Thnaks! When I tried command "whoami" answer was - root

However, when I open SSH client terminal and input there "rsync -av --ignore-existing /home/nemo/system /opt/alien" I am having the same error list I pasted before.

I try to explain it in more detail:
I am using Win 7 64 bit computer. SSH client is "Bitwise". Host is the IP I have under phone developer mode settings (WLAN ip version as USB ip does not connect at all). Authentication username is "nemo". I have choosen password initial method and the password is the same I set in phone under developer mode.

Any suggestions?
