Hi All,
I'm having a bit of a problem using onboard ethernet
card on my mac ppc 9500. I've got 1 ethernet which can
bee seen using ifcnfig and another one is token ring
card which is not configured and I'm not gona be using
anyway so let's not talk about it (;

uogiene# ifconfig mc0
mc0:
flags=8822<BROADCAST,NOTRAILERS,SIMPLEX,MULTICAST> mtu
1500
        address: 00:a0:40:34:ec:16
        media: Ethernet manual
uogiene# ifconfig mc0 192.168.0.1 netmask
255.255.255.0
uogiene# ifconfig mc0
mc0:
flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
mtu 1500
        address: 00:a0:40:34:ec:16
        media: Ethernet manual
        inet 192.168.0.1 netmask 0xffffff00 broadcast
192.168.0.255
        inet6 fe80::2a0:40ff:fe34:ec16%mc0 prefixlen

uogiene# dmesg | grep mc0

so far everything seems fine but when I try to ping
192.168.0.1 from other machine that's what I get:

any ideas what can be causing that? I've got suspicion
that onboard network card in my mac is faulty

this is my /var/log/messages after I've done
#ifconfig mc0 10.1.1.1

then I've entered into kernel debugging mode which I
have no idea what to do there so I've just typed
restart 2 times.
after assigning ip address again I've got these error
messages

after I did
#ifconfig mc0 stop
#ifconfig mc0 start

things seem to be fixed itself I don't get any error
messages regarding to mc0 however I'm still having
huge packet loss
