Subject: portscanning?
Has anyone else seen an etherpower II system lose pingability when you
portscan it with strobe?
(Strobe is a very vanilla scanner, it only does atomic tcp scans, not
udp, and not subatomic tcp like nmap does)

Hi!
My name is Norbert Tutos.I am a biginner.
I have a SMC EtherPower II network adapter(83c171) combo card, and an =
Intel 810 mainboard, I use it with the 83c170 epic 100 driver.
My card does not working, exactly once OK once no.
The IRQ and I/O are OK.
What should I do?
If you have an idea I really thank you.
Please inform me if you can help.
With kind regards from : Norbert Tutos.

There are two hints:
1. There are some timing problems with the driver done by Donald,
but there is a patched version of the driver done by
terry@beam.demon.co.uk
I have forgotten, where I found that driver, but you can
search the EPIC-Mailing-list archive to find it.
Oh yes, there is also an archive of 1999 and 2000. Just
change the Year in the list-archive URL.
2. There is driver done by SMC themselves. You can contact
techsupport@smc.com and ask for the Linux-driver.
Hope this helps,
Juergen.

There does appear to be a Linux driver for the EtherPower II card on
SMC's website. I find the drivers puzzling on the USA website as the
driver is named: epic100.exe and it is a MS Windows executable. I
haven't fired up my Win9x box to see what the executable does.
http://www.smc.com
They have a ZIP file for the driver on their European site which is what
I would expect for a Linux driver:

Subject: SMC's own driver
Hi there!
In his mail from 02/25/00 Juergen Quade surprised the list with the
information of SMC providing a Linux driver for the Etherpower II which
is capable of using the card's fiber PHY interface. On Sunday 03/19/00
Anthony Schlemmer pointed out that in the meantime this driver is
available for download at SMC's European site.
After Juergen's good news arrived at the list I mailed SMC and they
quickly sent the driver to me. Last week I finally had the time to test
the driver with the card. I plugged it in, compiled the driver on my
test system running kernel 2.0.38 and everything worked right off the
bat!
To get a rough overview of the transfer rates that could be achieved
with this setup I performed some FTP transfers. To my surprise the rates
have been below the ones I achieved with a simple ISA card connected to
an equivalent 10Base2 cable using the same computer!
Here are some possible explanations to this facts:
- a defect card (at first I would like to exclude this)
- disturbances in the fiber optic part of our network (which is used
very little at the time being)
- problems with SMC's driver
The first two points seem to be very time consuming to check. Therefore
I would like to ask the readers of this list who are already succesfully
using SMC's Linux driver with a fiber optic network to perform a similar
test and to report their results to the list! (Citation from the
Ethernet-HOWTO concerning this FTP test: "Another common trick is to do
a ftp> get large_file /dev/null where large_file is > 1MB and residing
in the buffer cache on the Tx'ing machine. (Do the `get' at least twice,
as the first time will be priming the buffer cache on the Tx'ing
machine.) You want the file in the buffer cache because you are not
interested in combining the file access speed from the disk into your
measurement. Which is also why you send the incoming data to /dev/null
instead of onto the disk.")
Thanks in advance
Ulrich

So I did a very rough performance test:
The performance variies very very much, but to give you a
number: it is about 20 and 30 kByte/sec, which is more
than 10 times less than a normal 10Mbit Card :-(
Your card seems _not_ to be defect.
But because SMC provides the source code for the driver, it should
now be possible to find out:
- why is Donalds driver not working with fiber PHY interface
- why is the SMC driver slow
If I ever get some spare time ...
Juergen.
