It also tells us that MS is scared of the Linux threat; why else would
they pay an "independent" lab to jig up a bogus comparison that makes
NT look like God's OS?
A few items to consider:
1. Mindcraft's NT was maximally tuned; their Linux was "out of the box,"
and they made minimal effort to find Linux consultants to help them.
(Whereas they received much MS Tech Support help in tuning NT.)
2. While Mindcraft states that MS paid for the study, they bury the
disclosure
deep within the report, rather than in the opening paragraph where it
belongs.
Suspicious behavior at best.
3. They made no mention of the *many* studies, by independent firms,
which
show that Linux/Apache leaves NT in the dust on commodity hardware
(e.g.,
single-processor boxes with less than maxed out RAM).

With the cursor on the header of the article you want to search, hit '/' and

ssh is as secure as most people need. you also should not have to export
the display as ssh can handle forwarding of X11 conections as long as
you've got an X-server running on the NT side..

So what you're saying is that you want a configuration that lets you use
a bogus address. In that case, you're going to have to change EARTHLINK'S
sendmail.cf file; no amount of changing your own sendmail.cf will help you
do that. It is EARTHLINK'S sendmail that is rejecting your message. Every
time you send e-mail through Earthlink that has a bogus From address, the
Earthlink mailer will reject it and send it back to you.

I think you're only really meant to have 4 primary partitions for

Yes. In production you should not run chat with the -v option, should
not run pppd with the debug option. Also you should not run chat with a
command line string either but use
chat -f chatfile
where chatfile contains the expect/send pairs.
(otherwise a ps auxww will display everything on the chat command line,

hmph. Just install autofs, edit /etc/auto.misc, and add this line:
cdrom -fstype=iso9660,ro :/dev/cdrom
then change '/misc' to '/mnt' in /etc/auto.master. Start autofs (as
root, of course - now it doesn't matter what /dev/cdrom's permissions
are!). Now just go to /mnt/cdrom when you want to use it.
You might want to turn down the timeout value in /etc/auto.master,
though, so you don't have to wait a full 60 seconds to eject the disc :)

No, I need to rig sendmail.cf so that gulf.net and AOL truly consider me
as part of Earthlink. Freddie.jamstar.com is my home machine. I've asked
this several times. Trust me, you're *NOT* helping.

Are you talking floppy boot, cd boot, or burned into ROM?
Most of the floppy-loaded Linux distributions I know of are intended for
repair and network diagnostic use. Tom Oehser, designer of the "Tom's
Root-Boot" distribution, has a neat little index of several such, including
Trinux, in the links on the bottom of this page: http://www.toms.net/rb/
You might also find the "cramdisk" images described here of interest:
http://metalab.unc.edu/LDP/HOWTO/Bootdisk-HOWTO-11.html
I use "Tom's" only for repair, not everyday use.

Hi,
I am upgrading my games machine (Win9x) to a celeron & 6Gig drive. I
plan to take the Pentium board & 1.6Gig drive from it and upgrade my Linux
machine (old 486 with 2 x 300Meg drives).
My Linux installation is basically Slackware96 with upgraded kernel with
diald and Samba (also XFree86). Not much else.
My question is: am I better off transferring my complete existing
installation, or should I install a completely new distribution such as Red
Hat 5.2 or the latest Slackware?
Thanks for your help.

Subject: compiler options not passed on
Date: Fri, 16 Apr 1999 10:31:01 +0200
Hello,
A closer look to the problem I posted before
regarding egcs and libiberty comes down to the following.
When I want to compile egcs for my libc5 system on which libc6
is also present I have to do :
export CC='gcc -L/usr/i486-linuxlibc5/lib'
Then I can do a proper configure for a native libc5 egcs.
Before continuing I have to go into egcs-compile-dir/gcc and edit
the Makefile where I have to set the BOOT-CFLAGS to include:
-L/usr/i486-linuxlibc5/lib.
In this way only the proper option is passed on to a bootstrap
compilation.
After almost an hour of compilation the system starts to configure
the libstdc++, libio and libiberty and put stuff in
i586-pc-linux-gnulibc1. Here the first two go fine
but the libiberty does not. Looking at the config.log shows that
CONFIGURE does not find a working compiler. The error message shown is
the one I get when I do not include -L/usr/i486-linuxlibc5/lib
in the compiler option. So this option is not passed on.
1. Why is this option not passed on to all occurences of CFLAGS when
I do configure in the main-dir(=egcs-compile-dir).
2. Why DOES (stressed) configure work during MAKE for libstdc++ and
libio?
3. What should I change to get all things work properly.
Thanks in advance.

This was quite a good post, however I found I needed to read a book as well as
the man pages to understand the permissions approach to soft links properly
when I was wrestling with a similar problem. The only hint is in the man page
for chmod which states that the settings for a soft link are ignored. To
clarify
a) Soft links will always show lrwxrwxrwx.
b) The target of the link determines permissions.
c) Attempting to change the permissions of the link will change the permissions
of the target.
I realise you, and probably nearly everyone else reading this, already knows
this. The initial post however is obviously from a new user, and we really do
need these things spelt out, something often overlooked in many man pages, etc.
