Based on the above ps output, your running sendmail, not postfix. Sendmail,
by default, is configured to only listen on localhost. If your wanting to
use postfix as your MTA, then please run "redhat-switch-mail" to configure
the proper links in /etc/alternatives.

Actually having postfix running on your box should help with the above. :-)

You will still need to configure your linksys box to forward port 25 to your
linux box after you fix the above problems.

Help > nVidia on FC 2, test 3
by Doug Robson
Kind helpers,
I just upgraded to Fedora Core 2, Test 3 and then
tried the nVidia
installer using the --add-this-kernel, followed by
*custom.run.
Everything seemed to run to completion without error.
But when I booted up to run level 5 (graphic mode), as
soon
as the optical mouse light lit, normally the time when
I get the
nVidia splash screen alerting the successful starting
of X and the gdm,
all I get is a black screen. The computer is hung at
this point.
Ctl-Alt-Backspace will not yield a text login prompt.
Only a
hardware reset will unfreeze the CPU.
Looking in my /var/log/Xorg0.log tells me that:
Failed to initialize the NVIDIA kernel module.
Any Fedora users having made it successfully to Test
3, just released,
please advise what I may have overlooked.
All help appreciated.
Doug
P.S. Please carbon copy my e-mail address cdrobsonjr(a)hotmail.com

[OT] Laptops with Linux
by Henry Hartley
I know this is off topic but I'm not sure who else to turn to. I'm looking
to buy a bunch of low-cost laptop/notebook computers and would rather not
pay for MS software that I'm not going to use. I don't care if they don't
have Linux already installed. In fact, as long as I know they will work
with FC1/2, I'd rather get one set up and clone it to all the others.
The big name brands don't seem to be much help. Even IBM, with all their
Linux talk, puts Windows on all their ThinkPads, as far as I can tell. Of
course, if I won't save anything, I might as well just bite the bullet and
get what I get. It rankles, that's all and I *SHOULD* be able to save
something.

Problem with death windows smbfs mounts
by Doncho N. Gunchev
Hello,
I have some windows machines in my lan at home and wanted to mount
their shares. This works fine untill the windows machine is rebooted or
crashes. I can not kill processes that make use of the share 'cause they
are in 'D' state (ps xaw) and AFAIK such processes can not be killed
even with kill -9. Can someone suggest a workaround/fix for this? I know
I can use kde/gnome to browse the windows network directly, but this is
too slow and not all programs can make use of it. Will automount fix
the problem and if so, can someone give example configuration please.
(FC1 fully updated till today).
I also want to ask will cifs solve this problem and will it work
with Win9x?

Thanks for the info Neil. I think I do have a hang of it.. sort of anyway.
So, what you're saying is that I have to create the LVM partition using
fdisk
1st before I can get to execute vgscan??
Currently I just type vgscan and then it complains
vgscan -- LVM driver/module not loaded??
(it's loaded. The module is named dm-mod.ko right??)
