      At the configuration of the SCP-Plugin (at Hudson System configuration)the
      message "Can't connect to server" is shown - but all given parameters are correct.
      The connection via shell SCP is working fine.

          Fixed in the scp plugin 1.4.

          This is most likely a configuration mistake. You probably didn't configure any
          SCP site, or you set the wrong name in the job configuration.

          The NPE occurs as the code is not expecting this failure.

          Sorry, shouldn't sound like a newbie bug report - i tried all configuration
          options, still cant connect to host.

          BUT NOW i found the reason:
          This is a problem of the JCraft SCP implementation, the remote sshd has to allow
          plain text password tunneling - now it works.

          See the following threads:

          Maybe you add a note to the help files about this issue

          Thanks for your patience,

          OK, in that case the real RFE is to support public key authentication for the
          SCP plugin, right?

          Updating this issue accordingly.
