Thinnet networks are subject to something akin to "standing waves".
The signal "bounces" off of one end of the cable and back. This results in
an "echo" which is 180 degrees out of phaze with the next incoming wave...
The two cancel out and you end up with a dead spot on the cable, where if
you plug something in, you get no response.
The Ethernet terminators are there to reduce or eliminate this, which is why
they are at the physical "ends" of the cable.
They are not always successful.
You may be seeing the same.
You may have a bad "T" connector as well. I've seen more bad "T" connectors
than one would expect.
Check your lan cables. Make sure that the center pin is not being pushed
into the socket when you plug it into the Ethernet card or T connector. This
will also cause problems. The center pin must not move so it can penetrate
the receptacle.
Since your LAN setup worked for awhile look for a physical problem of some
sort.

hi jose,
yes u are right, it was a mistype. i would have noticed such a dumb failure
because i checked all settings approx. 100 times.
of course
linux box is at 192.168.0.1/24 and
win box is at 192.168.0.2/24
u know, after your last reply i posted that my lan was working.
i dont know why it did, but just a few days ago i tidied up all the cables
under my desk and among others i unplugged the BNC cable at both ends.
i plugged then in again, installed a 2nd nic in my linux box to connect it
to my new adsl modem, and when i rebooted my local lan was (again) gone.
i think its the same problem as it was before (still i dont know), it cant
be the 2nd nic because its recognized correctly, routes are ok and i
already established a adsl conn over it.
so whatever it is.....slowly i am beginning to think it should be in
"x-files".....:)
