Hi Marc, Sarfraz, Dave,

THANKS FOR YOUR ADVISES!

These errors do seems not critical to use communicate with roach now. The
nfs is mounted, and telnet also works. I found /etc/mtab and /pro/bus/usb
from roach, although I don't know why it shows these errors.  Hopefully,
there won't be scaring messages for non-experienced people (like me) :)

Thanks! Will have a good weekend!
