Cannot ping host on same local network -host unreachable

[johnnyQuad]

hi I need some help diagnosing a network problem. I have a gentoo host at home that I access using RDP, SSH, etc. it also is used as a media server using Minidlna. I'm not sure if I made a change or if something else has gone wrong, but the system keeps disappearing. for example , here's ping output:

both the .8 and .31 hosts have a wired connection to same network --and the gentoo host (.31) is up despite being unavailable to other hosts on the same network , e.g. .8 , i tried switching .8 or .31 (or both) to a wireless if --no luck.

not sure how to troubleshoot thoughts?

Please show us the output of the statements below on BOTH machines ( .8 and .31 ):

Can you ping anything ?

[krinn]

Try to output EXACTLY what is on screen from what mike155 has ask.
Your ping output is more confusing than helping

johnnyQuad,

Wild guess ... one of those IP addresses, perhaps both, are allocated to several hosts at the same time.
That's a very bad thing.
