Here's my challenge:

Given what's available today, what would you need to build the most awesome
Linux server at a decent price?

It's got to have the following:

-At least 400MHz processor power (which is best?)
-At least 128MB SDRAM (100MHz or better)
-At least 50GB drive space (software RAID5 with IDE drives (heard of
UDMA/66?))
-100MHz system bus on the mother board.
-Linux 2.2.X (of course)

Who can help me fill in the blanks? (see responding messages for details)

If we can get enough of the right people in on this discussion, we will have
a really killer machine that can be built on a budget by just about anyone.
Are you game?

IT may happen, that on your motherboard the 3c508B will not work with Linux
... at all. I have spent about a week trying to get it working.
It was pinging other system (but every other packet was marked DUP), it did
not ping yet other systems at all (on the same subnet), etc.
I have exchanged it for another (cheap) card, and got it running in 10 minutes.
Don't loose (too much) time.

One possibility: find an email client that will accept an SMTP
server name in it's configuration instead of insisting on local
sendmail.  Alternatively you'll have to keep messing with
sendmail.cf.

Perhaps someone knows a better way...

-Linux:  Will the new kernel support the above features? (i.e., UDMA/66,
disk partitions greater than 20GB, Celeron CPU, large amounts of memory,
stable RAID5 implementation, etc.)

Everyone knows that this is what makes any system great.  The only problem
is coming up with the perfect combination of hardware to really do it
justice!

Big Thanks to everyone helping me pull this beast together!

Don't screw around with version 0.16 anymore.  Delete all the sources.
Find the patch to version 0.16.5.  Uncompress the sources to 0.16
again.  put the patch in the directory where you uncompressed version
0.16.  run patch with the patchfile as input.  You now have version
0.16.5.  This should compile ok.  It did for me on RH version 5.2.  I
got two warnings, but otherwise a clean compile.  The warnings were
due to a comparison between pointers of different types.  It looked
like some kind of debugging code, and I chose to ignore it.  diald
worked fine.

Good luck!

It seems that the 3c509B cards work fine ... but with some motherboards
don't work at all. One can sing how "fabulous" the card is, but believe me,
it does not work for some systems. (no any PnP-off, BIOS IRQ reservation,
config/diag/etc manipulations will work). The simplest solution -- buy
another NIC card if you have a problem. For a price of $15 (more or less)
you may save yourself a lot of (valuable ?) time.
Unless you like to solve (stupid) puzzles.

 If I well understood:

  You have a network card on your linux box and a ppp link to ur ISP.
Set up the gateway on ur win box to 10.10.10.10. Linux will route the
packet to the inside trought the default, ur ppp link. That's it! But
you will have to use NAT ( network adress translation ) to this work
fine unless your network address is registred. Little homework now: try
to find how NAT work :).

You can set the linux machine to dial whenever external traffic is
present.  A program called diald manages this.  Alternatively, the
users could telnet in to the linux machine and run a connect command.
The command could even be executed automatically upon login.

Hmm.  Diald does keep a log.  I don't think it keeps track of where
the traffic came from that made it turn on.  This could probably be
handled some other way.  In the telnet option, this would be easy.

yes, no problem.

under the diald setup I am envisioning, they wouldn't.  They would
send out packets, and linux would dial automatically.  In the telnet
option, users would have to know how to login to the linux machine via
telnet.  Special accounts could be created which dial automatically.
This isn't hard, but some users might not like it.

I don't think so.  Windows machines can't receive mail directly, to
the best of my knowledge.

Actually, as far as I know, the windows machines have to request the
mail from a mail server.  Since different users have different
acounts, there should be no problem keeping the streams seperated.

All I know for sure is that linux has support for dos, and 16 and 32

yes.  This machine would be ideal for handling the modem, and I don't
think linux would mind having the peripherals unplugged.  The only
problem is that there is some minimum ram required for linux.  Around
8 or 16 megs, I think.  This means no GUI.  It might be easier to set
everything up on a more powerful (GUI enabled) machine until you know
your way around.  If possible.

