Well the thing is that I have used that private key to generate my
public key (did that using PuTTYgen) I do not mention that I've added
public key to "authorized_keys" file and now i successfully login to
the remote server (using PuTTY) with this particular public key that I
use in my php script. So i assume this is not a problem of incorrect
permissions. Perhaps it happens because I use ssh-dss key type instead
of ssh-rsa key?
