Ethernet problems - ping and lost packets

Hello everybody

I've got a strange problem in the small ethernet network i've tried to
set up recently at home.

I'm using two linux machines, both of them running the 2.0.35 kernel,
and both of them having the 3c509 driver loaded as a module.  The
ethernet cards i'm using in both PC's are the same, namely an Etherlink
III (3c509 combo), and coaxial cable is used for connecting them.  

I don't think something is wrong with the cabling, both terminators are
present, and although the kernel modules do show up with the appropriate
messages at load/initialisation time, i can't get the network up and
running...

Telnet and ftp-ing between them doesn't work, and when i ping the other
computer i get the following output:

bash$ ping els
PING els.home (192.168.0.2): 56 data bytes
64 bytes from 192.168.0.2: icmp_seq=0 ttl=64 time=1.0 ms

--- els.home ping statistics ---
15 packets transmitted, 10 packets received, 33% packet loss
round-trip min/avg/max = 0.5/0.5/1.0 ms
bash$

I've got no idea what's going wrong ...

Can somebody tell me what the problem might be, and what i can do to
solve this?

Thanks in advance!
