I had a similar problem using RH6.0 with samba, transfering data to and from
an NT server to the RH6.0 box would cause data corruption. If you wrote to
the RH box's disk locally everything was fine, but if you copied data to or
from it over the network it would get corrupted periodicly. Upgraded samba,
but still had the problem.
Finally tried another Linux, Caldera's OpenLinux 2.3, with samba and and
everything worked fine. I "assumed" that there was something funky with
RH's file system or network stack. (I didn't go any deeper than that, so I
won't go as far to say that something WAS wrong with RH. Perhaps something
was just configured incorrectly or something. Once it was working I didn't
really care. :)

I have AMD K6-2 300mhz. It runs really well.
Mother board: I would recommand ASUS P5A. It's not very cheap but it works
great. I have 128mb ram... Sound Card: Sound Blaster 16 will do the job... I
have SB 128 but I had a little trouble with it. But, it will also work.
Video Card: ATI Expert 98 works wonderfully. I had one and did not have any
trouble setting it up running RedHat 5.2 and 6.0. Currently, I use ATI All In
Wonder 128 with 16mb ram.
Modem: External is better than internal to setup. BUT, make sure it is not a
WIN modem.
Good luck.

I have exactly the same kind of problem; What I'm
particularly confused about is that if I understand it correctly,
dhcp should be the *only* thing enabled for the interface
eth0 at the control-panel (after all, the ip address is
to be configured dynamically). But then, isn't it natural
to see the "operation failed" message? I'm really stumped.
I would really appreciate any help guys,

RealPlayer is good. but xanim (and aKtion) are **really** too slow (so
to speak impossible to use)... much slower than other video player in
Win NT. Although I have a K6-200 64MO.

Quite bugy, that's true. But very usefull, I have used it many times
and found it is a good tool, when one uses it in a good way (which is
not always the case, as other people said here).
I've forgotten to add : Visual C++ and Visual Basic.
Well, I must say that I use Linux for only one month. Maybe I'll get

The last I heard (and I just checked their web site), the latest version
of Mandrake was 7.0. If you're looking at a box labeled "7.1," it's
probably some third party's marketing attempt at work. (Macmillan has done
this in the past, marketing Mandrake 6.1 as 6.5.)

See my web site on the subject for my thoughts:
http://www.rodsbooks.com/distribs/
Linux distributions vary mostly in how easily they install and in what
sorts of utilities and applications they provide by default once
everything is installed. This latter category includes configuration
tools, so they do vary in how easy they are to maintain. For this reason,
the "best" distribution for newbies may not be the same as the "best" one
for experienced users. That's not the only dimension of interest, though;
there's also stuff like how well suited they are for specific types of
hardware, for specific tasks, etc.

Same here..
I use OpenMail from Hewlett Packard on my Linux machine. When I'm in the
office I use Outlook with MAPI and when I'm out I use their web interface
which is pretty good.. just remember you need access to the server through
your firewall.
Anyway, OpenMail can be found at www.ice.hp.com and is definitely worth a
look.. it supports Outlook/MAPI, IMAP, POP3 and LDAP... extremely scalable
and robust!

People need to realize that this situation will never come
to a head. Linux will never replace Windows, and Windows
will never erradicate Linux. Why? Well it's simple.
Users who want to get work done quickly and efficiently will
use the Windows platform and server, because it's what most
of the world knows. Yes, Linux is hard to setup. Why?
Because Linux has you interact with the installation, and
set things up by hand, so that there can be no errors. The
only problem is that you have to know what you are doing.
And there is plenty of documentation out there to make sure
that you do.
The simple truth is that Microsoft makes a damned fine
operating system, and if you can't run Windows without
crashing it, then you'd better get the hell out of Linux
before it smacks you upside the head so hard you don't even
remember your own name. NT 5 may have bugs, but it's a hell
of a lot more fun to go home at the end of the day and pop
on instant messenger to chat with some friends, then to go
into Linux and startx and then see if your kaudioserver is
running tonight or not.
There was a guy earlier who hit the nail on the head when he
said that Microsoft and Linux both have their perks, but
they aren't the only operating systems out there on the
market! There's MacOS, Unix varieties, and OS/2 just to
name a few. You have to see the big picture, and that is,
and operating system is an operating system.
I wonder if you guys aren't just a bunch of college kids
discovering Linux for the first time just to feel like a
part of something. You aren't an alliance fighting against
the "evil empire!" For god sake kids!! Look at all the
different Linux distrubutions out there charging $30 - $200
for their operating systems and server os's. Yes, in the
book and software stores that's what they charge.
And Linux is no more stable, secure, or easy to manipulate
than Windows. All you're doing is regurgitating bull crap
you picked up somewhere in a magazine, or from one of these
discussion groups. Do any of you have what it takes to
write an operating system? Have you contributed to the Open
Source kernel? Are you a guru, or just a slob playing at
home with Linux, and because you can configure your modem,
your soundcard, and your printer, you think you have the
right to trash windows. And then late at night you sneak
back on to good old 98 and play Unreal or Quake.
Hell, all these companies are trying to do is write an
operating system and software to accompany it so that you
will buy their products. Are you Microsoft? Do you work
for Microsoft? Do you understand the pressure they are
under to shell out the next big operating system every other
year? If not, then shut the hell up
I'm tired of seeing this crap all over these discussion
boards. Linux doesn't suck. Windows doesn't suck. Hell,
when I got my SuSE distrubution, there was a little note in
there that said "Hey, we fucked up, you can't install LiLO
into the /boot partition on your hard drive! Sorry!" Well
screw them. And hey, they made a graphic interface
installer that doesn't really work!!! Ain't that grand!
They all make mistakes. You can't write operating systems,
and you never will. hell, half of you probably couldn't
program your way out of a round room with one door. I don't
want to see any more of this operating system slamming shit.
It does you no good, and just makes you all look stupid.
There is no "evil empire," and there is no "alliance." If
you want to live a life of fiction thinking you are on the
side of some righteous cause, then go save the freakin world
from something worthwhile. You guys make me sick.
