Subject: Re: Multiple ethernet support for Plan 9

Hello Russ,

You wrote a few monthes ago:

However I cannot find the line in my cs.c.
My cs.c is original one.
I cannot find any boddle for cs.c.
Where is the cs.c?

I have finished compiling new kernel and others except cs.c.
Booting new kernel, my cpuserver fails because he cannot dial
to my cpu server.

Thanks,

Presotto made some pretty extensive changes
to all of ndb.  You need http://plan9.bell-labs.com/plan9/update/ndb/ndb.tar.xor
and 8.xor.  Then do
	8.xor ndb.tar.xor /your_plan9_cd/68020/9gnot >ndb.tar
to recover the tar file.  Untar it into /sys/src/cmd/ndb and 
recompile everything and you'll be good to go.

Before you go through all that trouble (which you should
probably do at some point, but it's a fair amount of work),
you might try changing line 710 of cs.c from
		if(myetheraddr(addr, "/net/ether") >= 0){
to
		if(myetheraddr(addr, "/net/ether0") >= 0){
and see if that solves the problem.

Hope this helps.
Russ

Hello Russ and David,

My multi-ether system began to work, so I am now testing 
the system.

Today I found a kernel bug.
I should report you the problem.

Executing snoopy without options causes a system panic.
The panic comes from the codes in snoopy.c
>	if(pflag && write(cfd, "promiscuous", sizeof("promiscuous")-1) <= 0)

Thanks,

You're using a 3Com card, right?

Edit ether509.c.  In particular,
the end of ether509reset() currently
reads:
	/*
	 * Set up the software configuration.
	 */
	ctlr->card.port = port;
	ctlr->card.reset = ether509reset;
	ctlr->card.attach = attach;
	ctlr->card.transmit = transmit;
	ctlr->card.intr = interrupt;
	ctlr->card.bit16 = 1;

	return 0;
but you should add 
	ctlr->card.mode = mode;
in there somewhere (probably right after the ``intr ='' line).

Recompile and try it again, and let us know.

Russ

Hi all.  If you're trying to use David Butler's
multiple-ethernet kernels that I posted boddles
for a couple months ago, you might notice that you
can't access machines on the local network.  This
is because ipconfig isn't getting run by termrc/cpurc.

If you have a line similar to
	if(test -e /net/ether/clone) ip/ipconfig
in /rc/bin/^(cpurc termrc), you should change it to
	if(test -e /net/ether0/clone || test -e /net/ether/clone) ip/ipconfig
before attempting to use the new ethernet drivers.

Hello Russ and David,

I have fixed following your advice:
>	if(test -e /net/ether0/clone || test -e /net/ether/clone) ip/ipconfig

OK. My terminal began to talk with outer systems by telnet.
Thank you.
