Hello,
I'm not 100% sure (about 50%, I think), but probably the forward rules must
be set to "masquerade" to do masquerading.

How did you do the mount? If you used smbmount -c 'mount /netdrive' or
whatever (from memory) then I think you just do a standard umount instead of
smbumount. But I might be quite wrong...
The command interface to Samba is a bit confusing at the moment, IMHO.
Sorry, I can't help with the printing thing as I usually print from Windows
or RISC OS to my Samba shared printer, not the other way round!

Hi Folks,
I need a Printserver wich can print over IPX.
I have to Networkprinter that understand only IPX.
Because its a Migration from Novell to Linux.
So i have to setup the Printer under Linux with IPX as Protokoll.
The communication to the Workstations is handled by TCP/IP.

Subject: Help: Max No. of clients supported...
Date: Wed, 15 Sep 1999 19:48:32 +0800
We are planning to run a Linux server in a school to provide file
service and Internet service. There are about 72 Win'98 clients that
are going to hook up to the server, and Samba and Apache are chosen to
support these services. These clients are divided into two groups. One
group has 37 clients and the other 35. These two groups belong to two
different subnets (Say, 192.168.1.0/255.255.255.0 and
192.168.2.0/255.255.255.0) Do you think a single Linux box with Samba
running is capable of supporting all these client machines? The Linux
box will have two network cards, each supporting a different subnet of
clients. The Linux box is made up of an Intel 350 Mhz CPU, 128M RAM,
and SCSI hard-drive (SCSI-2, I guess) and two generic NE2000 network
cards, installed with Mandrake Linux 6.0 BTW, the network is running on
coaxial cables... (Pretty old...)
Please help...

I used to do this using the mars_nwe stuff. There is a nwprint command
that accepts something like:
cat file | nwprint -S NWHOME -q QUEUE -b USERNAME -
The man page can show you what to do.

I have a SAMBA server and it work correctly .
I have some Windows Client on Pentium 166 Mhz , connected via Hub a 100 mb
to the Server and they work magnify.
I have added a new client : a Pentium II 450 with 64 Mb Ram .
It has the same network card of the other clients (3com 100mb).
This client is very very slow (but the hub leds are on 100mb connection).
I try to exchange the utp cable, to exchange the hub port , to exchange the
network card : i still have the problem.
The Norton system benchmark are at 216 and I have no hardware conflict.
Why I have this problem !? Please help me.

Your Windows 95 box needs to know how to get a number from the name,
either through DNS or a hosts file. I believe in Win95 there's a
"hosts.sam" file somewhere: rename that to hosts and add your linux box
hostname/number. You may need to reboot the Win95 box afterwards. The
Linux DNS doesn't come into it, I suspect - it's getting from Win95 to
the Linux box that is the problem, by the sounds of it.

Are you using the same brand/model ethernet card for both interfaces? If
so, your machine may be detecting the card you intended for the internal net
first and assigning it to eth0, which you configured to DHCP. The obvious
result is a failed DHCP request.

dhcpcd-1.xxx is included in rpm format on the Redhat 6.0 cd, and was a snap

I forgot to write that my server is a dual PIII 450Mhz and the network is
TOTALLY switched (it is realized by means of four 3COM 3300 switchs for a
total of 1 server and 50 linux box client).
I found that if a client A put a file of 102MB to client B (via ftp) and in
the same time a client C put another file of 102MB to client D,
then the bandwith of the two transmission is about 8 MB/s each (in a working
time) that it is more than the limit of 100Mb.

Date: Wed, 15 Sep 1999 11:38:39 GMT
I have set up my RedHat5.2 Linux box to accept dial up PPP connections
from a remote Win95 client, using autoPPP.
A couple of questions:
* Using my browser on Win95, I can access Apache/Linux using http://IP
address but not http://hostname. Do I need a caching nameserver or
something? Do these work OK on a standalone box? Currently, the PPP
options for the dial-up server have entries for external DNS lookup
servers. Given that the Linux box only has one modem, how can it even
use these anyway?
* Is there any way I can dial into the Linux box and get Apache to
display a certain html page. i.e. You don't have to enter an http://...
site address in the browser at the client side. Maybe some sort of ppp
script?
* What client programs can I use to access the Linux box and the
attached LAN?

The obvious answer is "for what?"
Let's see, the eight way can address less total memory and is far more
likely to suffer from memory contention causing CPU slowdown. The only
case in which it would be better is if the programs are small enough to
fit in cache and require a very high degree of interprocess
communication.
The eight way will cost a lot more, too.
UNISYS was making a ten way, in the unlikely even that you really will
want more than two processors per system. Knock yourself out on that
one.
