use this driver 'ne2k-pci' driver,
Look at the Interrupt (IRQ). It's '4'. That's usually used by
one of your COMx ports. Try changing the IRQ to something else
that's not in use. On my machine, I'm using IRQ11. Let me know
if that helps. Also, if your network card is a PCI card that is
a clone of an NE2000, you should be using the 'ne2k-pci' driver, not
the 'ne' driver.

ipchains allows you to specify rules that include the port as well as the
address.
You can enable outbound ftp access while blocking the rest of the net by
placing port-specific MASQ rules before a more general REJECT rule. If
you want to prohibit ftp, you would place an ftp REJECT rule ahead of a
more general MASQ rule.

Some people prefer the Command line. or have just enough ram
to use the CLI where as the X windows System will not run well. I just
got a old IBM 5412 VGA monitor now. Color but YEECH! It took me over 4
hours of working Inside the monitor to get it working right.
(Aparently the original owner tweaked it for a custom configuration.
it came with a tiny screen, weird scanning frequencies and god knows
what else! (mayhaps if I knew what the orignal user modified the
timing for.. I could have used it with out cracking it open to fiddle
with the vertical size, v-line and v-center controls)
Hey! it was Free! and now I upgraded from VGA mono to VGA color. I
personally wonder if its really a DOWNGRADE. the dot pitch stinks!
AS for browsers. I have given up on Netscape for daily use and
I use the lynx browser for daily work. for my needs it works well and
does not have that "World Wide Wait" mentality of loading pictures
with frames or CGI or Java.
AS for The Xwindws system itself. I am futzing with it on the
side. but for real work I use the CLI exclusivly. Although If I ever
do go 32MB ram.. that might well change.

I've installed 2 3com ethernet cards.

Ok, I know the answer has been given before and trust me, I've looked but my

box when I install 2 PCI NE2000 clones. Each card by itself is fine, and I
have turned off all p'n'p stuff in case that was causing problems but still
no luck.
Anyway, if anyone has any suggestions please let me know.

Hi.. I was just wondering if anyone is using the SMC EtherEZ (8416) card
with any version of Linux and has it running properly. In a number of
documents, I have read that I need to install the 8390.o module and the
smc-ultra.o module. The 8390 works fine, but the other gives me an error
that there is no Ultra card found, io=(0x0) or something to that effect. So
if anyone has had any experiences with this card that they would like to
share, it would be hugely appreciated!
Thanks!

If you don't enable "Win95 bug workaround" in the kernel configuration

The problem is (almost certainly) your routing setup - one network card
is set as the route for the remote subnets, and the other is only used
for its own subnet.
Set appropriate routes for the whole network on *both* cards, and if you
want proper automatic failover, set up some kind of cron script or
daemon that detects outages with periodic pings and reconfigures the
system as needed.
Bowdlerise and post the output from /sbin/route if you need specific
help.
Enjoy

Subject: VPN Setup - Have ??'s
Date: Thu, 02 Sep 1999 07:29:03 GMT
Hi all,
New to this group. This may have been hashed around already, so please
excuse the question if that's the case.
I need to set up a VPN connection to my hardware vendor. What I have is a
Win98 workstation (frown) that connects to the internet through a linux box
acting as an IP Masquerade through a cable modem. My ?, or ??'s i guess
are, 1) do I set up a separate box from my IP Masq box, and 2) if so, do I
place it between me and the IP Masq box or between the IP Masq box and the
internet?
I've scanned the HOW-TO's and books that I have, but no clear discussion on
this point.
Any help on this would be most appreciated. Thanks
Tony

Subject: Re: PPP hostnames vs IP
Date: Thu, 02 Sep 1999 01:53:04 GMT
Your problem *is* that you don't have a /etc/resolv.conf file
The resolv.conf file provides the IP addresses for the DNS servers
your system will use. These DNS servers will provide IP addresses
for named hosts (that is, you ask for "netscape.com" and DNS replies
with it's IP address). Perhaps you should go read section 5.5 in the
NET-3 Howto; this explains the intricacies of the /etc/resolv.conf
(or /etc/nsswitch) file.

In RH5.2 it was done by setting NISDOMAIN="whatever"
in /etc/sysconfig/network. This makes it set the NIS domain on
bootup. I imagine RH6.0 isn't too different. (I'm a Slackware user...)

So you are networking already without an ethernet adapter ;-) Of
course you can connect computers via serial or parallel ports, I've
even seen them connected via MIDI (that is a port intended for
synthesizers). Ethernet is much faster, though, and it is also
inexpensive.
>Can anyone point me in the direction of some basic learning

For a start take a look at:
NET-3-HOWTO
Networking-Overview-HOWTO
Unix-Internet-Fundamentals-HOWTO
These can be found under /usr/doc/howto/en in SuSE-6.2, the location
probably varies with other distros.

Subject: Re: Network Address Translation
Date: Thu, 02 Sep 1999 01:47:09 GMT
On the original question...
1) Read the IP Masquerade mini HOWTO
You may also want to read - The NET-3 HOWTO (general TCP/IP networking)
- The Ethernet HOWTO (Ethernet networking)
- The PPP HOWTO (PPP networking), and
- The Firewalling and Proxy Server HOWTO
2) Compile IP-Masquerade into your kernel
3) If you are running the Linux 2.0 kernel, obtain the IPFWADM tool
from xos.nl. If you are running the Linux 2.2 kernel, obtain the IPCHAINS
tool (I don't *know* where, but I believe that xos.nl has it)
4) Configure some firewall rules if you want
5) Configure some firewall rules that involve IP Masquerade
That's it.

The same goes for SuSE-6.2 :-(. They also omitted --with-smbwrapper

Some ISPs dynamically assign the DNS server address,

How can I configure Linux to retrieve the name
serve address via PPP?
Or at least - how can I find out the assigned name
server address after the PPP connection has been
established? I did not find any pppd or ipppd
configuration options to accept the DNS server

Hello out there,
I have a question about NETSCAPE 4.6 / 4.61 and JAVA. On some (not on

the URL

with JAVA enabled. Without JAVA there's no problem,
I read about the wrong fontpath-settings, but this does
not seem to be the problem, since chkfontpath --list prints:
Current directories in font path:
