Hi Mark,
The only Realtek driver I know of is the 'rtl8139'. A good place to find
ethernet driver info is Don Becker's site...since he wrote and/or maintains
most of the popular drivers. You should find what you need here.

I'm having problems getting my EtherExpress16 recognized and

errors everytime with eth0 delaying and failing. Any idea?

I am not sure about your problem but here are a couple of things that
might help.
1) can you use NFS to mount something that is not beyond the firewall?
2) what kind of error message are you getting?
3) how are you setting up for NFS?
4) I just setup NFS on RedHat 6.0. Make sure you restart your portmap
daemon and then your NFS daemon. Make sure that the mount point exists
on your machine (create the /mnt/my_mount_directory ).
Good Luck,
Chip

Subject: Configuring a 3com USrobotics 56k PCI
Date: Sun, 5 Sep 1999 20:02:32 -0600
Hello,
I have spent the better portion of my weekend trying to configure my
modem... a new
3Com 56k PCI voice fax modem (not a winmodem). Unfortunately my RedHat boot
installation is not detecting my internal modem in it's appropriate serial
port... COM2 on windows. This modem works fine on Win98 but for some reason
I cannot make it to work on Linux, and I desperately want it to work on
Linux so that I can stop using Win 98! Be warned, I am an newbie to LINUX
but already a converted soul!
Here is what I tried/did/looked-up/experimented....
-I have read all the appropriate How To's
-did a setserial to /dev/cua1 got an unknown serial port
-dmesg only picks-up com1
-there are no jumper setting that I can adjust on my modem, so I could not
reset those;
-Disabled my serial port in the BIOS to no avail.
-talked with a couple of LINUX experts.
My questions are:
1- Does anyone have any experience with PCI modems besides the fact that are
next to impossible to configure?
2- Where else can I go for help?
Thank you in advance,
Alex--

Subject: on demand dial up from a central server
Date: Mon, 06 Sep 1999 01:56:48 GMT
Hi everyone
Could you help me out in the following situation?
1. I have a small lan consisting of couple of pc's and a linux box.
2. I want the linux box to be the central server for dialing up to my ISP
3. The set up should be like - when any address( say from a browser on a pc
in the lan) which is not on the lan is requested by any application - the
linux box will dial up to my ISP and establish a PPP connection so that the
application can access the requested address.
I know ( although I have not done it yet) that many people have a similar
configuration. But one thing I am not sure about is how shall linux close
the connection with ISP when the need is over.
I think I shall have to run special software ( gateway ?) on the linux box
to accomplish the task. Can you guru's tell me what step should I follow or
any pointer to my query?
Thanks in advance.

Subject: funky ip behavior: ping eth1, and eth0 responds!
Date: Mon, 06 Sep 1999 02:47:22 GMT
Problem:
I ping two separate cards in the same box (eth0 and eth1), but only one card
(eth0) replies. They both seem to ping ok, but if I unplug eth0, neither
card works. It is as if any ping to eth1 is redirected to eth0, which then
replies to the ping. Since I disabled IP forwarding, what is causing this
behavior?
Background:
I just configured a new linux box. I am a relative newcomer to Linux, and I
like what I see so far. I installed two netgear cards in the box, did a
custom red hat 6 install, and then updated the tulip drivers to the latest
version (0.91 I think). I did choose the IP forwarding option during
install, but I have disabled it in the /etc/sysconfig/network file
(FORWARD_IPV4 = "no"). I configured eth0 to use ip = 192.168.0.100, and eth1
to use 192.168.0.101. There are no errors on boot, and eth0 and eth1 come up
ok. The correct i/o addresses and interrupts are assigned, as shown in
/sbin/ifconfig.
Results of ifconfig:
eth0 Link Encap: Ethernet
Inet addr: 192.168.0.100 Bcast: 192.168.0.255 Mask:
255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU: 1500 Metric: 1
Rx packets: 0
Tx packets: 0
Interrupt: 10 Base Address: 0x6800
eth1 Link Encap: Ethernet
Inet addr: 192.168.0.101 Bcast: 192.168.0.255 Mask:
255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU: 1500 METRIC: 1
Rx packets: 0
Tx packets: 0
Interrupt: 11 Base Address: 0x6c00
lo loopback blah blah...
Now if I go to another machine on my network and ping eth0 (192.168.000.100)
with 100 packets I get the expected results:
eth0: Rx packets: 102
Tx packets: 107
eth1: Rx packets: 6
Tx packets: 1
not exactly 100 packets received and transmitted by eth0, but close enough.
Now if i ping eth1 (192.168.0.101) with 100 packets, I get this (the packet
counts are reset to zero before doing this):
eth0: Rx packets: 5
Tx packets: 105
eth1: Rx packets: 103
Tx packets: 3
As you can see, eth1 is getting the ping packets, but then eth0 is
responding. My friends, what is up?
Thanks
Bruce

