[Sunhelp] Problems with Sun3 and Ethernet network

[Tim Matthews]

Gday. I have recently acquired a Sun3/60 and am trying to get it to talk
to my home network.

Setup:

10 Mb Ethernet hub
Sparc 20 (le0, Solaris 7. IP 10.0.1.99 NM 255.255.255.0, default route
le0)
Intel Linux (eth0, IP 10.0.1.1 NM 255.255.255.0, default route eth0)
Sun 3/60 (le0, SunOS 4.1.1, IP 10.0.1.98, NM 255.255.255.0)

sun3% uname -a
SunOS sun3 4.1.1 2 sun3

sun3% ifconfig le0
le0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
     inet 10.0.1.98 netmask ffffff00 broadcast 10.0.1.255
     ether 8:0:20:7:ea

sun3% netstat -nr
Destination	Gateway		Flags	Ref	Use	Interface
127.0.0.1	127.0.0.1	UH	1	456	lo0
default		10.0.1.98	U	0	620	le0

I try to ping the Linux or Solaris box from the Sun3 and get 100% packet
loss. Looking at the transciever on the Sun3 and the Ethernet hub, I get
activity lights from the pinging on all three boxes.

Snoop on Solaris and tcpdump on Linux show echo requests from the Sol and
Lin boxes, but no responses. Snooping the sun3 pinging from the Sparc 20
shows no
traffic.

I have manually stuffed the MAC addresses into the arp caches on all three
boxes - still nothing.	

All the other machines on the segment can talk to each other, and the
transciever is known good.

Any ideas ?

cheers,
Tim
