With 1 caveot: Linux applications *are* Solaris applications.
Scalability concerns stem from the fear of not being able to give your
applications enough horsepower. If you develop open Linux solutions,
you can always scale on up to any "big iron" UNIX you wish to.
Sun, IBM and HP all understand this (and that is why they support
Linux).
If you develop NT applications, your scalability lies in how many
machines you can cluster. (How many IIS servers does microsoft.com
have again?)

Subject: DNS serving DHCP hosts
Date: Wed, 16 Jun 1999 04:35:52 GMT
All right, I have set up a DNS server and a DHCP server on my Linux box as
per the HOWTOs. Everything works so far--computers in my imaginary domain
are configured through DHCP and can find each other's addresses through DNS.
However, how can I get DNS to automatically add (and adjust for changes in)
the DHCP assigned addresses? Currently I have to do it manually which
basically makes everything static IP's.. Any ideas? Thanks.

Or if, like us, you implemented the system using perl, tcl, and/or sql,
you don't even need the stinking recompile. I've implemented several
such systems using Linux that translated directly to HP/UX or Solaris.
Just copy the scripts and away you go.

Subject: Printing to a GDI (windows only) printer from Linux
Date: Wed, 16 Jun 1999 07:52:35 GMT
Hi there,
Up until recently I had a nice 13 computer network with
a 486 linux printer server which was connected to a HP
Deskjet 500. All of this worked perfectly, apart from
the fact that the printer was a tad too slow.
So my IT administrator, who knows nothing about this
Linux server, decided to buy a nice new Brother HL-820
_Windows_ printer.
So I can't use my Linux server to deal with the printer
requests. Is it possible to use this HL-820 printer?
I read in the documentation that you can send data
direct to the printer without intervention of lpd, so
would the following be possible, and if so, how?
Win 95 ----> Linux printer server ---> Printer
|
Win 95 ---|
If the above isn't possible, I can get my hands on a
HL-760 - would this help?
Cheers,
Oliver B. Tupman

You should rarely see that - sz usually waits for it.
What zmodem are you using? And what zmodem is running on the remote host?

You don't understand the specific special meaning of 255.255.255.255,
please read the relevant RFC's...

If such a configuation as described the running of "routing software"
would serve only one purpose, that is the wasting of bandwidth with
RIP packets.
The routing is going to look something like
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
and
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
For the client machines in such a setup.
Though it would be possible to use a user space program to manually forward,
it is far better IMHO to fix the problem in the kernel. Doing things via
an app will work for a single port, but gets very fiddly where several
ports are required of support for ICMP is needed.

I just don't see the apache icon(the icon with a big W in it) in control

Subject: Help Designing/Setting Up New Network
Date: Tue, 15 Jun 1999 14:57:55 -0400
I'm wanting to redo my personal network, and am looking for some
ideas/advice on how to best set it up.
Currently, I have 4 boxes on the network running 10baseT. However, they
are all on 10/100 cards, and I'll be picking up a new 10/100 hub in the
near future.
As for my current setup:
Machine 1 - a 486 with about a 400 meg hd and 24 megs of memory that I
use to dial up my isp and run my printer + samba. It is running Debian
2.1.
Machine 2 - a Pentium 100 with 64megs and a 4gig drive that is running
Suse 6.0 (this box is not really doing anything right now).
Machine 3 - a Pentium 200 with 128 megs and 2.5 gig drive, 4X4 ide
cdchanger running NT/win9X.
Machine 4. - a AMD K6-2 300 with 256 megs and ~21gigs of hd + scsi tape
backup (2.5 gigs) and scsi 4x6 cdchanger running RedHat 6.0. (2 - 8gigs
and 1 5gig drive)
All of the drives can be moved around and reused except the 5 gig which
is full of my mp3's.
Anyway, I want to keep one machine running Microsoft for games and so
forth. I'd also really like to setup a good linux server with one
(probably the K6-2).
So, how would you do it, and what distributions of linux would you run
(if you would pick a particular version over the others for a specific
reason - personal preference aside).
Thanks for the help,
Chris

It *may* work. However it is actually a kludge, it relys upon the datagram
being *unicast* to the router machine. Then having the router perform the
broadcast. (Note that where ipmasq/ipchains are in use this is unlikely
to work at all, unless 192.168.0.0/16 is used in the appropriate places.)
And anyway it will do the *WRONG* broadcast. The requirement is to send
a broadast to a 192.168.x.0/24 network.

Uhh.. are you sure you typed that right? You can't connect a serial port
to a parallel port. If you want slip, you'd put the nullmodem cable between
two *serial* ports.
> ike both systems to be able to share files. Right now I have nothing,
Let's hope you don't have a dead parallel port. IIRC, pins 2 and 3 on
the parallel port are data output pins, and you just smacked them with 12
volts from the serial port on the other machine. Nasty.
Check your cabling

Stay away from IRQ 15, unless you did disable the secondary IDE channel

Subject: How to connect NT machine through samba Linux box to NT net?
Date: 16 Jun 1999 12:05:44 +0100
Hi
My setup:
Linux box (LB):
A Redhat 6.0 box connected to a windows network through
device eth0, running samba, is visible for other Win boxes
on the network. This machines eth1 device is connected to:
NT box (NTB):
An NT 4.0 SP 5 box. This is connected to the LB and is given
a static ip from that machine which works fine in every aspect.
I have had it working by connecting it directly to the net,
but I lost connection when positioning it "behind" the LB.
The Net:
There is no WINS server.
Problem:
The NTB does not find any other machines in Network Neighborhood,
not even the LB.
Partial answer from arp (which looks wierd to me):
Address HWtype HWaddress Flags Mask Iface
NTB ether NTBs addr C eth1
NTB * * MP eth0
Questions:
How do I connect NTB to the NT network?
Should both my interfaces (eth1 eth0) be in the interfaces
parameter in smb.conf? What netmasks should be used?
What value do you suggest for the following parameters:
wins support
wins proxy
nt smb support
dns proxy
Does it matter if eth0 is in promiscouos mode or not?
I would be thankful for any answers/hints, please note
that I am a novice in the areas of Linux and networking.

Looks like a problem on the remote side.
When a foreign hosts closes a connection, it has to do with
authentication.
I suggest you check passwords and/or IP-ranges the remote side doesn't
allow.

You can use "Slip" either from the command line, or in rc.inet1 at bootup
depending on what you want. The script doesnt choose between slip
or cslip, that's up to whatever your system does by itself -- probably
in the kernel module.
If you want to use parallel ports and not the serial ones, you need
to use plip instead ... I have another script Plip that does this
(the same url as SLip but with Plip on the end instead).
NB: The parallel ports are not the same as the serial ones at all, there
seems to be some confusion in what you type about the difference
beween them.
