SSH access for the Xeon Phi coprocessor

Hi,

I've installed the last version of MPSS and I lost connectivity with the coprocessors. My steps to recover access were:

service mpss stop

micctrl --userupdate=none

micctrl --sshkeys=root mic0

micctrl --sshkeys=root mic1

service mpss start

But, when I try ssh mic0 is asking me for a password. If one of the steps didn't work, what log file could I check to find the error?

Thanks,

Paola
