On the box running pppd on A the option can be 192.168.0.X:192.168.1.Y
where the addresses are unassigned and B has no address option. Or use
192.168.0.X: on A and 192.168.1.Y: on B. The main thing is that the
IP address that pppd uses as the local one on one network should be an
address that belongs to the other network.

I tried the SOHOware fast ethernet kit (two nic's, hub, cables) and
could not get it to work at all. After many emails with the SOHO people
and newer version of the tulip driver, it still wouldn't work. I finally
took it back to the store and exchanged it for a Linksys kit, which also
uses the tulip driver. But it worked with the standard driver included
with RH5.2 and no messing around. Could PnP be any easier?

repeaters don't buffer, so there's insertion delay but no buffering

for more than 2 stations, you need some kind of hub. unless you run
10base2 or other kinds of coax, in which case you can daisy chain the
cabling. but that's ancient history now ;-)

The IPCHAINS utility that works with the 2.2.x kernels (I think also with the
2.0.x kernels with a kernel patch) is supposed to make masquerading easier,
faster and have more sophisticated options.
I've only used it for firewalling, but it does far more than what I've used it
for.
Paul "Rusty" Russel is the author and maintainer of IPCHAINS, plus he manages a
mailing list on it.
Go to his home page at http://www.rustcorp.com/linux/ipchains/
What I would recommend is to shoot your question off to his mailing list, as he
answers almost every question on the list personally :)

Subject: Ethernet error on boot.
Date: Mon, 10 May 1999 21:42:12 -0400
I am trying to set up my Computer with Linux (And having fun) but I cannot
get the networking going on it.
I have tried to get my Compaq Netelligent PCI and DLink DE-220PT cards to
work but could not get my kernel to recognize them (RH 5.1).
I had then swithched to a spare LinkSys Ether16 combo card. I put my DLink
card into non-Plug and Play mode and set my Linksys card up. (DLink IRQ 3
I/O 240 and LinkSys IRQ 5 I/O 340) I had then reserved the resources in my
BIOS. When I booted up into Linux again it seemd to have recognized both
cards but I had the error "SIOCADDRT: Invalid Argument" Further
investagation revealed that both cards installed under Linux were the same
card??? They had the same IRQ and I/O and all attampts to change one would
also change the other. I finally removed my DLink card and removed Eth1 from
the configuration but the error still persists.
Any ideas or anybody know of a good troubleshooting book or web page to get
through this????

Sort of. What you would probably want to do is manually setup your
ipchains to do what you want. Then when you have the configuration you
are happy with, you use the ipchains-save command to store the
configuration. Then you use ipchains-restore in one of your /etc/rc.d
files.

Hi,
Linux on the AP400 does not appear (sometimes) to honour the ethernet
inter-packet spacing. The resultant packet stream swamps the Cisco
Catalyst switch the AP400 is connected to and creates a ripple effect
throughout our network.
The AP400 is loaded, and only single boots, with the latest Linux Red
Hat 6, kernel version 2.2.5 and network driver eepro100 version 1.06 for
the on-board Intel EtherExpressPro 100 ethernet PCI controller. System
functionality elements loaded on startup include various NIS (attempting
to contact its configured NIS server to verify and authenticate its
domain eu.barcapint.com by means of RPC), NFS and SMB (mailslot browse
packets as a transient Samba server) daemons. This is the same
environment which existed at the time of the failure with no further
applications running.
If someone knows that problems, could you please help us?
Many thanks and kind regards,
Satoshi Ohtsuka

Subject: respawning mgetty only some of the time
Date: 11 May 1999 00:48:49 -0700
This must be very simple, but I don't know how to do this. I wish to
have my modem receive incoming calls, but only _part_ of the day. So
I don't want to put this in inittab, since I'm not interested in
rebooting twice a day.
I'm interested in starting a getty on /dev/ttyS0, that will respawn,
at, say 5pm every day, and killing it at 8am in the morning (so the
computer _won't_ try to answer the phone during the business day, but
only after hours).
So a cron job seems like an obvious solution, but I don't know what
the simple way to do "respawn" outside of inittab is.
Thanks in advance if you can help me here.

Bill,
My observations, for what they are worth, is that if you're asking these
questions you're probably not all that up on Linux, which means that
Netware - which is by far better supported and more orientated to the
'Windows' world would be a better bet for your NOS.
Linux and Netware will quite happily co-exist on the same network, and will
also communicate quite happily if - say - Linux is setup as a Netware
station or server. But linux certainly won't make Netware moot if you're
looking for file and print services, network organisation and
administration.
Linux can emulate the DOS environment with things like DOSEMU, but I guess
it depends on the database app as to whether it will run in that environment
AND connect to the LAN.
