Yeah, the 3c509 has been supported for ages. I *did* have trouble
getting a PnP version to run once (back in the 2.0.29 days I believe),
but IIRC I ended up just having to download a newer driver.

Ouch, that bites.
Normally in this case Linux is around 10-15% faster than NT - for ftp
put I see around 920Kb/sec under Linux 2.2.5 (RH6) vs. 800-850 Kb/sec
under NT (Server 4 SP3) with a 3Com 3C509B PCMCIA card in my IBM
Thinkpad 770 (233MHz MMX, 96Mb RAM, standard 2.25" HDD).
I neither case should it be a CPU-straining activity - my old Dell
200-MMX desktop machine used to manage from-memory transfers (e.g. NFS
write) consistently exceeding 7Mb/sec with its built in 3Com Cyclone
100-BaseTX interface, using Linux 2.0.36 (RH 5.2) to a quick server.
Maybe the Xircom driver sucks :-) Have you looked for a newer one? What
Linux version are you using?

Hi!
Please give me reason why I can't explore my linux. This is the
condition.
I have two pc, let say LinuxA and LinuxB. I installed smb inside both
of them. I want to browse those pc from my windows. Yes I can see them
in Network Neigborhood. But I just can explore pc LinuxA. I can't
explore pc LinuxB.
I'v check samba is running in LinuxB. And also with the parameter.
When I try to connect to LinuxB, windows give me error message like
this: "\\LinuxB is not Accessible. The network path was not found."
Well, what should I have to do?

In this case then, I would start suspecting setup somewhere, because it appears
to me that they are not communicating at all together. When you have a machine
ping itself, it is usually pinging just the card, and there shouldn't be any
packet loss there. I would also start suspecting your connection to the hub, or
the hub itself.
I once had a problem similar to this, and found that the cause was that the hub
needed to be reset (turned off and back on again.) Other things to check would
be whether you are plugging your network cables into actual ports on the hub,
and that one of the ports is not an uplink port on the hub. If it is an uplink
port, try changing out of that port and into a different port.
Another way to check this is to get an uplink cable (or peer-to-peer cable) and
do a direct connection between the two computers to see if the hub is causing
problems.

I'm not sure about this one. One thing to note though is that if this does in
fact work, it is a huge security hole that you will want to fix once you have
it working properly.

You need to hammer a six inch nail into your forehead and write
a driver to interface with your biological neural network.
If diald is continuously connecting it is because something is
trying to send data across the link and diald hasn't been told
to ignore it. Fix the source of the data or tell diald to do
what you want.

The 3C509 is one of the commonest ISA ethernet cards around.AFAIK,
every Linux distribution includes support for this card, either
compiled into a kernel or as a loadable module.
However, you may need the DOS setup program if you don't have it
already. I suggest you reconfigure the card, switching off PnP and
setting IRQ and IO values manually. You get fewer problems that way.
You can get the 3Com config program from the 3Com website.

I have configured a Linux (RH 6.0) dual homed host. However
telnet to eth1 is deadly slow. It takes almost a few minutes

I had similar problems when I tried to access the webserver

ifconfig shows both eth0 and eth1, I can ping eth1 and eth0.
eth1 works, but everything goes slow...

Telnetting to a 192.168 address won't work - those are private
addresses, not Internet ones. If you can't telnet to the *firewall* it's
because something is set to block it (ipchains/ipfwadm rules, tcpd,
etc.) or because it isn't running telnetd.
The only way to enable inbound connections from the internet to the
192.168 machines is to have the firewall forward each one of certain of
its own ports to a port on those machines (the port numbers can be
different).
e.g. if you forward firewall port 234 to 192.168.0.7 port 23, then you
can do
telnet firewall 234
to connect to 192.168.0.7

Something is trying to use the Internet connection - a common cause of
this is DNS lookups, which can be mitigated by running a cacheing DNS
server locally. e.g. If you are running Samba for local networking to
Windoze boxes, control its broadcasts and its use of DNS, and make an
lmhosts file.
Try running diald with logging to see what is causing the dialup.
Another way to tackle this (instead of taming the application) is to
configure diald to ignore whatever it is.
There is no "fix all" law for controlling dial on demand - the way
Windows does it is manually, by shoving a pop-up box in you face every
time something tries to dial. Having it fully automated requires that
the diald rules match the traffic pattern on your machine.
I would advise you to persevere - it took me 2-3 hours with my parents
machine, but it is now the slickest thing imaginable - dial on demand
for surf, automatic mail pickup when online and at other off-peak times,
you name it....
