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!
