Am o retea formata din 2 calculatoare cuplate intre ele pe 10base2 (BNC)
cu placi de retea 3COM ENTERLINK III
pe unu e kernel 2.4.2 iar pe celalant e kernel 2.4.3 ambele compilate cu
suport pentru 3com. Problema e ca nu se vad intre ele
deci daca depe C1 dau ping la C2 iar pe C2 ascult placa de retea cu tcpdump
imi apare urmatoarele
C1: (ping)
# ping 192.168.25.2
PING 192.168.25.2 (192.168.25.2) from 192.168.25.1 : 56(84) bytes of data.

--- 192.168.25.2 ping statistics ---

Ce sa inteleg din toata chestia asta? Unde gresesc?
Ambele placi is configurate cu softul lor special sa lucreze pe 10base2 (BNC)
Multumesc anticipat
Cu stima,
