Hi,

I just found out that something goes wrong within the ARP table (well thats
what i think). I hope someone has a clue..

When i bootup the AmigaOne X5000 with the Ethernet cable connected, it just
never senses the presence of the UTP cable.
I must run the following command as root: mii-tool -R eth0 ... it Resets
the transceiver and the ethernet connection is ready to go.
But then... it randomly dies....

After some digging i found that in a working situation the ARP table is
filled with the correct info. Router address, and corresponding MAC, C mask
and Interface.

(Working)
skateman@X5000LNX:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask
Iface
192.168.22.66            ether   08:5b:0e:fd:db:6a   C
eth0

No more traffic..it just suddenly dies...
skateman@X5000LNX:~$ ping www.google.com
ping: unknown host www.google.com

Rechecked the ARP... and found out it has lost the necessary info.
skateman@X5000LNX:~$ arp -n
Address                  HWtype  HWaddress           Flags Mask
Iface
192.168.22.66                    (incomplete)
eth0

Anyone??? :-)
