uBoot problem

Hi, i follow the tutorial to revert Pogoplug E02 to factory and then...

Edit /etc/init.d/rcS script, and remove the comment(#) in front of the line reading /etc/init.d/hbmgr.sh start

The device response the PING, but putty say :Network error: conection refused, maybe i do something wrong with te vi command

Thanks for your help

EDITED

cd /tmp
