I have a SUN 3/60 with OS/4.0.1 and a Sun 3/80 with OS/4.0.3. I am experiencing an unusual problem. I have both the /etc/hosts file and /etc/ethers file configured correctly on the net for both machines. The net daemons are running. NFS is not. I can do 'spray' and 'ping' from the 3/80 to the 3/60. I can do the same on the 3/60 to itself and the 3/80 to itself. But, I cannot make the 3/60 talk to the other machine. Neither ping nor spray work from the 3/60 to the 3/80. We had isolated some enet hardware problems and replaced the cpu board on the 3/60. Now, selftest and the extended ethernet diagnostics run fine. Has anyone had a similar problem and how was it fixed? //Tony

I know I've pulled my hair many times before realizing I misset the broadcast or something like that. Spray and ping shouldn't rely on /etc/ethers at all and should only rely on /etc/hosts if you specify the target in hostname format. Do an 'ifconfig le0' and confirm that both machines are using the same broadcast, same netmask, same trailers (we prefer none). And of course check that the interfaces are up ;-) _T
