The original problem was...:

And the answers...

1.- The most helpful was from (Russ Poffenberger):

>The cable could still be the culprit. For a test, halt the machine down to the
>boot prompt, then try "test net". It should succeed on both internal and
>external loopback tests for the interface that is being used. You can also try

>This will at least help you verify that hardware and cable are OK.

and in fact the AUI external test failed!

so I moved the cables around and then chenged it to a similar one and
the AUI test passwd OK..but still it wouldn't ping.

>From the software lab downstairs the admin told me that these tranceivers are
VERY VERY sensible to heat, so I opened 3 windows, the door (made an air tunnel) and put the tranceiver attached to a PC fan.

After taking out the CDE daemon and testing it via no-X, it pinged!!!
I thought maybe it could be CDE?? so I ran openwin (openlook), it pinged!!!
then ran CDE like /usr/dt/bin/dtlogin -daemon and it pinged!!

Was it CDE or the heat? beats me...

I am an EE and find this INCREDIBLE !!! (not too mentioned $%^$%%$^ )

2.- Other answers pointed to the cable connecctions and to assure that
they were plugged correctly and tightly..

Thanks to all the people that took their time to help out..
