Hello,
I downloaded and compiled the chat example (go). I run './go 100'
in one terminal, switched to another terminal, run './go 100', typed
something, hit return, and ... nothing. It didn't work. I got 'eth0:
Setting Rx mode to 2 addresses' and 'eth0: Setting Rx mode to 1 addresses'
messages when joining and leaving, respectedly. Any hints?
I guess I have a configuration problem. This are my 'route' and
'ifconfig' outputs:
