrc. Then all I see is those dammed
.twm files, and I simply don't want that!

An easier way to boot to Linux with this setup is to run loadlin.exe from
your windows drive.
hold Ctrl when you are booting windows, then select "safe mode command
prompt" and type loadlin vmlinuz (where vmlinuz is a copy of your kernel
from /boot). This is assuming you have setup your windows partition as vfat
in Linux.

We are running Linux Slackware with SendMail installed. Both internal and
external email has been running well.
Lately, we have another site connected to us and share our mail server.
They can send and receive internal email without problem. But for Internet
mail, they can only receive. Whatever messages they send to the Internet,
they will get the following error message:
The message could not be sent because one of
the recepients is rejected by the server. The
rejected email address was [EMAIL PROTECTED]
Can anyone shed some lights on it please?
Thanks.

Hi, all!
I am looking for a utility (FREE or commercial) that will allow me to
do the same thing on Linux that Jumpstart does on Solaris. Basically, I
need some kind of a tool that will help me automate installation and
configuration of a RedHat Linux 6.X - 7.X on a server. I will try to
use this tool to figure out how I can do the same thing on multiple
servers (one at a time, several at a time, etc.)
Any thoughts or ideas are welcome.
Thanks!

Folks,
I'm hoping there is someone with the expertise I need. I have a small linux
installed on my machine that has a driver that supports my pcmcia card.
The drivers in the bootnet.img do not support my pcmcia card. How can I
build a floppy that uses my drivers so I can do a network install using ftp
to feed the files to the install procedure please.

Windows seems to be able to recognize all the memory in my machine
fine. So does BEOS.
Why can't Linux manage this?

Thanks for the tip, but I think I figured it out. The problem is
upstream from the SCSI disks - it's the RAID controller. A
fleeting error message that I hadn't noticed warned of problems
with a DAC960 driver. Turns out that the RAID adapter in this
box, a Mylex DAC960PL, is an old beastie with 2.4 firmware. The
Linux driver for this card wants to see at least v3.5. The card
is socketed for two flash ROMs, Intel N28F001BXT-120, and I
thought I could just order these chips and flash the 3.51
binaries from Mylex's Web site. Alas, this didn't work, so I just
ordered a new Mylex AcceleRAID 352 card, which is supported by
the Linux driver. Hope this works - for $700+ it better!

Anyone know what's going on, and how to fix it?

Hi Jules,
I think this is a gray area where Linux really hasn't been pushed to yet.
FreeBSD I know has disk arrays of this size. Walnut Creek CDROM runs a web
site with a terabyte of content or more.
Solaris would make an ideal canidate too in this situation. If your managment
is some what conservative.
For Linux, this is definitley a gray area. FreeBSD would be a good OPEN
source choice in this case.

Hello all Linux Guru,
I'm going to install Linux (Redhat 7.0) on my laptop (H-P OmniBook
6000), which currently has Win2000 on it. Here's what I'll be doing,
please advice if there's something wrong with my procedure or there's
something that I need to look out. Thanks in advance for al your help.
1. Repartition: 18GB hard drive by creating 13GB (NTFS) C: drive for
Win2000
2. Install Win2000, make sure it boots up OK
3. Then install Redhat Lnux 7.0, by booting its CD, and setup on
remainding 5.0GB with custom installaiton
I did this twice, but the laptop boot-up goes direct into Window 2000.
I would like to setup so I can see the selection menu in order to
choose which OS I want to use.
PLEASE HELP. THANK YOU ALL.
