Hi,

I have an old SUN3/50 with NetBSD 1.2 installed and I'm now trying to
set up a local network with a linux box. The machines are connected
with a standard ethernet cable (BNC). I'm using the BNC connector at
the SUN, not the AUI port. When trying to configure the interface le0
on the SUN, NetBSD says that the carrier is lost. I checked the
cabling and it seems ok (length is 30m, T-connectors with 50 ohm
terminators at both ends). Am I using the correct interface device?

Thanks in advance,

I'm not all that familiar with Sun 3/50s, but I believe that le0 on
Suns typically refers to the AUI/UTP interface.

You can run "ifconfig -a" to get a list of all the interfaces
available.

Slide out the motherboard and check the dip switches nearest the net
ports. You have to use one or the other (aui/bnc) slide all the
switches over to the side the port you want to use.

Um, is the board jumpered to use the BNC port?

There is a jumper on the motherboard for this. Anybody remember off
the top of their head which jumper it is? It's not hard to guess.
I just don't remember the exact name.

NetBSD should auto-detect what port you're using I think, but the last
time I configured NetBSD/sparc I had to use the 'link0' (or was it
'-link0?) option to ifconfig to force the right type.

I'm running his exact configuration cabled to a Sun386i with an AUI
tranceiver. I read le0 from the BNC cable and it runs just fine.
Sounds like the other person who suggested dip switches might be
right. You can also test it somewhat with the boot PROM tests.

Thanks to all who answered the question. The solution is to switch the
eight DIP switches on the motherboard near the ethernet chipset from
OFF to ON. It works great now. BTW, this is also in the FAQ, I'm sorry
for wasting bandwidth.

Best Regards,

This particular machine (3/50) is not capable of switching. It's
jumpered, period.

just wait until the next poor bastard does a search on Deja News and
finds his answer before posting... then it will all be worth it! :)

taint so

You're confusing this with a 3/60 which is jumpered, check the faq. If
you've got one that is not switched, then you have a 3/50 chassis with a
3/60 board in it.

It might be that the internal DIP switches are set
for the AUI port rather than the BNC connector.
All 8 switches on S0618 should be in the ON position.

Can't answer for the 3/50 but my 3/60 has a jumper on the motherboard
that sets AUI or ThinNet

Or check the RAM. The 3/60 has SIMMs the 3/50 has soldered in DIPs.

to clarify this point again... My board is definately a 3/50 board
(message from the boot PROM) and it is JUMPERED. There is no way to
switch by software in my board. If you are still in doubt, read the
FAQ (http://doener.unix-ag.uni-kl.de/FAQ/sun.hardware.FAQ):

S0618 (by AUI Ethernet connector, switch 1 toward rear)
1-8 ON for thin Ethernet (BNC connector), OFF for AUI
