Permission denied (publickey,keyboard-interactive) in planetlab

Question

I uploaded my public key and tried to ssh to one of my site nodes. But each time I am getting permission denied. Log information is attached.

Please help me if you know what is going wrong.

Try checking permissions on the destination machine. This is the biggest source of confusion. The requirements depend on /etc/ssh/sshd_conf, but by try:

/home/nazim must *not* be world executable (this actually bit me once!).
/home/nazim/.ssh must be chmod 700.
