Yes they work! go to www.artisoft.com to first get the jumper data for
your specific card.
for my Artisoft AE/2C card the jumpers are set as follows
Heres a ascii picture of the jumpers on my card which are near the
bottem of my AE/2C card
N A 816A B C D
x : : x x x: :
IRQ 10
What that means SEt card for Novell (ne2000) compatible mode
card should be set for 16 bits, Address is 0x300 IRQ 10
Then go into your Kernel and add NE2000 support
if all is right Linux should see your card and set it up for you.
NOTE! sometimes IRQ15 is used for Ethernet so try either one if the
card is not working or probed by the Kernel.

Yes, as a router, absolutely no problem.
Thee probably exists somewhere a kernel hack to make it work as a bridge
or brouter, but this is best handled by custom hardware intended for the
job.

May be you should change the /etc/hosts file. I suppose that your
/etc/host.conf looks as follows:
order hosts,bind
multi on
So your system will first check the hosts file, then the dns server.
I guess the latter will time out and causes a long startup of Netscape.
So putting your tcp/ip address and hostname in the /etc/hosts file, would
avoid checking the dns server. Your /etc/hosts should then contain the
following:
127.0.0.1 localhost localhost.localdomain
<your_tcp_ip-number> <your_full_hostname> <short_hostname_or_nick_name>
I'm not hundred percent sure, but I think this will solve your problem.

Why do that? You'll spend more time and money on hardware/configuration
then if you were to just buy a regular hub. There are some 8-port 10-bt
hubs listed at shopper.com for $36.
Unless you are wanting to connect multiple types of networks together (like
10BT, 100BT, Token Ring, Serial, whatever) ... in which case you want a
Bridge and not a Hub. There is a Bridge HOWTO at the Linux Documentation
Project.

I'd recommend the efax software package, and a 5-port modem card that
offers Linux support. There is one that is featured in a lot of catalogs
that brags about Linux support, but I can't think of the name of it off
hand. I'm using efax with a regular faxmodem and it's working great.

Hi, Sebastien,
Yes, it will. I tried this, cutting my machine off the rest of the net
and running a local DHCPD.

probably not, but this is not necessary. Different instances of VM use
different hardware addresses. I dont know how a VM determines it or how
it avoids collissions with other VMs / Hosts, but it works anyway.

DHCPD wont assign a "range" of IP addresses. It will try to reuse the IP
for a given MAC address. If this is not possible, it will assign the
next one in the range. Anyways, MAC-addresses are - and have to be -
unique, even between different instances of VM on the same host.

Yes, you did give the Windows box a username at some point in time. Try
using the "Log Off User" command from the Shutdown Menu (win95) or the
start menu (win98) and logging back in again. It's likely that you just
don't remember entering the username because in most instances it will
only ask you once.
If you still can't get it to ask you, set "Primary Network Logon" in the
network control panel to "Client for Microsoft Networks" and then the
logon box will appear..

Subject: gateway: What am I doing wrong?
Date: Thu, 19 Aug 1999 14:57:04 +0900
Hi,
With all the answer from various experts, I am still having problems
in installing network.
ifconfig lo 127.0.0.1 => fine
route add -net 127.0.0.0 ==> fine
ifconfig eth0 166.104.88.108 => fine
route add -net 166.104.88.0 ==> fine
route add default gw 166.104.88.1 ==> Ouch!!!
After executing the previous steps, if I type 'route' it shows the
first two lines(networks) and stalls. 'route -n' shows the third
entry(gateway) properly.
If I add 'netmask 255.255.255.0' in adding gateway, the 'route' shows
the entry properly. Of course, the packet does not find the gateway
properly while it finds the hosts in the same subnet. What am I doing
wrong?
Thanks.
Youjip
=<previous postings>==
Dear all,
I really appreciate your detailed replies. Unfortunately, I am still
struggling with my linux box.
1. 'route -n' seems to generate what I expected.
2. 'route' stalls.
3. ping 166.104.88.107(host in the same subnet) works properly.
4. traceroute 166.104.88.107 stalls.
5. ping 166.104.88.1(gateway) stalls.
6. traceroute 166.104.88.1 generates interesting trace.
>From the host in the same subnet, I can ping to THE machine(named
sobaek).
But, I was not able to telnet nor ftp to sobaek.
Help!!!
