Go easy on me, I am not a networking expert. But I did manage to get my
linux box at home networked and everything was great. I was able to access
it just fine from my Win98 machine at home. Then I was required by my
employer to install RAS on my Win98 to keep me captive at work.
I can still telnet and FTP into linux, but I can't access any home
directories, even when I create a user named the same as my network ID at
work. The folders are empty, even though I have files in there.
Is there a way for these two domains, networks, or whatever the terminology
is, to coexist and play nice?

Oh? Can OE go online and get your mail and news while you sleep? Many,
probably the huge majority of us do exactly that, using scripts or
programs written with *utility* in mind. Because we read this stuff,
and compose our replies offline, connect time is limited to that
required to transact our business. I can send those few replies, and
suck over 100 messages from the newsgroups I'm 'subscribed' to, and do
it in an average online time of a minute to a minute thirty per hourly
session.
Add your 125k jpeg to the mix, and assume the average newsservers speed
from halfway around the planet of maybe 2k/sec, its an extra minute of
online time to do that. We don't normally pay by the minute here in the
us, but much of the world _does_ pay by the minute of connect time,
often far more than the dime a minute Sprint brags about.
Multiply that extra minute by the number of users auto sucking this
newsgroup, and your picture just cost the rest of the worlds users a
combined extra cost ranging upwards from 500 bucks. Since my lengthy
reply is too, I'll get me coat, and snip the rest.
Cheers, Gene

Split the problem.
It seems like you not are getting any contact with the nic at all.
That is the first thing to solve. Could be a driver issue,
hardware-conflict, 'boot with pnp-os' set in bios, pnp on the nic, a
lot of things. Is this 'kernel 2.2.5-15' part of the problem, dont
know.
To get it running, I suggest unplug (maybe problem..) the box from the
net. And use lets say 'linuxconf' to configure the nic with the right
modul, and a static ip-address, (192.168.0.2, netmask 255.255.255.0)
(that is not dhcp).
If you get it up and running (and have another machine, linux or win
set at the same values (only tcp/ip if win machine, and netbios over
tcp/ip, netbui is of no help)) and a _crossover_ tp-cable you can test
if it is working.)
_then_, if that is ok, go ahed and try to solve the 'DSL line' and
dhcp part of it. (going to linuxconf and choose dhcp on the nic, and
whatever it takes, i really dont know.)

Yes.
(a) Different IP's (possibly different networks):
Your clients will have to be aware of the difference, so it's
only OK when they may really be put on two separate networks
with the Linux box serving as a gateway between them. Which is
often the case, as a matter of fact.
On the server, you will need to set up routes to both networks.
(b) Same IP's:
You will need to recompile your kernel with advanced router
option enabled and then "equal cost multipath".
I'd suggest allowing both cards to share exactly the same work,
i.e., no division such as eth0 for reads, eth1 for writes.
The cards may then be connected to the same segment of the
network, or to two different ones. In the latter case, routing
will have to be done, with routes specyfying the interface as
well as IP.
If you put both cards on the same network segment, you will
presumably connect them to the same router. Then the router
capacity will be the potential limiting factor of just how
successful this setup is.
> If NIC binding is possible is it a good idea?
Sure, if you need more bandwidth.

Windows 98 uses encrypted passwords like Win NT !
You have to add an entry to your win98-registry to keep goin !
[HKey_Local_Machine]-[System]-[CurrentControlSet]-[Services]-[Vxd]-[VNETSUP]
Inhere you have to add a DWORD-entry called "EnablePlainTextPassword"
Then change the Value to "1"
Restart your machine - now it should work for you !
I am not sure, but I think this will not work for Win NT !
Hope it Helps !

You have IRQ problems. NOt the 19 second delay between sending ATZ and recieving
OK. You do not have the modem IRQ set up using setserial as the same as
the IRQ wich your modem is actually using. These delays will mean
dropped characters and timeouts ( as you are getting.