Subject: Samba: Only one Win95 machine can access Net Neighborhood
Date: Tue, 8 Jun 1999 21:52:30 -0500

I have two Win95 computers hooked up to my smb server via hub (computer A
and B). Each computer has its own unique IP (ie 192.168.1.x). When I log in
computer A, I get a dns error, press OK, and eventually get on to Windows.
If I look at the Network Neighborhood, I can see computerA, the server, and
computer B.

If I go to computer B, and login, I get the same dns error, and the Network
Neighborhood is also empty. Refreshing it does nothing but give me an error
message of the smb server not being found.

Back to computer A... If I log off and log back in, I now get an empty
Network Neighborhood.
Computer B, that previously had an empty Network Neighborhood will now show
the server, itself, and computer A when refreshed.

Weird... and confusing (for me).

Both computers have the same brand NIC, the cables are good, and each are
running Windows 95. I can ping all IPs within my network from the command
line on computer A or B whether or not the Network Neighborhood is "working"
or not. I have a valid hosts file, and a good smb.conf file (I reinstalled
Samba as well). I have not altered much in the smb.conf file, only the
server name, workgroup, and hosts allow ( hosts allow = @workgroup 192.168.1

Any help appreciated, thanks in advance...

I am in Canada using Cable modem from Rogers.
I tried to use DHCP before and it never worked on me.  Instead I configured
everything manualy,  since all the necessary information is available.  Get
IP, netmask, gateway, DNS, and domain from your cable company.  You can use
any X to configure network and I think it is easier than configuring all
files with text editor.
If you don't know how to use X window, well, then you have to modify them on
command line.

I believe he program junkbuster can be set up to log web sites.  The
following comes from the junkbstr.ini file.


# debug sets the level of debugging information to log in the logfile
#
# debug                  1      # GPC  = show each GET/POST/CONNECT request
# debug                  2      # CONN = show each connection status
# debug                  4      # IO   = show I/O status
# debug                  8      # HDR  = show header parsing
# debug                 16      # LOG  = log all data into the logfile
#
# multiple "debug" directives, are OK - they're logical-OR'd together
#
# debug                 15      # same as setting the first 4 listed above

The web address is http://www.junkbuster.com.

Also, maybe squid or wwwoffle could be configured to do the same thing.

Subject: IP Masquerading Problem
Date: 8 Jun 1999 14:05:00 GMT

Hi, I have a networking question that I hope someone reading this
newsgroup can answer.

BACKGROUND:

I have a LAN connecting a couple of computers in my house
(using the reserved 192.168.2.* IP addresses), and I recently
set up IP masquerading on my Slackware box, so that my housemate
can use my internet connection (rogers@home, through a second
ethernet card).

I use "ipfwadm" to turn on masquerading for his IP address,
and his Win95 box is configured with my Slackware box as a
gateway:

/sbin/ipfwadm -F -p deny
/sbin/ipfwadm -F -a m -S 192.168.2.0/24 -D 0.0.0.0/0

Anyhow, for the mostpart it all works like a charm. When he
first tried to do ftp, we realized that I had to load the
"ip_masq_ftp" module, but that was that.

PROBLEM:

My housemate can't get videoconferencing to work properly.
The outgoing stream seems to have no problems, but the incoming
stream won't come through. I have yet to confirm that it's not
a configuration problem with the videoconferencing software,
although I'm pretty sure this is a networking issue.

My question is, is there a module I should be loading, such as
"ip_masq_microsoftnetmeeting"? (His videoconferencing software is
MS NetMeeting) I've tried loading other modules that I had around,
such as "ip_masq_cuseeme", but (no surprise) no help -- most likely
they use different ports, so I was just hoping.

If anyone knows what the problem might be, and if it's a module to
load which one, I would be most grateful if you could email me
directly at "[EMAIL PROTECTED]" ...

TIA!

Cheers,
Brian

That's true. However quite a few folk don't have control over the nameserver
that's serving their names, their ISP's have control. So you still have
to deal with the ISP to have new hostnames added. And guess what, they'll
want to charge you for the priviledge.

Any user with a static IP should do their own nameservice in this instance.

What happens when you transfer large files?  I've done ftp installs of
Linux through my masquerade box, as well as downloaded 100MB+ files.
