Hello to everybody! I noticed a strange traffic to my ssh server and now I would increase its security side. I would to use a double authentication system: the first a host name and public key authentication, and the second the normal password login. In this moment I use only the password login... I tried first, to install the public key system (without password) but my ssh server doesn't accept that configuration. In /etc/ssh/sshd_config I have: ... # HostKeys for protocol version 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key ... #RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys ... # To disable tunneled clear text passwords, change to no here! PasswordAuthentication yes PermitEmptyPasswords no # Change to no to disable s/key passwords ChallengeResponseAuthentication yes ... UsePAM no ...
If I disable the password authentication, when I try to connect I receive the message: Permission denied (publickey,keyboard-interactive). If it is enable, the password it's requires to me. Can someone help me to set it up? Thanks, Luigi -- Public key GPG(0x073A0960) on http://keyserver.linux.it/
