I think you're trying to run Gobbles exploit sshutup-theo (tnx to them ;) against system which hasn't got SKEY feature available. BTW: OpenBSD is default exploitable only, cause it has got SKEY mechanism available in default SSH. Some people did Linsux version of this exploit, but I haven't got it, so I don't test it. -- * Wojciech Pawlikowski :: <ducer@u-n-f.com> :: NIC-HDL: WP5161-RIPE * * http://www.u-n-f.com CORE member :: http://www.pot-tv.com big fun * ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
