Running all the PROM (2.7) tests, all is OK, but it doesn't boot with the DIAG switch activated anymore. It performs the memory tests ok, then it halts after a few more tests with a blinking LED. Unfortunately I can't find my manual at the moment so I don't know what it means. A friend I asked for information had a list of all the LED codes, but my case wasn't in there. Perhaps her list was for an earlier PROM... Anyway, if someone knows what 0000 0100 (1=blinking), seen from behind, signifies, then I'd be grateful for a reply. In any case, I seem to be in the market for a 3/50 motherboard, if anyone has such a beast lying around.

But see RFC1597 if you want to do it "right." 192.0.0.0 is a totally bogus broadcast address. Try 255.255.255.255 or, if you prefer, 192.0.0.255. But that's not your current problem either. I suggest you run etherfind or, if you have it, tcpdump to see if the Sun can eavesdrop on the mac-to-mac traffic. If it can't, you probably have a busted receive wire or transceiver. Or maybe your pairs are swapped. Make sure "heartbeat" (also known as SQE test) isn't on on the transceiver. __________________________________________________________ Matt Crawford matt@severian.chi.il.us Java Man - ------------------------------ Date: Wed, 28 Jun 1995 14:42:28 -0400 From: wkearney@access.digex.net (Bill Kearney) Subject: Sun 3/60 and Macintoshes (V8 #17) To: Matt Crawford >I suggest you run etherfind or, if you have it, tcpdump to see if the >Sun can eavesdrop on the mac-to-mac traffic.

(summary: this is a Sun 3/60 trying to connect to some Macintoshes) I'm a bit closer. You should hear some of the bogus mail I'm getting about this stuff. I realize the bogus nature of my local net. I'm not connected to anything 'real' yet so it truly doesn't matter just yet. I think I've made an important discovery. I loaded the demo Etherpeek software (AG Group) onto another Macintosh connected to the net. I then had it grab the packets during a Sun -> Mac and a Mac -> Sun ping. Lo and behold the Sun to Mac ping reveals the Sun to be sending the ICMP packets and that the Mac *IS* responding. However, when the Mac pings the Sun, the Sun does not respond. Thus the Mac to Sun ping session just has a bunch of request packets and no responses. So it would appear the danged Sun just isn't listening. I'm not yet convinced this isn't a software thing. It's possible my kernel or something isn't configured to support the lance ethernet interface (le0) properly. Any tips on verifying that the le0 is setup properly? My alternative is to yank the motherboard (and ALL that RAM) and replace it since the ethernet interface is on it. Thanks!

In other words, I did something rather stupid and the Sun didn't stop me. I attached an AUI to the DB15 port. I also connected 10Base2 to the coax port. The sun *internally* configured for EXTTUR; as in external AUI. I was assuming I was using the COAX or internal ethernet. This was reinforced by the fact that the Sun merrily chats away OUT this port regardless of jumper settings. But it only appears to *listen* on the jumper configured port! Damn, damn, damn! DO as I need, not as I configure! Once I reconfigured the jumper to use the internal (coax) interface it worked. But I sure do know a lot about ethernet debugging now! Thanks folks!

You have to pull out the motherboard and set a jumper in the jumper block in the forward left corner of the motherboard, labeled EXTXVR. It should be jumped to use the 10baseT transceiver on the AUI port. --James - ------------------------------ End of Suns-at-Home Digest ******************************