Date: Mon, 06 Sep 1999 02:12:41 GMT
I saw a guy do this once in linux by going in and hacking the c code for
the network card. I'm not quite that good (yet!).
The way I do this is to use a DOS config program called 3c5x9cfg.exe
which comes on a disk when you buy the retail version of the 3com 3c509b
network card.
I have a Windows/Linux dual boot machine, at the lilo prompt I type
win98 to start windows and then hit F8 key to start in safe mode, choose
dos command line only. Then put in floppy disk and run 3c5x9cfg.exe
program which will allow you to configure card.
Try 3Com's web site, if you can't find the program I can email it to
you.

I am connecting to my ISP using Kppp. I dial in,
connect, use PAP auth. and log on to the network. I then open netscape
and nothing happens. I see it is looking for a host, and it cannot find
it. I have been able to ping IP addresses successfully in a terminal. I
have even been able to open up a web page if I type in the IP address
instead of an alias.. I cannot ping WWW addresses. I assume that I have
a resolving problem. I edited the resolv.config like the following (the

[..]
Is this one of the new 3Com 3CP5610 modems? Their older PCI modems are
all software modems, but the 3CP5610 and 3CP5609 may be Linux compatible.
There is a special sequence of steps using setserial that you will have to
perform to use a PCI hardware modem-- they are relativcely new and not
automatically recognized by Linux.
Please check the instructions at:
http://www.math.sunysb.edu/~comech/tools/PCImodems.html
You may want to check first for your modem at:

How sure are you its not a winmodem? The last thing I heard was
that no manufacturers are making real modems for the PCI bus.
I hope I'm wrong!!

Thank you so much. I've been tearing my hair out trying to find out why, and
your suggestions look like they did the trick. I just recompiled my kernel

First, Samba (nmb/smb) and ping (ICMP) have nothing to to with each other. Samba
"typically" uses a WINS server or a lmhosts file for name resolution. It can also be
configured to use DNS (typically a last resort!!). Ping uses the resolver libs which
use
either the hosts file or DNS for name resolution. I'd be willing to bet that your Win95
box is dialing out to the internet because you have not listed your linux box's ip
address
in your Win95's hosts file. So it is trying to contact the DNS server of your ISP to
resolve wild.fredy.com. Another trick I learned (to keep your system from falsely
dialing)
is to add the "workgroup/domain" name to the hosts file or DNS server. ie. If you are
using workgroup as your "workgroup" name
192.168.20.2 wild.fredy.com wild workgroup
be sure that you also specify fredy.com in the "domain" section and also the "domain
suffix search order" of tcp/ip properties in MS.

I hope this was a typo... lmhosts.sam is the "sample" lmhosts file provided my MS. If
this
is not a typo, then rename "lmhosts.sam" to "lmhosts"

If your specifing a WINS address, did you enable the "wins support" component of
Samba??
This tells Samba (nmbd) to be a WINS server. Then when your 95 box comes up... it will
register its self with the WINS server.

> 1. How do I get Win95 to ping properly?
You will need to put the ip address of your linux box in the "hosts" file on your Win95
box. By doing so, your Win95 box will not try to issue a DNS query, which is probalby
causing your system to dial out to the internet. You should also put the ip address of
your Win95 box in the /etc/hosts file of your linux box.

First, enable the "wins support" as mentioned above. Also make sure that both win95 and
samba are configured for the same workgroup/domain. Then both Samba and win95 will
register with the WINS server and you will then be able to see both systems in "Network
Neighborhood". If you want to go one step further... configure Samba to be a "logon
server/domain controller" and then configure "Client for MS networking" to logon to the
domain.
